Webra 120 question
It seems that my Webra 120 speed has a very small prop driver for the power that the engine puts out. Anyone have a problem with the prop slipping? This is a new engine, i haven't flown it in a plane yet. Here's a photo of the prop driver on my Webra 120 compared to the one on my Magnum 160 and a MA 16x6 prop. The driver doesn't even contact the outer edge of the props hub, or should i be using a different brand or model on the Webra? The engines prop range is 16x8 - 18x6.

RE: Webra 120 question
Well i tried running the engine with the MA 16x8 and there seems to be no sign of slippage on the driver. I won't be able to use wood props on it because the plane it is going on will be on floats for water flying.

If the prop washer does not engage the outer "hub" or ring of that prop, I would find something with a solid hub to use. I would not trust that hollow hub. That MA may compress or loose grip over time. APC props work well on that motor.

RE: Webra 120 question
I think i will use APC props on this engine ( a 15x10 or 15x9 is what i plan on using ) I will use these MA classics on the Magnum 160. The Webra did turn the MA 16x8 really good at 8500 rpm at a rich 2 cycle setting. I'm impressed with the power of it, it started dragging my sawhorse it was bolted to across the cement.
