Truth be told it's not as good as the photos make it out to be, but from 5 feet away it's decent enough! :-). Yeah, I'm glad the toughest part is over. Once I get the wing done I can focus on something other than painting at least :-)

cheers,
Ken
It takes at least 10 feet to make my airplanes look really good! ;-)

I agree, you've made a beauty of her!

Just to recap the method, you painted Nelson paint over Solartex using a bristle brush, right? I know it was a lot of work, but compared to what I've been doing, spraying dope, it seems so much better. I was constantly trying to save on solvent, but then having to use a lot to clean every nook and cranny in the spray gun, getting on my hands, breathing it, paying for it. Your method sounds so much better, and now we know it can look terrific too! Thanks for these posts; keep up the great work!

One more thing: will you be able to tell us the weight gain from the paint?

Thanks again.

Thanks Dave, Jim!

Jim, yeah, it was brushed on System 3 paint from Nelson's, but I did use a foam brush for the wing just because I didn't have a good width bristle brush to use for that large surface, but I got better using the foam brush with practice. I do like the non-toxic aspect of this paint...
I'm afraid I didn't weigh the airframe prior to painting so I'm not sure how much was added, but I'll get a ready to fly weight when she's done...

cheers!

Thanks Ken, I usually forget to do the "before" weigh too, just hoping maybe you did it. Will be interested in the final weight and test flight. Jim

Guess what got painted? These sudden bouts of productivity are hilarious...



P.S. I wet sanded the ABS cowl with 320 sandpaper, which was perfect to remove the gloss and create a suitable surface for the paint.

Hard to believe such nice results with a brush; looks really great; looking forward to completed airplane pics.

Hi guys,

I got quite a bit done this week. The plane is pretty much ready except for the placement of the RX, battery, and switch! I did weigh it all though, just excluding the RX, and it turned out to be 1oz shy of 5lbs (i.e. 4lbs, 15oz). So with a couple of ounces for the RX it'll just be about 5lbs. I'm frankly amazed! Using the Solartex and painting over it didn't add all that much weight it seems (either that or it was a fairly light airframe before covering). So that's all good.

Enjoy the pics...just gotta install the receiver, battery and switch, then balance, and finally run in the engine. I didn't expect the build to take quite this long (about a year since starting) but it was a wonderful experience all-in-all. Thanks everyone for following along and the tips and encouragement along the way!



Cheers,
Ken

That's really nice work Ken. I've been building models for a long time and that Kadet of yours is well built and finished. Congratulations to you. Very nice job.

Thanks all for the kind comments...

I found that to balance in the middle of the CG range indicated, the RX battery has to go just under the fuel tank, and the RX itself and switch can be right in the middle of the radio compartment. I haven't installed the switch yet but I wanted to show how I mounted the RX.

Continuing in the spirit of trying new things (to me) in this build, I recalled a method I saw on Jim John's old pattern website from the late 1990's - I'd never mounted a receiver this way before but somehow remembered the concept and gave it a go...it works great! I fashioned two "H" brackets using scrap from the kit box, and with 4 rubber bands mounted as shown in the picture below. It's very lightweight, secure, offers excellent vibration damping, and is very easy to access the RX.



Cheers,
Ken

That is a neat may too mount the receiver and the rubberbands are easily replaced too.

Yes, that looks like a good method. My one question is, won't it work its way forward on each landing, and what happens in a crash?

A friend tried a gyro on a four stroke powered plane and the gyro failed due to vibration. Maybe this method would prevent that.

Personally, I'd rather mount the rx solidly with a piece of foam rubber wrapped around it.

If this system will hold the RX in extreme manuvers I don't see why it wouldn't hold in a crash provided there was no structural damage in the area of the "H" brackets. Then again if the structure was damaged that far back it wouldn't matter how you mounted it. It seems to me if the Gyro was held at the correct level it should work.

They don't recommend you do that with 2.4 Ghz Receivers because it interferes with the antenna orientation requirements.

I do it all the time and provide mounted straws that orientate the antenna leads
