I couldn't agree more! IMO these 30%/20 lb. planes are kind of hard to fit an engine to for 3D work. 18 lb. and under, G62 or DA50, BME, ZDZ, etc...... I've got the 3w80XI, and for $600 you can't beat it. Swings a 26x10 with authority.....It is heavier though......that means you have to step up to a 33% bird. Where's it all end. hahaha
