Engine recommendation

Many years ago, I used Fox .15 and .19 engines, and I still have my teedee
..49 and .51 engines (I paid $20 for my Fox .19 nib!).

What are good engines in the .15 to .25 range today? I see a lot of old fox
engines on eBay, are they a better deal then getting something new? Who
makes good engines these days?

Anything that works reliably is worth using.

Apart from a few classics, most old engines don't fetch much secondhand.

Mt limited forays into IC engines recently reveal that no one has ever
accused an OS engine of being unreliable or of poor quality. Probably e
engine of choice if you don't want to get involved in detail

Electrics are getting quite attractive in that size of model.
Performance has pretty much hit parity with sport motors, and there's a
lot of folk out there who know the ins and outs.

A motor, controller and battery will set you back quite a ways, but if
you fly often you'll save it back on fuel. The only thing that you'll
really miss out on is the noise and having to clean the guk off of your
airframe at the end of the day.

Ah, but that is half the fun! It's like using charcoal versus gas to BBQ.
I'd never use gas to BBQ, and I'll probably never fly an electric plane

Re: Engine recommendation

I agree ... I finally broke down and bought a gas grill, but I kept my
charcoal grill too. Now my wife and I both agree that food cooked over
charcoal tastes so much better. Use the gas grill for emergencies only (or
when I'm too lazy).

With that said, I have an AP 15 Yellow Jacket. It is a great little R/C
engine, easy to run and very reliable, low cost too.

It's funny how some people just don't understand why miniature IC
engines are so much fun. As far as I'm concerned, saying that an
electric airplane flies as well as a glow powered one is like comparing
dry crackers to a gourmet meal.

The "old reliable", OS. Some newcomers that are good (in no particular
order ) - Thunder Tiger Pro series, Evolution, and with somewhat mixed
reviews (most reviews/letters/comments are quite good ) Magnum.

In a 4 stroke engine you will not go wrong with a Saito (I have 3 Saito
and 1 OS 4 stroke - all reliable runners ). In a 4 stroke, a 52 is
ABOUT equivalent to a 25 - 30 2 stroke, however they swing a larger prop
with ease.

How about K&B engines? I don't hear much about those, but they have been
around a long time. I've always used Cox for little engines, but Cox doesn't
make any bigger ones. I'm not sure what they make these days.

Well, have fun then -- I fly both electric and glow, and enjoy both.

I've had mixed experiences with Magnum over the years, but I've very happy
with my Magnum .15XLs. I think they're now XLA or XLS or some such, but I
believe it's still the same engine.

OTOH - if you want to buy a used Enya .15, I could make you a deal

There are some nice K&B engines in the lineup, although they are a bit
quirky compared to the more popular makes. If you're accustomed to
running Cox engines, you wouldn't have any trouble with the quirkier,
old fashioned engines such as Fox, K&B and their ilk.

There's that equivalence comparison again....

Saying that a 4 stroke 52 is ABOUT equivalent to a 25 or 30 2 stroke is
true only if you are talking about a situation that favors a 2 stroke.

If you have a sleek plane and you want it to go fast a 2 stroke will
give you better performance, and you will get the impression that a 4
stroke has to be bigger to get the job done.

If you have a biplane or other slow flying machine, a 4 stroke will do a
better job of accelerating and climbing than a 2 stroke of similar
displacement, in which case the 2 stroke would have to be bigger.

I love biplanes and old timers, and I always power them with 4 strokes.
Lightweight planes designed to go fast always get the lightest 2
stroke that will do the job.

If you liked the Fox .19, stick with it. Nothing 'modern' in a sport
engine beats it in the key performance measure for any aircraft
engine, power to weight ratio. The Magnum BB .15 comes closest if you
can't find a Fox in good condition. Not many engines made these days
in that size range that really perform, unless you get into $$$
exotics as used in FAI competitions. Downside to the Fox is noise
level. If that is a big issue where you fly, You might want to try
another muffler. I've used MVVS mufflers on Fox engines with good
results, but haven't tried them for fit on anything smaller than the
..40 - .50 range. A tuned pipe is another option that is both quieter
and produces more power. Mac's Products *may* still have TP headers
for the Fox.

I actually liked my Fox engines very much, but haven't had a lot of
experience with other engines. The .19 screamed, and the .15 was pretty
peppy. Noise? That is half the fun . I'm looking at Fox engines on eBay
right now, looks like there are tons of them available on a regular basis.
Anyone know how well old Fox engines hold up?
