National Aeronca Association Bulletin Board

One side heavier due to not being level from side to side. I reweighed and leveled from side to side, only 20 lbs. diff then. My GW is 1320 lbs. based on STC I purchased, UL is 371. I am confused about that 70 lbs. (actually 67.6) because in the calc. I included every little thing/item like seat cus...

Anyone aware of an approval for a Cub style door mod for a Champ?

Here is what I found after listening to the many good comments; ------------------------ method-------------------------------------------------------EW-------RH main------LH main----tail---------EWCG 2 bath room scales moving location, leveling plane in 2 axis June 21---------970.8-------464-------...

Thanks for the comments. I guess I believed that old EW of 940 too much and was thinking how I was reducing it by taking out the generator, radio, electric compass and so on. Was disappointing to see that it gained 30 pounds after all that removal and conversion to lightweight starter and battery. O...

I looked at a 337 from 1956 for the Champ I am working on. 1956 was the last time that it was actually weighed, until now. In 1956 gravity must have been different from now because every scale number ends in zero, example 440, 70, 430, 50.... At that time the EW also ended in zero, 940 lbs. In 1956 ...

I am not familiar with this subject.

What discs?

What dues? Where to send?

Mike,

I can make you a picture of mine but will have to send it to you by email.

I have your email address. If you don't get it in a few days email me.

Dave

Bob, I would say that $500 would be on the high side. There are no standard cranks around and the .010 unders are getting old too. With unknown conditions you might end up with nothing. Paul I have a standard crank that is certified and yellow tagged. The certification and tag were done about 2-3 y...

Hi Bob, I tried to attach it but it says .pdf is not permitted, send me and email and I will send you the file. It is the Aeronca helps and hints #14 from 1961. I like most the use of an 18" bar and no bigger, it avoids over torque. I realize that I do not follow it exactly, my bad. I put a lot...

The Cub club method and those like it use a higher torque than one will achieve with the Aeronca method.

That makes me curious about the incidence of cracked hubs using the high torque method. I wonder if there is a higher incidence of cracked keyways using the high torque method.

Dave

Hi Gus, I have had a similar issue like yours with the hub. I usually remove the the prop then unscrew the hub nut to a point where it was tight and I could not turn it any more due to strength limits and fear of doing damage. I do not use a 4' pipe but rather an 18" extension from my 3/8"...

Thanks for the advice and insights guys.

Does anyone know the story behind this item on the TCDS ? It seems clear regarding the 7EC but how does this apply to a 7CCM or 7DC? 109.
