Something Different "4-Stroke LST2"
 

Well guys Ive got an lst2 headed my way with an axial .32 and Ive decided to avoid a brushless conversion on this one. The axial will not be used on this. I am planning on running a Magnum XL-70FS- http://www3.towerhobbies.com/cgi-bin...&I=LXHSL2&P=ML

Its one big engine and Im going to need some help on this build. I have been looking around for certain thing that would best suit it and I found these to be closest to what I want.

Ill need some very loose clutch springs or a clutch spring.
2 or 3 very heavy clutch shoes.
25t+ clutch bell.
Possibly a heavier, bigger flywheel.
Bigger mount "looking into the mgt 8.0 mount"

Im also looking into straight pipes aswell but dont know what exactly to get yet.
Also here are a few pics and a video of what it should be comparable to.. :party:

I hope Im still a "brushless brother" to you guys even though Im doing this.:wink:

Something different is quite what we are accustomed to around here :yes:.

If you haven't already done so, take a good look at the MGT 8.0 clutch/flywheel/clutchbell assembly. My guess is that this will be one of the few setups that is capable of working with that engine.

it sounded like me after chili. pppppppppppppppppppppppppppppppppppppppppppppppppp ppppppp pppppppppppppppppp ppppppppppppppppppppppppppp pppppppppp poopy nitro:lol:

I have nothing against a "4-stroke conversion"! :lol:

thunder tigers ek4-s2 had a big .70 in it, might be helpful............

have you looked into the davis diesel conversions, they are awesome in planes, sound alot better than the nitros maybe not as cool a 4stroke convo but alot easier... and no maitence hardly with the desiels and no plugs tanks last twise as long and fuel is cheap in comparison to anything else.

Forgot to ask Ryan, what does a gallon of fuel cost for a 4-stroke? Normal gas or nitro or?

Haha, ya it reminds me of the sound of a 1/5 gasser.

Ya, if it was 2-stroke nitro I would have avoided this forum completely. Would have gotten shot down terribly.:yes:

Got a link to this? And is it possible to do this with an axial .32?

Its cost is up their but since 4-strokes are more efficient that 2-strokes it should even out cost wise... About $9 a quart- http://www3.towerhobbies.com/cgi-bin...?&I=LXA300&P=7

If i were to do this deisel conversion its still just as pricey as the 4-stroke. Around $190 for the conversion. I think Im going to try 4-stroke first just to see how well it runs.

couldnt help but notice the motosport magazine. Cool to know other R/cers ride too.

Personally I would go with the diesel conversion as I have heard they can put down some pretty good power, and it seems to me that the 4 stroke conversion would be pretty technical, and would require lots of custom fabrication. I bet the power would be pretty nice(I ride a 450 so I know 4 strokes can kick some ass) but I dont see it being worth the trouble.

oh yeah you might want to invest in some shocks. Haha JK

The 4 stroke sure sounds better...

I agree.

Yeah, even if you did the diesel conversion not many people would know beacuse it sounds like a mosquito on cocaine still....

Lol...

the deisels work by like tripling the compression ratio. I see it eating one way bearings.

I saw this a long tine ago. http://www.youtube.com/watch?v=1H8MNHbqXLA Torky

Takedown showed me a video of a savage with doal .40s... That was torquey.

This one:surprised:- http://www.youtube.com/watch?v=ioGFZEAa90A

Ok guys heres an update... I got the LST2 today and cleaned it up. Looks like it will be the perfect truck to do this conversion on. Lots of space to work with and the truck is solid. I might take the .32 for a few spins before its replaced though.:lol:

No... you will replace it now.

Got ear plugs? It sounds cool as hell though. Reminds me of my buddy's banshee with toomy pipes.

Haha, Im a rebel...:wink: Anyways here are some pics of the lst2 with the msr8's on it...

No, you're a conformist. Brushless is the rebellion my friend.

Hmmm.... Actually no. Brushless is the new now. I guess Im getting oldschool.:lol:

No.











,

Don't be a hater Ian, just cause you can't tune nitro's .... :lol::na:

Glad to see you are finally going to run something with a combustion engine in it!

And since you are running 4 stroke, you can run a straight pipe.....

So if you could please, run the pipe right out of the side of the body of the truck, and make it a short pipe, and then run it at night and get a video, because I want to see the flames coming out the exhaust pipe!! :diablo:

Anyway, good luck with it. If your results are really good, I might just consider stuffing a 4 stroke in my OFNA Mutilator truggy (As much as I would hate to get rid of the beastly .32 it has in it right now)

4 stroke or two, it doesn't matter...They still spew smoke and make to much noise. My E-Revo on 5s has more torque than any of those trucks in the youtube videos

just remember when your moving from 2 stroke to 4 you have to go up in displacement. If you really want to get wild i know Saito makes a new FG20 4-Stroke Gasser. if you can find a way to move the crank sensor you could use that evolution has one also small 4 stroke gas that is..

.40 2stroke = about .72 4stroke nitro

Hmmm...

The 4-stroke noise is a exception...:yes: But it will be something very unique and thats what Im aiming for. If I end up not liking it which I doubt I wont. Ill convert it.

ya power to weight ratio a 2stroke will outperform a 4stroke. BUT w a 4 stroke the sound, torque, and fuel conservation is often worth it to us airplane guys.

I think that is right because on a 2-stroke you make power on every stroke where on a 4-stroke it's every other stroke.

a 2 stroke will always beat a 4 stroke of the same displacement. A power stroke every 2 strokes or a power stroke every 4 strokes. 4 strokes are much more reliable, but this is r/c! What's reliable?

you mean every revolution, or every two strokes for a two stroke

ya ...just try slinging a 19 inch prop with a 2stoke.

Or just give in and go Brushless :)
