WHICH MAST BASE FOR HYBRID FORMULA???

[robiceci]

I received today my HYBRID FORMULA, but I got the wrong mast base since it works on my other board, but not on this one.

It seems that in order to connect the mast to the board, a special type of base is required.

Can anybody help me? What's the name of that base? Who is producing them? Do you have a part number in order to search it without another mistake?

Unfortunately the INTERNET SHOP from which I bought the board is not able to help me.

Thank you.
