Brushless setup for PBY Catalina (Guanli)


I would like any suggestions for a higher powered brushless setup for my Guanli PBY Catalina. I want to use tri blade props for scale looks, but want more than scale power as I will be flying off lakes at 8000 ft elevation.

I've read that some people have put this pair of motors in the Catalina, but I'm not very knowledgeable on electric power systems and don't know if this combo would be a higher powered setup or not.

These are the specs.

Wingspan: 1380mm (54.3")
Length: 880mm (34.6")
Flying Weight: 780g (27.5 oz)
Drive System: Twin 370 carbon brush motor with gearbox
Speed Controller: 25A speed controller
Servo: 3x10g
Battery: 8.4 V 1000mah Ni-MH
Control system: 4 CH Multifunctional Radio Transmitter and Micro Receiver
Radio Control Range: > 1000 feet (300m)

I do know it is under powered with the brushed setup. It is also a floater.

Some info here about atlitude effect.

What battery are you going to use?

Thanks for the info.

I haven't decided on a particular battery and am open to suggestions.

I have heard the the Turingy motors may be a good fit. I'm looking at the 2209 from United Hobbies.

If you have any info on these motors and supplier, I would appreciate it.
