The third photo looks like the normal setup to me. The crimped edge fastened to the front side of the firewall is as I remember the way Piper built them. Your boot cowl that extends forward of the firewall doesn't look original to me. Any reason why you couldn't just trim it back even with the firewall? Are there any Cubs in your area that you could take a look at? Should make it easier to decide what to do if you see an original cowling installation.
Good Luck, Bill

rooster created a new topic ' The new engine mount does not fit our cub' in the forum. 2 weeks ago

I've got a J-3 Cub and am replacing the engine mount. After taking the old engine mount off I noticed that all 4 of the motor mount / boot cowling brackets have been either cut and welded at an angle or just bent so the mount will fit against the fire wall... and at the same time clear the 'lip' in the fire wall / skin to avoid rubbing where the riveted exterior skin and fire wall are joined.

The boot cowl brackets are straight and do not clear the area where the riveted exterior skin and fire wall are joined.

Seems like there are three options:
1. Cut the skin back to allow for the straight brackets to align as sent from the factory.
2. Have the engine mount brackets cut and welded (or bend?) to allow for the skin/fire wall joint.
3. Find another manufacture of engine mounts that account for this situation.
Two photos show my engine mount... the other is a cub that has the mount wall an exterior skin lapped over into the firewall... which would accommodate

the new mount.
What do you think?

We have been using one HD and one standard with good results. Depending on your cereal number it would be a 1280 and a 1280HD for each side. We have a shock cord tool you can borrow for the cost of shipping each way.

It is time to replace the bungees on my 1945 J3 C-65. I’ve noticed they come in different sizes and strength. My Cub is based at a paved runway if that makes a difference. Any recommendations?

Thank you Donald. I am familiar with that stuff but wish I had the drawing for the left hand forward jury strut or the pitot installation. I suspect that one of those drawings likely has a specific alignment defined.

Hello,
I just got my cub back from annual and I noticed that the pitot appears to be at a considerably different angle from the oncoming wind at level flight attitude. Perhaps this is normal but I think I recall it was relatively aligned with the slipstream in level flight. I have searched online and though the cub assembly and rigging manuals and have found nothing at all that defines this angle. I also noticed that the indicated airspeed is low by about 7 mph based on 2 way GPS as compared to before.
Does anyone have any authoritative information that sets its angle relative to either the under surface of the wing at the jury strut station or to the jury strut leading edge?
Thanks![/quote

Good question. Never thought about it. It seems the pitot tube should be aligned parallel with the bottom of the wing. That's the airspeed that generates the low pressure area on top of the wing which generates the lift. Check out www.youtube.com/watch?v=iZWtCW4sXc0 which I haven't studied prior to this post.

beaverbill1@hotmail.com replied to the topic 'ADS-B' in the forum. 1 month ago

FAR 91.225 (e) should help sort it out. As you said, an aircraft originally certificated without an electrical system, and which has not had an engine driven electrical power source added gets an exemption. Full disclosure, I do not hsve any legal training so take my comments on the FAR's with the usual healthy dose of scepticism!
Hope this helps, Bill

Sorry if this is already on the forum somewhere - for the life of me - I can't figure out how to search the forum....
Can someone point me to an explanation of the ADS-B requirements and how it relates to airplanes certificated without an electrical system? Say - like a cub :)

thanks

Cub Dr. has the original stitching diagram and uses less stitching than the FAA manual requires.

My set of Cub Clues may be the only complete set in existence. I don't have the technical savvy to produce them electronically for the website to have so they can be downloaded. But I'm willing to make them available for someone interested in taking up this task. By making them available I don't mean I'm willing to send them off for this purpose. They are not leaving my possession in Bedford Indiana.. My phone is 812 275-5269. Thanks.

kschmitt replied to the topic 'The new (to me) 42" flexible antennas.' in the forum. 3 months ago

Thanks for the feedback. I have found that with the flat fore and aft i got a poor signal front and back but good to the sides when aimed at the station. Have now mounted it with the edge fore and aft but have not had the time to test it much yet. A quick flight showed better fore and and aft reception but fairly weak with some noise. Will know more after a couple more tests.

Put one in mine behind the baggage compartment. Works well, a little weak on the nose but mostly when using an AWOS station which have weak transmit signals anyway. Great antenna, sure beats having an ugly external antenna.

Thanks for the reply. I'm still expermenting with it. With the flat side fore and aft it only picks up when facing 90 degrees to either side. I am trying it turned so it should transmit and receive heading to or from a station. if this doesn't work well enough will put in a ground plate and go to a conventional whip antenna. Time will tell.

beaverbill1@hotmail.com replied to the topic 'The new (to me) 42" flexible antennas.' in the forum. 3 months ago

I had read various comments on the pros and cons of these antennas. So I tried one in the aft fuselage of a Taylorcraft BC12D. Installed in accordance with the manufacturers instructions. It worked, but not as well as I had hoped. I replaced it with a conventional antenna in the same location in the fuselage, with a ground plane. This works, but I still suspect an external antenna would function better. The aircraft structure seems to affect the radio signal. For instance, flying directly toward the station decreases reception compared to flying at right angles to the station. These are just my observations so far. And I readily admit to a very limited understanding of anything electronic. It's all pretty much magic to me.
