thanks Nick that explains a lot to me which helps me on my battery purchase

We run WGT-R 17.5 1s .... i was running my 17.5s at 5 to 6 amps on large open tracks...on a small local track i needed 3/10s i searched high and low for it, i ended up turning my timing back to 3.8 amps .. i picked up my 3/10 i needed ..... as the timing goes up, the power band is narrowed and pushed higher in the rpm range ... more mild timing gives better midrange torque and a wider power band.

Hi nick , would the 6A sweet spot be applicable when using a 1S Lipo ?

Hi Nick, definately found this very informative, and I agree on the 13.5 and 17.5 motors around 6A is the sweet spot, I saw you mention in a reply 4 Amps for the 21.5, from a bit of testing I am finding 4.5 Amps is probably better for that wind motor, tried it on the Fantom FR-1 and the Trinity 24K and seems to line up with where the performance was.

Hi Ben I am not sure for that motor, but temperature is always useful to get the FDR right. If the motor is hotter than 70degC then it is close to maximum. If it runs cooler then you can lower the FDR. What wind is it? A 17.5T, I would start with 6.0 It depends on the track size etc, so you will have to try it.

thanks nick for your help. I also have a question on speed controls is there a way to test the fets? Sometimes i feel my setup on my car is good but i have no punch coming out of the corner or like im not getting full power or i feel like im over geared no matter what pinion i run or maybe its the motor. What would make me lose speed like that?

@nickadams5411

8 жыл бұрын

+Seven 420 Hi Loss of punch as the race goes on is caused by lowering voltage of the Lipo or overheating of motor or speedo. Overgearing will give a fast car at the start, but will slow towards the end. Make sure your Lipo is the best you can get, and that it is not out of balance., especially if one cell is always lower than the other, then it will never be at its best. Check the heat of the speedo and motor after the race. Keeping them as cool as possible will give performance all the way. If the speedo is hot to touch, fit a fan (or get a more powerful one) If the motor is too hot to touch, get a more powerful fan, or change the gearing/timing. Note that some motors lose magnet strength over time, which will cause overheating as well as lack of punch. Spin the rotor over by hand and feel that the magnet is still nice and strong, and stops quickly . Some rotors will feel mushy when they go weak. Testing speed controls: It is very difficult to test if any FETs have gone down, as there are several working together. Trying to measure the short circuit current delivery is very difficult without damaging the speed control. Also it is rare to have some Fets go down, unless the speed control has been shorted or connected reverse polarity. Hope that helps. Nick

Hi Nick.. Can I use the analyzer with motor wired to esc? Cause its take more time for me to re-soldering the A B C wire 😁

Hi Nick! Do you think I can set the timing approximately correct just using an ammeter inline between my battery and the ESC? Obviously there will some additional current through the ESC BEC system but if I set to 6 amps, would that be an ok poor-man's method to set the timing? On a different note, my wife thinks your voice sounds like the narrator from the snowman! :) Kind wishes, -Tom

Is 6amp current draw arbitrary for all motors? I'm just setting up a new GT class car (blinky) with a Hobbywing V10 G2 21.5T motor and wondering if setting timing for a 6 amp unloaded draw is correct. I'm just using a Fluke multimeter (ammeter), I don't have a motor analyzer. If it's not, what unloaded amperage should I be aiming for?

Hi Tu I am not sure that this is much use to rock crawling. It is intended to get maximum speed and performance, without burning out the motor. If you are driving slowly then the torque is more important, as you will be geared for small changes in speed. However you can still set the motor with a 2S lipo and then it will be ok with a 3S lipo. As usual always check the temperature of the motor after a run, to make sure it is not too hot.

Once you have found the sweet spot in a motor, if you add more timing via the esc will that " add up" so to speak and overheat everything?.

If you have time, start with the timing low and then keep turning it up a few degrees at a time, until it starts going much faster, but motor is not too hot. If you turn the timing too high, the car might jerk (cogging) when trying to accelerate. Turn the timing back a few degrees until that stops. Hope that helps.

Hi Nick, love the video's for the 17.5 and the 13.5 timing to the sweet spot. My question is why would 6.0 amps be where the sweet spot is found? I race blinky on a clay oval in both the 17.5 and the 13.5 with an Associated SC10 modified/Late model body and both required the timing advanced all the way to achieve close to 6.0 amps. I am concerned that for a 4 min race I will overheat and burn up the motors. I was previously running about 35 degree timing at about 2.5 - 3.0 amps and the motor geared at 25/75 with the temps in the 160-170 range.

