Fuel Tank

[Trigger Fish]

Just started with R C Heli's. Question: How do you connect the fuel system? (Raptor 30 with OS .37 /heather gas tank? Thanks

One line from the vertical nipple on the main tank to the muffler nipple for fuel pressurization. Then from the main tank, you've got the clunk, clunk line, 90 degree elbow through the grommet in the tank, then to the header tank nipple. Then in the header tank, you've got the clunk, clunk line, straight nipple through the grommet in the header, then either to the engine, OR filter, then to the engine.

Had 2 successful flights this past Sunday (I was actually watching) our field expert performed a "safe for Flight inspection" and 2 flights. Question: How do you install the training gear, does it matter to which skid I connect it to? Heli: Raptor 30

Well, it depends on what kind of training gear you have. If it's just a couple of crossed rods, then it should be at a 45 each way and attach it to the front and back of each skid. If it's a rotopod, it should have clamps that attach to each skid. Just get it well-balanced and you'll be good to go.

Is a heather tank really necesary? It will just give extra fuel, or it does have a performance advantage?

There's a SMALL percentage of people out there who don't use a header tank, VERY SMALL. IMO yes, the header tank is necessary to keep the fuel flow into the engine consistant. What it does is keeps air bubles out of the fuel line to the engine. Heli's are rather finicky when they develop fuel delivery problems. It also does give you that extra 2oz. peace of mind in case you do run the main tank empty.

As a side note: make sure you replace the main tank's clunk line after 3-4 gallons or so. The glow fuel and exhaust tends to make the clunk line deteriorate over time. It's just a good safety measure. I've had one break on me. Luckily, I was able to auto it in.

The one I have has 4 rods that attach to a white plastic round pice. Note: Thanks for the tip concerning the clunk fuel line replacemement.

A lot of people are going to neoprene clunk lines now in the tanks. I have some on order right now. They hold up a lot better.
4 stout rubber bands will work well with that type of gear. Hook it around the tip of the skid, then wrap it around the gear & skid until it's tight, then hook it on the skid again.

A rotopod is what I used for training. Here is a picture to show what it looks like in case you don't know. They just clamp onto the skids really nice and provide a nice amount of cusion if you panic and slam it down. They are a little pricey cnsidering you'll probably never use it once you learn, you could always eBay it. I borrowed this one.

Great, got it. Note: Rotopod is the type that I have. By the way, Excellent paint job on the Heli.

[tdswan]

Thanks, but that paint job is long gone. It's sporting a tiger-striped theme this year. Don't know what it'll be next year.
