WOW I'm at about 5 1/16 back and its almost to far for me. I can torque roll almost hands off and do lomecevacs on low rates.

Save your self some trouble and replace them with longer screws and a lock nut on the outside. I had mine set up with a DA 50, Menz 22-8 prop, Hi-tec 5945's all around except the throttle and choke. If you use the DA 50 make sure that you use the back position for the rudder servo, that will make the plane much easier to balance. Without a spinner on it it balanced without any added weight. My spinner was not in yet. I would have been able to balance with the spinner, by just moving my receiver back. Hope this helps.

Fortunately mine fell apart while I was adjusting the DA50 carb on the ground. I just red locktited them & have been flying it that way. Now you've got me thinking I should get to the hardware store before I fly again.

I did the same with the hardware on my H9 260 and no problems at all.

For what it is worth their is H-9 Extra 260 thread on Mike McConville's forum (RCUniverse) discussing prop's. Mike recommends nothing larger than a 23" on the 27" Extra. He suggests a 22-8 or 10, 23-8 max.

107 oz servos sounds weak to me on the ailerons.....

[go29kev]

it only called for 80 oz or higher even the jr9411,s only have 82oz(acording to horizon) and that is what the manual said they used.. and i have been flying for 22 years and have never had more than 120 oz on any plane. i am running the same servos on my 1/3 scale warbirds and no problems so i know it was not a servo problem.

hey guys i have had time to inspect the crash damege and i have found that all the glue joints are falling apart and the glue is rolling of the wood like it never tried to bond with the wood and i now am 100% sure that the plane started to come apart at a glue joint causing the flutters and leading to the crash. so everybody needs to check the glue joints and run a little thin ca over all of them u can reach. the glue is very poor and i want to help keep someone from losing a plane like i did...

You are way, way, way overpropping that 45!!! They recommend a 24X8 as the starting prop on the 58, and the 24X10 is what is usually sed on it after break-in. I am sure that 45 is a powerhouse, but not that powerful...

Reza,

I would like to get your opinion on the H9 260. First I plan to buy one and install a DA50 in it. This will be my first gasser. I know the DA50 is a great engine and one I can transfer to other planes, (if necessary). My question to you is since you had the plane with the DA50...do you think the wing loading was a little high. I imagine that landing speeds needed to be a little high...? I have also read in other forums that some have the opinion that the DA50 rattles the airframe and thus weakens it. Thanks in advance.

I used pull-pull and I had to move the batter way back in the fuse, hardly you can get your hand in there but some how I mangaed and strap the battery to one of the formers. I did make 2 posts to strengthen the former and not put too much load on it. Anyway, plane will fly great. You can not find a better deal than the 260. I think it's a great first gaser with a lot to offer! I enjoyed mine for 7 months and flew it many times. Until I put it down but not that bad. I sold it to a club member and now he's enjoying it as much as I did. You'll like that plane. Reza

Hi Tom,
She is a nice plane, with correct engine installed, she will fly like an eagle and huck like a dog...
unfortunately mine was crashed due to change from YS to ST4500, now under construction and ready to fly next week.
Hope yours gonna be success!!

[LookNatU2]

I just bought a H9 260 Extra. My first gasser.. Hope to fly it this w/end

I have read that the DA is to heavy and increases wing loading but I don't understand why. I am running a MOKI 2.1 because I already had one and the engine weighs 2.94 lbs. The DA is 2.94lbs. Seems to me all you are adding for the DA is an ignition battery. While this is extra weight it isn't very much. It would rattle the airframe more but I would imagine if you check everything really well before you go to the Field and after you are done it would be fine.

I have a 20x8 apc w and it pulls the plane very,very well. The glow fuel consumption is not even close to as bad as I thought because I fly below 5/8 throttle all the time.

Be careful when you take the wrinkles out of the covering on the surfaces. They are very easy to warp.

[bodywerks]

You are adding an ignition battery, the ignition unit(not included in their claimed weight), an ignition switch of some sort, and I don't know if your Moki weight includes the muffler, but the DA doesn't. In the ignition alone, you add about 3/4 pound. That is very noticeable when adding it to a plane with only 1100 squares of wing area.

[hillmanr2]

fair enough. I thought the ignition was included in the weight. The Moki weight does not include muffler weight. You could run a smaller tank to loose some weight so if mine weighs in at 13.2 lbs I guess with a DA you would be up to 14lbs.

[Reza]

Sorry to get back with you a little late. I didn't see the post. I think DA50 is a good combo for the plane. However you should be avoiding dual battery set up or anything that makes the plane heavier. I think plane will very well handle the normal vibration of a DA50. It's a good practice to go over the glue joints when you get the plane and check every once in a while. You will have lots of fun with this plane. Roll rate is incredible and knife edges are really awesome. Brian Huff at DA also got one with exact same set up, he likes it too. If you have any questions that I can help, PM me. I sometimes don't see the posts or don't get notification.

Thank you,
Reza
