Looking at new transmitter

[Tilly]

Hi guyz
A couple of people spoke to me the last friday, Danny was 1, about upgrading my Ansmann W5 transmitter to 1 that has setting options that would allow me to reduce the power of my motor to stop it being as punchy.
I've had a look at a few but to be honest didn't really know wot i was looking for. Modelsport have the Ansmann W6 on sale at the min at £45 instead of £80 but i didn't know if this is wot i should be looking for.
Any help or info would be appreciated
