How many hands does this guy have to operate the model, and how the heck does he remember what all of those functions are for??
I think we may have strayed a little bit further than Octo needed

Octo - My advice, for what it's worth, would be as follows:
Avoid 2 channel > poor VFM, and you'll soon get fed up with its limitations.
While the Chinese sets are superficially good value, I have technical issues with all of them - chiefly around poor QC and the "floating neutral" values (and the restricted throw on the throttle channel).
I would recommend buying a Futaba, JR, Hitec, Robbe F-series or Spektrum DX6. All are "name" brands with established reputations and UK service agents. Save the budget sets until you know more about the whole scene.
BTW how big is the prop recommended for your coble? If it's the 36" long hull then perhaps a Speed 720 Torque motor on 12v with a 40mm 3- or 4-blade prop would be the way to go. For a nice, slow trundler on a sheltered pond then a 555 motor and a 35mm prop would probably do (cheaper!). PM me for further info if you wish.
