RE: Extra 260 75cc
Just ordered the decal package from BadBradGraphics.com for this plane. I do not know how to post pics but go to his website. I think they are pretty cool and not alot of money for what you get.

RE: Extra 260 75cc
The pilot for the extra must be a 35% pilot.... I received my 40% pilot for my 75cc Yak Friday and it's a little bit bigger than the one in my 75cc Extra...

RE: Extra 260 75cc
Maybe I'm asking the wrong folks about helping me with the decision here whether I should go with this Airframe or the Yak.
I'm ready to buy the Yak after having the 50cc QB Extra. Now after following some online informative threads I am thinking that I would benefit from polling the audience. What are the Pro's and Cons of each?

What type of Flying do you do the most of? The Extra260 is a real clean airplane and my simple mind feels that it's more IMAC style. The YAK for me is more 3D capable (not to say the 260 can't 3D) and in a High-Alpha presentation looks more natural and appears to fly around the prop hub, axil. Your visual preferance also, what do you like, can't go wrong with either.

RE: Extra 260 75cc
Well, I fly 12.5 minutes on a piped DA100, flying IMAC on the same size of tank, and still have about 1/6-1/8 tank left. If your concern is "is it enough", don't be. In fact, I am dropping down to a 25 ounce tank on my plane to reduce the dead weight at take-off. I will still be good for 10 minutes easy...

RE: Extra 260 75cc
I've recently received my Aeroworks Extra 260 75cc and am contemplating a DA-85 engine. I have some questions for the contributors to this excellent discussion forum.
1) Is there any danger the airplane will be overpowered with the DA-85? The recent MAN review of the DA-85 claimed an ouput of 9+ hp. Symptoms of overpower are a) hovering at 1/4 throttle, or b) fast landings in spite of low idle. I've heard that hovering at low power settings can be dangerous because the engine is more likely to quit if not set up perfectly.
2) What is a good canister muffler for the 260/DA-85 combination (assumes I'm going ahead with this selection)?
Sincerely,
Bruno aka FLyingB

RE: Extra 260 75cc
I doubt it will be over powered enough to cause a flame out dou to idle hovers but if you like you can run a 3 blade prop that will absorb some power and you can run at a higher throttle setting for the power to hover.

I went with the KS95 cannister, since it is lighter than the MTW 110, and the boys at DA claim it adds power over the MTW. It is also very quiet.

RE: Extra 260 75cc
Tell us where the ks setup hits the pipe or comes on the pipe. A lot of people care about a clean smoth power transition and any tuned pipe will have a hitch somewhere. Best case will have it come on the pipe after or before rolling harrier power setting.

RE: Extra 260 75cc
Guys!
My decision to buy this airframe is based on my engine/can combo. I have a ZDZ Super 80 with a JMB TR80 can and wrap around header. This can measures 83mm in diameter. I realize the factory can mounts won't work as they are about 77mm but what I need to find out is if the can tunnel itself will allow for the 83mm diameter. Also, this set-up is a little longer as the wrap around header has a very smooth transition. From Sparkplug to back of canister measures approx. 24". Can someone confirm whether this set-up will work?
Cheers,
Lyle

RE: Extra 260 75cc
With that setup, you still have about 2" until you hit the next former in the fuse. The tunnel itself is 85mm, but if you remove the top piece of balsa you gain another 4-5. I would say that the only thing that might prevent it from working is if the header doesn't have the perfect drop, allowing it to center perfectly in the tunnel, but even that can be manipulated...I'd say go for it so long as you have a little know-how, or know someone that does[8D]

RE: Extra 260 75cc
I just weighed everything needed for the can installation, including mounts. it totals 18.5 ounces, so it's about 6 ounces more than a Slimline. However, I dropped 3.5 ounces on the motor mount by making myself a lighter one and using titanium bolts, and another 2.5 ounces by removing the tunnel cover and parts of the tunnel that really aren't necessary, so it's a wash in my case

As a past plans builder, I'm not opposed to making some minor mods but want an ARF to be an ARF.
I'm goin' for it!

RE: Extra 260 75cc
You will definitely be over-powered, but It won't be dangerous. MAN put that very engine in this very plane and will be doing a review of it. So long as the idle is low and reliable, landing speed will not be affected. What affects the landing speed is the weight of the plane and the ability of the pilot.

RE: Extra 260 75cc
Hello to all. Just finished my 260 today. Check this out I put a evolution 58 for power.CRAZY AINT I!!! I have the same engine on a 33% SD YAK54 weight came in at 20 1/2 pounds and it hovers at half throttle and has unlimited pull out. I have a viedo on MUSICCITYAVIATORS web site check it out. I wonder if will fly the 260, I would be happy if it just flew IMAC. if not I will put the DA 85 on it. Question for anyone that knows,if the manual says balance at 3" at the wing tip what would it be at on the inside?Because I have no one to help me balance it the other way. Thanks GOD BLESS

RE: Extra 260 75cc
The plane will fly controllably with the CG anywhere along the diameter of the wing tube. So balance it at about the center of the wingtube and adjust from there as needed.
If you go full carbon and lightweight engine standoffs, I don't see why you couldn't get it at 20-21 pounds with that 58.
