Status: offline 		Just bought one if the 260's and very confused about power for it. Has anyone actually flown this on this on the OS 160 fx? Did it have enough power? These engines are bullet proof. please email me at Kmay21@aol.com

Status: offline 		I wish I could say I have been flying this plane a lot, but the engine crapped out on me. Took the cylinder off, the ring was broken and the cylinder ruined. Have sent the Evolution 45GX back to Horizon, will see what happens.

I saw the same plane with a ZDZ50NG at the last IMAC contest in Fayettville, and there was no comparison in power -- the ZDZ far outperformed MY 45GX. I am wondering at this point if I had a sour engine to begin with. I've heard reports from others that their 45GX ran better than xxx brand. I will have to see when I get my engine back.

Status: offline 		This may have already been sail earlier in this post, but DO not USE the stock pushrods. I just witnessed the maiden of a Hanger 9 Extra 260 with BME 50 and all stock hardware. 24 seconds into the owner banked around 50 degrees and pulled into a turn. The ailerons started fluttering like crazy and the plane went straight in. Investigation of the video and crash damage indicated that the aileron push rods bent, placing awkward stress on the servo arms and ball links, this caused the (Heavy Duty) servo arms to snapp off. The servos HS 645's did not strip. You could see holes in the bottom of the wing where the detached pushrod was fluttering into the wing.

Status: offline 		Hmmm... got well over 50 flights on mine with the stock hardware. No issues.

Kim, my first dozen or so flights were with the OS 160. It has plenty enough power to fly the model "normally"; but if you're looking for "insane3D/vertical/etc.", forget it.

The plane comes in at 12-13 pounds with the glow engine; some claim much lighter weights, but I'd have to see that on a scale to believe it. Mine now has a BME 50 at 15.5 pounds, and will handle the IMAC Basic and Sportsman sequences with ease. Dunno about the upper classes; there's some vertical snaps in there that need a ton of power.

If you want to sport-fly the model, the 1.60 will be plenty. It wasn't quite enough for IMAC aerobatics, as it ran out out of grunt near the top of big loops. But mine never did run right, which I'm convinced is because of the way I plumbed it (tank on the CG). I tried two types of regulators and damn near pulled out what little hair I have left trying to get it right. I finally said to hell with that and went with the gas engine.

IOW, put the glow tank up in the place provided, right behind the firewall. If I had done that, I'd no doubt still be using the 1.60...

Status: offline 		I have not had any issues with the stock hardware as well.

Flutter is a hard one to diagnose. Did a flutter start and then destroy the linkage, or did the linkage fail and cause the flutter? Just had a club member crash a Sukohi due to flutter, one wing broke off in the air. Examining the remains, BOTH aileron servos had broken loose inside the wing, and actually punched through the covering on top of the wing. One aileron came completely off. What happened first? Who knows?

Which thread? I hope the 4 others weren't all H9 Extras!

This is one bad side-effect of 3D capable planes, the larger surfaces are more prone to flutter, and when the flutter happens it is more likely to be catastrophic.

Status: offline 		Personally, I think a LOT of these flutter problems are modeler-induced; a combination of trying to get the max throw available (very little or no mechanical advantage on the servos), not sealing hinge surfaces, not using enough servo, etc.

The three times I have experienced flutter on my models were all different; one was easy to diagnose (control horn mounted in balsa aileron with no stiffeners; I KNEW better when I was assembling it, but blew it off anyway); the H9 Extra 260 rudder is just built very flimsily, and the top half simply broke off in flight (others have reported this same incident); and the other... who knows? Like Toprudder said, I was unable to determine what occurred first, as the evidence was destroyed.

But the one common denominator in all of these incidents is that the linkages did NOT fail, bend, etc.

The supplied linkages with the H9 Extra model are 4-40 size and plenty heavy-duty enough, IMO. The control horns are attached to 8-32 steel bolts which are threaded through hardwood hard-points. These same pieces, along with the ball li ks, etc., are used on larger (30%-33%)planes with no issues.

