I'll try and keep this short. A fellow joined our club the other day to learn how to fly. told me he had all his stuff. i went over it on sunday and changed things that needed changing and test flew and trimed the plane. We were to meet on Thurs. night to start lessons.
On thurs. night ask all the right questions about charging and had someone else trim the plane on the buddy box.
He was doing well until he got the planes up-side down as i was fixing it and turning the plane away fromthe run-way,i lost all radio control and the plane went in.
some at the field felt that i had lost it and gave me a hard time in teaching because i own a LHS.
I have a hughesrc cycler and charger, and put his rec battery on it. On the first cycle a 600ma battery only went to 107ma. The voltage was 4.5. these batteries were over 3yrs old and have never been charged. I'm now trying to cycle it hoping i can save the battery.
Just because you charge the battery over night, doesnt mean you have a full charge. They be must be cycled on a regular bases to know if they can hold a full charge.
also some at the field should wait until all the information is in before making up their minds. they told the student that is was all my fault.
check and cycle your batteries, don't wait until the plane hits the ground to find out what shape your batteries are in. Dennis
