Curious as to why you put the steering servo so far forward in a tunnel

[Greg Schweers]

I've built 2 VS1 and 1 Cobra. I haven't run the Cobra yet 'cause the lake is frozen. Personally, I think the servo should be mounted in the back because the CG on the VS1 is very critical; and the speed controller needs to be as far back as you can get it in the boat. My servo mount is held in with two 6/32 buttonhead screws. The mount is made out of 1/8" aluminum angle. I cut a slot for the servo, and mounted it to the side of the radio box. The radio box ends up being only less that 14" long. I also cut the top of the boat open to mount the radio box down low. The box starts out about 3-1/2" high and slopes down to 1-1/2" in the front. I haven't weighed the Cobra yet, but the VS1 is ready to run and weighs exactly 5 lbs. (that's with the 4S 5000 pack). All of these boats are set up with the UL motors. I know on the VS1 that if the CG is too far forward, the boat will nose steer coming out of the corners. I would post pictures, but I have too many problems trying to do it.

Mike,

I general, most do that to get the ESC in the back with short wiring. If you can manage both in the space available it would be ideal.

Greg what problems do you have posting pictures?

Mike,

I am getting frustrated with you bagging the Vision's ability to run as an FE tunnel. I am not starting any fights but I feel you need to point out the reson you had trouble. If the CoG is set right then you will have no trouble at all.
Set the CoG on a VS1 at 35+% and see how it goes...I am sure the Shaman will be the same.

Now, back to the Author, keep up the good work Cat-Boi

Cheers

Dude, take a chill pill .....

[Cat-Boi]

glad I missed this or am I?

thanks Kris! I started a build thread in the boat building section.

Go and build your boat. I will love to see the new paint job and hardware.

looks very nice , doesnt look like it has flat ride pads like the vs1, what kind of differecnce does flat or sharp edged have on a boat?

[Kris Flynn]

Steve,

There are some VERY interesting design elements on this hull which all work in to give you a smooth handeling hull which can take all the power I have thrown at it so far.

I can personally say this boat is good. I design and build my own tunnels (when I can be bothered) from ply. I am currently on my Gen 2 31" tunnel and it can take the punishment I have been throwing at the Vision, but the cornering on mine is still second to the Vision.

Hell, all hulls have bad points...take the Lynx, everyone who has seen them race knows they have issues in the corners when chasing other boats. But I guess that is the price you pay for what is probably the fastest 20 boat out there.

Anyway, Mike I respect what you were saying, I just wanted it clarified so everyone understands that it can be used as an alterative to the VS1

Cheers
Kris

I hate when people remove their posts.
