The big deal with Lipo is the weight. Less weight = more speed.

The really funny thing is that you can surf these same forums and find threads started by people who are complaining that they got ripped off and are going slower...go figure...LOL
Stop bringing up pesky little things like the TRUTH.

Well good for those guys. Why don't we just start powering our cars with rubber bands?

I am trying to have a discussion on a way to save electric 1/10 R/C. If I am gonna be met will nothing but smart *** remarks, I won't waste my time..

Nobody is talking about dropping minimum weights...right? I thought we were talking about batteries. Weight for weight, motor for motor, a LiPo car isn't going to go any faster than a NiMh car.

The only possible exception would (maybe) be in a very high-draw mod application, where current and low IR is more important that voltage.

I want to save electric too. LiPo/brushless can save electric, but I feel that mandatory voltage reduction across the board is going to do more harm than good overall, that's all.

That's totally fair. I am curious why? Just want a discussion..

A reduction in cost and maintenance is huge. I got back into RC because of brushless and LiPo. It cost me more up front for a 1 Lipo pack and a 13.5 but it has cost me less overall. I don't have to cut comm or change brushes and I only need 1 pack instead of several.

I am not going to take cells off of the packs I have. I like the longer runtime and the fact I don't need more than 1 pack.

If you could run a LIPO at 6.0V, would you object?

Youre right nobody is talking about minimum weights because I didnt mention minimum weights. I said Lipo is LIGHTER thus your car will be faster.

Even if Roar never`s approve Li-Po ....


I`ll never buy Nk-Ml cell`s again ....

So its in Roar`s best interest to approve Li-Po ....

I don't see a need for a reduction in speed for the stock/13.5 classes. If its needed for mod(which I don't run) then go right ahead. Even when I run 4wd I intend to run a 10.5 BL system. I am gearing up for a new buggy to race.

What if you could run a 10.5 @ 6v and it was the same speed as a 13.5 @ 7.4v?

This sounds like an on-road discussion, why is it in the off-road section? As an off-road racer, I don't want to have to change my vehicles/batteries for 5 cells. Most motor sports increase speeds over time/tech not decrease. Look at NASCAR and NHRA.

I say just allow the li-po's and brushless like we plan on doing for the Florida State Off-road series for the 2008 season.

I don't think that 10.5/19T need a reduction either. I raced both stock and 19t touring in the past. Even with a 13.5 now its not really that much faster.

Mod may need to be brought back some. I have not raced mod anything in about 5 years. Even then it was offroad in trucks. I can't comment on things I don't race.
