Honey bee king 2/Belt CP radio

[lalalandrus]

I am dirt cheap so instead of buying a 9 Channel TX, i re-purposed the tx found for the belt cp/honeybeeking 2 from esky. i also went one step further and made it do ppm sum!

TX - Esky 0406A
RX - Esky Ek2-0402A

Tx mods - on the back flip the red dip switches to 1 on 2 off, front switches ail, ele, thr = norm, rud = rev



RX mods - PPM sum is obtained from first pin on U3. i cut the trace for the B port and soldered it to that pin. see pix.
