Default .10 rigger build

Hey all
i am making an outrigger from the predator plans to take my little o.s .10 max marine engine
my first problem is -i know nothing about riggers!
my second is that my engine doesnt fit in the tub!
it only has a small muffler on the side of the engine but the Predator tub is only 2 3/4" wide -my engine needs 4" to fit the muffler into the tub aswell
so can i just make the tub wider or would it be better to mount the engine higher out of the top?

i've been trying to get a bit of info on the motor but no luck so far! any one got any info like RPMS and maybe a starting surface prop size!

Thanks
Graham

Hi Graham!

Your first problem will be the biggest.

If you raise the engine up, keep in mind you will have to move it forward as well, and in doing so will change the cg of the boat. Sounds like a can of worms. Don't take this the wrong way but it sounds like problems snowballed to the inth degree.
Riggers are not easy nor forgiving.

FWIW.

Cheers- so raising it is out of the question then lol[&:]
but im guessing that making the tub wider wouldnt change it to much? it runs really on the back sponsens
im gonna have to go that way coz thats the only way its gonna fit
well this could be a benchmark project then!! someones gotta have a go- might as well be me

im not aiming for a rocket boat- as i will be making all the hardware to go on it-mostly out of stuff i got laying about
probably gonna make somethng along the lines of a fullers setup
but an just entry into riggers and a boat for my 'ickle engine will be fine
got nothing to compare it to anyway lol

got my carbon sponsen rods coming
sponsens are made
do riggers have any bouyancy in them for non sinking purposes!
or are the sponsens enough with a sealed radio box?

Are you using a muffler canister or a header with a pipe? I would recommend using a header to save space. I believe MACS make one for a .1 or bend your own.

My .12 'riggers have the tub low enough for the exhaust to hang out whether it is using a pipe or muffler. If you need to you can always trim the side down for it to fit.
A good 'rigger rides mostly on the back tips of the front sponsons not the rear. Those are mostly there to hold up the back in the turns.

Right ok !
well i wasnt quite sure and so i went for the wider tub! maybe im wrong but the final build will tell!
I did consider cutting down the sides Ron but thought it might let in the water lol!
did'nt want to sink b4 i got going
so i widened the tub to take the motor and muffler and then maybe exit the exhaust through the side.

Carbon spars have come! nice!!
a scrub with some paper and epoxy should place them just right i hope.
coming along soon i hope!

Well like you said I get bored quick so I took an old stack of print paper used one side put it in the printer used side up. And printed out the Plans for the Blazzin. This should do fine for the HPI motor. Nothing to get in the way of the air cooled head. I tried to get this plan off the site a month or so ago but wouldnt open for me. Dave P.S. Happy buildin

good good then!
only thing i noticed with the Blazzin plans were the sponsen pieces.
the sides didnt seem to match the tops????
maybe it was just me
i got over it by using the predator sponsens-theyre the same sizes almost
real easy build though!
you got a winter spring project now

It might be because there is a taper or the sides radius in on it or something I will deal with it when I build her. Right on I love scratch building from plans. Especially when I dont have to hassle with going to the print shop to have them expand or shrink the plan then be told they cant do it and waste my time[:'(] Dave

Well hows going all?

I think i am gonna try building a .09/.12 rigger. one thing i see that i have a question regarding is the sponson tubes, the holes that enter the tub seem to be sloted a little? why? i also read that i am suppose to run a 4-40 screw thru the bottom of the hull locking the the sponson tubes in place is this correct? thanks all I am just really looking at the designs now and plan on trying to start building a little this week if possible. also i have seen someone say DONT use balsa? ive been looking at the firefighter sight and they say balsa on the inside of sponsons and balsa or spruce for the nose of the tube. i was gonna go spruce for the nose I just wanna build the best boat i can and the best design possible. Thanks all have a great night and good luck and good boating

Slotted for adjusting the sponsons you put shims under and I think you do tighten them from below. Yes they have 1/4 in. balsa in the sponson plus foam then the outsides are liteply.

If you're referring to a 'rigger like the Firefighter .12, those are there to adjust the AOA (Angle Of Attack) of the sponsons. I never got into messing with that stuff though as mine were already preset.

Default RE: .10 rigger build

with regards to using balsa or a soft pine- i would use it for the nose of the tub- its more for ease of shaping than toughness
i think if you hit something your gonna wreck it big style so a bit of hard er wood probably not gonna help to much.
Balsa for the tub sides -well there is hard Balsa but i would go with ply! but thats just me.
on the predator plans i think the holes for ther sponsen tub are only round! lol
i did wonder on the Blazzin y the front hole was a weird shape [&:]thanks for the info there!!
gonna get my tub glued up today-maybe get a pic or 2
i think im just gonna glue my sponsen spars in with epoxy unless someone says otherwise

I would glue them into the sponsons but make them adjustable at the tub. Thats how you dial it in. By changing the AOA like Ron said. Dave

Heres a little trick for you. for your next boat when you are making two sides two sponsons and you need holes clamp or tape them together and drill the holes through both pieces then put them together. it will make the holes more precise. Like for the sponsons I would clamp the two insides together drill for carbon rods then put them together. keep um cummin. Dave

Default RE: .10 rigger build

can i ask what size prop to start with on my O.S max FV .10
and also what size flex cable?
would .150" be ok as this is what my vee runs and i have some left over-
i would be able to utilise for all boats then if i bought a long replacement

Thanks

Well the .12 firefighter say a good place to start is with a prather 215. So thats what I will try first since i have one sharpend & balanced.

I would look for a prop somewhere around 34mm with a decent pitch. I'm not too sure how powerful the .10 is. I do know that I use a prather 215 for a 3.5cc (.21) engine.

Default RE: .10 rigger build

Cheers Ryan- i did think that the rather would be a touch big -as im running a 45 mm on my .40 and the prather is a 40mm!
but i do know they say start big!

The builds going ok- kinda slower than i like lol. as im ALWAYS tight on money(who isn't lol)
i like to make whatever i possibly can-might not be the best or lightest but hey i do it for fun not competition.
So at the minute im just started on the rudder/strut hardware
made the strut- although its out of steel it doesnt feel much heavier than a similar sized piece of aluminium
its slotted and i soldered a doubled brass tube at the bottom for the shaft
looks just like the real thing -once i give it a lick of paint lol
as long as it doesnt sink when i stick it in the water -it will be fine !!

drilled the sponsens for the carbon spars and fitted to the tub.
just need to epoxy the lot together

Does a rigger have any compartments in it ? apart from say the radio box ?
i was gonna add a couple of buck heads in 1/16th ply just to stop any water coming in from the engine bay area as the top is open?
would that be a good idea???
i'll post up a pic or 2 of the hardware as i go

Well according to the plans yes ther is some compartments. One wall seperates the radio box from the engine compartment. There is also another small one between the the nose and the front sponson rod. I hope to have my sponsons done today.
