Revell 1/32nd Eurocopter EC 145

It has been an ambition of mine to try and motorize a scale helicopter kit but haven't yet done so. As far as I know 1/32 seems to be the largest scale for a helicopter kit at present and logic would have it surely that the larger the scale the less figity it would be to install some minor piece of motor engineering inside. I love the look of the Revell kit of the Eurocopter 145 in Swiss rescue livery, and it's this kit I have in mind for motorizing. Has anybody who reads this entry tried to motorize the aforementioned kit or similar? Or could anybody please refer me to some material, be it printed or on the Web, as to how I might motorize a plastic kit of a helo? I realize that in order to try and motorize a kit I might have to sacrifice elsewhere such as on interior detail, but it would be a thrill to see the rotors turning.
