1/16 Mini E-Revo - Top Speed Build

[kazuaki]

I weighed things as I went through this build. My friend's bone stock Mini E-Revo is sitting here and it weighs 2.95 pounds with 2 stock nimh battery packs. The completed truck in the pics above weighs 3.95 pounds with the big packs pictured, a Ko Propo receiver and EZRUN ESC installed. I will not be using the EZRUN, but itis all I had to get the weight. So, it is 1 pound heavier. The vast majority of that weight is the batteries and motor though. The chassis itself is only 100 grams (3.5 ounces) heavier than the stock chassis/receiver box/skidplate combo. If I were to go to thinner metal (likely 0.100") I could shave another 2 ounces or so. I'm hoping the weight won't be too much of an issue for top speed with the powerplant I am running.

BTW, the ESC I plan to run is the Mamba Max Pro that I am waiting on. I'll be running it on 6S.

Another thing you cannot see in the pics. I have made a flat spot on the tranny input shaft. I am using an RCM 4mm/5mm sleeve to run a pinion gear on there. So, I will be running pinion gears on the motor and the tranny. This was the only way I was able to get the gearing options I want in the space provided. I have tested this pinion-on-pinion arrangement in a stock chassis and it seems to work OK. Not sure if it will present any issues or not. Opinions on that?
