Shaun Hi, OK if I was building another one (which i wont) I would have used my brain a bit more and tacked in the servos BEFORE I fitted E1 & E2. thus ensuring that all was in the correct place. It would hav been really usefull if those dimentions where in the manula on page 15. All it says is Trial fit E1 and trim as necessary. I did use the Fan housing to space things but I did have the fan installed. At this stage of the build you dont have the inlet ducts in place so you have no idea how little room there is. I respectfully suggest that the manula needs to be updated for simpletons like me.
However: the good news is that as I use a space age adhesive to fix all my formers into fiberglass (its a 2 pack adhesive used in the motor trade to fit kevlar and fiberglass body panels onto performance cars), I could have dug out the formers. But I chose a different route. By carefully "notching out" E1 I have managed to fit in the servos in such a way as to allow full movement, easy removal of the servo, clevis and servo arm and maintain the structural integrity and rigidity of the mount. Just to make sure we glassed in a few carbon strands. I will send pics as soon as I am able. Incidently, in case you worry, the brains behind the mod is also a UK CAA inspector for large 20 kg plus models so It should work. By the way having rigged up the pushrods I can see why you need a 6.5kg servo!!! Thanks again for your help. BigT
