Test flying a Capella in Lithuania. Why is the tail shaking!?

We were able to test fly a capella aircraft in Lithuania. A gentleman just finished building his experimental Capella airplane and was trying to figure out how a few issues with it. Since I was the only one they knew of that had a capella aircraft they reached out from Lithuania to ask for manuals.
While on our trip they reached out again showing that they completed the airplane kit. So we went to go check it out.

Thanks once again for taking us along. It’s great that you may be able to help them out. I’m not sure I would be brave enough to fly with a guy that needed help starting his plane and flying with him in a plane with a known problem(s). You are, at the very least, a brave ambassador. Thanks again, Gary

That could be a tail dragger that somebody converted it to a tri gear. Also the elevator should be square with the underside of the wings. It looks to be maybe square to the top of the wings. Congratulations on your marriage!! I wish you both all the love & luck in the world. A very old builder & drone pilot I known this is old, but maybe the advice can help someone in the future

I would be taking the tail apart and taking a long hard look at all the mounts and proper rigging. That tail or elevator should not shake like it does. Bushing and proper size pin with proper rigging should fix that. Ailerons same thing, it should be more responsive. Enjoyed the video you have a beautiful translator. You are one hell of a lucky man. Have a great week. May God bless you two in all you do.

That was awesome. The guys did a good job finishing the Capella. The engine sounds very strong. The climb out on takeoff is impressive for a 80hp engine. The rudder and horizontal stabilizer oscillation is worrisome but very fixable. First thing I’d check is the control surface gap on all flight controls to rule out flutter.

A few months ago we had just finished building an RV 12 and on its first flight the tail was shaking quite badly nobody could figure it out until a test pilot said the 1/4 inch gap between the wings and the fuselage had not been filled with the rubber strip required, so they taped it closed with duct tape and the tail stop shaking.

@ryanmcgowan3061 2 жыл бұрын

The CG should be plenty forward with two adult-sized children in the front seats, yet the elevators are pulled back pretty good. I wonder what the AOA on the horizontal stabilizers look like at cruise speed? Maybe they are angled a bit too high causing a nose down pitch. If there's enough AOA to cause flow separation, then that explains the buffeting, and also why with flaps down it goes away. As far as the flex from the shaking goes, you could try testing the vertical and horizontal stabilizers with weights and consistent forces like 15 pounds, and measure the deflections of each stabilizer. If they all move together, it's structurally loose at the empennage. If they don't deflect together, it's the tension wires. All the stabilizers do look smaller than I'm used to seeing, especially the vertical stabilizer. Being swept so much, I suspect that torsion could be where the deflection is occurring.

@JonasMarcinko 2 жыл бұрын

I like your ideas. All the comments will be read by the owner and pilot of the Capella in Lithuanian. They should be able to figure it out from all the good comments. Thanks for your input.

@whee8e 2 жыл бұрын

Best part of the video…Sylvia driving a manual. It’s a lost skill in America. The aileron cable looks way loose. If the cable runs up the lift strut you can tighten the wire till is just barely slaps when you flick the stick on the opposite direction. That should get them really close. On the tail the flying wires looked like they were not tension equally. That can definitely be the cause of the shaking. Depending on the flying wire size used on the tail…take a yard stick, a meter stick is probably close enough, and put it’s straight edge against the wire. Then using a pull scale, fishing scale or similar, pull 15lbs on the wire and they should see 3/8” of deflection at the center of the yard stick. 3/8” of deflection is appropriate for 1/4” flying wires. Something less for smaller wires.

Missed you guys, great video! I would be checking gusset supports, the tail is twisting.

@portnuefflyer 2 жыл бұрын

FWIW: My RANS S-7S has statically balanced elevators, lead weights forward of the hinge line. The rigging seemed to be tight enough, and strumming them for equal tone will highlight any tension difference. Could be a burble coming off the cockpit rear taper. Could be a combination of things....he could try some VG's on the hor stab bottom, about 1.5" ahead of the rear spar, using double sided carpet tape before committing to glue. A serious problem for sure. I'd also double check all the basic rigging: is the wing "square" to the fuselage, washout the same etc.

The smoothness of the windshield/ roof / rear window /door/ seams is more critical than people might think. You need laminar flow along the tail, or you will get buffeting. Poor fitting doors could be worth a look.

@golfbravowhiskey8669 2 жыл бұрын

IMO that nose looks off. That would make that prop wash flutter like when you let your back two windows down in a truck going down the road you feel and hear that buffeting. I think that’s what’s hitting the tail and causing that distortion, when you pull the flaps it changes the dynamic to where it does not do it anymore. Anyhow glad to see you flying again

@johnfitzpatrick2469 2 жыл бұрын

Wing fluttering is usually an incorrect cord length of the wing. I'm thinking the stabilisers and elevators would be the same. Measure other similar planes from leading edge to back and compare with that plane. Also there's no "wind" twist in elevators, by sitting a level on each side a eye the top for parallel.
