Here you go. That will cost you one OS.25FP tho ")

I suggest that you use a longer bolt and another piece of ply at the top over the bolt.

^^^^^^^^^^^^^
+1, that is some good advice. I like to do that on the ARF models as well, since I normally take the bell crank out and bush the lead outs anyway.

Looks good, but I still prefer top and bottom support on the bolt, just because the pull test puts a twisting force on the platform without the top support.
That being said, it will no likely last 100 years!
I hope you get to test that.

I'm not sure this is what your looking for but it is Shark related.  This is the bellcrank mount system as shown on the plans for the Jetco Shark 45.  Free plan down load available at Hippocket.  The crank is suspended between two plywood panels.





 

I just want to say thanks to all of you for your advice and to my brother who did most of the work.

This picture is before the crash.

And now.  The lastest version of this Shark 402 and my brother master repairer, Ron.

Thanks,  good finishes are my brother's work.

Does anyone know if it works alright to keep the Hayes tank mounted with the foot against the fuselage?  I usually put it down.  I will have to cut the mounting straps and start over with the tank mount, it that's necessary.  All that lacks is tightening the tank.  Then, it's ready to fly.

How have you got it vented?   As long as the pick up is in the fuel while flying and the vents are in the right place, it should work as you have it mounted.    Now, what caused the crash?

James, that sounds like a more secure way of installing them.  I saw a picture of them like that in another post.

Also, Doc.  As the tank is mounted with the bulge or foot down.  The pickup is the lowest one.  I use the middle one as the fill and then cap it off. The top one I leave uncapped.  I am not using pressure.  The motor is an OS 25 pre FP.  Seems to run fine.
