QHOR - 3/14/2003 10:36 AM

Status: online 		Here's my QHOR in a low and slow harrier pass. Engine is a Norvel 25 spinning a Grish 9x4 prop. Weight is 3 lbs, 1 oz with a 5 cell battery for faster servo speed and power (Futaba S-128). Balance point is at 1/2" behind the top fold.

I've been flying my QHOR for a couple of weeks now, and it's proven to be an absolute blast to fly!

I've looped it, (and crashed it), rolled it, (and crashed it), spun it, (and crashed it), flown it fast, (and crashed it), flown it slow, (and crashed it), harriered it, (and crashed it), hovered it, (and crashed it), torque rolled it, (and crashed it), and even reached out and grabbed it out of the air, (and of course, crashed it). Although I've been able to get the QHOR to do flat skidding turns, I still haven't been able to get the QHOR into a true flat spin.

The QHOR has survived everything I've intentionally thrown at it......and more importantly.....everything I've unintentionally thrown at it.

Congratulations Tattoo! Great design!!!

In reality, this is a photo of the QHOR taken just a split second after running out of fuel in a hover.......otherwise known as a "Tail First Geological Exploration". (notice the bone dry tank.)

Status: offline 		Dave, your experience sounds similar to mine (the crashing parts). It's a tough bird. The lg gets hammered though!
How has your fuse held up? After the 15th crash or so, mine bent a bit. I bent it back, but I can tell it will bend easily now.

Status: online 		Frank,
So far, my fuselage rail is holding up just fine......no sign of bending at all.

Now the landing gear is another story. I've lost count of how many times I've had to straighten it back out. But this isn't a design fault.....it's my fault for playing too rough with the QHOR at times.

So far, only two crashes have resulted in any damage.
The first time was when I ran out of fuel in a hover (see post #29 above), and the tail first impact knocked the vertical fin loose, but not off. (The fin was slipped back into position, and the QHOR was flying again within minutes.)

The second time was when I was experimenting with inverted harriers. Somehow I managed to get the wing into a deep inverted stall and the QHOR began falling nearly straight down, but with the fuselage nearly level with the ground. Full power moved the plane forward slightly, but full power couldn't break it out of this deep stall. So the QHOR continued to drop like a brick and hit the ground pretty much flat on it's back, which tore the vertical fin completely off. (Again, the vertical fin was slipped back into position, and the QHOR was flying again within minutes.)

Moral? Don't be afraid to push your QHOR beyond the limits! It can take it!

Have you become a better flier because of not having to worry about destroying your PBF and QHOR? In other words, trying more dare-devil stunts you would try on other planes?
Because of the quickness of the PBF, has it given you more confidence to fly other planes?

IMHO, the answer would be yes. Once you get over the fear of crashing, it gives you the confidence to actually attempt those "dare-devil stunts". But more importantly, flying an indestructible airplane allows you to keep trying those "dare-devil stunts" over and over again without having to repair or replace your airplane between attempts. (example of repair or replace: the beat-up Stickit in my avatar.)


quote:

IMHO, learning to fly a PBF will help improve your reflexes to where other less maneuverable planes will become more relaxing to fly. Plus other equally maneuverable, or more maneuverable planes will be far less intimidating.

And the better you get at simultaneously coordinating all four control functions when flying your PBF (or QHOR), the easier it will be to fly everything else.

Status: offline 		has anyone changed the engine mount design. I have broken my engine mount 2 times out of 3 crashes. Maybe my cutting board material is the problem. Any ideas. Love the plane though more stable than the pbf. will be a good platform for my black widow video system.

Status: offline 		Make sure the cutting board you buy says "Poly" on the lable. I've seen some at Wal-Mart that go by the name "Fiberware" and they are brittle. I believe those are made from second generation plastic (same principle as partical board). I've been using the milky white (almost see through) poly cutting boards on everything from sport planes to combat planes to the QHORs...and I've piledrived some in pretty hard...and have yet to bust a poly engine mount.

My fuselage is the standard 32", using the same exact brand and type of C channel as yours. The only modification I made to your design was to shorten the chord by 1/2" (accidentally), and increase the wingspan by 2" (to account for the loss of wing chord).

All I know is that there's an awful lot of flex in the fuselage forward of the wing. The engine flops all over the place.

Status: offline 		You bet! You will find out that the poly is wierd to cut and if you go too fast it will actually try to melt back together behind the cut!...but the extra effort is well worth it!

mkirsch,
I really don't know how to respond to the flex issues you're having, as we're not experiencing any trouble. It may be possible that what you think is excessive is normal to us. Sure the engine is not as solid as a carbon fiber mount screwed to a plywood box fuselage like a conventional airplane...but in a tail touch flip over to ground nap...a little flex works to your advantage! We've been thrashing these kinds of airplanes all over the place...and it's INCREDABLE what kind of abuse they can take!

Status: offline 		Question,
I went to the local hardware store today, and I couldn't find any channel thats 3/4x 1/2. All I could find was 7/8" by 1/2. the 7/8" being the width of channel. Do you guys think that will be OK. It was either 7/8"x1/2" or 1/2"by 1/2". So I bought the 7/8"

Second, can you tell me what everybody is weighting. Because my FP with hover the snot out of a 3lb PBF, and I am taking that motor off and going to use it on my QHOR.

Status: offline 		Mine with the Norvel .25 weighed in at almost 3 pounds on the nose. The .40 sized version with a TT gp .42 weighs 3 pounds 12.5 ounces

This is the sticker on the channel I use. The 3/4" is the inside diameter...it is actually 7/8" OD!

I am using an os 40 fp plenty of power, but had problems with cuting board/engine mount breaking on crashes. Now using aluminum/honeycomb composite material for engine mount its lighter. flys good with cg 1 inch aft of top wing f

Status: offline 		I just checked my channel it 7/8" O.D. and 3/4" I.D. like Tattoos. I bought me a 72" stick of it at local hardware store for 6.99 + tax. So I am in business. I should start building this thing on Thursday. And if it rains like it suppose to... I should have it build. Because I won't go flying.
I think I got all my parts together.

Status: offline 		Sunday, I flew my rebuilt QHOR; and all I can say is WOW!!!!!!! The first reversion I made was to lessen the wing thickness from 2 1/4" to 3/4" then I shorten the fuse by 7" and that's it. I also built an engine mount out of a poly cutting board rather than a Lexan.
It hovers like a dream; did a tail touch the second flight, it's A LOT more stable than the PBF. With the 40" wing span, it's easier to keep strait in a hover, coupled with a Saito 56 four stroke it hovers at 1/3 throttle, then it blasts out of it with no trouble at all. It flies at a crawl, the first landing I did with it, was into a 10mph wind, it stayed level, no forward movement, and dropped gently down to a landing 50ft. down!!!!!
I set my aileron's so they both were 1/4" lower than level hoping to give it more lift; it still drops (not glides) like a rock! This is a total 3D airplane, it flies of the prop all the time!
The QHOR flies so well I HATE flying my (balsa) Ultra Stick! It is wonderful to fly something that won't break even if you try something daring like a tail touch!!

THANKS TATTOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
