OK, so SS and LS are pretty self-explanatory.

I have a grand total of ONE Nelson Q40 engines, acquired in various trades. I was thinking about dabbling in Q40 just a bit. I know it's a SS, the original owner had it before the LS ever hit the scene.

However, in an online auction the other day, I saw this heading:
NELSON Q-40 SS with latest good case

How does one without a background in the Q40 Nelsons know what era case one has? (I've had SS Nelson Q500's and even before that, Nelson .15's (QM)- but not enough of them to know how one knows which is the "latest good case"...)

Just curious, that's all.

One with a good case? well that is kinda subjective, basically they are saying is that it could be upgraded to an LS if you so wanted to.

Cases can get "tweaked" in crashes and be off a little. You notice its starting to lose a little so you put in a new top end, and its no better. A tweaked case will never run right, well, it won't be competitive anyway.

I do know that there have been a couple of different "neck" lengths - by that I mean where the venturi goes. I've seen two separate length venturis, think my case is the shorter of the two types.

Fizz,

Dont worry about it, I have one of the very first Q40 nelsons and with a 7.5 prop it really hauls a

D.E.

I'm not worried, just wondering what I have. I will probably find out in the spring how this one runs.. it was 12 degrees out this morning here, ain't no way I'm going to fly out in THAT sort of weather...

I'm getting too old for that.

G, I just got back from flying with Mike. So too old for the cold isn't gonna cut it!
We are thinking about a New Years Day 424 race! Are you guys in?

we have our club "freeze fly" on new years day, not sure how many of the Barnstormers you'd get for a race. Brrrr... it was 12 here this morning..

I bet I could find some FOOLS to come

Duane, I don't think it could be any colder than that race in K/C !!!![X(]

Thats true
