RC equipment modification...

[tiger1]

After a few days of holiday, something happened in my RC garage....

Well, not very intelligent but it was fun to me. I know some may think this is a crime....

It all started because, since a few months ago, I thought my 75mhz AM Futaba Attack was old, well, after all, I got it for less than USD$10 back in 1992 when I was going to school in Chicago.

One thing I did not like about the attack, even though very economical and robust, the trim shifts a lot, I have to adjust the trims everytime I run my cars, even though I do not run my cars too often. Well, this was a design problem, there ws one rheostat for each channel and the trim was simply a physical shift of the whole rheostat, which was a bit pre-historical.

Then I found this Expert 7ch transmitter NIB for sale on the bay a few months ago and got it for ~USD18, shipping was expensive though, cost me close to USD$50 in total....

It is smart looking, professional look alike, after all, with many switches and buttons

I told my colleague at work, the whole reason I bought it was because it looks smart, as though it would have changed my IQ by a % point or so

Then I went on to do some difficult surgeries.

My assumption were that:

(1) the rheostats for the 4 main channels are the same in values between my Futaba attack and the Expert transmitter, if I were wrong then I would have to use the Futaba rheostats (and I was correct!!!),

(2) with some time and elbow grease and luck, soldering and un-soldering, this should be an interesting, even though not highly intelligent, project

(3) I always wanted a metal case transmitter anyway,

(4) a transmitter with numerous buttons may raise my IQ by a percentage point

Ok, at the end, the project was successful.

However, only one of the switches on the top panel was used for servo reverse. the other switches were there to show of my intelligent capacity (or dis-capacity)

The main advantage was that now there are 2 rheostats for both channel 1 and 2, the additional trim rheostats make fine adjustments so much more reliable.

This is still essentially a futaba attack 2ch 75 mhz AM transmitter with 20+ years old technology.

This project reduced my net worth a bit but did not change my IQ in anyway at all, which was disappointing but not surprising...

did not increase or decrease my IQ in anyway at all, which was disappointing but not surprising...

Hmm... If your IQ was reduced...... would you really be able to notice it ?...... Just a thought

He wouldn't the rest of us might
Coo ljob on radio all the same
