Fisrt off this plane could easily be flown with a jett fire 50. I used a os32sx with a jettstream muffler and a 9x6apc hitting 17,500 on the ground. We set C.G. at 180mm. The engine was not mounted at the 110mm from the fire wall that would of had it all the way at the end of the mount. we mounted it centered on the engine mount, which helped out on the cg. All throws were maxed out, and the only pieces of plastic we used was the red piece behind the canopy and the bottom skids. To get the cg correct the battery was put in the tail. We hand launched with about a 30 degree angle and pushing from the rear. The plane took off straight with just a slight dip after lauching. only a slight amount of right trim was needed. The f-15 tracked very good in a striaght line, but did seem a little washy in the turns, but nothing like it was out of control. speed with that engine set up was maybe just over 100. I would not fly this plane until deadstick with no power it drops like a brick. We set our timers for 3 minutes and then brought it down and cut the engine on approach. Engine was killed just after final turn. I have posted a video of the mainden flight and you can see that once the engine has been killed how quick it dropped, i had full up on approach to the landing. I was trying to get it past the ditch. Hopefully the weather will be better tommorow and we can get more flights on it. We had to leave due to lightning in the area.

A good "up and down" is always a good thing on a maiden flight !!! [sm=thumbup.gif]

That's a very sharp looking plane, they captured the flavor of the jet with some very simple shapes. Very clever design. I'll bet it is quite a sight to see. This plane with the .32 would give a guy who likes to work with props something to chew on. I would like to try it with an APC 8x8 cut down enough to bring the rpm up to about 18,000.

Just found this in the Jets section- some guy put a pop-can (AKA- turbine) in the Protech F-15 [X(]

Seems this plane balances better from the back---

As Razor has said,

Have a look at this little beast, the owner is debaker of the UK.

Ah... good flight report.

Gives me some inspiration to finish mine up a bit.

I have the engine mounted off at an angle a bit... helps the muffler clear the jet intake.

I cant for the life of me see flying the plane with an LA25 engine though.

Bud, what did yours weigh in at ?

Hah-hah, I like that. My new term for the hair dryers.

I thought the "pop-can" was clever, but I am often incorrect in these type of assumptions

Bob- What on Earth is wrong with the OS-25LA being run on this prop-Jet?

Huh?

Huh?

They are blue and *****en! [X(]

I do not even read the engine recommendations on these ARF's anymore.... It seems my Funtana-90 would have hovered at 1/3 throttle with a 90FX and stock muffler, and the Patriot is an awesome performer with a "ball-bearing 46" I selected the ASP-46 for my first Pat and results were surprisingly non-stellar. Go figure...

Don't even get me started on that SIG Kougar/Kobra post where someone is running a 4 stroker and flames---

thats good news. I have one due in any day now my JETT FIRE 30 BSE needed a home.

what servos did you use?

we used hitec 535 servos on the ail and ele and a hs56 for throttle. before mounting your engine i would do the rest of the buiding first and piece the plane together. install your battery in the rear. this way you can put the engine in the correct place to get the cg correct.

I bolted a Weston 50 on mine. I put servos and battery as far back as possible. I didn't use the factory tank as it was too small. Instead, I used a 3 ounce feeder tank near the firewall, and an 8 ounce tank just in front of the C of G.
Not flown it yet so nothing to report on handling. Wing loading is probably very high. Balance is at 185 cm.
Aileros are very small so I installed a servo for each elevator and enabled a modified vtail config. I may or may not need this. Needed the extra weight on the back end anyway.

Sweet! Let us know how it goes...

Flown my F-15 twice now. I hand launched it myself the second time. Flew right out of my hands. The West 50 really moves this plane.
I needed a few clicks of left aileron. Probably due to the big tunned pipe on the right. Good roll rate. Tracks fairly well in the corners. Vertical was certainly unlimited. A bit hard to see sometimes due to it's size and speed.

Landing is great becase it slows down when you cut the engine just as you are comming to the edge of the field. It's not a floater.
The added weight of the engine is not an issue in my mind.
