As the weather cooled, the humidity hit 100%, & the lion sweated, full left glitches mounted. The lion kingdom believes it was water intrusion in the stick controller. Walking speed made the glitches go away. A steering linkage also came loose, as the PLA eventually stretched until it no longer gripped. This ended the trip after 16.9 miles.

This is my Dad and me in the early '90s. My Dad's approach to building aircraft, was to make many improvements to the traditional aircraft as possible and to set standards as high as you believed you could attain. Most of his aircraft surpassed, even his own standards.

My education about building aircraft came from hundreds of hours in discussion with him about every aspect of aircraft design and development.

This was his career:

Hmmmm , In deed .....

Ok the problem with the P1B-1 ...

The folding prop was the problem ..

A) The prop weighs too much
B) RPM and torque roll are effected by the heavy prop
C) Props hangs or folds , changes CG
D) The folding prop is a nasty cheap affair ...

So after a while I realized the folding prop was the problem and the model was hung up as an ornament .

The other day one of my FF models with a timed electrical system fell onto the floor .... Ding Ding !
And a idea flashed into my brain ...
For over a year I have been wondering what to do with the P1B-1 , mostly geared around some form of RC .
But what if I could ? Fit one of these timed electrical power systems ...

The battery fits in the tube , the timer / switch fits in the tube ..
I 3D printed a motor mount for the pusher set up .
The P1B-1 glides amazing without that brick of a factory prop .
The power system has been tested in doors , but not out doors ( very windy ) + the mod is barely 24 hours old .
It looks promising !

I was lucky , the 3D printed mount came out perfect 1st time out .
The motor is a 7mm DIA and the system uses a Lipo battery that is USB charged VIA the timer .
There is not enough power to pull vertical , but horizontal should be fine ..
Hopefully be some fun , especially as the rubber powered factory set up was a PITA .

What I need now !
Is to 3D print a nose cone that allows me to push the start button ..
My 1st attempt at such was a full fail

Down to push rods and control horns....and I'm going to add the red and blue stripes to the stab to match the wing.....but I like it !!!!!

Edit note....I added the stripes to the stab.......

Had a fun day last wednesday 11/24/21, with my friends at our Club Borinquen RC in Toa Baja, Puerto Rico. One of my friends prepared the attached video of the day flights and sent it to me on my birthday last 12/2/21.

Even thou I am 69 years old (you are only "69" once), I love Rock specially Gun's & Roses, Rafa prepared the video with 2nd section with one of their signature tones. I really appreciate him for many things and this is just one more.

I love my A-1 Skyraider "Chona La Puerca Asesina", for its looks and flight characteristics. Hope to continue having birthdays sharing them with my wife, kids, friends and models.

Hope you enjoy Rafa's video of "Chona"

Das Ugly Glider - Part 8

Alternate color scheme......Still have to cover the stab..Fuse and fin are white, black landing skids. Pic tomorrow...'supposed to rain all weekend.....

Of note, I'd forgotten what a PITA scalloped control surfaces were to cover...LOL

Well today's clustermess is courtesy of the US Postal Service (Wait, did I say "service" ??) Seems my covering material left Gurnee IL 8 days ago, traveled to Charlotte NC, and is now on it's way to Dallas TX.....Did I mention I'm in Memphis TN ?

I don't have any words for this situation (well, I do, but they would get me banned from RCG) So I changed the color scheme for the glider..white with red and blue shoulder stripes, black trim....Pictures soon

Klemm L-25: The German aircraft manufacturer introduced the Klemm L-25 in 1928. The airplane had a long sailplane like wing and used all wood construction similar to 1920-30s sailplanes. The L-25 had quite a few variants and powerplans. Throughout the years Klemms have been powered with ABC Scorpion and Bristol Cherub 2 cylinders, Continental and Lycoming 4 cylinders, radials like the Pobjoy Niagara, Salmson AD-9, Siemens, Diamlers and BMWs as well as inlines like the Walter Mikron, Hirth and Argus.

In the US the company Aeromarine license built Klemm 25s for the US market. They were powered with Salmson AD-9s which were imported by Aeromarine and later had LeBlondís. In the UK a slightly modified version was produced as the B.A. Swallow. In total at least 600 were built but with many built by homebuilders, itís hard to say exactly how many have flown in total. Today there are still a lot flying in Europe and a handful in the US....Continue Reading

Hayden-Clark Timebuilder: I canít believe I havenít done a writeup on this airplane considering I own it, but I realized somehow Iíve passed over it.

The Hayden-Clark was built in 1931 in Visalia California. It was put together by a shop teacher and one of his students at the Visalia airport. I believe they had the wreckage of a Jenny as the entire instrument panel was out of a Jenny and quite a few fittings and other bits were Jenny as well. Somehow they managed to get their hands on a brand new Salmson AD9 radial to power it. They completed the airplane and it was test flown by Sol Sweet who was a well known pilot in the area and was the founder of the Visalia airport.

Sol reported that the airplane had lovely flying characteristics and that it would recover from a spin hands free. Amazingly, the builders managed to get the Hayden certified through the CAA group 2 approvals. They got started on building two more of them, this time with two seats, but they were never completed. Which makes the Hayden-Clark a very rare breed of one-off certified airplanes.

With the depression in full swing, there was no money to back the building of more airplanes so the only airworthy airplane was sold off. Pansy Bowen, a rare woman pilot in the 1930s purchased the airplane. She was cited in a registry at the Clover field in Santa Monica California stating she was on the way to Cleveland with the airplane. Whether she made it to Cleveland or not, I donít know. But eventually the...Continue Reading

I liked the Freewing F-5 jet, but it was to small for my aging eyes so I decided to convert it to have delta wings.

I programmed the AR636 stock receiver that was installed in the 2018 June Nite version and noticed maximum bank angle of 90 degrees left and 60 degrees right. I donít want to trust the 636 chip and will go to the AR637T chip for now as it has so many valuable features. The 85 degree down flap angle is great for vertical 4455 degree dives to to the runway and with appropriate up elevator and timing a spot landing can be made with 5 training attempts for the newby club member.

Using Satellite finder as battery operated field strength meter for RC.

I wanted a device that I could use to compare transmitters to one another as a reference without actually connecting them directly to the transmitter or antenna. I first tried using an old field strength meter in the past but the fact that there was no amplification inside the meter. The power SWR field strength meter WAS DESIGNED with a power scale for 10 or 100 WATTS, the meter had very little movement and some transmitters didn't deflect the meter at all. I found a solution. I needed something that would handle much lower signal strengths and cost next to nothing.
