revolt 30 leopard build..

[Cinnabun]

So I had a revolt 30 and got bored with the speed so I decided to build one of mine up, and leave the other one stock.

Leopard 3674 and 180a speedo.


Dual water pickup installed


So I take the boat out. I ripped for about a minute.. than lost forward power... boat drifted back and found out the flex shaft broke at the prop shaft and submarined my fresh m445. Removed the remaining part of flex, and found this..



So I hopped on ose and ordered an hd flex cable for a proboat Impulse. Its a .187 flex with a 3/16" prop shaft. Also came with attached drive dog, and the fancy prop nuts. I had to cut the flex approximately 1/2" to match the stock length and removed the teflon liner.



And heres a shot with the flex installed, with an x445 prop.

More pics with the water cooling is finished.

and a shot of the water outlets


Next plans are to line the inside with carbon fiber, and put a carbon fiber battery tray in

Very nice! I like the dual water outlet! Question: How did you mount the transom pickup? did you use the existing hole on the strut bracket? If so, how can the transom pickup do double duty to hold the bracket tight against the transom? Just want to learn!

[Cinnabun]

The transom pickup has a bolt from the inside and uses the factory strut mount bolt hole. The stock strut mount bolts were a larger diameter, so I was able to remove the stock bolt and put the pickup bolt through the metal support on the transom and it clamps the strut. Backwards from how the bolt would go from the factory, the head of the bolt is on the inside.

I got the idea from dirtsnowrider. His revolt was a huge inspiration for my dual water cooling project.

Thanks, Looks real nice, post some video if you have a chance!
happy Boating!

[Cinnabun]

I will try to get video asap. It should run pretty good.

The existing outlet hole was used for the second inlet, also. The motor is connected to the transom pickup because the flow from the rudder is not constant I feel. When making a left turn, I find it hard to believe that the rudder is still picking up water. And I believe my motor will be the main source of heat in my setup. If this proves incorrect ill switch the flow so the esc gets the transom pickup.

[Mike Caruso]

I think (not sure) the ESC needs the better cooling than the motor and the way it looks is the rudder is cooling the ESC. Caution I have run into a heat increase problem when I add left trim to the rudder. When I am spinning a big prop trying to make the boat run straight without shimming the strut. It reduces the water to the rudder pickup hole and does the same for big left hand turns. I would simply switch your hoses an cool the ESC from the transom water pickup which is a nice idea BTW. Since I have moved my water pickup to the bottom of the rudder.
My 2 cents

[Cinnabun]

I was thinking the motor would produce the most heat. Ill run it and check temps, than adjust lines as needed.

Im looking for 50mph with the x445. I will be happy with that.

[tlandauer]

I am not familiar with this boat, did you enlarge the pick up hole on the rudder, I seem to recall that was one of the notice AC put out. I have a Pursuit with only a rudder picket, seems to work.
Your first run take a very close look at the temp and you should be good.

[Cinnabun]

Mine is a gen 2 with the revised pickup. That notice was for gen 1 revolts if I remember correctly. Im really not a fan of the revolts rudder pickup.. it seems to me if its running dry enough the rudder pickup would be at the water surface

[tlandauer]

Well, with the dual pickup you have either choice, I think it's going to be great! This is a funny hobby, most of my boats are in a "down time" right now, I got rid of the bounces on my MG, but I had to re-bend the stuffing tube for a more negative angle, haven't had time to try that out yet. Couple of other boats needs some improvement as I am learning more, I want to do it the right way. So I am flying my heli to get the rush. lol...

[Cinnabun]

Lol.

Today I worked the m545 and got halfway through polishing it. Thinned it quite a bit, sharpened and balanced it.

[tlandauer]

that is still beyond me. may be one day...

[Cinnabun]

Its not hard once you understand what youre doing.. I screwed up about 5 props trying different ways to cut them. I can do a 2 blade prop in about 2 hours by hand. The m545 took about 3 hours to get where it is, the prop was very thick. I have about a half hour of polishing left and itll be ready to run

[Mike Caruso]

That's the only prop that does not run good on my all stock Revolt. I did like you thinned as it was tug boat prop. Put it on my friends AQ27VR with Revolt ESC and it runs mid 40's and very stable smooth. The Revolt hull is longer only on the front and has the motor in the rear and the 27VR is the same hull just shorter and has the motor more forward that the Revolt. But it loves the M-545 and the M-645 LOL Drive cable length Revolt 8.00", 27VR is 12.00" motor is 4.00" farther forward.

[Cinnabun]

Thats odd. Mine ran great with the x445 all stock. If the m545 doesnt run good I have a detongued 642 sitting here

[Mike Caruso]

Never tried X-445 I have to S&B one I have here, M-545 ran fast but tail wag bad at top end. Yours should like the detongued X-642. Was at Hobart, IN yesterday great race only once a year need some Fast Electrics to show up.

[Cinnabun]

The x445 is the best running prop I have for my stock revolt. Im going to test the leopard revolt with the m545 today and see where Im at. I plan on raising the strut a few mm to get some hull in the water.

[Mike Caruso]

Have fun today. I did all my prop testing at .400" hull bottom to center line of tube and Zero angle no +/-.

[Cinnabun]

Thats about where mine is, however when I first ran the red revolt with the leopard with the m445 it was way too aired out and blew over when I got close to 3/4 throttle.

[Mike Caruso]

Nice just right LOL

[Cinnabun]

Lol yeah man she was running very good until it snapped the prop shaft. I think the .187 cable is gonna take care of that though

[Cinnabun]

Ran it again today.. didnt end well. The leopard is just way too powerful for this hull. With a neutral strut setting and 0* thrust angle, the bow is raising way too much and causing a blow over. It's about as fast as my stock revolt at 1/2 throttle, and if I try to pull full throttle the hull jumps out of the water and it goes crazy. Im going to raise the strut and drop the trim tabs a little bit and try again, also going to prop down. The m545 had way too much bite and threw the hull around like a rag doll.

[Mike Caruso]

WOW gee wiz I would take take motor out and send to me !

Maybe a 445?

[Cinnabun]

Im going with a stock 42/55 grim and go up from there lol

Also forgot to mention that I ran 2 heavy 8000mah 2 cells to the front of the battery tray

[Mike Caruso]

Good idea sounds like fun.

[Cinnabun]

Its tons of fun. Lol.. today it flipped so bad it was in the air and blew to shore

[Mike Caruso]

BAH as long As it's ok

[Cinnabun]

Some slight nose damage, it should be repairable.

[Mike Caruso]

My Revolt is just fine @ 48-52 mph not racing just fun. I am going to buy a ETTI 29" http://www.etti.com.hk/product_info....roducts_id=336 with self-righting must have.
