    Pilot Pete’s service is outstanding – rapid shipment, good price to start with, good products. And a surprise gift in the package, which turned out to be just the answer to a problem I’d been wondering about – a LiPo battery tester and alarm.
    Cheers Pilot Pete – top marks all round!

    Really good quality BEC, and I got a neat little glider from my package too which was nice
