Robs Wicked Wing Remix

rob.thomson · May 23, 2014, 03:36:46 PM

Been meaning to do this for a while...

Its a 1.5m wicked wing slope soarer.

I have popped a motor on board, and nodded the fins + pushing them way way back to eliminate yaw rock.

It will carry a 2200mah pack with a 900kv motor, so should get me 15 to 20 mins of fun :)

Looks nice :) Are the booms for the fins not going to flex easily ?

Nope.

6mm carbon tube.

They are mounts onto a large ply plate I buried into the foam.

Looks Very Nice! Looking forward to seeing how it goes!

Looks good that, hope it works - won't they vibrate a bit in prop wash though?

Suppose it's one of those DIY things that you never know if it'll work until you try :D

Shouldn't be an issue.The prop is about 5cm from them.

If you see the pictures, the rods are quite secure.

Even if it does vibrate - don't think it will be any impact on flight as no control surface on them!

Rob, what's the advantage of boom tails over vertical wing stabilizers?

rob.thomson · May 23, 2014, 06:33:35 PM

Gets then well behind the cog.

Result is theoretically less wing rock.

It also means that discus launching it will be easier.

I would suspect that because the wing yaws around the cofg, as the wings are far back any yaw is amplified at the rear stabs hence presumably they would reduce the amount of yaw as they are more "sensitive" to it that's my theory ;)

More or less correct.

They have in effect more leverage!

that's the description I was aiming for :)

Control surfaces installed....

Most electrics now in place.

Once my servos arrive - I can wire in and cover the beast!

Looking really good. If C.G is correct with the battery there then its sure one up on the likes of the Venturi! Must be quite light too..? Should be quite floaty!

Those elevons are massive, must need only a tinnnnny amount of movement for control
