PPM Encoder

Is it OK to use a PPM encoder or should I just keep it simple and buy a receiver that is modifiable?

Thanks!

PS
Great project! I've been sitting on my Gluonpilot for almost a year now but hope to have something flying this winter...

You can connect each channel from your receiver separately - PWM. This option doesn't require any encoder nor a tapped receiver.

Yeah, I was looking at that as well.

Just thinking down the road when I may need more than the 5 channels (doubtful) or go to a 2.4 GHz radio but just ran across the PPM encoders over at the Paparazzi website.

The encoder will work but adds a level of complexity that isn't really necessary. Receivers are so inexpensive anymore that buying one to tap is almost as inexpensive as the encoder! You can buy a 3 channel receiver, tap the ppm, and all of your transmitter channels will be available.

There are now a few 2.4ghz receivers that can be tapped also. Frsky is manufacturing one that already has an external connector for PPM! Been waiting for that!

Great, thanks for the info! I'll have to look into that. I didn't realize I could get all the channels with a 'lesser' receiver.

Still much reading to do...

Thanks Mitch for pointing this out! This is the receiver with PPM-output:

If you wish 35/40MHz receivers with PPM, you can buy one from ACT (or hack one yourself)
