Unable to PM yet as I've not posted enough here. But if you PM me then I should be able to reply?
Yes I kind of dropped the ball on the STUG stuff, but once I recover from my hand surgery (long story) I'll talk with you and get that sorted.
2.4 gHz sounds great, but I'm trying to make the most of my existing HL stock for the moment, so for my three WWII tanks stopping and firing is just fine and so Dragons will be perfect for these, although I'm not sure about green coloured boards though, as these might clash with my bright yellow batteries

As for the Leo, I've already ordered the RX-18 but am open to other solutions if not too costly, I have even looked at the Clark board, but using duel RX-18s would give me the ability to fire on the run with no track recoil, may even be able to use a single RX-18 to only run the motors an see what parts of the existing VS board can be used in parallel to run the rest? Cant seem to find much info about modding the VStanks in this regard, but may just be looking in the wrong places.
