Thanks again guys, I really appreciate your advice.
I put the order in for the 380 kv and a couple of 16x10 props of different material and weight to play with. Amp draw will be checked on the ground and in-flight too.
Re the 2100 mAh RX pack, I got that for my long term project (80" H9 Pawnee running nav & landing lights off the same pack) but thought about using it on the Angel. Until now

. I got a couple of small ones like suggested on order.
One last thing: is it worth trying the 2P configuration (if it fits) at all or is it bound to cause trouble? Would the extra weight make this plane less precise or harder to fly or both? Given our relatively windy weather I hoped the extra weight may help with stability.
After this I promise to stop being a PITA
