Flite Streak engine choice?

Quick and simple, it's only one or the other?

Johnson 35 or Fox 35.

I would regard them as interchangeable. And totally unsuited when we have readily available engines which are not only cheap but do a superior job of actually flying something like a Flite Streak.

A simple search here or on SSW will net you reams of material.

I have an ST G-23 on mine. With a 1/8 id venturi and 9 x 4 prop, it is slow enough to do a stunt pattern on 60 ft lines.

If its an ARF Flite Streak the nose might be too weak for a Fox, or anything but electric. There is some info by Dirty Dan on the whole Flite Streak ARF thing with a 20FP. There is also a video of an ARF Streak on youtube flying a very nice pattern with a 20FP. If its not an ARF just make sure the nose doesn't shake or you will never get an engine run. Also beware of the notorious Fox "burp". Really annoying. Never owned a Johnson. Lots of info out there whatever your choice is.

Thanks guys,

And I thought this was going to be real easy.

No, not ARF, I'm actually building a vintage kit.

Slight warps in the LE and TE, but nothing to drastic.

I have my old engines, and really didn't want to spend money for something new, but it looks like I have no choice if I want a good flying model.

Doing the pattern with it sounds interesting.

I still have a bit of building to do.

Thanks,

Hi Charles,

A Flite Streak with an OS .20FP has been used countless times to score over 500 points flying the AMA modern pattern out near Washington state.

I have the rebuild almost completed for Aaron's first "big" plane. It will get an OS .20FP BBTU.

Bill,

I looked around and found that .25 stunt Thread.

In that Thread, you mention changing the back plate and the NVA.

I would have to do this. Correct?

CB

Geoff Goodworth · « **Reply #10 on:** January 03, 2012, 07:17:50 PM »

Charles, I will assume an LA 25. The Thunder Tiger GP 25 backplate and gasket set fit and are available from Tower. If it is a rear needle version, best you fit the OS NVA, through the venturi, again available from Tower and listed as for the FP 20–40. It works for the LA 46 as well.

The plastic backplate can leak. One noted tuner has said the plastic backplate has leaked or will leak. I was surprised at how low the backplate screws were not tightened particularly tightly—just enough to ensure the backplate seals. Certainly not as tight as 'we' would tighten the screws with an aluminium backplate.

I would also replace the JIS cross-head screws with socket-head cap screws from Micro Fasteners while I was at it

Joseph Lijoi · « **Reply #11 on:** January 03, 2012, 07:50:07 PM »

Charles there are a ton of FP 25s and a few less FP 20s on Ebay and at swap meets. Many of them are new in box for about 50 bucks (or less). The venturi and needle valve mentioned fit the FP as well. No plastic backplate on the FP. The aeromaniacs site has info on the 20 FP Flite Sreak (ARF) set up by Dirty Dan. He hooks up the controls to the innermost bellcrank hole and has some suggestions for the CG. Dan recommends the later ABN version of the FP. How you can tell this on an Ebay picture is the port opposite the exhaust is more noticeable on the steel piston version. The ABN version almost looks like a baffle ported engine. Have fun!

Alan Hahn has an ARF Flite Streak powered by a FOX .15 schnuerle. It's not a combat setup, but it can do the entire pattern quite nicely.

Hi Charles,

I find the engines we are talking about are much more consistent and user friendly when thee back plate is replaced with a metal one and the NVA is of "normal" configuration. All thepoarts needed are available.

Plenty will say that the plastic back plate is fine. Personally I have never seen one that didn't eventually leak. I do not have time to fiddle with leaking back plates and such.

Yep, three tanks. Or as I told PW when he asked why the model had been so fitted, "Because I can't buy 1/2-ounce clunk tanks. Otherwise it would have six tanks."

This was merely an experiment. At the time I was considering--and in fact did so--installing a 6-ounce Hayes tank in my then-new Impact. The large tank fed a 1-ounce Sullivan round tank which then fed the RO-Jett 61.

Wouldn't the purchase of a bearing engine be a better choice?

John Miller · « **Reply #28 on:** January 05, 2012, 03:09:54 PM »

Charles, much of the decision, for engine choices, are based upon several different factors, common in CL stunt. We do not always need the performance of a BB engine. The RPMs we run at, especially when using a breaking run, are lower, and a BB front end is not needed. Also, it's usually true that a bushing engine will be lighter in weight than the same engine with a BB.

