Just finished up my e-8ight using the tekno conversion.. WOW awesome! I've got the MM esc w/ fan and ccBEC (4s config). Gearing is stock spur (48) and 16t on the e-clutch. No temp issues and she runs great! Motor is the Medusa v2 2000kv 60mm.
7,10,3 for diff fluids
50wt w/ Green on front shocks
35wt w/ Black on rear shocks
She runs great and I was owning the nitro's today!
