It was faded, dented, and rusty. So I went to the Army-Navy surplus store and bought some genuine Army camo spray paints and just did a free hand camo paint job. Well, it did stand out, lol...

I have been working on a new airplane project. It is a 3D printed Ercoupe. It is designed by Lofted Aero and the STL files, G-Code files, and really nice building instruction book are included in the purchase price.

It has been a bit of a challenge, as my printer has not made every part exactly 100% perfect. So when it came time to glue the parts together, there were some gaps. Also had a few under-extrusion issues. Not enough to prevent it from being built though.

This modern technology still continues to amaze me. I am having a lot of fun learning the 3D printing hobby.

In 1974, I taught myself how to fly RC. I did not belong to a club, I did not know anyone else who was into flying RC. But I wanted to get started.

I purchased everything I needed from Hobby Shack. A little 1/2-A high wing trainer called Mini Star, by Pilot; a Cirrus 4-channel radio, Cox engine, fuel, epoxy, rubber bands, battery, starting clip, etc. The cost added up to $213.36 with the 6% local and state tax. I priced everything from a 1974 Hobby Shack catalog. With inflation, that would equal $1115.69 today! Can you imagine. It was an expensive thing to get started in RC back then, and you had to be serious about it.

Well, I don't recall exactly but I think my first 30 to 50 flights were very short and all ended up with some sort of crash damage. Mostly to the front of the plane. With epoxy, balsa, and whatever else I repaired it and tried another flight. By the time I completed a full flight, IE ran the Cox engine tank empty, and landed smoothly, the plane looked completely different in the front! And it weighed significantly more. But, it was a glorious day! I had graduated!

A few years ago, I was thinking that it would be cool to find one of those model airplanes, and have it hanging up in my hangar, just for old time sake and to remember the challenge and struggle it was. I found a Cirrus radio easily enough. But the Mini Star ARF eluded me. I did see the balsa kit version come up for sale occasionally, the 1/2-A Baby Star. But I wanted the same ARF,

I was thinking about my very first radio, a Cirrus 4-channel from Hobby Shack. I purchased it in 1974, for a cost of $150, plus whatever the tax rate was back then. Looking at the US Inflation Calculator, that would be $784 dollars today. Plus the tax.

4-channels. No dual rate. No expo. No servo reversing. No LCD screen. No computer. No mixing. No programming. No software. No adjustable gimbal sticks.

Yes, it cost a lot more of your hard earned money to get into RC back in the day then it does now.

I got an engine made the same year I was born. I think that is pretty cool.

Just finished my Beaver today. I added a 3D printed radial engine and oil coolers. And an ESS-One Air sound system.

Wanna see some really awesome action? Look up Formula Offroad on Youtube.

Here is my latest RC car, a Kyosho FO-XX (Formula Offroad - 2X size) with a .25 glow engine, done up with some decals to look like the full scale racers.

RC Groups member, "Peter from GER" has made a 3D printable Pratt & Whitney R-1340 radial engine that can be built and then installed onto the E-Flite AT-6 foamie.

I am currently painting the parts and will assemble the dummy radial soon.

The STL files can be purchased for the mere sum of $10 USD and then you can print the parts yourself or have a commercial printer do them for you. Or, you can order a kit of parts from Peter himself.

This is my latest model I have built. It had some defects I had to correct but all is good now.

This plane was built and flown in 2006 and 2007. Last time out it had a hard landing and broke the nosegear bulkhead, broke the right main landing gear wood blocks, and broke the right wingtip. I hung it up in my workshop and there it has hung for 12 years.

I recently decided to get it going again. I repaired the nosegear bulkhead and cut away the crushed wingtip and replaced it and recovered it.

The engine was spotless inside and only needed some fresh oil.

I replaced the old FM radio with a newer 2.4 gHz version.

This is the FMS 1400mm "Sky Trainer 182". I suppose due to licensing issues they did not use the Cessna brand name.

Beautiful scale model.

Japanese version of the Me-163 Komet. This one has a cool paint scheme.

Today, I converted a Hewlett Packard 500W PSU to a 12V DC bench top power supply to use with RC battery chargers. I cut off 53 wires and 10 connectors. I grouped like wires together and then covered them with heat shrink tubing. I soldered 6 12V leads and 6 ground leads each in parallel. I soldered the power on signal wires together so that the power supply turns on when plugged into 120V AC. When I was finished I connected my Turnigy quad charger to the converted PSU and the charger lit up and then I charged a 2200 3S LiPo at 8.36 amps. Pretty cool.
