Miss Geico-What Works For Me

That's a lot more then 1/16 of a difference which is where your your depth is going to be a lot different than mine. Plus the angle of the photo's are different which can add to a odd view.

Dale, stop looking at the top of the strut to the bracket. Im not talking about 1/16 from the bracket to the top of the strut. Yes, mine is significanly more than yours. Im taking about from the bottom of your boats transom where it meets the bottom of the tunnel, to the bottom of the bracket that holds the strut. They look about the same, your boat to mine.

But no matter where anything is mounted on the transom, if the bottom of your strut is on the table, while your sponsons are also on the table, (all three points sitting flat) then YOU are running HIGHER than I am in turn means your distance to the bottom of the hull should be LESS than mine. Right? Unless your picture is just very misleading. Mounts on transom, amount of strut above bracket has nothing to do w/ fixed points. Thats whats baffleing me. Again, looking at the pictures, looking at the strut on the table and the tails of your sponsons are on the table. Not anything else. Those 3 points are the key to setting up one boat to match exact to another... besides cog etc.

No clue man, You been lost me. Like I said maybe angle of the pic is throwing you off. Maybe you can draw a arrow to the spot your talking about. But I'm lost all I can say is boat on the bench sitting on the ride points that measurement is what I got. if I can't provide further information than that, let's move past this confusion.

You left a burnt smell coming from my brain, but your still my buddy

just set my geigo strut flat and level with spnsons scott...will test it out tomorrow with a friend that has his hauling in the vid i posted here

Ran mine in a race today and it was fantastic. 4 min offshore heat, 4S2P, Turnigy 120 ESC was 117 degrees. Motor was 102, Batteries were 97&99. I ended up hitting something somewhere around the 3rd or 4th lap (out of roughly 10ish) and launched and barell rolled the boat after coming out of a turn. She landed wet side down and I kept on the throttle, but noticed it handled a bit diffrently. When she came in, the nose cone had slipped out of the strut and the prop tagged something, whether it be the bracket or if I hit something in the water. Very minor ding in one blade that was straightened out in less then 2 minutes. I will have a video of the race tomorrow that another member took.

Hey guys, got a chance to run the Geico for the 3rd time today. Been following this thread for a bit and set it up using some of the suggestions here.

I put the boat on a flat table strut on the edge with the prop(x642) hanging off. I put the strut flat on the table in the neutral position. From the side view propshaft was slightly above the last pads.

Ran it like this with tenergy 25c 5200mah lipos all the way back on the trays. I have the stock inline rudder and had no bounce when going with the wind, into the wind there was a slight bounce. Thanks to everyone for the loads of info on setups.

Not sure when I will be able to test but will be trying out my grim 40x52x3 and a V940.

Here it was in Sundays race. I think I may have caught a line off the bouy and got into a chine walk thru the Titans wake when it barrelled. It definitely hit something as I said before with the prop damage and strut knocked back a bit.

Great run!!!

Boat looks awesome!

Does anyone know what the equivalent of the stock prop in metal would be? I want to keep it stock, but with a metal prop so it doesn't break. I dont want to start messing around with amp draw by going any bigger or changing the pitch.

Thanks in advance!

I cant remember what the stock equivelent is, but running 642s is the most common prop and no one has issues w/ it. Ive been running a 642 in my BJ26 w/ all stock electronics for over a year w/ no issues at all. However, I found the 640 to push the MG a couple mph faster....

The prop is essentially a Prather 215. The X642 is similar.

I find it very hard to believe that an X640 would have made the boat go faster. That wasn't my experience when testing. I'd suggest that this had more to do with strut position than prop change.

The X642 is a good prop to run on the stock setup if you want to be ginger with the electronics.

[JackBlack26]

Thanks for the response, Darin. I might just get both.

Not the first time Ive had smaller props produce more speed. There was no strut adjustment from one to the other. I spent countelss hours with the 642, adjusting height and strut anle. Threw on a 640 just to see and got 2 mph faster than any of my 642 runs. Didnt seem weird to me at all. Ive got another cat thats 32" and runs best on a 442. Tried 642, 440, 640.. the 442 was the best for that set hull and combination. I went thru every and all strut adjustments w/ every prop on that one. Took months to find the sweet spot/ prop.

I need to correct myself... The X640 is the one that is similar to the Prather 215... both have 2.520" pitch. The X640 is slightly smaller in diameter at 1.575", compared to 1.614 for the Prather.

The X642 is 1.654" in diameter with a pitch of 2.638".

As for the X640 being faster... If you are running good cells, that don't drop a bunch of voltage under load, then with the stock motor setup, I would still find it weird that you would drop pitch AND diameter, and pick up speed with a system that has this much torque and this low amount of RPM. All of my tests show considerable improvements in speed as the pitch goes up. There was a limit, but it's WAY up there.

I would be interested to see EagleTree data from these runs to get a better idea of what is going on. 2mph out of .108" of pitch DECREASE just doesn't make a lot of sense in an otherwise healthy system.

Of course, if you have changed the motor, then all this may make sense... I haven't been following all the threads to know for sure what motor you are running these days.
