COOL!! Since it's a Chipmunk wing I think you should be OK at anything under 50 ounces. it's a good wing and a lot of it. There is a whole lumber yard in that fuselage!! I think the built up wing helps you A foamy might be a bit heavier. I'll have to dig out the article and reread it to see what his claimed finished weight was.

Dan you are right a lot of wood.   I used the best of it I have but maybe could have thinned things down a little more internally like 3/32 sides instead of 1/8.  Maybe mold the top instead of a block and boy the landing gear is three big hunks of wire.   

Hi Dave.  OS .46 LA-S.  Too heavy is too heavy.  But just had to fly it. Once. 

That looks great Dave!! Are you going to put the missiles on it as well?

Thought I’d throw up one more photo.   The machine just needs a little clear dope and I’ll call it done.   Hope to test fly next week and get it trimmed before snow flies and the flying weather is gone.

Dave

Nice work

Paul thank you.

Dave

No Ty it does not.  Was it supposed to?   Didn't recall anything about that on the plans.

Dave

Thanks Matt.   I did go ahead with the sidewinders.  We are now just over 50 ounces total with everything so I will just lay some airbrush clear over the ink and lettering and call it good.

Dave

Thanks Ty.   I ended up with a white plastic spinner on it for now which has a better shape.   Final ready to fly weight is 51.8 ounces.   As usual a little more than planned but the AeroTiger should have enough grunt.   It weighs in at 7.7 ounces (no muffler) which is about an ounce more than the Fox would have been with extension shaft.   Sure enough it appears to balance just a touch noseheavy I'm guessing.    I'll fly it this way to start and see where it goes.  I wish I knew what the original airplane weighed but I can't imagine it was actually much lighter with the foam wing and thicker finish.  I hope this one will be VSC bound....

Dave

Thanks Wayne.   The airplane is already undergoing an engine change.  I took it out Saturday morning for a test flight.  It was really too windy but I wasn't gifted great patience.   As it turned out I couldn't keep the AeroTiger lit long enough to launch.   I changed the plugs a couple times but guess I don't have anything hot enough to do the job.   I sort of hated building an airplane where I have no back up engines anyway.  So it is getting retrofit with a Merco .40.  It only weighs 1/2 ounce more and easily swings 11" props if need be and will give me more power.   I also have a couple of these for the future.
Since I built this specifically for Super 70s and N30 I really wouldn't want to stray very far from the original design.   

Dave

I got out this afternoon and put up one windy test flight.  I think we have a winner!   The Merco .40 ran very well in a gentle 4-2 on a Top Flight 11-6, and feels like the right type and amount of power.  The wings appeared to be level and the airplane seemed to be grooving pretty well upright and inverted.  To me this puts the airplane in the 'keeper' category as the rest will be things that normal trim will fix.  I felt the airplane would be too nose heavy but in flight it didn't seem so.   I had the readout adjuster fully forward and It needs to go more forward.   When I got back home a little work with the Dremel allowed me to move it up more.   The other main issue was unequal inside and outside turns.   That makes sense and is the reverse of an airplane with low wings,  with or without dihedral.   This anhedral wing turns faster outside than inside.  I have adjusted in a notch of handle bias which should be enough to even out the feel.  Once the engine cut the airplane basically landed itself without a bounce.  Now I just need a little more flying weather......

Hey Thanks Jake.   It sort of worked out that way.   

Dave

Thank You Mark!
