Posted by Simon Day on 21/07/2010 14:10:17: Having read this thread with great interest I've re-fitted my spitfire,I used to fly it unsuccessfully on old brushed motor and horrible heavy batteries, so thought I'd re-work it with the new stuff I have in other models... However... I'm no-where near the weight, (983g or 2lb 2.7oz) and can't balance on a CofG 75mm back from the leading edge... have to add 100g up front...?? From everything I've read here lighter is better, but it's got to balance... my set up is very similar to those here - out-runner, 35amp SC, 2500 LiPo, so if anything quite heavy up front... Has anyone any tips on lightening the tail (so saving the extra 100g in the nose)? I can't see how I can be so far out everyone else... Or should I just add the weight?Fit something like a 3000mah 3s1p or, as on ours, a 4500mah 3s1p and she'll balance just fine. better to carry another 2000mah of capacity than 100g of dead weight.
