Would be intresting to do some testing with LiPo and 4 cell.
I think you would have to add a huge amount of weight though if both where to be used together to even it out. If you think about it, 4 cell is 4.8V and using a LiPo is 7.4V, thats means the LiPo has over 50% more volts than the 4 cells as well as being lighter to start with
Also I dont think the motors that come with the Mardave kits are the longest lasting things in the world, running them on higher volts means higher rpm, which means they wont last as long. Going through one of those a month will soon add up over the year...
Have been looking at the LiFe batteries, these run at 6.6 volts, from what I have read they dont 'blow up' like LiPos and you dont need to worry too much about running them low. There is some small ones about that you can use as recieiver packs in nitro cars, I dont know if these would have enough in them though to last a race
I like the idea of adding weight to the leader in the final, we could run a reverse grid in the final, would be good fun if we had a large final
