Hi guys,
I'm pretty sure this one has been asked a million times, however in my search i can't find where it's discusses on here.
I'm going to get my first glow engine (trying bigger than electric planes for a bit see if i like it) but I can't figure out which glow plug i need to get
the engine will be an OS LA40 or Tiger .46 what do i get? #8 long, short, cold medium heat or hot glow plugs? too many options I'm stuck
I live in the tropics and tempretures over here are around 27-32C (80.6-89.6F) most of the time sometimes slightly higher by one or two degrees anyone got any opins on this?
sorry if this has gone round here too many times to count but I'm in a bit of a rush to make an order and can't spend a couple days digging into the forums properly.

Thanks for any consideration guys.
