Hi Liam,
I am happy to read from just another one, who is infected by th TTTT-virus:-)
If I undestand right, you are looking for the "Lemo-Solar"-motor thats is right for the driveline???
Just take a look at the webpage of LEMO-Solar (
www.lemo-solar.de) . There you will find the "Truck Trial - Antrieb für M 1:87 (Bausatz)" and it costs 29,90Euro.
If this one is the right one, the order number is "MC 195". I think your number was wrong???
Small batterys, I prefer LIPO-cell. One of them is good for 1h TTTT-fun and they are very small (in this case 3.6V are enough for the car) . You can get them at
www.1zu87modellbau.de. there are also spare-batteries to use in a bit-racer availible.
best regards
Thorsten
