Hi All,
Just trial fitted cheetah's main wing on carbon cheetah it is fully adjustable in angle of attack and also has adjustment for and aft to change the point of lift. The centre section will have a manually adjustable flap for additional lift, both outer sections will have automated flaps independently controlled.

Hi All,
At last we have some decent weather so i have been able to make some really goood progress.... exhaust tailpipes are now bonded in and cut to shape, just require a carbon fibre trim flange to finish them of. Wing supports have had a couple of coats of two-pack, water pickup is permanently fitted. Carbon nose cone has been ground to shape and is ready for bonding together. have also done a bit more lightning work.

I have to admit that I have not been paying attention to this thread for a few months, Peter. Awesome work! How's the OL running?

Thanks Jon and C_ Spray,
Outerlimits is going very well still dialling in changed the tabs for 380's which has made a huge improvement. Just in the process of changing the helm unit to make the steering much more direct, also fitting a high pressure relief valve in the steering pump to make the steering consistent in both directions, once sorted to my satisfaction i'm sure this is going to be a very quick little boat. As soon as i have time it will be getting my fly-by-wire steering system and steering wheel mounted throttle paddles. Also adding a vent tube to the cav plate to aid planing with a tall prop.

All The Best

Hi All,
Just finished the re-work of the bow thruster installed the new battery and variable speed controller, have used buzz bars for all connections, time consuming but much lighter and neater than conventional battery leads, also made and installed mounting brackets for the dry sump pumps and filters will be piping them up soon.

Hi All,
Picked up the front wing mounting plates from Simon at Oval Stainless these are water jetted alloy, i then routed a chamfer on all edges and then blended in with a dye grinder. The cross members are made from yacht rigging spreader bars with the back flange cut off then ground to an aero dynamic shape almost ready for welding, also made a pod for the rev counters from low density foam which Carbon Weasel are skinning for me i will then remove the foam from the inside.

Peter
