Shmo,
IMHO, adding wingtips or changing the fin isn't worth the trouble.
Originally I was going to put lightening holes in my Predator, but forgot to cut them out before covering it. In hindsight, I'm glad they aren't cut out because I'm not so sure it would have survived through several midairs, and one radio failure.
I would definitely use Ultra cote instead of Econokote.
I use a 6oz tank with an OS 40FP. That gives enough time to get airborne, fly 5 minutes of combat, and still have enough fuel to setup the landing approach. Besides, there's no rule that says you can't use a partially full 6oz tank.......but it sure it tough to put 6oz in a 4oz tank!
Hitech 85MG or 225MG? No experience with either one so I won't guess. But avoid using sloppy servos or your chances of having elevon flutter will go way up! I used Futaba S-148 servos with the LDM ball bearing conversion on the elevons. So far, no flutter....even during full power hot pursuit dives.
This was my first experience with using Goop, and I was impressed. I would recommend giving it a try. In my area, K-Mart has it.
Thicker plastic for home plate needed? Nope. It works perfectly as designed.
Magnum 28 or MVVS 26 combat? Can't help you here. I opted for an OS 40FP instead.
Opinions? The Predator is an extremely rugged combat design that flys well. But I deviated from the instructions and moved my balance point back to 8 5/8" from the hingeline, and added 2 degrees of downthrust to the engine to improve the flying characteristics.
