weed eater $65...........26cc zenoah $209




has anyone every converted a weed wacker engine for an fg rc?

RE: weed eater engine
 

What brand is it? Chances are the crankshaft is not right.

RE: weed eater engine
 

No comparison, total different power and rpms.
I ran a 30cc homie in my boat and then put a Zen 260 in it, HUGE difference.

RE: weed eater engine
 

I was originally going to use one for my project, however, I found that cc's do not translate to hp or torque the way I thought. Most engines like homelites, only have 1-1.5hp, and not much torque at all. Look at it this way, you hit some small area of thick grass and you can stall it out at full throttle. Also, the major disadvantage, is finding one with a clutch adds money, and it still again doesn't work well with a drive system.

stock weedeater, maybe .8 to 1.2 hp stock Zen/CY 230. 2.5hp, stock Zen/CY 260s 2.78 hp. HUGE DIFFERANCE> now mod it out. the the differance between a leCar and a Ferrari.

Stock weedie tops out about 6-7,000 rpm, zen RC 16-17,000

RE: weed eater engine
 

yea, your looking at a WHOOOPING 15 or 20 MPH Max. for 140.00 you can guy one of these big 1/4scale electrics rtr cars i bought my 4 yr old neiphew last year that gets to 20. no offence ment, but you dont need to spend 1200plus dollars to get an FG, when any piece of wood, 4 wheels and a piece of chain will get 20 mph with those motors.

It can be done but the price to power is'nt worth it. Stock weedeater engine run around 7000-9000 rpm with 1.0 -1.5 hp compared to a zenoah 14000- 18000 and 4 hp. Plus you would wast your time modifing to make it work.

RE: weed eater engine
 

I can probably make the weed eater engine run really close to a G260. I have done it with the Zen LH engine (which is a really low power engine stock), and it can run with some ported G260's. The problem is the cylinder took so long to port, I would have to charge over $200.00 for the darn thing. So what did I do? I gave the specs I developed away on a scooter site "Scooterjunkie.com" so if an ambitious but broke kid wanted to modify his LH engine to help keep up with his friends, he could.

Here is a vid some kid took last week, after he modified his LH engine to my specs (or he got close--nobody has actually had the patients yet to actually hit all of the specs). The kid in the white helmet is on the modified weed wacker engine (Ported and piped Zen LH engine), and the other engine is a G260 which has been piped, and ported by a young man in SoCal--who has said for the last three years that my engines are junk. Ahhhh all the hype. :)

The young man, who was active in the thread about this LH engine did not leave a post after this vid was posted on Goped nation.com.

That is what happens if one opens their mouth not knowing the facts. Somebody will stuff their own foot in their mouth. Damn---that must have hurt. :)

RE: weed eater engine
 

Anyone know if a Goped Zen 230 is a good substitute engine for an FG. Is the RPM range the same. I have a Goped I don't use & thought to put together a spare for the FG. Any comments?

RE: weed eater engine
 

If the Goped runs wih a Zen G230RC, then it is identical to the engines used in the FG Sportsline onroad cars, and only a tad less powerfull than the G260RC.
It will ned a new carb link.(Or new carb with FG style link)
New/Modified Clutch housing, if it is to run on an Off-Road FG(Maybe also on an onroad, but not sure), and maybe new clutch.

If it is a Zen 23LH, then read Above...

RE: weed eater engine
 

Sure---Just get rid of the stock can for something aftermarket, and you will be pretty happy--most likely. The stock can is very restrictive.

RE: weed eater engine
 

As far as I can tell the Goped motor I have is a 23LH, 22.5 cc ? Is this geared the same as the G230RC1, or the same as the weed-eater motor, which would be too slow for the FG.

RE: weed eater engine
 

You all say weedeater motor is not good. So tell me are any of you mechanics? Because Im building a custom 57 Chevy Belaire from ground up. So Im very interested in more to why it will not work. Please feel free to email me at colonialreb256 at google. But you say It cant work and I will prove it can and be just as fast if not faster than the motors you buy. But I am curious to hear more to why it will not work.

RE: weed eater engine
 

The weedeater engine WILL work...

