tested my 21.5 last night in my f1. my novak im running a 3.93 fdr. so i dropped in the trackstar and dropped the ratio to 3.03 since it has a little more kv. same speed as the novak on the straight but alot more get up and go on the infield. timing at max.. for the main i decided to go back to the 3.93 ratio and that was a mistake. i lost the snappiness on the infield and the straight it didnt accelerate as well. temps after the 6 min run were 130 max. next race ill drop back to the 3.03 ratio and see how it goes. if i lose a tad on the straight its ok. ide rather be able to make it up on the infield where the car really shines.
my first impression of the track star motors is 2 thumbs up! very impressed at the power and consistency even after the normal heat buildup. now if we can get the hobbyking guys to get them into 3 stores then we can get em roar approved! please guys please!
