i know everyone is sick to death of blackjacks but it's what i got. i'm running an iv bag(no bubbles), i'll run it for about 4 mins and then it slowly dies. the engine gets quite hot but theres water coming out the outlets. (it also has a full mod motor in it). also i ran 3 different props on it and got consistently 48.and change mph. i had an x472,x572,and an x470/3, all the props let the motor wind up. i'm assuming that is my hulls limit. any ideas.

I have one done up with every mod. No clutch, 1/4'' shaft all the way, dual aluminum rudder setups, relocated tape on lid radio box set down between rails, gas bag down low next to engine, 1/4 scale steering servo, full mod engine, complete new 2" band pipe setup with water cooled flange and 3" header. It was doing about the same speed 48-50 on a really good run with the X572. Any faster and she'd blow over unless you set it wetter but then it wouldn't do 48 any more so I guess that is about the speed limit for that hull maxxed out.

Thanks Daniel

are you still running a single waterline thru the head and does it run hot?

Black,
when you say the engine is hot, how hot is it?

do you have a temp gun?

Dan.

No, I have two dual pickup rudders for a total of 4, No clutch, no pumps. I am only using two though one for the cylinder one for the exhaust flange and pipe.
It runs very cool. Are you still running the water pumps?

no,i ditched the clutch,water pump,3/16" cable,throttle setup,hard tank,and went with aeromarine rudders.the head gets to hot to touch.i don't have a temp gun.and i still can't figure why it dies after a couple of laps.
