Footprints

[Grimracer]

Hydro racers,

Some time ago I stared a drawing called “FootPrints”. It’s a database of hydroplanes and placement of parts and setups.

It might be fun to collect more of this data..

Lets stick with outriggers for now.. Having said this I do have a Sport Hydro database as well.

If you want provide me the following and I will post the info here for all to share and ponder.

If you feel it might be a bad idea to share your setups that’s OK.. this is merely to stimulate conversation and not to STEEL anybody’s knowledge.

OK.. for those of you that want to participate.

I need..

1. Type of boat (FE-Nitro-Gas and name)

2. Distance from back of the drive dog to the back of the sponsons.. if they are different provide me that as well.

3. Distance from the back of the right sponson to the furthest back point of the turn fin

4. Distance left and right from the drive dog to the sponson keelsons

5. CG measured from the back of the sponsons rearward

I know what your thinking.. There is so much more.. True and we can add that in the future.. for now lets keep it simple.

When we start getting info I will post pics as we go.

Maybe adding rudder offset and distance (back edge) from drive dog would be good.. we could then include an angle from TF to rudder.....

here are specs on my eagle .21 rigger, grim

1: nitro eagle (pre sg or sgx) .21 rigger

2: left - 18 3/8"

right - 18 1/4"

3: 2 15/16"

4: left - 5 13/16"

right - 4 5/8"

rudder offset (from drive line): 1 15/16"

rudder trailing edge behind dd: 3/8"

a few words about this boat. i have not set it up, so cg is unknown. sponson tubes slide in & out, assembled to the most obvious wear marks. drive line is offset in tub, rudder is on the LEFT.

tub width: 4 3/8"

drive line offset (from right side of tub): 1 13/16"
