HI there!
I am considering building a twin engine aircraft, Have Warbird experience, scratch build YAK9, LAG7 and IL2 all were around the 72 - 74 inch wing span and used a SAITO 120 FS engine. I am considering building (Scratch building) a Pe-2 and was thinking building a "HAK" first to get some twin time before I go to my scale project.

So the question is, for specs like:
W/S= 70 - 74 inch
Weight -11 - 13 lbs
Wing area 800 - 1100 sq inch

What type of engine will give good performance? I know that this is hard to determine, fuselage, wing selection etch, etch However I assume that a single engine develops 10 lbs of thrust with 2.1 horsepower, then in order to get the same performance from 2 engines would one devied the horsepower in 2? and select 2 engines? that add up to the original single engine rating??

Any tips are appreciated.

Kindly Regards

Erick!
