Here is my queston to you guys. I want to convert my Do-335 arrow to electric. I want to do either the rear motor electric or both front a nd rear. The rear motor is an OS 60 and the front is the OS 150. What wouldbe and equivalent size electric for both thefront and rear?

rear motor AXI 4130/16
front motor AXI 5330/18

Gonsos, thanks for the reply. Do these guys ahave a wweb site to check them out? I am considering a 4045z 10 to replace the os-60

The Hyperion motor 4045 10 is more like a 91 and the Axi 413016 like a 60.The Hyperion one weight 144gr more and needs more serial batteries. If the DO-335 needs to be more tail heavy I would go for the Z40 but I think it is enough with the 413016.

The Hyperion Z40 25-16 is similar as the AXI 413016

1 horsepower equals (very close) 750 watts.

I believe this is a pic of a Do 335.
But I have never read up on the original plane's performance and purpose.
