better pics of my hammer

[BoatDoc]

i got a hold of a better camera...so i'm putting up better pic's of the mods on my hammer. the first is a pic of the fuel tank, it's a sullivan 4 oz.

[BoatDoc]

here's a pic of my infamous ride pads. not for the faint of heart...they require MUCH larger trim tabs to keep the boat under control. but the pay off is a better plane and higher speed.

[BoatDoc]

and here's the transom, all hand made except the rudder and the rudder arm. the rudder is from a miss bud.

[BoatDoc]

last but not least. the wet exhaust. i tapped to 6-32 holes into the pipe. the one closer to the engine is for fuel pressure and the other is for the water. the pipe is from my miss bud. the engine really responded to it, and there was an incredible boost in torque and rpm.

wow u have alot of mods! i have been waiting to see some pics of that thing...

just two questions, y do u have a 12v starter belt in there and a pull start on?? And do those ride pads realy increase speed? i would think that it would decrease speed because of drag, how much speed do u think u get?

[BoatDoc]

the starter belt is for when the engine is cold. it doesn't like to start sometimes! once it's warm the pull start will get it going every time. plus i didn't feel like trying to find a backplate if i removed the pull start. the ride pads actually reduce drag by making the hull run a lot dryer. it planes out a lot higher. this also allows me to go topless.

Hello BoatDoc, Nice work!

I am quite interested to make a pair of ride pads like yours?

I just want to ask a few question

1. The diemensions of the ride pads, the thickness, the length, the width and also how wide apart between the two ride pads?

2. what is the green stuff that place in between the propeller and the tube of the propeller shaft?

3. Would it be harder to turn with the ride pads installed?

4. Does it easier to flip over with the ride pads installed?

Thanks in advance

I saw these Sullivan TigerDrive units when I was in toledo & thought they were pretty slick. If you have to start it with a belt the first time anyway, one of these will replace the pull starter all together. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGFK1&P=7

[BoatDoc]

the ride pads are 1" wide, 1/8" thick and 11" long. they have a piece of wedge at the front to create a ramp. the pads are made from bass wood, and the wedge is balsa. each pad is placed 1" from the keel. there was no engineering involved...just a little lucky guessing. but i imagine if they were placed another 1/4" away from the keel the boat would be more stable. and yes, the boat will flip easier. that's why i made the larger tabs on the back. they are little more than thin aluminun sheet that i bought at the hobby shop. in smooth water, this thing is a rocket, but chop requires a careful touch and a good set of nerves!

BoatDoc, Thanks for the information.

Dave, I got one of those Tiger Drives for my kids Nitro truck at the Toledo show. Pretty slick and would be great for getting rid of that pull starter plus as cheap as a replacement pull starter. One problem though, the shaft and bevel gear came apart on it after one days run. I e-mailed Sullivan and they wanted it back, it was the first one that they knew of that broke. They have a Lifetime warranty on them so any problems, send it in. Use a cheap 12 volt drill and it'll spin the motor right over.

[BoatDoc]

i'll have to see if i can fit one of those starters onto my hammer. i love gadgets!!!! but i've spent my hobby money for the month!!! i've got two riggers to build, so my hammer will go without any new mods for a while.

[BoatDoc]

i ditched my y534. the engine was spinning it but it just kept flipping the boat, and i didn't want the hassle. even playing with the trim didn't help much.

[OHIOBH]

are the ride pads coated with anything? you know to make the wood water proof.i was thinking of making something out of plastic.

[BoatDoc]

they are coated with epoxy. i also throw on a coat of turtle wax every couple of weeks.

[Bmuncie]

That Hammer is nuts! Thanks for sharing the pics. I dont believe there is another Hammer out there with that level of mods on it :cool:

[BoatDoc]

thanks!!! i've spent a lot of time on this thing. i'm really just trying to find better props for it now. the last one i tried just flipped the boat over.

[Baja-Destroyer]

if u find a prop tell me ive used the x435 and the prather 215 and they both sucked lol the stock has been the best for me as of now my only other mod on mine hammer is a macs pipe that i put in for the stock one

[racing05]

ron can you get on AOL so we can chat about boats

[racing05]

also on Another Note Any one Els have Probs where the Stand sits on the boat craking becase of trying to start it? what is a good way to fix this? some Fiberglass Epoxy???

[Baja-Destroyer]

yes i cracked my hull i got some pacer fiberpoxy it fixed it right up

[mustangman05]

Is your engine draining water into your pipe?? if i follow the tubing correctly it is
wouldent that just make the water pickup bubble when under water from the exaught pressure or am i overcomplicating things???

[Hydro Junkie]

No you're not and no it won't. You have to remember that the water pick up is a ram feed, so the only way water will get pushed backwards is if you are sitting still, in which case you will be dead in the water with a boat that size

[bertsbackyard]

have the changes you made ,,, are thay for the better ??????? and all so what are the rid pads made of and that glue if any did you use to put the on , i already changed the plastic prop , and that made a big difrents , i dont like the the so called water proff white box, need to do some thing with that lol

[bertsbackyard]

i think he wants the thing to fly lol , he,ll be puting on wings next , lol sorry i just had to say that ;) Look were dos one stop with mods you no what i saying , you can go on and on , and spend more mony for what , Just spend more time in the water with it i say , all you need to change is the plastic prop , to a size 30 metal one and watch it fly and 10 or 15 % nitro no more , and no more mods for this boat , youll end up blowing it up , its like any thing , one can over do it , and to the point were it ends up working like crap rather than better, hay im not saying not to do any mods, just dont try to put wings on it lol be happy with what you got.
and dont forget the prop ;)

Well, I can't speak for everyone but, tinkering and doing mods is half the fun.
Thats part of the hobby, at least it used to be. When I started into R/c there was no such thing as RTR, ect. You made everything yourself and knew your model backwards and forwards. Today with the RTR's and such there are a lot of people that don't really know there model's at all. If something goes wrong or breaks, they end up at the LHS counter saying HELP ME :o .

So in closing doing mods helps you know your model more. So thats a good thing. Plus, as for the Hammer, there are some much needed mods to acheive a really great handling boat. Not just a prop change!

[bertsbackyard]

ya no i wasent having a go at you about your mods man , not at all i was just making a joke , with the puting on wings lol,

i must say i got a lot of info from your posts and your photos , so your doing well what id like to no is how do,s the boat preform with the rids on it????? more speed or no ???

ow and PS i was told by some one to put up the rudder some more , cos its 2 low , less drag if its up , i see the cents in that , ay so get back to me on the rid pads by

[CFRACR]

bertsbackyard-If your responding to my post. I did not think you were poking fun.

Boatdoc & a few others have installed ride pads, I on the other hand have not. I have done many, mods to my Hammer, but that is not one of them. So I can't speak regarding performance changes. I have no need to even try them for my Hammer could not handle any better I feel. Its a toy-boat for me, I get it wet here and there. I usually run my other hulls, but if one is in the shop :rolleyes: , it becomes Hammer Time!!! :D
