I am building one now...i'm using a Feigao 380 8L, an ETTI Navy 70 amp ESC, Speedmaster stinger and sm. rudder (both will be cut down) and a pair of PolyRC (Enerland) 2S1P 25C 3300 Lipos (run in Parallel). I am also using the ETTI watercooled motor mount....

Hope that helps out some!

I'm not sure about the race requirements that you are asking about...

I have a build thread started on Offshore Electrics Forum... "Kent's ETTI Oriental Dragon Mono Build". Check it out...
