Mine is ready for it's first test flight now that I have the JR Match Box installed. Tried to fly it on Sunday but the winds wouldn't lay down enough for me to want to try it with a cross wind. I did fire up the big Saito 1.25 and dialed it in, Man talk about a great running engine. I will try to test fly it again on February 21.

Good luck with your maiden. You'll love this plane,especially with the big Saito. Jim

Balsadust, Get a chance to maiden it with that 1.25?

sbsam

How I said, i put the SK 1.30 2t with pitts muffler.

Some pictures...




I should see the CG.


Thanks!

If anyone is still looking at this forum, Have you heard of someone putting a 26cc gasser on this model? I just mounted my XYZ 26 on it and from what i can see, it was made for this airplane. The cowl fits perfectly, only had to cut out for air outlet, and a little for the muffler. Just wandering about weight affecting how it will fly.

sbsam

Friessen i wanted put this motor! but i had a doubt if the xyz26 would fited in the cowl.

Do you have a picture of plane with the motor?

friessen

I have not posted pictures as of yet, but i'll try to post some tonight. But i can tell you that it fits perfectly. Just knock out the blind nuts center the engine in the same place a glow engine would fit, mark the holes and mount it. There was no cutting of the fire wall. I only cut out just enough of the bottom of the cowl for the muffler, and enough for air flow and it was done. Took me about 1 hour.

unfmoose

Yeah, I would like to see that...I've been considering changing engines lately but haven't decided.

friessen

here are the pic's. still haven't balanced it or weighed it, but i'm planning on doing that in the morning after i tune the engine.

My Feedback: (12)

Hey friessen, thats a big chunk of fudge you stuffed in the cowl of that extra. Let us know how it flys with that engine. I'm sort of doing a simular project. Showtime 90 with a MT35 gasser.[X(]

friessen

Hey all-
Just maidened tonight, and can I say, "Holly S@#T". This thing is squirlley. I thought my SEAGULL EXTRA was bad, but this is quite a bit worse. My first thought was I had too much tail weight on it. So I took some off and that helped, but it was still touchy on the elevator. On top of that, the engine was running like crap. But it still had lots of power to climb forever. When I landed it to adjust the carb, I think I need to add spoilerons. With the weight and touchiness is is a handfull on final. I shut the engine off after the second flight and noticed the prop was 1/2 inch shorter than it was on take off, the canopy scews were missing, and it had a 20 degree tilt on the gear. but other than that, it was fine. So now I'm going to tune the engine, and fix the canopy screws with metal insted of the plastic, and program some changes to help it out a little. Let you know more latter.

What is your AUW? (measured on a digital scale, not a spring scale)

Where is CG?

I'm gonna go out on a limb and say 8.5lbs?
That and the gasser will shake it to pieces in no time...

cmoulder

At least 8.5, maybe over 9 truth be told. With that much mass up front I can imagine it took a ton of lead in the tail to balance.

Well, if vertical performance is the only criterion...[]

A few months ago I maidened a clubmate's kit-built GP Extra that was considerably overweight - the "heftiest" Extra I have ever flown. Flew just as described above... lucky to get it back in one piece.

This is a delicately built, lightweight model. Not a gasser, PERIOD.

friessen

I don't have a scale to weigh it, but i bascily took all the stuff from my Funtana 100x and put on this bird. The two airplanes are built about the same, but the phoenix is built better, but a little smaller. Thats why I used the gas. I also have small hard rubber pads behind the engine mount to help with the vibration. As far as the balance, I used the recomended c/g in the manual, and it took 1 1/2 sticks of stick on weight, which comes out to 4 oz. I'm getting ready to head out and TWEEK the engine and play with some of the balance. So I'll give you all a run down tonight. Wish me luck.

