I would like to know if anyone has compared the weight of a NiMh 1600 5cell flat reciever pack up against a lipo reciever battery.
Also, I have read that some of the pro's do not use regulators with the lipo's as the servos can handle the higher voltage. Just want to know if anyone runs them without a regulator.
lipo is the way of the future, nitro and electric but it has its issues.
a 2/3AA 5 cell pack is more than twice the weight of the 1300 lipo cells around but then you need a regulator. the last time I had both out of the car and weighted the 3, the difference was about 40 grams which went into a brass battery plate at the lowest possible cg in the car instead of above it.
You can run without a regulator, but only a few servos (ace I think) actually say they support it while many will work but not for long. As for the trouble with regulators, ask Ryan Maifield and Associated about them when he had a lap lead on everyone at 2007 offroad nationals and he was taken out by something faulty in the battery system and if you look at recent shots of his car, its NIMH. I personally have run the same regulator for over a year and it's been fine but mine is in open air, people think they die because of heat and I believe the only failures I've heard of (from any brand, they're all similar) have been in offroad cars in receiver boxes or in onroad cars with no access to clean air.
