You are running a GRP prop on that. How good an idea is that?

Nothing wrong with APC prop. Some may be slower to spool up than carbon or wood but they have very good airfoils and many times far superior performance over wood.
They do need to correct the reverse starting, change the start timing or something. My larger glow engines used to do that when flooded so I'd flood them and bounce'em off compression backwards and they'd start fine every time.
X2 on the APC props. Lot's of guys running them without issue. Much sturdier than wood if flying off a rough grass field. My only cautions would be regarding balance (DO IT!!!), and careful removal of flashing/sharp leading edges.
Re: starting backwards, that used to be SOP on the big Supertigers! They'd start very easily, but opposite of the way they were flipped almost every time! So, didn't take many long to learn to flip them backwards. You didn't even have to go all the way through the compression stroke....
