Flight of The Sparrow and two new/old planes

I admit it.

I was a bit spooked to send up the rebuilt Sparrow after its masterful repairing at the hand of its builder; see my previous blog if you wish.

Original plans called for the reinstallation of a simple sport radio, but the elevator interfered with the newly rebuilt and extended rudder. On top of that, the pushrods were flexing excessively. In went a Hitec Optima receiver bound to a Hitec Flash 8 radio. I programmed both surfaces with as much throw as I could manage and tossed in a bit of exponential as well.

When it took off from the runway at the Coachella Valley Radio Control Club, it did so with sheer beauty. Plenty of power, but by no means is it a speed demon. It's much like flying a powered glider and I'm looking forward to taking it up again soon. It landed like a glider, too. I didn't think Anakin wanted to come down!

A visit to the field the next day came complete with what I thought were free models on the free stuff table, a table which netted me about 20 nine-gram servos and some servoless retract mechanisms a couple of weeks prior. Instead, these newest additions to the hangar were very low cost, sold by a friend of mine. Thirty bucks for the pair of old ParkZone models in the photo below. That little J-3 Cub, identical to the second R/C plane I ever owned and wore out, is in outstanding condition other than a bit of fading. It's since been cleaned up and some minor repairs have been made. It's almost like new and while the original Ni-Mh batteries are no longer available, I can fly it on some 800mAh 2S lipos I have on hand.

These once-plentiful models are no longer in production and parts are now made of genuine unobtanium. Or, to put it another way, ain't no parts out there.

Through a minor miracle, I still had a few small parts on hand including the missing cap on the wing retainer rod and a brand new bag of rubber bands. Of course, I'll check the CG. It'll be exceedingly interesting to revisit this wonderful little model now that I have considerably more flight time to my credit.

That P-51 is an interesting sort of transitional model, sporting now-common features like a brushless outrunner and a 1300mAh 3S lipo, but with an old school 27MHz FM radio running PCM. I may or may not fly it on that radio to see how it flies. A few parts are still available, but not many. The prop is flexible plastic and it might make way for an APC. The factory props are still available, by the way.

Happy New Year, everyone!
