Building this up at the moment, still needs finishing/cleaning up before I fit it to the hull.
Uprights are 3mm hardened alloy plate and the brackets are 3mm as well, the rudders are 1.5mm.
All materials were sourced for free so thats a bonus, hoping to have it finished up by next week.

Got some more done, self modded high flow muffler box, not shiney and new but not too bad for a home job and a blower fuel tank fit perfectly between the uprights and mounted nicely behind the engine not blocking too much extra air flow. :D

Also made this nice alloy arm to connect the carby to the control rod for the throttle servo. I wanted to be able to remove the whole engine stand complete to put it on another hull if I decide to build a new one and keep it as simple to hook up as possible. 8)

New, simple watertight container for the radio box to replace the old plastic container with rubber bands holding the lid on.

Really all thats left is to mount the prop hoop, charge the batteries and fuel it up for its first run in a fair while.

First time back out, still need to do some tuning yet.

Cheers Doug, it really is a blast to drive (like drifting) and good for the kids as it doesnt matter if they run out of water cause there isnt anything to break (ie. prop/strut/rudder)

A couple of pics. as it sits now, I havent put the prop guard back on yet as it seems to be balanced just right at the moment.
Could use another paint but it has seen plenty of use and I might build a slightly smaller/lighter hull to replace this one yet.

Looks really good, but I'd get a prop guard on it if it were me. Doug

definitely needs the prop guard

very nice model, also need a seat with a pilot on it.

i bet this thing can realy move when run in a straight line
