The former can't go far enough back to only have 10mm of the thrust tube prtruding it. Stve built Ali's with the tube 5mm back from being level with the back of the fuz.
yea i think it's an optical illusion mate. It looks centred but it's actually pointing towards the bottom of the thrust tube.
then check the nottom of the pipe that must be really Blue and a big difference with the top of the pipe..dangerous!
you can also use a piece of strait balsa and put it on top of the Bearer and mount it backwards , now you should see the true position
if they are in 1 line all is ok , even if the complete thrustline pointing downwards.
