Speedactyl, your bird is way bigger than I initially thought! That's was some good flying.

I noticed a lot of wing flexing and was wondering if you thought about putting in some carbon fiber to stiffen things up a bit? There are some simple ways you can do that that Lee showed me...but you may know or have in mind what to do. Again, very good flying!

I use BBQ sticks on this one and I didn't put full span only 60% of it on a soft EPP foam ,
Yes originally I did use a Turnigy 2211 2s motor but since the plane is under power I replace it with a 1300KV BlueWonder 3s Motor which is heavier than usual .since its a rush swap , dint reinforce the wings further and it renders my Ailerons completely useless. so far that flexing did create an roll stability advantage and best of all it didn't flutter.


Duking each other out in the Air is fun , not really combat since we dont want to ruin our creations
more so is it looks like a pretty hyperactive bird

design originally is base on an earlier concept which I made for a flight sim
