RE: Falconwings Gear Door Tutorial
 

Good work and very educational. Wish I had your computer skills.

Dave, Thank you Thank you. Very good and will also print the Cyl work up, when you do it!!! Hooker53

Also need to make sure your pivot point on your hinges is in line, especially if you use more than one hinge. Otherwise good illustration of door hinging.

I figure since there are so many F-16s out there, most being ARF with crappy gear door work......you may find this aid relevant.

Cheers,
David

VERY well done..Concise and step by step. Thanks sooo much !
PS You should write manuals for the ARF companies....

Hey David, what about the gear door cylinder installation addendum.......There has been enough time to rest.......ha ha ha

I see you did this five years ago. Man I wish I would have seen it earlier! So nice to see someone sharing their building knowledge instead of the advertising a new product or bashing one….

Dave, really nice tutorial. I have been using that concept since i dont know how long and it works every time! Just my $.02- Could you do a tutorial for other things in landing gear install, like outer doors that must attach to the cylinder? I know there is a lot of trial and error figuring out the geometry, but just thought it may be easier to do on CAD...Thanks for the great work, you dont see "tutorials" or building advice much on here anymore probably because of the heavy influence of ARFs in the hobby now.

Wow- just realized this was from 5 years ago....My bad ;-)

No one's ever approached me, but yes I'd gladly do it. When I used to make installation drawings for F-35 Propulsion Stuff, mechanics would always compliment on how easy to read they were. If they can do it.....you can!! :-)

Guillo, Im on it :-)

NIck if you give me an example I could probably sketch something up.

FalconWings, Thank you for your sharing! Very useful and the CAD complements the instructions for clear understanding.

OK

Great old thread, I do the same thing but as the ghost of David Reid said, make sure the hinges line up. I usually pull the screws out of the hinges and drill them out for a wire hinge pin that runs through all of the hinges, and use it when gluing the bases down. As Falconwings says getting that hinge as close to the fuse as possible helps, great tip.

Ok, here we go, Door Cylinder installation.

#1 install the air cylinder to the door. The location of the sylinder mount on the door may take some trial and error, as it will define the amount of available "throw" for the door....similar to installing a control horn. On an F-16, it will have to be on the lower 20% of the door, mostly to keep it away from the wheel in the retracted position.
Retract the cylinder, and tape the door shut to the fuselage.http://www.rcuniverse.com/forum/atta...mentid=2115913

#2, swing the cylinder around along the door mount axis, and mark the circle traced on the bulkhead were the cylinder will be mounted.

#3, Now try locking the door in the open position, and make sure it clears the landing gear strut in the exended position.

#4, Swing the air cylinder along the gear door mount axis again in the extended position, and trace on the bulkhead where the cylinder will be mounted. The intersection of the two traced cylinders will mark the location of the air cylinder mount on the bulkhead.

#5 Finish the air cylinder installation. You may need to add 1/8" hardwoowd as a mounting block/standoff. It takes some trial and error to get it right, but this is the mechanical concept.

Perfect. Very nice job

Thank you David

Thanks so much for this.....
