Corona RX
Guys.
Do you guys able to use 5 cell Nimh nominal voltage of 6V with the corona rx on CR3D-2?
Thanks

Corona DIY transmitter Binding QUESTION
Just returning to R/C after about 20 years, also new to electrics.
Purchased a Corona 2.4 DIY conversion from a Fla supplier. Came with scant instructuions and NO SUPPORT, (just rude comments by e-mail) .
Three questions:
!. Says that if the Xmtr bind button is held down more that 3 seconds, the ID will randomize. Since what can happen, will happen, (hasn't yet) how do I regane functionality if I inadvertantly trip up here?????
!!. Says to set failsafe, place transmitter failsafe switch in position and press rcvr bind button. What does this mean??? Do I place all transmitter sticks where I would want them should I loose link with the receiver, or is just the throttle, or is this something else?
Also for this step, do I turn the receiver on before or after the transmitter???
!!!. While on this, If it is just the throttle, Which channel is considered the throttle channel???? (It used to be Ch 4 in the old days).
!V. And lastly, the receiver has 2 antenna wires. How should they be arrayed??
In the old days of one antenna, it was common to have it exit behind the wing and go towards the top of the tail. With two, would one be as before and the other towards one wing tip, or is there a better way such as one going towards each elevator end???? I understand to keep them away from metal and that things like the engine will shield the antenna (ie., VERY line of sight).
Thanks in advance, I have further questions about electrics for later.

I am not really sure what it means if the ID randomizes but if it does I would just repeat the binding procedure. Do you have this piece of gear installed yet? Did you find your PPM signal out of your transmitter?
How long is your receiver antennae. If it is short I would just use a small aerial and stand it up.

Corona DIY 2.4 conversion
Not installed yet since I like to have most questions answered befor heating the soldering iron.
BTW, in another post I noticed a question about soldering the antenna to the board. The pad labled ANT is for the center conductor of the antenna coax while the larger pad is for the shield. If the coax is used without "grounding" the shield, the shield also radiates which MAY reduce the range or even overheat the transmitter.
The PPM line is not hard to find on HeathKit transmitters since it goes through the buddy switch, besides, I have the building instructions so full schematics.
The antennas that were attached to the receiver (2 of them) are about 8 inches long.
Any ideas about the correct order of powering up? Both normally and when setting the failsafe function???
