OS.10FP OS.15FP OS.15LA will keep it light great for "low and slow" flying.
OS .20FP and .25FP will get a little more zip.
OS .15CV performs well
OS .25FX whips around the patch very well.
OS .32SX for going nuts
Jett .30 FIRE for going ballistic!
Yep, I even kit bashed a Woner into a twin. Two O.S. .15 FP

RE: egine for sig wonder
There are such a wide range to choose from - what choices do you have in a 0.15 to 0.25 glow?
I've had everything from OS 0.15 to OS 0.25fx in them - the 25fx was alittle heavy but ballistic

all i have at the moment is a thunder tiger .15gp

It will fly well, simliar in power and weight to the OS .15FP
servos: I used:a Hitec: HS425BB for the ailerons HS-81 throttle HS-85MG elevator.
I alter the build of the kit, to bolt the stab down to the fuse not glue it and eliminate the servo access hatch.
I put both elevator and throttle servos aft of F-4. under the stab. a longer throttle cable will be needed.
a 4 oz. slant nose Sullivan fuel tank will fit and you can fly a long time on it with your TT .15gp

I have one with a 15 LA that does about 85 (edit: from a radar gun). It's a blast to fly, and probably the most fun one could have with three ounces of glow fuel.
Also have another one nearly finished with a 25FX, but it's been hanging on the wall waiting for me to finish for a while now.

Your .15 is just fine and it will fly well. If you want to put more horsepower on it later, then go for it! But for now why not just use the GP? If you're gonna buy a motor for more get up and go, well then, .25 and up IMHO.

RE: egine for sig wonder
step 5 ??? cant find my old assembly manual
but take a moment and find the TE trailing edge stock...then scan forward thru the manual and they tell you cut, notch, out some of the TE between the cap strips for the torque rods.
Well look at the plans and your stock and cut 2 notches that will be the clearance for the torque rods. No carving later!
