I've tried the 3.8's from this site and sadly both have failed. Tiny replaced the first one, but they haven't gotten back to me on the second one
Anyone know anything about the "Perfection" 3.8's from toyeast? It says they have won two races that 'appear' to be credible races. Just probing to see if anyone has any experience with these parts...
I've also heard about 3.8 motors burning out. They are probably 10,000 to 20,000 RPM motors purposely designed to be run at current ratings higher than they should get.
