PlaneCrasher66

Hi all. This is my first post. I recently acquired an old F/A-18E made by interactive toy Concepts
Air Rage decal is on the controller.
My problem is it did not cone with a battery.
on the underside of the wing it has the battery specs. I have been looking foe a NiMH replacement, but no luck so far. So i am wondering if i can use a lipo instead?
4.8V (DC)9.6W Battery: 1X4.8V NiMH rechargeable battery. This is what is on the sticker. The plug on the plane is a mini female tamiya.
thanks in advance!

I hooked up my aerobird NiMH battery just to test...works great. Battery is too big for f18.
Ok, so I made a connector to use to test a 3.6v 500mh lipo. Turn on plane and prop runs full bore!
so apparently can only use NiMH? Idk..why would it do that?
So I ordered a 4.8v 1500mah NiMH battery. I'll just have to change connector or make another dongle. Not sure how to attach it to the plane as it is bigger than the slot.
any advice would be great
