    This 2847 is definitely not suited for our hobby!
    No cooling holes, gets awfully hot in a no time.
    Tested with prop APC 7x5 or Kyosho 7x6 etc. and lipo 2050mA 20C got 200-220Watt at 20-22A, which is a must for any small and fast plane. Motor weights 134g, too much relating to performance.
    You better buy one with cooling holes at www.4-max.co.uk, not as cheap - but it works!!

    Nice performnce in F18

    Sep 11, 2008

    Good performance in F18, with EDF Ducted Fan Unit 7 Blade 3.5inch

    Pulls 24Amps static on 4 LIPO cells

    The only problem was the external diameter wich was slightly more than the specification, so it entered very difficult in the EDF
