I just finished my Extra 330L and i used a Roto 35vi(gas) Engine!!
The engine's manual isn,t very good!!It hasn't enough details for break in and what kind of props i can use...
What prop do you recomend me for break in?I'm thinking a 18X10 or 18X10 menz..Is it to little or good for break in?

How should i do the break in?
How do you break in your gas engines???
(It has a walbro carb)
Please help me...
Thank you
