Engine too far to the left?
 

Hello!
I haven't flown my AT-40 trainer yet, but im finished building it.
I had some problems mounting the engine, becuase the mount was not completely straight(prebuilt mount).
I think it is only about 4-5 mm to the left. Will this make a big difference?

Now I am wondering whether my engine is mounted too far to the left. I have some pictures to show you how it is right now:


What do you think?

Thank you for all your help!

i wouldn't think this would make a big difference at all... maybe get someone elses opinion first...

That's perfect.

hitmanhit,

How does the plane balance out? Looking at the pics, I would say you're good to go, providing everything else checks out. Check your CG (center of gravity) according to the plans... check your control surfaces throws... get with an instructor, if using a field and/or club, and do a range check to ensure all is well with the radio equipment... fire it up and check the throttle transitioning, typically with the elevator behind your ankles, and let her fly!! True characteristics can only be found in flight.

Great!
I have checked everything else. The CG fits perfectly with an empty fuel-tank, and I have read that it is OK on a trainer.
Haven't been able to do a range test yet, but will do.

I don't have an instructur or any club with that offer since model airplanes isn't that popular here in norway.
But I've been practising alot on an electric trainer(a 4CH Cessna), and many hours with Realflight G4.5.

And now I am feeling pretty ready to take her in the air :D<br type="_moz"/>

Your engine is mounted exactly as it was meant to be. Your factory cut motor mount is intentionally built off center to the right (from behind the plane) to counter torque, propwash, etc. <div>
</div><div>I made a mistake once building a plane by glueing in the wooden motor mount upside down, giving the opposite than desired offset. It still flew wonderfully for weeks before I discovered my mistake. You have no worries.</div>

Your engine looks fine.

You may be surprised how many people fly in Norway or Europe for that matter. Have you looked up any members in the RCU search form? You could even put out a post asking for people in Norway. I think everyone with experience here would recommend someone with you on your first flight, to save you additional costs of a broken airplane. Either way good luck and have a fun time.

I have checked up every person alive with a model airplane in this town!
There are a few, but most of them are not organized in a club or anything, but I've been invited to meet up with them at their "private" airfield :)

So maybe I will take my maiden flight with them!

That's cool. If it means saving any frustrations, then it may be worth it.
Have fun,
