Out of interest rolland, what other trucks do you have? The CEN and the XTM but what are your others and which is your favourite?
I have to say that the GS is my first choice at the moment, however you cannot ignore the vast quantities of spares for the HoBao (Ofna in the U.S.) Hyper 7. They are everywhere! There is a private sale I have seen for one buggy in A1 with an 8port, plus enough spares to make a second buggy, all for £300. I have to say I am tempted. A running buggy and the basis for a truggy conversion all for £100 less than a new truck.
EDIT....Santa has spoken. GS SUT pro will be making its way to me tomorrow! Can't have it til the 25th though!! Booo.