Hi Bob I originally did this video for on road touring cars, which race at fast speeds. For Off-road the settings may be different, especially as the motor is enclosed and will heat up. The 6 amp spot was found to be just before the rotor losses became too great and the efficiency dropped quickly. I suggest that motors should be checked for temperature, and if too hot, and can't be cooled with a fan, then adjust the timing down , and make sure the gear ratio is correct. If the vehicle is stopping and starting, then the motor will heat up much more. If the motor exceeds 80deg C on the case, then it is too hot and will either lose power or burn out.

@nickadams5411

Hi Fabio. Hi Fabio. 4 pole motors are not normally made for high speed tuning, and have only a small range of static endbell timing, (some are not adjustable). The maximum timing advance is half that of a 2 pole motor. So it will be limited to about 30 degrees. So the maximum safe advance will be about 25degrees. However the amp draw may be way off. So you will have to do it in steps. The castle 3800kv is a similar size to the 2 pole, but will have a higher static winding resistance, which can result in more heat. You can tune until about 6amps. However the matching ESC normally has special boost timing programmed for maximum performance. Therefore you should not use both methods at the same time. Otherwise only try it in small steps and check performance against motor heat. Race on. Nick

+ryan holcomb Hi Ryan I have the same Certified motor. The figures were nothing like my measured ones and I ignored them. The resistance of the ABC coils varies so little between all production line stators (of the same make) as to make no noticeable performance difference. The stator Gauss figures (magnetic strength) are the North and South pole, and should be as close as possible. In practice all production line stators are close enough and the actual strength can vary but have no affect if the motor is set up. The magnetic strength will change after some hot runs anyway. The revs will depend on the enbell timing, and I assume the test revs are checked at 1.4volts and 7.4volts. The sweetspot amp test will sort the motor much more accurately, as the endbell timing marks can be way out. Especially as the sensor boards can be way out on the ABC timings. They should select sensor boards with only +/- 1 degree out. My Certified motor had one sensor 8 degree out ! In conclusion, I have found normal production motors better than the certified one. Hope that helps. Race on. Nick

Hi The FDR should result in the motor hitting maximum efficiency about half way down the longest straight. If you over gear or under gear the motor will run at a lower efficiency and will heat up. 70 deg C is ok, but if it gets to 80C then you are not geared right, or too much crashing.

Thanks for all the help - come to find out I blew a fuse. Once I dropped in the new fuse and followed your directions I was able to tun my motor. My 17.5 Team Powers motors was pulling ~11amps - now it's tuned.

Hi Todd That's good news. Hope you get some good racing now. Nick

Hi Nick, After me and my friend watched the video we tried this on my 17.5 buggy it is really much faster. I also run VTA which is 25.5 touring car, what would be the target amperage for it?

@nickadams5411

Hi Robert Great, you are going faster. The 25.5T motor is very inefficient and will overheat if you try and get too much out of it. The VTA are also heavy and probably do not run, handle well, so have some stop start action, which will heat the motor. Test it first and see what the amp draw is. If it is very low, say 1 amp, then turn timing up to say 3 amps and try and see how hot it gets. If all good , try 4 amps. I think 6 amps will make it too hot. Also it may be able to pull a smaller pinion at the higher amp draw, so it is a bit of a too and fro to get the best compromise. See how you get on. Nick

Hi nick. Just tried this with the motor in the car. I ran the motor straight through the esc as if running it properly and it seemed quite quickly. I then ran it through the multimeter and the speed of motor dropped and, according to multimeter, it was only drawing 2.88 on the DCA setting. Is there anything I done wrong?

Hi Jason The multimeter may be dropping a little voltage, especially as you are using 1S make sure the connecting wires are heavy duty and short. Setting with 1S is much more difficult than 2S because of the voltage drops. When setting for 1S (blinky), i did a video saying it is best to set it with a 2S lipo and then it will be right for the 1S Hope that helps nick

Nick, from 6amps there are no benefits, right? My motor (x20 13,5t LRP) is draining 11 amps, it will be better to lower the timing? My use is for Touring Car 13.5 blinky mode. limited to 4,5 FDR.

+Marcelo Borges Hi With fixed 4.5FDR, drivers push the timing until the motor gets too hot and burns out. I do not like to go over 10 amps, so try 8 amps. The amps changes a lot for just 1 or 2 degree change of timing. If motor overheats and slow down towards end of race, the lower timing .

Hi Chris Not normally for a 25.5T High winds have high winding resistance, and poor efficiency. Depending on the use: 2S and weight of vehicle. You should time the motor and gear it so that it runs no hotter than in the 70 degree C range, measured straight after the run. Assuming you are running Blinky (No speedo timing) I suggest you set the timing at about 45 degrees, and measure the amps, which should be less than 6 amps. Try and find a gearing that gives good performance for the track. Measure motor temp, and if not hot you can either gear up for overall performance gain, or increase timing by a few degrees for higher top speed. Then check temp again. Repeat as necessary. Note that a powerful motor cooling fan is essential on high wind motors, as they will generate heat.

