1/16 chieftain MK3 not a HAYA!
 

Hey folks, been a while since there's been any progress on the chieftain. An abortive commission job later (which I still need to put right) I'm finally making some progress on her.

First job was fitting the gear boxes, got a good deal on some waltersons steel ones so they went in. However I will be replacing with a PDSGB once they come back in stock.

Next up Andy gave me a great deal on the metal chieftain running gear so that had to.be done. There was a bit of slicing and dicing to get the idler adjusters to fit and I needed to fabricate some spacers to get the correct sprocket alignment.

I've also had to add strengthened springs to the rear and front bogies as the original ones were too soft and was collapsing.

For the video she's running a Clark tk60 sbus. She's on es and is probably still too slow so looking at a PDSGB at some point

Very nice work Tom. Are you printing this stuff yourself or was this a semi kit from a small time mfr?
So what did you use for your tracks and sprockets?

Hey, it was printed by chap from my club, I bought it as a shell, it needed the mechanical side and assembly and detail doing.

The running gear is the metal haya stuff. I had planned on using reversed bulldog tracks but they were too wide. The Haya stuff fitted nicely and is more accurate so win win.

Some little bits of progress on the chieftain. The waltersons gearboxes have come out and been replaced with a pdsgb. I've got them in other tanks so when a new one came up for a decent price on ebay it was jumped on. At vast expense I ordered 6 new track links so i could reinstate the adjustable idlers adjusted so they looked right (were too far back before).

I'm really pleased with how it's running, since I got the tension right and had the sprockets running true on the pdsgb shafts I've had no track throws, it'll neutral turn on rough grass without issue. I'm running a tk40 (as I had a couple spare) currently, unfortunately I've since found that to run the 550 motor of the pdsgb you need a tk60/80. 3s tripped the thermal cut out almost straight away. 2s has generally been ok but does trip after a while. I'll be swapping the tk60 in my m51 with the tk40 here and that should sort it. Speed with the fast gearbox on 2s is probably scale but I like to have some in my back pocket so will be going to 3s once I get my tk60 back.

Sadly my barrel was butchered by the guy I commissioned. I jumped for joy when I saw haya offering it separately, until I saw it was £80!!!!!!

Mk modellbau stepped into the breach. Got dimensions off a friends 1/35, scaled it and Martin did the rest. It's going to have the thermal sleeve added when I get my hands on it.

Next stage will be tidying up the work done when I sent it for commission. I also think it's going to be upgraded to at least mk5 standard, probably one of the later ones. Watch this space.
