that is an incidence meter

This is harsh , but the only reason she crashed was lack of experiance on your behalf, being a vetran of model flight for about 10 months, and 200 odd flights, I am guilty of the same, but have been fortunate enough to ride the steep learning curve-hence my downer has survived. TO ANYONE CONSIDERING THIS PLANE- IT IS NOT A BEGGINERS OR EVEN AN INTERMEDIATE PLANE at a minimum you need to be able to recognise air speed(not by listening to the engine) & the pre stall point, don't fly on a field that requires you make the runway unless you are a very good pilot. she's a great plane, providing the grass is not up to your chin, just land down or crosswind fast as you like, it works, and is far safer than turning to wind with insuficent air speed. I deadsticked twice on the first days flying (once again inexperiance) and landed crosswind at hell of a speed, she rolled for ever, but was all in one peice.
'
I am sure that the word 'entry or 'begginer' or similar, is on the carton that this bird is packed in -thats all wrong H9

sorry for your loss, I hope you get another-good luck

here's mine awaiting another sortie

I keep seeing dose the engine and wheels supposed to fall off on landing, please be specific, I am thinking of buying this plane.
Thanks

It is a great plane but as others pointed out it is not a slow park flyer. It is designed to fly fast. You are not going to be floating this one in on a landing...it has to be flown in. You just have to look at the size of the elevator compared to an aerobatic plane and you realize it is about precision and control.

If you have any doubts about your ability, just get the smaller Sundowner 50. Should be a whole lot less to worry about with that one.

Remember, this is a relatively heavy and big plane and you need to make absolutely sure your setup is solid. Spend the time to epoxy the landing gear area. Check your engine setup...fuel lines...etc. Check your CG and throws and fly it pretty high until you get the hang of it.

Unlike others here, I went the electric route. Sure it costs more if this is your first big electric, but I have total confidence that I'm not going to have a deadstick. The added bonus...no cleanup and 140+mph.

Best of luck...

can someone translate please

if its about the strengh of the landing gear mounts or the firewall, they are the best I have seen on a ARF

Me also have landed not so easy and bounced pretty good. Bent landing gear a little. You are not going to straighten the landind gear if you do bend it by hand. You will need a vise and some pretty big stuff to bend it back. The firewall stayed intact and did nothing to it when I broke the entire front clip off I have since gotten another and have it ready to fly and have flown it once since but the winds here have not stopped since Jan. other than just a couple days lol. But no problems with landing gear or firewall that i have seen. IF guys are bending them there landing harder than I do lol. Well other than the one landing.

"You are not going to straighten the landind gear if you do bend it by hand."

cut a slot near the end of a 2' long peice of hardwood decking or similar (slot is about 1 inch long across the grain) slip this over the gear as close to the wheel as you can get and using this as a lever she straightens out really easy, if you want to be cautious, use another peice of wood to pull against slipped over the gear down by the fuse. You really do not have to go to the bother of un bolting and using a nasty old vice to straighten it ! nice thing is, the wood does not damage the paint either.

I just finished installing my new MOKI / MARK 2.10 into the sundowner. It was if the plane was made for it. Could not have been any easier to install. Also, it would seem as though the sundowner kit that I have was very well made. I can tell that hangar nine has been listening, and made some changes to the kit. I will be going out of town for a couple weeks, but should have the maiden report when I return.

Cav. the paint did get smudged up putting in a vise but is worked. I tried not unbolting it as that is not real easy. But was afraid I would mess it up at the fuse as u stated. Good idea you have there. I will keep that in mind. When I crashed mine the landing gear held up fine lol. The firewall even thoug it broke right behind it was in excellent shape. It has medal angle behind firewall for strentgh and also on the landing gear it has medal angle. This is just the nicest plane and the looks are incredible. Hanger 9 outdid themselves with this one.
There is I have heard a site that has Sundowners of every color under the rainbow. Maybe a racing site or something. Said they had a pic of them lined up probabaly a 100 of them on the flight line anyone know of this site or one that might resemble it. Thanks.

I'd like to see that shot also.

Here are a few from one of the USRA races

They just are such a good looking plane, I must admit, that after assembling this bird, I spent a fair amount of time standing in my workshop just looking at it !

Last time I flew the downer, I felt that it pitched too easily,once down, I grabbed hold of the horozontal stab and was quite shocked to feel it rotating around the two fixing rods, I have now expoxied the whole thing up. Make sure that you check to see how secure your tailplane is on these rods, you might be suprized !

well worth a look

Well another one bites the dust. Flying great made a pitcure pass down runway at 3/4 throttle. I got to end of runway and went up to turn and make another pass and bang the motor dies. It just quit never missed a beat just died instantly. Well was headed up from not very high and just did not have speed enough to get turned. It was going down fast. Man they slow so quickly when deadsticks occur. Had it level and in great shape for landing. It went down behind some bushes and I could no longer see it. I have never went down to look at what was on the other side of the flying area and had i maybe i could have blind landed. It was about 5ft. further down than the flying area to the ground and when it went down behind weeds I thought it was on the ground and quit flying it. Found out the wheel pants dug in and ripped landing gear, flipped it over and landed upside down. Really not that bad could be fixed but this type plane I don't trust my fixing enough for it. So think I am going to take all the stuff and trade either for a gas motor or a different slower lol plane. I have no problem with flying this plane landings are fine takeoffs a breeze. Just the Saito motor once faulty part from Horizon that they won't stand behind and this time I think the line going to muffler came off. I have not removed cowl yet but looking thru cowl opening I saw the line that hooks to muffler against cowl. Don't know if it came off from impact or caused impact. Anyway time for this hot rod to slow down and go to a light wing load top wing something or another lol.

