Yep it's a good technique.
Big engines aren't any difference than small engines...they just kick butt more... so watch your fingers ie, don't flick the prop...flick the spinner.
Moki's, by the way need a lot of running in...rich!
We're talking 5 hours at least...on a stand with cool down breaks every 5 mins. Fuel? Lots of Castor... No need for anything more than 5% nitro as it doesn't do anything accept make 'em run bad!
You'll find out.
Fine engine by the way.
