I have one of the Corona 2.4 DIY kits. Is there an advantage in removing the shrink wrap on the RF module for additional cooling or is this a bad idea?
Cheers

All of my Corona TX modules, Futaba type and DIY type have a chopper regulator. This is a switching regulator with a soft start. The power source I'm using are 3s batteries, the TX modules operate at a very low temp.

It shouldn't make a lot of difference and if you remove the plastic you may run the risk of shorting out other bits in your transmitter if the board comes loose.

An option you can use if you want to reduce the heat produced by the module is to add an external (to the DIY module) regulator that drops the main transmitter voltage down to just 7V or so. That'll let the DIY module run cooler if you're worried about heat - but it's a lot of extra work really.
I haven't seen the FrSky DIY module yet but I know that their transmitter modules use a switching regulator that not only keeps them real cool but means you get *much* longer operation out of a single charge.
If folks are interested I'll do a comparison between the various DIY modules to look at the pro's and con's of each.
It might be worth starting up a forum where people can upload information about their own DIY conversions so that others can benefit from not having to reinvent the wheel. What do y'all think?
