Header tank or no

[Harya]

Hi all,

Do you prefer using header tank on your 600 N or without header tank and could you please give a reason

Regards,

2 Reasons #1 is to keep a full tank head on the main carb. feed when inverted or in low Main tank to keep from sucking air into the fuel feed (Hence causing a lean run ,even if only for a second)
#2 is that it give you the ability to run the main tank empty and still have say 1 min 1/2 to Land its a nice little buffer to give you a few moments of flight time.Not mention its reassuring :banana:cheers

I have laid it on the back as i have hoovered / easy flyed (pirouettes, 8's and such) 5 tanks, and engine didnt even fuzz until tank was empty :)

I prefer using one because I can get longer flight times out of it. Plus you don't have to worry about sucking air when the tank gets low.

I cant figure out how to mount mine. Anyone got any hints/pics/vids? ;)

I won't fly without one..... I saw a very expensive crash of a friends JR Vibe 90 all because it sucked air while he was half way through a roll, the vibe was nearly totaled....... Have a look at the photo's on my profile of whats left of it....... He couldn't be bothered to fix it so he gave it to me to keep :):):):)

Hi Harya,

I wasn't flying with one last week and the clunk went dry on a fast low pass. I was very lucky to get it down without damage. There was still fuel in the tank, but the clunk couldn't pick it up. That's when I decided it was worth it to put a header tank on.

I went with the Thunder Tiger tank because it has a grommet isolation mount and a plastic bracket that will break away in a crash. I just used one of the extra plastic standoffs with a hole all the way through it that came with my 600N. I cut it down to size with my Dremel tool.

I've got to run now, but I'll try to get some pics later.

Oh, and I'm running the O.S. Bubbleless clunk, but I don't think that's enough anymore.

Keep 'em flying.:YeaBaby:

Take out the rear screw on the bottom bearing block. Use a sawed off plastic canopy mount with one of the short threaded rods and stick it right in there. Saves drilling a hole in the frame. Someone has a picture of that done here somewhere. Do a search for header tank and you should find it pretty easy.

Hmm wont that be very loose?

I drilled a hole in the frame, and used one of the spare plastic hex sections cut down, with a self tapping screw in each end. Works a treat.

Not loose at all. The threaded portion in the plastic standoff will stay tight on its own. You thread lock the end into the bearing block just like you would the screw. Then screw your header tank to the stand off. You can drill a hole if you want, just get ready for the frame to crack there when a crash moves the header tank. Edit: here is the photo I mentioned earlier.

Thats my heli :thumbup:

I used a metal stand off that is a frame spacer from a HDX500, the thinking there was that the Header Tank bracket is plastic and it can dissipate the forces of a crash ie break. Iwanted to make sure the bottom bearing bracket mounting was not jeopardised.

Exact same setup here, except I used an aluminum hex section from a Rappy.

Thanks fot the answer guys, no doubt i have to put header tank on, it looks not really nice but gave me confident to fly my 600 like my old raptor

Hi All,

I tried out my header tank this weekend. It worked great. I was able to fly inverted right down to the last quarter inch in the main tank. That's something I was afraid to do before. I came in with a quarter inch left in the main tank, and the header tank was still completely full. Nice system. Good insurance.

I was worried about the tank rotating. It did rotate clockwise a couple of degrees and held there. It's not enough to worry about. If it rotates more, I'm going to shorten my standoff and use foam tape to secure it to the main tank.

Keep 'em flying.:YeaBaby:
