Skyfun Motor Choice

Posted by Ryan on May 21, 2011 at 3:13pm

I just got my skyfun in from HK and after my first flight I can definitely say it's underpowered. I've google some motor upgrades for it but they all seem to have 1 thing in mind...speed. I want to throw my APM in it so I dont need or necessarily want all that speed. I'm wondering what some others have done with this airframe and made it a successful UAV.

 

Thanks for your input,

    Hello everybody,

    My name is Alain, from France (my apologies for any grammar mistakes, and luckily you can spare the outrageous accent).

    I'm working on a personal project, involving a Skyfun (already playing around with a Multiplex Twinstar)

     

    The more I'm reading about motor choice the more I get confused, so here's my plans:

    On the Skyfun, I am planning put:

    the APM mega + airspeed sensor + xbee+ gps (+ off course receiver and servos)

    and a Gopro.

    I'm not necessary looking for high speed flights, if I get up to 100km/h (55Mph roughly) that would be more than enough.

    After many hours losing myself in different forums and comparing different option:

    I come up with this combination:

    this engine: link (I have also think of that one but not quite sure though: link ) with a 60A ESC and a 3300mA 3S lipo

    Do you think that will do the job?

     

    Thanks in advance

    Alain

    PS: Still not sure about the prop though...

    I have flown several SkyFun with ArduPilot/APM and found the (GL/BP/BL) 2212-6 to be a great motor choice.  Plenty of power for this application and pretty inexpensive ($15-$20).  Looks like my usual suppliers (Grayson hobby, BP hobby) are out of stock, but you might find one around somewhere.

    A huge range of motors can be used on the skyfun. I have run a Turnigy 2836-3700kv, Turnigy 3542-1450kv  and even a Rimfire .32 800kv but most of these were for speed 140km/h +. For a moderate power upgrade something around the 30mm size and a kv of around 1400-1800 would be good.
