I've decided to make this post to give people (who is looking to buy this boat) some idea what is this boat is about.
My intentions are not to give this boat a bad name, just show people about some thing which will happen' shortly after the purchse and will need fixin' right away. my be I just had bad luck :(
I am new to RC boating and the nitro hammer was/is my second boat. it is less than a month old right now.
this boat goes for $210 dollar at the local hobby store,
for that you get a RTR - ready to run boat with a radio(transmitter/ receiver, servos)
.15 nitro engine (made by aquacraft. ) with direct straight propulsion system.
the GOOD
it is easy to break in, easy to start, pretty predictable, and ride smooth on the water , turns fairly well. fun to play with it.
the radio works good , while it is cheap looking with the most basic features.
The BAD,
leak water throught prop shaft at a steady but good pace, have to scoop some ater each run.
plastic rudder very flexie ?, and it is mounted too low in the transom , it sems that it the mounting hardware is draging in the water throwing a rooster tail.
it is not too hard to move it up a notch.
has a very small fuel tank.
has a jam packed radio box , and yes it will allow plenty of water in once the boat is flipped.
the hull is paper thin.
the engine seems to run hot all the time, regardless of adjusments on carb needles. may be not enough water flow? not sure
THE UGLY !! :(
as I stated my boat is less than a month old, check out he pictures below:
the stringer, where the engine is mounted, is cracked. (look at the picture) all engine mounting bolts rathled loose. they should have put rubber mounting
the exhaust(header to muffler) coupler split open. (picture)
the mufler/pipe ratled loose from the hull at the rear.
it blew the gasket between the engine and headerpipe , I tink it is because this header pipe is not made for this engine, the ports are completely different,
not only the header has a much smaller opening (which can be cut larger witha dremmel tool ) but the engine has a very narrow and long port , the pipe has small rectangle taller post which makes it very hard to seal with paper gasket.
every single gasket is leaking on this boat, Hobbyco must have use some china import cork gasket. let me list it.
all fuel fittings at the fuel tank bottom and top where the exhaust is routed back in. leaks where it gets to the carb, leaks at the primer plunger.
gasket leaks at where the fitting is fitted to the exhaust pipe( see picture.)
it eats a glow plug at about every 3rd fuel tank, these are the glowplugs reccomended by the factory.
let me see what elseI am forgetting, I will ad more as things come up.
as you can see I have degutted everything except the engine,
will install a larger gastank , and fit new radiobox in it.
