Very, very nice.

Saw a turbine Euro fly and it had to have the best flight char for having a fun flying plane. I have a Grippen pusher with working conards and it too was fun to fly.

Go Steelers!!

Hi Leonard,

Looking very nice indeed, lovely build.

Out of interest where have you positioned the c of g, I have it at 12% MCA on the little Minifan version which seems to be spot on and that will obviously be my start position on my 90mm version.

Also at my scale of 36" span the scale position of the main gear would be 5" behind the 12% c of g, which is too far back. I am going to position it 3" behind c of g (still a bit rearward) but hopefully rely on the positive "sit" on the ground plus the working canards to pick the nose up.

Reference your canard drives, how about some 1/8th carbon rod?

Cheers
Ron

Even at my 38" span version I think I will be around 12 to 13 percent also. Going with fixed canards though. And I was going with scale location for gear, but you are thinking of bumping your back Ron? For rollout stability?

I went with the CF tubes. Tubes seem to be much stiffer than rods. I used a pc of alum as bushings for each side with liteply. If you find the right sizes of CF and Alum you will have a nice snug fit that you can add some Li greese to reduce the wear of the CF.

Roughed up the CF tubes and used epoxy to attach to canards. Has held up well.

Matt, you are quite right I meant to say carbon tube, it "is" stiffer than rod.

Ron,

Loved your minfan Euro build and watching the midi. Someday I need to build one.

The high alpha ability makes the delta/canard planes fun and easy to fly. Could barely get my grippen to stall and when it did it would just mush the nose over. Needed rudder for the high alpha flying which I added after a few flights.

Lboogie - Are you planning on rudder control? Could use a very small servo in the back. You really only needed it at high alpha. I found the ailerons useless at slow high alpha speeds.
