Thanks to those that have made comment on this post. It`s always good to read them.
The first thing to do to fit the R/C kit is to remove the cab. Also,the reversing lever will be removed to make way for the reversing servo and the regulator has to be changed. Like it says in the instructions, the two regulators look identical so make sure you keep them apart. Once those parts are changed and the servos mounted, the receiver and batteries can be connected to make sure it works.

Next attach the reversing linkage

Then the regulator linkage

Now, following the instructions, set the forward/reverse linkage and then the regulator linkage. Mine seemed to adjust and set in the right places very easily but I won`t be able to confirm that until Sunday when I get to run it. The observant amongst you may have noticed that the pressure gauge position has changed. I found when I mounted the servos and the regulator link that the pipes to the gauge and also those to the as tank had to be moved to prevent fouling.
Once you are happy with the cab bits, mount the receiver in the tray between the frames under the cab floor and re-fit the cab with the battery box under the roof.

and there you have it

I hope I haven`t bored you all with this. I have really enjoyed building this fantastic kit and learned loads about steam locos. I`m looking forward to building a "Katie" next for my second grand-daughter.
I will try and get another video on Sunday running with R/C.
