does anyone have OI and RC radio issues

Nope. Without knowing more about their link budget, it's not immediately clear which should be which.

Judging from the photos and clever use of MS-paint, the internal antenna is roughly 1/4 wave, and the external roughly 1/2wave for the 902-928MHz band. Assuming no poorly placed metallic structures, and that you aren't purposefully pointing the antennas end-wise at each other, you should get a nice fat pattern off both. Once again, for the interested reader, RFCafe has lots of fun info about antennas, power, patterns, etc. IN particular, check out http://www.rfcafe.com/references/ele...a_patterns.htm

I've got to hand it to the IFI RF guys though, they tuned their transmit strength to be JUST under the FCC limits. Particularly on the RC side If there is a signal strength problem, it's not on the transmit side.

I'd say those are my 2 cents, but at this point I'm up to about a buck's worth.
