Hello all. I am having trouble picking the right prop for my pattern plane. The engine is a YS 110 that pulls like a horse. The model is very slippery and on downlines it speeds up a little too much for my liking. I've cut back from a 14x12 to a 15x10 and like the overall speed, except for downlines still. Is there any other prop I could try for slower downlines? A I have a 16x8 but having flown a similar model with that prop in the past I think overall it will be too slow.
Any thoughts? Thanks and happy holidays.

What model?

Hi
I use 16x8 on an OS 120AX (stock muffler) powered Epsilon 90, for flying in winter. I find the speed more than sufficient. I am quite sure that the YS 110 will perform similary.
Anyway if you have one, try it. If you like it, use it. If not ...

Whats the speed like in the wind ola? The 14x12 was pretty good in the wind, so we'll see how the 15x10 does.

Hi again
Since I use this model for flying in winter (real cold winter), I prefer to fly in low-wind conditions only. But compared to my other models used for competition I do not feel that I lack any speed. What I notice is that the Epsilon gains quite a lot of speed going down, even with 16x8. This may be because I am now used to electrics and their very good braking.
Generally it's very important to have a really low idle to get proper downline braking.

I have been flying the new Focus Sport that last couple of days. The model performs well with the 110S ona 15-10 and Cool power 30% heli. Temps have been in the 60's and nearly no wind.

The model is 8.5lbs and has tremendous power to weight. It does really well with this combo.
