Scale hydraulics????

[Badpony19]

Just FYI, i am working on a closed loop hydraulic system using a C02 cylnder for pressure and a scale dual action ram. Anyone interested i will post my progress...I am building a scale buggy running an .26 stihl engine for power and tlt axles.I want real looks so i am attempting to go all out.. Thanks and let me know

[rockschooler]

it sounds like an awsome idea how bout some pics, and i dont think tlt axles will hold up to the .26 power!

Yes You Must Post Pictues!!

LOLOL my savage was blowing rear difs left and right with a freakin .247.... i bought a billit spool.... but a tlt... by by axles.... but definetly sounds freakin cool

[john alardin]

yeah, the stock tlts probably wont hold up. why dont you send them to me instead. Really though, the stihl engine is a commercial-type engine. while it is powerful for its size, comparing it to a nitro engine is not really justified. look at how little nitro engines last compared to stringcutter engines. part of the reason nitro engines have so much power, is because they have higher compression ratios, and have higher rpm capabilities. If you beef up the tlts, or get bigger axles, I think they should hold up. I love the whole pneumatic system idea, but what would it be for? ride leveling, height adjustment? dont mount the tank upside down, because youll probably freeze all your o-rings, and need a new set. Be careful with high pressure stuff. it can be killer.

sthil 26cc engine???? if so thats a huge engine for tlts id think something like xfactor or kyosho axles and a 1/6 body would be more to size

[run2jeepn]

I got to see this.

I think the .26 Stihl is actually wider than a TLT axle.

Air systems are pneumatic, not hydraulic.

[slobin3d]

are you using a pnumatic system or co2 to pressureize the fluid???

Not as fun as homebuilt, but you might look into a Carson Attack, FG Marder, HPI Baja B5 or a Duratrax Firehammer. I owned a Marder Beetle for about 6 months last year and all I can say is that its a blast. The 23cc Zenoah that was in it would destroy a TLT axle the first time you floored the throttle. That Beetle weighed around 30lbs and it would smoke the tires from a standing start on the asphalt. Even if that Stihl was a little less powerful than the Zenoah, all you're going to have left at the end of the run is a pile of molten plastic and pot-metal shards.

be nice lol

give us more details id like to see what you have planned

OOPS... I slipped, i meant txt axles, not tlt's.... Totally my bad. ANd for all the people out there it is a air over hydraulic system . And it actually works great in real life, cause it is the emergency back up on the submarines i work on. But, me and a buddy( hydraulic technician on the submarine) have started on the design to copy the navy's so we will post some pics when we get started. I dont know how its gonna work, but i have free realm to a 4 million dollar machine shop and all the materials i could want. So maybe it will actually work.... You never know... Thanks for the reply's , hope to update progress soon.

[rockschooler]

is it going to work like this, a co2 cartrig will pressure a hydrolic fluid resivoir and then little valves will allow the fluid to be pressed into the cylinder?
at least i think it will work.

One more thing, just to let you guys know, i have the stihl .26 and its actually quite small.. a little bigger that .27 wasp with a large cooling head. The reason i am running gas is for tunability, not power. I plan on machining a set of reduction gears to limit the speed. i am designing a short shaft drive to a stampede tranny that will be mounted after the reduction gears so torque is my only demon i am worried about. I want the gas to idle and not foul, this is why i am using a chain saw engine. Again, thanks for the interest, i will keep this up as i go.

[slobin3d]

just to clarify the wasp is .27 cu inches 4.5cc, sthil 26cc ??? like the same size as a weed eater motor??

I'm a little confused here. Are we talking about steering or suspension? If you're talking about suspension, saw someone mention ride-leveling, then I have a link that might interest you. It's 1:1 scale but I run it on my rig and works well. I use an air compressor but some have used CO2 in scuba sized tanks. This ia air over hydro by the way.

[Badpony19]

i am talking closed loop for steering, not suspension. And yes i understand that the wasp is 4.5cc and the stihl is 26cc... If you step back and think about it.....that is only 20cc more... If you look at a hospital syringe, 20cc is very insignificant.... I know everyone is skeptical, but either way it will fit... thanks for the comments.

[skidooguymxz550]

is it nitro or gas, in your first post it said .26cc do you mean .26ci

[rerock]
