Well what do you have???

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

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

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

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.

60-70 + but it small size makes it look faster, it will be very agile too.

I used an OS 25VF-DF Great combo

joeman784

what about an os 25 fp

Crazy4Flight

My Feedback: (540)

better than the .15

but if you have a .40 FP carb it fits the .25, install it! the 40's carb has a larger bore, also remove the baffle from the muffler

I am still covering my Wonder, I bought a new OS 15CV-A for mine. It is going to be a lot of fun once I am done!

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.

My two bits.

im stuck on step 5 what peice of wood do i put down... so confusing

Crazy4Flight

My Feedback: (540)

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!

I watched a gentleman fly one last spring at a funfly. It hat the OS32 in it. Did that thing RIP!!!! Wicked fast so agile and would glide and glide and glide.

That is what i would put in it if i had one.

Thanks for the info. I checked the Sig web site but they don't offer the manual online. I also tried to call them but I got a machine saying they were unavailable.

CG 2-5/16" and 2-7/16"
No high rates printed in the manual.

good luck,
