The smaller tires impact your final drive ratio a great deal. I put buggy tires and wheels on my Foxx 911s to attempt to make it controllable and lost several kmph.. On the up side, it's controllable now.

I'm really grateful for all of the detailed reviews, and stress-testing, you've done regarding the 9125 over the past couple years! I've been in the market for an inexpensive but capable RC basher with readily available replacement parts to use for fun and as a GoPro platform for shooting B-roll for my KZread channel, and your videos have helped give me confidence to buy the 9125.

Cheers brother, I always like to push these cheaper RC's to the limit and see what they can do and share! 😎👍🍻 Cheers for watching as always bro!

It is possibly the improved torque is due to the fact that you have a battery pack upfront which prevents the truck from losing forward motion torque to wheel/front end pop up. Also the heavier batteries put more weight on all four wheels so they don’t spin. The smaller diameter wheels help with this as well (but as mentioned by others is cutting into the top end speed).

I'm shocked it could handle 5s but looks like it is maxed out so 4s looks best. You are the king of the speed tests David!

How did you remove the ESC cover? Does it increase cooling? Maybe it would be an idea to put a fan on top?

what is the difference with the outside diameter of the original tyres to the ones you used in this test. I'm suspecting the replacements are smaller which would then affect the overall speed. at the very least if they were the same a ballooning tyre increases in diameter which would result in higher speed runs.

@PERTHWESTOZRC

Yes these wheels I just put on to experiment if this truck would handle 5s.. Top speed suffered as a result. I later followed it up with another speed test on larger wheels and tyres which improved the overall maximum speed. Thanks for watching 👍

It’s geared for the taller tires. Having the short tires increases wheel speed, but decreases top speed of the vehicle
