Looks very nice Dan, good luck with the flights.  Search for "reverse S-hook" for a possible solution to your motor hook difficulties.  Several folks recommended these to me and I've become a convert.

Dan,

From another post, it seems you are using a hard ring on the front of the motor bound in place with thread.  A reverse "S"  hook doesn't work very well with this.  Better to pair the reverse "S" hook with a common rubber "O" ring.  For models the size of your Otter. A 3/32 X 1/4-3/8 inch "O" ring would work well.  Make it easier to handle the motor when hooking on the prop, and it will wind around the hook just like the motor.

Most hardware stores have them in quantity, they are very inexpensive.

Also, you need to use a winding tube.  Even if you do not wind the rubber hard, the motors will eventually fail and destroy all your careful work.

The Otter looks really great!

I will look for the o-rings tomorrow.  FYI for those looking for small split rings I found a package of 120 each 3/16" and 1/4" split rings in the jewelry craft section at a local Walmart for less than $3.00

OOPS!!

This is why you DO NOT test fly in a small back yard!!  I knew better but did it anyway as I was anxious to try out the trim tabs I had added to the tail feathers. They worked so well it went straighter and farther than expected until the table got in the way.

Thankfully the  wing popped off clean, (Hmm apparently the glue joint was not as good as I thought it was??) with no structural damage. A bit of glue and it's ready to go again.

No more test flights of outdoor models in the back yard!!

You are certainly turning out some very nice models Dan..... and nice to see the enthusiasm continues. 

I have long been curious about the term "back yard" which in some cases seems in America to embrace quite large area that we would call garden or a small yard.  But I think you do not go in for gardens like us limeys - with little flowers shrubs a lawn garden gnomes and goldfish?  All of which are very model aeroplane unfriendly.

Our backyard is about 30'x80'. On the edges are a couple of bushes, a charcoal grill/smoker, a couple of tables and a chain link fence closing off a 10'x30' space for growing vegetables. So not really big enough for much more than a moderately sized indoor model.

Handy size for maintenance - and about twice the size of some gardens here........ but for my part what ever the size of the area you choose to use it never seems big enough....  but at least you do not have a pond!
