Status: offline 		Tattoo, Dave McD and myself outlined the definenition of a QHOR crash:
There has to be at lease three pieces come off the plane.
One or more pieces must be outside of a ten foot circle.
If it does not meet these requirements it was just a hard landing!

Status: offline 		I believe I'm gonna scrounge up another servo and use two aileron servos on my next one. I'm also going to mount the servos for the rudder and elevator on the outside of the rail similar to Tattoo's. Anyone experimented with flaperon/spoileron mixing?

Since I already have a piece of 1/4 ply I'm going to make my motor mount out of it. The last one I used 3/8" UHMW poly and it did well till it started to sag. Alittle down thrust helped harrieres but when it drooped to almost 45 degrees I figured it was time to retire that one. It would do one heck of an outside loop.

Status: offline 		I have a question for you guys, my Spa3d does not have a good roll rate, it is not bad for normal flight but for wild snaps and other stuff are too slow. Servo is mounted like the one Tatoo has in the web page with 35 or 40 degrees for each side but my Super Wasp and another fun fly (called Sexy) is a lot faster than this one. Is this normal in this design? are the ailerons flexing?

Any suggestions??

I thing this airplane has very good elevator control so flaperons are not needed, in fact in my first flight with it, I did a Loop really funny I just slow down the plane until it almost falls and then applied full power with full elevator and the airplane almost pivot in its center, also harriers are so easy that you can fly in a harrier attitude and then pull back throttle a little bit and go to an elevator before landing.

This weekend will try to get some more stick time so I can get used to fly backward while in hover.

[/QUOTE]
Hoveralot, Did you install the the 5/32" x 18" music wire in the flute in front of the ailerons as per the drawings? I think your slow roll rate is due to flexing. I had the same problem until I added the music wire. I had built my SPA3D before the plans were finalized and just went by the description given in one of the threads. I was getting some flutter too before I added the wires.

Status: offline 		Hi Joe,

Yes I did install the Music Wire, but probably is that I am too used to have really fast roll rates, Yesterday I installed a larger servo arm so It can create more degrees in the ailerons (45º) but can´t test fly it until weekend (today is Friday ).
Next Sunday I will post again because the first flights where too short so this weekend should give me enough time to get some clues about this matter.

Thanks,

Status: offline 		FYI - I ordered some pushrod material from Central Hobbies. The .156 OD carbon fiber tubes are very reasonably priced, and they will snug fit into the flutes very well and tight (So you can re-use them in another plane - don't glue them in). They are also VERY lightweight, and VERY stiff. This is what I will use in my SPA3d.

Status: offline 		anyone us a 40 LA on these things...I looked through the posts and may have missed it...if it was there...

I have a 40 LA from my Avistar Select...I love that plane but I want to put the engine to use on something else...tight now I am flying the Ultra Stick with a 46 FX on it...I like it but am afraid to get crazy because I don't wanna put it in...with the cheap 40 LA and a $10 plane...no reason to not get wild!!

Let me know if you think that a 40 LA will handle the 40 sized QHOR well...

Also, what do you use to decorate...will monokote stick...I am afraid to put heat on it...also, how about Sharpie permanent markers...I have lots of colors of those...Also, I bought whits corroplast...so any color will show up...should...

Thanks guys!!

-John

Status: offline 		I tried a FP40 and a LA46, on the smaller one, and both were margional on hover power, it may hover, but wont pull out. Id buy a BB motor, alot more power and fun! I put a OS.40sf on it, now its a rocket! I have not tried a .40 on the larger bird yet, I might pull the .75 off to try it.

Status: offline 		Although I havent done it since I have gutterpipe scraps out the yazoo...I have seen at LOWES in the gutterpipe isle that there is all kinds of smaller PVC gutterpipe joiners, connectors, brackets...stuff like that...I'm sure something like that would work fine for horns and back plates. I've also heard of a guy using a plastic electrical box to make them from. In fact, I would be interested in anything besides the gutterpipe that anyone finds that would work...heck...some good thick tupperware might even work

Your 40LA will work fine on a 30" or 32" Qhor or Pqhor with an 11x4 prop. But to get the pulling power from a vertical hover, you're going to want a mouse can pipe.

I would build a smaller one, I have not run the MCPipe on any of my engines yet, but aparently that will wake them up a bit, even on the small one your not going to have good vertical without the MCP.

But it will fly fine.

Status: offline 		I use these..........

When you get the window shades that you can close by turning a control wand and they have little plastic mounts for the bottom of the window frame, most of us don't use them in the windows.

I don't use them because then you have to unhook the shade in order to raise it up.

So...........I save these mounts which are perfect for control horns. Just drill the holes you need. The size is already perfect and most people throw them away.

I also have used aluminum angle and sliced as needed.

Course if you want somthing that can't be killed, you can use an "L" bracket from the hardware store. I have never paid for anything as exotic as that but........... ;-)

If you know anyone with old aluminum roofing that either just installed or is removing it, a one foot piece of that will give you a lifetime of metal to make quick control horns out of.

Still thinking...........hmmmmmmm..

What type of clevises do you use when you use aluminum horns? This sounds interesting! Does the clevis pin or horn wear from vibration? Have you had any problems with radio interfearence?...man how simple it would be to just make horns from the same stick of U channel as the fuselage ...cool idea!

Man...window shade brackets..holy cow, I wonder what one could find by walking up and down the dinky small dorky stuff isle at LOWES...should be all kinds of small angled stuff

Status: offline 		Hi Tattoo

I havn't had any radio interfearence noticed and as far as wear, most of my planes don't last long enough to "wear" out. lol

I use "Z" bends and the plastic "clip" together type of clevises such as that come with the old foamy lazy bee and the Hobbico sky runner. Cheesy but work great.

I have the good ones but I tend to "save" stuff for "someday".

Just like my wife saves "paper" for someday. lol

I have still yet to build a qHOR. i HAVE ALL the stuff just in the process of tearing down my 12'x12' work shop so I can dig down 5 ft and build a .............ready? a 12'x60' !!!!!!!!!!!11

I will have some room to build planes yet!

Funny, I have more coroplast and blucore to build with then I have room to build.
I will solve that little problem this summer.

Just finished gutting out the old shop. and have a temp shop 8'x12' to cram everything into.

The sign shop where I got the Corroplast had all the people very interested in the airplane and showed me this new color changing vinyl and they could cut out a set of flames to go on the wing. Now these colors change from purple to blue to green depending on which way you look at it. It would look SOOOO COOL so I - - - - - - - - - - DID i got them done at $20 a side. That was alomost done for cost because I said I would put their logo on the body but they are going to be AWESOME floating in a hover right in front of you !!

I have a problem...I cannot get any more coro for a while and when I was scoring the three flutes for the fold in the wing (on the .40 QHOR) I accidentally cut all the way through in some places...(probably a total of about 3-4 inches out of the entire 36" wingspan...

Is this piece ruined (as far as being used for a wing) or could I put some good 'ol Duct tape over the crack (whick will form a Duct tape leading edge) and hope that this works??

Let me know what you think from your experience with these things...

-John
