yea thats practical...or we could use diesel and run it on vegetable oil or atf or used motor oil or another one of the thousands of products a diesel can burn. i love how ppl like you think electricity comes from magic.

Who cares? Gas is dead and so is diesel! Make a brushless electric alternative with solar cells on the wings and forget reinventig these old technologies. The time to let them go is NOW. Use the 172, make it a 2 seater with a lot of batteries and park it in the sun to charge, then I will get one.

its not been delayed, its no longer going to be made with thielert engines. Until they find an alternative, its not delayed, its gone basicaly.

The manufacturer of the engine Thielert has gone into insolvency and the founder and his CFO have been fired. They were accused of booking false sales to pump up the financial results.The Cessna Skyhawk TD has been delayed due to this action. Don't look for it anytime soon.

Maybe to recereational pilots who only fly a hundred or so hours a year. I am chief pilot for a large pipeline patrol company (13 172's that each fly on average 1000 plus hrs a year) and we are SERIOUSLY considering this aircrft as an alternative.

Wow, thanks for explaining that to a ultralight flyer! I deeply apriciate it!

CS props have the ability to change their angle...the blades of the prop actually rotate within the prop hub. Pilots usually have a control to regulate the blade angle and its used to set the RPM of the engine. A pilot might set the RPM to be 2500rpm, then no matter how much throttle you apply, the blades of the CS prop will change angle to maintain the 2500rpm. Regular, fixed pitch props only have 1 blade angle obviously and don't have this feature. CS props effectively give the plane gears

Very helpfull video, but whats the difference between a constant speed propeller and the other one he mentioned?

well you dont understand diesel technology these daysburns 50% less fuel than a gas engineexpect a 5gph or so rate
