Have you looked at the FUJI 4 storkes ? they even have oil in the crankcase like a real car.

Here is a pic of one , just put in unleaded gas no oil mixing. This is a 1.50 cu. in.

Hey that looks nice! Still kinda stuck on this Saito engine. May do the FUJI after the Saito http://www.youtube.com/watch?v=Nig3k...eature=related . It will be a while though maybe spring before I get this thing a flying...hehe. I have to reseaarch the FUJI[8D]

This is a very interesting subject, me being an airplane guy also, i love four strokes. but this is what i've been looking at; http://centralhobbies.com/Engines/ys/YS63s.html there are bigger motors that they have, but the rpms on this motor would be easier to gear for,. imo

donoisten

But if you really want power this would be the sh **. http://centralhobbies.com/Engines/ys/ysengines.htm. all of ys motors are fuel injected, supercharged...........

Man that YS Engines really looks nice, can't find any demensions or hp rating on it though, the Saito FA-125 will be a very tight fit but do-able. Now if the FZ110S Engine has smaller demensions but still puts out the same hp as the 125 it might do the trick.

heres a discussion on ys motors.http://www.rcuniverse.com/forum/m_2286099/tm.htm

I cant wait to see your finished project, It should be one bad ***** savage.

Ys motors look neat, bulky things but.
Definately post a pic of the finished machine digger.

Ya me2, My big head brother (hehe) in Baltimore will make the engine mount, he's a CAD-CNC operator and a mechanical draftsman. I'm gona put him to the test...hehe. Went down to the LHS (Lantz Hobby Shop) and they had the Saito FA-125 the silver version though and it's huge but I believe it will fit. I think I should just go ahead and order the black one. Yup beer=food the YS engine seems to be bulkier then the Saito but yield about the same hp (engines mentioned above). The Saito about a tenth more hp. Yes when finish about springtime I will post pix and vids.

SportsFans

Ok hey guy's I was trying to keep things on the dl because I haven't gotten very far. I haven't made that trip to Baltimore to have the engine mount made, hopefully that will be soon. PM'd someone a pix yesterday of the latest, out of all fairness I think I should do the same here. MAN! I can't wait until spring! Much thought has gone into this thingy so let me know what you think. Here ya go. Oh the engine is just setting in there no mount.

Art91

This seems like a cool idea, I can't wait to see it finished.

Vigilante212

Keep it up sportsfan looks great. The motor looks soo undersized in that beast

SportsFans

thanks Art91 and Vigilante212! it's gona have mega torque hope the tranny and diffs can handle it, gearing for speed. Since you said it, it does looks kinda of under size in these pix but it's not. Nearly twice the size of Axial .32 in everyway. Thanks again for the good words buds!

krazenitro

oh god now i got to find a turbo thease motors can spool..lol

thease motors....hmmmm!

Hi .. i write from italy and olso i have this project fot to put a engine 4 stroke in my savage... i have put one SAITO 82 but the big problem is the starting!!! i think that the flywell is too small and don't start the engine... sorry for my english , can you help me for this problem?
Ops.. sorry.. my name is Claudio

rcnitrohead

Hey there looks like a great project! This is tricky because of the flywheel access in the Savage, I've seen a vid on youtube with a 4-stoke powered Savage (modified airplane engine like the 82) but I can't find it.

Anyways, it looks like you are using a boat flywheel? How did you manage to mount the clutch bell onto the crankshaft? Thanks bud.

SportsFans

Wow Claudio that look great, you have gotten further then I have. For the flywheel you don't want it to be too heavy or too large, because that will hamper acceleration. Try to find one about the same weight as a prop meant for your engine size. Now for starting from what I see from your setup something like this might work. Find the right combination (shaft size). Remove the cup and install the wheel, then spin it agains your flywheel, if it's spinning in the wrong direction reverse leads to the battery. That's the way I'd do it given your setup, I hope that helps. Good luck!

Wow I completely forgot that he had cut his TVP up for access, then that makes things much easier!

SportsFans

Ya he still will have to reinforce it though somehow.

i am a fourstoke guy too but would never put one in my savage. all my dirtbikes are fourstrokes but are very advanced. I think you will be very disappointed when you get finished. they do not produce the power of a smilar 2 stroke even at double the displacement. i seen a tmaxx with a four stoke and it was so cool , it had the coolest looking exhaust sounded awesome and was very slow, tons of torque but no snap. would barely spin the tires on dirt. check out this video of a fourstroke savage. correct me if im wrong but i think my f4.6 would be right beside this thing?

Ya I saw that video before, and that's a dual 4 stroke. Every Dual anything either 2 stroke or 4 stroke had dismal performance I could be wrong, but lighten it up (one engine) also a light flywheel geared right you should be fine.
