Re: 31st Jan 2020 - new kit announcement

Re: Engine L60 for Chieftain

Ivano, these should help. I regret to say that L60 failed me once too often and when the last one blew its liners and started burning coolant, emitting a large and very white plume of smoke, I levered off the L60 maker's plate on the top cover. I kept it for several years but in a Marie Kondo moment...

Re: New Member

Good luck Brian and welcome. The Knowledge Base is a good place to start. Talking of the 25 pdr bowing out, in 1992 I saw the last round being fired in British Army service by the Honorable Artillery Company on Salisbury Plain. I had the privilege of flying the observer who gave the order to fire. H...

Re: Chieftain build by Phil Woollard.

The BATUS tanks were painted centrally by the activation party crews at the beginning of each season using spray guns for speed and efficiency. There were few exceptions. In BAOR it was the opposite, routine painting was done on the tank park by crews, usually using brushes, which would result in sh...

Re: Maximizing Run Time?

AJ, "we're done here" I thought but maybe not. Sounds as though you've worked through to a conclusion you're happy with. 60lbs of battery weight would be excessive. You also have to remember that the torsion bar suspension would be challenged by that much weight. I would aim for about 10-15 lbs max....

Re: Tom's FAMO Build

Tom I'm enjoying your interesting and very professional build. It's inspiring. It's also good to see someone following advice and using dry moly lubricant rather than grease, which is not recommended. You've got a great machine shop. I'm a great fan of Joe Pieczynski's YouTube channel, I learn a lot...

Re: Maximizing Run Time?

AJ, the other options may be a fun challenge but for safety and reliable performance, a single 24v LiFePO4 battery with integrated BMS is undoubtedly the soundest option (and the smallest/lightest).

Re: Chieftain build by Phil Woollard.

Phil, well done, looking good and it’s great that you chose to sort out the thickness of the driver’s hatch. I’m going to sound like a broken record though and just say that a rust finish on the tracks looks anything but authentic for a Chieftain in service. Now I’ll shut up because I recognise that...

Re: Maximizing Run Time?

Not sure what point Gerhard is trying to make here. The “complete battery” is made up from single cells. Both types of array should be protected by a BMS in any event. In the case of my Centurion incident, had I not had a complete battery with integrated BMS, the battery would have been discharged t...

Re: Maximizing Run Time?

Telemetry is not only easy to fit but very, very useful. Most modern RC systems now come with integrated telemetry. Soektrum for example offer a basic installation, to which you would simply add a voltage sensor, which is easy to install into your power leads. Ive also fitted a current sensor but so...

Re: Maximizing Run Time?

All I can add is that I've run my Centurion over three days at TankFest without recharging and the voltage never dropped below 23.5. That is using a single 24V 22AH LiFePO4 battery. The problem with lead acid is that the discharge profile is such that the effective voltage drops below a usable level...

Re: Chieftain exhaust question

Dan

- purely cosmetic

- main engine exhaust OD is 192mm, aux gen is 72mm. I've extrapolated from the drawing so may be +/- a few mm.

Re: Chieftain build by Phil Woollard.

"At present the turret touches the rear deck" That's because the kit hull is raised in the area of the engine covers. On the real Chieftain, it's only the transmission decks which were raised, in order to accommodate an increased capacity exhaust system. If anyone chooses to enhance the accuracy of...
