I'm not sure where the CG ended up. I'll check that next time I put her together. I do know that I need a few clicks of down trim at the beginning of the flight and then a few clicks of up as the saddle tanks start to drain.
I also find myself flying with the left stick full forward most of the time - and the speed just about stays constant - no real increase on the down lines, it just motors around.
I've also found that the best takeoff technique is to go to full throttle and just steer and let it fly off when it wants too. The takeoff run is fairly long that way, but when it finally rotates on its own there is no more "struggling" into the air that sometimes occurred when I rotated it myself.

Hi Guy's,
do do you use your Flaps, and if so, do you mix elevator up or down with the Flaps?
i have build the F4 with twin EDF and want to fly her next week .
thanks

I had an accident on take off #2. Due to a large runway crack I lost my steering and went into the rough. The plane is rebuilt and ready to go. I have very limited access to a long (airport) runway and have been waiting for an opportunity to get a few landings under my belt before attempting to fly it off the short runway at my home field.

I have one and I love(ed) it! It flew awesome on a P-120SE. With a 140-sized engine that was the same weight as the 120, it would be *perfect*. I would fly mine around with the left stick pegged and it just went where you pointed it. You could horse it around in the turns and keep it really close actually.
Unfortunately, my P-120SE started loosing power on a flight at Virginia Jets a year ago and by the time I realized that it wasn't coming back up to thrust, I couldn't make the runway and it landed in the top of an 80' tree. I got it all back, eventually, and about 1/3 of it was salvageable. I liked it so much though that I ordered a new fuselage and wings and I'm rebuilding it. I should have it up and running next season.

ps - I think I saw yours or one exactly like yours, in the RCU classified a few months back...

Thanks for the tips on the Skymaster accessories[sm=teeth_smile.gif] guys
Here is the fuse. Nice mild weathering to highlight the fuse detail. Again all graphics are painted. I am not sure that the white sections are as white as they should be to be true to scale, but I like it non the less.

I just built 2 of these recently, a D and E. I do not agree with a lot of the negative that was said in this thread about the model, but there are a few changes that need to be done. I also flew both models, I have 9 flights total so far. One has a K100 and the E model has a K120.
Yes, you will need to pop off the strut gear doors and sand down the ply so you get full travel on the struts. I glued them back on with Hysol.
The D was ready to maiden, I was just starting on the E at the time of this picture. Both have since flown.

Thanks for the input. I had to cut 1.5" off the intake for the fuel tanks to fit. The next thing is figuring out the rudder. Not to mention the tight fit for the elevator servos and the elevator slightly off center causing it to rub on the fuse. Great paint job though. Got the Warbird Pilots to fit into the cockpit with a shoe horn. LOL it's work but this is a hobby.

You are on the right track, make sure to fit your turbine before you finalize the saddle tanks. Also make sure your hatch fits when you do set the tank location, mine was a tight fit.
For the rudder you can fit a standard size servo in the base of the vertical. The hardwood blocks were provided.
The aft block is up against the vertical spar. I have yet to round a spot into the block for the servo wire.
The stock tanks work great, depending on your throttle setting during the flight you can get 6 or 7 minutes on the saddle tanks. So the issue with the forward tank being the wrong shape early in this thread is not an issue. Sustained inverted flight should not be attempted after 7 minutes, because the forward tank cannot draw fuel inverted after about 1/3 of it's fuel is consumed. You must re position the hole in the saddle tanks to a more center location. I had some Kevlar in stock, so it was easy to cover the hole and move it.
This is a picture from earlier in the thread, I did not take a picture of mine.
I'm working on the paint now, I'm fixing many of the inaccuracies of the paint job. I think Skymaster uses the stencils from the 1/7 version on this smaller one. Here is what I did to the shark mouth, they painted the black nose cone on the wrong panel line, it's too large. Also the shark mouth looked like a big mouth bass.
I will do a full weathering job after my graphics show up, I'll be doing "The Wreckin Crew"
Got to keep the Mud Daubers out, so I ordered some intake covers from my local Phantom supplier!
Vacuum formed out of .015 polystyrene, they really look good when she is sitting on the ramp!

Flew at the Selfridge ANG Base Air Show Centennial Celebration. Great day and perfect flight performance.

It is nice to see interest in the Xtreme F4 Phantom. I am getting ready to purchase either this one or the Skymaster 1/7.75 F4. Working with Dirk as well. What is the fuel capacity on the Xtreme F4 Phantom? I was thinking about using K140G2 for the extra power. Does the 120 seem adequate for this jet?
Thank you,
Jeff

From what I understand the KingTech 120 will be the best size for this jet with the extra umph at the top end for go arounds and vertical performance.

Maybe dionysusbacchus will chime in since he has one with K120 and another with 100.

I have a Jetcat P120 in mine (currently being repainted...) The P120 was definately NOT too much power for this plane, and if I had a 140 with decent fuel consumption and weight, I'd put it in it.
According to the specs, the K120 puts out the same power as the P120, but is a bit lighter. From the specs, the K140 would seem to be perfect for this airplane. Fuel consumption depends on power setting and with a P120, I'm at WOT almost all the time...
