A little side project...
« on: January 10, 2017, 08:47:23 PM »
 Here we have the "JAP ZERO" LL~

 I found this little "gem" on Ebay recently, a whole fourteen bucks I think it was. It was partially started as shown, and complete except for the L/E and T/E pieces. Oh, the controls and L/G were missing too. The decals were there but they're toast. I've sourced some fresh stock for the L/E and T/E and I started in on building up the L/E tonight. I've got a few ideas in store for it and at this point I'm thinking it's going to end up with a Medallion .09 on the nose, we'll see. Anyway, I'm planning on piddling around on this one off and on while also working on the 'Hutch P-38...

Couldn't quite tell if it said 36" or 38" span, but I don't think it'll keep up with your P-38 unless you put at least a .25 in it, and probably not even then. Got a good .35 Combat engine in the drawer?  y1 Steve

 Steve,

 Per the box art it's only 28" span and calls for .09 to .19 power. Since I don't have the original L/E or T/E, and the plans don't give the info, I have to take a guess at the rib spacing. After looking things over I've settled on 2-1/2" inch spacing, which will end up giving me about a 30 to 32" wing including the tips when finished. There's not much chord either so it's still going to be a small wing, I bet a Norvel .074 would fly this thing just fine. If I decide to stick with the Medallion .09 it's going to be pretty crazy.

 Got the wing framed up tonite..

 First was laying out some blue tape onto the benchtop then drawing out a "plan" on it for the wing. I then marked and cut the rib notches in the L/E and T/E sections. After all the parts were ready to go I glued some 3/4" square blocks onto the tape with CA to create an elevated "jig". Lastly it was to just align and pin down the L/E and T/E securely to the "jig" blocks, then fit and install the ribs. Tip rib to tip rib is now 30".  ;D

Ok, I read it better today than previously. A .21FP should work fine...  LL~ Steve

 Hmm, I do have a brand new FP .20 sitting on the shelf, but nope. I've never had one, but I've always thought the Conquest .15 was a pretty cool engine. VD~

 Actually, I've now committed to the Medallion .09. I cut out a new fuselage today with the proper beam spacing for it, the old original mounts were about a 1/4" too wide.

 Tonight I flipped the wing over, pinned it back down, and made a new platform for the bellcrank. Next I widened the existing notches for the mount just a bit because I made the platform about 1/4" wider (front to rear) than the original. With these changes it now sandwiches between the rib and the newly added bottom spar, ending up flush with the L/E of the spar. The way it all worked out it now allows the whole wing center section to be glued together creating a solid unit, good and sturdy for the bellcrank mount. Oh yeah, I forgot to mention that the wing didn't have any spars as designed, I filed notches and added them, 1/8"x1/4".

 After all that I set a few of the big pieces together to get an initial look at things. I think it even kind of looks like a Zero.  ;D

Who was the kit manufacturer? The plans look like they could be from Sterling.

 Larry,

 Sorry I never got back to you here, been away from this one for a while. The kit box says Master Modelcraft from New York, NY. I don't know anything about that company but to me the kit seems a lot like the older Japanese kits, maybe there was a connection?

  I've been looking at the half-built Zero sitting in my shop all this time and now that the P-38 is finally done I'd like to finish this little one up, should be a hoot!

Any chance patterns have been made of all parts? This looks like a pretty cool step up from 1/2A.

Thanks in advance,

 Sorry no patterns, a design like this would be very easy to draw up from scratch though.
