Hi, whilst not a beginner, it has been a few years since I took up the modelling tools. Having now retired I decided I would re-enter the world of model boats and dug out some old hulls and radio gear. Hulls no problem, as nothing much has changed, however, after a bit of research on the radio side I discovered all had changed and the key phrase seems to be 2.4 Ghz! Having read various reviews I believe I understand the advantages of these new 'binding' capabilities but could do with a little help on the basics. 
So if I may pick some brains with a couple of questions before I send the kids out for my birthday presents.
What are the most suitable transmitter types for 6 channel boat control. (The aircraft ones seem awfully complicated for boat operation)
Can I use the 27Mhz Servers, (of which I have dozens), with 2.4 Ghz receivers. Sorry I really am ignorant regarding the details of how the electronics work.
Any help will be greatfully appreciated, Gary
