I would advise fitting some kind of insulator between the ESC and receiver if possible, if the receiver gets too hot then you may run into some issues. Foam rubber may work just fine.

As far as mounting the antennas, any 90* orientation you can make work will work just fine. Most guys I see around the slopes here mount them in a "V" shaped pattern atop the fuselage up front. The system won't be bothered by any noise created by your ESC or motor, just so long as the tips of the antennas stick outside of the fuse.

I have others with full carbon fuses where I just drilled a small hole for the 1/2 tip of the antenna to stick out. I did not put it in a tube at all, I just pushed the antenna out the hole and taped the boda to the inside of the fuse so that it would not move around.

Both of those setups have been rock solid for me.
I've been running an Optima 6 receiver in my gliders for several years. Both have fiberglass fuselages and there has never been an issue on control.

Im going to take the nose section off at the weekend and see if i can locate the rx underneath the wing section and then make a small bracket to hold the boda bodies at 90 to each other but at 45degrees to vertical.
Many thanks for everyone help and i will hopefull put up some pictures to show the final layout

Same here. I usually run one down the fuse towards the tail and the other towards the nose with the uninsulated end taped down at right angles. Never had a problem running them inside foam, plastic or fibreglass. As far as I know this is a diversity system with the rx using the antenna with the strongest signal. I still use a Minima 6 that had one antenna ripped out in a crash and haven't had a problem.

The Optima 7 only has the one antenna and I've never had a problem with running that down the fuse either. Just don't stick it where the battery can get between it and your tx for any length of time..

SPC Port failure

Spc cable is soldered to esc connector.
Reading Alans Hobby model & FAQ web links.
Re spc port "Be Carefull, reverse polarity will damage Transceiver."
The spc port uses a keyed servo connector. Very easy to get reverse polarity here if using a non keyed connector. Yes i have at times used a non keyed connector for spc port, my bad.

lexm is not talking about reverse polarity connections. He's referring to multiple ground/return paths.

Hi

I just took my optima 9 receiver out of it's case to make it smaller for a mini quad, so I shrink wrapped it up.

Now I've tried to power it up and it's dead - no LEDs come on at all.

I could have sorted the antennas or over heated the board - is there any way to resurrect it?

Many active components are heat sensitive. It depends how hot they were. But if they were too hot there is no way to resurrect them.

Make sure that the shrink wrap is not holding down the bind button. I know I have had that problem in the past, although I don't recall how the rx reacted to it.

Yeah I've since taken the wrap off to troubleshoot and the button is OK

Seems like it must be the power regulator as nothing lights up at all on the board.

Are you powering it via SPC?
If you're powering via servo connector, do you have the SPC jumper on?

what am I missing? thanks!
