The "Brazilian Piper Cub", it is sometimes called. It's very similar, but it's not an exact copy.

This is an ARF from World Models. It is distributed in the USA by Airborne Models, LLC.

My super duper wife bought it for me last Christmas. I started building it two weeks ago and finished today.

It is powered with a Thunder Tiger F54-S four stroke engine, a Zinger 11x5 prop, and has Spektrum radio gear and a mix of servos from Cirrus and EXI.

The graphics in the kit are representative of the type of aircraft registration used in Brazil, but they are not a copy of any actual aircraft. The models color scheme was based on an actual P-56 and so I ordered a set from Callie Graphics in the same registration scheme.

This plane really needs some Cub style wheels and I have a set of the lightweight Cub wheels from Dubro on order.

I am quite pleased with the quality of the World Models kit. It was a pleasure to put it together....Continue Reading

Here is a video of the first time my TVR1A engine has run on steam, being powered by my recently completed hand built boiler.

A little update to my custom FS-400.

I made a brass badge, to replace the stock ASP badge. But I was really skeptical about trying to put some writing in it myself, and I also thought it too small and thin for standard engraving.

Doing some research on the internet, I learned there is a new method (to me anyway) called "laser engraving". And a laser engraver can do letters incredibly small. So small that you would need a jeweler's loupe to read them.

Well I found a local business that does laser engraving, and I contacted them. I have a logo I designed for myself back in the 80's. I have even had the logo made into stickers for fun. So I inquired if my logo could be copied and then engraved onto my brass tag. Well, the answer was yes, and no. Can't do color, and the image I had needed to be turned into something called "vector line art". Buggha!

Well, I futzed around with my image using Photoshop and eventually got the color removed and something that I thought might be usable. But one was a jpeg, and one was a png. All I could figure out. Never could figure out what vector line art was. Anyway, I put it on a CD and then went to the laser engraver's shop with it and the brass tag. They were able to clean up the image, smooth it out, etc and make a vector line thing that they could use. Sweet!

So I had them engrave the tag. It looks great! Couldn't make the letters black, but they stand out well enough. The holes got elongated and my little screws were now too small. So I had some button heads that were a little bigger and able to work but I had to use the original tag as a spacer so there is a slight double line. But later I got some 0-80 brass hex heads and washers and now just the single plate is on the engine.

It's kind of neat to have a custom tag on my customized radial engine.

Darned honey bees discovered my hummingbird feeder and took it over! They completely drained it in a matter of a few hours. And the poor hummingbirds could not get a drink. Then the bees found the one in my back yard too!

Stupid bees!

I was recently looking on the internet for information on the available glow plugs for four cycle engines. I had no idea there were so many types/brands available. If you also look at 2-stroke plugs, man there are just so many brands and types to choose from now it is staggering!

Anyway, I took screenshots of the various 4-stroke plugs I came across in my search. Just thought I would share. ...Continue Reading

I have an ASP 5 cylinder radial engine. It normally just has straight pipes for the exhaust. It sounds great like that too. But when a ring or circle exhaust pipe is used, it gives the engine a more pleasing sound.

Commercially made units that I know of, are the Keleo Creations Inc "Magnum 400 Radial Exhaust" at $175 USD plus s/h. And also the Just Engines Inc "JEN Collecter Ring Silencer" at 125 GBP plus p/p.

Since I like to make things, and I also like to save money, I decided to try and make my own radial exhaust aka ring silencer.
