I did the 27% cap, was a real easy conversion. A guy in our club has the extra and it flies great on electric power.

I did it with a axi 5330 on 10s and it has lots of power...It mostly flys around on 1/2 throttle and lands like a charm. I had the same plane with a da50 and the axi definately has more power, or atleast it performs better.

well I pulled the trigger on it, I ordered it last night. gonna go with the 5330 sized motor
and 10s most likely. maybe even try a123 cells on this one. what prop does the 5330 like on this plane.
these are the servo's I'm thinking of using on this plane hs-5645mg

I've been considering this one also. I have a powersystem from my EF 74" Yak, and while the Yak flies great, I'm just not real crazy about yaks, and just cant get into flying it.

I've got a Hyp 5025-22 that I'm thinking of putting in it, I'm worried that it might be a bit anemic for this plane. If I can keep it light it should be okay, but after that I might be a little under powered...

Please post the dry weights when the plane arrives. If it's not to far out, then I might have to give it a go also.

I've been flying the Yak on the 5645MGs and haven't had any problem with them. If I go with this plane, I'll be using the 6545s also.

[booger]

should be here tomorrrow, If I get some time I'll post all the weights and include some pictures of it as well.

[NumbSkull]

Great!! Thanks!!

I'm really interested in seeing the hatch area. I've seen a few pics of it, but nothing that shows it comparison to anything that I can judge size by.

After running some numbers, I'm starting to think the Hyp 5025 should do just fine. They Hyp motors have proven to by underated, and the 5025 is rated for upto 2500 watts. So even if the plane comes in at 13lbs, that still about 190 watts/lb.

I'll probalby have to invest in some new packs to hit the 2500 mark, but I can always use new packs.. :D

I'll be in Ft. Worth in a few days, and I'm hoping to find one at one of the shops there (or in between here and there). If I cant find one in stock somewhere, I'll probably just order one in when I get back.

updated first post with pics and weight's
now if my other parts would get here

[NumbSkull]

Thanks for the weights and the pics!! The empty weight looks real good. I need to sit down and do the math now and see what the expected weight is with the gear I have on hand, but shot in the dark is looking promising!!

Here is my blog post about the Extra 260 from about a year ago.

I have now changed my setup to the Hyperion Z5030-18, 10s 5000mah, and a 22x12 prop. Awesome setup.

Hey Jon,

I had seen your avatar in some of the other threads, but I must have missed your blog posting.

I had ran my 5025 on 10S with a 21x10 prop on my Yak. The packs I used were some old generic packs. I'll be upgrading my packs to something a little better, and I'm hoping that I can push the 5025 up a little. I would like to go up to a 5035, but after looking it over, I noticed that it's only rated for 200 watts higher then the 5025. So I'm going to try and push it to get the extra going.

[booger]

I am surprised more people have not converted this plane. Since posting this thread it looks like a few have done it.
So all you that have converted this plane give us your tips and tricks for this plane.

[NumbSkull]

I was surprised as well. I had been looking this one over for a few months, but haven't found much info on it, even on the other sites... (I swear, I only strayed long enough to look for info on this plane.. :D).

I'm guessing the quarter size class isn't very popular. It's hard to find info on this plane even from the gas guys, and good looking planes in the class size are hard to find. There is a handful of planes out there, but not much compared to the 35% class.

How did I miss that one!!!

I had looked, and searched and never did see that.

Thanks authomassen!

Booger, where in oklahoma are you located?, I fly in Oklahoma City by lake heffner at the torks, you are welcome to check mine out.
Kevin

[booger]

I'm in Bartlesville i fly with the barlesville falcons at copan model air park.
we are having a fly in next weekend.

[NumbSkull]

Bartlesville isn't to far from here, and I'll actually be passing through Ok City tomorrow. We might have to get all the extras together and compare notes sometime.

[booger]

The more I Have looked over the manual and the parts of this plane the more I like it.
the motor i have with speed control is 2 lbs 3 ounces servo's and batteries around 3lbs hopefully. so hopefully an all up weight between 12 and 13 lbs
how much is your all up weight? Kevin
Rob

[rosek007]

anytime you guys are ready we could probably meet at a mutual distance away from each other.
Booger i have to weigh it.

I have seen the Axi 5330 system in action and it does work.

Please consider the following option.

The Hacker Power set 1.60 (http://www.aero-model.com/powersetdetails.aspx?id=eps160) has been optimized for this model, It will offer about 24 LBS of thrust and give excellent part throttle efficiency. Keep in mind the Hacker system was developed especially for Aerobatic models, that are flown in many conditons from calm weather hovering to Windy IMAC stuff.

The A60 has an excellent and strong prop mounting that can be used for serious blenders and extreme off-axis snaps. For 2007 we have also incorporated mutiple internal and external fans for total reliability on cowled models(Especially in long hovers). If you are serious about Aerobatics you should take a close look the Hacker Power sets, I know you will not be disappointed.

well I hinged the control surfaces and installed the front landing gear.
had to open the hole a little for the hinge shoulders to get a nice small gap between control surfaces
sealing the gap is next after the epoxy cures

I would love that power system but not in the budget for this model, as I am using alot of parts I already have for this plane. only thing I really need is the batteries and small miscellaneous parts and the servo's, I went with the hitec 5645mg's

I have a Topflight p51 about 21lbs rtf, do you guys have a motor that will make it go about 100 :D ?
i have only used axi's but have been wondering about hackers, i do like the hacker motor mount setup better, a little more secure i think.
How much is the one for the 260? might just try it.

Conversion got side tracked? :confused:

[NumbSkull]

I was thinking about that earlier today. Haven't heard much. But if it's like my builds.. they tend to be limited to the weekends....

Still haven't pulled the trigger on this one yet. I had a bunch of lipos go south on me over the summer from being stored to hot at full charge, so I'm trying to decide of I need more packs or the plane first...

A flight report and maybe a video will give me a hand in the decision....

[booger]

Guys, I am working on it but busy as heck at work. and the kids sports are keeping me covered up. but I'll try to get some more pics for ya. I have the motor and speed control mounted now.

[booger]

update with pics. this is really a simple plane to build hangar 9 does most of it for you. but on to the pics and the first test with a 20x10apc prop and some tired batteries but they did the job for the test
this test was on 10s

[booger]

12s tested on 20x10 apc prop

[hermperez]

Booger, which 5330 model did you use? what esc and which batteries?
I can see in the wattmeter 38v, 57A and 2255watts.

12s tested on 20x10 apc prop

[booger]

it's a towerpro 5330-10t with the hobbywing 100amp 12s esc and the batteries were a mixtur of my older 4000 3s and 2100 3s packs to get 12s 4000mah
(they are tired)

[booger]

well It is finished just waiting till I can come up with funds for a large battery purchase
