Overcoming the dihedral effect of the LE sweep when in KE is easy with a rudder and elevator hanging off the back end. Now, if you can just figure out away to get the same effect with just elevons and rudder.

Which is why the Extreme Flight Outlaw has anhedral. I've built 2 indoor foamy versions that were killed at E-Fest and both worked well. Got too bored with it to do a 3rd. The true delta planform 45 deg didn't hurt either, less sweep = less dihedral effect.

Time to stop messing with it and publish some plans so the rest of us can experiment with it

OK, it is time to get the plans going. Shouldn't be too hard, it is a simple build and I made templates of the fuse/rudder.

Here's a quick video from this evening flying outdoors. Not the best video but I wanted some reference with a BW motor. Tomorrow I'm planning on installing the bigger motor.

Power


I tested the large motor this evening. It would definitely fly faster but at full power and high speed the frame started twisting and it wanted to roll to the left. The motor was probably pulling 200 + watts. I'm going to put the Blue Wonder motor back on, it is a very good fit for this plane flying some 3D stuff.

Planning my fleet for the upcoming indoor season and would love to have one of these. Are you going to publish plans?

I don't know the width of the wing; but from the photo I can see that the width of the wing is not large enough to fight the torque of the prop when it spins powerfully.

Can't wait to see the plans.

Thanks,

This one I have to build! Foam should be here shortly, everything else I have laying around looking for a home.
