bloody hell. i bet a few pairs of ski pants went to the laundry that night.

i don't know why they aren't designing swap and go batteries like the trucks and fork lifts are doing.

Where do you get these stories

I have been there. Great bloke's . They do some brilliant work. The radial engines are a work of art.

true, but what he says about adding a crank snout and increasing the bearing area has to help. the jabiru prop extension is probably fine until there is a slight imbalance from prop damage and wear.

good luck with it . looking forward to seeing the demo flying.

That's it. I didn't think to look on YouTube.

is it a certified engine

i had never seen a texan until last week. did 3 hrs dual training. got another 2 on friday then hopefully back to solo. i like the aircraft. flies nice and climbs good. big cabin.

Did you watch that video link. It makes sense.

So you would think a crank snout with more bearing area and getting rid of the long extension should fix the problem . I know when I got my 2200 I thought the prop was a long way from the crankcase.

They are breaking at the first crank web behind the front bearing. He showed one in the video.

there is not much support for the crank snout and they often use long extensions to mount the props. cherna believes the cranks would be fine if they had more substantial support behind the prop.

no . you need a facebook account unfortunately

this video paul cherna has on facebook shows what he considers the problem with jab cranks. Log into Facebook WWW.FACEBOOK.COM Log into Facebook to start sharing and connecting with your friends, family, and people you know.
