why does my boat pull

[jlr3rd1]

ok when running a left hand prop, at full throttle the boat PULLS HARD to the right? so when using a right hand prop , the boat want s to go HARD to the left x/440 prop??? after about 30 feet it will spin out if you dont let off the throttle, any ideals?? running a cf 45 right hand prop and 7 cell s 8.4 electrifly 3600 nimh batts?

Does it pull too hard to adjust the steering trim on the remote control?

[domwilson]

Where are your batteries placed? Do you have a smaller prop to test with? Do you have any pics of your setup?

[jlr3rd1]

YES when it turns it turns!!!!! i mean you cant do anything??

[jlr3rd1]

sorry here is pic s of the batt.s , plus i also have a 3 ounce weight in front of the motor as well as the 4 cell pack thats runs the bec?? and no other props yet

[Raydee]

Nevermind, I see that it is a carbon prop.

[jlr3rd1]

really , no none of them have been? with metal props the same??

[Raydee]

Is that prop all beat and nicked up??

[domwilson]

Is the stinger flat? It looks angled downward. On my own SV27 it like to run with 0 degrees angle.

[jlr3rd1]

no nicks ?? stinger , are you talking bout the shaft the prop mounts to??? if so looks angled down to me to??? would that cause the pulling??

[domwilson]

That is the blue shaft that the prop shaft runs thru. With it angled down that would cause the boat to run wet. Considering the other factors, such as the weight added to the front and the batteries moved forward, it may be a problem. I don't know for sure if it would cause the steering issue, but it is a start. Try raising it till it is flat with the bottom of the boat. See if that helps.

[domwilson]

Try bending those trim tabs so they are flat with the bottom of the boat. They look angled down too far also.

[jlr3rd1]

ok awesome:) thanks for the help , i need all the help i can get lol. i will make adjustments and try again and again!!! thanks again and will let you all what happens also removed the 3 ounce weight???

[domwilson]

Try it first with the weight. If it is ok with you, leave it in. If it runs too wet take it out. Play with the battery locations as well. It may help you some as well.

[jlr3rd1]

ok will do that and see what happens:)

Trim tabs..One may be set abit to far down than the other ?

[jlr3rd1]

well after moving things around the boat got faster, but still wanted to TURN?? so i looked at the steering servo and the steering arm was at 1 oclock and not 3 oclock?? but changed that and the boat is running great:)) thks for all of your alls help:) now back to my poor blackjack 26

[domwilson]

Do you have pics of the new configuration?

[jlr3rd1]

yes here are some pic.s:) running the 6 cell dtx 3800 the boat runs fine, when running the 7 cell 3600 s at top end the boat gets chopie and lose ???

[domwilson]

Can't see the pics. Might be able to help with that too.

[jlr3rd1]

sorry will try again?

[domwilson]

Is that strut flat? It still looks angled down. Also adjust the angle of the rudder. Make sure the bottom is pointed straight down. Where are your batteries placed? Try moving them forward 1/2" forward of stock. What prop is that?

[jlr3rd1]

ok will make changes , and headed back to pond:)

Especially post #7. Darin knows what he's talking about.

[domwilson]

Get some video. Would love to see how it runs now.

[electrick]

In one photo, your turn fin also looks like it's got a permanent right turn bent into it, but it may just be the camera angle.

Make sure the turn fin is parallel with the boat's fore/aft centerline when looking at it square on from the rear.

[jlr3rd1]

[domwilson]

Well, How dild it run?

[jlr3rd1]

[domwilson]
