Minima 6E, 6T Receivers & Optima Lite 6 Transceiver - Minimum Weight AFHSS RX

And I think that it will be still heavy, after disassembling the plastic box. Does anybody run in
to this issue? Is there a solution or I have to wait until such micro Rx will be available?
If it will be available someday. Thanks
Minima 6E/6T Micro Receivers. ("E"nd and "T"op connectors as pictured below).
Were due March 2011, re-scheduled for June 2011.
These weigh 6g with the case and 4g without.
These are non telemetry RX but with full range.
There have been some question why this has dual antennas when the Optima can use only one BODA?
The simple answer is that they are two different animals. Any time you build something that is lightweight
you have to make sacrifices but Hitec were unwilling to sacrifice full range thus dual mini BODA's.

18 April 11:
Spectra Module V3.01 now available - update required for use with Minima RX.
Minima RX (non telemetry) can now be released and used with Spectra 2.4GHz modules which have been upgraded to V3.01.

07 July 2011: Update
"Minima's just arrived yesterday and are shipping to the distributors this week.
They are completely different RX's than the Optima's.
They use two Mini BODA and while they did work fine with only one, we used two for maximum performance and full line of sight range.
No, there is no Data or SPC ports but the minimum operating voltage is 2.6v vs. 3.5 for the Optima's. - Mike. "

. Optima Transceiver Caseless Weights
Optima 6: 7- 8 g
Optima 7: 9 - 10 g
"lower weight is without the BODA. - Mike."
