Finally repaired my plane and got two 3S 20C 2200mAh batteries.
Can I connect two batteries in parallel for increasing my capacity.Also there is a necessity to place two batteries to maintain the CG of the plane at 1/3rd the chord length from leading edge.

Yeah you can use two batteries in parallel but make sure they are at the same voltage before connecting! Smiley

Looks fine but aren't you pushing the plane to limits !!!

firstly 2200mah battery is way too heavy then 2 of them...... Huge payload on plane.

I would suggest a lighter & power efficient plane .....

You are right rastsaurabh , but without two batteries the C.G. too far behind.The AUW is 1.6Kg and the motor is 500W and wingspan 54"

I would always suggest to rectify the issue..... i remember making a tail with 2 coro sheets .. it was too good and nice but did not use as it was heavy and i  would have landed in situation like yours.

adding a battery is a wise action than adding dead weight though. see if you can reduce the tail a  bit....

such a heavy plane with single coro layer may get exposed to all types of pressures during flight and result in free fall !!!
IF no choice then go for it atleast have a easy & endless flight ..... you can keep flying for >30 min!!!!! with those 2 power houses on your plane.... double check for any screws in your battery compartment this time.

Fly High
Santhosh I second to rastsaurabh.. That making more load will result in loss of control and free fall when the throttle is reduced under limit while flying.. Is moving the wings possible to change cg?  Sad
Any way wait for some advices from  experts.. Smiley

Arun ,it is not possible to move the wings...Sad and also the tail ...  Huh?
I have turned the screws inside out so that the heads of the screws are inside the compartment.And also I place a foam piece to protect the batteries from  the screws..

Flew my plane with Krishnamoorthy (RC maker).. on 17 FEB 2013.
Krishna set up all the settings required..my plane had a lot of lift so a counter down elevator was required for a stable flight.
I flew for about nearly 15mins...on a single charge....when I was about to hand the Tx to krishna for landing there was a abrupt change in direction of wind and forced my plane down to the ground....The plane broke into three pieces..lost one battery - the 2nd cell showed 0.24V  and overall 7.5V for a 3S..The other one survived..

Myself with Krishnamoorthy(holding the Radio)

good atleast you have 15 min of flying..... ( did you practice on Simulator?).....
but loosing 2 batteries on 2 sorties is a bad part.... next time plan a lighter plane and it should last long!!!!

for me its different i dont know flying and loose models due to crash.... but others fly them gracefully.!!!
