One source of small and readily available motors are the ones fitted into servo's. I used two of them for propulsion on my model Revel U-boat and they work very well.

If I remember rightly mine were 16mm diameter but there are, of course, micro servo's which must have even smaller motors.

Google a model supply company called SHG, which is where I got my bits from but I'm sure there are a lot more suppliers that could help.

As for issues, one thing may be that you would want to get to them for lubrication or removal purposes but there again the old Airfix 1/24th motors were glued in for good. They obviously didn't require cooling and I'm sure that turning a 1/72nd prop will require such little current that you won't have any heat issues.

Now if you wanted it to take off that would be different!!!
