Hey Swoop,

Any developments with the Swist?

Waiting on the servo covers to arrive before i order the wing servos.
Just want to check which servo will be the best fit.I have one each of a D60,D47 and a Hyperion DS09 to trial fit and see which will suit best.I am hoping i can get the DSO9's to fit as they are a great slop free servo.
Still havnt decided on the motor/prop setup....any ideas?

Kontronik KIRA 480-32 geared 5.2:1 on 5s with the Sawtooth prop! That gets my vote!

You don't need a sawtooth prop, just put an equal size and pitch normal prop on there and somehow get her into the air. When she is going, the normal prop should even be more efficient.

Anyone know the CG for the Swist ?
What about control throws ?

My friend has bought one, and there are no instructions included.

Whats up with the tiny ailerons ?
How do they expect to install a tiny servo in the wing tips of this plane ?
The wing thickness cant be more than 4-5mm deep out there?


My friend was thinking of gluing the ailerons in place, and using the flaps as ailerons instead.

Why are the flaps so far out on the wing anyway ?

I think you are supposed to tape the little ailerons and the big ailerons together so they move in one piece. Only one servo per side is required.

But the aileron does not have the same hinge angle as the flap......so the tape will fail because it is bent/wrinkled.

Tiny ailerons are all you'll need for the high speeds this thing does ;-)

You definitely do not want to combine the surfaces using a single servo.

Best option might be to you reach out to SUSA for set up help from the manufacturer. The've done well over 200mph safely, so no need to be a "test pilot" and re-engineer; stick with what's proven to work and be flutter free.

Good luck,

Eric

Yes, the tape is used to provide some slack for the unequal hinge angle to work. I guess some flex of the ailerons themselves is also part of it.The Avionik D06 has the same thing. This configuration enables the ailerons to be tapered at the end to reduce drag (in theory) during deflection. I have no experience with this system but supposedly it works well for the small control throws in F5D.
If you're going to use the ailerons as brakes with large upwards deflections I suppose just taping the small aileron extensions into place would make more sense. Maybe it's possible to tape down the small ailerons at the wingtips and to tape them together with the main ailerons and still get enough deflection through flexing. I would imagine that to be quite flutter resilient.

Your wing does not have flaps

This one does:

These are referred to as "trilerons". Use a soft tape like blenderm to allow for the hingeline difference. Not only do they reduce drag a little but they reduce stress concentrations where the wingtip tends to break and reduce flutter by binding a little out at the tip where flutter occurs.

Ok what happens if one wants to set up spoilerons with these "trilerons" ... would they be effective airbrakes with this now limited movement/throw?

Trilerons or gigaflaps are nothing new. They have been around for a very long time and the German Go On 7 has them.

Check bottom of page; http://www.f5b.de/fluegel_additions.html

Hell, even my Avionik B1L had them.

Just put two layers of Kapton tape over the cut and you are done.

And spoilerons are still effective?

Sure, but travel is a bit less with this method. If you're concerned about landing get the version with flaps.
