Pro-Lines for the 21st Century

[stuart mackay]

One of Lemon's best UK customers (Pattern Flyer and serial Tx converter, Andy Hopkins from Somerset) has just produced these two beauties that I thought I should share with fellow Forumites!

Both converted using Mike's GTS encoder (as he tried to use the PPM from the Pro-Line but found the channel mapping was incorrect for the Lemon DIY) coupled to LemonRx 2.4 RF module https://www.ebay.co.uk/itm/133704108565
Enjoy!

I dont normally do conversions for others but Ray asked very nicely, I had to find him a Pro-Line Comp 6 which IIRC came from Duie.
This was nearly 5 years ago, very little room inside, a 2S 800 just fits:

Very nice Stuart and Phil! I have a couple of dual sticks and a single stick ProLine Competition Six - each with the wonderful all metal gimbals - that are in my project queue, so very interested to see how those turned out.

Stuart - looks like the original encoder boards were kept in the conversions - is that correct? Any particular reason why?

Phil - it looks like there are wheel trims on the vertical channels (elevator & throttle) but regular tabbed trims on the horizontal (rudder & elevator) ones, or is it just that the centers of the horizontals are painted or something? Does/did that unit have the cross trims?

Hi Bill
re the trims, the set went to Ray a long time ago, I recall they were all 270° trims, and yes the white dot disappears under the slot! most peculiar!

When I finally got one recently, I found it interesting that the Futaba Module 7 of the late 1970's, AFAIK the first Futabas with a plug-in frequency module, seemed to emulate a lot of the features of the ProLine Competitions (I think Futaba was trying to break in with the top pattern and other contest fliers at the time) including the 270° wheel trims in a cross-trim configuration.

Often try and keep the original PCB if space allows, we dont know what folks might want to do to them in another 50 years!?!

A couple of mine: 2.4 GTS/Lemon converted Comp 6 Mk1 and a Mk2 in original 72MHz, enables you to see the subtle differences in case design, sticks, batteries, circuitry, meter etc between the two iterations of Pro-Line
