Micro V-22

[MIT KID]

I had a pair of Eflite park 150 motors, and a bunch of g-190 gyros sitting in dormant airframes from mothballed projects, so I decided to try and tackle the V-22 on a much smaller scale.

The airframe is 3mm depron with 6mm used for the wing. I'm using 3 g-190's with 2 dionysus mixers (one for diff throttle roll, and one for pitch/yaw). The RTF weight is about 4 oz.

Preliminary hover tests look promising, but I've got a lot of gyro and TX tweaking to do :eek: . As soon as I get a respectable hover I'll post some video.

Beautiful!

Looking forward to the vids.

Nice! Me two.

The only reason I have not gone to micro VTOL is Gyro/mixer weight I would think would Kill-it!

Just a thought. But you might want to consider tilting the part of the wing that is under the prop wash. This could make things more stable as well.

Looks good ,Way to go with depron :) ,, don't worry about the VTOL gyro/ mixer ... mine never had a gyro / mixer in it ,,,until the last one .. You can do all the mixes you need in a good JR 10 X radio or another computer radio that has at least 4 mixes in it and 5 AUX and the gyro's can be added to it as you need them with small cheap rate gyro's ,, you don't want HH for differential motor control as they react to quick and just get the unit to bouncing around .... You need a gyro that when continuously rotated round and round will push the servo arm over and pretty much keep it there as long as you can keep turning the gyro (well until the wires get all tangled up ) :)

Great work MIT KID!
How much does it weigh?

[MIT KID]

Thanks guys. As is the plane weighs about 4 oz, hovers at a 5/8th throttle or so. Power system + servos is 2oz, airframe 1 oz, gyros + wires 1oz. I figure on the next build I could get it below 3 oz, there's a lot of excess wire and I've still got cases on the gyros, rx, and servos.

Swamped with work stuff tonight, should be able to get some video tomorrow evening.

Snuck in a few more hops, it's getting very close to something workable. Although the next airframe is going to have EPP fuse and tails, not looking so pretty after bouncing off a few walls ;)

Any luck making it stable? Any video, even if it's limping along?

[MIT KID]

Had to back burner this one till the weekend. Prepping for a "real" flight test for work on Friday.

Hey just browsing and saw this, awsome. Could you post a list of all the electronics that is in it including servos and any mixing unit.

I've seen some cool stuff on this site, but this one ranks way up there. Please send video and more detail pictures when you get a chance. Do you have a CAD (DXF or other) drawing of the profile you cut out in the foam? I too have some light weight servos & gyros that need a new home.

I see that your using 3 gyros for yaw, pitch, & roll right? or do you have them in some other config? If not, is the yaw really necesary? I build a rotating wing model that didn't need the yaw. Do you intend to add an elevator servo for horizontal flight control in the future?

Thanks for sharing. -Brad

Cool project, are those GWS 5x3 props?

[PieJesu]

They look like 5x3 GWS CW and CCW props to me.

I'm holding some in my hands.
