when in doubt..

…check biplaneforum.com There are a surprising amount of active builds going on, and luckily the Acroduster is alive and well. Just an example: here’s a pic of an ”original” compared to mine. Isn’t that fun! I will have to ask the original posters if I can use their pics here, so right now I’ll leave … Read more

Every engine needs a firewall.

Slow day today, ran out of silver again. Never mind, Ralph from sonderlote.de is sending another load! Anyway, stumbled across a bit of aluminum that just looked like it wanted to be a firewall. I made it the high tech way, from dxf to cnc. Of course I keep saying to myself that in order … Read more

Tail wheel support.

Wanted to keep this reasonably light, not perfect scale, but looks close enough when done. I can always change it! Mounting is with 2 M4 screws. The seat is built from 6 alu strips going front to back and 7 crosswise. Sort of like in this test. I need to think about this a bit, … Read more

How to build your own plane

To view everything it wants … Read more

One legged plane

After brazing

Closeups of my handywork. After sandblasting I ‘ll reheat the joints to make them flow a bit more and fill any voids leftover. This will be for cosmetical reasons only.

Wing & u/c attachment hardware

The plans call for square tubing for mounting the wings, but you guessed it, not available in the size I want, not even close. Here I have to deviate from the plans and make something that will look the same, but is something I can make. At stations 31 and 51 I added the normal … Read more

Rudder finished as well.

As you can see, the new shipment of tubes has arrived. Visible progress is made again today. Overall I’m happy with the result, there are always little things that do not quite turn out as intended, but since this is all about learn as you build, it’s not a disaster. (So far I have not … Read more

Adding some direction

Just a relative quick job tonight: making the fin. The only noteworthy item would be that after installing the ribs, I still had to drill a hole for the bracing rods. I decided to simply cut a slit with the Dremel and enlarge it to fit the tube. Seems to work well, and since it … Read more
