150MPH WITH FOX ENGINE???
Is it possible to make an airframe to go 150mph with your stock Fox Eagle .40 engine?
Why I chose fox engine? Well its a very weak engine. if you can get 150mph in level flight no wind with a fox, imagine what an MB Profi would do lol[>:]

Some Foxes fun pretty good...don't ask me which ones though?!
If you had one of the old "Quickie" .40's maybe 120-130 but 150?
Guess it would depend on the airframe...
I have an old .45 ABC...got it back in the late 70's...it's strong, but not that strong.

RE: 150MPH WITH FOX ENGINE???
Back in the 1988/89 time frame when I tinkered with the Fox Q-500 428 engine, no doubt I got the planes up to the 150mph range in level flight.
That is..... those times I got the engine to stage on the muffler and stay there without getting hot.
Not sure what a current Fox .46 ABC can do..... but who knows.
We do know, that a well prepared Shrike with a SJ-50 on it will make it up around 150 mph. So perhaps, a point of reference.

Do the math!!! rpm X pitch,,,,etc.. the formula is on here somewhere.

If you could have an airfram that has the very low drag raito. The frame only weighting 2lbs, and a 3+ horesepower engine....
Well you never know.
As you can tell I love to push the envelope.

Sorry but that was just to see if the engne can turn said prop enough to reach said speed. Air frame and drag are a whole other can of worms

RE: 150MPH WITH FOX ENGINE???
FOX engines are by far the worst engines I have ever dealt with. I bought 2 planes on RCU that came with them and eventually had to rip both of them out. The engines would stop running at the worst opportune times (such as during rotation or over the woods). Nobody at the field could tune away the problems and the fuel tank was set up properly too, so it must have been the engines.
In terms of reliability and durability of all the engines I've owned, it has to be 1) West, 2) OS, 3) Rossi and 4) MVVS at the top, then 5) Jett (sorry Jett-fanatics, my Jett .50 has started to poop out on me ) , then 6) Magnum and 7) GMS in the lower middle and finally 8) FOX

RE: 150MPH WITH FOX ENGINE???
I don't think any other engine company has ruled over any AMA event for so many years straight. The FOX .36 dominated AMA C/L combat for over 30 years because of its' light weight [8 ozs] and it turned a 6 pitch prop well enough to do 120 mph hooked up to a pair of 100 pount test cables. The planes seem to pick up some speed from that point after the lines have been severed.
Jett and K&B came out with .35s and neither one out did the FOX, they never caught on. It wasn't until Nelson got involved that the FOX finally was dethroned. 99% of the RC community don't know about this little niche of the hobby but when it came to power to weight and toughness, FOX ruled for quite awhile....at least here.
The FOX COMBAT SPECIALS had tapered liners and great compression hot. Their RC .40 cousins did not have the same cylinder taper and would flame out after the cylinder expanded too far. For FOX, it was / is a question of being able to survive as a US based company that pays their workers a liveable wage, possibly with equipment that isn't as capable as what you find in the Oriental factories.

I would agree with the Fox its just a weakling compaired to today standards in speed. Thats why I chose the Fox for this topic. Its a crapy engine comparied to todays standard in speed, if you could get an airframe to do 150mph thats really good for a Fox engine.
