Modification of Graupner MX16s to JETI System (35 MHz – 2,4GHz switchable)

August 10th, 2010 by Speedy Leave a reply »

Some weeks ago I decided to buy a new remote control for my Mikrokopter(s). I took the standard model (MX16s from Graupner) which is recommended for Mikrokopter pilots.

At the same time I had to think about 2.4 GHz remote control – But I would like to have the choice between the two frequency bands (35 MHz and 2.4 GHz) so I modified the MX16s 35 MHz remote control with the JETI System to have the ability to switch between 2.4 GHz and 35 MHz at any time.

So I can use 35 MHz for FPV flights and 2.4 GHz for “normal” training or fun flying. (Maybe I will buy a 5.8 GHz video set in future, but that is not a requirement in the moment.)

Below you can find step-by-step pictures of the modification of the MX16s remote control.

Good luck with your modification and happy flying πŸ˜‰

    First of all thank you for this useful article. I have a Graupner MX-16S 2.4GHz set with Jeti. I’d like to have 35MHz for FPV flights as you mentioned. Do you think what I have is a modified 35MHz (upgraded to 2.4GHz with a Jeti module)?

    Thank you πŸ™‚

    I don’t know, you have to open the transmitter and compare your electronic to the photos of mine.
    If they match, then you are able to install a switch according to the description above. (Maybe you will need a 35MHz antenna)

    I have a Graupner mx16s 40/41mhz

    How much expenses to make a switch for 2.4 GHz

    Where I have to send the Transmitter ?

    Thanks for replay Alex Lageler

  4. Whoa, it’s just great. Could we build my own? how much it will cost?
