Proboat Elam windin up

[Jesse J]

Well here is a fun little compilation I put together of a couple sessions. Sorry no music, but hopefully some style that will compensate.... Unfortunately the vid card filled up JUST before the nose dive - total submersion for 1.7 seconds and resurfacing, but oh well, who doesn't have a big fish tale?

This is one of three spec class hydros I am prepping for family racing. Converted from (I don't know why) nitro set ups. Proboat motors on 5 and 6S. Gotta thank my buddy JP for photography and filming (not professional grade camera like CAMEL though).

Wolf, this is your competition!!! I will have a clone of this in Llumar yellow when we rumble at new years!!!

Nice job, thats definately a tight fit in this hull. Was she a converted nitro or electric Elam?

[Jesse J]

converted from a unsoiled nitro set up. Yes tight is an understatement!!

I am going to have to realize how much hell you give this stuff. :)

If you want to replace the bearings when they go then I suggest ceramic.

Looks good man.

If temps were good I would bump that prop up and gain another 4-5 mph.

[Ub Hauled]

She fast man!
Very stable as well!!!

Has anyone seen videos of Darin's Elam? I wonder how hat boat is doing.

[Jeff Wohlt]

Jesse, your 093 drives are done and the Etti is ready to ship. Not sure what I can do with that other coupler with the set screw broken. I can try to drill it but doubt it will work. I use larger set screws now in everything.

[sailr]

Dang Jesse, you can sure cram 10 lbs in a 5 lb bag!!

[Jesse J]

Sounds like a plan Jeff, don't worry about that coupler, I just sent it along in case it was an easy fix. I am glad you use bigger screws cuz that guy broke my smaller hex.

as for the hell I am giving your drives ------ I can't hold back!! my 27" 5S cat is routinely breaking 1/16" drives on a M440 (surprised?) but the weird thing is that they break in the middle??? I have a continuous smooth curve in the stuffing tube, but after a little bit going that crazy they pop. I will send you the two drives so you can assess and in the mean time, I retrofit her with 5/32 stuffing for .078. If it would help I can send you some pics of the bend, which I thought was pretty graceful, but the break is not so...

Back to the Elam, since I am working on the prototype for my spec class Proboat hydroplane racing fleet, are you thinking that the bearings won't be able to handle 30K rpms? remember these are Proboat 1500 KV motors on 6S -- not eve 35K rpms. In my next couple struts I will be ordering before long, are you suggesting ceramic bearings? If so I will be then getting 3 sets and move this one to the cat.

[Jeff Wohlt]

If they are breaking in the middle then sounds like rubbing on the stuffing tube...look where they break and see if they are shiney.

I am just sayig on the bearings you may want to step up. I only use meduim grade bearings. The full SS or ceramic can handle more. Ceramic are excellent but still need the lube. I fill my strut up before running them after the shaft is installed.

On 5-6S I really would stay with 78 wire. You should check other before the break to see if the rub is eating them....but it should eat you stuffing tube first as carbon steel is pretty darn hard.

Jesse, this little girl is pist on 6's!!!!! You did a really gooood job on her! Ive got another set up in the mail right now. You will smoke me with your 6's set up! Watch for some upcoming testing on the elam...

[nate]

Hey Jesse What packs or pack was you running, and also Im guessing this things in the mid 50's she's flying!! Can you get some pictures of this boats insides? Thanks

[nate]

haha nevermind I didn't watch the rest of the vid, I c now lol

[Jesse J]

Nate, I was hoping to run those 5S packs you sold me in this set up, they are GREAT packs, by the way. This was on Rhino packs ($60 in batteries...).

I am workin on the Oberto now (my new avatar), she's another 50 mph demon but on 4S. Vids to come shortly.

[6S HYDRO]

i think you didnt hold it long enough, need a bigger lake. that looks like it would have gone faster than 47mph,
i did 53.1 on a totally stock ul-1 on 5s, with a 38/63L prop and yours looked and sounded faster

[Jesse J]

Good observation Paul! She was twitchen to open up, but I was not used to a waterborne missile. I have a pond now that should be big enough. I will try to get out Sunday to try the Elam and the Oberto - as long as the weather holds and no wild wind.
