Just to give an update a friend gave me a 16x6 prop and it seems to be the ticket for the 1.20ax.. still has killer top speed thoughand slows down good for landings

guys-put together my replacement wings only trouble is when bolted onto the wing saddle i have a gap between the two wings almost an eighth at the front tapering done to nothing. I thought it was the dowl alingment but they fit in tight I am thinkinking it is just the way the wings are going to fit they are tight, and solid. Just wondering how much of a gap others have between their two wings.

Hmmm. I think I would call HH on that one... Sounds like they put the dowels in the wrong spot. If you're going to join the wings permanently, you could epoxy in a wedge, but if not, I'd be hesitant to use them with a gap.

Post a picture to see more exactly.
If I remember you had the ...series one blue nose on electric? It is a year since then and I do not quite recall.
Those wings are the new style? Maybe you have torework the saddle to get the gap out.

PS. It is any one willing to try my FG 20 converted to Walbro carb and test it on the air.

the wings are the new style. Like I said the dowl alignment was slight off i put a flat on each dowel to make them fit but i still have a gap at the front.

800mZero,

I would find the right size plywood and make a gap filler. Do you have the same size gap on the top of the wing?? Also check the wing tube. When I had my Blue Nose, my tube was a bit to long, that gave me a gap like you have. After I did the mod on the wing tube and the wings was a tight fit, the dowels holes in the fuse was a tad off!! I think that plane was done at the end of the work day!!! The more I see this plane, the more I think I will buy another one, but the Top Flite P-40 Warhawk ARF will come home first!!! Hope this info help!!!

Yup,

this is what Ithought that you talking about the gap. I had the same thing ...even worst. Ithink that the plastic tubes inside the wing are not in place perfect in position.
Take tube out and see how it fits on the fuse.I dig out the pics from my plane. to see befort and after.
Itook the tube, inserted in one wing, mark where it comes out from the wing and then on that area Iapply a little hammer TLC like 1/2" on both sides of the mark.
Or you can try to slightly bend the tube .

Thanks
Adrian

All you folks over powering......get ready to see this. Mine fell off at approach at about two feet off the deck so the plane survived.

SR2112,

All I can say is " Nice Save "!!! I am glad that you was landing. Just think if this had happed when you was doing a low high speed pass!! Looking at the picture, it will be a easy fix.
Again, good save!!!

What engine did you have ?

I purchased the H9 Blue Nose and put it together exactly the way they asked...even down to all the JR and Spectrum and Saito products. Plane looks great but is a PIECE OF JUNK!! The front of the plane fell off during the maiden flight landing due to poor design and use of hot glue. I put it back together correctly with tri-stock and epoxy, then lost the plane on the second flight during landing. Yes, I admit I thumped the landing due to using full flaps and it slowed down too much, but does the entire wing need to disintegrate on a rough landing? I think not.

This plane is heavy, and underpowered with a Saito 1.25. I managed to get this plane to weigh 10.5 pounds dry, but it still is too heavy and underpowered. Construction is very poor, the materials are very poor, and all the glue joints are hot-glued. Unless you can perfectly grease every landing, you are screwed with this plane. The retract mounts are very weak and should be reinforced; which I did and still damaged the plane beyond repair on its second landing.

The worst aspect of this plane is the absurd tail wheel setup. Poorly concieved, poorly engineered and barely works. You will have to re-adjust it after every flight and be very careful during taxing to take-off.

H9 had a good idea with the scale details of this plane, but they fell way short on fit and finish. The printed covering did not line up in spots, the exhaust stacks look infantile, and the retracts are not scale due to the absence of offset axles. I added custom scale exhaust shrouds and stacks to upgrade the look of the plane, but the poor fit of the top hatch to the fuselage was a glaring eyesore.

Also, be careful with the covering. The flat finish is by way of a film that covers the Ultracote, and it will come off with the slightest tape adhesive leaving you screwed unless you meticulously peel off the whole section to match....which I had to do when I taped the canopy during assembly.

Bottom line: Go with the Top Flite, even though the H9 looks cooler. Perhaps H9 is correcting the problems on the next run, but buyer beware.

sahill,
I FEEL YOUR PAIN !! I too feel that this plane is poorly constructed. You are right about the tail wheel. I had to re-enforce my tail wheel cause I noticed what crapy construction H9 had done. A tail wheel bracket, balsa wood and some Zpoxy did the job. Also, The landing gear area was re-enforced with fiber glass and Zpoxy. This is the second time I hear of the front of the plane falling off. I will make sure I re-enforce it the wood and zpoxy. Surely this plane is not H9's best quality. Certainly not worth the $319 I paid for it. Mine is yet to get off the ground cause I am not done with it. But honestly, I am scared to try right now.

On another note, I am about to install the carburetor scoop and noticed that the screws they provide are wood screws that go screwed into the wing's wood. How is this possible ? What about when you take the wings off the plane several times, wouldn't those holes get worn out of screwing and unscrewing and eventually not catch well on the wood? Shouldn't these screws be like the screws used to mount the wings to the fuselage which have their blind nuts ?? Did I miss something here ? Some input on this will be greatly appreciated by any one.

