Hi!
You should not use 80/20 fuel!!!! The engine can tolerate it but will not be as easy to set as if you used more nitro!
5-15% nitro is imperative to use for good behavior! Enya 3 or OS 8 glowplug are good ones but most warm or medium glow plugs will work!
A suitable tank size is 240cc (8oz) not bigger!!! And mounted according to the "tank-mounting-rule"!
