Piping in.

After going over the wing engine charts I think they are resonable and I could compete with success with any two or four stroke combo and I may have to try a few different engines.

Only one thing I dissagree on is the minimum wing area for the Ys 1.15 as this was the wing area set up for the ys 1.10 when it replaced theYs.91.
The ys 1.15 was shoe horned in when they discontinued the YS 1.10. I know they didnt want to change anything at the time as YS was doing major changes to there engine line, but in my personal opinion that wing area should be now increcsed to fit the engine size and level the playing field.

From my calculations this wing area should be 535 sq inches for the Ys 1.15 So in essence using the wing area for the Ys 1.10 has given the larger engine an unfair advantage.

Yes I to would have to modify all my designs to fit this requirement and am completey fine with that.

So my suggestion is to at least consider and discuss this at the next meeting for maybe 2014.
