Yes LiPo batteries are on the list of things I need to get, when I have the money after paying off my credit card bill
My plan is to use a 5S4P TP 8200 mAh battery, two 8 min flights on one charge is very interesting. But the FAUP's will have to do for now as the cost of LiPo's is to much right now, maybe I'll ask Santa if he has some batteries for me?
I've looked at your thread and if you have the money for it, the setup recommended by Daniel Schubeler would be a good match for your airplane. Looking at the Plettenberg website it is listed for 21 NiCd cells ( about equal to a 6Cell LiPo pack) giving you about 2300 gram of thrust for each fan. It should give your Me262 good performance and a flight time of 8-10 minutes.
