The motor came back , all fixed and ready to go back into the airplane…and I want to tell you about that. This particular motor is a Scorpion 4025-12 brushless outrunner from Innov8tive Designs. I used the Waco SRE “scale-out” project as my first opportunity to use a Scorpion motor/ESC system. Everythings performs as advertised, but it’s what happened when I bent something that is worth mentioning. As I explained in the last post, the motor came out the loser when I had to land on a bare axle, and the shaft was bent. My first thought was that I’d need a new motor…but…I checked with Lucien Miller at Innov8tive and he said no way, send the motor back to us. I got it back a couple of weeks later with a new shaft and all new bearings. It runs smooth as silk now. Nice surprise…the total price including shipping was only $35.98.

Here’s the Scorpion 4025-12 repaired and back on the airplane. The mount is part of the custom glow-to-electric conversion I did on the ARF model, and the lead weight is a testament to how far electric power for model airplanes has come. The 6S 5300 mAh LiPo pack is TOO LIGHT and I had to add over a pound of weight to get the balance right. Think about that…
The cowl is back in place. I built the dummy engine from a 1/6 scale generic 9-cylinder radial casting from Frank Tiano Enterprises. The center of the crankcase is opened up to clear the motor and permit some airflow around it. In this picture the prop driver shaft and collet as well as the prop and spinner assembly are not mounted yet.
- We are READY TO GO! If you have been following this thread you’ll be pleased to hear that my two part in-depth article on the Sig Waco SRE ARF conversion will appear in upcoming issues of FLY RC Magazine. Watch for it.
