I'd fix the Judge first. You have a pretty strong motor in the AXI. What I'd do is look at the control surfaces on the plane and see how much they move at full stick. If you have a computer radio, you can setup whats called "expo". This will allow you to move the stick
further and the control surface to move in small amounts since most new pilots are "heavy" on the sticks. I'd launch that judge on full throttle. I've seen too many electric pilots launching the plane on half or no throttle. By the time they get to move the throttle stick forward, the plane is skimming the grass. Always launch into the wind and always give it a straight toss. Been doing it this way for years and never had a bad launch...well once, I hit my head once with the wing tip of an FMA Razor flying wing. LOL!!! Boy did she ever drop! Once your Judge is all completely beat up with numerous epoxy patches and packing tape, then get something else.
Yep, expo definetly helps!! I use it on all my glow airplanes.
