Hey Mike, Thanks for the compliments, (bows head modestly) I'm trying. :) The wall of flight needs more! lol I think a scratch built motor glider would round it out quite nicely. And I used e-calc the other day to try to put together a 90mph plane powerplant for a second aircraft. I'm not sure...

So because the Mini 8ight has been a huge pain with all the excess heat even when using the manufacturer's recommended gearing for a 2s lipo, I've come up with this to solve it and make it run more like the Mini 8ight DB which has the higher torque motor and doesn't overheat even after 8 packs...

Oh then you'll enjoy this reading material. so you put in the pinion and spur and it does all the rest basically.. Motor KV is known, as is internal drive ratio (differential ratio as listed on the specs) Voltage is a constant as well. After that the chart essentially divides the spur by the...

I agree, It is a respectable speed, to be sure. so here's what I figured out. for about 60 total for each buggy, I can put the 3800KV motor they use in the Mini 8ight DB, move the 14 tooth pinion over, to it, and put a 62 tooth spur gear. I'll upload my excel file.. it has some calculations in...

Agreed. My only thought is maybe I drop the 58 t spur for a 60t spur and then the 12 tooth gear will be 5:1 drive ratio, but final drive is a mystery.. I suppose I could figure out what makes 9:1 .. that math is not easy though.. I'd have to start with the stock gearing to find out what the...

I've double checked the set screw on the motor and used the piece of paper technique between the gears to make sure there was no binding. I'm using the manufacturer's spec.. I could put a shorter pinion gear on, but that just takes away from top end and the motor still gets hot. I'm sure the...

So I bought the Mini 8ight and decided I'd like to know what the stock top speed of this thing is on a 2s lipo once you change the gearing to match the recommendations in the manual. Here are my results. Even running the stock motor with the correct gearing this motor gets hot.. and I mean...
