Wooooow.. Beautiful bird Bob!!! It seems Align did it again!! Can't wait to see how it flies!

Hi, Bob. You must have the greatest job ever....or is it a task? Anyway great work.

I suppose the flat spots on the clutch hub is for holding it with a big wrench while thightening and loosening the nut to the crankshaft, instead of the cloth....

i have a question..... does it matter where the fuel clunk goes? i noticed that you have it on the inside of the frames, but from another vid it's on the outside of the frames. is this just a preference or does the manual show it on the inside.:confused:


just wondering

[Finless]

???? I have no vid that shows the clunk line on the outside of the frames? I am totally unclear what your talking about? MAKE SURE your not looking at the tank plug on the outside of the frame! That is a tank plug rubber NOT the fuel pickup system!

I sent Bob a tip about fuel lines in the tank, and he asked me to post it here. This tip was given to me by my buddy Russ McCutcheon of Vancouver Wash. If you look at fuel line it has a natural roll to it. This is because it has be rolled around a spool, and it wants to stay in that shape. The trick is install the fuel line so the natural roll points to the top of the tank. The fuel line will move easier in the direction of the natural roll. When flying upright gravity will pull the clunk down into the fuel. The natural roll to the fuel line will help the line move to the top of the tank when inverted. It makes a big difference when doing long inverted manuvers.
Try it, you will see how easy the line falls to the top of the tank, and the corners where the fuel is hidding.
Bob asked about after the line sits in fuel, will it still want to hold the rolled shape. The answer is yes. I have pulled out old line, set it on the table and it still held the the shape. It is going to be softer, but it still has some rolled shape to it.
Like I told Bob. I usally have to fish it out of the tank after it falls apart anyway.

Thanks Kevin! I will check this out next time I have a chance but it sounds like totally sound advise! Thanks for sharing it...... :noteworthy

the fuel pick up system that goes from the tank to the inlet of the carb not inside the tank

maybe im seeing things :dontknow but here is the vid i think i saw it in :thumbup:

[toaster12]

It was moved to the centre of the tank because it didn't reach all corners of the tank when mounted at the side.

The last thing you want is poor fuel delivery! So it has to be mounted in the middle.

ok, i was just wondering

Great work Bob,
That rubber gromit/nipple on my Raptor was alot easier to put on the tank than on my T-rex 600N, now having to do that between the motor and tank it's not going to be fun.

It would be nice that the production would be different, maybe a 45 degrees shape on the tank, like on the Aurora, or if it would work on a 45 degrees on the front bottom part of the tank, but that would be more work, the frame would have to be designed for that.

I think that it will be hard to put the rubber/nipple when it has to be done at the field.

I think it's much easier to first mount the grommet, then the nipple, that just needs to be pushed in to a stop, instead of getting it correct all the way round. (bad english, sorry)

[Finless]

It was not a big deal pushing in the fuel nipple and grommet... At first I thought it would be a problem but as you see in the video it went right in.

Bob

What about removing it if you have to remove the tank? I would think you'd damage it..?

[Finless]

Well thats true... I pulled mine out by the nipple and it took some force... I was worried I would break it but it was fine. So yea it will be tough to get out but doable.

Might be easier to remove the rubber bumper ring on one side of the frame and then you might be able to get the tank out without removing the nipple... I haven't tried that idea but it might work.

Well, that's what these pre-production kits are for, right? Align should see this and do a re-design as "nelson j" suggested. Move the nipple to the outside of the frame, re-shape the tank similar to the far superior Aurora :lol:. Kidding!

But seriously, that's what these kits are suppose to be for.....

[huskynox]

Ya know, all the original prototype pictures show the fuel nipple on the outside of the frame.

Are you sure the manual isn't bass ackwards...
