I changed my mind. I am going to do a metalic charcle grey instead of black. I took the radio box out one time, what I had to do is take the pipe out and cut the epoxy with a knife. Once I got it started I just pulled and it broke loose. Be careful not to rip a chunk out of your stringers though. [X(]

The surface drive I am going to get is

Failsafe is a great electrical device to add to your radio system. It will help prevent a run-away in case your on-board rx battery gets too low in power to power your throttle servo and/or if you lose your tx signal.
A very good, small, lightweight unit is the DTXM4000 offered by Duratrax.

It install it, all you do is plug it in between your receiver and throttle servo. Turn on your tx then power up your rx, push the set button and your done.
If you lose power to the receiver while running your boat, your throttle will go to neutral install of what usually happens....full throttle run-away and damage to your boat.......

Hope this helps, have fun!

If they want to get technical, show them this:

IC 9-13-2-198.5
Watercraft
Sec. 198.5. "Watercraft" means a contrivance used or designed for navigation on water, including a vessel, boat, motor vessel, steam vessel, sailboat, vessel operated by machinery either permanently or temporarily affixed, scow, tugboat, or any marine equipment that is capable of carrying passengers, except a ferry.

The sign is referring to a conveyance for people not an RC Boat however, if it's privately owned they can tell you that they don't want the RC Boat in there either. It sounds like they have a problem with noise in that area and probable have a noise ordinance in effect. I'd run the Hammer anyway until somebody tells you otherwise.

I thought that the Nitro Hammer has some kind of failsafe, cuz when you turn it off it will just run in circles 'til it runs outta gas!

O.k. I guess I will run over there. I am going to start painting my boat this weekend hopefully. I will post pics when I get it primered and I will let you know how it goes. I am going to keep the color a secret so it is more exciting to see. Wish me LUCK!!!!!

Another thing that is cool about a failsafe if you lose battery power or it gets too low, you can easily program it to keep a little bit of throttle so it slowly allows the boat to come to shore, or go in circles so your engine does not rev full rpm's for the entire tank of fuel. This is really good if you get upside down and the engine goes to full rpm with no load. When that happens, you can just shut your radio off to bring the throttle setting down until the engine is starved for fuel and stops running. (which is only a few seconds anyway when it gets upside down, but it could help save an engine)

for the surface drive on the nitro hammer, what prop would you be able to put on it? would the surface drive make it go about 40? and would it be stable enough to drive?

It wouldn't make 40 but the handling would be better. You would run a way bigger prop than factrory. Not sure what size. It would point the prop thrust in the right direction rather then down into the water.

Just a quick question. Has anyone changed engines in one of these?? I am thinking of getting one and putting a .21 OS engine in it.

Well after helping a friend run his engine in on his new hammer me and another friend have decided to each get one. I have thought about it and am not going to change engines.... Well not yet anyway. I think for now I might just put a tuned pipe on it and leave it at that. I would be interested to know what other cheap mods are effective.

some mods you could do are these:

buy a octura x427.

drill a 1in hole above the carb.

make ride pads and put bigger trim tabs on it.

shorten the rudder a bit.

shortening the rudder creates less drag therefore makeing it go faster. but leave enough rudder so it can still turn!

sometimes my NH will get airborn and the rudder will come all the way out of the water. big fun though.
