weightless trimming tip

I've been trimming wings w/o alu tip weights by carefully peeling back and removing the plastic reinforcing piece at the rear wing root, adding a micro amount of UHU Por and moving the attachment point around 1mm outboard to tighten a looser, more slack wing. The Avitron will turn away from the slacker wing in a glide, as that wing has a steeper neg angle [T.E. up more] and the resultingly more fwd-tipped lift vector creates the glide yaw. Of course check that the wing is not TOO tight and that the steering function still works!

Hey there Lee-
I noticed the same thing about the difference the slightest extra wing slack makes. I've made my own swept back wings for one avitron, but I've been swapping wing pairs to fix balance issues for a while now on my factory wings for the other bird I fly. And I've often thought of doing what you've done, especially since I just broke one wing that was part of my last perfectly matching pair. :-(
But I'm not familiar - what is UHU Por??

UHU por is a glue for Styrofoam.

But the range seems to be a lot less than the claimed 100 m ... it is less than 50 mm for sure ...

I wonder if someone else has suffered from reduced range too ???!!

Thanks

Khaled

Super, Khaled! Good to know you could fly and be happy!

Because of its size, I never fly more than 40m away, so I don't know about anything farther. BUT, as I mentioned to the XTIM crew, the maximum reception is approx when the antenna is vertical w.r.t the flight direction [i.e., body normally nose-high, antenna vertical, which means then tilted fwd when the body is level and not in flight].

My main use for them is indoors, in my apt., but any indoor space will work. Did you see this? [Edwin + Marc] >

b.t.w., as I checked to see if the above video was correct, my clever little bird Kiki heard the Avitron sound, instantly repeated it and flew to the computer. So I played the video for him and he watched them chase around. I had just charged up my so very tiny, tiny nano quad [Proto X], was actually ready to fly it before he came over so I asked Kiki if he wanted to fly with it.

Normally he races it diagonally across the room and lands in the corner, as he knows it is dangerous [the four 3cm rotor/props go 30,000 RPM]. But THIS time, although I flew it diagonally across & back for him as usual, seeing that vid, he flew in circles around the room as he has done with the Avitrons.

Obviously he understood what he saw in the video! And just watching the Avitrons made HIM happy too!

Congrats on your Avitron Khaled. :-). It probably goes without saying but I would double check the batteries if you're having range issues. I did have one Avitron v2 with reduced range and it turned out to be defective. I really really hope that is not the case with yours. Best wishes.

I contacted the makers and they had me run a series of tests, several of which it failed. They ended up sending me a replacement body. If you're still having issues I would try to contact customer service. Hopefully they are still taking care of Avitron issues. Best of luck.
