MTH #55 Airplane Controls

That would be very cool!

  Tiny motor for a micro park flyer perhaps? Although they’re DC, there’s probably an equivalent AC motor out there...All Electronics maybe?

  This diagram might clarify.

I would look at introducing some form of voltage controller with a potentiometer into the power supply to the plane .. that way you could easily set and forget , but also have the ability to make full use of take off and landing if you want to play ... apologies in advance if I am missing something here as I have no experience with these units at all

Does it HAVE to be AC .. I would think it would be far more economical for them to use a simple DCmotor in these units ?

If DC then something simple and cheap as

Checked with a buddy who was an factory-trained service (until the shop he worked at closed its doors) and he says that MTH has very little info as far as servicing the #55 airplane and zero spare parts.  Sadly, I think this is more and more common with Chinese manufacture, especially the spare parts.

Anyway, I opened up the base of the pylon and did some snooping.  It appears as if the 14 vac supplied to the terminals powers a DC power supply which provides DC to a small motor.  I removed a few mechanical items (there are a pair of springs applying a crude mechanical brake that is pulled away from a hub when the power would be applied via the control stick) and cut the wires feeding the DC motor.  I need to pick up some hookup wire.  All i need to do to complete the conversion is to runs wires from the motor to the terminals and the airplane can be powered by a spare HO power pack.  I will try to take some pictures of the works once complete.

Thanks for the suggestions,

Tim
