    I remember Geoff doing a mode to a voltage regulator inside the spectrum which saves 50% of the battery life so it runs longer... but this does void your sprectrum warrenty....

    I beleive the pack in spectrums is about 600mah or something like that?

    For £15 from Model Power i got a 2100mah pack and runs so much longer, and does not void your spectrum warrenty.

    You will get around 4-5 hours run-time with the standard battery pack. If you want to go the whole hog, also change the stock battery pack for one of these from http://www.modelpower.co.ukwww.modelpower.co.uk ...

    (dont forget to order the new pack with the spektrum power plug!)

    You will then get around 8-9 hours run-time!!!

    ok. can these new regulators be purchased from the UK? also it says to remove the old one you nedd to heat the body is this what you do to fit the new one?

    may have a few more questions after this, to see which would be the best choice for me

    thanks alex

  8. ok thanks for that, just thought if it only uses 3.3v why does it cut out around 8.4volts? am i missing something?

    is it because when it converts it down it would be to low to run it?

    thanks alex

    (told you i would have more questions!)
