Screwed to a larger piece of 1mm ply glued on the foam I reckon that would be fine.
Depend on how heavy the model as to how strong the hook needs to be
This is what I started with and it failed by splitting the wood where the pin is, if I bound the timber with cotton around where the pin is fitted in before I epoxied it on it whould have been just fine. you can see the 1mm ply I used to spread the load.
to give you an idea my flying wing weighs 1.25Kg ready for launch
That hook was also right on the C of G I shifted about 2 3/4" forward this time
