Hi,
I am also running a FLM conversion but using a feigao 8XL & BK9920.
1) Motor - I think a Neu 1515 motor should be enough for racing.
2) In addition, I had LST shocks but could never tune them properly. Finally, I switched to Jammin' Super Big Bores on FLM towers & I was pretty happy with the results. Note that this is for running on a track though
3) Shock towers - I use FLM towers. I got a pleasant surprise recently when I bought a pair of FLM towers. One of them have holes for mounting a wing already machined onto the tower. The holes are suitable for mounting a HB lightning wing stay. Ask for it :
4) esc - MMM is the way to go. I will be testing mine this weekend
5) Body - Losi 8ight T body fits well. It's narrow & long.
6) Suspension - go for the racing suspension conversion :
7) dog bones - go for CVDs all round
8) tranny - I think 2 speed is more than enough. Personally, if I can go fro single speed would be even better for going round a track
Good luck & show lots of pics !
Regards,
Joe Ling
