Default 3PM-FM settings for RC Electric Drag Racing

Dear Futaba Support,

I need help in determining which adjustments on my 3PM actually affect throttle performance on my Top Fuel electric dragster.

R2E (the car) uses a 3PM-FM radio with R133F FM receiver. Motor is Novak 4.5 HV sensored brushless. Controller is Novak HV-MAXX. Battery Power is Thunder Power 3s x 3850 LiPo. BEC is provided by motor battery with a Novak 'Glitch Buster' capacitor on B/C port of the R133F. I do not use a seperate receiver battery.

I broke the code on the ATL brake setting and can successfully alter braking pattern on the rail to keep from shearing rotor shafts off during shutdown. What I need help with is if and how to adjust throttle. I'd like to 'soften' the launch, then deliver full power beyond the 6ft mark. Can I do this with 3PM FM transmitter settings? How? My controller profile is not adjustable.

Reading the instruction manual, it seems a lot of the settings are for use with nitro, e.g., throttle servos, and will not migrate to use with an electric ESC/Controller. I am digitally challenged, so maybe not really understanding what the manual is instructing me to do. Appreciate any help you can provide. I feel there is performance gain in the 3PM for my car, but don't know how to get it.

Regards,

Hi AHR43,

If you were using Nitro, I would suggest you use Expo-FW, and set a negative amount of Expo to the forward throttle to make the slower response on take off.

When using an ESC, I believe you are at mercy of the Speed control.

It may be better though to have some of the car guys see if they can help you out, so I am going to copy this post over the the RC Car Radio Equipment forum for you.

Good Luck,

Well, that didn't work out too well did it Futaba?

RC drag racing is a niche sport within RC. Not suprised there are no replys. That's why ahr43 went to you all in the first place.

No problem. I'm working it out on my own.
