£242 is a good price but it'll be nearer £300 when you have bought the rest of the stuff.
I Don't know about the pipe but its probably better than the standard one I use a 086 which is cool. There are loads of servos about but the sanwa (airtronics) ERG series are highly recommended. I just use a JR 577 at the moment which is adequate but not awe inspiring. On the engines I have an OS RG.21 but the TQ will use the hyper 4 port and the PBS the hyper 8 port. I recommend doing a search on here and look at tuning, as some people have tuning issues with the 8 port. the PBS has adjustable steering and a laydown servo for lower C of G. the steering isn't an issue for me because the TQs C-hub is more accurate than the more adjustable PBS. and the gravity issue won't affect you if you're bashing.
Choice is yours bro
