It would probably depend on the materials I was going to use for the tip. If I were making the tip from steel tube, like on the plans, I think I would extend...
Our DI has suffered from precession for some time and I wanted to check if there was sufficient suction. The venturis ( there is also one for the AH) are...
I would suggest finding an 85 hp airplane to go for a ride in. I originally thought that an O-200 W-10 was the top of the mountain, but now that I have an...
Bill, Thanks for the reply. I do understand What you mean about the lower spar cap. What do you think about notching and then putting a doubler on each side...
Bruce, I'm not an engineer so I would rather not comment. I think that some sort of reinforcement would be needed, such as a doubler, but to what extent, I...

Bill and Dave, Thanks for the info. I don't think there are any kinks in the tubes but th venturis are fairly small. It's an gpu O-290 and I'm not sure if ...
The venturi installed at the factory inside the cowl of a Bellanca 14-13-2 only drove a T&B. Not enough for any thing else. My Bellanca has two external...
Cy, I take your internal venturi has been removed and ones on the boot cowl are external. Do you have any info, drawings or photos of the internal one? I'm...
It was removed many years ago. Bracket spot welded on the Aluminum nose bowl is still there as is the feed hole for the venturi. From what I can tell it was...
