New Rudder and Water Pick-ups for EKOS...

[Team Jericho]

Thanks for the link Forescott, much appreciated! I am waiting for Venom to confirm the exact size of the stock cooling hoses on the EKOS before I order all parts for my cooling project. I am thinkinf of doing after after the I get the new paint job done this month.

Those props look good too. I am running now with the red Venom 3 blade machined props 36 mm. Who is Chuck? Maybe I could order those props machined and balanced by him one day...I have no cavitation problems but looks like those 2 bladed props might be even better?

Im gettin 55mph out of the feigao 9xl's(2612kv) on 4s, and a pair of cf-40's. But the prop hubs are wider than the drive dogs so I dont really like the fit. Wow, 55 looks insanely fast to me, 70mph must be soo close to blowover on that hull!

10XLs on 6S. And it ran great until I scuffed the hull. Then it completely lost its ride attitude and wants to ride way light and blow over. I discoverd this after I put it in the water, hit the throttles, got up to maybe 45 or 50 and she went over. Cracked the hull, fixed it and it took stinger adjustment to bring her back down.... and lost 2 mph... I havent been back out to test since.

Chuck is 'Egneg" on the forums... his last name backwards.

I have the venom 3-blades too. In both 32 and 36mm. They are excellent props. I just like the performance of a 2-blade prop better.

hmmmmm.... didnt realize eggneg was chucks last name backwards. Good eyes!

Stock coolong lines are 7/32 outside dia. I switched to 1/4 outside dia. They still fit over the stock fittings and i put a small ziptie over the connections for a little extra insurance.

Thanks for that info Forescott. Having big problems with my EKOS now and Venom not honouring the 90 warranty on their website, saying it is now 30 days and that they have not updated their website yet...see my other thread.

Ive read em all and been there already. Much happier now that Ive given up the stock electronics. I use my venom motors for paperweights!

Hi Igoresky...I am trying to find the best height for the stock water pick-up tubes. I am instaling a new set now and am worried about them being too high and not getting enough water into them, or too low and creating too much drag which will affect speed. How low do you have yours? In your picture is is hard to see and I would really appreciate knowing from your experience with your EKOS. Thanks again for any help, tips, and pics.

I lowered mine far enough down to where I had about 3/8 inch sticking above the top of the rudder bracket. I think the tubes are too high from the factory. Set your boat on a flat surface. let the tubes rest on the flat surface, then mark the tubes where they touch the rudder bracket. Then loower them another 1/4 inch.

water pickup.

I put them level with the bottom of the drives so they have water all the time,now they are the next size smaller than stock for less drag.Now I have a new problem,the boat is way too fast for anything but glass.I hit a small wake from a jet ski and did a 52mph submarine,lost the boat for 10 seconds then it bobed up.The hull is busted in two spots on the sponsons. 12" is the worst one.The Octura X442s are super fast.The motors draw 80amps for a fraction of a second and go down to the low 50s but I cant hold it wide open for more than a few seconds with any chop.I went through most of a battery set before I crashed bad and my highest temp was 118deg F and the average was 112.My peak amps were 112 when I went under water wide open.It is fun to watch your run on the data logger,I can see all my blow overs on the screen.I am pulling close to 28000rpm at my peak speeds.I was at 0 deg prop angle and I will try -5deg next time so it will not blow over so easy.What angle are you guys running.

Thanks. These are pics of my pick ups and new replacement ...the new rudder kit arrived and the pick-ups are even shorter than what was on the boat! Venom are going to send a replacement kit for the replacement when they have them in stock again...with the new pick-up tubes, there is no chance they would even be long enough to rest on the a flat surface, never mind another 1/4 inch. So basically these tubes should be a bit below the lowest level of the sponsons, right?

[Team Jericho]

I am running my drives at - 2 but am still at lower speeds with stock motors and the red Venom 36 mm machined props.

Yes you want them low,at prop shaft level.Just go to the hobby store and bring your brass tube with and buy a smaller one and put it inside your stock one with solder or epoxy and set them level to whatever height you want to try.I have 4 exit fittings out my hull and the water squirts out a long way out all 4.Bad news I wrecked my hull,looks like I almost ripped off one of the sponsons in my hunt for red october!!! Now I have to get another hull,I wonder if the HOTR cat hulls are made better or if they are just a unpainted version of the EKOS hull.
