Default My New Patriot Which Engine?

Well guys I was lucky enough to pick up a new Patriot at the LHS this weekend. Considering Tower was out of them when I called I was impressed that I found one and a set of Hobbico 3 gear mechanical retracts to go with the kit.

Now I need to buy an engine for my plane. I was considering an OS 50 SX because I have a new pre tuned Macs header and pipe for a 46 FX and I know that the exhaust ports are the same. But I am not sure about putting a pipe on a ringed engine. So I am looking at a Jett 50 with a SS Muffler.
I am fiberglassing and painting the plane( before you all moan dont worry I have been glassing and painting for 16+ years and can do it very lightly) I will be spraying it with PPG Lacquer and 2 part gloss clear.
So what do you guys reccomend for an engine on the Patriot for all out speed but also for reliability and ease of operation. Does the Jett 50 out perform a piped OS 50 SX? Any suggestions of ideas are appreciated.
Joe

Default Yup...

The Jett 50 is THE best choice

Also good options:

YS-45
Webra speed 50
MVVS 49
Rossi/Morris 53

The OS 50 is supposedly a sweet motor but there are a few (see above..) that I would rank higher for this application.

Keep us posted,
james

Default Patriot Engines

Thanks James, I had also thought about the YS 45 side exhaust with my 7.5cc Macs pipe. I am not sure I will need to do some thinking. The Jet is nice because I dont need to mess with a tuned pipe with its SS muffler. And parts are easy to get. James have you run a Jett 50 yourself? Just curious as I know that the YS is a really hot engine I have a NIB 61 AR that I need to build a King Kobra for?
Thanks Joe

Default My New Patriot Which Engine?

Try a search and you'll find tons of good advice on the Patriot. I am almost finished building my Patriot and due to the advice of others on this board, I decided to power it with a Jett .50, I'll post some pics when shes done. I decided not to go with retracts, the field I fly off of is fairly rough, and I just did not want the extra troubles. Im sure i'll be sacraficing a few mph's, but thats life.

Default Sounds good folks!

Viper- I have never had a Jett (someday.. ) I know that the YS-45 with the 7.5 cc pipe flies the Combat Models pusher VERY WELL and it ways 7-8 lbs. If you don't already have either though, the YS+pipe+ header is about what a Jett 50 would cost or close enough so...

Nothing wrong with the OS-50 but if you are shopping still ($$) go with the above-

Gixxer- You are the bomb! The Jett 50 is supposed to be insane on the Patriot...

Need 4 speed- That MDS is is a powerful engine from what I have heard/read, and if you have it lying around + the Macs pipe... That sounds pretty good! Is it heavy??

Man, I need to get my Patriots back in the air- I just traded a YS-45 for a 4 stroker now I have 2 patriots and the only close engine I have is a TT Pro 46 (Unless I molest my Lanier F-4 for the YS on that..)

You guys motivate me to get rolling on it and I think we should have a "Patriot Forum" on here

Bring 'em in hot-

james

Default Engines

James, I have not bought an engine yet for my Patriot. But I do have a new pre tuned Macs Quite Pipe and header for an OS 46 FX. I know that I can get a new header to fit a YS 45 and I am really thinking about buying that engine. But the Jett is supposed to be killer in the Patriot as you say. So I dont know which engine to buy? I think that the OS 50 SX is probably out so its between the YS and the Jet.
BTW I have a NIB YS 61 AR thats never been mounted. I plan to put that in a Sig King Kobra or a Direct Connection F18 if I can ever find one.

Wow came out light Need and yes its okay to put your battery up front. If its under the fuel tank you may want to put it into a plastic baggie incase you have a fuel leak.

Default Patriot

I had several of those patriots, the fastest one was equipped with a YS-45, rear exhaust.

I raised the exhaust timing as far as I could, and it really killed the low end, almost impossible to taxi. It would turn an APC 9.5 X 8.5 N about 17,700 RPM on the ground. I think that plane could hit about 130 or so.

I think many people estimate their speeds to be a lot higher than they are actually going. There are a bunch of guys at my field with YS 91s in 40 size warbirds, I clock them with a digital Stalker at anywhere from 95 to 110 MPH. I had a Webra 120 in a World Zero, a 13X13 APC and it did maybe 130 as well.

Have fun.

Default Hmm..

I guess it just boils down to preference or cash as far as YS/Jett...

Can't lose with either one as you can see-

Keep us posted guys, and good luck with the MDS and pipe combo, should be good!

Default YS 45 Rear exhaust

Matt, can you remember which Macs header you used on your YS 45 rear exhaust in your Patriot? I am considering buying a YS 45 rear exhaust for my Patriot but I am curious which header clears the fuselage? I am guessing it would be Macs "Fuse Top Header" But I am curious.
Thanks Joe

Default Ressurected thread!

Wow- Just reading through old posts since I have 2 new Patriots in my Hangar-

My last one DID have a Jett-50 and was flat out awesome- But that engine is M.I.A. (Literally) so now I have a couple of options and if you folks are still around from this thread- maybe you can help me...

I WILL buy another SJ-50 but until then I have these to choose from:

OS-50SX (Hence revisiting this thread-)
K&B-48 (Screamin' 48)
YS-45 (No pipe as of now-)

What finally happened to those Patriots with the OS-50SX? I am getting this engine used and thought it would work well...

Cheers!
James

I had an MDS in mine, 58 though, and that wasn't sluggish, not by far![X(]

Still wish i had her. although I'm building a hybrid of the two. using the parts from both of the mid air victims to create a whole new plane

Definitely JETT .50 for all-out gettin' it and they are also very user-friendly. Next in line would be the YS .45.

I've heard of the JETT getting over 19,000 out of the box with a 8.75x7 prop.

Glorfindel,

For what it's worth, I don't like the APC 8.8 X 8.9. Granted, I tried it on a Quickie 500 racer and not a Patriot, but it just didn't "go" like other APC props. I much prefer the 8.75 X 9.0W and 8.8 X 9.25. You should give these a try and let us know what you think of them.

I hope you mean for the big Patriot[:-]
I am going to buy a new OS 50 SX for my Patriot and will use a Macs pre tuned header and quite pipe and retracts.

On the retracts has anyone had any problems with using a regular servo to operate the nosewheel retract unit? I guess I should just adjust the EPA throws too keep the servo from buzzing.
Thanks Viper
