It is a very fast motor. In my X10 predator it was a handful, too much power for the track (low grip, medium/large).
I much preferred the 5700 motor, more consistent laps, less "drama" all round.

Default yeah

I would agree with big boss the 5700 is the best off road motor. I run on a very high bite large indoor track and I run the 5700 in my truck and my 4wd. The 7700 motor is more for just insane fast speed runs not a real good race motor.
hope this helps.

I ran the 7700 in my xx4 and it felt great. On my b44 I run a 7.5 and it feels good but not as smooth. By the way my cc has never overheated, i wish i could say the same for my gtb/7.5.

I've run a 7700 and 5700 in my XX4. The 7700 is fun... but the 5700 is more than enough and probably will get you better lap times and cooler equipment.

I switched to the 5700 at the last big race and won't be going back. If you can't resist going for the hot motor, try the 6900 instead of the 7700.

The 5700 is a nice combination of speed and power. The 6900 would more than likely have more power than one could use 99% of the time. When I get my 4wd I will start with the 5700 and if I feel I could use more I will try my 6900.
