Hi there,

What prop do you use on YS-170 DZ and Integral? I have currently available an ΑPC 17x12 and a Mejslik 18x10. Which one would you recommend for break in during first flights? Do you use an air restrictor and what is its main purpose really? On my YS engines I always use the Tetra air filter, is that a common practice? Also the std Tetra 580cc tank what flight duration will give me for such engine?

A final question on the spinner, I need a spinner for Integral but I think the final choice will depend on CG etc. I would like to get a TruTurn to be honest but noticed that top guys such as Ola and Matt use the one by Phillipe Marquet. would you use a std plastic spinner by Great Planes with metal backplate (this is similar to MK) with such an engine?

Thanks in advance,
Nikos
