Hey guys, I've been a lurker for some time but decided to start seeing what I could come up with some dollar tree foam. my son and I started with a twin boom 30" and a small hobbyking HB2822 motor. lots of fun and we flew it till the booms literally fell off (spectacular crash!)
Next, we moved onto a flying wing,using the Armin arifoil with great success. Biggest problem is getting all the innards pushed forward enough to get the CG where it needs to be. this wing was great and we gotr 30-40 flights on it before it broke up in a high speed dive. Again, we thought ahead and stuffed a very light parachute inside each wing just for this reason. when it came apart, the halves floated gently back to earth ending up in the top of a tree. To this day we've not lost a single piece of electronics equipment.
We are now on our larger wing, 50" wingspan and have it flying well using a sandwich type spar (1" wide balsa strips with blue foam in between as) - this thing is as stiff as a board and has a fantastic airfoil shape! should slow it down a bit and give better slow flight characteristics so we can land it in the yard. Middle section is almost totally hollow, so we can move the electronics around.
No matter how far forward we cram everything, the CG is a battle. the motor is mounted right at the center line right now, firewall at the trailing edge, entire motor hanging off into space. Has anyone had success moving the motor inboard and running the prop in a slot configuration? I'm concerned that we won't be able to get enough thrust this way, but if it will solve the CG problems, I'm game! Right now, with the GoPro on the front, the CG is perfect, but man is it a heavy bird!
Go easy. I've been around the forum, just never had much to post. cheers!
