Hi Jack

Thanks................I did initially put the airframe together and added the equipment to get a rough idea where things needed to be. My equipment layout is different to yours too, my UAT will be much closer to the CG as will the pump and a few other things. Ive glued three of the box's in as close to F1 as possible but left the 2500 NiMh out for fine tuning. Ali does like his models with a forward CG hopefully it will work out, if not you're very welcome to say "I told you so"

Cheers, Alex
