Title: Should I use PPM with Devo 10 (deviation) and CC3D (eventually Revo)
Post by: n8huntsman on March 25, 2016, 06:31:17 pm

I'm building my first quad. Starting with an eachine flacon. I have a Devo 10 and RX1002. I'm putting Deviation on the Devo. The falcon comes with a CC3D which I plan to use for a while. Eventually I'd like to swap it for a Revo, oplink, and GPS.

For the time being, would it be beneficial to use the RX1002 then swap it out when I upgrade to the Revo for something that does PPM?

Or is that a waste of time configuring deviation and just bite the bullet and swap my RX now?

Any obvious pros and cons to PPM with the above setup?

Recomendations on an RX?
OrangeRx R1020X? It says,
• 10 Channels PWM
• 9 channels CPPM

Is that (10 PWM + 9 CPPM) for 19 possible channels or 1(0 PWM or 9 CPPM) for 10 max channels?

If it's (and) maybe better off getting the OrangeRx R410X since my TX only has 10 channels anyways?

Thanks

Hi,

You should use a small form factor receiver, using PWM input board only support 6 inputs.
No need a big receiver with 10 PWM outputs on a mini 250 sized quad.

PPM is better, less wires and small receiver can be used.
Also that allow OneShot or PwmSyncr output (depends on Esc you use) that give better results with a quad.

Thanks for the quick reply.  My esc's are Fairy-20a which allow OneShot.  So it sounds like an OrangeRx R410X is the way to go?  Or would a OrangeRx R615x be better?

Sadly looks like both are limited to 6 channels cPPM :(
This means you cannot get two knobs/pots for tuning...
