My 60 Su-do-khoi came out at 7lbs even with a .91FX and Mac's tuned pipe. Performance was incredible!! NO wing rock during elevators or Harriers. Very controllable waterfalls ON THE DECK! unfortunately on about the 1000th violent blender I folded the wooden dowel wing spar and it met its demise. What a shame. I really loved this bird. With a 15x6 Pro Zinger on the piped .91FX this bird screamed out of hovers. Saito 1.20 should be a great choice as well. I saved quite a lot of weight by swiss-cheesing those heavy landing gears. Also. I didn't sheet the fuselage, but rather capstripped all of the formers and longerons. A lot of weight was saved with no sacrifice in strength or rigidity. I miss her!
