Hello guys,

I have a mustang .46 wich I love,

Now I want to put together a C-160 of nitro planes http://www.raidentech.com/ctrnigasrare.html , it says in the requirements I need 2 x .25, is that going to be enough???? I was also taking a look of the Mosquito and it requires at least .25 and preferely .32,

Thinking about engines for those size of planes, do you guys recommend 2 x .25 OS FX or 2 x .36 Evolution (I heard this engines are good)..... what should I do??? what do you recommend for both planes????

.....I wouldn't put less than two .61's in it.

FBD.

wow...... I didn't even consider 46 size engines!!!!

2 x .61????? is not that too much????? even if they recommend .25 - 32????

....keep in mind, if one engine quits you have to able to fly it on one engine.

You would have a tough time flying it with one .61. It probably weighs over 10 pounds
and has as much drag as three planes. In all seriousness, I would probably use a pair
of Tower .75's , or a pair of Magnum .91 four strokes.

Flame suit on.

FBD.

I have the Nitro C160 and have a pair of Thunder Tiger 25's for power. It flys fine with takeoff's in about 75 ft.Havnt experianced an engine out yet. I wanted more power so I popped in a pair of Mag. 28's. Better power and still no problems. I short filled one tank to see how an engine out was like and didnt know I had one till I did a flyby. It just is a little sluggish on the turns.

amazing plane, that is why I want it!

I thought that because they recommend 2 x 25-32 I could not mount 61 size or bigger....

Does it mean I can mount let's say 2 x OS 61 (2 stroke)???or did flyboy in the second post mean 61 refering 4 strokes ????????

I dont think that the wing would hold up with putting a pair of .61's on it With the .28's on it I can leap off the ground in about 40ft and climb out not exactly scale! Another problem with "mega-moters" would be the ability to carry enough fuel for a fun flight! With the stock tanks I get around 10-12 min of goofing off with the 28"s I see no reason to go larger than 32's on the motors-just my 2 cents

I understand, you are right....

I was thinking I want to use a couple of engines I can use in other planes, just in case, I have a spare .46FX, do you think it is all right if I install 2 x .46FX on it????? what do you think about it????

I was thinking about that because I am also interested in the Mitchell of nitro planes (2 engines) and it requires 2 x 46-52 engines, do you think that I can use 2 x .46FX for both planes?????

I can't speak with any authority about the Transall, but my observation is many people GROSSLY over-power glow/gas twins. You don't need single-engine
climb performance, if you lose an engine on take-off before you make the first turn, you should pull the power off and take what you can...the same if it was a single. Unless you are a very good pilot who understands what the rudder is for, great big engines with one out just leads to handling problems (like a Vmc roll into the ground.) You would be suprised how little a well-designed twin can do on one modest power. My vintage Goldberg Skylark 56, with two ancient OS .15s can climb slowly on one, even manage a loop and aileron rolls, and it weighs 4.5 pounds! My Boeing 247 scale twin was the same on two OS .10s; it was closer to four pounds. You are interested in controllability, not blazing single-engine performance...after all, you are over an airport all the time. The .32s on the Transall sounds about perfect! Russ Farris

I got the point, thanks a lot

I just would like to check if I could use 2 x .46FX in the transall C-160 (recommends .25-.32 engine) because I already have 1 spare and I can get another one from a friend of mine, I really like the performance of the .46 FX in a single engine plane, I would like to try it in twins planes.

Do you think they should be ok???

NObut its your plane,do with it as you wish!!!![&o]

Sorry for being so annoying but I am new with this and I still do not get a lot about what engines you can fit in what sizes of planes, I have seen people fitting big engines in little planes,

when you say the 2 x .46FX would not work out, could you please be a bit more specific to tell me why not???? just because they would be too big/heavy for the transall????

Thanks, I really appreciate this, I am learning a lot

OK, I know this is new to you.

ANY vehicle, full-size airplane, boat, car or whatever is a balance of power and weight. You seem intent on installing .46s on the Transall, which would probably work, but the airframe is designed and optimized for smaller engines. OK, I've been guilty of overpowering myself - I installed a Super Tigre .46
in a Das Little Stick (span 46") and it went vertical, unheard of in the 1970s. It was also terribly nose heavy, and needed lead in the tail. It makes as much sense as installing a 454 Chrysler Hemi engine in a Honda Civic

Matador, it sounds like you might need some more practical experience actually flying R/C before you spend the time and money on something as complex and critical to operate as the Transall (or any twin.) The Hobbico Twinstar (.20s are PLENTY) will give you twin experience on a minimal cost and investment.
Good Luck! Russ Farris
