Its not bad is it !
As I said in my previous post - this model is just great at landings - it has so far made all my attempts look absolutely perfect
I measured my CoG this morning - its 140mm, so I guess you can safely bring it back quite a bit.
I made a tray that fits behind the canopy (you need to cut the film covering) and fitted my Multiplex IPX RX back there. I'm using a 3amp Medusa super BEC to power the radio. Single elevator servo down at the back end (cheap futaba digitals all round) - elevator halves joined by a carbon rod.
I'm saving up for some lipo batteries - I can save at least a lb of weight by ditching the 16 cell nimh packs - so the lower voltage of a 4s pack should be offset by the lighter weight!
Anyway - have fun with your Harrier ... I know I am!
