JAG Engines
String Trimmer
Conversion
Thank you for your inquiry into the JAG Engines weed-eater conversion. You will have many happy hours flying the Ryobi engines with the JAG Engines conversion products, mufflers and tuned pipes. Our parts will allow you to convert your Ryobi weed-eater engine for as low as $56 complete! Harbor Freight Tools, (800) 423-2567, sells the complete long shaft weed-eater for about $55. Give them a call. The engines are sold as “re-conditioned” but only have from 5 to 25 minutes time on them. They are simply run, re-adjusted and put back in the boxes and, by law, have to say “re-conditioned” on the box. We use them in our 720R models and sell them completely converted for $178. Ryobi makes over one million of them per year in Arizona.
The Ryobi engines are very durable and well made. They
have chrome cylinder bores, twin rod needle bearings and twin crankshaft ball bearings. The rod is made from two forged pieces of steel and is
bullet proof. The engines are guaranteed for one
year and parts can be obtained from most lawn mower repair shops or JAG Engines.
Conversion
of both the long shaft versions (engines with built-in clutches in the weed-eater) and the
short shaft engines are simple and fun. We supply
all the parts that you will need to get your engine mounted on your favorite R/C plane and
go flying. Our instructions tell you step-by-step
how to make your weed-eater into a great airplane power plant. The 720R and the 725R are both long shaft engines. We now also sell True Turn Spinners!
We now
sell new converted engines using the C.H. Electronics after market ignition systems. These systems are just fantastic! You can get about 8% more RPM than the magneto versions
due to the fact that they can be adjusted to maximum timing position. You can’t do that with the Magneto systems. The weight is reduced from 58oz. To 49 oz. Plus muffler
and the 4oz. ignition system. You can adjust these
to run in either direction! Many of the JAGUAR 31cc
engines have been sold to guys making twin engine airplanes. They are SUPER!
Our
engines are flying all sorts of planes from ¼ scale Cubs on floats to Citabrias, Stinger
120s, PT-19s, Goldberg Sukhois, Pip Dream trainers, Huskys, Midwest 202s, 300s and most
planes from 68” to 110” wingspan depending on the wing loadings. The lighter the wing loading, the better. We are still flying the 82” sport plane weighing 14
pounds that we use in the California R/C Marathon event each May. It flew for 185 miles nonstop on only ½ gallon of gas
for a 3rd place trophy! Team Infinity
flew 235 miles with their specially designed airplane. We
used a 16X12 APC prop on the flight and the engine did not miss a beat. Most planes designed for a 108 two stroke or 120 to 150
and up four stroke engines will work fine for the Ryobis. The
new 80’ Bridi Kaos and Killer Bee kits are inexpensive and perfect for these engines
as well as some of the Bud Nosen Kits. Get you
Ryobi up and flying ……….. You will
really enjoy these great gas engines!
