I have built a few kits over the years so some little faults are no problem, but as the build on my 1/6th J3 Cub progresses i am finding plenty of faults with part size, part shape, and the wood in general.

One main spar had a distinct taper toward the centre so a replacement was needed, that meant two new spars, as my local hs didn't have the required thickness and strength of balsa needed for the job, spruce and balsa laminations were made. local hobby guy gave me half price on the spruce and balsa too after seeing the part.

Next, onto the ribs, it looks like the ribs were die cut in different factories as two sheets had ribs that were 3mm short so 4 new ones were cut. another sheet went from hard to soft balsa so the back 3rd of two ribs were soft and crunched around the edges, so another two ribs were made. Another rib sheet had one rib that was a different grain to the rest of the sheet.

not expensive to sort out and sure fixable, but frustrating, for nearly 200dollars without wheelsand other bits and bobs before covering you know why people go arf.

fuse half built along with tail feathers and happy with that.

Yes, it doesn't sound ideal. I don't mind sourcing my own parts when going off-piste (e.g. adding a rudder to a 3 channel plane) but having to replace bits offered as fit for purpose is a tad annoying. Especially, as you say, when it was $200.

I thought die-stamped parts went out with 35Mhz sets

Not good though, if the parts aren't the right size and aren't built from suitable material you're having to buy your own balsa and cut your own parts (you can't even use the incorrectly cut parts as templates). You may as well just get a plan!

Not very useful if you don't tell us what kit it issmiley I can give you a bad one, a mediocre one, and a good one, but you have not asked, so I won't smiley

kit is by SIG and is the 1/6th scale J3 Cub. there is a disclaimer printed in the centre of the plan explaining that balsa wood quality is not as good as years ago because of high demand, I really believe that.

I read somewhere about extensive use of balsa commercially - I think it might have been for wind turbine blades.

Actually, I'm fairly certain that since the widespread adoption of this "green" power source, the wind has increased beyond all reasonable expectation...I wonder whether they've been wired incorrectly and are producing wind, not harnessing it? This would fit in with the general term "wind farm" - after all, an arable farm produces crops, dairy farms produce milk, livestock farms produce meat etc.

Martin, I thought it was the trees swinging back an forth that caused the wind, i have noticed that seems to happen a lot.smile p

Good point BBC - probably what causes the normal breezes - I've often wondered where they came from before wind turbines were invented...

While you're at it, could you enlighten me how stuff stayed on the ground before Sir Isaac Newton invented gravity?  There again, living down under it's probably irrelevant to you anyway as the blood must rush to your head unless you're doing a handstand!

Lol at Martin! BBC it's obviously an antipodean thing from your neck of the woods(groan), as every time the 70ft eucalyptus in my garden swings about I can't fly.face 20

see Martin, Radge agrees with me, but I think youve got it wrong, if Sir Issac is correct with what goes up must come down, then Australia must be the top of the world as i went outside tossed a rock "up" notice the "up" into the air and it came back down so if Oz was upside down the rock would have kept going.party

Sorry mate - I`ve got a globe and you lot are definitely upside down. Even your songs say you're from a land down under...

I wonder how long we'll get away without the mods giving us a kicking for straying off topic!?!

I'm surprised. I have found Sig kits to be good.

And a message about wind turbines or whatever on the plan is hardly an excuse for tapered spars and rubbish die cutting, is it?

Mark,P2, I have found other Sig kits i have built to be good.

Sig Kadet junior- i think called seniorita now??

Sig four star.

Sig Wonder.

This J3 Cub kit must have been the Friday 4 o'clock job. but the build is coming along steady and nicely now i have aired my grievances.
