Status: offline 		Attached are 2 photos of my Goldberg Ranger 30 airplane. This is a 30 inches (760 mm) wingspan all balsa free flight powered by a Cox .020 Pee Wee. I constructed this some 20 years ago. It has sufficient room inside the fuselage to convert to RC using the modern micro servos, receivers and electric power, which AFAIK some have already done.

A tiled PDF of the Ranger 30 is available at:

Status: offline 		Major fond memories moment!

My first glow engine and kit was a Ranger 30 and Pee Wee .020, given to me by my dad when I was maybe 7 or 8. I freaked when I got it. Built it with some help from my older bro, and I recall it flew one big circle of the farmer's field across the road, not too high, the engine quit, and it came down somewhere in the woods never to be found again. Thinking about it, I probably have lost more Pee Wees than any other engine.

Ahhh..

Status: offline 		Reason why it is in good condition, is it never flew. I've spent the past two decades living in New Mexico. We rarely ever have a calm day. Good days are when winds are less than 15 MPH, which are hit or miss. We get gusts to over 50 MPH at least one day in each month (except lately, weird weather. One hasn't lived until he's learned to trim and fly single channel rudder only in 15 MPH winds.)

Perhaps one of these days I'll either convert this one or build another for small RC. The engine run on these is very short. About 1-1/2 minutes if using the Cox 4.5x2 prop, or 2-1/2 minutes if flying with a 5x4 prop. The new electric brushless motors, high capacity light weight LiPo's, and ultra-light RC gear make 1/4-A RC practical. (But if a retrofit, I'd retain the Cox Pee Wee for power.)

Status: offline 		Its easy enough to fit an external tank to a Pee Wee. When Joe Klause was still around and running Kustom Kraftsmanship he used to offer pre-drilled (for an external fuel line) Pee Wee tank bowls as an accessory item so you could still keep your original one unmodified.......
1/4A R/C doesn't have to be limited to the capacity of a 4cc Pee Wee tank............

Status: offline 		ffkiwi, I've already got one such modified Pee Wee engine. I did the modification my self some years ago. It is on my Ace R/C 1/2-A Stick. I have a Perfect CL wedge tank oriented with the wedge down for positive fuel pickup and extended flight time.

Sorry to hear you lose it, although seeing it in flight must have been amazing.

Remember when those engines were only a couple bucks at the hobby store? My first encounter with the Pee Wee was receiving it and a Scientific Hellcat stand-way-off-scale 18" span CL kit as a gift. I was 10 or 11 at the time, mid 1960's.

I don't recall the sticker price at the time but it was some single digit number with a ".95" at the end, I'm sure. $6.95? Back then I was a Jetex junkie too (actually anything my big brother fooled with was what I wanted to do), and went through a number of Atom 35's and whatnot. I was pretty young when I got a Scorpion 600, oooh that was a big deal. Successfully made snow sleds and cars with it, I think my only aircraft had wings too thin and they buzzed and fluttered to the ground. If only we had CA then.. waiting for Ambroid or Testors balsa model cement to dry was like.. well, it was like waiting for glue to dry, wasn't it?

Oh, I guess it is just perspective. At that age I would have been bent out of shape too.

I remember then the kits were lower in price. Scientific C/L kits were like under $2. The smaller Comet stick and tissue kits were $0.69 each, larger like Sparky a $1.25. Simplest gliders were $0.05, larger were $0.10; Skeeter rubber powered stick w/o wheels $0.15, Sleek Streak a little larger with wheels $0.25.

Yes, I remember buying those brands, also Comet balsa cement. Even though I wasn't 12 yet, one could buy these cements and paints. I didn't even know sniffing glue existed. We could buy firecrackers and sky rockets. You had to be 12 or older to buy M-80's and cherry bombs.

Nowadays I think society is too overprotective with children. Because we were able to do these things, we knew what the risks were and didn't do overly stupid stuff. It wasn't unusual for an 11 or 12 YO to be cutting the grass without parental supervision. We even had 5th and 6th grade JPO (Junior Police Officer) corps at our elementary school. Kids held stop signs to stop traffic and allow students to cross the street. Now only the adults do it.

Status: offline 		The Ranger 30 was my first powered plane. I used a B Bee .049 and control line.  I had to bug my parents for the kit, and then bug them again for the motor, that was the hardest part. Likely grade 7, about 1970?  It was hard to fly in the wind, up, down, up, down.  Then I went to mouse racers and 1/2A combats with the TD .049. Much better.  I had been thinking of copying one with depron or something for a leckie, it had a kind of different sheet wing with a perimeter doubler.