My airframe is getting a bit ragged-looking, but seems to be holding up okay; even after getting TOTALLY water-logged a month or so back. A storm blew up and caught us flat-footed. It rained so hard and so long that myself and another modeler were actually stranded and could not leave the field until after ten o-clock that evening; we had to wait for the water to go down across the entrance road.

Trust me when I tell you my airplane was completely soaked; I was pouring water out of the wings when I took it apart after the storm subsided. I worried about this for the two weeks it took to dry out completely; but it flew fine after and seems no worse for wear, except for a few new wrinkles in the covering.

I guess its like someone said earlier in this thread; I've ceased to really care about the model, so it will last forever...

Status: offline 		Steve,
Did you ever get your motor to run on white Gas? Are you coming to the sherman IMAC?

FYI Bradys plane had HS645 metal gear servos, Hinges were installed perfect and the gaps were sealed. He used 100% stock hardware and had the mechanical advantage set up to achieve the maximum throws recomended by the manufacturer.

Status: offline 		Yes, its running fine on the Ozark camper fuel- which is nothing more than white gas. Plenty of power, reliable low end. And NO gasoline stink; I keep the model in the house.

I've got a pretty good rough spot between 1/4 and 1/2 stick, but I think I need to tweak the needles a bit more and do a throttle curve. I'm right at five gallons through it now, so it should be ready to fine-tune. Still learning how to do that (fine-tune a gasser), but I'm getting good flights with no issues, now that the bad plug cap/resistor has been replaced. That was driving me nuts...

Its just been too bloody hot and miserable to get out to the field. We went this past Saturday, early, and by 11:00 we were packing up and getting the heck out of there.

<<...had the mechanical advantage set up to achieve the maximum throws...>>

To get maximum throw, you don't HAVE much mechanical advantage; unless he used huge servo horns. If you go by the manual, your servos/control surfaces will be at 1:1; but there is still plenty of travel left in the surfaces. To get that extra travel, you would have to go beyond 1:1 (i.e., longer servo horns), or lengthen BOTH horns. And from what I've read, the 645s are marginal for a heavy plane (which this one is, relatively speaking). Dunno from experience, but I've seen enough complaints/etc. to stay well away from them.

Not trying to criticize anybody in particular; but it seems like the great majority of folks do just fine with the stock hardware.

Status: offline 		Maiden mine last week and this is the first airframe I have flown that required no trim adjustments. This is the truth and myself and others were also amazed. The plane is powered by a Saito 220 4S swinging a Xoar 19X8 prop and it appears to be a perfect combination for this engine. Sad to say but I'm already considering going to gas due to the high fuel consumption of this engine. One gallon of Byron 20/20 cost me $30 dollars. The Saito 220 4S sounds great and couple this with the smoke trail it provides in flight I'm going to miss it.

I've got a YS 140 in mine, its adequate and super light. I may switch it to a 30-35cc gas, maybe not.

Status: offline 		I hear you re fuel consumption; before I killed it, mine had an OS BGX-1 3500 in it. Better than an ounce a minute...

So what? Its my hobby, and I'd just spend the money on something else. I'm well into getting another one together, and I found one at a hobby shop a few weeks ago that the shop owner had been sitting on for a long time. He was anxious to move it, so the price was outstanding. This has been the best-flying airplane I've owned in 25 years in the hobby. When I eventually kill this new one, I'll put the third one together.

BTW, it does fine with 50cc engines. I had my first one for over five years (250+ flights), and the majority of that was with either a BME 50 or a Brison 3.2. The airframe was still solid right up to the day I planted it while messing around at low altitude. I had just gone back to glow power (and the BGX-1 is enough) due to buying a new vehicle; one of those "cross-over" things. It carries the big model fine; and also the gasoline odor.

Anyway, my new one will have the OS BGX-1. IMO, a 50cc gasoline engine is ideal for this model, because it gives you unlimited vertical with the right prop. The big OS glow engine just isn't quite that strong.

I'm told Horizon is about to (or maybe already has) discontinue this model. That's why I bought a third one to sit on the shop floor for who knows how long.

I maidened an H9 Katana 50 this past week-end that did the same thing. A first for me as well.

I reckon that McConville fellow knows how to design a model, eh?
