The plane is not light- probably around 8.5 lb or a bit less. 8800 with the 15 x 6 doesn't really move it very well and the lower RPM with the 14 x 8 seems to be more of a struggle. I have a 14 x 8 APC that is worth a try. The 14 x 8 MAS certainly wasn't great.

I guess I have some stuff to try this weekend. Props, fuel, plug and I think I'll try leaning the low end just a bit.
