So I looked through the last few pages of this. I'm a mechanical engineer and could probably help you if I knew what you were trying to do.
If you're looking to slow down the motor and compensate with gearing, I'm sorry to say it won't work. Power and torque don't work that way.
Power = torque x RPM / constant. The constant is different for different units of power and torque. But forget putting numbers to it and just look at how it works. Electric motors put out prettymuch constant torque. So more RPM = more power. Less RPM = less power. If you succeed in cutting your RPM, you'll just have less power and less acceleration, speed, pulling/climbing ability etc.
Tell me what you want to accomplish and I'll try to help. But from what I see, you're just spinning your wheels. (heh)
On my Losi comper I wanted more speed and I was able to get optimum gearing with a stock LNC gearbox and carefully selected pinion. One pinion higher or lower slows the car down.
I get what youre saying and agree with ya. Im thinking any loss I feel in the gearing I can make up for it with motor, a puller 400/500 actually lol.
But going on what you're saying I been thinking about the same after running my original tranny. Its one of the reasons I aimed to have different gearing options just by swappign two gears.
Im thinking the trials are gonna start out along option one in my post before and go with the 16-17t pinions to start. It should keep me close to the LNC tranny and get me some good baselines to start off.
Ill def keep posting here and will always welcome the input "thumbsup"
On the other note of practice ..... I did get it out Saturday. Over all I was happy with the truck. I did smoke the b1r escbut I was really thinking it was gonna happen anyway.
Over all it held up to the runs. I bound the front end up and really just tried to throttle out, the esc didnt like it and the puff of smoke told me. Trial and error but never know till you try.
Gonna take my rear limiters from 6mm down to 4mm for a little more articulation. Oils felt good at 80r/35f with RCBros springs all around. Traction on the dusty rock was not a problem.
Had a little push on the first run so I raised the rear upper links to the top hole .... push gone.
I also had a really light rear end that was letting the front axle just toss it around. Front bite was good and I could have added a little weight to the rear but I went with actually tuning it. Took the front upper links from the top hole down just one. Take some weight and transfer it to the back a bit more. It worked, rear follows the front now and doesnt want to just flip over on decents. No front bite loss .... I love tuning. "thumbsup"
But ordering a new esc this week and more testing coming ...... Front axle held great, the axles never got that warm at all which was a plus. Hopefully the snow will be gone in the next week or so and I can get some real testing in.
Felt good to have a Losi back out there.
