we do not build RTR's but someone like Ross madina from full throttle racing could pick the hull up from us and build it. without a shipping charge to him. look at our thread here on rcu about expresscraft boat hulls. Ross has a great reputation and does nice work. I would do the 84" hull for 750.00 with carbon fiber. we also have doug from [email protected] that is also local and does fantastic paint work.All I would do is the hull after that is would be between you guys but both of these guys have been doing boats for years.
