Prop direction on a twin

[chickenhawk]

Just can't seem to wrap my head around this one.
When facing the front of the plane--motors mounted to front of wing in pull. Motor on the right turns in CCW and motor on left turns CW. But with motors behind the wing in a pusher ( still facing front of plane) the right hand motor now turns CW and the left hand motor turns CCW??????????????????????
Does this seam right? What I really need to know when facing the front of the plane with motors in pusher, what way are the motors to turn? LOL

I don’t think it matters as long as the motors are spinning opposite directions (one CW one CCW).
(you reverse motor direction by switching any 2 of the 3 plugs between the motor and esc)
Also the ~numbers side of the props~ should always face the front of the plane regardless of how the motors are oriented.
Once you’ve done all that, if your plane pushes backwards instead of forwards, swap the 2 propellers.

I hope this answers your question…

I did not know about mounting the numbers towards the front of the plane. First twin must less a pusher.

As long as one motor doesn't fail in flight, which motor turns ccw/cw doesn't matter,
BUT, in theory, if you have the motors turning the props top-inward toward the fuselage, if a motor fails, the remaining motor has a better chance of flying the plane. (Unless you use differential thrust and no rudder)
If your motors are on a Y harness, ccw/cw won't really matter. Be sure the prop numbers are forward, and thrust is to the rear of the plane.

Yes using a Y harness, and using a rudder. See did learn something, did not know on a pusher setup you put prop numbers facing to front of plane.

numbers ALWAYS face the direction of travel.

It can get pretty hairy when you have a twin...there can be different directional props you can do too. Look up info/videos on the FT Seaduck. I believe with my configuration on the FT Seaduck they are counter rotating and spin inwards toward the fuse. You don't have to do it this way, but it looks awesome. Works great too. And yeah as @mrjdstewart said, numbers must face the direction of travel.

I'm pretty sure from my exp (which is not much compared to others whose is like 20 years while mine is 2)
I f you're sitting in the cockpit and looking front the left handside will spin cw and right ccw ( this is for puller)
the left handside will spin ccw and right cw ( this is for pusher)
