HI, 1:3 scale Cmelak, from Airworld, with a Moki 215cc 5 cyl raidal. Just finished a month ago.

Big Nuts 181 · Jan 03, 2007, 05:03 AM

that is a gorgous model! I have been campaining my 40% 1-26 over the last couple of years now, and she's still doing big aero's. To tow her up and the following 40% 2-32 I have been building a 1-30 with a 140 king in the front for power, hopefully it won't take me too much longer!!

Rick, hope you're planning on bringing the new Cmelak and ASW-28 to the JR event this year, can't imagine a prettier picture than seeing the ASW towed by that yellow bent wing bird.

Looking good, I bet your 26 is a great flyer, how much does it weigh? and what servos did you use?

Making the side combings is much the same as I did on the 26 except I am making the plugs removable so I can mold them.

Since this model is bigger it's a little easier to work on and I wanted to keep the weight down so making molds for lighter parts made sence.

Later I will show the cocpit with the parts in place and primed.

Rick, your cockpit is looking super! How do you get from the foam formers that you clamp in place to the rough plugs? Is it simply a matter of globbing on body putty and sculpting it? If so, what gives the plugs some strength and keeps them from cracking?

Also, you mentioned using 3 oz cloth for the air scoop on my Cub. Where do you find this weight as the LHS don't seem to carry it?

Thanks,

Steve

The body filler is fairly hard when it cures. I did place a steel rod on the left side combing to bridge the thinner section where the flap a spoiler controls will be.

Try getting it from CST http://www.cstsales.com/index.html They have distrubutors all over. The have every thing you need except polyester resins, you can get that any marine store or mabe a hardware store. The also carry a wide variety of fiberglass and carbon plate, so you could use the idea that BN 181 referd to for your Cubs scoop.

Thanks Rick, will have to coordinate one of my CA business trips with Visalia, etc., so I can listen to your 215cc 5-cylinder wind up for a takeoff...gotta be a thrill!

High there Rick my first composite 1-26 (the one in the picture) came out a tad heavy at 45lb but much of that was "developmental" weight but the new model weighs in at 35 lb and a wing area of 25 1/2 square feet. Even so at that weight she is a floater on the slope with presence and on the flat the model can 'hang' around in an almost spookey manner. The servos I used were the Hitech 30kg for rudder and elevator, 12 kg on each aileron and tow release and 6kg on each airbrake. And to power it all 2 5 cell packs.

cheers Rossco

Rick, was at HKM today in Germany and Willi is setting up a big ASW-28 with a Schambeck up and go system. Very, very cool and there's such a small opening on the top of the fuselage. If you don't add one, surely Dan T. will!

Regards,

Steve

Hey! don't post this kind of message with out photos, are you nuts. Its like watching the superbowl with a tied game with 6 seconds to go and a field goal is about to be kicked and the satilite blows up! Is this the 40% Im building?

Rick

SteveR · Jan 29, 2007, 07:37 AM

Geeezzz, next time I'll remember to bring a camera along when I visit HKM! Of course it's the big ASW-28. The Schambeck is barely visible in that big fuse. I'll see if I can get HKM to send along some photos. Willi was setting up a new 28 while I was in the store and he demo'd the up and go system (without spinning the prop, of course). It is a very slick unit.

Hey sounds prety neet, I would love to build a 1/2 scale with the Schambeck.
I understand that it keeps the C/G problem at a minimum. Hows the weather over there? Sure do mis Germay.
