THANKS!!!!

P.9 of the manual states under "Warnings".

Gas Pitts - 40 is designed to be powered by 2C: 0.32 ; 4C: 0.52 engine

The two equate fairly well, so the instructions are basically calling for a .32 engine.

The LA .46 would be slightly more powerful than the .32 engine being called for... so it may be a VERY good match.

How does it fit in the cowl? Did you mount it inverted?

I used an LA .46 in a .32 Extra 330 and it rocks in this plane... I just wish that OS had not gone with the cheap bleed needle for the low end. As it is, I cannot lean the low end out enough... but the plane runs VERY reliably... w/NO deadsticks EVER from day one.
So now that you mention it, this may be a great combo!

Re: Bend

I held the two wings together to compare the strut attachment points and you are right.

When the two wings are held so that their centers align correctly there is a 1/2" variance (1 inch total) in the position of the strut mount points.

Now that you've mentioned this I'm going to fix this easily... how?

Take a small 1/2" wide 3" long strip of ply and shape it to go between the strut and the mount to off set the point.

Remove a bit of covering and expoxy the block directly to the wood of the wing.

Apply a small bit of Ultracoat and this "fix" will not be obtrusive. To really hide it, do it to the underside of the upper wing instead of on the lower wing.

A slightly longer bolt will be needed too. Not a biggie once this is pointed out as you have...


- Hey Nitrostaff are you aware of this issue? -


I would advise you to do the same with your "bent" struts. Don't leave them bent... this doesn't sound right.

Real Pitts DO have the struts at an angle though much like what the NP planes would have if the mount points were all properly angled.

I bet someone in the design department made a mistake and didn't want to loose their job....
