I have a few items that I removed from mine. I changed mine to an AS1 and scratch built the different parts needed. I have the tools for the sides of the hull, I was going to suggest the two German sites, but I found that there is the option of using one of the English sites (Welsh dragn offered to try and import bits for me) and they wil import them as well (I spent over £400 in 2008 getiing parts over) I bought a brand new gearbox, try
service@hobbyco.net I pretty sure they were the ones who supplied mine. I reckon yours will be running before mine. I havent read any bad reports of the track upgrade, let me know if tou buy some, mine are pretty grotty. I think I'll be buying some oneday. I'll PM you my work email address.
