I find I'm getting more fascinated with multi engined stunters. I ran across this one, and find the lines mezmerizing. The best pictures I could find on the net, were of a great plastic model by a gifted modelor in that genre, Brett Green.
The FW T-154 only had about a double handfull built, with a few actually being operational in several modes. The model shows a night fighter version with the Antenna arrays on the nose. It was first proposed as a heavy fighter, and inspired by, and in answer to Englands Mousquito. The Germans named this one Moskito.
The design elements look to be decent to base a stunter off of. I'll have to tweak the A/R, and increase the area of the stab and elevator, but I think the final appearance should look pretty scale like.
I've ordered a book on this design that has about all the information available, that should be here early next week.
Here're a few pictures of Brett's model.

That will be awesome John!!!!!!!!!
Derek ;D

Hey you already have a pilot for it too I bet ;)

I do, and a fine speciman of tuetonic perfection he is. I understand, that he used to fly a BF 109. S?P

Hi Brother John,
I , too, have grown fond of multi engines stunters and I don't even have one air ready, yet! LOL!!
The HE 219 will be my first one in the air. A 1973 (Nos. 30 legal!) profile design originally based on two slant plug Fox .15s. I have a few OS .10FSR that I believe will do MUCH better. After that, probably a P-38 as designed by Don Hutcherson w/two .20FP.
(too many models never engough time.............. ;D )

John,, dang it,, sigh,, I guess I really should paint the silly thing, but its a slimer,, and I am going electric,,

It appears to me that twins, and other multi's have a definate advantage flying CL stunt. The biggest handicap has been ourselves, wanting not one, but two honkin' engines mounted.
When I saw Paul fly his B-17 with 4 OS .15FPs, my eyes were opened. I have the advantage of having one of the best multi engined stunt pilots as a flying buddy. When we built the pair of Pathfinder twins, also powered by OS .15s, we found that using a pair of these smaller engines, totalling .30 sq inches, on a plane sized to what most people used at least a .40 or a .46 on, gave up nothing to the larger single engines. It seemed, as is probably a fact, that the increased prop disk area from two 9 inch props gave us the edge we needed.
The simple facts are that twins, using a pair of large engines, can, and do, handle the pattern with authority. The problem comes when the conditions begin to get edgy. Gordan has related that as the wind comes up, and the line tension goes up because of it, and the plane becomes uncomfortable to fly. He says that the plane may be capable of doing the pattern in those conditions, but, you wind up just hanging on trying to avoid the loss of the plane. As he says, you can't finess the plane under those high, line tension, conditions.
Smaller twin designs, using the smaller engines makes it much easier to do good patterns under wider conditions. And consider this. The prop disk area of a pair of 9 inch props, exceeds the disk area of the normal 60 sized prop.
The biggest draw back to twins, is learning how to effectivly set up, match, and tune, a pair of engines for best results. This is one of the many areas that Gordy excells. He can get a pair of engines running real sweetly.
For those of us less gifted, I believe that electric may well be the best answer. An added benefit is simple retracts. (Wooohooooo)
Bill, at first you'll be frustrated with twins, after a while you'll find them so much better than a single #^.

You know there is a one liner in there,, but I promised to behave, so I will leave it alone,, besides,, LInda may be watching then I would be in trouble,,

Mark, your a good guy, Linda mw~ has you whipped into good shape. y1 LL~ LL~
I really hope you can make your way to Tucson in March. It'll be a blast.
-
I am working on it,,
the desire is there, no question, its more about a few logistical issues to sort out,, like the whole work thing ,,,,,

Meh. No issue. You simply say "I'm not going to be here the 3rd week in March!" Problem solved.

Hey Clint, when they say " fine,, so where shall we mail your last paycheck then,," I trust you will offer me a position with equal pay and benefits LL~
-
Well, John, this confirms it. You need medication.
-
Randy,
I am thinking I may need medication, or counseling,, maybe you can help me? sigh
-
Well, John, this confirms it. You need medication.
Does this mean I are a real "modul desiinr", Or do I need counseling too? Hey, I need the straps on this jacket loosened just a little. n~
-
John, a note of experience, if you use a track ball instead of a mouse, you can still work with the straps on the jacket tight ,,,,
-
that is one cool looking airplane - cant wait to see what you come up with.
-
John,
Wait till you see what I'm planning for my next PA plane. ;D ;D
-
Thinking of a twin Randy?
-
Randy promised me he was going to start on a 4 engine bomber next.
;D
-
John,
No.
PJ,

Yeah, back in the day I had a crush on a twin. Unfortunately she wasn't interested beyond "friends". Her sister was game but I just didn't have the same "feeling" for her. ???

Hi John,
This will be another great project. I see a tremendous advantage in twin for the VOLTS GUYS!
Cheers,
Martin

John,
That is a great project. It has been a few weeks, is it in the air yet?? ha ha
-
Not in the air yet. I've collected documentation though. I bought a great book on the aircraft, and a fairley accurated plastic model to construct, so I can get the snapes right in my mind when I start the drawing process.
I suspect this one will be prefect for electic power, with retracts.
