i actually sealed up that front compartment! so its bouyant in case it ever trys to sink
i think i can definantly get another 2 bigger tanks in where they are though
got some radio box bellows as well! good 'ol hong kong! £2.50 for 10[X(]
£2.00 each at my local shop[&:]

I like the sealed compartment. But I like foam for bouyancy better. If you hit a another boat and crack the chamber shes going to the bottom.

thats not the front compartment though there is one in front of that!! i also sealed that one and either side of the tank and filled with foam for bouyancy.i left the centre bay open and cut a hatch for the tank bay.its quite a large bay and you can get a large tank in there and its perfectly positioned for balance also.it wouldnt be too hard to cut a hatch in there if you want to!! i just made sure the rails were raised up to the deck to make it water tight in front and either side of the tank.i just glued some plywood pieces in place to do this and it worked great for me.might be an idea for you to try.also uncle crash has it right you need foam in there just in case the hull gets cracked or even if the sealed compartment isnt as water tight as you thought.if you want to cut a hatch just drill a hole in the deck where the hatch is going to be then mark it out between the rails do it slightly narrower so you wont cut into the rails and use your jigsaw to cut it out then once youve tidied it up make some supports round the edge of it to support the lid and fit a lid.there are lots of ways to fasten the lid down and the tank bay doesnt need to be water tight just a snug fit will do.my rails were about half an inch or so lower than the deck so i epoxied some ply to the inside of them upto the deck so it was sealed then the forward bay and the side bays either side of the tank are water tight.thats plenty of bouyancy especially as they are all filled with foam .

but will happily give them to you

rickburnout666

right ignore the pics, just having a try ,
the old engine you see has been tuned by myself and screams like a scalded cat, the water jacket (home made) as you can tell has had a better version fitted but that one did the job, when i was doing my testing,
right now to see if my pics are there
Thanx

rickburnout666

Many thanx Paul

right hey presto a Tuned pipe!!
now dont all shout HEY thats great! at once!!
well i tried playing old macdonald had a farm on it but its not got a lot of tune to it
hopefully it will be louder and give more speed even if its not rocket boost
just dont have the money to buy one at the minute
but its surprising what you can do with tin snips and blow lamp with some solder[&:]
its got an expansion chamber on this one -more than can be said for my mousse can muffler
and i fitted a pressure nipple for my fuel tank so that can only help as well
just need to get it to the waster now for a run

unclecrash

Only thing I see is the pipe preasure fitting should be placed at the widest part of the pipe for the best pressure,constant also. Hope it has a better note than the last one it kinda sounded like a water,plane pipe. Dave

PS it also looks a lot nicer.

rickburnout666

yes i had the same trouble,you just cant play old macdonald without a mouthpiece,LOL
it looks pretty good i will send you a plan and you can build me a muffler for my race can! what solder do you use, i yhought it would melt with the heat??

mrfixitwhite

pressure nipple placing --DOH!! guessed it would be somewhere where i put it! just went by the one in the pic
i'll just solder over it and put another hole in!! lol Cheers!

the solder i use is that thick plumbers solder on a big reel -needs to get REALLY hot b4 it melts i.e blow torch with blue flame or i use my hot air paint stripping gun! 1500c degrees

yes i agree it looks a bit more pro!
should sound better[>:]

rickburnout666

what gauge metal and what type did you use , i should have asked last time

mrfixitwhite

its only steel from a 25 litre paint thinners drum
but when its soldered to a cylinder shape you cant pressit in with your fingers
i figured i'd coat it up with some BBQ paint to stop it rusting on the outside and the castor from the glow fuel should do the job inside!

rickburnout666

It looks alot thicker, than an old tin , i would not bother moving the pressure fitting ,you will have about the same pressure wherever you have it ,have a look at some traxxas trucks the pressure fitting is right next to the manifold

unclecrash

rickburnout666

Great i just sold some more bits on ebay now i can buy a proper muffler ,they are cheap as curry sauce and chips from hong kong

tazmaniaboats

hello mr fixit i saw the photo of the mounts you fixed in the manner you fitted them they are useless as the vibriation will pass through the bolts the mounts must be with bolts [studs ]on each side moulded to each end of the mounting .generally i use mounts that i buy from rc shops but if you want certain cars use them for air cleaner box units and the cost small money in malta about 3-5 bugs
i saw your nice hull i admire people who build there boats as these are true boaters .you learn through errors and time hells the scars.
by the way graupner have a rudder with the same idea you invented as own one .i,m not sure about the pin 1st its small ,2nd metal to alluminium the metal always eats the alluminium try to fit a small pipe so that the pivot works in it like a bush .length is also an issue .
the flat bar you used as a stand make holes in it to reduce weight as you have a small engine.

rickburnout666

Graham on this boat the Centre of Gravity, do you put a pivot point 30% from the transom then balance it with all the hardware in??

mrfixitwhite

Hi tasmaniaboats
yes my motor mounts arnt great but they are holding up ok and everything was fibreglassed aswell so im not to worried
and my rudder as well -now ive done one the next will be better

as regards the COG i fitted all my hardware loose first and marked 30% from transom then balanced it with moving the engine
sits real nice on the water

rickburnout666

yes i thought it went well. right the CG is how i thought ,another problem solved. So at the weekend are you trying the new pipe are you using the same header? and can you wait for the weekend

mrfixitwhite

yes thats what messed up my tank space -i had measured it out to sit behind the engine(nearer the front of the boat)
but when i balanced it it moved the engine back from where i guessed it would go
the space left was 1" to small for my large tank i had planned for it!

sadly im away this weekend[]
but if i can get the pipe on in some way -i may try to run it friday if i can sneak out with my wife knowing hehe!!
i only have to change 1 piece of pipe on the header pipe i have to fit it for a rough trial- maybe even tomorrow!!
i have no idea about tuneing the pipe in or what lenth to start the header at
so i'll start long and get shorter! lol
once i get something done -im itching to try it

i'll be driving on my own this time-when i took the video my wife and 2 children were there
so they all had a drive after the race- yep even my 2 yr old son was driving the boat [X(][X(]
even my wife loved it

rickburnout666

hi mr fix it where is the pond and where are you, i am in kent and have to test my boat in a salt water canal
