Does anyone know whether a couple of my chargers (hobbico 900 and Towerhobbies 400 quick charger) are going to be able to charge nimh receiver packs even though it doesnt say anything about nimh on it?

I might try it just for fun!

If it doesn't come with the needed connector you could just get a Tamiya to Receiver plug cable.

I ordered the correct adaptor for it I just wondered if anyone tried to charge their nimh packs with a nicd charger. is it safe?

They would probably be ok on large RX packs made from suB C cells.
