sv27 my first run...few q's

[Goonboy2]

Thanks for the advice on CG settings. Can you translate 27% and30% into millimeters or inches from the transom? Thanks.

[leeuk]

well ive ordered a new cooling jacket and 2 new props,a cf42 and cf45 so shud have plenty of fun with these.

i have a question tho,do props wear down from normal use? i know full size boat props suffer wear but do the same things happen with rc versions?

[Goonboy2]

Yes, they do wear but they will chip, bend or break first. But be glad they do, better to break a prop than a transom.

siberianhusky,
Just did the math on the center of gravity question. Figuring the total length of the SV at 686mm (27") - 27% would be 185mm or 18.5cm or 7.3" from the transom AND 30% would be 206mm or 20.6cm or 8.1" from the transom. How does this match up to your positions?

I have 2 marks at 7 and 8", depending on water I'm between these two points, farther forward if it's rough, right back if it's mirror smooth.
Rudder tucked in tight to the transom, stinger at 0 degrees to the keel and trim tabs all the way up.
The carbon props are great for testing but don't last, just last weekend a kid had the entire carbon prop explode during a run, no hub, nothing left on the shaft!
Figure out which one you like then get a metal one.
Each boat is a little different, we have 4 around here that run regularly and all of them seem to need a little bit different setup. The only difference should be colour, sometimes we even end up running the same size and brand of battery yet there are still slight differences.

siberianhusky,
Please clarify
Are you suggesting that we pull the rudder in as far as it will come - like 85 degrees?
Are you suggesting that the trim tabs be bent up or stay level with the bottom of the hull?
Haven't tried your Octura 440/3 yet, that will be my next prop.

Yep pivot the rudder so the bottom is as close to the transom as possible, helps keep the nose planted in the turns. Not sure of the angle, never measured as it's as far as it can go.
My tabs are as high as they will go without bending them, the screw on the adjusters is just touching the tab to keep it from flexing.
turnfin straight up and down looking from the side. I don't have a turnfin on the port side, no need for me, I only make right turns around a course (real or imaginary depends if we feel like putting out the bouys). Late in the year we have some weed problems in out pond so anything that hangs down is a potential weed collector as well.
Sharpen both the rudder and the beveled side of the turn fin until they are knife sharp, the blunt factory edge is awful!

[Goonboy2]

Roger that. Turn fins and rudder and prop are razor sharp.
Currently I have turn fins at 90 degrees.
Have you ever tried the turn fin(s) in another position like 135 degrees or 180 (horizontal) or even more disengaged like 200 or 220 degrees?

I tried the rudder tucked under and didin't enjoy my boat as much, kind of like the boat skipping round the corners, and i'm not racing
its just for fun!

heres the link to a video my friend made for me of my sv27

Your boat looks like its going well mate! get another prop and it'll be even better... for sure!

[leeuk]

Ive got a cf40 2 blade to replace the stock one and a cf42 &45 on way from ose so cant wait to give those a try!

Turning Radius

I'm going to continue to post in this thread as I just bought a Supervee 27 (not the R) and am VERY new to FE boating as well. Here's hoping the thread isn't dead.
I got my Supervee Thursday, took it out for a spin and was VERY disappointed with the turning radius. leeuk posted a you tube video earlier in the thread (http://www.youtube.com/watch?v=9fyzM...layer_embedded) and I would have to say my turning radius is about 1/4 of his. When turning my boat with the remote the rudder only turns about half as much as you could turn it by manually moving it. Has anyone had similar issues? Am I doing something wrong, or do I have a wrong setting? The trim on the remote is set to even so I am at a loss. Any thoughts would be greatly appreciated.
Thanks
Brian

Did you adjust the d/r? On the tactic radio its to the right of the throttle and steering trim on the old fm radio its on the top by the antenna.

D/R, Turning Radius

Thanks. The manual didn't state what D/R was, and when I was originally messing around, I assumed it meant "Drive" and "Reverse" but since I heard the Supervee didn't have a reverse, I just left it. Out of water the rudder turns much more now. Can't wait to test it out. Thanks Diesel!

[Goonboy2]

Also, you might try these:
Take the connecting rod loose from the rudder and make sure everything moves with minimal force.
Move the pivot at the rudder to the outside hole.
Install a longer servo horn.
Adjust turn fins to less than 90 degrees down.
