Lighter for? It will not give you much savings on the AUW but then you may end up having problems with CG. Remember, your Lancair's rx batt is way back there. For me ... go with a 90 sized 2C, its more powerful than a 61 which I feel is not worth getting. Costs not that much less but for the same weight you are not getting the performace of a 90 sized 2C.
