As long as throttle_gain is 8 more than the pwm_gain each time.

Howdy,
Been enjoying this thread for a while. Finally ordered a kit today. Going to run it in a 1974 Citicar. Can't wait! If anyone else is building a controller in Austin, Tx., feel free to PM me.

Yo! xtian999! Wazzzzzzzzzzzzzaaaaaapppp! You are going to run it in a citicar?! Aweosme! I am guessing 0-60 in like 1 second if you can get 144v, since it looks so dang light. I can't wait to see how it turns out! ya!!!

Yeah, It still has the stock 6.5 hp serial-wound motor with only 3K miles on it. Since that will be the weakest link, I am looking forward to replacing it with ???. Actually, if you could suggest a motor that will use the full capabilities of your controller, we can see just how quick/fast a Citi can go.
The stock diff will probably go away at some point, so don't let that limit the choices.
Thanks,
Xtian

Citicars become relatively unstable over 50mph, my commuta I have had up to 65mph ish going downhill with no regrets. If you really do have a citicar and not a commutacar and you plan on driving freeway speeds I would recommend moving the rearend differential back so you don't pop wheelies on the freeway cement pieces. Even my comuta with its longer wheelbase will start rocking after a while on a cement freeway if I don't coarse correct into a crack every once and a while.

Stock wise comutas running 72v can typically go 45-55mph depending on motor, tires, etc.

The only motor I know of that upgrades a comuta (or citi) is made by D&D, if you call and talk to them you can find out the largest for your car.

Supposedly the motor in my comuta (from D&D) can be overvolted up to 120v from the rated 72v but you need massive cooling and I would estimate the life of the motor is decreased.

Cheers
Ryan

On my car when I would get all 4 wheels off the ground over the railroad tracks sometimes the seat would slide forward and I would end up slumped down like a midget and usually end up stopping to move my seat position.

That and its also hard to steering with your car doing the Mexican pimp car action down the freeway
