Status: offline 		Got one flight in on my QHOR today. Unfortunately, that's all I WANTED to fly it. It could have been the Hitec 225s I was using, but there was almost NO control at higher speeds. The only way I could fly it was a few clicks above idle. At slow speeds though, it was very stable, and didn't seem to have any tendency to stall. I was really nervous about geting it back down in one piece, but the wind picked up a lot and I was able to elevator it down to a pretty smooth landing. Not sure at this point if I'll try it again, but at least it got some funny looks along the flightline!

Status: offline 		Did you do anything different in terms of engine size, deminsions, CG, and especially aileron neutral setting? So far I know of at least 4 that are flying, and I'm getting very positive reports. If something doesn't work for someone, I'd like to figure out why, and how to fix/prevent it. So far, some of the things that can turn a great flying design into a real nightmare to fly are drooping ailerons (#1) Tail heavy (#2) and adverse thrust (upthrust).

Drooping ailerons and tailheavyness are causes for two big trim problems...pitch changes at different throttle settings and pitch uncontrolability (hunting)...the faster you go the worse it gets.

I took the pictures. Dave ( RCU Name rcflyerdave) is holding the models.

I think it had more to do with too weak of servos than anything else. As I said, at slow speeds, it flew really well. Very stable, and easy to control. At higher speeds, rolls were really slow, and there wasn't enough elevator to pull out of a dive. Chop the throttle and it would slow down enough to regain some control. I really don't think there's anything wrong with the design - just my implementation of it!

The only deviations I made were to stretch the wing to 36", chord stayed the same, and used a TT 36. Servos, were the aforementioned Hitec 225s. I may give it another go with some more powerful servos, once I get some freed up. They're all spoken for it other planes right now.

No, I wouldn't think of charging to do it, but it'll be great fun to get some more of these flying around, and a couple of guys have expressed interest in QHOR combat... That should be fun, too...

Man...QHOR combat would be a trip...full speed to 3D...talk about tactics to choose from!!!

Jboy, when desinging airplanes the horizontal stab/elevator should be 18-22 percent of the wing area, and the vertical stab/rudder is half that. But...this plane is sort of in unchartered territory, as the wing is fat with a short span and doesn't follow the rules ...that's why reading about what guys try will be very interesting. I've only flown the one I made the photo essay for, and don't know how far these ideas can go in parameters like tail size, chord, and span. Every one someone builds that's different will be an experiment!

: Be careful - Spads are infectious - once infected, there's no cure except TO BUILD THEM ALL!
:The trouble with that, there are new one's designed every day - you can't catch up or stay even Steven!

That reminds me. I've got to go to Lowes & get some screen and one of those roller thingies.
Hey...................
Might as well get some U-channel, L-channel and gutter pipe while I'm there also. No sense in wasting that expensive gas going back & forth.

: Do you think she'll buy that one?

Status: offline 		Test flew my QHOR today in about 25 mph winds(could not wait).Had to take my Weber 32 redhead inverted off and installed a ST 34 upright with 10/4 APC.I have11 oz. Edge 540 to 60 cc Gas Laser and almost all Morris planes at one time or another to compare to.The plane weighed 3#.It penetraded the wind great,would harrier good(lots of wind),fly inverted as good as upright,easier to build than any plane so far including pvc/coroplast combats,and is a good fun plane to keep in work truck to catch a quick flight here and there.I could not get it to hang on the prop as it was to squirrelly and would fall in all directions.It would not flat spin(only a steep spiral).It is balanced at peak of wing with tail hanging slightly.It is a great design.Will try moving Cg around and testing.Thanks Tattoo for the design..

Status: offline 		Already tried the 2 mil wing, too flimsy. Some stiffening ideas might work. But by the time that's done, you might as well make the wing out of 4 mil. That's exactly what I have done. So far it looks good and is stiff. The wing is 24" x 10"( including 1" ailerons) when I get it finished I will post pics. It will have a .074 Norvell on it and hopefully it will weigh under 1 1/2 lbs. I work with Tatto, and some of his crazy ideas rub off on me at times.

Status: offline 		Thanks for the flight report Dave! Right on! I was able to hover mine longer than I can a pbf...but then i'm still trying to get a handle on that ...I'm hoping the 40 sized with larger control surfaces works out! I'm still not sure how much further the deminsions can go...and am slightly concerned with flutter on the wings at ful speed...so the control surface size is conservitive...I went an inch wider on the rudder and ailerons on the 40 version...

Bubbafly...it's about time you showed up here!!!

Status: offline 		I meant to mention in test report (post 68)of QHOR about my Ciggypack and WOW(shown in post 54).The Ciggypack has lite square tube fuse and 30x28" airfoiled wing.It has OS 46SF with 11/4 APC and weighs 4# even with crazy legs landing gear.It is an absolute blast to fly!It will flat spin and even climb sometimes.It will hang on the prop.harrier,funnel spin(what might be a toilet bowl?) ,tail touch all day long.It does slow, low to the ground 3D better than any plane I have flown including my Giant Knife which was close.It flies level at high speed but occasionally gets squirelly until you slow it down.It is a good knock around plane to play low and slow. The WOW is an18"w X24"L Wings Over Wise Airshow sign that I wanted to try a flat wing.It has an OS 25 FP with 9x5 APC and weighs 3 #.It is fun but very touchy on roll axis due to the narrow wing.(the flutes went that way)The fuse is 1/4" alum. channel from Lowes.They also have 1/2"&3/4". Of the three , I would rate the Ciggypack 10,Tattoo Quor an 8(might be better with a couble " added to wing to get loading down),and my WOW a 6. Dave

What's the folded wing size (or actual size) What is the sizes of the tail feathers. I'm thinking of building one your size for a Saito 56. I'm going to use carbon fiber rods in the wing so to stiffen them.

Status: offline 		Tattoo, I pilfered your idea and assembled a PBF based on this wing. It's 24" span X 28" chord including the 4" elevons. Pine spine, hardwood mounts, GP40 motor and a 6oz tank, standard Hitec flight pack. 1 1/4" tall block at high point of wing, no hole at rear - bolts flat to the spine.

Test flew it Sunday, and it flies a whole lot better than my flat PBF. I'm going to cut it down to 24" square and add a touch of downthrust.

Thanks for the ideas!
