Good to hear from you Gary! How’s CupCake doing? < It is very expensive, and sometimes hard to get because the components are made in the USA, shipped to Germany, and back to the USA.> No kidding! We

You don’t like that I said your assumptions are incorrect? We’ll let’s examine some more: You’re assuming those DNS’s are for engine failures? I was there, they were not therefor…..your assumption is

Sir, I don’t know who you know, but I race at Reno. I know Thom Richards No one I know in F1 racing carrie’s around another engine. We carry our tools around and some parts. In all the years I’ve been

< A F1 racer has so much drag that it needs 1000 hp to go 200 mph! > i’m absolutely amazed at some of the statements being posted on here. RZ

< isn't much concern put into making them fly xxxx hours reliably and they have more dead stick landings than the general population.> What data do you have to support this? How much F1 racing experie

That’s on a car, not an F1 airplane!

< I would think the drag penalty from 4 pipes sticking out in the airstream would be too much to bear! I'd estimate a 20 mph penalty. Which is why most all F1 racers have them? LoL Ryz

< Nice and quiet. 😊> Ewww!

What kind? I have a set of short stacks.

The original Varieze had a VW, which like most that try an auto engine, got changed to a Continental. If he’d not done that I doubt it would be the success it is today. RyZ

Agreed! Much more fun to fly. Wish those poor guys always working on their auto engines could go fly too! 😃

< Are you telling me cylinders routinely go 2000 hrs? > Of course they do. Read Mike Bush’s stuff.

< Everything I have ever flown has tried to kill me, and most people get killed behind certified engines. > Only because there are a lot more certified engines flying. There’s no data to prove what pe

< 2000 hr TBO refers to the bottom end. Cylinders are routinely replaced many times before an “overhaul”> Nope. That statement doesnt apply to most the engine I’ve had and many that come through my sh

Of course so read it

You guys keep pointing out one success here, one success there. Once again, exceptions don’t change the rule. I agree It IS a personal preference just like smoking cigarettes is personal preference. S

No one’s bashing auto engine. We’re just discussing reality. RZ

Exceptions don’t change the rule. Auto engnes don’t fly… I’ll go one step further…auto engines are dream killers. There’s no telling how many have wasted significant amounts of time wishing they were

Show me any auto engine conversion that made it to 2000 hours. Auto engines don’t fly. Everyone i’ve known or heard of that’s tried went down one of three paths: 1) Eventually went back to a Continent
