Any tips before I start mine?
Unfortunately, due to the lockdowns, I have not flown it yet. I built an earlier one after the plan was published (1961!), which flew well. There are a couple of small errors on the plan re location of joiners and wing section at the root, as shown on the fuselage, no big deal. It is a good, sound design. I did not use the swinging trigger for the autorudder,as that tends to eject the towring, and used a KSB timer.

Here is my latest, a Peck P51 Mustang. Thank you to Crabby who supplied me with a copy of the plan, I have no idea where the original went I probably screwed it up when I wrecked the first attempt at this one about 30 years ago. Fuselage is modified to 1/16" square cause I cannot work with 20th. Its taken me forever to finish this one, dont know why but we are all done now

Lovely work on the Mustang VM. The covering efforts I see here are quite intimidating Smiley

Not sure of weights, scales decided to not work ridiculous isnt it I mean they are only 30 years old!! looks like I will have to look at the great god amazon for a new set. Not only the covering, some of the masterpieces on here make me think long and hard before I post anything

Or an FW-190... 

A little nostalgic fun.  The Guillows #502 FW-190 was the first stick and tissue model I built, back in the mid-70s as a kid.  A gentleman that works at our new flying field gave me one with the fuselage built during our December flying session - he felt the sticks were too small for him to enjoy building the rest of it.  I started on it the day after Christmas and truly enjoyed the build - used the kit wood, tweaked things where I felt like it and didn't worry too much about what it'd weigh or whether it'd be competitive.  I printed flight simulator graphics on the kit tissue and experimented with chalking the back of that with white PanPastel - I think it gave a much better look than what I got from raw printed tissue on my Tempest.  I even found the cowl blisters from my original 1970s build (I'm such a pathetic pack-rat) and used them on the model.

It's quite portly at 32g without motor.  Saturday I loaded 8g (2x24" loops 1/8") of rubber into it and took it out to play - was pleasantly surprised with how it flew despite being shall we say kind of dense.  Still needs more trimming but let's just say it looks and flies a bit better than the one I built back in the 20th century...

Wonderful! The chalk on the back of the printed tissue really works, looks almost like an airbrushed finish.

That kit was my first on returning to the hobby after over a decade.  Bought it at a local store.  Used all the kit wood, rubber, tissue and prop.  Never weighed it.  Painted it with Aeroglos dope.  It was a total dog.  Then discovered Model Builder Magazine, Peanut Scale, and the FAC.

Even the weathering is included on the printed tissue skins Shocked. Impressive effort Mike and the chalking certainly seems effective.

Watching the flights - I think portly or otherwise it appears to have lots of potential. The zoom at the end of the power run appears to me to be a combination of a bit too much decalage and the resultant extra required down thrust.

I would suggest that you retrim the glide with slightly less decalage and a slightly further aft CG and reduce the down thrust to a minimum.

Happy trimming.

My Antoinette certainly isn’t a new creation, but a slightly tatty old one. However I have just revamped it whilst my building board was clear. Main job was removing the rather heavy radiators which were made of shirring elastic wrapped around frames and painted a copper colour. The new ones are just paper, and a more accurate greyish colour. This exchange has knocked about 5g off the all up weight. I’ve also re-rigged it all with thread, as all of the original grey elastic rigging had perished and broken, and I’ve patched the worst of the splits in the wing tissue too. If I can just get old Hubert flying again I can pitch him against my new Bleriot and re-create the Channel race all over again!

Mike:
That is really awesome. The tissue is fantastic, well done!

I notice some of the structural changes ... balsa infill on the nose, some details on the leading edge of the canopy/cockpit, and the vertical stabilizer.

Are there any other hidden alterations?

I have an older version of that kit that's been sitting around. I'd like to blow it up to 2x or thereabouts, but there are a number of details on the plan that had left me dissatisfied with what I'll call the "basic accuracy" of the design (the biggest, as I recall, had to do with the relative location of the cockpit to the wing). Looking at your beauty, I'll have to reassess my thoughts on that, as it appears I was wrong (not the first time, nor will it be the last).

That's some super work! I love it.

Dave

Thanks for the kind words guys - I really enjoyed the build and am pleased with the result.

John

John, I did a post-trimming cg and incidence check this morning and think your diagnosis is on the right track.  It's got about 2 deg decalage as-flown and the cg is ~1/32-1/16"" ahead of the McCombs-calculated target.  The model has a bit of differential washout, with the right wing having about .5deg more than the left (that's probably not helping me much...).  I don't have an easy way to measure the downthrust with the prop on the model, but there's a lot.  Right thrust looks reasonable.  I'll move the CG back about 1/32" and even out the washout, then next calm morning that I can get out I'll re-trim the glide.

Dave

Thanks Dave.  The biggest change I made was the nose - cut some rings with a hole saw and framed up the cowl for a proper noseblock, and sheeted it back to former B2 (approximately where the real aircraft's cowl ended).  Did a bit of cosmetic infill to represent exhausts and the cowl gun ports and covers.  I also cut down former B4 and added a few bits of 1/32" sheet to get the cockpit area closer to scale.  Only other significant changes were to fatten up the fin, add supports for the wing guns and fill in a bit around the exhaust port area behind the cowl under the wing.  I used the kit's vacuformed windscreen but cut off the canopy and replaced it with one made from paper and thin plastic as I couldn't stand the seam in the middle of the canopy (saved some weight there too).  I sanded the sides of the assembled fuselage very aggressively to narrow it down a bit aft of the exhausts.

The basic outline of the kit isn't bad at all - see attached overlay of the -A3 three-view from the Squadron In-Action book on the Guillows plan.  You are correct that the cockpit-wing relationship is off - the windscreen is too far forward and the wing is mounted a bit too far aft with too little taper in the leading edge.  I moved the windscreen back about 1/4" and decided to live with the wing shape and location.  To me it gets enough of the look right to be satisfying.

If the shape discrepancies are too distracting, consider building Mike Midkiff's 25" span FW-190.  Rich Adams has done one that looks spectacular and flies very well.

Mike:
Nice comparison. It could've been the details around the cockpit, as well as the engine cowl.

Thanks for the suggestion on the Midkiff plan. Will take a look.

I do have Al Lidberg's Ta-152 plan, but that's really an entirely different beast.

That is actually less than I would have expected and probably what I would have liked. Strange!

Good luck with the trimming.
