esky heli radio specs: FM PPM
Does anyone know what RC coding the E sky helicopter uses?
The transmitter says: XTAL, FM_PPM, 4 CH, 72.810 MHz.
Does this mean it's:
Single conversion / Double Conversion)?
(+/-) FSK (frequency Shift Keying)
After reading a site about the workings of RC coding techniques (like PPM, PCM),
http://www.torreypinesgulls.org/Radios.htm
I've decided to use the Esky transmitter and a new 4 channel receiver to put into an EP aerobatic plane I just got off ebay.
But before I can get a 4 ch, 72MHz receiver I need to find out whether the esky uses:
1) single/double conversion
2) positive/negative FSK
3) whether a 5+ channel receiver is OK w/ a 4 ch transmitter (the above mentioned site has lead me to beleive so).
Thanks,
Daniel Korytina

RE: esky heli radio specs: FM PPM
If the transmitter uses PPM then you can use any brand PPM/FM receiver tuned at 72Mhz and any number of channels.
The Receiver crystal is matched to the receiver whether dual conversion or single conversion and even the brand (this has nothing to do with the transmitter besides the actual frequency which obviously needs to be the same)
PCM on the other hand needs to be matched to the brand and type of transmitter however it is much more reliable...
