engine/plane combinations
 
I have a Os MAX 55 ax here doing nothing, so i'm looking for a plane.

I'm having general problems finding "55" size planes.

I know in a 40 size plane the engine would never really get its "use" as my trainer is a 40-46 with a magnum 52 and it never really gets a decent reving.

Would the 55ax power 60 size planes sufficiently?
I'm thinking something like the hangar 9 ultra stick 60 or the kyosho calmato 60 low wing, etc

Basically i know that 55 is 5 less than 60, but will that missing "5" result a poorly performing plane or will it do what it is designed to do?

The .55 should make a mean engine for just about any .40 size warbird or aerobatic type aircraft. It's a very good match to the Mojo .40 profile.

Maybe a Sig Four-Star .40, one of the Kyosho .40 warbirds, or the GP Venus .40 pattern plane? I would steer away from most .60 size planes but, depending on the particular designed use for the plane, a light one might fit the bill.

What you'll miss most from having that 55 in a 60 size model will probably be weight, not horsepower.

The 55 is basically a 46 replacement and as such was kept down in weight. Most 60s are significantly heavier than most 46/55s. And the planes designed to take a 60 are going to have that weight considered in the design.

The 55 is about an 18 ounce package. 60s are going to be around 24 ounces. Balancing to make up for 6 ounces probably won't be possible without adding lead.

There are lots of 46size models that'll work better with the extra power and won't need any dead weight. That contrasts with plugging the sucker into an airplane that isn't going to want less power and starts out heavier than the 55 was actually designed to pull around.

Stick the .55 in a Great Planes Revolver. It is a perfect match up. It also works well in my World Models rambler 45. You'll find plenty of 40 class high performance planes that will be even better with the .55.

If you can find one in stock the sundowner 50 would be a good sport model.

It will operate anything in the 40 to 50 size planes, just way too many to mention!! Weight not horse power?? Me thinks da rock is smoking da rock??

If you cant find anything to put it in I might can take it off your hands in a trade lol. I have one in a Phoenix extra 300s and it calls for a .46. Great combination and this motor will spin a 12x8 prop with no problems even running rich.
