to open it up once i had noticed i had an 06a04, immediately without addind anything i just started playing it the steering back and forth , sounds way different way quieter hard to explain, also i then tore off, the craddle and flipped the pcb, now the wires are wired to the pcb exactly the same as the 7/7 mod and so far everything else looks the same iside, in about twenty minutes when i get some batteries in here i will let you know about the new steering, i almost want to say i think by the sounds of things there will be a full 7 steps and also way less jitter!!!!!!!!!!!same green steering motor just noticed that
