Default DO THESE JR R921 DATA LOGGER NUMBERS SEEM OK??????????

Just did an advanced range check per the JR X9303 manual, http://www.horizonhobby.com/ProdInfo...Res_Manual.pdf, page G-22. Receiver is an R921 with 12" extension to the satellite receiver.

First check per step 5 holding the model in various postions: A-23 B-9 L-3 R----(only one satellite receiver) F-26 H-0
Next the model was rotated horizontally(rotating on the main gear in circles sitting on a wooden table) A-3 B-0 L-1 R---- F-15 H-0
Next the model was rotated on its spinner atop the wooden table A-8 B-1 L-0 R---- F-22 H-0

This is with a 60 size plane with a tuned pipe running above the servo/radio bay and the receivers in close proximity to the servos and control cables/wires. These old retract gear, piped engine pattern planes are very cramped in the radio/servo compartment.

All the fades in the first check were when the tuned pipe was directly between the transmitter and receiver.

I think this check should be acceptable. Any JR experts want to give an opinion?

Those numbers are fine. The most important number is no holds. Try some flights with the data logger and compare the numbers. I have recorded up to 35 frame losses in flight and never seen a hold recorded.
