    Viable USA Part 103 Kawasaki Engines

    As usual, you want to deflect from what was asked! As I have said before, show us a Side by Side an Equal Dyno Test. Same CC, using the same Airplane rpm, same Size Carb, same CR, same Exhaust, 2 Port vs a 4 Port. Yes, the Higher you turn the Engine like for Racing the 4 Port will outperform...

    The Chaos 400 Ultralight Aircraft Engines is a 4 Stroke. The Yamaha/Arctic Cat Blast 400 397cc is a 2 Stroke and makes 65hp@8000rpm. For Airplane use, you would want to derate it to Max 6500rpm so it will last longer. 397cc/7cc= 56.7hp@6500rpm. Still respectable HP! Airplane use vs Racing is...

    A Predator 212 Hemi is $149.99 and even less when on Sale. Upgrades I would do Cost $550-$600. A Simple Belt Drive as shown in the Video above could be Built for less than $200. At $149.99 + $600 + $200 = $949.99 per Engine. A Hirth F36 (Solo 210) 15hp was $2,882.00 each. I put one of these...

    Viable USA Part 103 Kawasaki Engines

    As usual, lots of guessing and b/s, but No Real Facts Dude! A CAN MUFFLER and a TUNED STYLE MUFFER is not a TUNED Pipe. Rotax's UL Exhaust is a Tuned Megaphone Header Muffler combo unit, which gives a little extra Power over a CAN Muffler but nothing like a Real Tuned Pipe does. The Skidoo...

    The Lazair Ultralight

    As a legal USA Part 103, he only got about 35 Minutes of Flight, since the Batteries were included in the Empty Weight by the FAA. Also, his Target Price was very High I think around $35,000. so it wouldn't Sell very well. He should have just updated it to use the Honda/Clone GX200/212's built...

    Viable USA Part 103 Kawasaki Engines

    There have been a lot of Sales Gimmicks over the last 40+ years to increase Sales. They say Rotary Valve is better than Reed Fed, and Reed Fed is better than the Piston Port. 4 Port is better than 2 Port. In 40+ years I have never seen a Fair comparison of all (3) to Prove any of it. In Racing...

    BELT DRIVES for 2 Strokes?

    Who is making New Belt Drives for 2 Strokes today? Challenger makes one for their Engines as does Hirth, Polini, Fiate, and Simonini. Photos and web links would be appreciated. Any Plans sites would be appreciated. ACE makes Belt Drives for Honda/Clones and could be adapted to some 2 Strokes.

    Boy oh boy. Are you full of it today? Lots of personal Theories and Speculation, but No Real Facts. There is No Engine CFM Calc that asks for how many Transfer Ports an Engine has. Account It's based on the Engine VE and Bore and Stroke and rpm used. In No way does it move a larger Volume of...

    Viable USA Part 103 Kawasaki Engines

    There were 33+ different Brand Name Sled Engines at one time. Some, like JLO and Sachs, made about Ten different Singles each. So 100's of possible Cheap Alternative Engines to use. Some have Bolt Holes around the PTO to attach a Belt Drive. Some don't. For some like Kawasaki 340/440 Twins...

    Viable USA Part 103 Kawasaki Engines

    I agree ACE makes one of the Best Belt Drives out there, also the cheapest. How long from when you Ordered your Drive did you receive it? He was saying 6 Months. IF, you buy your Material close to the OD that you need, the Machining Time isn't that long. eBay and FB are the cheapest Places to...

    Many USA Part 103 Ultralights flew on a 22hp Zenoah G-25B-1. Did they Perform as well as they could, probably not. The Rotax 277UL 28hp used a MegaphoneHeaderMuffler Exhaust slightly better than the Kawasaki 292 Can Mufflers. The Rotax 277UL used 11.8cr vs the 292 11.5cr. The Rotax 277UL was...

    To answer your question. I doubt it could make USA Part 103 with "2 V four-stroke industrial engines". With (2) Honda/Clone Singles GX200 to GX270 it can make Weight. By it's MTOW it only needs 13.7hp per Engine to Fly Well. Could it be made Simpler to Increase Production Numbers, Yes. Could...

    Not sure where he is at. I just saw one on one of my FB Feeds in Wisconsin for $2000 with those Big Oposed RC Engines. Looked clean. I don't care much for them RC Engines. I would use the Honda/Clone GX200/212 Engines today. The GX270s are the largest CC Small Block Engines. Not sure How Big...

    A Techno Isle CNC Metal Lathe - First Power A Centroid Acorn CNC Control upgrades Constant Surface Speed on a Techno Lathe. Acorn upgrade was $350.

    Yes, there may be machining needed if you can't find a Stock Kawasaki 292 Piston. The last time I looked, Head machining was $80. Cylinder Boring was $60-$80. If you can do it yourself, it's just your Time. While I have seen cheaper ones on ebay, your statement "When E-Bay pistons show up they...
