R/C Tech Forums - Tekno SCT410 Thread

Seeing as how I just smoked my 2nd RX8 in a month, you just may be onto something with that theory. I'm of the opinion it's the most powerful ridiculous 2s motor, but probably not the best choice for most people :-)

On my first ebuggy I was running 2200 kv on 6s and turning down the EPA to make it driveable. Burned up a couple Mamba monsters. One almost burned my buggy to the ground. Talked on the phone with one of the engineers at castle and he said turning the EPA down is no bueno. Puts too much stress on the esc since the fets are always switching and builds heat. Idk the technical details about it, but figured he knew more than me so I went to 4s and 100% EPA and never had another problem.

No not in the SC yet. It would require a motor mount from the EB and we havent had a need for such a thing yet. Its possible though.

Shark on his SCT D8 Tekno conversion I beleived used the mech brake and really like it. who knows, maybe with how hot motors are going, could be a way to keep temps down on the motor and ESC if I recall correctly how well that mech brake helps in 1/8.

I'm gonna get the Tekno conversion kit for my SC8e and try out the mechanical brakes myself...I've been wanting to try it....I believe I would need to get the Elektri-Clutch to use with it, right teknorc?

I beleive if you use the long shankpinions, you can use the mechanical brakes as well.

Paul,
Are you thinking of getting one?

You can use mechanical brakes with direct drive, traktion drive or elektri-clutch.

How does the Mechanical brakes work WITH direct drive?....Wouldn't you have to have a clutch spinning the motor shaft freely while the mechanical brakes stop the vehicle ? (like in Nitro Vehicles)....Direct drive would eliminate the use of mechanical brakes because the motor stops the drivetrain when the brakes are applied already...Am I missing something here?

OK, Kool....I never thought of that....but you would still need the Tekno chassis conversion I believe....the way AE sets up their E-vehicles, it eliminates the throttle/brake servo and puts the motor and motor mount in it's place....don't see where you can pull this off without converting...

I call BS on the EPA setting. There is no difference as far as the ESC is concerned between a trigger at 80% with 100% EPA, and the trigger at 100% and the EPA at 80%. So what he is saying is someone who only ever hits X % of throttle messes with the fets. Gotta love BS'ers who pretend like they know things because they figure you will believe anything they say.

And since he had to make things up, that tends to indicate he is defending a shoddy product, or at least one that can't live up to expectations.

Lol. Ok.

I think you missed the change from 6s to 4s being what allowed for 100% throttle usage.
