Thanks Mankster I will try that !
Think I will do some cutting out with the dremmel this week. As you say shave a bit of the upper lid round the conning tower and remover a bit of the inner lining.
I am glad you said that, I have only put the lead shot in the WTC, not externally yet. I think I have got about 1KG of lead to put in yet. I was planning on putting it in when I was on the water to ballast it properley.
I didnt know that about the 4 tanks though. I must admit after weighing the boat this weekend I did wonder about how much bouyancy they will have in relation to the weight. Looking forward to putting that in the water and removing it
And just another thought I have used a higher power battery, its not much heavyer, but I think some tweaking is going to be needed here
