What I am seeing, is that many of the newer ARF offerings are really light. The Top flite FW 190 for example. So you have to get it even slower.

First I purchased a Weatronic Tx module and 2ea Micro 12Ch receivers. The air speed sensors were hard to get and very expensive so I purchased a Taranis 16Ch with 3ea 8Ch receivers. I intend to test putting the Weatronic Tx module in the Taranis external slot and using Weatronic for the primary controlls and the Taranis Tx with the 8Ch receiver for additional controls and for telemetry. I have an air speed sensor, an altitude sensor, a GPS and a secondary voltage sensor. The Taranis has built in telemetry for receiver/servo voltage and RSSI.
I didn't like the soft stick centering on the Taranis so I made metal centering arms and worked out very good. I still feel the Weatronic RF link is better so that is why I want to use it for the primary controls. I think the Jeti is a comparable RF link to the Weatronic.
My Taranis air speed reads in Knots. On my Shoestring I did a stall test at altitude and it stalled at 31 knots. On landing the Shoestring I can hold it off touch down to approx. 27 knots. My conclusion is the difference in stall at altitude and the 27 knot touch down is ground affect.
If the price of air speed for the Jeti is reasonable I would get it right away.
