BALSA USA Thunderbug 40
I have one that I purchased built....AWESOME plane. No bad habits and a good clean flyer. It was built using two servos one in each wing panel and is the way to go......I think the plans call out for one in the center with torque rods.....not nearly as good. Sullivan golden rods were used for pushrods and worked wonderfully. I power ours (my son and I) with a ST 40 with an 11-5 prop and have unlimited vertical. Great plane, a real sleeper in the R/C world if you ask me...This guy snaps, spins, horizion to horizion knife edge with limited rudder coupling inverted with just a touch of elevator....yet lands like a trainer
Finish and enjoy this plane !!
