This used Challenger has all (or at least most) of the upgrade parts that I intend acquiring and fitting to the RTR Challenger that I bought during the Covid lock down, but against that , it has been run for the last 7 years.
Everyone looks for something different in their model tanks, and although this model has a lot mods on it that attracted me to it when I first saw it, I will feel happier after I have stripped it and rebuilt it the way I would like it.
Firstly, the tank came with a healthy supply of mud and grass from its off-road use, so I want to remove all of the debris and give it a good clean. Given the milage of the tank, I also want to check everything for wear and tear as although everything appears to be 'sound", I suspect some parts may need adjustment, lubricating or even replacement, so a lot of the tank will need to be taken apart to gain access, and so this could make an interesting Modern Build Log.
The spec of the tank includes a TK series board (of some description) that gives a very good Challenger engine sound along with good gun fire and associated sounds, but it is plugged into a standard 2.4 gig receiver that does not have an s.bus socket, so every function is plugged individually into the relevant receiver socket via its own "servo lead".
The HiTec transmitter that came with the tank has all of its driving functions on the right hand stick unit as normal, but ALL of the other functions work off of the left hadn't stick unit, and so by precisely moving this left hand stick up and down and sideways at very exact positions, it is possible ( I am reassured) to gain control of, the sound system on/off, the motor drive on/off, the turret turn left and right, the gun elevation up and down, the headlights on/off, the main gun shooting function, the machine gun sound and flash, and the second machine gun sound.
I can make all of the above work - but not necessarily in the right order (like a Morcombe and Wise sketch with a famous composer) .......and most definitely not when I want it.
Hopefully I can change the radio system that came with the tank and connect the TK board to a spare FlySky radio that I have, and connect it via an s.bus socket to give me a better control of all of the various ancillary functions mentioned above. I do hope this change can be made to work as I would like to be able to just operate any of these functions when I want them, and not have to fiddle about with the left hand stick unit in the hope that eventually I should stumble upon the function that I would like to use!
So the general servicing of the tank (including cleaning, adjustment and possible replacements) will be the backbone of this building log, making changes to suit my own preference (such as the way the radio system controls the tank) will also be covered as this may be of some interest as the project unfolds.