Today I had an engine cut off. The result: see the pictures. (flipped over on the gras)
By the way this DL50 with a menz 19x14 revolves at the tuned pipe over 8000 rpm and pulls like a truck.

wow if that aint deja vu, i dont know what is. someone else on this thread had broken at the fuse at the exact same spot. On my SD, i had a prop strike from a nose-over on taxiing that was SO LIGHT, it didnt even stall the motor OR break the prop but managed to snap the motor mount box like a twig, ruining the integrity of the entire fuse and forcing me to buy a new stab since they were epoxied. Horizon said it was the result of a crash, i beg to differ. They couldnt do anything for me they said. Wasnt even looking for a freebie, maybe theyd go half or sumthin with me but wouldnt and pretty much told me to piss off and "build one" (motor mount box) but didnt recommend it since the added weight and modified integrity would be dangerous. SOOOOO, my next plane purchase was a Great Planes Revolver, instead of the H9 Corsair Ive been wanting. Great Planes makes some pretty good ARF's i am learning and have treated me like a top tier customer when i contacted them. H9's quality, IMHO, has taken a huge DUMP in the past few years. Seems they are more worried about quantity rather than quality. Just my thoughts and opinions. When my SD flew, man was she pretty. This plane ALWAYS was horrible to taxi on grass with the worst nose over tendency. Sorry guys, i for one despise posters who rip into manufacturers too, but i gotta tell yas, im not impressed with H9 AT All lately. They DO make some of the coolest, neatest, bestest (is that even a word) planes, but quality HAS dropped and customer service, TO ME, has suffered as well. Take it with a grain of salt, and by all means dont let me sway you, but this is how i was "dealt with" lately.

I have lost my engine twice after a pass down the runway, first time (broken header)I landed in a lake with little damage, second time (out of gas) I landed in some shingle and tore the landining gear out, it is well fitted to this model, so will require so fancy repairs.
wow is'nt that just the worst place to have a deadstick, anywere else & she would of been good.

Only flown my sundowner twice now. I agree it has an awful nose-over tendency on grass. I almost have to either gun the throttle with full up elevator for the first 20 feet or give it a slight push to get her rolling and then feed in the power. Other than that it is a great plane. I got her about 300ft and tried some medium speed turns and it will pitch up and rollover on its back so fast it will make your head spin. Has to have the speed to make even a normal rate turn. Other than that it lands beautifully....fast but predictible. As everyone else says....don't let it get slow and you will be ok. I also built the 50 size with an EVO 61NT and it is just the most fun little plane. No bad snap tendencys or anything, I perfer the small sundowner over the large one. The big on is very pretty and impressive in the air, but isn't any faster than the small one. I mostly got the plane for speed, so I feel better flying around $300 than $1000.

Evolution is coming out with the 40cc gass and replacing the 35gt right?
so no more 35cc gas engine???/

It will be interesting to see it Horrizon and H9 then fudge there engine specs for this plane to include the 40cc engine max?

Manufactures are notorius for this.....

Take a look at the H9 Frenzy......
Max 2 stroke is .100.

This would be great for me......
I think that the lightened 40 ZDZ engine would be awsome.....
Light as a 26gt but as powerfull and the 35gt!!!!

Then the GIant scale racing would look promising for me next year!....

Bruno

have you repaired that fuse yet ?? I recon it would be fairly easy once you strip it back ?

Yes I have it repaired. Took me about five hours since everything has smashed and had to be replaced. Was not as easy as it looked like.
Now it looks like new but is much stronger since I've strengthened all the connections and used plywood instead of balsa wood.
This is really a weak point on this plane and has to be checked after a flip over, even on a smooth one.

So my next flight will soon come and will hopefully be without any failure and crashes.
I also checked once again the incidence which was originally 2 degrees difference from one wing to the other. This is also fixed now.

good to hear she's ready to fly. I have not got round to repairing mine yet.
I am about to maiden a zlin 50 with a DL , just a great engine for low bucks, can't see me buying a big glow motor again.

Just got the big Sundowner. I'm using an OS BGX 3500 with a Mejzlik 18/10 prop. The first couple of flights were a real hand full. The recommended throws were pretty much off the wall. The roll rate was like syrup in January with a lot of adverse yaw. It definitely needs ail differential to keep it in a straight line. It also snaps like crazy. But, lets face it, its not a 3D airplane. The roll rate is just about right for wide open racing, but can get you in trouble at slower speeds. The speed is really disappointing. The max static rpm is about 7900-8000 and it will unload in the air, but not a lot. I'm going to try an 18/12. Hopefully, that will improve the speed.

I'm looking for some feedback on realistic speed expectations and/or prop selections. I'm flying at 4300', so performance is going to suffer a little. From all I've read this thing should run like its on fire.

Flew my Sundowner today with no mishaps.. I am using a Saito 180 and today I tried a 5X12 apc prop rather than the 17X8 or 16X8 that I had used before. Wow what a difference it really scoots withthis prop. On landing she comes in real hot eventhough I cut the throtle to idle at about 100 Yards from the start of the runway. She is rock solid on the air and turns on a dime but the rolls are to slow for my likeing.....
