Default Patriot 40 engine advice

hey guys,
i recently got lucky in my long search to find one of these after having to sell the kit i had several years ago.
at that time i was going to use an OS 45FSR.
right now i have an OS 45 FSR NIB, but i see the Jett 50 is the hot setup from the searches i've done.
i will set this bird up with retracts.
i want to fly this plane a lot, and i also want a good Sunday flier that will not be a knee knocker to land on our aphalt runway.

i don't always want to go full ballistic speed, but then again i will want this bird to be able to put on the show whereas i can scare the Cr@p out of a couple of my buddies

please help me make the right choice here.

Hi Mike,

I voted for the Jett 50 wich is the one I have on my Patriot right now. However, I'm thinking on changing the covering (old) and dropping a Jett 60LX in there.

Regards,
Doug.

well thx for the reply Doug.
i guess my concerns were about overall weight and handling.
i just sold the OS anyways.

if and when you have time, please tell me how you setup the fuel system and retracts (brand).

thx
mike

OK i see it now on Jett's site.
the 50 weighs 16.4 ounces with the muffler.
this is where i was concerned earlier as i thought it was 16.4 plus a muffler giving me the idea that the Jett was almost 1/2 lb heavier.
this turns out to be only 2 1/2 ounces more.
LOL.been a while guys.

thx for the reply funflyer.

now if i could just see some of your guys fuel tank setups and figure out which servos would be best i'd be in business.

after looking through the specs and past threads it became real easy to justify ordering a Jett.
this should be one fun airplane

personally I'd skip the full pipe and use the 1/4 wave pipe that comes with it.

I agree CP, that plane was pretty sick. The purple scheme was cool too.

put the FSR on e-barf, you will get a good buck for it since it is NIB

then put your Jett 50 or 60 in it!

sold the FSR in about 10 minutes on another site, and glad it went to someone who will appreciate it.

i thought about the 60L, but stepped back to the 50 as i think it is going to be a good all around screamer.
i've been told though that Dub is testing a new engine that may be more of a Revver, and is between the 50 and 60.........if so i'll naturally want it.

one thing about this speed forum, you guys rock.........everyone is so in tune to what is going on that they don't argue.
the enthusiasm here has overwhelmed me.
i've now found 2 NIB Patriot kits, ordered the BSE 50 and Spring airs.
sold a bunch of stuff, and spent it all and then some

haven't been this enthused since the day i stepped back into RC a couple years ago.

i've not seen a Jett engine at our field so it is going to fun to firs the 50 up and let it scream..............yeah baby

Default RE: Patriot 40 engine advice

more questions,

instead of starting another thread i figure i'll keep it here.

i haven't rec'vd the kits yet, but am wondering about engine mount, spinner and feul tank.

after reading about the bubble jet tanks it seems to be the best option for consistent running, but i'm all ears.

spinner is obviously best if i go with Jett, but what size?

engine mount, suggestions?
i see the ones on Jett's site, but not sure which one to get. not sure if the one in the kit is useable for this engine.

servos, i fly with Futaba radio and have S9202's,9101's, 3102's and 2 of the 9602's which have mounting lugs to be used if i want to side mount, or they can be cut off to mount vertically......i was thinking of these for the ailerons.

i'd hate to lose the plane in the air because of the wrong servo choice so much help needed here.

Hi Mike,

Unfortunately, when I got my Patriot (6 years ago) it was already built with a fixed landing gear (I know it sucks) but I’ve had lots of fun with it all these years.

For fuel tank, I use a Hayes 12oz slimline tank, never had a problem with it (I wish I can fit a hopper tank in there but there’s no room for that).

For years I only use S3001 servos all around, now I’m using S9001’s.

Mike,(my personal opinion) take the time to break-in that engine on a test stand, it’s a very powerful engine, it needs plenty of fuel, back it down from peak rpm about 800-900rpm on the ground because its really going to unload in the air, also make sure you keep an eye on the head bolts.

My Jett 50 is 6 years old, still with the original bearings. Not as strong as it was when new, but it was clocked at 119mph not long ago with an APC 9x9 prop.

As a side note: I removed the 2 side intake that comes with the kit, and it flies much better (less drag).

Man... you're going to have lots of fun with this model, enjoy it!

Regards,
Doug.

Love the current poll result !

Nota: FSR were very good engines, much more durable than today's BS (ABL liners, etc...) thanks to true chrome plating...

WOW...........for some reason when you guys mentioned the 60, i was only looking at the specs for the 60L.........then i somehow opened my eyes and see the 60LX at the bottom of the listing...........18,000 RPM's with a 10x6? holy moly

is the 60LX as user friendly as the 50?

I never had the 50, but the 60LX is not hard to adjust if you use the recommended prop size.

18,000 rpm with a 10x6 works out to 100 mph. The fastest Patriot radar readings I've heard of were in the 170s......how do you get there from here?
IIRC the fast times were made with 10x7 props and an engine that unloaded extremely well..

not really looking to go 170........and if so i believe it would take way more than the 60LX to do it................right?

suggestions here were to get the 60LX instead of the 50.
but i just got an email from Dub, he is recommending the 55LX................yes, the 55LX.

i do plan on running different props though, i was just adding that the 60 will pull a 10x6 1K faster than the 50.

The readings were made with a Rossi .53........but I think they were peak readings at the base of a dive.

As far as the Jett.55 is concerned, if they are replacing an existing model with this engine, it must be pretty good.

I have no idea why you wouldn't want to go 170...this isn't the Extreme Pattern Plane Forum?

I think the 60LX has been superceded with a new engine, designed to be a little less finicky or something as some people found the 60LX. I think Bob posted something around here somewhere or someone else did, I'll go look.
