Couldn't resist...

LA= Low Achievement.

LoL
good one!

There's a few more...

ASP: Air Sucking Pig

FP: F___'n Pathetic


I can't help myself...

i had a APS 36, the bearings lasted 10 flights! i was told i was using the wrong fuel, Prosynth 5% not sommit with castor!!!!! like that would make a difference in 10 flights, 10 short flights, 4Oz tank in a fun fly
i have two Magnum 36's, both last about 10 months before they have to go back
the Magnum 15 is still good
the SC 15 was ok, wore out after faily good service, never worked right since the new piston conrod liner went in.
Irvine 36, good engine, lasted a long time
Leo 37 great engine, still going great
MVVS dosn't matter what size, all are bullet proof.
West, oooooooooooh i wet me self

Here's one for ya race

OS= overpriced S**t

Some years ago I designed and flew a little .09 powered model for the old "Galloping Ghost" control system. When the small propo systems came along I continued to fly it with a .15 engine, using rudder elevator and engine control only for many years. It could and did do all the manuevers nicely, including level inverted flight - with a flat bottom wing, yet. It was very fast, very touchy and would never be classified as slow or puttering. I still have it in my shop and one day I will probably put a more modern radio in it and fly it again.

My buddy built two Quickie Bipe's from RCM plans and powered them with OS .15FP's. They are great flying planes and the FP is a great engine if you can get it. I have one of the Bipes and have an FP in the box just waiting for a new project.

It wasn't fair of me to poke fun at the FP engines...

In all actuality, they were a fine motor. Perfect for the beginner.

They ran well even when they shouldn't have...they were reliable and consistent and that makes it a "10" where the beginner is concerned.

Interestingly enough...the .40FP really liked a 12" prop. Sounds crazy but they ran very well with them...a little extra thrust on the trainer and no strain/overheat from the motor.

MrMulligan,

I have horded 2 NIB fp .15's from ebay and plan to build a Pica twin mustang. These OS engines are the first I'v ever had that would actually hold an idle and respond to throttle reliably. I will be using a Macs tuned pipe system with them for speed runs. I know that won't look scale but as fast as this plane is going to fly,,, You may not notice this deviation from scale...

ZB

Pipes on FP's? What kind of exhaust timing do those motors have?

I'd be interested to see if there was ANY gain in performance with an FP on a pipe. Since the pipe/header cost more than the engine....??????

'race

Race,,,, It's only money. (I don't use LOL) I only have 1 pipe system now and have not tuned it. I can say that with the full header and pipe attached, it sure as heck sounds like some business is going on. Also I noticed the throttle response was quicker. Also, I did not pay more for the pipe/header than I did for the engine. Try to find a NIB FP .15 and tell me how much you have to pay. I hated these things years ago because I thought they were cheap. After finally getting one, I think I had misjudged these engines. FWIW. I also found 2 NIB FP .10's and look forward to mounting them some time. BTW,,, The .15 header and pipe system will work with them also.

ZB...

If it's only money...PM me and I'll give you my mailing address...send as much as you like! <GGGG>

Ebay is great...but it's also the best place I know of to pay 50.00 for an engine barely worth 20.00.

Ever consider a mousse can muffler for the FP? Cheaper than a pipe, and lighter too.

I've owned quite a few engines, and the O.S. .15 FP is my all time favorite. Not a powerhouse; but quiet, reliable, and fuel efficient. I've got mine on a 99 in. Dynaflite Butterfly, that I use for training. The plane weighs around 3 lbs., and will ROG off our rough, grass field with an 8-4 prop. I usually get 10-12 minute flights with 2 oz. of fuel. I've had the engine on four (4) planes, and it's never quit on me.

Just goes to show you that there is something to be said about a dowdy little motor that just runs. No pretentions to greatness...it just works.

Great fun and enjoyment to be had with simplicity.

'race

my first engine was a 25 FP, ran forever, went ok on a 9x6, getting old now, overheats a bit last time i tried to use it, but it still worked after sitting in a box for 4 years.

scary but here, all they sell is LA and ASP
Aaaaa!

oh dear lol
i was at a recent show, wanted to buy TWO Leo 37sf's from the Just engines stand, except they sent a rep who only had Moki'sand APS's he said the ASP 36 was far better than any other 36 blah blah blah,
i said i'd rather pay for a Leo than get two ASP's for free, i told him about my bearings and how i have the Magnum clones and their s*** too,
using the wrong fuel he said, Weston won't let out their oil content figures,
well it aint that hard to work it out i said, all these castor people live in the past, and if you check the weston site their fuel has been ok'd by the ASP,Magum ect ect ect ect ect for use.
the fuels no good he said, you want castor
no, the engines no good, if it can't run on this fuel then the castor is hiding and masking its faults, its a s*** engine and i won't touch it, i run one fuel and if the engine don;t like it, i'll get another engine, im surprised you've not brought the most popular engine you currently sell, i wanted two, never mind, bye.

just found a shop that sells FP
well...
its the same price as the LA
but go for FP right????
wuts the difference???

ya know.. i dun know that, both plain bearing , ones blue, know which i'd rather have, but don't know why LOL

Beware trying to coax too much out of your plain bearing FP's. I ran my .15FP on 25% for less than half a gallon and trashed the big end, bronze bush and crankshaft.

I believe the only real difference between the LA and the FP's(aside from the pretty blue anodize) is that pesky remote needle valve.

Everybody loves those remote NV's right? <GGGG>
