I ran my GTP the other day on 4s (set up for 10s, but the cells aren't in yet), and even though it wouldn't get fast enough to shift, it was really hard to keep from spinning those tires. Then, this evening (in between bouts of rain), I made up a quick-n-dirty harness to tie 4 2s packs together just to see. Well, I got it to shift all right, and what people say about on power shifting is correct; all 4 tires broke loose and started to fishtail. Was able to get it under control, but barely. Man, this thing was FAST (no GPS or radar to verify)!!! I'm sure the damp road conditions didn't help.

If you go with the 2 speed, make sure you have really sticky tires. It might help to keep the difference in ratio closer together so there isn't such a drastic change in rpm/torque when it shifts.

Thank's for chiming in brian . If thats the case maybe i'll just get a single speed car. It's looking like the ofna gtp is the leading canadit . since my friends kyosho has a 2 speed that i would have to lock in gear . I can get a really good price on the gtp . Do you agree with the MEDUSA motor recomended eairler in this thread . This would be run on 4s .

60 - 2000kv should be good...
