................In the last 10 years I have covered all my 1/2a planes with Ultracote. I goes on easier, has less chance of warping the wings, and is 3 to 4 times stronger so if my plane bounces around a bit in the car or on a less than perfect landing I don't have to fix holes. Is it heavier? Yes, but in weight measured in grams.

Given the size of most of the 1/2A planes, a little calculation on the area to be covered will show that covering weight is really fairly insignificant - in many cases, less than .5 oz. Like Bill posted, simply choosing a different battery pack or tank will usually make much more difference in weight than using a different covering.

I agree, but this model airplane is an area of ​​approximately =1.5m² = 16sqft

monokoteTOPQ0304 Weight = 0.2 oz / sq ft (61 g / m²) = 90grs=3,17oz.
ultracote Weight: 0.12 oz per square ft (36.6 g / m²). = 54.9 grs=1,94oz.
(90 -54.9) = 35.1 grams = 1.2 oz.

Good information here, thanks guys. I'll be posting more pics of progress. I've been on the road working...but will be home tomorrow. Perhaps I'll have a couple of hours to work on the plane over my next 3 days at home.

Finished framing up the first side.

Now on to the second.

Looking good, sirzepp. I have a question about the dihedral in the wing. I am working on a Kadetito also and on the plans I have there is no actual figure for the amount of dihedral. Measuring the angle of the dihedral brace with a protractor I get 9.5 degrees. Is there a figure on the plans you have?

well,
In my plan, the only existing picture is the one below.
It found a measure of 5 ° or 10 ° in total

I just used the dihedral brace to set up my wing...basically the TLAR method. We will see how she flies.

I expect you'll be OK with the dihedral, sirzepp. I checked a model design book I have, and for a trainer, an angle of 6-8 degrees was specified for 3 channel trainers. Think I'll go with 9 degrees. A little bit either way probably won't matter.

Fuse sides done:



Fuse assembly:



I made my first big screw up above (there have been a few little ones). I used a 1/4 inch ply firewall...for some reason my brain was convinced it was the right size (1/8")...I've had a lot on my mind lately and even though it looked too big...I installed it without reassessing. So now I can but a 30cc gasser on the front of my kadetito. Dear Lord, I think I'm going insane. Anyway, it shouldn't matter TOO much, I'll just move the battery back. The bummer is, I'm using an ultra light LiFe battery, and I just counteracted that weight savings...lol. But I am too lazy to fix it.

Mocked up:

Fuse is nearly complete. Just a few more things to do.



Still have to build the vertical stab and rudder, then it's time to prep and cover.

She looks great! This is about the time in every build that I "fly" her around the room making silly airplane noises when nobody is looking....

Got the fuselage sanded, installed the cowl, engine mount (and mocked up engine, obviously...which is where I started making airplane noises!). Hinged control surfaces and started mocking up servo placement. It's getting there, but the electronics installation and control rod routing is always where I bog down...I don't find it enjoyable at all. I'm looking forward to covering, but until I get the radio squared away I have to wait...UG.

Oops, I forgot to tell you, for the week your mother is here, I'm scheduled to be out of town on some contract work. Guess I'll just have to miss her visit, but I'll take the Kadet to have something to do in the evenings.

My mother-in-law is 81, doesn't mind 1/2A centerpieces, and occasionally goes up to the field with us to get a little stick time in on the buddy box. If your mother-in-law doesn't get the centerpiece thing, take her to a swap meet and trade her for a couple of good running TD's or something

You guys gave me a good laugh! Love that. Luckily my mom-in-law is an incredible woman...so glad to be married into their family.

Not sure she'd be down with 1/2A centerpieces, though...but a couple of TDs do sound nice.

She's up on her own legs now. Servos are installed, pushrods routed, engine mount ready...getting really close now...




Wheels are dubro ultra lite foams...front one is a bit smaller, but they are all kind of big because I want it to be able to fly off reasonably mowed grass. My dad doesn't have access to a formal field, so he'll be finding a place out in the boonies...and I want him to have all the options he possibly can.

It looks terrific. Over-sized wheels are excellent on grass, especially for small airplanes. It's amazing what will take off from a rough field if you just make the wheels big enough.

Looks great so far Sirzepp.
Can't tell from the picture, but you want to make sure that the landing gear setup keeps the wing level, or even just a tad down, otherwise they just keep bouncing and trying to take off again when you try to land them
