Fleet Control system conversion

[RobertC]

I had this set for a while and decided that the Reftec I converted to 2.4 ghz was such a good experience it was time to get a few more done..
This particular model was only 4 channel, I had an old JR plastic tx which I robbed all the switches ,knobs and pots from and decided to upgrade the Fleet to a 7 channel conversion....

The obligatory and fantastic encoder board from our friend PhilG was used and also Phils method of converting the separate trim pots on the system in parallel with the joystick controls worked very well ..

An orangeRx tx module used again for the RF output and connected up with the usual 8 cell nimh battery, once set up procedure carried out ,and just reversing the negative and positive feed on the throttle pot ,as this caused the alarm to trigger in full throttle position instead of low position, everything worked faultlessly.
I also converted ,but only as a 4 channel, a Kraft system , these were years ago way out of my budget and lucky enough to obtain a couple of sets....

Good Job, Robert!
Would you mind posting a pic and details of your 2.4 aerial mount on the Kraft please? It looks a very neat mount that you have used, where did you get it?

Hi Stuart

The mount used on the Kraft is a machined modified Futaba 'M' series mount I had several old sets which was used for spares 'cases ruined or dented , but great for parts..

I can gladly post closer pictures if you would like, I have a small machine shop here (not much) lathe Mill and Floor mounted drill press, of which with this enables me to machine up various parts, if you need any help I can gladly oblige....

I’ve posted some pictures of the modified Futaba aerial mount , starts off with a hole and slot(in my case) to the base , the hole is deep and wide enough to accept the sma connector which is mounted onto the top half of the now turned down aerial base , slightly counterbored accept the sma female socket ..
The coax is then fed through hole in base mount and screwed together , result is the last picture ..

Very neat and wold also work for those that have the screw on aerial base, such as OS, Sprengbrook, Simprop as well as Futaba...definite thumbs up from me.
It may well work better for those RF modules that have the plug connection to the module board, but may not work with brands that have a soldered aerial connection?
