Ok so here is a question from me...
We been very limited up to now on which LiPo batteries we can use for 1/12th... Well not anymore so... for 1/12th Modified what would be better a higher mAh like 5600 - 6000 with a lower C rating like 50C or a lower mAh like 5400 with 60 - 65 C rating.... Can't find a battery with both and I am guessing higher mAh is better for runtime... Any thoughts

Thanks
:):):)

(my experience with voltage reducers have not been good. i have 2 for 2 failed. i had one fail at the start of the back straight on my gas car. if it had failed 1.5 seconds later it would have been very ugly. the lipo pack in my transmitter had a voltage reducer built in, which died while stored between races)

My Spektrum receiver is rated up to 9.6v. As far as I know Tekin is the exception and most stuff can handle 8.4v. People are running their Tekin's with 2s lipos despite the warnings and are not having any problems. You can drop the voltage to the ESC using diodes if you need.

Generally it's not the receiver you need to worry about, it's the servo.

Actually it's all 3, reciever, servo and esc. Having a 'blazing' fast servo is great until it lets the magic smoke out:eek:

Did you not see my comments about the diodes and the 9v Spektrum receiver? Check your specs people. Sounds like a lot of companies aren't "up to speed" yet.

BTW, I love my Copperhead 12. Best 1/12th pan car ever.

Got a question about diff rings- the 'indentation' that forms on the rings from the balls, is that desirable or should that be sanded out?

Are they actually grooves or just a discoloration from where your balls are wearing?(yeah I said it:eek:)
