and a bag full of resistors, caps , breadboards, strip boards and assorted electronic crap from

we'll see how this all works out, or not
so far about 40 bucks in
should be cool

Sweet . My first plane was from heath kit . It never flew except when I hopped it up a curb it took off into a tree. Can't wait to see cj's trip out when your banging the sticks and doing what they never could with a 60 year old radio .

I just might know where I could lay my hands on an old Kraft. Soopacool!

Nice! :tu:

I bought and built my first radio back in 1969, which was a Heathkit GD-19 just like yours. Back then 72 mhz was brand new, so I went with the well proven 27 mhz. A few years later the CB craze got popular and pretty much made flying on 27 mhz too risky. In hindsight, I should have gone with the 72 mhz.

If an old GD-19 shows up for sale sometime, I'd probably do what you're doing just for the novelty of flying an old radio again.

You know you could buy an aftermarket ar9x board, using ersky or opentx, install it in a radio sans screen, and still be able to do advanced programming on your PC, or use it as is.

Many years ago I had a Kraft single stick transmitter. Bought it as part of a package deal. I was walking through the Altoona Pa mall and the local club had a table set up. A guy sold me an old Balsa USA Northstar with the Kraft radio included for $50. I could not use the radio (old 24 frequency). I put everything back in the original box the guy gave me and put it in the basement. About 4 years later took it and threw it in the trash. As I threw it in the trash I laughed at the fact that it had the original price on the box of $584.

Later that night thinking that throwing it out may not have been smart, I checked ebay and decided to fetch it out of the garbage can and sell it. Ended up getting over $200 for it. Plus the guy paid for me to ship it to Japan. He said he rebuilds them, changes the frequency and resells them to the vintage pattern guys over there. It looked just like this one:

Airtronics Vanguard! I flew my Scat Cat at the Green Bay WI ProBro last summer, which is still controlled by one.

I looked into that, the board may be too big for the enclosure and I would have to change out the pots and mount digital trim buttons and the associated boards. If the Arduino rout is a total pos or doesn't work maybe I'll try that or something else.

My first radio was an MRC with lineal servos like this one:

Those servos were cool and provided an even throw throughout the travel. Always wondered why all servos were not designed this way vs a stupid wheel. Guess Expo eventually solved the problem of wheel design.

did that buzzer come with the kit,or did you source it separately?

I wish it was a kit, it's all sourced separately

I finally got the POS to run through a combination of luck and fear of failure. I have never worked with code and it was a steep learning curve for me. Loading and tweaking the code took some time.

Now onto cleaning up the wiring and programming- witch is done through a serial monitor with dos like commands making this thing kind of impractical for modern profile flying. A fun project for the PC programming, code writing type but a bitch for me.

Lot of time and effort just so I can go to the field and be "different" :bag: :doh:
