Default "50" size planes

I like to surf-like most of you guys do- for my next plane. There seems to be more and more "50" size planes out there. I like the size and portability that comes with it. I am currently running a couple of 46's, but am realistic to think that a little more ump would work better(46 is probably on the under-powered side of the range).

For now, I would like to stay with a 2-STROKE. I know eveyone is in love with their 4 strokes(they seem to be a little expensive). Are 60 size too heavy? I have been looking at Aeroworks, World Models and Kyosho planes. For now I am talking about general sport flying and intro to a little 3-d. Thanks for the input.

Take a look at the OS 55 ax [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNMD1&P=ML]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNMD1&P=ML[/link] Sounds like what your looking for.

I believe that there are 40 and 60 size planes... this 50 size is just a 40 size that they know you are going to want to stuff more engine into. The average 40 size plane weighs between 4-6 lbs and I would bet your "50 size" planes are in that range. It's just marketing for the most part. You will notice that the first feature of the OS .55 AX is that it fits the same mounting dimensions of a .46 AX wich also happens to match the venerable .40 FX. Now this of course is just picky semantics but to answer your question if you are going to play with some 3D then you will want the OS 55 AX on a "40/50" size aerobatic plane. I have one on my Hanger 9 Funtana 40s wich is just the predicessor to the Hanger 9 Funtana X50. They are esencially the same basic plane with a few nice redesigns to the airfoil but either would fly with the same authority when matched with the same engine.

I bought one of these and it is excellent. It fits in the same space as a .46 but has a little more power. The thing runs nice too without needing a lot of tweaking.

Stang--I think that what you posted makes sense. I guess it comes down to weight, airfoil type and a host of other things. I would love a Saito 82, but for the price I can get the OS 55 and almost a flight pack. It all comes down to marketing.

ArmedZagi: Check out www.westside-rc.org(in nearby Yukon) and www.torks.org(North OKc by Lake Hefner) Both have very friendly people.

Also, make sure they're not talking about 50cc which is a lot bigger than "50-size"

Minn-thanks for the input. I guess since I am asking questions, the correct title should be .50 planes and the engine is actually an O.S. .55 AX ABL w/Muffler. We all learn together here. The Beginners Forum is kind of like swimming in the shallow end of the pool.

The .50-size two stroke is actually a pretty popular engine size:

O.S. Max .55 AX
Kangke SK .50A
JBA .56A
Magnum XLS .52A
Super Tigre GS-51 Ringed
Evolution .52NX

These are just examples off the top of my head, I'm sure there are more. Most ".50-size" ARFs are designed to run off a ball-bearing .46 2-stroke or .70 4-stroke, but are too heavy or too high-performance for a plain .40-sized bushing 2-stroke or .52 4-stroke to power them with the authority that the pilot will want.

About 6 times bigger in fact. 50cc=3.05 cubic inches

I'd look at some Super Tigres. I run the 2300 in my GP Giles 25%er and it runs GREAT! Can't beat the prices for them either!

I tried 60 sized motors on 40 sized planes and the penalty you pay in terms of a heavier engine is not what I would ever do again. With today's lighter planes they are building bigger 40 sized planes, all in the 58"-60" wingspan category. Fliton is one of them, the planes are big 40 sized planes and they are light for its size. Lovely planes to fly. All rounder where you can fly as a sport plane, for IMAC or 3D. Should be good with something like the OS55AX.
