I have got a secondhand kit the Laser 3D Mini It came with no building instructions.Would anyone have them that I could buy or copy? Thanks

Do you need plans and instructions or just instructions?

I have the plans but no instructions.I have it built now but do not know how they are installing the servos or the radio gear.or what the C G is. Anything would be a help Thanks

The instructions are pretty poor. It is written in 4 different languages and the translation is not the best. The cg is 65mm from the leading edge for fun fly or 75mm for expert. Ailerons throws are 15-20mm fun or 30mm expert. Rudder is 25-30 fun or 50mm expert. Elevator is 10-15 fun or 20 expert. These are the numbers taken from the manual. As far as radio installation, just install the servos in the supplied mounts that are built into the plane. You will have to determine reciever and speed controller so the model balances were you want it to. They are installed above the wing in the fuselage.
Hope this info helps. This is a very easy flyer, and alot of fun. Good luck
