Sounds like a lot of technical stuff there Silky

, a lot of fun but bags of skill needed,the young fellows got a Nitro rally car each something similar to Daves for Christmas 0ne year & joined the local club etc & used large car parks [LARGE CAR PARKS] to practice on, but after a few months the notion soon wore off after large maintenance repairs + parts, tried it me self, lighting speed plenty of fun but it was hard with a lot of years experience needed,keep at it though.
