BFG 6 foot twin rotor foamy VIDEO

[MichaelConnally]

Hello all,
I built a twirl style AG for larger indoor events and low wind outdoor flying. I call it the BFG (Big Friggin Gyro).

Total span is 6ft, and flying weight is currently 19.5 ounces though that will decrease a little shortly with the addition of larger and lighter wheels. I will also probably shorten the nose a bit and rework the fuselage shape slightly.

Take a look and these videos and please let me know which one you prefer and why.

That's pretty cool, I've never seen one fly in person, sure would like too.

OMG!!!!! :eek: :eek: :eek:

The 2nd one for stopped rotors!

Way cool! :cool:

Thanks guys.
I knew you'd like it Gary.

Both those videos were taken with a hat cam... makes you look like an idiot, but it sure does work well.

Mike. Nice job on the large twin. Sorry I can't see the video (I am still on dial-up) but the two still photos are great. I built a 150% Twirl from 6mm depron and it flies great on a hacker clone. Maybe I can download your videos if I leave it go all night!

Let me know if you can't dload them. I'll make a dialup version

Bfg1med is better because it is a few seconds shorter.

ad it seems like it has more close ups.

I like the Second one. It has a more "whimisical tone" that better fits the subject. You do more aerobatics and provide some info on screen.

I'm a tried and true hair bander but the music just doesn't "fit" in the first video. I ended up turning it way down so I could concentrate on the very cool gyro.

Are you going to do a build thread???

Mike,
I really enjoyed those videos and the music..looks like are having way too much fun ;) ..she sure is a floater, have you tried it indoors yet?

Great work

Regards Rich

[chem teacher2]

could you give us some sizes
fus length
rotor width and length
rotor thickness

i think that i would like to build one

Pretty cool video. liked the part when both rotors stopped! :eek: Plans available?

[MichaelConnally]

Thanks guys!

Mike,
No build thread... didn't take any pics during the process.

Rich,
The maiden flight was in a single court gym. It was a little tight, but not bad. It was plenty slow enough, but it made the guys nervous that were flying the 5oz 3D planes :)

Tom,
No problem...
overall length not including the rotors = 51"
blade width = 3.5"
rotors = 35"
rotors are made om 6mm depron with a 5mm flat carbon leading edge

Mike,
no plans are planned ;)

[MichaelConnally]

Forgot to mention.... I worked on it some more today.
I angled the gear a bit farther forward and made some new wheels from scratch. They are much larger and a bit lighter.
I added a way to easily change the incidence of the rotors... not in flight, but very quickly on the ground. I mainly did this so I can slow it down indoors. You can see it in the pic below.

Great flight, Mike !! Slow flight and floating down safely are what autogyros are all about....Charlie A.

Thanks!

Michael,
You've gotta rough out some plans for that aircraft! It's too cool to keep to yourself. Great work on it in any event.

Thanks mike. Plans aren't really needed... just take the twirl plans and scale them to whatever size you want and don't put the wings on :) ...besides... if I drew plans nobody would be able to read them anyway ;)

Mike,

I always liked the way my Twirl flies. Your 6 footer is amazing. I particularly like the incidence angle changer. Can you tell me what angle range you are able to set?

Mike,

That looks great. I was going to build a Twirl, but I'm going to tackle this instead. What motor do you recommend? I'm new to the brushless motor stuff.

Thanks,
Bruce
