Default Shrike 40 arf / What engine?

I am going to get a shrike 40 arf for some cheap thrills , but after looking at the price of the dubb jett 50 at $260 all of a sudden it's not so cheap.
I am sure they are great engines but has any body used another engine with reasonable results and if so what was the engine and prop combo?
Thanks in advance...........JOHN

Heliforme:
Try a K & B 48 screemer with Jett or performance muffler. It will be close, for how long I don't know. This is one time you should bite the bullet and get a Jett 50. It ends up cheaper in the long run trying to find something close. My 50 is going into its 3rd year and running stronger than the first year. Others, a Irving, a K & B two OS's have hit the trash can after blowing up. When you adjust purchases for durability and quality, the Jett simply is the bese and, the most cost effective, period. Others I tried and were dogs were one MVVS 49 and one Rossi 53. In general, we are asking a sport engine to turn close to a race engine. In the real world, a engine designer can get only so much rpm out of a engine and still idle well. Right, I dont care how it idles, but the designer-manufactuurer does, and figures we are smart enough to buy a race engine for raceing applictions. We want both, and that is in the can not do collum. The sports jett engine used for sport applications is a great engine, idles so well, throttle response outstanding. Get their racilng engine for go fast applications, and prepair to be shocked when the thing first starts up. "Oh my God" comes into mind. 24-26K has a sound so sweet, just music to my ears. ENJOY

Thanks for the feed back
I am now wondering how much difference the sport jett vs the race version would make in speed?
Thanks............JOHN

I run a simple 46pro with a 9/7 prop. Its a 110 mph plane. If you have never had a Shrike before, this engine or some basic Tower 46 will be more than adequate and will be very impressive and a handful. I have some Jett's of various sizes. If you like the Shrike, then build a second with a Jett 50 in it.

Should be fine. The shrike can be a perfomer even with the worst of engines installed. (not yours) just making a point. Like the 40LA or something.

I have had 3 OS50SX engines, I have also sent all three back to OS with broken rings OS replaced all three and I use one on a 3D plane which has been great running at lower rpms with bigger props but running them fast they all had a short life. I sold the other two since they sent brand new in the box replacements, I'm not an OS hater in fact I have a few other OS engines that are great I just don't think this one was meant for high rpm operations this was just my experience so I'm sure others may have other opinions.

John,
I just finished putting together the ARF Shrike using a Jett .50 with their red UltraThrust style muffler. It's as fast as I want to go without a brain transplant to a much younger version. You'll never be happy now; knowing the Jett is so good. I have several OS 50SX and while they're good engines they ain't nothing like a Jett 50. Nothing.

A few hints, if you want them. First, watch out for sharp vearing to the left if you take off with full power. If you're flying right pattern that means you're headed for the spectators. Avoiding the left turning tendency is easy just by taking it easy on take off untill the plane gets up to speed in the climb out phase. Second, don't let it get too far away. It does that very quickly and is hard to see. It's small and hard to see. Third, get used to it's slow speed ways while you're at altitude. It will stall without warning. It's made for speed and it does that very well.

Have fun.

Thanks ArthurD for the INFO
Some questions however
What prop / Fuel/ are you using and did you get a Tach reading?
All do you think it will hand launchok i am not going to put on the gear just ex drag.
Thanks..........JOHN

If you go with the Jett 50 you may want to consider the SS tuned muffler that is an option. It is a little shorter and tuned for higher rpm. Mine turned an APC 9x8 just over 18,000 static on Powermaster 15%. I prefered someone to hand launch mine for me, especially if there was much wind. A gental shove into the wind nose high and it was gone. With out gear it will be hard to find a plane at your field that will stay up.

I'm using a 10 X 7 APC. I didn't tach it, just used the suggested-by-Jett prop size and flew it. It sounds like it's just right; gets up on the pipe quickly.

Consider using the gear initially and get used to it before going hand launch. I went something a little in-between by replacing the fat wheels with small foam wheels and reshaping them with a belt sander to be more aerodynamic. You'd have to be faced with severe competition to want more speed from the package. It's all I can handle. I don't find it easy to fly at low speeds, i.e., hand launching but you may be a better pilot or have a stronger thrower friend then I.

Fuel is 15% by Morgan, green stuff, Omega Cool-Power.

Glow plug........
Dubb says the engine likes hot plugs and advised the McCoy. He is right. The engine thrives on it. Make sure to tighten it really tight; it'll shake out of you don't. Tighten it again with the engine hot - important.

Happy flying! I'd like to hear how it does in the air and your final set-up.

John,

Your best best for the ARF if you are working a budget is probably a simple Jett SJ-46 Cost a few $$ less than the SJ-50 and most likely you will not notice any difference in power on this aircraft. Break the engine in, install a standard APC 9x7 prop, set it 500 rpm down from peak, and fly it.

Go to the jett website and look for the Hangar Sale page - request a current list. Might be something on there of interest to you. Sometimes there are engines combined with quickee mufflers or SS muffler which are perfect setups for the Shrike.

For a good budget choice, get a Thunder Tiger .46 and you can bolt on a jett-stream muffler to it later on if you want it to move.

The Rossi .40 morris usually has on sale is a good option as well - just be careful with the CG.

Bob

Everything good is already taken (Posted) so...

Side notes- The OS-50SX and Tower muffler was a beautiful engine IMHO-
The TT Pro-46 is the best banf for the buck IMHO
The K&B is under-rated but a tad heavy IMHO
The Jett-50 has no substitute IMHO

I got an excellent buy on a 80% completed Shrike .40 kit, not ARF. Look at putting an OS .46AX in it, but it is going to be a very very tight squeeze.

My flying skills are "medium" - I an NOT looking for terror white knuckle speed. I'm looking for a fun aircraft. (I am NOT going to use gear. I have no problem with combat planes, though they may have more lift than the Shrike.)

I know you speed deamons are going to kill me, but what if I put something like a GWS .32 in the plane. I did a lot of searching, and everything I found is on going faster and fast verticle. I'm looking sport plane.

If I go to a OS .40, it is the exact same size as the .46 AX, so I haven't gained anything. I've also looked at the GWS .40 and Super Tigre .40, but I'm not saving anything on size or weight.

Would appreciate feed-back.

Thanks,
Bill

The GWS .32 will be pleanty of power to fly it well.

Give it a try.

Lots of Shrikes out there flyin with .40 size power. Seems to fit ok, but you do have to keep the CG in mind during setup.

Blue,
Based on your expectations, you will be happy. I run a Jett 60 and it's a hand full. The covering blows off, litterally. The whole fuse top covering came off the last time I flew it. Must have started loosening from exhaust oil and I didn't catch it in time. You'll have fun and it should be impressive. When and or if you want more speed, the Jett is a fine way to go. One of the best things about Jett is you have immediate, knowledgeable and willing help right here in the forum. Take advantage of it. They'll even talk to you about other manufacturer's engines. Guess they know you'll eventually not be able to resist the bang of a Jett. I wasn't.

Be sure to play around with different props to get all the goodie out of the AX. Don't be afraid to let it rev up. It revs higher and produces more power than the 46FX. Others may be more experianced with exactly which prop to use. I'd suggest you think about APC's in sizes like 10X6, 9X7, maybe 9X8

Hey Arthur:

Are you still trying to make planes go faster? Give it up...Hee Hee

If you want fast...buy a rocket.
