Would that be a fat pig or a wild pig?

I built a yellow jacket last winter, it needs less wing incidence than the drawing shows and then it flies great.

More images in a little build thread here (non-english though); Yellow Jacket build

Nice work Kris. That's a good looking plane. Is that an .051?

That can happen to any of the engines if you rewind the spring too far. The spring is only meant to give you an extra snappy turnover, that's all. You should only rewind about 1/2-3/4 of a turn, any more than that and you'll deform the starter spring and it then hits the back of the prop when the engine runs.

As above .. over winding destroys both the spring and the prop.
No choice but to buy new ones of each, or at least a fresh prop and practice your finger powered prop flipping technique.

Or, you can try carefully bending the part of the spring that engages the prop back. It will probably end up on top of the rest of the spring, but I have done it.

Worth a try before you pay $5 for a new one. You might find you don't need one at all.

I like your avatar Matt. What kind of plane is that? Looks like a bitch to learn to fly.

Here's my old battle axe with a new Killer Bee hiding in it:

That would be a GeeBee (GB) Model R2. My favorite plane next to the Piper Super Cub. Yes, they fly, take off, and land very fast. It did break a record or two. Has a big Pratt and Whitney 9 cylinder radial.

"GB" stands for Granville Brothers, the designers.

Some good info here -
