Fine tuning a SV27

[sunsation288]

Hi all , since me and my son have the same boat , i don`t know why is boat scream compare to mine , we have the same setup , Lipo shield from Dimension Engenering , Lipo 5000 20c , the only chance i have is when he put is 3 blade (the one coming with the Kit ) , and i put a 2 blade (grp-2317.45) , we can have fun , but is boat have more punch ,
what i done so far is
adjust the trim tab and Strut equal to is boat

Question
1- on the pistol control what is the purpose of D/R knob ?
2- my option is a data logger ?

Sorry for my bad english , if i am not clear , feel free to ask
Regards
Christian

Ok what i have found for the D/R knob is adjustable steering rate ? that made sense ?

Yes, D/R control the amount of steering that you have.
Have you tried taking your sons prop and puting it on your boat, put your prop on his. Is yours now faster than his? It could be the difference in props? A 3 blade prop may work well at one strut angle and height, where as a 2 blade may not work at that exact setting. Usually you have to do a little bit of adjusting to everything, at least I have found, when going from a 2 blade to a 3 blade...??? Just my thoughts though. Try changing the props between the 2 boats first. Let us know what you find. How are the temperatures compared between your boat and his??? According Kintecracing.com, your 45mm 2 blade should be faster but run your boat with hotter temperatures.

Also, be sure nothing is binding or sticking in your drive shaft. Be sure to leave some space between the front of the drive dog and strut. A flex shaft will wind up and tighten under a load. If you have the drive dog (piece the prop locks into) touching the strut, it surley is binding and will slow you down.

Hope this helps,
Scott

He are faster by little

Lets stay on the simpe page. Does your son have "his" set of batteries and you have "your" set? I know you are running the same 5000 20C. But have you tried all batteries in your boat?

Yes, be sure the motor is inline with the flex shaft. Be sure the flex is well greased. Loosen the motor shaft collet where the flex connects and be sure the flex spins freely inside the stuffing tube.

If all of that seems ok... maybe try switching the motor and esc between the two boats? But, do one at a time so if it is the motor or esc, you know which one it was.

We will get this figured out...

Can you post us some pictures of both boats? Inside and out?

Yes, if it needs to be epoxied or glued again, be sure it is aligned as perfect as you can get it.

Take some more pictures also of both boats.

Have you tried switching ESC's or motors? If you do, do one at a time so you know which made the difference, if it is one or the other.

Drambuie pictures look great!