But a standard Weed Eater 25cc engine revs up to typically 8-9000rpm, and puts out around 1hp

A Standard G260RC04 puts out around 2.9hp and revs up to 17-18000rpm, when ported by a GOOD tuner it puts out around 5.5 to 6.5hp with a tuned pipe and revs up to 20-22000rpm.


If you are really good at your porting work and replaces the standard weedeater carb with a better one, then the weedeater CAN be tuned to be competetive.
You also need to take into consideration that the RC style engines only uses 1 piston ring, reducing internal drag, and creating a better power potential.(Yes, Some Weedeaters also come with only a single piston ring)

A few of the weedeater engines I have seen, also has the challenge, that there is too little metal in the head, making it difficult to increase the size of the "flow channels", from the crankcase to the inlet ports.

The RC style engines also typically arrive with a lighter piston, than the Weedeaters, but that is just a "trimming" matter...
The RC Style engines are also available with a "full circle crank" that increases secondary compression and helps increasing power.


p.s. I am NOT a mechanic, I am best at replacing parts ;)
p.p.s. Sorry for my bad English.

Hobby car is completely different than rebuilding a 57 chevy. Any monkey with 1/2 a brain can tear apart an old car, clean up all the parts and put it back together with some modifications and a manual.... But that doesn't make them Engineers.

PS: 1966 Thunderbird rebuilder here ;)

RE: weed eater engine
 

hey dave,
actually the guy is new to this stuff and he isnt redoin an old 57 he building a full out custom 1/4 scale.so cut the guy some damn slack![:@]

RE: weed eater engine
 

Weed eater engines arent that bad. And the clutches on all the higher quality ones are identical to the zenoahs. A modern husky, stihl or kawasaki weed eater the same size as a G230RC will make good, useable power. Sure it wont make as much as the zen, but you wont have to be reving the guts out of it to get a reasonable amount of torque to the wheels. Plus they are really reliable too!

RE: weed eater engine
 

yup sam has got it there!

RE: weed eater engine
 

Big Mod man, I'm not slamming the guy, I KNOW howmuch work it takes to build restorations, and just compare and contrasting it to small motor modifications is like Launching a manned mission to mars, or just sending up a satelite in a rocket to orbit with some recording instruments. Both are similar fields of work, but on completely different levels of intensity. Just because someone can turn a wrench and play with some body compound and sandblock does not make them FOOSE is all I'm saying. Just kinda odd for a FIRST POST in the forum to be so defensive about being able to mod a motor and it not even being his thread. But I donno. Just looked like a good discussion/ argument bait.

CALL ME A HUNGRY FISH :D

RE: weed eater engine
 

Like Bigmodman said its not an actual 57 it is a 1/4 scale. And as for actual cars I have 2 1969 Dodge Coronet 500's. A 1970 Dodge Truck. a 1952 dodge truck a 1965 dodge truck and a 1966 2 ton Dodge truck. Nothing major and no rebuilding them doesnt make you an engineer. This forum is not about real cars but Cars we can afford or afford to build.


P.S. All the cars listed are my restoration projects. they are slow go cause i want them right.

colonelreb256,
The person you want to talk to is Earth Surfer. He's the Guru of all motor Gurus. My personal opinion, it would make more sense to stick with a Zenoah for any type of RC for parts and available hop ups.

RE: weed eater engine
 

i knew he ment to say that. lol :D and yeah i thought he was sayin that the weed wacke rwouldnt work b/c it does.hehe sorry bout that dave.

RE: weed eater engine
 

Hey Earthsurfer,what do you have for a sportline 04 upgrade?
Just bought a brand new FG sportline and wanna do either some motor work or buy a bigger motor.
What can you recommend doing or buying?
zen 260rc?
or?

By the way,I havent even started the new car up so its a brand new zen 230/4



Im all ears with my wallet open :)
email me direct if needed.

RE: weed eater engine
 

a 23 will actually scream with motor work.. i know you didnt ask me but you get more RMP's out of a smaller displacement.. more rpms means more speed ;) i wouldnt worry about bottom end you'll get that with a good pipe and you still have reed porting go with. race porting the head ect. I would keep the 23 for the on-road
