Title: Little Fox passes flight test
Post by: Leo Mehl on April 15, 2008, 01:52:59 PM
Well I guess all the wing warps equalled out so the plane prettymuch flew good from the start. I would like to think I am a good builder and I know I am not but I did full pattern on second flight. Only thing I had to do was take off some tail wieght. Now IO need longer lines. Fox 25 breaks like Fox 35 but need to load the engine with bigger prop. Like I say this is a ballpark fun flyer. #^ #^ #^ #^ #^ HH%% HH%% HH%% HH%% HH%% HB~>

No Fair!  It's going to still be a couple months before i can go flying anytime I want to! LL~ LL~

Great news, Brother Leo!

Is it a 4 bolt backplate Fox 25 w/screw on venturi?

Nope> It's the 3 bolt backplat with the long cast venturi. Scott Riese made the exhuast extension for it. The engine runs great. I just need more load on it for a little better break and I think I could actually run a muffler on it. Fun stuff. Plane built off Artic Fox plans that Pat Johnston drew. I just had them reduced to 38" wingspan.

What prop were you running on it Leo?  I have the ' AP^54 Model Fox 25 and was thinking of using it on a light ringmaster.  I was thinking a
9/6.

I was using a 9-5 but think I can use a 10-6 or 10-5

Hi Leo,

I have several of those model Fox 25s (1054-1957).  They seem to have all the positives of the stunt run of a good Fox 35 (and about as strong!) but weigh so much less (.29 sleeve/piston in a .19 case!).  They will fly a Still Stuka REAL good as long as it isn't a really over weight pig.

I got some 9.5-6 Aldrich props (Prather gauge=5, 5 1/2 pitch), and they work really great in most set ups.  A 10-5 might be pushing it, unless it is a nice lightweight wood.  Maybe not.........

The plane flys good and stays in the grove both directions but it still needs trim. To make it fly like a larger plane you have to take away the jumpyness that small lite planes are accustomed to doing or as we say it's a little squarrely. This is what I will be doing the next time out. I like small planes but they really require more trimming to make them fly a really good pattern. It's just fun and maybe a waste of time but it shure fits in the car good. HB~>
