Ha Ha I did not think there was that much foam exposed 
Anyway it stopped eating it, but the resin was still sticky this morning ( had this sticky problem last time I used it, that's why I stopped and stayed on epoxy ) so I took it out into the sun
But did no modelling today as it was to cold out of the sun, so I did a bit more of my pebble ( that we pick off the beach ) wall
So in the morning I will buy another box of poly filler
Hi Simon the legs are rated at 12kg, this is a cheap jet build, retracts in my opinion are way to expensive

Electrickery is the work of the devil.

Far better to start again using the correct materials.

OR glue on some 3/5 mm Depron on the bare patches and sand to blend and use light weight filler to finally blend in
Anything will fly given enough power

Only polyurethane foam is safe with polyester resin. It used as the core in surf board.

Correct materials ? the problem started because I cannot get the blue foam, inexperience with what im doing led to the second problem
It will come good in the end I believe, it is the first one so im learning, that's my excuse anyway

Again today it has been to cold outside and in the hanger
So all I have done is slapped another coat of filler all over it
When it drys I think I can then start to finish the plug

Got it sanded down today 
It came out ok so now im up and running with it
I put another coat of filler on it so hopefully I can sand it again tomorrow and fill it again
Sand and fill until its good enough ( in my eyes )
Now im off to bed as I don't feel to good at all

Sanded it down again today and it is coming together, but still getting some problems with this foam
so I dug out the remaining offending places and filled the in, will sand them off tomorrow then it will be ready for glassing
Did some drawing of the wings tonight but it was to cold to stay out there

Sanded it down again this afternoon, then tonight I laid on the first layer of fibre glass cloth and resin
When its cured I will sand it down then put a second layer on
