Goirish: I didn't mean to offend you in any way. Since we may be close in age 83 as you said old habits are hard to break. Look at instructions after we screw it up Ha.These PC's really foul me up. Glad to have them though keeps me busy when not flying or repairing. As well as getting to know new modelers all the time. Been doing RC since escapements but hopefully someday will get one to fly (ha). I now have 23 models some of which are 25 years old and have filled many garbage cans with my wrecks over time. Some of us never learn. Glad I haven't though; great hobby, great friends, great way to stay broke, Ha. Oddly only have had 1 foamy just don't get into them. Guess have to be somewhat creative? Hope you enjoy your DX7. Love mine and have not had a problem with it in 2 years. Great feature, model match; keeps me out of trouble.
