Re: Li-Po setups

thanks for that PH2T

Suspension is a big thing. It can just be too fast to dampen well.

i just got in my kyosho oil damper from hobbyjapan. it kicks arse! i noticed both you and BETTYK had one without a spring. works wonders.

Grip is also an issue. You need some really nice soft n sticky foams to get that power to the ground and keep it there.

i have a pair of medium foamies on the back so thats not too bad. the setup i like best is getting the pinion gear right so that at full throttle from stand still i dont spin out. its getting some great speed. im not really to good at handling it though. today i turned my 0 deg knuckles into 10 deg knuckles with the help of those reflectors on the road lol. got some serious air!

That won’t work. The reason why is that the mosfet gate voltages don’t fully alternate between GND (0v) and Vcc (4.8v for 4 cell nimh). Whilst I won’t go into the full details, you will find that both the p-chan mosfets on your turbo will always be on. When you apply throttle you will create a short circuit along one path of the h-bridge and blow the turbo.

yeah this is one of the few things i remembered about transistors from 2nd year lol.

I use MOSFET drivers on my nelly deluxe to achieve a similar (but more effective) result. (MOSFET drivers are suited to turning on MOSFET really well, really fast, really hard!)

yes i like the sound of that! that is originally what the electronics guy was telling me to do. he didnt like the idea of using a p and n chan mosfet though. what mosfets do you use? im not too sure how you feel about sharing your hard work but if you were willing to tell me how exactly you set it up i would really appreciate it.

and about those polyquests. i have been doing some research and found these. they dont seem to be the same as yours though. are the dimensions the same?

thanks for all the help
