Issue with water pick up from rudder

[Mulisha]

Photo on left is the rudder i'm having issues with getting water in and by comparing it to the photo on the right im guessing it is because the inlet holes aren't tapered towards the leading edge of the rudder? (Ran for couple of mins before realized no water coming out of outlets not sure on damage to motors, not happy ... )

Throw that rudder away, it is not fixable because of the way it is drilled.

Can a dremel do anything? How the .... Can a Rc boat shop sell it?

I am sure the hobby shop would be glad to make it right. Probably no one noticed as you didn't until you had a problem.

I don't see why you can't fix this with a dremel. Rudder pickups really do work the best you can get this thing to work if you make a nice ridge in the aluminum.

Contact Joe at R/C Boat Bitz. He will make it right. As Egneg stated. He wouldn't have seen it either.
A little issue like that won't stop me from buying from there.

Definitely one that slipped by. The pick up holes are drilled before the blade area is milled. This looks like that step was missed so,ehow and then they drilled holes at a perpendicular angle to blade. This is not needing to be thrown away, just grind (dremell) a parallel path for the water. It's still worth sending back if not going to be using, I'm sure they will make it right.

The rudder pickup holes are always too small IMO I always open them up with a dremel. You should be able to grind some grooves and fix that.

Just disappointed to buy something that doesn't work the way it should. Sent email waiting for reply they closed Monday so hopefully tomorrow we can sort something out. Suck everything ran with no cooling things were but by the time realize there was no water coming from outlets

Yeah well sometimes these things happen. Stinks when you're the one, but it sounds like boatbitz will take care of it.

But the replacement blades are the same. I guess that's the way they are designed. Seems strange that they would manufacture & sell them if they didn't work. I hope the temps didn't get too high.

I'm a little confused to seeing every other ruder you see has the grooves to the leading edge. Got a response and joe has sold a fair few without issues so not sure why it doesn't work on mine, maybe different boats (mine the zonda twin cat) but anywho has offered to post new version when it gets in stock with grooves in it :D. Does the fact that this rudder has identical holes on both sides of the rudder have any effect + or -? The holes meet in the centre then run up the rudder to the water tubes

Temps weren't super hot will it have any ill effect on the motors getting that hot?

Only time will tell.

An entry hole on both sides isn't a issue. I've had blades with that arrangement. What might be an issue (& I'm talking about other makes of blade here) is that sometimes when they drill the holes down through the blade they exit the bottom of the blade & then plug the hole with a sealant of some sort. If the sealant is not there, then the water is sucked out through the bottom of the rudder. Have a check on that.
The other thing is that the holes down through the rudder might even be blocked. I assume you've checked that though. Can you blow through each nipple?
