DICK OF THE DAY

Dick of the Day is Glen by blaming his first hydro DNF on being too lean, when he in fact simply ran out of fuel !

TECH NOTES

The following discussion on Hydro rear wings may be of interest. It is from the old Listbot archive database at Rcboat.com   Merv and Chris both have it and can query the database if anyone has a question they would like answered.

--------------------------------------------------------------------------------

I'm gettin ready to launch my first scale, when I had the hull primed with a sandable primer the shop lost one of my fins. My concern is if I set the boat up without the wing on the back will I have to set it up totally different when the wing is installed, I am assuming there is a considerable amout of drag with all the breakaway wing stories I've heard....

--------------------------------------------------------------------------------

Steve,

The rear wing on a hydroplane is there to "lift" the rear end

vs push the rear end down like on a car. This lifting will help keep the nose down at high speed and on windy days. Your setup will not drastically change. You will find that there is a fine line at top end, and every hull varys, your there then your gone. (up and over) The best advise I can give you is to make sure you have foam in the wings, and connect them with

breakaway nylon screws. If the boat you built had wings then you have to run with them. You dont see any current unlimiteds run without them do ya, no.... because they work !!

--------------------------------------------------------------------------------

Thanx Joe, Do you have any recommendations on setting the wing up in a manner that will make it easy to adjust. This was originally a Dumas kit that was modified to suit my needs but the wing is pretty much stock. Foam filled but stationary mounts with no adjustable features.

--------------------------------------------------------------------------------

Steve,

What I do is use the front hole as the pivot, and create a arc at the rear hole. What you want is the rear of the wing to be negative (down). Again, if you could lay your boat flat on a surface, assumed running attitude, the "0" or neutral position would be parallel with the surface the boat is on, mark it with a permanent marker for reference. Now make adjustments so that the rear of the wing can drop below "0", I wouldn’t think you would ever go more than 1/4", but try 0, 1/8, 1/4. Making any sense ??

--------------------------------------------------------------------------------

Makes good since, let me clearify a couple of things. In order to achieve the neutral position I would set the hull on a flat surface without a prop or prop over the edge and elevate the sponson pads in the front say 3/16-1/4" to simulate ride surface. At that point I need to get a baseline measurement from the wing front screw ( pivot point) being that they are the center line of the wing, and then start at an equal measurement on the rear adjustment and call that "0". Make a permanent mark for zero on the inside of the fin for "0" and then try different positions in say 1/8 increments moving the rear of the wing down to create lift.....right?

--------------------------------------------------------------------------------

Steve,

Keep the front sponsons on the same plane the strut lays on,

you may have to remove the skid fin and rudder (prop) to get a good profile. Also check while you have the hull in this position that the back of the sponson running surface is right at the rear edge, you dont want it resting on the sponsons a inch or two forward and a gap from that point back.

--------------------------------------------------------------------------------

Set the boat on a flat set up table that is level. Fine tune the boat flat on the table so it is running on the rear riding surfaces of the front sponsons and the strut and maybe rear edge of the rear sponsons. shimmed about an 1/8th-1/4" above the table depending on the strut depth. Now level the wing at zero

degrees. Remember your foam filled wing will float but it is fatter then some of the older dumas kit. The wing will have a bearing on prop load at speed and you have to get your balence point set up in regards to percent of afterplane behind the at speed riding surface, (A.S.R.S.).

--------------------------------------------------------------------------------
