Thanks for the info, unfortunately, it means I have to find another spot for the A123's (four packs), and they looked so nice up along the nose.
The 4 packs are 2 for the Receiver, one for the ECU and one for lights..

Well now to see if they will fit under the front cockpit..

Thanks for the help.

Regards
Ross

ps The weight is 18.7kg empty but ready to go, ie 41lbs.
Is that too heavy or not a problem??

Regarding to CG : I tied a string to the wing-tube and balanced it on the wing-tube as a starting-point. (slight nose-down attitude)
I only needed a few grams of lead. IIRC I needed a few clicks of down, and Koen (who flew after my first flight) needed a bit of down inverted. So I think the CG could move a little further aft, but right on the wing-tube is a good starting-point.

Don't worry about the weight. Mine is a tad over 20kg dry, and it floats forever. I flew around half throttle most of the time. (P200) so I think you will be fine.
