Default Easier to build? - Shrike 10 or Sig Wonder?

Hi,

I'd like to build one of the two, either a .10 size Shrike 10 (already have the kit) or a Sig Wonder (willing to buy). Wanted to get some opinions from folks who've built both as to which one is easier to build and/or produces a nicer product with less effort.

Thanks,
Frank

SIG WONDER hands down!


Builds quick and EASY Detailed plans, PHOTO instruction manual, ALL the Hardware is included too!
Wing builds flat over plans, not through the fuse on spars.

Wonder hand launches better(larger fuse area to hold on to), flys slower but not as fast.

If you buy a wonder kit about 40.00 send me PM for building modifications.
like bolt on stab & no lower hatch, 3/16 sq basswoood L.E. with wrapover wing sheeting., dual rudders.

I have built Wonders with: OS.15 FP, OS.25FP, OS.25FX and two OS .15 FP.

I have to agree-I've built 'em both and I think the Wonder is easier to build. The Shrike construction is just kind of weird, not really difficult but plenty of opportunity to screw things up. Just my opinion.

SIG Wonder, way to go !

The Shrike will reach higher speeds. The Wonder has a very efficient but thick (draggy) wing section...

I have built both and I have to agree that the Wonder is an easier build. Although I didn't think the Shrike was that bad. If I remember right the Wonder came with hardware and the Shrike did not. Also, you don't have to worry about the Wonder folding its wings like apparently the Shrikes do. My Shrike folded its wings.[]

To be more accurate, you'd have to say : 'like apparently the OVERPOWERED Shrikes do.'

Never built a Shrike, but the Wonder is an easy build.

They both are about the same on the build but the Wonder sure was a lot easier to cover. As far as the Shrike wing goes just replace the balsa spars with spruce or bass wood, problem solved. Flying my Shrike with a 25 no problem, yank and bank.

I had the .10-15 Shrike with OS.25FP did not consider it OVERpowered but I did fold a wing.

added spruce doublers to the two spars and flew the snot out of it.

I know this because.... the FMA Rx battery went south on the 3rd flight one day...

the wreckage was found with no snot inside!

The .10-.15 Shrike as you call it, has a recommended engine size of .10 to .15. You've used a .25 => IT IS overpowered, by definition.

Default RE: Easier to build? - Shrike 10 or Sig Wonder?

rudders are good for wild snaps spins with aft CG limit,
rudder only at fulll throttle make the plane skid

I bolt the stab down with 10-32 nylon screws using wing mount block plenty of room and a 3rd screw into a block add between the fuse-sides & do not put hatch on aft lower fuse I just sheet the bottom and full length triange stock

add 3/8 triangle stock under the wingmounting blocks

wing ribs are 4 sheets with 4 diecut ribs each, ecah rib is a little different...
I stack the up on the wing spars and then sand them to match.

delete the 1/4" baalsa LE and use 3/16 square spruce for LE, it fits flush to the fish mouth in the ribs ... DON'T trim wing 3" sheeting if if straight to 2-3/4 as instructed this way sheet wrap over the top of LE and has better bond.
(if supplied balsa is curved then you will need to buy 1/6 x 4 x 36 bala stock and trim to size...)
plans call for butting the wing sheeting to the 1/4" LE but I have found it is a difficult task to do with out waves.
a stronger straigher LE is the result

the trailing edge stock is be pre-notched for the torque rods, instruction ask you to carve a groove out after wing is assembled.

install balsa or harwood blocks inside the wing under the servo for solid servo mounting screws then sheet the wing

I put 2 mini servos on hardwood rails under the stab for elevator and throttle cutting square hole thru fuse sides to locate rails...
you will need to place servo on plans to plot out location, 1/4 triangle stock used around 3 sides of the se rails for support/strength.

Default RE: Easier to build? - Shrike 10 or Sig Wonder?

I have been flying three years now,and my first kit was a Shrike 10.
I modified it a lot. Engine is an OS 32 SX,8x8 prop,Macs tune pipe
and Jet Bubble Tank 6oz..
Sense the build and flown a few times,I have changed the spinner to a True Turn.
To make it lighter I would change my servos to lighter ones and go with a lighter
battery from 6v to 4.8v(750mah).I havn't changed that sense the plane is fast enough.
Our radar gun at the field will not pick up the plane,but most everyone agrees its
flying 125mph+.I found it to be an easy build and maybe the Wonder might be easier.

Sig Wonder,
I have built both. The Wonder builds more like a conventional aircraft. The Shrike is just different but ok to build. I'm flying my current Wonder with a norvell 25.

I hope you replace the balsa spars with spruce or basswood for strength.

I folded a wing on my Shrike 10 with just a .25 FP on it.

Yes I did..
I also have a carbon Fiber rod going from wing tip to wing tip.
I should note to that my instructor crash the plane .It hit the ground
doing 80 to 100mph..ripped the whole front off,but wings and everything else
stayed intact ,,not a scratch .
It was an easy fix , and ready to fly again...

I am currently covering my Wonder. I have an OS 15cv-a mounted on it, and am going to use mini servos.

This is the first kit I have built in almost 9 years. I did have a bit of troulbe with the sheeting on the wing, had trouble with the leading edge stay down.

And I have forgoten how bad I was at covering planes.

The butt joint for the wing sheeting on the Wonder is a pain in the *****!

What I do is use 3/16 square spruce in place of the 1/4" sq balsa LE stock. Note the sheeting is 1/16 thick.

I do not trim the 3" wide wing sheeting to 2 3/4", I need all of its width.

I put the sheeting over the top of the spruce and ribs.

Default RE: Easier to build? - Shrike 10 or Sig Wonder?

I have built 3 shrike 10's so far..the first one had an OS .32 and the second had an RJL/Cox conquest .15 and this last one I have is just an upgraded exhaust system (tuned pipe)on the conquest. The tradeoff of speed with the .15 versus the .32 is stability and better wing loading and landing characteristics..but now with the tuned pipe, I may regain most of that .32 speed without the weight. I also just started workin on a shrike 40..I see now that you can't get these kits anymore?..if so, I'm glad that I have one of each. If anyone knows where you can buy new kits please let me know....
