How do you like it as Choco asks?
I am a Serpent dealer.......so getting the ZX 21 and 12 is a must..............LOL
With 24" of snow in Chicago.....my 21 and 12 are not going to be FIRED up untill April....however, I think those engines will not last too long in my shop cause their PRICE are insanely low and reasonable.
My mechanic will open up the ZX-21 and investigate the possibility of hand MODIFICATION of the Zx-21, but from the Serpent website pictures, he said that ZX-21 is a BARGAIN for 21 engine, just need a real ROAD TEST to verify the engine.
If this engine is not that good....I do not believe SERPENT will carry that....do you think Michael Salven will run a cheapa$$ not too good quality engine on the big time nitro race and expect to WIN...? I don't think so....
P.S....I never thought I will have the time, effort or knowledge to handle 1/8th, but for this ZX-21, I've myself a used Vector NT just to run this engine against those Evolva and 905R.
