I don´t know how this project is working now,but in this particular video,my suggestion would be.Create a space where the tail prop could go down and transition 90 degrees.For that purpose either you create a hollow part so it can tilt or you build a higher tower to be it´s axle.A higher propeller won´t affect the hovering stability and when you move forward,you´have more power and less problems with transitioning back to hovering position. : ) Tadeo Carvalho.
I see 2 problems: -front prop must counter rotate to avoid it from rolling to the right. -the wing is located too far behind. The center of gravity and center of lift must be closer to prevent the nose to drop (tilting the front motors moves the c.o.g. forward)
@plorks445 Thats funny because the landing gear don't get used anymore for the new model, V.3.b !!! fresh from the scratch build section of the pterodactyl squadron's research department division of Erbalite Air. Stay tuned for the next video unavailing the beast!
i just love seeing how much more progress your making. also, how cool is it that other brains are helping you out with their advice to get your VTOL successfully transitioning into that elusive forward flight.
@wildhover Thanks for watching! I know what you 're saying, it's great to have very knowledgeable people interested in this project. I'm happy to just be a part of YouTube and also to give even a small part to the advancement of aviation would be the biggest thing in my little life.
It *looks* like you have too much differential thrust on the motors for conventional take-off and that is making it unstable - can you switch that off (or dial it right down) for take off? And a little dihedral wouldn't hurt, I reckon.
Also, are the blades counter-rotating? And the right way round for stability (i.e. CW on port, CCW on starboard wing)?
@bluefisherking I do have to much diff. thrust but a tail would help a lot more for making it stable. and with the leftover heli controls in the mix (unavoidable) dihedral would help place the extra yaw into roll with a side of stability.
The Front two props rotate and spin just like a V-22 osprey minus the variable pitch blades. that's spitting dirt at the bottom of the nose in FF mode... i think it is opposite what you suggested.
@Erbalite Yes, I am sure a tail would really help too! Yes, looking at pics of the Osprey, I agree, I think that is the opposite of what I said - I don't understand why it would be the opposite of what you would set up on a normal twin to help roll stability... Must be some reason on the real Osprey of course, but I still wonder if at this scale you might be better off the other way round...
@RCSuperPowers I didn't tell you that this is a magic VTOL that only destroys the cheapest things first! I was shocked at what little damage happened from the nose dive.
I was thinking the same thing about the lesser stunt double. I need to change the design, I should use something I know works or test a stunt double but I'm
running out of good weather soon it will be cold and snowy BLAH.

@gloutch all of this is known and accounted for. have you ever built anything close to a tri-rotor?
Erbalite 6 months ago
You just need to add 2 servo and two "ailerons" at the end of the wing ... that's it ...

Keep up the good work. Seams like the landing gear need to be a little wider is all.

And again awesome jobs guys, you really got something working nice.

Great job guys, you really got it!
What I like to do (and might help here) is break the tests up into smaller tests. You might make a cheap-easy-stunt-double for "airplane mode".
Meaning, just slap 2 motors on a flying wing set up of similar dimensions and proportions. Then get THAT to fly.
This way, you save all those mechanics in the VTOL from getting smashed.
Once you get the stunt double dialed in, then transfer the needed tweaks over to the nice one.
Work from STABILITY backwards.
