R/E/A/A/F/F = 6 channels
Throttle = 7 channels

Using a PPM receiver you have 8 proportional channels so you have one left.

For use as a camera platform I would use the aerobatic profile rather than glider profile, leaving your throttle on the stick. You are probalbynot going to need the glider mixes if you are really flying it more as a camera platform than a TD glider. It will still glide but you won't have some of the camber settings that TDglider pilots use. But you probably won't care.

Using a PCM receiver you also have Ch 9.Ch 9 is on/off.If you just need camera on/off or shutter trip, then Ch 9 could serve that purpose nicely and you still have variable throttle. Again, if you use the aerobatic profile you can keepthe throttleon the stick and put flaps on a side slider. You don't needbutterfly, use flap to elevator mix for landing mix. Put it on the left slider.

If you are more interested in the Cularis as a camera platform than as a competition glider, then you should be just fine, however there is nothing wrong with putting the flaps on a Y cable and freeing up achannel so you can fly using an 8 channel PPM receiver. You could Y the ailerons tooif you need anotherextra channel.

I fly a 9C super.
