I might grab one to put in my 1/6 KV-2 project to play with since I already have a Vantec RDFR38E ESC for that tank. The Vantec already does dual channel mixing, but I think it can be disabled with a jumper to let the TCB control it. Otherwise I think there would be issues if I couldn't turn off the channel mixing. Of course I could still test it using a set of IFI 883 Victors instead. Then I could eliminate my IMX-1 channel mixer I have for those.
I guess not right at the moment...seem to be sold out. Status is backorder.
