Just got some more detailed info on this pack while i was at work today.
The pack its self is made by a company called FLIGHT POWER who have been making batteries for planes and helis for a while now. One of their packs powered an electric helicopter to victory over a whole field of IC helis in the uk 3d championships earlier this year.
The person I spoke to today didn't mention anything about cell matching and they have never matched a flight pack before so I don't think that part is true. but they did confirm that it will be released in the uk in the next few weeks and has a retail price of £78.00.
Don't you worry, next time I'll win for sure. For I have a cunning plan.
