Hey Pete C!
I'm having so much fun training my two grandsons. They are both flying my blue stunt plane now with a ST 50V that I welded muffler lugs on and re-timed the engine for stunt and did not lose any power, and it'll pull with any G 51 I've seen. It has the sweetest 2/4 break; it almost breaks like one of my ST G21 46 only a little softer. It sounds so sweet out of a tube muffler. Wish you were here to see my grandsons fly. One just completed a Twister and the other is waiting for his Super Clown to come from Brodak. Both of these planes will fly with LA 40s that I stunt tuned and have a real nice 2/4 break, no run aways. Fuel we're running is Byron 15% bumped to 22% by adding castor and 1 oz of Randy's snake oil. The Twister flew today for the first time, he flew 5 times, loved the plane and the way the engine runs with the 2/4 break. They both want to fly every day, even cutting the girl friend a little short! They'll both be seniors in high school next year and I think they're both addicted to CL flying now!
Your friend-

PS-when are you moving to Farmington?? Could have used your help the last couple of weeks with these grandsons. They have gone through 4 gallons of fuel these 2 1/2 weeks. They are starting engines, taking off; everything they have to by themselves and are flying. Both have flown loops and we only have had 4 crashes (easily repairable).
