Great just what I need, a thread for helping glow people move into gas. Thanks for all the info so far but I have another couple of questions. You mentioned a choice of using the main receiver battery or an additional one. What would be the smallest battery you can use for the ignition and can it be a small Lipo? Also with the kill switches is there a particular type to use? How do you set up a kill switch through the radio?
I'll probably think of more questions so I'm giving you fair warning Lol
If you are limited by space or weight you put the largest capacity battery in for the ignition that will fit . The larger the milliamp(capacity) the more flights you will get before the ignition quits. The ignition for the engine will limit what voltage(s) can be used. Older ones may only use 4.8v while newer ones can support 9v. Some like to use regulators or diodes to drop the battery voltage for ignitions that can't handle higher voltages.
A mechanical kill switch can be any good gold plated switch with or without a charge jack. Reciever controlled kill switchs are made by a few manufacturers. You connect it to a spare channel and program that channel to a 2-position switch.
Read through the linked post in the second reply above.
