I have a simular setup in my Pizazz. I have the Irvine 53 with a 12.25x3.75 APC. I tach'd it today and it was turn'n12700 on 10% omega I should have put better servos in it but I use futaba 3003 & 148's.
I like the Pizazz. Mine really flies good. probably the best hovering plane I own right now. Maybe its them Irvines. I have 3 46's , 2 53's and 1 25.
I will say this about the hardware in the kit, it sucks especially the hinges
I 'd like to get another pizazz, strip the covering off it, cut the fuse sides off around the eng compartment, re-do the firewall with the motor on it sideways, and then fare it in with balsa. Cover it in transparent green. Might have to do it this summer.....Gator
