Then you can experiment and tell us.
Bring a bunch of Hand Warmers, http://www.industrialsavings.com/har...FUmd4AodsnkAaQ
Place them around the electronics and use a FC that does not need a compass. If you can choose your flying days, only fly when it is calm, then there is no need for the Z15. Try the HoverFly Sport board, it is very stable.
In that environment you want to keep it simple.
Good luck and keep us posted.
