This is the UCTKAM that needs the rod I'm talking about - this doesn't surprise me. The Profi is out of the box ready to go fast.
OK.....that makes much better sense to me..!
LD....I'd like to maiden it over 4 foot tall grass in July instead of cold, swampy fields, but I don't want to wait that long. 4 foot tall grass WILL save crappy launches with planes this small. I've lost count of the times I've retrieved 1/2 A planes that landed on the tall grass with the engine still running.
Before tossing this one for the first time, I might work out a plan to start out with increased fin area, then gradually subtract area until I [hopefully] work my way back to the original outline.
I'm pretty sure this will involve machining different weight spinner nuts out of brass, or aluminum to compensate.
