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

[forescott]

Adjust your COG and you should be able to get it to handle great. As stated before, Im tenths under 70 on an identical hull design and have no handling problems what so ever.

This run the GPS did not record. the next days run w/ no adjustments except repositioning of the GPS showed 66.7. Stock 442 props, only sharpened and balanced. Again, 10XLs on 6S.

Bunch of Algae in the pond so I could run much past (to the right) of where I was standin.. but you get the idea. This was also its 2nd run ever.

And heres a pic of her complete.

Not trying to jack the thread w/ a HOTR hull, but they are the same design and just commenting on how they can and will run way past 50. They (EKOS, HOTR and Skunk2) are all a fantastic hull design.

I was wondering how you were gettin that kinda speed on this hull. Your batteries are much further forward than mine. I think I'll try moving mine up a bit to keep the nose down!

I think my cog is about 8.75

I just realized the 10xl on 6s is approx 52000 unloaded rpm. Is that right??

About 36600. They are 540 size 1658KV.. I think..., not 380s

[forescott]

AAAAH! ok!

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!

Here is a pic of the crummy fit of the cf-40 vs. the 442.

Nice!

I wonder just how much difference that will make. It should make some, any flat edge in the water is added drag.

I just hope the 442's wont burn my 9xl's!

Is the 442 made for the 4mm prop shaft? Or is it shimmed?

Also, did you sharpen them yourself?

I'm getting ready to order a pair and curious.

[forescott]

Its shimmed. Had the 442's prepped by chuck genge(egneg)

If they dont work out for me I'll send you a pm.

Please do!

Might try to taper that hubs down...easy to do with a file.

Your right lost a doggear and prop that u sent me but I think it was from a loose prop nut. But I'll screw every thing down make print and file where it was printed. Like that of the stock shafts but these are stronger lol and don't rust as easy. Pulled my one flex shaft out and it was or had started to rust.

Had the ekos out on the water today for a test run with de-toungued x442's on 3s. Hit 52.9mph on gps. Pretty fast for 3s but the motors were pretty hot after 2-minutes runtime. I think the 10xl's would fair better with these props.
