I almost lost the Hellcat two weeks ago. Take off was ok, then doing a circuit turning from down wind, the plane jerked. I didn't thank there were enough wind to cause that. Then while turning at the up wind end, it went out of control. I thought for sure it was going to be a big pile of blue wreckage. I was able to level out, chopped throttle and belly landed in grass. Broke prop and did minor damage to cowl. Turned out the prior owned had fitted it with multi plugs on the wings. Every thing was in the plugs, ailerons, flaps, lights etc. I though this is great, makes assembly much easier. However, just a very little flexing of wing caused connection problems affecting the ailerons. Now individual plugs for flaps and ailerons. So survived that ordeal.

Now I have about 12 flights on the Hellcat. I tried the 21-10 three blade on the DLE 61. There is a noticeable reduction in thrust, less vertical. I put the 22-10 two blade back on. Next flight was fine. The Robert tail wheel had malfunctioned. I had to fabricate new flanges that hold the motor. That is fixed and tail wheel retract is working now. Plan on taking it to the field tomorrow.
