Hello all and thank you ...first sorry not been on here for a while very busy .... Ok the machine mini machine I have one thing not happy about ,,,,but other than that it runs on 2.1/3 v it's smooth ant the motor is half the size as my normal motor the piston and housing is mallee even the vice is smaller not the hole for the back steam same size ... I have shrunk every thing apart from the frame because of dimension ....the motor has loads of power but does back up so it is softer and specifically good for b+g I have been testing motors all last year this motor is good same price as the norm motor though boooo....but smaller throw2/2.5mm make it even faster making nice smooth grads I have used for a while and yes it's made grey wash easier for me and I hate grey work .......1 more thing I had a 17 curved mag on it for 3 hour sesh and smooth .....I try get some pics ip for you many thanks again
