RE: JR Spektrum 2.4 conversion "Module"
I too was worried about flying and losing contact with a less than tight fitting module - contacted Horizon and this was what they had to say (Actually, I've flown it for a while since with absolutely no problems)
Hope this helps with peace of mind....Mike
"Thank you for contacting Horizon Hobby.
The lengths of the contact pins are more than long enough to ensure complete contact as long as the module is in the transmitter. We have never heard of any situation where the pins lost contact resulting in a loss of signal.
Again, thank you for contacting Horizon Hobby, if you have any further question, please feel free to contact us again.
