Pro-Line Competition Series Transmitters
Posted: 31 Aug 2020, 15:49
Managed to acquire a couple of Pro-Line Competition Series transmitter, one of which I have converted to 2.4 using Phil's Encoder and FrSky XHT module.
Thought it would be interesting to compare the differences between the Competition Six and the later Competition Series transmitter that I have.
The Competition Six is I believe an early model and there is evidence that it is a pre 73 model.
The Tx had a long (12.5 inch) top mounted aerial, which I felt to be too vulnerable to catching on things when in use and have now replaced with the standard FrSky 2.4 antenna.
The locking switch and meter are identical to those use on early 70s Kraft sets and the control layout has the two propo channels on the lower front face. There is a trainer button on the top left of the case and this is used as a minute minder on the new installation.
The internals are different with the encoder and RF all mounted on a single PCB, whereas the later tx has a separate RF section mounted next to the retractable aerial on the top face.
The Comp 6 is powered by two separate GE Nicad packs fitted to the lower face, whereas the Competition Series has a battery box for 6 pen cells fitted to lower face in a bespoke moulded box with charging socket fitted to the rear face of the transmitter. The control layout of the comp series has a propo & switched channel as well as a roll button with a trimmer pot fitted to the top left, the trainer button is on the right hand top near where the the RF module is located.
The thickness of the Comp Series is less and the stick bezels are smaller than the Comp 6. The Comp Series is fitted with a Pro-Line meter and a non-locking slide switch.
Due to lack of space within the Tx, I stripped the components from the Comp 6 PCB so I could mount the encoder and RF module hidden out of view.
Have attached pics of both transmitters as well as teh 12 V Field charger that cam with boxed Comp Series.
I did find this:

but if anyone can shed some more light on the history of Pro-Line, then please feel free to do so
