Budget intended conversion

[gogglespaesano]

If you already have the st-rr, I would keep that rather than selling it and getting a roller of ebay. Just sell off the nitro stuff you aren't going to use and put that toward your conversion. If you buy a roller, you never really know what you're getting until you get it.

Arct1k is definitely trying to help you out by keeping you from making a mistake a lot of us have made and you'll find that BrianG is one of the electronics gurus on this site, definitely someone to listen to.

Good luck and post up pics of your conversion when it's done!
