$560 from a local lawnmower shop! Do they sell just the engine?

Joe

80cc and 4 stroke. Now you are talking. Does anyone have any idea of the power head weight?

Bill

Hi Bill, at $560 it is a bit spendy for a chopper. Maybe Ralph will enlighten us if he know what is up with this engine. Not quite 5hp says the specs but it's getting close to enough power for projects I can think of, if it stays moderately light.

My Hawaiian Shindaiwa dealer was going to send me one to convert, haven't seen it yet...Based on the Stihl 64.9 four stroke I would estmate the weight at 6 lbs or less when converted to electronic ignition....The Stihl is prettly close to a G62 in power, the Shindaiwa should be stronger...Both use oil in the gas so inverted mounting is not a problem....

The appearance of more and larger 4 strokes probably means the manufacturers will continue perfecting and extracting more horsepower in the coming years. And yes $550 is pricey.

Bill

Any news on the shindaiwa Ralph? Is the stihl 64 FS easy to get? How much are they? 6lbs or less I agree would be the breaking point. Tell us somethin good!

JOe

I sure hope this is the case Bill. IMO I would like a power to weight that is not available right now and the current breed very limited 4 stroke offerings are WAY over priced. I wish we could just pick a cheap 4 stoke glow and convert it for gas but I guess that is not in the cards. Kind of like what Keith did with the G90 ST at BME, but with some real ballls and displacement to swing a meaningful prop powerfully!~).

Joe

if you go with the stihl get the br550 not the br600. they have the exact same 64cc engine, only difference is the fanwheel. br550 is $399 br600 is $479 at one time they were talking about making shortblocks... i'll find out tomorrow and post.

Thanks Tripp3D! Please do. Does anyone have numbers and prop information for the stihl 64cc?

Joe

I took a look at specs on both machines and I was mistaken. the br550 is actually 64.9cc and the more expensive br600 is 64.8cc not that that little difference would matter much. both are rated at 4.0 hp, i think i'm running a 24x10 on mine but it has only been run on a test stand without a tach. soon to be mounted on a 30% EDGE

sorry, but i think the shortblock is only avail for 4mix trimmers(34cc), probably not all that feasible anyway.

I imagine the cheapest way to get one is to go to a Stihl dealer and ask him what he'll take for just the engine. That leaves a lot of parts to sell for the dealer and not a bad deal for anybody. A friend of mine has a br600 that ended up needing the backplate when his blower (mounted on trailer rack) kissed a telephone pole. Just so happens I had one on hand after my conversion

Thanks for the info Tripp3D. Please let me know what brand of 24-10 prop and RPM you are getting. I got an airframe that might work with that if the power is up. H9 suk lightened.

Joe

Ralph, any news on the shin 80cc? Can your source get just the engine?

Tripp, I saw your post about the edge! Congratulations!! I want this 80 to go on my hangar 9 sukhoi.

Joe Kelley

Thanks Ralph!
I bet the 80cc will pull up stumps
I think my next upgrade will be a decent prop, something better than my Master Corkscrew...
what are the specs on your sukhoi?

Anyone heard anything about this 80cc?

Joe

It seems that Shindaiwa now has spare parts for sale and looks like an engine could be assembled from them. Can anyone take a look for me. Ralph?~))

I am not sure where and how to order yet. My interest is in the 79cc 4.5hp. = 50cc 2 stroke.

Joe

It would cost a small fortune to buy the parts.....Maybe I can contact my Hawaiian connection ..

Thanks Ralph, it is reasonable I'm in. This engine might power some of the popular 50cc size stuff. Sure would make it easier to put in a full day at the field with that 4 stroke sound! The design elements of this engine really are interesting. Let me know what you find out. I got a price of $575 here for the whole back pack blower. Pretty spendy.

Joe

Ralph, et al:

I bought one of the Shindaiwa 80cc's to convert but my shop has been so busy that I haven't had time to devote to it. I'd be happy to sacrifice it for the cause if Ralph wants to give it a go.

There are a couple of challenges I see with this engine:

1) It is extremely tall. The coil is mounted underneath the flywheel (as viewed with the head at 12 oclock) and in this configuration it is 12.5" tall. However, if the flywheel and coil were ditched and electronic ignition installed the working envelope of the engine would be about 9.25".

2) This unit has so much compression that without the big blower impeller acting as a flywheel it is virtually impossible to turn over. I tried mounting it on a bench and starting it with the pull cord but no dice. I'm 6'5" 250 lbs and pulling as hard as I could I couldn't get it to turn over smoothly. So my guess is that for any application in a plane one would have to put some sort of compression release on it just to get it started.

On the bright side I'll bet this thing would be an absolute monster in a plane, and it sounds really sweet when it runs. Ralph, if you think these obstacles can be overcome please feel free to contact me and we can talk about how much/how difficult it would be for you to convert.

Thanks for coming in Tom. I hope Ralph will take you up on it. I want one of these engines if certain thing can be done. I can't wait to see and here one run. Do you want to sell yours? I want Ralph to convert one for me. The compression is very very intriguing!!!~). Lets see what Ralph says,

Joe Kelley

Tom,
I've got just the plane!~).,

joe

If Tom sends it I can bring it to the IMS show before sending it back...

That would be awesome Ralph! I'll most likely be at the AMA show on that saturday. I'll bring a camera too!~).

Joe

Ralph,
The engine is boxed up and should be on your doorstep by the end of the week!

Joe,
Thanks for the generous offer but this engine already has a home in the snout of a Nosen P51. It will be at least spring before it flys since the reduction drive/variable prop system is still in development, and I'll certainly want to spend some time on the test bed with that before committing it to a plane...
