What application and wind are you referring to ?
I helped a friend with his Sonic 4.0 in 12th mod last weekend.
The Sonic is smooth, very smooth, I like that.
But the the LRP 4.0 has more rip, & top end.
This was out of the box with only rollout adjusted
Once we boosted his Tekin RS, the Sonic had plenty of rip, and was a very smooth, efficient, cool running motor.
We didn't try endbell timing adjustments yet.
Can't comment on how it works for 2s racing.
We just run 12th
