Just as a matter of interest what is the TD5, and how much did you pay, I'm playing with idea of building my self a toy, and it would be nice to use the same base as my 110 defender, so that parts are interchange able, but all the TD5 Defenders, I've seen have been too much to buy then cut up :twisted:
As for choosing the project, I change my mind each day, I find it the best approach stops you getting board.
