That terrifying sound before the silence. Migrating my F27 guts to a new fuselage.

It took hundreds of flights and 4 months, but I critted out. With a brief lapse in situational awareness, I corkscrewed my stryker into the ground. Knowing the law of entropy, I picked up a replacement fuselage a few weeks ago.

Are there any tips I should know about building out the new fuselage? I'm interested in setting the powerplant angle of attack. Is there a limit to how much torque to put on the screws so not to damage the foam or affect the angle of attack for the prop? Are there any critical tolerances or settings to remember?

Anyone knowing and understanding entropy should have no problem with mundane
subjects such as mounting an engine. :>)

CTD,
Thanks, great info.

In that post, Glacier Girl stated:
Before you fly check the side to side and front to back angles on your motor. From the rear, motor should be dead straight in line with the fuselage center line. If it isn't your bird will want to keep turning in one direction. Front to back alignment is critical to proper flight. Remove one tail fin, take a straight edge(a yard stick works well), line it up with the motor shaft back to front, if you follow that line it should exit at the center of the nose cone,from the side view. Off angles on this will cause the bird to want to climb badly on acceleration,the rear of the mount is too high vs the front. Or it will dive if the opposite exists. Your bird should fly level no matter what the throttle setting is.
This is the kind info I'm looking for. Other planes I have require an offset relation to the prop rotation. I wasn't sure this craft was the same. GG seems to have a wealth of knowledge and experience with the f27.

Who said "NOSE CONE"???? Nose cones go on rockets....spinners go
onpropellors.... nose cone? Yechhhhhh....unless of course, it is a
pusher with a rounded nose...then I suppose you could call it a nose
cone...but I still think it is incorrect.

Incorrect or not, it's a popular term. Especially with the glider
guys, where there's often literally a nose that fits over the nose of
the plane. (Instead of a canopy or something similar.)

Woohoo! Where's the party?

Frank,
I understood perfectly, but probably from my old occupation. Search the web for LGM30F and you'll understand.

Doug,
Thanks for having my back.
