The Goldberg Jr. Skylark continues to draw attention...this time from my carving knife.

Yesterday afternoon, it's nose, fuse corners, and wing leading edges were victims of my deft wielding of a long-blade Exacto.  The thing is really starting to develop a personality. It's wing needs a little more trimming/sanding, and one of it's Tee Dee .020's tack-glued in place for inspiration.

Uncle Wayne's 51 year-old "Scout" control line stunter got some old-school hinge stitching to support it's ancient cloth elevator hinges.  This plane is still in good, flyable shape, with a healthy Cox "Golden Bee" on it's nose.

Wow, what a beauty! Timeless, classical construction method. Is it going to be RC? I assume so because of the dihedral. If my assumption is correct, how many channels will it have? Is simultaneous starting of two engines an issue?

Hey, THANK YOU!!!!

Yes, the Jr. Skylark will fly with a two-channel...elevator and rudder, and powered by two Tee Dee .020's. The Tee Dee's, with the new tank/mounts, will give the plane more power and a longer run. My friend Thomas, flew his with Pee Wee .020's at the 30th S.M.A.L.L. Fly-In a couple months ago (video below), and handled single engine flying with no problem.

Starting two (or more) engines CAN be an issue, but I've gotten a fair amount of experience with them...the key being to run them extensively on a stand before putting them on a plane.

Kim, the twin is cool. I wish I knew how to fly r/c. I built a beautiful model from the 80's that I purchased from Tower Hobbies. The kit was Italian made by Scorpio. My son flew it for the first time last year. I just need to be more persistent in going to the r/c field and just doing it more. They fly real big stuff and I don't know why they don't do smaller like you show. I think the cool factor alone makes it worthwhile. The Scout is a great little plane. My favorite from that series is the 1/2A Tom Tom. Just way cool planes and they do fly quite well. Ken

Very nice work Kim. Do you happen to have a guesstimate on final AUW of this little dual castor-slinger? Just curious as I have a JR Skylark that I do plan on flying next year and I believe I am up around 20 ounces without battery yet. Just curious. Thanks.

Hi Kim, here I am having a beer, I just arrived from my job and I am looking at your plane and progress! ... beautiful that model with the Tee Dee .020 !! I mean what color will you do ... congratulations friend!
Another question, I recently had problems with Rx Orange, tell me what RX do you use in your models with .010 / .020 / .049? Thank you Thumbs Up

Hey, don't really have a clue at this point, but will throw it on the scales once most of it's guts are loaded!

Hey Mauricio!

I intend to duplicate the box-art of the original model (photo below), with some additional wording or trim.  It's wing and stab will be covered with Monokote, while it's fuselage and fin will be painted with Brodak dope.

I've never used the Rx Orange, but have a new Spektrum Rx that I'll probably use in the Skylark.  I still fly on 72 mhz radios in several of my planes, and have collected micro Rx's for use with those.

Have a good day, friend!!!

Now that has been brought up i think the 72 MHZ Has more distance than the park fliers , i know when i was flying RC seemed the plane could bee out there a 1/2 mile ,, i have not flown the so called park flyer but says 300-400 ' i think of course in both directions that's a pretty good distance .
