Default Sudden urge for some cheap speed... (Shrike .10)

Tonight, while fiddeling with the engine of my Magnum, I suddely got an urge for some really cheap, simple, small and uncomplicated speed...

I was thinking about a Shrike 10 with this for an engine:

It is an MVVS .15 with a straight venturi... it should be good for 26000 rpm on the appropriate pipe and prop.

What do you guys think? Is the little .15 big enough for this .10 size airplane, or do I need more cubic inches? Remember this little engine puts out roughly twice the power the average engine in its class puts out...

APC has a range of pylon props for .10-.15 sized engines... they are 6.5" in diameter... will they produce enough thrust to speed up this Shrike or would I really have to step to the slower 7 or 8" props?

Any Shrike 10 flyers out there?

And while we're at the subject... how would the 1/2A Shrike react to this engine...? I suspect it would turn out to be way nose heavy... but fast...

Never mind guys...

I did a forum search, and it turns out that a Shrike .10 is flies LAME on a .15...
So I guess it is going to be a 1/2A Shrike... now this is going to be interesting with that "big block engine" up front...

Why don't you blow up one of these to your size likings. Can't be too expensive, durable, and ought to fly purty hot.

Here's the thread http://www.rccombat.com/forum_2000/t...rplane+Designs

you can put any engine in a plane if you know its going to be a heavy engine when building it...just move the firewall back. I am in the process of putting a cheap .40 on my already built shrike .15 so I can't really move the firewall too easy so I just stuck the servos and battery all the way in the back and I mean all the way....the servos are outside of the compartment in the little (usually sealed) space behind the main compartment. I think I will come out about 1/4" to 1/2" in front of CG. I am not reinforcing anything b/c I don't feel like ripping it apart and strengthening it...and I had a hole in my fuel tank which soaked the whole plane so I'll see if I can rip the wings off then get another one and build it for a .40 and slim down the wings....maybe make the main spar carbon fiber and fully sheet it. That delta spad looks interesting too but I'm already working on 3 planes right now.

26K is lame? I guess it depends on the prop size and the airframe. Just how big is the shrike 10? And the prop for that matter?

A 6*6 at 26k give a pitch speed of 149 mph and 62 ozs of thrust. That's way more than enough for a 2-3 pound slick plane.

Well... the Shrike 10 is about the same size as my Magnum... at least the wing is...

The Shrike has a slightly larger wingspan than the Magnum, wing shape is about the same, I wouldn't be surprised if the Shrike had a fair bit more area than the Magnum, as it is basically a flying wing...

The Shrike is undoubtedly a fair bit lighter compared to the Magnum... but still, imagine a Magnum on a .15 engine: boring (that is if you were capable of keeping it aloft)
I did a search, and people are putting anything from a .15 to a .40 on their Shrike 10, so even a really hot .15 would put me at the rear of the pack... and I don't want that

If I were able to speed up the little 1/2A Shrike to an honest 130-140mph I think I would have a very interesting plane to fly...

didn't realize it was that big. Also, didn't see the sig. Obviously, a fellow revver needs big power.

I just bought one built. (Shrike)

Can anyone tell me the throws?

Also, there is an OS 25 in it. Will this be sufficient?

A good light built 10 size shrike with a pipe and a 25 FX will do near that 130mph mark. Mine had a 25 FSR, no pipe, and i didnt shroud the motor in and it still went well over 100. Your ligther, more powerful 15, without the weight of a servo if piped right and cowled in good and tight would get you that speed i am sure.


I think a good 0s 32 piped, or even Irvine's .34(is that right) piped on a shrike 10 would be awesome. SOMEONE do this.


BTW, anyone know anything about BRATT motors? I have had 2 of the 28's. just put the latest one on a wonder and it moves along good.

JOE MAD,
the best way to get a shike to go fast is keep it light. gap seal hinges sand all trailing edges sharp , same with the fins

Crazy,


I didnt add any weight or move the firewall. I did add 2 servos to the wing and put them as far back as I could and put the attery behind the servo mounts where the wing and elevator servo go. Yes, i had to put the abttering in during the building process, but it came out perfect.

Any of you guys ever had problems dealing with Lanier RC?

I ordered me a 1/2A shrike almost 2 months ago (the day after I started this thread) and it still hasn't arrived...

The "package fulfiller" (Mark's Hobby Warehouse in Pittsburgh PA) says he has shipped me out a new one about three weeks ago and that one hasn't arrived yet either...

I'm starting to get annoyed...

Yesterday I got an email from Lanier about them "needing my feedback"...
They wanted to know if I was happy with my recent shopping experience...
I guess not... the flying season will be over when this thing is ready... that is if it ever arrives...
