8.3.1.8 Unless otherwise specified in the class requirements, a maximum of six NiMh/NiCad
cells or 2s 7.4v nominal lipo battery is permitted in any vehicle motor power pack used
in ROAR-sanctioned competition.
from the pdf version of the roar rule book on page 32. the pdf can be downloaded from their site.
So, it dawned on my that I needed a 3+ channel Tx for my Hilux, and this is being built semi-period correctly, so an AM stick radio I went looking for. I found myself a close to new Futaba Conquest FP-T4NL with (Futaba G, FP-R4F) Rx on Channel 80...

So little bit related to the topic, what is the deal with surface use only and non surface use radios?
Money. Surface use airwave licensing is priced differently than aerial use. It's why you're told to turn off your device on a plane. Nothing...

If you ever consider switching to LiPo's, a cheap US surplus ammo box makes for a perfectly safe storage case! :wink: this is true i have a friend that does this and stores it in his garage..
its so funny everyone is just trying to protect the house...
What is the best nimh battery? I'm looking for a preassembled pack that's 7 cells and preferably at about 3000 mah. I don't have the money or means to run a lipo, so what brand will give me the best battery life and run time for the least cost?

I run lipo batteries through old esc's with no issues. The old esc's do not have lipo low voltage cutoff though so you either need to purchase a separate cutoff or an alarm. A simple alarm that alerts you that you should stop running is as low as $5...
Can anybody explain the pros and cons/differences of Nimh and nicad. Can both batteries be charged using a Protec 702 charger? What would be best for running around the backyard (no racing)? Also, what mAh and volts would you recomended for putting...

if the nicd only Portech 702 still works.. id say buy 2 of these cheap fun 8)
So I was out in the yard with my 10T. I put one battery through it and a friend came over and one thing led to another and you guessed it, I left three packs sitting on the back of my car. The next day after a mild frost I discovered my batteries....

Back in the days of NiCd/NiMH, there was a machine (forget the name but looks like a jumbo size charger) that could litterally zap a dead/frozen cell back to life. Sneeky racers would use it to get a little more juice out of their packs at the...
My RC history is all with NiCd batteries. For them, the general rule was to fully discharge before recharging. I'm using NIMH now because I'm not quite ready to jump to Lipo batteries. I'm not really sure what proper cycling and conditioning is for...

Out of curiosity, why? If running standard 7.2v 6-cell NIMH packs, they make 2S Lipo packs that are almost direct replacements from a size and appearance standpoint.
Speaking for myself.
Only five (of 20+) of my esc's have lipo cutoffs (I know...
I would like to build a battery pack and was wondering what are some quality AND a relatively inexpensive sources for sub c cells? I have found some Ultracell 3300mAh cells, but I have no idea about the quality. I absolutely want to avoid the cheap...
When setting the amp rate on my peak charger for nimh packs, I've always used the mah/1000 rule to set the amp rate on the charger. Example: 3000mah/1000 = 3amp.
I've recently read that it's safe to charge at twice the base rate, meaning...

Thanks for the clarification guys! Much appreciated.
