Hello MPJ What do jou have a nice project! All the details are very nice I am building an excavator and I use the Lego Technic 8043 as a base I have a few questions about the volvo excavator, and would it be great, if you would help me on that! Do you have a picture inside of the boom. So I can see the power functions M motors to operate the cilinders? Are the M motors in the boom strong enough for the cylinders, or have you delayed them? a Do you use the same batterij box as the 8043 Lego set? I use a XL motor to lift the boom, But i have one problem, when i use the battery box with rechargeable batteries (7,2 volt) then are the M motors weak! And I would like a strong beam When I connect a 9volt 1500mah adapter on the Lego power functions I/R receiver, it does not work to send a signal with the remote ontrols to the motors? Could you help me?
