This Geico rc-model is really cool, but as a (pro?) model racer, I`ll have to warn you guys; THIS IS NOT A TOY! Not even for you who races the 1/1 scale racers! To build something like this (and don`t waste your money on a project that will end in the garage), you should have lots of experience & skills from easier rc boats first.
I just say this because I`ve seen "rich guys" buy the best and most expence equiptment before without any skills, only to realize they could`nt get it right.
This is not a rc model you just throw on the water and run to have fun with your kids... This is just as hardcore as the real thing...
If you want a cool rc-racer, there`s lots of great projects to start with that`s a lot easier, but have just as much "cool"-effect as a turbine model. MHZ makes a great Skater 399 (just like Nigel`s) where you can put in twin staggered Zenoah, RCMK or CMB 26 ccm`s, with Merc. #6`s, Arnesons, Trimax or whatever drives you want.
Aeromarne Laminates makes a great looking (and fast, if you build it right) Donzi 38 ZR Comp.
Just my .10, but I really LOVE THE TURBINE GEICO MODEL!!!
