Quick and accurate – RC Heli Calc Review

Wow. This app is easy to use, and very accurate. It was cool watching the gear ratio and head speed update as I was moving the slider. I just wanted to see what the effect of installing a 13 tooth pinion was, but ended up spending 20 minutes checking out all of the possible combinations. This app is a must have!
