Dang, 70 foot wingspan... Bet that is even hard to fit in a van!
JK, I am looking forward to seeing the video! |

RE: Peakmodel Extra 260 25%
Would the peakmodel 26cc gas have the power for 3D on the extra at 5500'?
|
RE: Peakmodel Extra 260 25%
good deal what prop did u do your flight with?

RE: Peakmodel Extra 260 25%
My Extra 260 Setup:
peak 26cc gas engine- APC 17x6 prop 8400 rpm (1200' field altitude) 2 - futaba S3305 ailerons 1 - S3305 ruder (in the tail) 1 - S3305 elevator (in the tail) 2 - 6v 1300 nimh packs (ignition / RX) 1 - Futaba R319DPS receiver 1 - 10 oz dubro fuel tanke ( 14 minutes fly with 10 oz !!!) It has caerbon fiber wing tube (standart) but has aluminum landing gear (would be lighter if carbon fiber), i am very pleased with the model, really neutral flying habits, no wing rock on high alfa, excelente precision and 3D plane. I have not weighted the model yet, but my guess is around 8.5 lbs (3.9 kilos) Jose. |
RE: Peakmodel Extra 260 25%
Looking good Jose. I like both of the colour schemes.
The peak website is a bit light on information so if you can post up your final weight and also wing area that would be great. I took a look at the video of the new extra 260 on peaks website and the peak 26cc doesn't seem to have that much pullout with their setup. General flying looks good but pull out from hover looks kind of slow. How do you think the MVVS (Evolution) 1.6 would go in this bird? Looking at the engine specs on paper, the mvvs has more power for the same complete weight. Cheers, fj |
RE: Peakmodel Extra 260 25%
The peak 26cc engine is hovering the extra 260 about 50% trothle stick, but the pull out is slow, not rocket ship.
I prefered the APC 17x8 prop , it was turning 7800 on that (respectable in my opinion, my ys 140 sport turn the same prop 8400 top), if you would like more reserve power go with the mvvs 26cc, it turns the same prop around 400 RPM more, that is a lot of diference in a hover pull out. When using a smal 26cc gas engine, you must keep it light, use light battery packs, and smal fuel tank, my extra 260 has a 10oz fuel tank, and i can fly 13 minutes with a lot of reserve left. Jose. |
RE: Peakmodel Extra 260 25%
Any idea on the wing area for this plane? I was looking at peak website and saw the Extra + 40cc combo for a reasonable price. I'd be interested in working out the wing loading for this combo?

RE: Peakmodel Extra 260 25%
ORIGINAL: fjaust Any idea on the wing area for this plane? I was looking at peak website and saw the Extra + 40cc combo for a reasonable price. I'd be interested in working out the wing loading for this combo? Never mind, I just found the manual on peaks web site, wing area is 972 sq. in. Now how do I calculate the wing loading? |
RE: Peakmodel Extra 260 25%
I test flew the extra 260 with the peak 26cc engine, and the balance was achieved moving the RX battery pack the most in the rear of the fuselage i could, i think if you use a big/heavier engine you will have the add dead weight to the tail for balance.
This plane is well constructed and very very light, i would recomend you try it with the peak 26cc or oher good engine like the evolution 26cc, you will get excelente performance without sacrifice the balance and wing loading. Jose |
RE: Peakmodel Extra 260 25%
I just ordered one of these for my saito 150. Looks like a great plane. Looks to be the same plane that cermark is selling.

Now how do I calculate the wing loading? Dan |
RE: Peakmodel Extra 260 25%
I just found out that my new extra 260 is sitting at the local post ofice waiting for me to pick it up. I would have received it on saturday if i was home. So technically it would have only taken 5 days to get it. That is impressive! Hopefully it survived the long journy though.
Jose were there any issues with putting it together that you ran into? Was the hardware that comes with it good or did you just throw it out and use something else? |
RE: Peakmodel Extra 260 25%
The hardware is good, i used all the hardware, only the fuel tank i went with a smaller 10oz tank.
You will love the 260, realy a beaty, flies like a dream. Jose. |
RE: Peakmodel Extra 260 25%
Jose the manual does not give the spacing from the firewall to the thrust washer. What is your set at and what size spinner did you use? So far this plane is unbeleivable. Its strong but really light for its size. I have not even got to fly mine and i already love it.

As i sold the plane to a friend from another city, i can not measure for you now,. but i am posting some pictures of the en gine instalation.
I made some stands that were 1 1/2'' long. The plane is wonderfull, you can not go wrong with it , best 25% airplane i have ever seen or flow. Jose. |
RE: Peakmodel Extra 260 25%
I'm ready to take the pluge into my first gasser. This seems like a good first combo but I'm still confused about the following two issues:eek::
So what is the total ready-to-fly (dry) weight? The Egdg540/SPE26CC combo came out at 10.5lbs intead of the advertised 8.8lbs. I'm assuming the same is true for Extra260. Also, what is the correct wing area? The website shows 1016 sq-in but "fjaust" found 972 sq-in in the manual. 8.8lbs at 1016sq-in works out to be 19.95oz/sq-in wingloading. 10.5lbs at 972sq-in works out to be 25.12oz/sq-in. Any response will be much appreciated. Tony |
RE: Peakmodel Extra 260 25%
I did not weight the plane, but have flow it 20 fligths, and the wing loading is perfect with the peak 26 engine, total weight i estimate to be 8.8 lbs, the extra 260 is lighter than the edge 26cc, that i can tell you for sure.
I did not calculate the wing area, the plane is 70"wingspan, i have the QQ yak 72" that i paied a lot of money for it, and it is not half as good comparing to this extra 260, the extra 260 flights very light, total 3d and precision capable. The plane is wonderfull, you can not go wrong with it , best 25% airplane i have ever seen or flow. Watch the flying video with the peak 26cc engine : http://www.youtube.com/watch?v=3l7kIrdovv4 Jose. |
RE: Peakmodel Extra 260 25%
Jose,
Thanks for replying so quickly. I'm looking forward to my first gasser. |
RE: Peakmodel Extra 260 25%
i ordered one last night free shipping and i got the combo with the 40 cc gasser,i cant wait till it gets here

