One of my race friends had one in his WGT and got another for his 1/12. It was a very tight fit on the chassis due to its size. The thing is bigger than the RS and RX pack combined, weighs about as much and is a bit taller too.

He only got in one race using the WGT last year but it seemed to work well. Maybe it's OK for the price but then you need to drop another $20 or so for the programming box.
