Lew Weaver, Thanks for your helpful reply. Sorry I thought it was from Tony. I am surprised that you are using 2s lipos rather than 3s. Was this to keep the overall current down? I was talking to RCDirect and was advised to use 3S. However,you say you had good performance with 2S. I am still contemplating changing my setup from speed 400s with gearboxes to brushless with Nimh or Lopos. I found my Lanc balanced well with the 2 packs of 8cell Gp2200 Nimh and would like to know whether you found it difficult to get the CoG right with the much lighter Lipos Regards, Malcolm
