    Thanks for watching my latest video! I had 2 things I wanted to try on this, ordering an RC from TEMU and also check out this model from SCY or SUCHIYU which is unfamiliar to myself. TEMU ships must faster than Banggood or most vendors from Aliexpress, this arrive in 1 week from ordering to me here in Canada. Also I'm very surprised at the build quality of this model in many aspects (lots of metal parts!) Overall I'm quite impressed but I want to know your thoughts too. Let me know in the comments! See you soon on the next video.

    I run mine on a 3s 1500mah 45c lipo and it's insane! Mine really needs a wheelie bar now.😁😁😁 A set of oil filled aluminum shocks are only around $20 and make a huge difference in handling. The ones for a WLtoys 124016 fit nice! I hear their coming out with a fully upgraded version soon with all aluminum arms, tie rods, and oil shocks. 🙏♥️

    Awesome. I can only imagine how stupid fast it is on 3s. I might have to try it myself but I have very few 3s lips and not sure I have one that fits. We'll see though. Quality oil filled shocks definitely help! I have some on order that fit the wltoys 144001 so they are probably very similar to yours. Thanks for the news. Glad you are having a blast with this truck. Cheers!

    These SuChiYu RC's are pretty good value, i have quite a few models. The only down side is like you said, they have friction shocks still. those preload C-clips they provide for the shock do help a little bit but still tend to be bouncy just not as much. The performance of these brushless models is great though, great look at this one Mike, have a good weekend buddy!👍

If you want to run everywhere go with the MJX truck.. it's more durable and easy to get parts too if something eventually breaks. For $150 budget, make sure you get the brushless model of it. Don't worry man if you are like most of us, you'll keep adding to your collection of RCs and own them ALL! haha! Hope that helps. Cheers!

    The radar is a hockey shot radar... you place it behind the net, take a slapshot and see how fast your shot is. Works great for RCs. It has both KM and MPH. I'm here in Canada and use KMs for speed. So in terms of this video - i'd be talking about hitting 60km. In scale speed 16 x 60km = 960km per hr which is fast... that's 600mph scale speed. If your felony is 60mph, 60mph x 10 = 600mph scale speed, so these are virtually the same in scale. Sometimes on these smaller RC with big wheels sticking out I wonder if it reads the wheels turning speed. Overall though it's pretty accurate. I also have a handheld speed radar but I can't do it and drive at the same time. I will be getting my son to help he's old enough now.

  • @kultus26

    Hi just want to ask. In your video you break the car at 10:17...is it normal sound and quickness of breaking process (pushing backward throttle on remote control)? Because when mine was new it was breaking super fast even from really high speeds it stopped almost immediately, but now it breaks like your one, slowly with that howling sound. Is it normal? My car seems dangerous at high speeds as the breaking is unreliable. THX

  • @mikesrccorner

    @mikesrccorner

    4 күн бұрын

    That is going to be normal hearing it whine when breaking. If you double brake it goes into reverse so that would make it stop extremely fast. One thing I would check is your throttle trim. Make sure it's in the most neutral spot. You can play with it with not touching the throttle on the radio and dial the trim up so the RC begins to move fwd... back it off and keep going till the RC goes in reverse... once you find that range, trim the throttle to have it in the middle as best as you can so you will have proper throttle and braking. This RC is a bit louder than most at this size but it has a lot of metal which the cheaper RC are plastic. So it will make more noise. It's a great RC and with a little maintenance it will last a long time and have fun. Hope that helps. Sorry with a delay answer... I was away on vacation last week.

    This model goes under a few different names but uses the same OEM. Could be some minor differences here or there. The PRO is the brushless of course and the cheap models are brushed motors. Be careful when buying on Aliexpress, I love Aliexpress but follow the pictures when clicking on a selection because the RC you select does alway match the title of the ad. Cheap models are brushes and say 50km and the higher priced you see 70km and are the brushless ones.

    I own the "pocket radar" and I took this to a friends house, we ran this car on a 2s lipo and some better wheels and I clocked it at 38mph = 61km. Check out video episode 648 in my channel for that update.
