What is something fun I can do with a 25cc Weed Eater engine? Anybody done anything with something similar? My Weed Eater was borrowed and the shaft got bent, so I replace the whole Weed Eater.

convert it to RC easy enough to do. take the engine apart remove some excess material. put a 18X8 on it.

Thought of that, but I am not big into turning them into r/c plane engines. I do fly planes, but they seem a little heavy and underpowered. Still an option, however.

Anyone ever used one in a homemade r/c boat, or connected one to a foot scooter, or hook it up to a bicycle, or other fun things????

Though I have not done it, I saw a foot scooter that someone had put a motor on. I don't know what kind it was because he zipped past me at a pretty fast clip. Looked like fun.

There was a guy in Hesperia, Calif. that made conversion kits for
weed-whacker engines to r/c use. Unfortuneatly my old pc is down
for service, so I don't have the URL. []

A Google search of "weed whacker conversions" might be fruitful.

They were very reasonable too.

Use your imagination!

I use my McCullogh backpack blower and a skateboard for some "ducted fan" fun.

Converting a scooter to use a weed wacker engine should be simple enough- simple mounts and a centrifugal clutch with a chain drive.

All the parts are readily available.

The latest craze of "pocket bikes" and "mini choppers" are simple minibikes with weedwacker engines. They use slightly BIGGER engines though.

the weadeater is pretty anemic and won't be much fun on a scooter/bike. a piped g-62 on the other hand is a blast! and then there are those who enjoy margaritas from gas powered blenders....


ALL the info on converting these engines can be found right here on RCU's "engine conversions" forum. prop hubs, mounts, ignitions...it's all there

With an 18x8, how much thrust do you think I could get? Enough to push me on a light-framed 4-wheel vehicle? ...maybe using bicycle tires/wheels and light frame. I am thinking on a paved, flat surface. Probably not, huh?

Hum....what else?

My Feedback: (1)

18x8 is kinda big for these engines, 15x8-16x8 is better. either way you'll probably see less than 10 lbs. thrust....


why not try something like this: http://www.crazyherb.com/BigPink/bigpink.htm or maybe a huge PBF?

I have a Homelite 25cc weedwhacker on my GP Dr1, swinging an 18X8 prop and it performs very well. I'm getting around 12lb thrust.

PBF? Sorry, I am not familiar with this acronym.

Here's the one I was thinking of....looks like a pretty good engine.

put the motor on a rc boat but make sure the boat is big enough to hold the weight of the equipment

In our club, one of our members put a converted weed-wacker motor on a big coroplast SPAD. With the weedwacker motor, the SPAD was able to get off the ground and fly around but was underpowered and not very aerobatic. Note that this weedwacker motor had been machined to remove all the excess metal, including removal of excess cooling fin material and so on. So eventually the motor was swapped for one of the newer 26cc motors designed for RC airplanes with an electonic ignition. Wow! the guys had a blast zooming all over the sky doing aerobatics with this SPAD.

Conclusion: don't waste your time putting it in a airplane. If you want to do "real" flying, get a "real" gas motor.

I found them to be quite good in simple plane designs. The picture is of a giant big stik with a 30cc homelite weed wacker motor. Try the Engine Conversion forum, lots of interesting ideas.

I built this Eindecker from an old Carstens plan several years ago. Power was a Homelite 25cc conversion with 16 x 8 prop. A simple converwion and a good match for this airframe. It was easy to fly, perform a realistic Immelman turn, loop, mostly from a dive and handle both axial and barrel rolls. An all round nice model and different from the endless Cubs....

For a period of time Zenoah was providing the engines used on stand up scooters. That engine was originally a G-23 but was later changed to a G-26 when the 23cc engine was discontinued. So a 25cc engine would work fine on a scooter.

Your other options are to turn it into either an aircaft or boat engine. A bit more work and parts required for a car engine.
