Well had it out for the first run today. All I can say is WOW It is a new boat. Launched with no problem first time set the needle and the relaunch perfect. Runs up on shore have to get use to the boat gliding so nice, Real light on its feet need to lower the strut. It rides out of the water like a plain flying just above the water. Tried every prop I had in the box at the time H7 no problem. Went threw the lily pads and picked up a large piece of it on the boom tube and it didn't care. Throttles real good comes from off pipe to on pipe with ease.

Haven't leaned it down all the way yet still running the same plug 5 tanks a first for me.

Will let it all hang out tomorrow. Will see what shes got.

The shingles make a difference but the tunnel shingles make a larger difference. Just make sure that you keep all of the shingles VERY sharp. Good work David.

Thanks Charles

Will be racing it at Tampa race next weekend. Will see if it works in race water. It is a little lite on the sponsons with 3.8 and 4 Deg AOT. Will try some adjustments this weekend to tighten it up. Hooks a little with the turn fin set forward. Dose not need all the leverage to turn now.

Usually the normal AOT ( about 3 degrees) is all that is needed on the sponsons as the shingles, due to there design, have a much steeper AOT but for only a short distance.

With the ledges on the sponsons, made up of the shingles and pad, some time a slightly larger or deeper(I prefer it deeper in heat race water) turn fin is required to prevent the boat from sliding out in the turns and catching on these edges.

Good luck with your boat.

I was out today testing. The water was real rough 2 to 4" 10 to 15 MPH wind. Yes it dose catch a edge and it is harder to keep the fin in the water. Running the top of the sponsons flat. Will try to give it some nose down to keep it in the water and lower the AOA. I can see the longer fin will help.

The boat will pull all the prop I have H7. Pinched it way up with pliers and just keep getting it. Right now I am chasing the setup every time the speed goes up. Will run the H5 at the race to keep the speed down till I catch up with the setup.

I have found that with the carbon tube booms if I put a solid carbon rod all the way threw the boom. It will bite better it calm water but in rough with the rod only in the mid section it runs better in the rough. With different inserts in the tube you can tune the tubes like shocks on a car.

Will save more testing till after the race.

You might find the airtrap works best on calmer water. In 4" chop your boat is in the air most of the time anyway. Maybe a narrower airtrap & sponson? Removable ride pads would be cool for testing.

With the plain ride pads yes, with the shingled ride pads they really like rough water.

As far as the sponson boom tubes, I make them a rigid as I can and make the adjustments elsewhere.

Charles
Got the boat home and found both boom tubes broken at the mounting screws. It was h$!! on the water Sunday.

Got new ones on and will give it a spin this week. Going to try spinning a cut down 1650

Heck if it pulled the H7 with two broken tubes who knows?

I guess I will find out.

Going to put shingles on the rear sponson next.

Was out flying the rigger again today. Wish I could get a test with out 15 MPH winds. The boat will fly just over the water for 2 to 3 feet no roster tail. It runs strait and level no hop on reentry. It is the craziest thing I ever saw. Just can't lean it out to much or it will hurt the plug. In the rough it's like flying a plane. Made a longer fin and it is much better also moved it back not as twitchy real smooth now. Nosed down the sponsons .5 deg no bounce in the front now. Maybe tomorrow will be better test day.

Have a AB CNC 5082/3 to try.

Be careful with that AB prop. I've got a 3-blade that turned itself into a 2-blade on a Cat.

I run a 5077/3 on my cal craft. So far so good. I clean up the hub where the tool cuts are and it seams to help.

I tried to run this prop on the mono but it has to little of a blade area to move it.
