RE: First flight of 50% Spacewalker
Matt, I doubt that Jack has plans to attend the BME IMAC show, but you never know.
Terry, I fly a 1/3 scale Super Decathlon weighing about 35 lbs with a ZDZ80RV. The plane flies really good. Big loops don't require diving first and do not use full throttle. It will go vertical probably 500' before it really starts to slow down. The 80 is turning a Bambula 26x10 at 6000 and using a Bisson Pitts style muffler. With a pipe it would probably do 6300. Based on all of this, if Miguel will keep the weight below 40 lbs, he will have a real winner with the 80 in the nose.