Good luck, and dont forget a garbage bag!!!

wingboz

I have one of these planes, I DO NOT understand why you all keep on putting on BIG engiens!!! These planes are not build for that much power. If you JUST HAVE to have a BIG POWERFUL engien then go get you a BIGGER plane. I know that the price is right for this plane, so why not just enjoy it as it was intended. FLY the C&#%E out of it, learn all you can about 3 D
flying cheap. THen GO TO THE BIG PLANES!!!!

Alright here is the status report,, My CG was waaayyy off. Took 3.75 oz. off the tail, and it flew great. I still need to tweek the engine just a bit, but both plane and engine are working good. The only thing I noticed was that I need to add a little more right thrust. Plus I need to lock tite the control horns. In reply to wing boz, the reason I went with the gasser is because gas is cheaper. Yes I know it's over kill, but it sure is cool.

maynardrupp

I agree about the big power trend. I have an OS 75AX in mine and it climbs straight up and out of sight if you let it. I do a lot of practice for Sportsman Patterm maneuvers and most of that is at 1/2 throttle with the 75. Vertical stuff is easy also. I don't do 3D so I cannot speak to whether this OS 75AX is up for that in this airplane. It really has a ton of power though.

friessen

I would normally agree, however I got this airplane to expermint with. I'm new to the gas engine world. I got the 26cc engine to put on my Funtana just to find out it wasn't as powerful as i'd hoped it would be and lost the plane due to my lack of knowledge. I got the Phoenix extra because I wanted an inexpensive airplane to learn how to use gas engines. But I also thought it would be neat to put a gasser on this plane just to say I did it. I'm not mutch of a 3d pilot but i thought this would be a nice stepping stone before i spent $2,000 on an airplane just to find out I didn't know what I was doing.

Maynard,

I would guess you'd swing the other way considering your background and all.
BTW, I'm a 60's era drag racing junkie, born a generation too late. Love them straight axle gassers!

Friessen:

No guts no glory, eh? We have found that replacing those metric canopy screws with 8-32 nylon works well- they are just perfectly mismatched so that they are a bit "sticky" and don't vibrate out. You don't even need to reef on them to keep them tight. Just snug them and fly. Details of why I think that this works on post 830 at http://www.rcuniverse.com/forum/m_47...tm.htm#8774187
Glad you got the CG in where you need it without making a pile of toothpicks.
Be sure and use a good dose of expo to reduce the twichiness.
Unless it is landing really slowly- which I doubt with the big Gasser up front, I would not expect that you need spoilerons with the extra weight it should grease right in.
Gas engine test buck- hmm-never pictured that for this light plane, but good luck with it. As long as you aren't expecting hundreds of flights out of it and keep the props balanced, I think you just may get what you are looking for out of this plane.
PS there are a lot of safety precautions with gassers that you should be aware of, such as kill switches, looping the ventline in 2 different planes to avoid spillage during stunts, and a fire extinguisher. Hope you have seen all of that stuff already. I'd go on, but I'm new to gassers as well... putting a ZDZ80 on a 1/4 scale Stearman this year.

As for the gear, Maynardrupp did a good job of finding some stronger gear from TNT (better aluminum) around Xmas 09 if you go back ~120 posts:

$50 with shipping but you gotsta drill your own holes!

Min$- Thanks for the positive response. I've flown it about 20 times now, and it keeps geeting beter. As far as weight, it really seems to handle the weight from this motor quite nicely. I cut open the covering at the tail end just before the servos and put the battery there so as not to add more weight than necessary. While flying, I can tell it has some weight because during harriers, the wings rock a bit, but not as bad as i've seen in other planes. The landings are verry easy. It comes in real nice and I can get it to touch down like I know what I'm doing, but it could still use a little spoileron. I'm still trying diffent props to see which works best, so far the APC 17-6 has been best, except that one take off I turned it into a 16-6, if you get what I mean. All in all this is just a fun plane to fly, and learn on. P.S. yes I have incorperated the items you stated above. A good friend of mine told me about that when I turned my funtana into a gasser whith this equipment last year.

I had a 26cc gas motor on mine and all it wanted to do was fallout of the sky. It was only 9lbs AUW.
