After my old engine from the 4094er set stops working properly so I bought it and tried to install. Unfortunately, he has only one recording knobs below and some pole shots. With a row of studs above it would be much more flexible. But he DEHT with decent performance, so that the small driving animals to the delight of my son go back to the Tepich.
1 point deduction due to more limited knobs equipment and especially because the cable is quite short (and no longer compatible with the old)
