Thank you John. That method of making a canopy is so much easier than another method I read about that required an oven and involved pulling a flat sheet of plastic down over the plug clamped in a vise, with a window of opportunity of about 5 seconds. That method could also leave foul odors in the oven. I also don't have a vise in the kitchen or an oven in the garage.

I remember back when I was building jet style planes but never tried forming my own canopy. I would buy large RC canopies and cut out the part that I needed. It was OK, but I never ended up with a perfect match.

Yes Dick, it is an easy method. I learned it from an article some time back. Until I tried it, I always thought that it was too difficult to make my own canopies.

Glad to pass it along.

FYI on the incidence meters,
I have one of the laser instruments, I am totally unsatisfied with it. It is not very well engineered. The laser does not want to align with the scale effectivly which makes it impossible to get a reading from it.
I am looking to purchase another meter style meter and my laser one is in the bottom , at the back, of the furthest drawer in my shop area....
Its a great idea, but unfortunatly it seems not enough energy was expended in design and manufacturing to make the lase toole effective...
my experience,, yours may differ.

Regarding the two major brands of incidence meters, I recall comparing the accuracy claims for both. The gravity powered Robart unit, as I recall, is supposed to be twice as accurate, and doesn't need batteries, a plus. The second brand is/was Great Planes, it's a Laser unit, but I've not been able to find them at Tower to confirm the accuracy claims. It must be .25 degrees, because the Robart claim is .125 degrees. In addition to what John says, you can put one on the root chord and then each wingtip and check for warps. This doesn't work so good when the flaps are installed, but if you make the flaps and elevators removable, all is well, all the time.

Here's a nice tutorial on the use and functions of the Robart unit.

Any flights on the twin yet John?

John Miller · « **Reply #105 on:** December 15, 2009, 06:51:32 PM »

Not yet. It's too cold and 5 inches of snow on the field. I'm anxious to get it airborne, but have to wait.

Sigh...........

Hey John, put it on skis.

HAPPY NEW YEAR

John Miller · « **Reply #108 on:** December 29, 2009, 12:16:27 PM »

Ski's. We don' need no steenking ski's

By the time I get bundled up to survive the cold, I can't move my arm or wrist. If I fall down, I have to lie there until someone takes pity and helps me up.

I'm thinking of taking it to Tucson for the SW Regionals next month.

What's the latest on this one John? Any flights yet?

John Miller · « **Reply #110 on:** February 24, 2010, 09:16:12 AM »

I'm fitting new cowls. I fitted the originals before I had the venturiis made. The cowls had to have so much material removed to accept the venturiis that they were too weak, and would easily break.

It's been a slow progress, as I've had several drawings that must be finished before VSC. Combined with more work at my job, it's made time a rarity.

Mark Scarborough · « **Reply #111 on:** February 24, 2010, 09:29:52 AM »

WORK, like for real get paid work,, wow thats a GOOD thing John,,
well except for the interfering with important things like models,,;)

wwwarbird · « **Reply #112 on:** February 28, 2010, 09:27:38 PM »

I hear ya, work keeps getting in the way of my modeling too. I guess that's a good thing these days. Have fun at VSC, I'll be at, uh, work.

John Miller · « **Reply #113 on:** March 24, 2010, 09:39:51 AM »

Since I was unable to attend VSC this year, I decided to wrap up some projects. Of course, I'd made the changes, and repowered the Torino for VSC, so the bench was clear.

A month or so ago I got the Magnum .15's back from Glen Dye. He'd made me some great post style venturiis. I like using a post in the venturii esp. after Frank MacMillians (sp) article in Stunt News some years ago. His article showed that a post is slightly better than either of the other 2 types of fuel delivery. I also like the fact that the fuel line goes straight into the NVA, and the needle is opposite of the muffler.

After mounting one of the engines to fit the cowl, I found that I had a serious problem as the needle cutout would seriously compromise the strength of the cowl.

I set it aside while I worked on the Torino, but now that project was finished. The bench was clear. I needed to figure a way of modifying the existing cowls, or build a new pair. Being basically prone to the easiest solution, (No, I'm not lazy, I'm not I'm not, I'm not.) I figured that since the plane was supposed to be a German war plane, with roots to the designs from WW2 Messerscmidts, I thought a pair of radiators similar to the Me 109's might work.

I didn't like them until after I painted them and placed them in their proper locations. They looked right, so I went with them.

I had to peel off all the self adherring decals. They curled up around the edges when I tried to spray clear over them. What a mess, but the good part was that only a small amount of paint lifted, and most of that was limited to areas that will be under the new markings.

So I gave it a couple of clear coats which was interesting. Areas of the lighter splinter camo paint got a little blotchy, but it still looked right for a wartime paint job. Weathered and all.

New markings went on today, and here it is, ready for first flights, perhaps this Sunday if the weather holds.

I hope you enjoy the pictures, and the design.

John,
Looks like that will do it. Looking forward to flight reports.

Mark Scarborough · « **Reply #115 on:** March 24, 2010, 10:25:00 AM »

John, John, JOhn,
them are some whimpy little cannons you got mounted there, I hope at the least they shoot depleted uranium rounds! I mean after all the Germans were into BIG bore guns,,
Looking forward to hearing how she flies,, pretty cool concept,,
are you coming to the regionals this year?

John Miller · « **Reply #116 on:** March 24, 2010, 10:41:11 AM »

Mark, I hope to be at the Regionals this year, if I can get me a set of industrial grade shades to help offset the glow of your sweet Avenger.

What do you mean wimpy/ A pair of 11 mm machine guns. a pair of 20mm cannons, and for the coup d gras, a pair of 37mm cannons. Sheesh, bigger would tear the plane apart....

Shultzie · « **Reply #117 on:** March 24, 2010, 11:07:54 AM »

WOW!
LOOK WHAT I FOUND ON S-----STUNT this morning?
BEEEUUUTIFUL WORK, JOH N!!!

Mark Scarborough · « **Reply #118 on:** March 24, 2010, 11:09:33 AM »

John, Pat may MAY have his SPitfire ready for the regionals, at the least he will have a Mustang, and maybe a bearcat, so we of the Axis powers need to be prepared for the onslaught. My 109 is in finishing stages now,, so it will be on hand to help I hope

John Miller · « **Reply #119 on:** March 24, 2010, 04:18:25 PM »

Well, I hope you can finish up the 109 in time. I'm looking forward to seeing it. I might be able to bring additional reinforcements. Gordy's got his Tony flying real well on a Stalker .81RE. Let's see, that would be 3 Axis planes to Pat's 1,,, hmmmmm.
