Max-Thrust/MX2 - Prop and Spinner Size Help

[Jay Naker]

HI peeps, I have this MX2 plane - **LINK**)

I want to change to a 2 prop blade and buy a spinner for it.

I heard 14.7 2 blade is good, what do you lot think? [B]Here is the link to the ''2 blades:[/B] **LINK**

[B]Also what size spinner would I need out of these:[/B]

The spinner should be the same size as the original 3 blade as it needs to match the front of the cowl. Not sure about the prop size as you did not mention the size of the 3 blade. Just check that you leave enough ground clearance with the larger diameter (same pitch) 2 blade.

Hi thanks for the reply. the Spinner is 62 x 105 mm and the original prop is 12 X 9

So what size prop do you think I should get and the Spinner from the links in my first post. How about a 14.7 prop and dunno about the spinner? :$

Hi there

Here is a chart from Master Air Screw that has some usefull info on converting from 2 to 3 bladed props.

Even when using the chart you'll still need a watt meter to check that the power output is still with in the limits of the motor and ESC.

Thanks. Has anyone got this plane? I am still debating whether to get a 13.8 prop or a 14.7 prop. I do not have a watt meter to check. Someone who is good at this or knows this plane, can you rougly guess which one you would go for etc...
