Not to the engine, per se. NORVEL contends that minute amounts of dissolved rubber would be deposited on the glow element, causing poor performance. The ignition process in glow engines is started with an external power source to heat the element, but the element remains hot in part due to a catalytic reaction between platinum in the element and methyl alcohol vapor. If the element becomes coated, it can reduce the amount of surface area of the element that comes into contact with the methyl alcohol and reduce generated element heat.

Is this true?? I don't know -- I had used a Sullivan fuel bulb for years without problems or so I thought. Perhaps the Sullivan rubber was not as prone to breaking down.

However, I now use an all nylon syringe for fueling -- just to be safe (bought it from NORVEL -- maybe I'm another victim of marketing strategy). Even with a nylon syringe, I have noticed some of my NORVEL plug elements seem to grow a gray fur!!!

Status: offline 		All,

I just nose-dived my AT-6 into the ground and the carb broke off at the body of the engine (Norvell .061 R/C). Is there a way to repair it? Can I weld or glue it back together or is it better to order a new carb? The engine was running great and I want to keep it running that way. (I know that running it into the ground is not a good way to prolong it's life.)

Best bet is a new carby or carb body, failing being able to locate one I only know of 2 options to repair yours.
First the carb must be dismanted and thougholy cleaned - boil it it dish detergent and water, then thougoly wash with alcahol. then------
1/ Braze it together useing the low temp aluminium(zinc) rods useing LPG torch or
2/ glue it together useing the original slow set "Araldite"
maybe superglue will work too, not sure how it stands being in contact with nitro fuels

Clean it. JB Weld it. Cheap, simple!

Yep! Just make sure all mating parts are absolutely oil free -- a good cleaning with acetone will work well.

You might find a replacement on-line, but parts are pretty scarce now. Since SIG dropped their dealer network pricing, buying directly through them is very expensive.

Status: offline 		this is a question possibly a little off topic, but i was wondering just how much noise these little engines make (norvel big mig .061)
the reason im asking, is the club i fly at only has one undisturbed night to fly per week, b/c of the dirtbike track right beside it. there is a nice open field about the size of a soccer field and was wondering if a .061 would make too much noise and irritate anyone living in that area?
an audio clip or video would help alot.
thanx,

Status: offline 		I have an AME .061 that'll go in something someday...hopefully soon (well...it might just be a 1/2A Pathfinder). Never having done so just how does one run a pressure tap off the muffler? Never flown an external tank before. I noticed the tap on the muffler was much larger than the line they give you with the engine. What am I missing?

Thanks,

Rob

Status: offline 		Pressure line goes to a brass tube that sits inside at Top of tank. Fuel Feed is on a Clunk/weight on the bottom of tank and runs to Carb..use the fuel feed line,that goes to carb to fill the Tank..Pretty simple..Ideal tank location is , Center of tank, at the height of carb fuel inlet.

Andrew,

Unlike 1/2As of the past, the newer offerings do give you a muffler that is fairly effective. Still 1/2As run at relatively high RPMs, 18K as opposed to 8K for a .40, for instance and it's not the decibels that the neighbours find annoying, it's the pitch. We are designed, by the miracle of evolution, to respond to higher frequencies in the environment. As in the higher pitched wail of a baby gets a mother's attention real quick. Or the higher pitched meow of baby kittens or yip of puppies etc.

You can get them real quiet but this takes a lathe and some FlyQuiet tubing. I typically install a bolt on header to my Norvels and install FlyQuiet tubing as per the Low Stik below. What you get is a muffler with huge volume, which helps but what really does the trick is to install a baffle inside the tubing portion, about halfway. This really helps.

The best set up is much longer tubing with the baffle adjusted to create a tuned pipe effect. You get a boost of power about 500 RPM and a very quiet airplane. Cumbersome but it works well on my Tsunami.

Orrr, you could just fly at the site in question and see what happens. I fly my now Brodak powered Low Stik at the local park and so far, despite the conventional muffler, no one has complained and the park is quite a busy place.


Well, RCU won't let me download any pics right now. I'll sign off and maybe try again tomorrow.

Do norvels absolutely need pressure or is it just an added bonus?
