Well if your looking for just precision, then I say go for the osiris.

It sure isn't. And it flies like its on rails.

LOL! FWIW I was out just a little while ago practicing slow rolls, 4 point rolls, and one roll circles with my 48 Edge. Not exactly what it's designed for but I'm tweaking my low rates and it's not that bad. I can only imagine what a precision airframe would be like. I'm really digging the 3dhs osiris I downloaded for RF6.

No, I won't ship it. Don't ask

Just unbolt the top wing, and voila, a Vyper!

If you want to practice precision go for the 47".

If you get a 48" Super Vyper you will not resist how well it 3D's. The 47" is a line flying machine.

I loved my 47", it taught me a lot.

With these two airplanes its a win win situation!

Most 3dhs planes are designed to have little to no KE coupling at a certain CG. You can adjust CG to get perfect KE and this will also be the prefered CG that the designer chooses. Some really poorly designed airframes will have KE coupling regardless of the CG.

If the plane is tucking towards the gear, it is tail heavy.
If the plane is tucking towards the canopy, it is nose heavy.


This all has to do with elev. trim. For example, a tail heavy plane will want to climb, so you trim in a few clicks of down elevator. Then when you roll to KE, the down trim in the elevator causes the plane to tuck towards the landing gear.


Always try to fix KE coupling with CG. If it gets to the point where CG isn't going to fix the coupling, or if you don't like the way the plane flys at the "preferred" CG then just find the CG you like and use the radio to mix out the coupling.

If the plane is nose heavy and you trim it for level flight you will need to trim in up elevator to keep the nose from dropping. Now when you roll inverted you have the weight of the nose pulling it down and also up elevator pulling it down so it dives while inverted.

Roll knife edge, you are counteracting the heavy nose with rudder so that goes away but the plane is still trimmed with up elevator so it will pull to the canopy.

This is of course ignoring anything in the design or build that might have an effect.
