Hi!
What prop size should i use to my u-can-do 46 with the os 50 sx engine to fly 3d and hover good.

Try the APC 12.25X3.75 or you could go with the APC 12X4. Same prop sizes you would use on a 46. If she's a real good runner try a 13X4, but it would probably be too much prop.

i have try the master airscrew 12x4 because the apc is sold out here, the engine is at realy high rpm. is that dangerous?

I run a Master Airscrew 12x6. or wood 12x6 on my 50SX, not on UCD46. Pulls from hover better with higher pitch prop. On my UCD46 I use a Saito 82a with 14x6 wood. Again, better pull from hover.

My favorite is 12X4 zinger, very light, spools up instant, very good for slow rolling harriers.
