No guess my attitude as being defensive, I am in a hobby that is a ball, so if you want to read some intent into my posts, it one of having fun. The emial writter can supply only the content the reader gets to guess at the intent. So guess the right way :-)
You'll forgive me as I declined to fly the ship upside down;� I don't feel it's necessary.�� I don't think it's necessary for full-sized sailplanes either!
Too often when faced with a lack of valid arguments, the trend is to offer up either the safety card or the full size card in RC Competition Sailplaning.
Notice I didn't write RC Soaring. There's a difference.
Competiton Sailplaning is about completing a task,,,not about soaring. It has nothing to do with having a man inside or being a replica of flying full size sailplanes, or Sunday soaring.
Make the time, hit the spot. Don't make the time, don't hit the spot, don't get the wood, then go soaring. :-)
Why it would be sacreligious to fly a model upside down as part of a regime to diagnois trim and balance doesn't register.
However, the statement above is valid... its not necessary to fly a full size upside down to determine balance, BECAUSE full size has to live within the confines of a pilots safety, so the speed, stability, g force, etc window is pretty small. Models don't have any pilot considerations like that to take into considerations.
RC Contest ships, as the BOT is going to be use for, have the luxury of being able to be tuned up for optimum performance.
Lead is empowered by gravity, elevators are empowered by airspeed. If you have more lead than is needed to maintain the wing, then the elevator has to be trimmed up. When flipped inverted that now counts as down, and gravity can have its way. When right side up, and flown slow..as in thermal turns or stretched skegless landing, the gravity can grab the nose, and yank it toward the ground. The elevator out of authority lets the nose have its way. That makes for hot landings and long slides ;-) and flying with elevator drag.
Again, getting your plane tuned up perfectly is likely NOT to get you another minute of time or another 25 landing points, but it will allow your models tail to be lighter and the over model to be lighter and fly slower. Lighter lift will be able to lift your model's tail and your model in general. All sounds okay to me and worth flipping inverted once or twice :-)
BY the way guys, D.O. and I are pretty good buds :-)
