This would be an ideal time of year to hear from the Zenith forums & bloggers about their tried and true ways to preheat their aircraft. Please posts your ideas and share how you get her warmed up for Winter flight.

On my 500 hour 601XL-B, I use an electric automotive oil pan heat pad (45 mins.) and I also use the electric small milkhouse heater (45 mins.) (the one posted on the Jabiru site). I put a flexible metal tube on the heater and…

I had noted the plug wires as originally run appeared to be blocking airflow into and around the cylinders, so to improve the airflow I changed the location and manner in which the plug wires were run. The photos posted are only a few of those that tell the story of the change and I will try to include more photos as allowed. Take notice of the clear air pathway thru the intake plenums and how the plug wires now are barely visable within the plenum. I also made use of the old plug holes to…

A question for all the Zenith builder & fans out there..."What ever became of the Zodiac Gemini CH620?"

I have the factory information about the aircraft it. I stumbled across the literature while going through a stack of aircraft sales pitches I collected over the years. For those of you who have never heard of this aircraft it looked like a it was a version of the CH601HDS series, with retractable tri-gear and twin Rotax 912 80 hp engines on a low wing. It was a two seat…

I have installed a 2000 Suzuki 1.3 fuel injected engine in my CH701 on amphibious floats. For initial ground running I have connected it to the radiator that was used for a Rotax 618. I'm not thinking this will be the cooling system I will fly with and am looking for information on radiator and cooling system installation from anybody who has installed this engine in a 701 and had thought they had a good cooling system.

I recently came across an email titled "Zenith STOL CH 701, Made in China, $68.00" only to discover it was for a wooden hand made desk top model of the airplane... and not a full-size version like the one pictured below (also a STOL CH 701, made in China):

I think the most difficult part about building my 701 is to find somebody to give me some instructions on how to fly it.I read a lot about it on the Internet but I need practical experience.Can anybody help?

I love to fly and have logged 892 hours in 3 and a half years. That’s a lot of fuel.

I have never liked the lead in aviation fuel. It trashes the spark plugs and the engine oil and of course it’s bad for the environment. My 601’s Jabiru 3300 engine does not need the lead.

A few months ago I started burning premium automotive fuel. I bought two plastic 14 gallon fuel tanks from Costco for about $80…
