What kind of throws are you guys getting on the ailerons? Did any of you do any aileron modifications to increase them?

Hey Turbo, why are you selling your extra?
Did you not like the way it flys?

Well, the stock rudder servo mount broke today, it broke on the sides right where the lightening holes are, I think the only thing holding it together is the little bit of fiberglass on the sides of the wood.

Sooo...

I'm ordering up the AirWild servo tray to fix that problem.

I wouldn't recommend using the stock tray, it seemed to build pretty solid so I thought it would be ok, I haven't really pushed the plane very hard yet either. I got lucky that thing didn't break completely loose in flight. I do quite a bit of knife edge stuff, I like loops and cuban 8's while knife edge and I have two 8711's on the rudder sooo... it's not like I can't see how it broke.

Other than that, I put on some tail weight today, it really helped out the 3d on the plane, pop-ups and hovering are much better than they were, rolling stuff and harriers are much easier, I'm going to install the tray and then move the batteries back to keep the cg where it is now.

Anybody else flying or building this thing?

I am having someone build mine. (I like to fly not build ) Anyway I am using the SWB rudder tray with the pulleys. I flew it in my Edge and really like it.

Camss69 ... do you know where your CG ended up?

Thanks,
Doug

I'm going to figure out the CG exactly where it is now and leave it there,(I don't know where it is right now) I'm guessing right now it's at the aft most recommended range in the manual, I was about 2/3 back of the recommended range before.

I'm going to figure it out this week and I'll post where I am now. I know that today I rolled inverted and it pretty much kept flying straight and level where before it required down elevator to stay level and on an inverted 45 degree up-line it just kept going without climbing or falling, so it should be good to go now.

I'm also ordering one of these deflection gauges so I can set up the throw exactly.

http://www.airwildpilotshop.com/More...product&id=542

I like both the SWB and AirWild stuff, the AirWild tray is slightly cheaper, just as good, and recommended by the field expert so I'm going to give it a try.

I had to build mine myself, that way if I didn't like the way something was done I can just blame myself and it was kind of a pride thing for lack of a better word, I bought it, I'm flying it, of course I built the thing.

The Fuse with all ready to fly equipment in it minus the canopy, wings, and stab, is balanced at 53cm from the tip of the spinner. The weights on the rest of it should be pretty much the same I would think from plane to plane as long as you have two servos in each wing.

I've started the rudder tray conversion, I recieved my airwild try and hardware kit yesterday, I'm going to try to mount it so that the servos are in the same location, with the tiller arm a little further back in the tail. I'm trying to figure out how to mount the tray in the plane, just some rails mounted to the sides of the fuse and then two rails going across the fuse but how do I hold the rails to the side of the fuse while the epoxy is drying? I don't have a gaint clamp....

Thanks for the info. Can't help with the rails but I am sure you will figure something out.

camss69-- In previous composites I used hysol without clamping and have had no problems. I also have the mounted the cross rails that hold the rudder tray directly to the sides with little horse shoes under them without any problems either. On that one I used epoxy and milled fiber glass. Be sure to sand and clean the surface really well.

Thanks, are there local places that carry Hysol? What's it normally used for, can you get it from Home Depot or somewhere similar?

Thanks!

I looked for Hysol here locally and could never find it. I had to order it.

BVM carries it along with a few other giant scale vendors. There a many different types of hysol, they are thioxotropic (sp) meaning they will not run and stay where you put it.
You can accomplish the same thing using milled fiber and epoxy.

I just maidened my Extra 260 today. It´s the Flying Circus color scheme, engine is an EVOLUTION 116GX2 and JR 8411/8611a all around.
Wow, what an airplane. It flies extremely precise, like a perfect pattern plane should do, just some minor coupling for straight KE needed.

Though the engine is around a pound heavier than a DA-100, vertical performance is insane. I´m running a BIELA Carbon 25x12 3-blade turning already 6,600rpm!!!!! Try that with a DA-100[&o][img][/img].

Uli

Awesome looking plane. Would be very interested in your AUW if you could get that.
Thanks,
Doug

It looks great, way better than the pics on Comp-Arf's website. There is a local one being built by a friend of mine in that same color scheme, I can't wait to see it.

Hi Guys,

Ive just ordered one of these in white, (I have my own color scheme in mind) and am going to set it up with a 3W 106 Competition motor. Any one out there done this and has advice to offer?

Thanks

Hello Spat Cracker,

I was originally going to use the same engine, but the cowl gets very skinny towards the front and my DA100 just fits. When I was looking at the 3W 106CS, it looked like it may hit the sides of the cowl due to the extra 1/2" or so in width vs the DA 100.

I would be nice to hear if this combo works. I almost did it, but then I decided to go with a DA 100 since it was a "known good solution".

I too have a white one which should be ready for maiden in a couple weeks. I also went with a DA-100. The main reason is because I am used to the DAs having them in 1 previous plane and my current Aeroworks Extra 260. Just really like them.

Will be very interested in how your 3W does. Keep us informed.

Thanks guys,
I have the 3W CS sitting there needing a home so this is going to be it. A mate of mine is putting a DA85 in his, aparently they go well together also. Il keep you posted, just waiting for the long boat haul from Thailand to NZ.......

If the 3w is wider than the DA you might have to cut a hole for clearance on the left side. I have the engine mounted according to the instructions (I'm using the DA-100) and my ignition cap on the left cylinder rubs against the cowl just barely. Just enough so that it wore through the heat shrink on the ignition wire boot on that side. I'm not sure if the plugs are angled on the 3w like they are on the DA or not.

A friend of mine is just about finished building one with a 3w and I can try and find out if he had clearance issues on the left side or not. His came out heavy at 30lbs but he has a smoke system installed, all JR 8711's in the entire plane, the big Fromeco 5200 batteries instead of the 2600's. I will be interested to see how it flies compared to mine which aside from a carbon wing tube and only running a single servo in the wings is about as light as I could get it.

On another note, I've recently starting adding the mix for knife edge flight. Wow what a difference, I should say that I don't usually add the mix in for my planes, I usually correct for it with the sticks in flight.

I was able to do inverted flat figure eights with the plane on the first try after adding the mix, also knife edge snaps, harriers and hovering were all tremendously easier. Ahh what a difference some tinkering time makes. My next several flights will be finalizing the mixing curves for knife edge correction, adding a throttle-rudder mix, and adding a throttle curve. It can only get better but it's already so good.

Thanks Camss69,
I'll see how it turns out I guess.......still looking forward to the build, maybe I'll cut a cylinder off the 3W!!

HI

My 260 2.6m is too tail heavy, i using 5955tg's all around, DA with stock muffs, 3x Fromeco 2600.

I have all the ignition stuff at the front of the motor dome, I think it would be pretty difficult to get it to balance out at 95-100mm, let me know how you do it, I ended adding about 26oz of lead to get it !!!

Do you know your AUW? How about a spinner, do you have one? That is a lot of lead! Anybody else end up that tail heavy?

That is the same setup I'm running, where is your CG? I actually had to add 3oz of tail weight to get it to fly hands off inverted. My batts and regs are mounted up against the back of the landing gear block inside the fuse. The Rudder setup is at the back of the cockpit, without the tail weight I was at about 112 on the wingtips. Not sure how you ended up so tail heavy.
