    Hi Guys,
    Recently I was away on a vacation and while reading my 30 some airplane magazines I brought I saw an add for this little plane. https://sawncraft.com/products/cherokee-24-kit I decided to build my own but on returning home and googling a bit I have had no luck with finding the electronics. I don't want to spend a fortune on a micro plane and was hoping to build on with a budget of about 30 $ Actually, as iv been writing this and looking online I have found a few electronics that look promising. https://www.banggood.com/Racerstar-...tproducts__1&ID=49005522421&cur_warehouse=USA
    I am envisioning a 10 in wingspan give or take and I'm not sure if that motor will be enough.
    Also, I am going away in a week so I would like to have an airplane to take or at least be able to ship some electronics to my destination so I can build when I get there. I also don't know what prop sizes I will need pushrods etc.
    If anyone knows anything about these microelectronics and where to get them please let me know

    Thank you,
    Matt

    Hi,
    It seems that micro aeroplanes are just like other micro systems. The smaller you go the more expensive they get.
    The main problem will be a micro receiver and servos. Unless you can get the electrics from a busted up micro plane , you may be spending a$100.00 a least.
    Depending on what system you are using Spektrum , Frsky....

    Ok, those look good all I would need would be batteries and a motor correct? Also pushrods etc I am using spectrum. :)

    That should do it.
    The suggestion by hwilton is very good.
    You could use carbon rod for push rods or Tig wire even combine the two.

    Ok, so I have some electronics picked. If I use this (https://www.banggood.com/Oversky-MX...HSS-p-1332998.html?ID=554812&cur_warehouse=CN) as receiver and servos is that also esc? Now for the motor, I am not sure how to pick the right motors. I think I have 2 options here what is the best and why(https://www.stevensaero.com/product/pkz3624/) (https://www.banggood.com/Coreless-R...toys-and-hobbies-US&ID=46057&cur_warehouse=CN) I'm trying to build something that I can fly in the house if possible. Any other information anyone knows would be appreciated. Also I'm not sure if all those connectors are compatible so If anyone knows please let me know.
    Thanks for all the help and feedback!!
    Matt476 :) :)

    I`m a bit out of my depth with this micro stuff, but I would go for the banggood motor combo if it is brushed, which it appears to be looking at the motor wires.
    The Oversky MXL-RX62H V2 Receiver Integrated with Dual Servos for Frsky DSMX DMS2 FUTABA SFHSS should give you all that is needed for a small indoor model.
    They all work on a 3.7 volt lipo and that is what you will need to complete the electrics.
    These 1s batteries are very cheap and can be got from banggood.
    Please don`t blame me if my assumptions are wrong but that is what I would go for if I were to build a small indoor model.
    There is a very good chance you will need to solder some connections and make sure you order the correct system (spektrum) DSM
    Cheers,
    Ian.

  15. Well it states it has two outlets, one for brushed and one for brushless.

    The MXL-RX62H V2 Series receivers is a new compatible receiver for mini aircraft. It integrates with 2 linear servos, 2 independent output interfaces, one built-in 3A brushed ESC output interface and one brushless ESC signal interface.

    Ok so I'm a little confused this is a receiver and 2 servos. I see the 2 ports for the motor is that all I need? Thanks for all the help guys I'm terrible at picking the correct electronics lol.
    https://gyazo.com/daff5a1b245b405e4196b6f6034be3e3 Also does anyone know how the binding proses works on theses?
     
  17. From what I can tell from the picture, they are showing you where to solder your two motor wires. The two empty ports well one is labelled for an aileron option and the other is the bind plug, I would assume but don't quote me you would need a plug that basically grounds the terminals together to put the rx into bind mode same as a normal receiver and more then likely the same process. it is a receiver with two linear servos, in the left picture those 2 motors and that part beside it are your servos and you control wire will attach to it.
