Thanks for checking in guys. Still in one piece so that's at least some good news.

Gorilla glue is working much better than the hot glue was for holding the motor mounts in place. Now after hovering they stay just as crooked as they were before the flight. I'm very happy with the hover stability now so I've started forward flight testing.

So far I can't get it to go down the runway without tipping over. At high speed it starts to wobble like a penguin and tip over. I think it has to do with the weight of the motors being on the wing tips. If I hit a small bump at high speed the wings act as levers allowing the weight of the motors to torque the light fuselage over. I'll try a lower CG and some other things to see if that helps.

I thought getting it to hover was supposed to be the hard part, not going down the runway.

Never use hot glue to fasten motors, it will melt as soon as the motors gets hot!
Also, never glue motors directly to foam, as foam has almost no structural strenght.

Instead, use some 2-4 mm ply or balsa for a motor mount, and epoxy to glue the motor to it.

Now you tell me about the hot glue melting

I was going to use a ply plate for the motors but didn't like the weight penalty so I went straight Gorilla for now. So far I'm impressed with the strength of foam.

Here's a last hover test before I resume forward flight crash testing.

Thanks. The AwesomSprey is doing well. Found a local park so I've been doing lots of crash testing lately working on the 45 degree flight mode. Hope to have something to show soon.

Forgot to mention that I stripped a servo gear on my last landing/crashing.

Could use a spare plastic gear from a Corona 939 or 929 metal gear servo if anyone has some.

I have three in my functional quad plane but they are hot glued in place so I'd rather not tear up that plane just to get at the precious plastic gear if I can avoid it. HobbyTown near me had no gears that would work for this servo. Took a look at the Osepp servos a Fry's electronics but I can't tell if the gears would work and at 20$ a servo I don't think I'm going to find out.

If the weather is good tomorrow I'll be busting out the camera. Those that wish to repent for their LOL votes should do so now and I may be merciful.

Special shout out to my peeps at the local flying field that have wished me luck with the build or told me that they have been watching its progress. Much appreciated.

Thanks. Big thank you to bhoov128 for sending me his TX and RX. This would not have happened without it.

As for the harrier. That gets built as soon as the defense budget allows it. Congress, A.K.A. mommy, has made some massive budget cuts recently and I need to go see the new Hobbit movie.

Thanks. Got the the conversion to 90 degree motor tilt for forward flight pretty smooth now.

China call me. I have VTOL secrets to sell. Sorry Lockheed, you had your chance.

That flys really nice mate. Looks like you got it dialed in too. Love the vertical take off and landing too.

Edit... I would be frightened to fly with all them light posts about though lol