Now Bill,

There are certain things that have to be experienced at least once or twice in life, New cars,girlfriends or wives, houses,jobs etc. But the only real thing that counts is that new engine that you just hadda have.

Terrence Durrill · « **Reply #32 on:** January 05, 2012, 10:11:42 PM »

I like the Fox .35 on the Top Flite kit version of the Flite Streak....it makes a real nice sport flier and will easily fly the entire pattern. If you are into something a little faster and more lively, leave the landing gear off and use the Johnson....it makes a nice extra fast sport flier (even with landing gear on the plane).

Robert Zambelli · « **Reply #33 on:** January 06, 2012, 06:14:20 AM »

The Flite Streak will fly well with a variety of engines. Around fifteen years ago, I found a kit at a swap meet and the only mod I made was a two-wheeled landing gear.
The first engine to pull it was an OS 20 four stroke. The plane flew surprisingly well, would fly the pattern and was a truly fun sport plane.
Then a Fox 35 stunt and it flew even better, the extra power allowing longer lines and better performance in the wind. As I recall, the Fox 35 was shown on the original plans.
I then fitted a single wheel gear and a low-time silver case Fox Combat Special, the same setup I used when the FS first came out. Went like hell and was just plain fun to wring out and show off a bit.
Next came a MK V Combat Special. More speed, more power, more fun.
The last engine to fly it was a Rossi 20. Running 40% nitro and a 7-6 APC prop, the combination was just plain scary. It actually flew faster than with any of the Foxes. It met it demise when the outboard wing exploded during a violent pullout - the covering must have torn, allowing pressure inside the wing to blast it apart. There were splinters and bits of covering everywhere.
I guess the engine choice really depends on what you want to do with the plane. There is a lot of good advice here. Decide what best suits your needs and go with it. You can always experiment with different engines later.
You'll be pleased to see how well the plane performs on a variety of powerplants.

HI Charles,

If you cannot find a good OS .20FP, then get a .25LA. The LA is currently available, and the ,20FP can be found pretty quick. Brett Buck has a phenomenal set up that I use for the .20FP. All stock and use the E-2030 muffler with the APC 9X4 prop. Closest thing you can get to an actual pipe run with a muffler engine!

Bill,

I followed your previous advice. I purchased an OS .20 FP.

Thing is, it had a R/C carb. I purchased a OS .20 venturi and it didn't fit?

In fact, stupid me, I already had one. Got two now!

Is there a bushing pressed into the case for the R/C carb that can be removed so the venturi fits?

The .20 looks like a small engine.

Charles

EddyR · « **Reply #38 on:** February 08, 2012, 02:06:46 PM »

Everthing above is true,BUT,

but back when they came out and all we had was kits we used Fox 35's on them for Sunday afternoon flying. The "we" is me and my friends. That "we" would be about ten guys. Those who wanted to go to combat contest made the nose stronger with better plywood and used hot combat motors.
I never has a nose come off unless I crashed it. The nose can be made better than stock and I would do that now if I was going to build one. They are fast even with old worn out Fox35's on them. We used a the KaPac 2.3 ounce tank and it fit OK. For Combat I used what I thought was a better choice.

Did you order the venturi from Tower? If so, it is for the FP. If you got it some where else it is probably for the old .20S. Basically none of those parts swap.

The .20FP may look small but with the stated set up, it will more than power a Flite Streak.

Kenneth Cook's ratty Streak powered by a Fox 35 Mark 111 on bladder is my all time favorite. I've owned and seen many. Own a few at the moment. None equal the raucous pure fun of that black and orange ugly mean bird. Always gets my attention. Love it. Even tho I've never even flown it. Why not. Come to think of it. I want to fly that thing, Ken. It's evident how a Streak configured like that was a competitive combat model, even against the first few generations of wings.

HI Charles,

With the development of engines over the past 20 years or so, the LA .25 run in a wet 2 is stronger than the Fox .35. A better (easier) set up to run. The old engines will not match the new ones in producing power.

I fly my Top Flite Flite Streaks (original kits) with the Fox .35 stunt and they do just fine. The only other engine I would consider would be my 1958 Fox Blackhead Combat Special which would also be a reasonable choice since, George Aldrich, who designed this plane, designed it for that engine. It is a great old time, nostalgia, backyard or schoolyard flier.......just my opinion........TDurrill