RodanAZ

Most have secured the scoop to the wing, and put the wing bolts in from the canopy side. It was discussed early on in the thread.

flyboy0608

Yeah,..I just recently joined the discussion so I missed those threads. But how do you put the bolts in from the canopy it the canopy is sealed ?

RodanAZ

It's in this thread. Basically, you put the blind nuts in the wing, and the bolts go in from the top. Not through the canopy, but under the hatch.

flyboy0608

OF COURSE ! ! ! Sorry, I mis-understood you. I see now how to do it. Thanks I have the blind nuts,..just need two log screws now. Thanks for the help ! ! This was just another screw up bu H9.

I find it very interesting that some people have had great reports with this bird and are still going strong whilst others have issues one after the other. The quality is most definately not up to standard by a long way. Mine is almost complete and I have reinforced where possible and done quite a few of the mods on this thread. Let's see how she goes!

flyboy0608

Can anyone tell me where i find all there thread on this blue nose, I just can't seem to find them.

One thing I learned with H9 birds is that if you don't, at the least, go over every joint you can see with thin CA and thick where needed to fill gaps. You are headed for disaster. I've read thread after thread and I don't think I've read one that hasn't had issues such as this. This plane is heavy, it was designed to be flown in a scale manner. Should it be classed as a 60 size warbird, not in my opinion. 7-9lbs is the usual range for a 60 size bird. You start tipping the scale 10,11,12lbs you are entering the 90-120 size range. Which in turn requires more power, 30-45cc range.

As far as the quality, everyone complained that it was to heavy, so what happened? They cutout the fuse in places for weight reduction. Only other way to achieve this is lighter (weaker) balsa. My advise has always been on all H9 birds, reinforce reinforce reinforce before you start to build. 30 min epoxy, thin and thick CA, brushes, even fiber clothe should be your first part of the build on these before you even open the manual. Spending an evening going over everything could save you an evening trying to salvage parts do to a failure of some sort.

just my 2cents...

Shane;

You said it all!!! All the ARF I buy now will have a 1 to 2 days re-glue job!!! The area that get the best re-glue job, is the high stress area, ( ie landing gear, firewall, and the wings hold down area. Back in the days, kits was king. You go to your local hobby shop, buy the plane you want. Take that big box home, put it on your workshop table, open it up to see a box of wood and a set of plans, and 5 months later you have a plane to cover, but you know the plane is built right. While ARF cut down on the build time and get you in the air fast, you still need to go over the high stress area and re-glue!!
Just my 2 cents!!!

This is definitely true with the new Hangar 9 ARFs , I have the Bluenose and the Denight and they dont compare in wood quality or durability to their older models. I did 300 plus flights on my old H9 P-40 and never needed a drop of epoxy.
Again Topflite ARFs are lightyears ahead of the new H9 models . You can easily tell that Topflite have applied their long experience in qualty kit design to their new ARFs . I can speak for their P-51 60 and the new P-40 which I'm currently assembling.
They may not be 100% kit quality but certainly way superior to my H9 models. In fact given the choice between a TF kit or their ARF I would choose the later because of the reduced weight . You simply cannot go wronge with TF.

Speedracer2112

It had a Saito FG-20. That engine STINKS!!! It literally vibrated the plane apart. The prop was perfetly balanced. I lost all hope on this plane. Its too heavy. She just sits there. No amunt of glue could hold it together.

No more H9 for me. Junk Junk Junk Junk!!!

Managed to save some weight by using 2 cell lipos for the receiver battery instead of the heavy 3300mah NIMH (weighs over 300 grams!) She comes to app 4.9 kilograms which isnt bad but not in the range stated in the manual!

Hello guys,..as some of you may recall, about a month ago I was just starting my build of the H9 Blue Nose. I know that this plane was designed for a 4ST and all you who are scale fans wold probably hate me for this but,.....I just had to cut down on money and 4 strokes can be expensive in my books. I was originally installing a 2ST 1.20 AX sideways and tried very hard to make it work. I even ordered a side mounted pitts muffler that went with this engine. That muffler ended up being the overall problem. It was too big to fit inside the cowl. I would have had to cut the cowl too much to make it fit. I already had to cut the cowl in order for the cylinder head to stick out, I just did not want to tear up the cowl any more. So I went for the smaller and surprisingly more expensive 2ST 95AX, which should be great power to pull this plane around. I mounted that one on its side and installed a smaller pitts muffler and the muffler fits perfectly inside the cowl with the pipes sticking out the bottom. After re-enforcing the tail wheel section with a tail wheel bracket ( shame on H9 for this sloppy build on this tail wheel ), the firewall with some epoxy, and in my opinion doing a better job than H9 did on securing the scoop to the bottom of the plane with blind nuts and a couple of screws, I finally finished her today. I have not yet though broken in the engine. That will come this week and then the maiden flight. I just hope that I can avoid any other problems I have hard you guys talk on the threads. Anyway, I have posted some pics of her for you guys to view. Would like to know your opinions on how she looks. She may not be perfect to scale because of the 2ST engine, but I was happy the way she turned out. Enjoy ! ! ! !
