Reconstruction of other PIKO locos and cars to radio control and battery use


After the unfortunate death of our gifted electronics technician Hannes the concept of radio controlled locos with battery packs and sounds self made stagnated for some years. However, the reconstruction with a sound control based on ARDUINO for instance is one of his sophisticated legacies.

It can be seen and heard on YouTube. Pictures of the reconstruction I didn't get, unfortunately, because Hannes didn't succed to get some.

Some model colleagues returned to machines controlled digitally. In the period of powerful little battery packs especially with LiFePO4 and good radio controls I don't want to do like that. Perhaps it may be the own convenience to clean all the tracks before driving. But all the productive talks with Hannes and the contacts with other colleagues of the model car, boats and planes made me realize that there are plenty of other fish in the sea.

A little juxtaposition may explain my decision pro radio control and contra digital control. The used radio control mz-32 HoTT 32 Kanal von GRAUPNER allows me to memorize more than 900 models. Surely, never mind, I don't anybody to have 1000 locos in his garden, but it shows the big redundancy inhereting in this system.

32 channels controlled by switches (digital controls have only 28 channels switched by a keyboard with 10 keys) with 3 switching modes for every channel allows a lot of switchable function to be carried out you couldn't remember on or limited by available power supply. However, the clou iss the sum signal whhere 64 digital driven switches can be operated which can even be combined in logical ways. The Soundmodul - which controls the model by a powerful enggine controler (30 A) - of BEIER Electronic with operational and 30 additional sounds hard to remember.

If I compare the cost of the different systems (june 2021) the most advantageous decision was easy to get. Radio control almost 1,000 Euros; on digital way the main digital device plus power supply - without power the system doesn't work - plus a handheld device and a receiver of the german company Massoth ca. 1,300 Euros. Then the costs per vehicle -- on my way the battery pack (ca. 6,000 mAh) plus the sound and engine controler plus some little things like cables, fuses, switch etc. ca. 350 Euros whereas digitally controlled by parts of the german company Massoth (surely the would be somewhat better parts to use) with power storage would cost nearly 300 Euros.

Let's loo into a tender of a german loco BR 50...

Now a short explanation of the main parts

1 - portable battery pack (LiFePO4, 6,000 mAh); 2 - main switch; 3 - receiver GR-32 HoTT2.4 GHz Dual 16 channel; 4 - main fuse 5 A; 5 - sound controler SFR-1; 6 - power controler; 7 - loud speaker FRS 7 von VISATON

1 - battery pack stationary (NiMh 4,200 mAh); 2 - main switch; 3 - charging plug; 4 - loud speaker FRS 7 plus switch board; 5 - sound controler SFR-1; 6 - main fuse 5 A; 7 - receiver GR-32 HoTT2.4 GHz Dual 16 channel

However, the sensitive models are exposed to all sorts of dangers on their travels to various exhibitions - the original boxes would have abandoned finally. For this cause, another solution had to be found that was easy to use on the one hand-side and stable on the other. The selection were aluminum profiles and a lot of screws from an ordinary hardware store.

The electro locomotive class 254 in its transport frame, which due to the foldable LGB rerailing aid proves to be a grateful option for driving directly onto the track and which is therefore not entirely insignificant about the chassis design of this locomotive.

Here the german class 50 in its transport frame (the rerailing aid is still missing in this photo). Behind this the frame for the german class 118.
Especially for the german class 50 the frame reveals to be the golden solution, because it means that the sensitive add-on parts or the multifunctional connector between the locomotive and tender are not exposed to unnecessary strain.


Bei all discussions about pro and con - I'm the opinion that this is conclusive and simple realizable solution resulting from all my experiences summed up during the last 10 years.

In this sense a lot of fun with our common sense!
