the open standard interface on the FrSky 2way Rx is a great invitation
to come up with creative add ons.
I agree with Bruce about the danger of looking away from the model in
order to check a display on the Tx.
Top of my wishlist is an audio variometer for gliders. I have looked
at a lot of commercial (way too expensive) and home brew gear (not all
the features I like). Also it always involved a separate Tx/Rx return
path for the information, not an ideal situation for small gliders.

So the possibility to have it all integrated into the RC system is
VERY appealing.
There are some really cool digital pressure sensors available that put
the old analog Motorola pressure sensors to shame regarding
resolution, noise and size.
For example the BMP085 from Bosch.

Or, wildest idea yet: integrate the sensor into the Rx! That ought to
be a first on the market: a special glider Rx with integrated vario.
What do you think?
