Norvel Tee Dee.049 Mount/tanks

Ken Cook wrote:In addition to the leaks the Norvel units are plagued with, the pickup isn't exactly in the correct position for sustained inverted flight. They also place the engine far too forward. If your current plane isn't adjusted for this it's incredibly nose heavy.

Interesting the two extended Norvel tanks have little "clunks" for inverted performance hard to see in the photos... but I wouldn't use them anyway..
If somebody's interested in these tanks... maybe we could arrange a trade? for say a Kirn-Kraft needle assy.?

I have not tried the extended Norvel tank, but the regular one was vibrating quite a bit on my little reed speed plane that I used in a contest here. I don't think the Norvel vibrates as much but the TD has a pretty heavy piston and it shakes with high revs. A bigger balanced prop would likely be fine. I really could not get a setting, as it was foaming up so much. It did fit the Bee bolt pattern though which was nice. I had to saw off the firewall and move it back for balance, and redo the fiberglass and repaint the nose to try that. Always wanted to see the speed difference between the Bees, TD and Norvels on the same plane and prop. You may find a taker for the KK needle trade against a postage stamp backplate here, but I doubt there are many guys with a remote KK needle valve to trade.

I was gifted a Norvel .049 C/L engine several years ago.. which has a similar tank. I haven't tried running the engine yet.. so I can't speak for the tanks' integrity.





The below photo is likely what Ken Cook was referring to.. regarding a "fixed" fuel-pickup tube within the tank. There's no "clunk" in this tank...  



then again.... this style tank surely had a "specific purpose"..

yeah the longer one has a back part and a tiny clunk.. pictured on left and the short one has just a rather poorly placed brass tube pickup...

I have a lot of Norvel accessories and engines. I never knew the clunk was available. I suppose they discovered the above mentioned problem with the fixed pipe version.