RE: Peakmodel Extra 260 25%
Jose:
How do you access the carburetor for priming?, since the peak 26 does not have choke. Can you reach it from inside, removing the canopy ? |
RE: Peakmodel Extra 260 25%
ordered mine yesterday morning. Blue one for replacing the ARF EDGE
|
RE: Peakmodel Extra 260 25%

Yes, removing the canopy i could prime the engine for the first flight of the day, than i had no need to prime the engine, it always started in the first flip.
In my 260 i used home made standoffs, these were shorter than the peak stands, doing this i managed the prop shaft to have small gap to the cowling, and the carburator enterede more inside the fuselage, making possible for me to put the finger in the carburator for choking (for the first flight of the day). Hope this helps, Jose. |
RE: Peakmodel Extra 260 25%
Hi, Do you think that a Saito 150 will really pull this plane with authority, for sport/F3A style flight? Regards, Mike |
RE: Peakmodel Extra 260 25%
Yes, i think it would be a perfect match.
Jose. |
RE: Peakmodel Extra 260 25%
Thanks very much for your opinion. It's very wellcomed. I have a 150 and I have doubts about if installing it ot not. Lots of friends are recommending me that Saito 180 is the proper one, and I am a bit confused, honestly. Maybe becuase they are thinking about unlimited vertical performance, which is a different history. |
RE: Peakmodel Extra 260 25%
Go with the saito 150, the airplane is very very light, i recomend using a apc 16x6 or 17x6 prop in this airplane and saito 150 engine combo, it will have unlimited vertical performance, no doubt about that.
Jose. |
RE: Peakmodel Extra 260 25%
Personnaly, I will use an OS 160Fx with APC 18x6W. With the ARF Peakmodel Edge, this motor was great. I'm sure it will be the same with this Extra. Saito 150 will be good with less power of course.
|
RE: Peakmodel Extra 260 25%
The edge is good, but the extra 260 is another world comparing to the edge.
It is lighter and better designed plane, the os160 fx would be rocket power in the extra. Jose. |
RE: Peakmodel Extra 260 25%
Eveybody tell me Extra is better. But for sure, the EDGE is really good.
I agree with you with the big power of the 160Fx and the rocket it will be with Extra as the wings are less thick on the Extra |
RE: Peakmodel Extra 260 25%
Mike i will be able to give you a definite answer on the saito 150 this weekend. As for props the 16x6 is way to small. I am going to start out with the 17x6 apc and maybe try a 18x6. I really think the 150 will be more than enough as this plane is very light. I am sure it will be lighter than the old funtanna 90 that everyone useed the saito 150 in.

RE: Peakmodel Extra 260 25%
What's up with the counterbalanced elevators? This is the first 260 I've seen with them.
|
RE: Peakmodel Extra 260 25%
just ordered an extra 260 w/ peak 26cc.
will the peak 26cc perform well just like in the videos? Jose, wat prop for the peak 26cc would u recommend? thanks |
RE: Peakmodel Extra 260 25%
I am really interested in the extra with the 26cc. Let me know how the power matches with this plane. I am thinking of the 40cc but don't want the extra weight if the 26cc will have decent power.
Dave |
RE: Peakmodel Extra 260 25%
dave i got the 40 cc for mine but i dont have time at the moment to put it together im thinking it might be too much engine
|
RE: Peakmodel Extra 260 25%
cmircman,
I will be really grateful if you give us feedback an small review abot tperformance with the Saito 150. Please, do not forget capture details as total weight of the plane, CG issues, vertical performance and props. I know, it is really a lot, but you are the first with a Saito 150. Your impression will benefit lot of us Waiting yours new, thanks and regards.;) |
RE: Peakmodel Extra 260 25%
I was thinking about the Brillelli 36gt I have read a lot of good things about them in the Extreme Flight threads. I have the Yak 54 74" but I put an O.S 1.60 on it, with the extra 260 I want to make the csange to gas.
|
RE: Peakmodel Extra 260 25%
MikeSteve I am mounting the engine tomarrow. So far this plane is really light. Once i have it fully assembled I will weigh it and give a final weight. So far the only thing i would like to change would be the landing gear. I did not care for the axles that came with it so i am swapping them out and the tail wheel i opted for a sullivan. Also the gear is heavy. I may start looking for carbon fibre. You could really save alot of weight this way. But over all I am really impressed so far. I really think this plane will come out within the advertised weight.:D

RE: Peakmodel Extra 260 25%
Ok guys just a little update. I have been working on the plane and will not get to fly it. I had to set mine up with the included pull pull ruder and i am having some balencing issues. As it stands right now with just a spinner nut on the saito 150 it is going to take about 3 ounces of lead to balence out at 133mm as the instructions give for a starting point. I did weigh my plane on a digital scale and with no wheel pants and the 3 ounces of weight mine is sitting at 9 pounds 6.6 onces. I am working on moving things around and loosing weight. I feel i should beable to get it down to 9 pounds.