With a 1/4" border or so I gather, it is best printed out using a laser printer. My HP LaserJet P1006 can work with 1/4" borders set to no scale. Then use a glue stick to put it together, after trimming one edge to overlap the border on the other.

From that you should be able to make a foam Ranger 30.

Status: offline 		Scott, I can understand your noble attempt at RC. The Ranger 30 had a rather narrow fuselage and limited wing area, lack of lift (almost flat wing) to support 30 year old RC. With the Mattel, one would have to remove the receiver case, go with an Adams Baby Actuator and 100 mA nicad batteries to keep weight respectable. I had 2 of those Mattel units, wished I bought a 3rd. They were very cost effective and worked well. I lost 2 planes (Goldberg 1/2-A Skylane and Ace R/C Littlest Stick) with the system. (These were not radio problems. I lost the Skylane in the winds of the onset of a severe thunderstorm, the Littlest Stick with loss of engine power overflying an overgrown marsh.)

Now, it would be very easy because of the lightweight gear.

Just looking at the most recently discontinued Goldberg Eaglet 50" (1,270 mm) wingspan cabin trainer, I can see the Ranger roots in it. About the only thing different is the constant chord wings. One thing that separated Goldberg from the other trainers is having real windows in the cabin. That makes these kits worthwhile.

The Ranger 42 was not my first RC, maybe number 3? Lessee, (1) homebrew foam POS with Black Widow, single channel, (2) used Thermic 72 conversion, Black Widow on power pod, (3) Ranger 42?

Whatever.. but I remember I had a lot of fun with it - 2 channel Cox/Sanwa radio, Medallion .09, T-F 7-4 and a small Perfect tank (I can remember all that though.. ). I recall it was a smooth stable flier.

As my first kit and engine and as a birthday gift, I have some fond memories of the Ranger 30.

Status: offline 		Flew a Free flight Ranger 30 for years with Cox .020. As I recall it was more designed for the Pee Wee for F/F than the .049.
Was always careful to only put a few drops of fuel in the tanks with a syringe so as not to lose it to a long motor run.

I scored a Ranger 30 kit at a great price a few years ago and will eventually build it for micro electric 3 ch R/C, but not before I make some templates for a Depron foam version and more balsa ones as well....

Status: offline 		Oh yeah, it is overpowered for FF on a Babe Bee. The Pee Wee is a nice match. It is so cool these days to be able to outfit a small model with high quality micro radio gear that also happens to be affordable.

I recall one of the more terrifying FF models I had in those years was a Sterling Hornet C/L bipe on a Babe Bee. Launch and duck.. again, a good match for a Pee Wee. I finally got my hands on a kit for that too, a few years back due to the generosity of an RCU member. Now, there is something I should earmark for micro 2 or 3-channel. Hmm.

Status: offline 		I too built a Ranger 30 when I was a kid in grade school (1974?). I used a Cox .020 salvaged from a Cox ready to fly Red Baron biplane. The plane flew incredibly well FF. As I recall the engine was mounted offset to the right, so the plane would circle when it climbed (it worked), once the engine quit it went wherever the wind took it.

Sorry to hear of the infamous Figure Nine that did her in, a bit overpowered. The .049 was for CL, one then glued the wing to the fuselage.

I agree, with the latest light weight radio gear. It would also make an excellent electric powered plane.

I mentioned the link in my Post #11 above:

http://www.rcuniverse.com/forum/fb.asp?m=11308851

Go there and you will find a tiled PDF. Download, print it out, trim and paste together, voila! Build it to your heart's content (but we'll need build and flight reports).

No it was not a figure 9 it completed a loop, then the rubberband broke just past the bottom of the next so that was  more of figure Q.

No such thing, not till they do not have batteries, or batteries that charge in a minute and don't burn your model up.

The parts are 1/16th" balsa, except for the 1/8th" plywood engine firewall. Dihedral is 2-1/2" per wingtip for free flight, 1-1/2" for CL. Dowel is 1/8" hardwood. Fuselage is a simple box, once someone cut the parts out, should be able to figure it out if an experienced builder. I have the instructions, but don't have large enough a scanner. Your other option may be a similar same era kit plane, the Midwest Sniffer.
