Outstanding, Iam new to this forum and just getting back into RC, I build dragbike engines as a hobby and have been doing everything in my shop for years with the exception of crankwork, porting ,flow testing ,seat and guide installation, custom machine work,etc. my first puchase was a losi 8 rtr which has the mach 427 dynamite powerplant, I am very impressed with this engine performance wise and durability wise, I bought a kyosho str inferno kit off of e-bay for 400.00 nib and was wondering about the axial 28 rr for this application I know there are alot of variables but was wondering if anyone else is satisfyed with this engine for a truggy , or has tried this engine in a truggy of this sort, I must say by reading this forum there are some very knowlegable individuals talking about engines and thats why I 'm asking, I am fairly 2 stoke savvy, very good forum!!!!!!!!!