Will 6amps work on a 10.5 as well or is it higher or lower

@nickadams5411

+mrskaterdude75 Hi If it is for 10.5T blinky then the timing will be lower, to get about 6amps. The 105T will run more efficiently so try 8 amps. Always check the motor temperature after the run. Adjust the timing until it is just getting hot.

+Nick Adams great thanks will try that, and I also have a 21.5 what would u recommend on that for amps because I am getting about 1.5 with zero timing

hi nick its me again.. assuming we have understood all the values.. what is the maximum temperature we should have? 60, 70 or 80 degrees perhaps? do you gear your car base on race time or temperature?

@nickadams5411

8 жыл бұрын

Hi I gear for best acceleration and top speed. If you set FDR too low , then acceleration out of corner is slower and motor will heat up. Motor temperature must be kept below 80degC measured on case after race. If your motor has a high rev per volt (KV) then the FDR will be a higher number than a lower rev/volt motor that has perhaps a stronger magnet rotor.

Hello Nick,I didn't see this question asked but why is 6 amps the sweet spot for 17.5? How did you determine this. I just checked my Trackstar motor. With the timing maxed out it was only drawing 1.5 amps. I modified it and is now around 6 amps.

@nickadams5411

8 жыл бұрын

Hi David After running in the 17.5t class myself, I managed to check the fastest cars and found that they all were set around that figure. I then did some tests and found that once the timing goes past a critical point the amp draw rises quickly but with very little or no extra performance, and generates a lot more heat. I set the amp draw at 6 amps, as that works for everyone to give them a competitive motor without going too far. Experienced racers might push it a bit more, but just an extra 1 degree of timing can make the amps go up 2 or 3 amps. That will require driving on tracks that always maintain high speeds. So 6 amps is close enough to the maximum, and has proved to be good in the races. The FDR (final drive ratio) must also be set correctly for your track. On a large track it will be about 3.5. I have seen 3.2 to 3.7 spread on most normal tracks. Small indoor tracks you will need to check the motor does not overheat (over 75deg C) and set the FDR higher. Hope that helps Nick

@nickadams5411

7 жыл бұрын

Hi David. For Blinky , the timing is set to give maximum power at maximum efficiency. There is a timing point where a small increase in timing results in a rapid increase in amp draw, and a drop in efficiency, which in turn results in wasted energy which turns into heat in the motor. In practice 6 amps is very close to that point on most motors, and will give very good performance, with the right gear ratio, on most tracks. Of course, the experienced racer may want to push the motor harder, if the wasted energy is not a problem. But setting your motor at 6amps will get you in the ballpark and close to the quick racers straight away. Hope that helps. nick

@bobslavik6109

I think Nick is referring to the ratio of just the pinion/spur on a b6 you are correct the FDR also needs to calculate the transmission diff internal ratio of 2.6. a good staring point for you pinion/spur is 25/75 to give you a FDR of 7.800 then adjust for temp. Also a good rule to remember is going up one pinion size equals about the same as going up 3 sizes on spur. Depending on what you are racing on a FDR between 6.964 and 7.800 will get you competitive.

Hi Rob The start up current is quite high, so advance the throttle slowly until full speed. The meter can do at least 10amps DC? Also check that the meter conecting leads are not too thin, as they will drop voltage and give low readings.

It might have happened on throttle up...I'm not really sure. I wonder though, if I dropped the current limiter on the Hotwire, would that possibly help prevent popping the fuse? And / or , will lowering the limiter affect amp draw?

@nickadams5411

Hi Rob The fuse should not blow if you advance the throttle slowly until at full speed. (As long as current draw is less than 10 amps) Setting the current limit to minimum may help if still blowing a fuse as it accelerates.

So I have just started learning about motor timing and stuff, and to my understanding, the only reason to change your motor timing is to get your motor to draw 6 amps? Correct? And then AFTER that you change your gearing? That's my understanding so far, correct me if I am wrong!

Then just read the DC amps on the display. Anyhow, keep trying and you will get there. Nick

Hi There Nick Quick question I hooked my ammeter up as you showed on my cars and both draw under 2 amps.

My only other motor is a Speedpassion 17.5 and that had been reading about the same. Wires are all 12AWG and the amp draw besides the motor was comparable to your demo, 0.7 with my cooling fan running and 0.1 without up to 0.2 if I turned the servo The timing definitely has an effect as set to minimum the motor amp draw reads as 0.8
