F82 Mustang Twin
Just purchased a Tower Hobbies Fun 51 kit. Nice little kit although looks a bit on the small side to me. I have been wanting a twin for fun flying and to have something a bit different. Also a bit of a break in the scale building department. Has anyone taken one of these profile kits and converted it into a twin? It has a 44" span and only 32" in fuse length. I am considering a 60" span 40" fuse length and using two .46size engines I just happen to have. Looks like a simple conversion and could be a lot of fun in the flying department.
Any one already tried this? Thanks

RE: F82 Mustang Twin
I haven't done this mustang but have bashed a few twins. If yo uadd a 12" center section that would be good. The Fun 51 is a bit short so it would be nice to lengthen the fuses and 40" is about right. The only real thing I dissapree on is the .46 motors, I think they will be too much. The Fun 51 is a slow fly plane and the twin would probably be happiest on .35 to .40... I understand there is a throttle and you could prop down to a 12X5 to use the .46's...

RE: F82 Mustang Twin
I agree on the fuse length and wingspan. I plan on adding 8" to each tip for a total wingspan of 60". The OS LA46 motor is an entry level power plant and very light given it has bushings. It would certainly be very easy to over speed this plane.

RE: F82 Mustang Twin
I looked into doing a P-82 Twin Mustang out of 2 Fun 51 kits, but never got around to it. The 82 was really a different plane, even though it looks like Mustang at first glance.
The 51 kit has a span of 45" and an area of 630. Extending it to 62" will give an area of 886 sq in. The fuselage length goes from 34.5" to 44.3"
Visual differences are:
1. The top of the nose on the 82 is a straight line, where the Mustang is curved.
2. The canopy on the 82 is forward of the Mustang.
3. The air scoop on the 82 is further forward.
4. The 82 is longer.
5. The 82 has a taller tail like the P-51H.
6. The 82 tail wheel is further back.
I was planning to use 2 OS .46AXs. I have a twin fuselage version of the Sonic 25 with 2 OS .46LAs and the AXs will be better.
I would also recommend a flap in the center.
If you drop me an e-mail, I'll send you some better 3-views. These are gifs and they don't publish very well.

RE: F82 Mustang Twin
I have decided to build this fun fly into a fun 82 or F82? Hmm! If there is interest I will do a building thread. Never done one before from start to finish, or "finished" in this case if it won't fly! Hollar if you want to see a build thread, enough hollern' and I will give it a shot. Maybe shot is a poor choice of words?

RE: F82 Mustang Twin
Well I did decide to build or bash this kit(s) to make a stand way off P82. Here is a bare bones picture before I start to cover. Outer wing panels plug in.

Dangit, now I'm thinking about this. As if I needed another project on my list...
Keep us updated on how it flys.

If it does not fly I know where you can get a great deal on two re-kitted Fun 51's!

RE: F82 Mustang Twin
I am using OS .46 LA's. Flap located between fuse's, the elevator and rudder servos mount in the bottom of the main wing along with the flap servo, reciver and battery and switch harness. I have found a grey nyrod to run down the inside of the fuse halfs. Rudder on one side and elevator on the other. I will use a drag ling between the rudders. Outer wing panels plug in and contain a servo in each for the aileron control. Each motor has a Hitec HS81 servo for throttle control and a six ounce fuel tank. The radio is a JR Spectrum DX7 using a total of 7 servos.

RE: F82 Mustang Twin
I just have the radio install to do yet and then it will be ready to break in the motors. Hope I will be ready to fly yet this year, as other projects are taking more of my time.

RE: F82 Mustang Twin
.46's will be way too much power for this plane,
in my opinion. Two .25's are hot hot on my Dazzler
Arf, that I bashed. It's much faster than my single
engine Dazzler with a .70 4S, and my buddies Dazzler
with a hot .46 2S.
Be sure to detune the aileron throws from what you
are use to on your similarly sized singles. The prop
wash over them make them much more responsive/
effective.
Good Luck!

RE: F82 Mustang Twin
Thanks for the advice. I plan on flying this as soon as the farmer cuts the corn. The tall corn makes the approach short and the field shorter. On top of that it eats planes, another pilot still has not found a plane he lost.

RE: F82 Mustang Twin
Flew my Twin Mustang last evening and put in a couple of pleasant flights. The engines were well broken in with Byron 15% and ran well, with just a little tuning on the high end. Plane broke ground in about 20 feet and only required some up elevator trim. Flight was very stable and fast with the .46LA's and the sound was like music to a nito lover's ears. Most of the flight was at 1/3 or less throttle, lots of power in these two motors for this size plane. Model slows to a crawl for landing without using the center mounted flap. I did test the flap out at altitude and the aircraft pitched down about 25 degrees, more testing and adjustment for this area for sure. Aileron and elevator were just about perfect with lots of control and the model felt solid. Rudder notas effective but I will have to live with what I have because the elevator prevents more rudder travel. If I were to do it over the vertical stabilizer and rudder would be larger by at least 25%. All in all a nice model and fun to fly. When I went up flying stopped and it looked like others enjoyed it as much as I did.
