RE: goldberg matrix
I maidened my Matrix last night. The YS63 yanked it off the ground before halfthrottle and this was still running way rich! Anyway, I took it easy and did just a few rolls and loops and inverted flight all on low rates. I brought it in to check it over, but I ripped the landing gear plate right out. Stupid mistake on part making low rates too low. Went to flair and the stick was already back the whole way. Easily fixed now I'm on my way out to test it again less than 24 hours later. If anyone is using a YS, prepare for it to be tail heavy by just a tad. I stuck the receiver batt up in the nose and it balanced at the recommended 5.5 inch back as a starting point.
