I wouldn't have nearly that much into it.
I've been an RC guy for about 10 years and have raced on a semi professional (if you'd call it that) circuit. I've raced dirt, flown/own heli's, done the airplane thing, and now I want to get into turbine. Appreciate the concern, but I got this.
WREN motors are not junk, but with any nitro or turbine motor you need to maintenance it often. Jet is only 20 miles from me, but I am not down for spending 5k on their vacuum cleaner.
