RE: VIP
The 2 turn would pull way too many amps for the lipo's. If you want to go that route, you will need to use round cells. You might be able to fit 10 gp1100's in the fuse, but you will get a fraction of the runtime. It will be a heavy setup which means harder landings, but it will be FAST! You will also need a bigger controller.
Check out my VIP video and see if that setup is fast enough for you. It is a nice light setup with lots of runtime and speed. You can definately go faster, but then you are looking at much heavier setups which sacrifice runtime and flyability.
I'm moving to round cells and lower turn in my sunracer. I'll see if it was worth it and let you know.
