Purchased the 70 back in March, Installed it on a Pilot 31% Edge 540, ran 2 tanks through before the first flight (proper tuning).All in all this engine is so far quite impressive, powerful and starting better after every tank full! I personally wouldn¡¯t hesitate to purchase another in the future, and would recommend these line of engines to anyone.

My 3rd 70T. Smooth running, low idle, excellent engine.

This engine is awesome, super smooth, idles down to 1200 reliably with excellent top end power. It’s in it’s 3rd airframe now, currently installed in a Skywing 91″ ARS300, it’s a perfect match with JMB Y headers going into a 3W L80 cannister. I’m currently using a 24×9 Mejlic Evo, with is thicker and more load than the non evo or the Falcon version of the prop. But it still spins up static north of 6650 rpm.
