I have tried drills but they don't seem to turn fast enough. The Milwaukee works for you?
Rex, I tried drills too and was generally disappointed.
The Dynatron works adequately for up to around 40cc give or take. I've started ZDZ40 with mine. I think that compression is the key, meaning, less will allow the engine to turn over. Also making sure it's wet
Early on when my OS33 had only one or two starts, the Dynatron had a little trouble turning it over because the engine has lots of compression and was generally dry. Once I figured out it needed some fuel in there, the Dynatron worked fine.
I run 6s lipo on mine (2 900 ma 3S packs for park fliers, in series, but I think many other ma ratings will work fine. You want voltage to drive the tron)
I agree on the compression. I had a ys 110 that was a bear to start because of it's compression. I have a 3W 55 that has a ton of compression also. Might take a car starter to crank it! Luckily it starts easily by hand.
I just use the starter if the engine is not cooperating or my old shoulder is sore.
