Regal fills the bill for me. Just a great model. Thankyou.

Is the consensus on the KF step that it works equally well on top or bottom?

.062 piano wire. I don't recommend using a smaller diameter for the gear. If one wanted to save a bit of weight, they could use 2mm carbon fiber like the Infineon uses.

I haven't put a step-on-the-bottom KF wing in a plane yet, so I won't say that I know for sure. Since this Regal wing has no dihedral, and it flies very well inverted with minimal down elevator, I can see no reason that a step on the bottom wouldn't work just as good. When rolling the Regal inverted, we have not experienced any increased lift or drag penalty that had been reported on some other KF threads. Our experience is that it flies very similar a symmetrical airfoil, but has some GREAT slow speed characteristics as well.

Hope this helped.

Hmm maybe i'll look at the CF for the control rods then, thanks.

Ah this is driving me crazy, I want to build it now! I almost went out and got the blucore on my lunch break, then I was like wait, I don't have a motor or anything... why? lol

Well I couldn't control myself. I just bought a pack of 50' of bluecore for $32, and I'm gonna work on getting stuff cut out tonight . What can I say, I'm weak

Video - My Experimental Stepped Fuselage Regal

Well folks, I finally finished assembly of a modified fuselage design for the Regal, and got a maiden flight in tonight. The modification is the addition of fuselage steps at the same point as the wing steps. I'm interested to see if there is any significant reduction in drag, or any increased lift during knife edge flight. I had to make a slight profile change to the fuselage due to where the step on the wing is located. While I was at it, I tweaked the front end a bit, and copied the Infineon's attachment method of the rudder. I doubt anyone will want to build this version of the Regal, but I can make the plans available if I'm wrong.

Before you look at the video, please remember that I'm NOT by any means a 3D pilot. I just like to play around with sporty good flying aerobatic airplanes. The second thing to remember is that this is a maiden flight. I only flew for about 7 min., and the video is nearly 5 minutes long, so there isn't much cut out.


I'm very pleased with this plane. It flies like the original Regal, so what's not to like? I won't be able to really tell if the stepped fuselage creates much of an impact on the flight characteristics until I can get together with my son (30V2). Then we'll each be able to fly both planes and evaluate the stepped fuselage vs. standard fuselage.

Hope you enjoy the video and pictures. Now I need to get some paint on the plane!

Great! I look forward to hearing more about how it goes.

Excellent Kaos. Dick Kline and I talked at length about the addition of fuselage steps for the purpose of generating lift during knife edge flight. Please keep us posted on your conclusions. Great airplane my friend!

Wow! I'm impressed. An excellent video of an excellent aircraft. My biggest kudos to you, The Regal is an EXCELLENT aircraft. Seriously, accolades pale. That is one of the smoothest aerobatic planes I've ever seen. I love the high alfa pass and th KFm parachute maneuver. The low speed capability with the KFm wing is outstanding too. Certainly puts a Formosa to shame.

Well done Rich,

Tony

Thanks Tony. After the flight I realized that I didn't try any Harrier flying for the video. That really shows off the forgiving slow speed flight well. Oh well, next time maybe.

Things are looking great, Trumpet. Since you seem to be in the fast lane working on this plane, some foamsafe CA and a bottle of kicker (accelerator) will have you flying in no time.

Thanks! Yeah I'm just trying to get the body done so I can spend the week actually doing something productive while waiting for my electronics to get in.

Do you think hobby lobby or walmart would have Foamsafe CA? (I hope I hope I hope ). If not I'll have to order some and wait for it to come in along with my electronics.
