T-Hawk Battery Replacement?
I have a T-Hawk,Skyseeker and Predator.Planes good,batteries ehh.Could I go to li-poly or something else.Is there an all in one wall charger to go with these better batteries.What is the tool needed to check if the batteries are fully charged?My T-Hawk has crashed on launching several times with batteries that were supposed to be fully charged.current batteries are labeled KAN 7x2/3a 900mAH for T-Hawk and KAN Ni-MH 7.2 v 6x2 600 mAH for the other 2.What about adapters if the new connections are not Tamiya heavy duty standard.I appreciate the help,really!
