I will do the Chieftain Mk.5 in its own thread Stormbringer ;)

Good morning MonsieurTox :D I see we have much in common in the hobby world, I also had a GWS F4U Corsair some time back and it was a excellent flying plane and was very scale looking with respect to take off landing as configured. I built it very light and that made a big difference. I still have an operational GWS Zero and Mustang on the flight line.

Good morning Modler :)

Yeah we have even more because when I was a kid I always wanted to convert my 1/35 Kits to RC ! Unfortunatly, unlike you I never been able to do it, batteries were too big and all the electronic as well (or super expensive, no Aliexpress back then :S).

Yeah the GWS Corsair was great ! And beautiful, I guess the Zero and Mustang should be the same !
Unfortunatly now I moved I dont have place to fly planes. However I bought 2 Eachine parkflyers, the Corsair (how surprising :{ ) and the Spitfire. So I still can fly ;)

Yes, the model you mention has Fruialmodel metal tracks. It is a 1/35 Tamiya (1975) Chieftain Mk.5 motorized remote control version. It is also a scale runner with a modified Taigen Transmitter. I bought the Chieftain from a chap in Britain a few years ago via ebay. It was new in an unopened box. I will do a thread on that one soon.
The friulmodel metal tracks are great stuff ! That's a nice looking Chieftain you have there (I had this kit but like all the Tamiya kits of this era, I ended using them to kitbash my star wars filmining miniature replicas ;D ).

I can also see some nice Bulldozers !

You mentionned you were modifying your transmitters, I understand the additionnal switch you put on them are for low (correct me if I'm wrong), but sometimes I see 2 switches ?

Yes I have a few bulldozers as well They are tracked vehicles so they are worthy of my interest :D

Here are a couple of Dozer videos

I have been playing around with one of the a four Dozers a good while and have a few more that I have built recently.

Here is a video of a Dozer I did today with my latest Transmitter mod ;D

I see three identified (licenses, presumably) as Cat, one that sure looks like a D series Cat, but is not so identified, and one (second from the left) that I cannot identify. Can they push snow? ;)

Greetings Herr Doctor. The second one from the left is not modelled after any real machine but is a "Toys R Us Fast Lane model". The third model from the left is a Chinese Huina model. These Dozers and Four Excavators are the reason I only have one 1/16 Tank. I simply don't have room for larger models these days. My wife and I have downsized our living space and garages as part of our retirement strategy.
I do have a nice tree stand in the large yard to run my Tanks and construction machines.

Greetings Monsieur Tox,
Yes I do a lot of transmitter mods to get things to work the way I want them ;) On a Taigen Tiger I did a speed set switch mod that uses two slide SPDT switches. The first switch selects F\R, the second selects speed set on\off. I eliminated the one of the switches using a single SPDT center off toggle switch on later variants.

To modify the response of throttle- steering on the TX, I cut two traces on the circuit board R1, R3 where there was room to add new resistor values and added two connectors that come to the outside of the TX so that hand built PNP resistors harness can be switched out to evaluate changes to throttle and steering at different speeds.

Here are two HL transmitters. V1 and V2. I am testing with various PNP resistors to find the optimal resistance needed.  The two resistors shown sticking out on connectors are for steering and throttle. These resistors set a analog "expo" of those functions mentioned.

Here is one of my latest HL TX mods. This one has a SPDT with off center position. selects F\R speed set. The Side mount POT controls the amount of speed from Fast to slow.
