That Eaglet 50 was for a long time one of my favored knock around planes it was powered the same as yours a old beat up K@B 20 which i still have. I built several of them but the best flyers of them was when the horizontal stab. was left squared off no rounded edges. the 20 would run a very long time on a four oz. tank at half throttle and the plane flew in all weather. my initial feeling for it were a piece of junk, Was I ever wrong, I still have a kit for it. (Ithink)

IMO the Eaglet is a continuation of Carl Goldberg's Ranger series of free flight and a foamy ARF R/C, except the wing is constant chord. Because it was considered a .20 sized trainer, has a longer tail moment (distance from wing to stabilizer), flights more or less would be of trainer quality. Built light and with a Schneurle .25 to .30 or hot .20 and a few changes to wing / stabilizer decalage and thrust line would probably make a nice sport plane when weather was windier, IMO. I could be wrong, but I think that the original one could even fly on single or two channel with a .09 or .15.
It wasn't until fairly recent that I purchased a K&B .20 Sportster. On-line auction seller claimed it to be in good condition. It was not, run hot with the aluminum piston's chrome severely worn through and aluminum badly scuffed. An on-line C/L friend offered me several parts engines for shipping and through that was able to restore it.
Explanations from the C/L community explained that the Sportsters were actually decent engines, but many users of the time did not know how to take care of it. The engine doesn't tolerate lean runs well. Being of AAC construction (high hardness aluminum cylinder with a chrome plated aluminum piston), it requires more oil with significant Castor. It does not do well with modern R/C fuel of 17% or 18% synthetic oil and 1% or 2% Castor for ABC engines. It runs well on fuels for the old iron piston with a steel sleeve engines. I bench ran it on fuel I use for my C/L's, 15% nitro R/C fuel with a pint of Castor added, upping oil to 25% with 10% as Castor.
The C/L community likes the Sportsters, because they will swing a larger prop with ease, one called it a poor man's 4-cycle. Thus, a well designed sport engine got a poor rap because modellers not understanding it, inadvertently abused it with lean runs, wrong props and fuel, and thus gained a bad reputation. Mecoa has repair parts for it, and still sells the .20 and .28.

Memories, memories,memories...... how would we ever manage without them. Way back in the early 80 when I started to fly R/C my favourite beater plane was a hand me down Goldberg Skylark with an old S.T 35 which I still have and which still runs quite good. That poor model took more abuse that anyone can imagine but it just kept coming back for more. I have the plans for it and promised myself that one day I would build another but time is running out as last month I celebrated my 76 th and the urge now is not as great as it was before.

Here is my shop today
OK, guys, I'm posting one pic to learn how to use advanced
OK, I did an edit to add more pics. I got even more. to add. I'll do an edit some time this week. Some of you guys probably bought some of the Kits I made and the Ducted Fan units, and the retracts. My company name was " SouthEast Model Products" I'll get more shop pics. and the pile of balsa I have. about $25,000 in 1990 prices.

Something is wrong with me.....I think I was raised during the depression or something....I keep saving 'things'....my last plane (Escapade MX) I had all this left over - and saved every bit of it! Then look at the EMPTY servo cases...and there is more stored somewhere else! I even have my AMA Cards back to the early 70's......I hope there is a cure other than death! And another thing...where did all those servos go????

GallopingGhostler, from what I see on your screen name I assume you used Galloping Ghost radios. I did a couple of the. The best one I had was the EK Logitrol 3 channel. I got it in 1967, I had a ball with it. The first time I use it on a Falcon 56, with an OS 19. The club president did the first flight for me to trim it out, because the wing had a warp in it. He flew into his own drivers side car window and broke it. AMA paid for it to be replaced.
I take it you did some escapement radios. All that was on 27 Mhz or Ham band if you had a Ham license. I wonder how many of the younger modelers could fly with an escapement, today.

Me and a couple of buddies started out in the early 60s. Next best thing to controline back then. The newest challenge. Escapements, then reeds then proportional. PCS was my first propo radio. It's been a long 80 yr ride/ flight since then, keeping up with the progress.
Into the gyro controlled type of planes and rcvrs, which open up many more doors. Makes me wonder what things will be like 10 or 20 yrs from now. I still have some of these radios and gear out in my garage.

20 years from now they will be able to build actual scale drones. There doing it now. Fighter planes with no pilots. So I guess that puts the few company's that make pilot figures and vacuum formed canopy's out of business

I was pricing out hardware. Just the simple stuff like 4-40, 2-56 6-32 etc. A small assortment box the size of a tacklebox is over $300! I buy up as much of the small stuff as I can. PIcked up a bunch of 4-40 nuts and bolts in Toledo, along with other items for $11. At least 1 item costs way more than that.

Sometimes you just run into a deal that's just too good to pass up. Several years ago I attended the Cape Coral R/C Club's annual fly-in and on Sunday afternoon on the final day of the meet a seller of regular hobby related odds and ends stuff discounted the items so low I was unable to pass up buying a whole bunch of small hardware items. After years of use I still have stuff left.
