check your radio settings, then try a different servo. those Ace servo's from Thunder Tiger are pretty hefty, that version at 200oz of torque and .11 sec transit time is no slouch. I'm sure Thunder Tiger would service it for you it needed.

I wish I had one of those.. their nice!

but then again, Thunder Tiger is a great product.. Im almost done building my second S3, will have pics coming soon, but not in this thread... wish they would come out with another race bred 1/8 scale, something of quality like the Ssssserpent!

AND, I just got my Thunder Tiger .21 pro engine back today from RBMods.net, for some porting work. Rick is an amazing engine modder, and has been modding engines for years, but now mostly concentrates on drag motors!!! http://www.rbmods.net/home.php
