I believe the original was designed for a Veco .35, not a Fox .35.

A suitable modern replacement could the .46LA, although it's a little heavier and more powerful than the original. Balance could be an issue.

Another could be an OS .35-S. They are good stunt engines, more power than a Fox, and less fiddly (no burp).

Another choice would be simply convert to electric. A BadAss 2820-910 on a 4-cell battery would be a pretty good combo.

Yeah, I fat-fingered it. It's supposed to be the 2820-910.

Thanks for this. I have a Brodak 40, an LA 40 and an LA 46. Spoiled for choice.

  George mentioned  RO Jett .40.   A super choice since it's in a .25 size case.   Pretty pricey if you don't have one.   I have pulled up to 64 ounce airplanes with it though.   My next choice would likely be the OS .35S- again weight and 'classic' type power.   Of what you mention you have I'd probably do the Brodak .40.   Never had one but I know they are light and I've seen them run well.   The other engines you mention can work but will be heavier, especially with a muffler.    Since these like to run mostly two stroking the muffler is almost a requirement.   The older engines breaking in and out seem far less annoying -to me anyways.   An old Merco .35 or Blackstreak .40 would also be a good choice.    I have an old Thunderbird kit here that might get the Merco Blackstreak in it .  It sounds like you understand these old Classic airplanes were designed around 6-7 ounce,  non-muffled engines and that's what you'll need to get the best performance from them.

The other thing to remember is in the classic era, we did one lap between maneuvers.. Now with two, that is at least 15 extra laps, so tank accordingly.. I didn't, ran under , missed the over head and 4 leaf.. ARRRGGHH.

I don't know exactly when the two lap rules started.   They had to be before 1965 because that's when I started flying stunt airplanes and it has always been two laps since I started.   I know it was one lap during most the early 50's,  hence the super short-nosed airplanes you can't get a large enough tank in now.   That was cruel and unusual punishment on judges.   Sometimes it's hard enough to get accomplished with two laps.

On a few of my classics I had to extend the nose 1 to 1/2 inches to accomodate the tank..Then about 1973 they added mufflers.. Balance became a trick. I know it was one lap in 64 when I started stunt. Did mostly combat and some carrier, got serious about stunt in 69, did my first full pattern in April 69 and I thought it was still one lap then.. 

  I have some old rule books from back then, so I'll check the next time I'm in the basement. I was under the impression that the one lap between tricks ended with the OTS era because George's new pattern had more tricks to it???

Ty it wouldn't surprise me if this was one of those things that evolved in the beginning depending on where the contest was and how the CD played it sort of like the BOM rules today.   It would be interesting if rule change dates were recorded at AMA someplace.   I'm sure it could be researched if you went back through old rule books in the library at the museum.  Maybe I'll make a reminder to myself and do that during the Nats this year when it rains or blows.

I wonder why they are not digitized and on their Web Site now.

Ken

Likely the costs involved and maybe nobody pushed it.   The amount of stuff in the library is really pretty amazing.

Dave

Actually the time required can be a lot.   I scanned and loaded the old issues of Stunt News for the PAMPA website.   That took almost a month of evenings and weekends.  Then we found it increased the website costs annually for the storage space from the web.   AMA would probably have to hire an outside company to do the work if they were to digitize the whole library and the cost might be more than they consider worthwhile.

  I have rule books for 1959/60, 1962, 1964 and 1965, and all of them mention one lap between maneuvers. Interesting to look at because the size of the rule book in pages and each section really increased from 1959 to 1965!!
