Oh, IMHO it is not a bad thing to observe the weight of a battery, because in my Jagdtiger the difference between lead acid and LiFe was more than 18 kgs! The lower the weight, the longer the run time; especially in rough grounds! Please remember the headline of this thread...... :wink: Some towing ...

A BMS is a simple and comfortable thing, which e.g. seems to 'transform' a LiFePO4 battery containing four cells to a simple lead acid battery containig six cells. Then you can use a simple lead acid charger with 12 volts fitting a car battery. But most of BMS limit the peak charging voltage beneath...

Single cells are better AND cheaper, When you can spare a BMS! But single cells without BMS MUST be balanced when loading, and you need a reliable system to recognize the end of discharge of every cell (to avoid deep discharge). Complete batteries use a BMS which adds some cost and prevents the cell...

This is a possible display of my transmitter. In the right side you can see the voltages of the single LiFe cells. I programmed a spoken warning for each cell deceeding a minimum voltage when not using a BMS. Another very useful screen shows the consumed capacity in amp-hours, the total voltage and ...

I'm using LiFePO4 batteries in four of my five models, with and without battery management systems. If you don't use a BMS, another kind of monitoring each single cell is mandatory for charging and discharging. Lead acid batteries should be discharged only to 50 % DoD (depth of discharge) for a good...

Nice pieces! Ammunition and its containers are interesting parts. Some years ago I ordered the ammunition for the KwK 43 L/71 (King Tiger) with its 4 kinds of shells. It was a rather expensive thing to create the CNC files and build the cartridges from brass and the shells from aluminium: https://ab...

The risk of having a runaway model is present even when using modern GHz RC equipment. In Hausen I saw until now 2 near-accidents: 1. The first model started uncontrolled out of its stop position at a public street with full speed, jumped over the kerb, missed some visitors and dashed against a tree...

I think the behaviour of a receiver missing its transmitter signal is depending on the manufacturer of the RC equipment, but most of the modern GHz receivers have a free programmable fail safe for each channel, and a modern ESC stops the motors immediately when missing a convenient input signal. Mod...

Hello Robert,

PM sent.

Hi Oli, if there were tested 3 different transmitter / receiver combos with the same result, then I would seek the reason in the ESC module. Do you use a cross mixer option (one stick direction for driving both motors, another stick direction for steering) or do you use direct steering like driving ...

Gun fire and smoke are very difficult things to show at a model. IMHO a gun recoil is some easier to realize and some more effective than gun smoke. Just have a look at 'my' M48 firing in the dusk. As its driver I could take a look from the outside. With a sharp eye you can even see the tracer of th...

Hi Lerh, thanks for reply. I am using three models with Olaf's steel tracks (one with aluminium roadwheels, two with zamak roadwheels), and I also couldn't find any excessive wearout. Only the Jagdpanther's drive train is worn out due to misfitting steel tracks. But some little wear is normal when u...

Hi guys, Reinhold's annual tank meeting in Hausen am Bach (Germany) is fixed for next year. Arrival and first action will start at July 17, 2020. The main battle starts at July 18, 2020. Further details will be published when fixed. All kinds of military models in 1/6 scale and bigger are welcome. P...

Here some further pics of the monster. I shot them in Stammheim:







4 x 500 watts powerplant:

It is true that the KGS 73/800/152 was used in the field and not only on prototypes, because Olaf's single-link (the original) was found near the Eifel, and it was a worn one (today it is part of the wheatcroft collection). Therefore I think that at least some king tigers were equipped with these tr...
