I took these pictures when i got done cleaning the plane yesterday afternoon.

The picture of the Vertical Stabilizer is there to show my support of the drought situation in the central valley with a brown V.

hope you enjoy...

Very nice!

Clean!

How did you paint the valve covers, I have tried to do that with not so pretty results.

Very slick, I have a question too. With more hp do you have to do anything better with cooling/baffling? I have done some work to my O 360 for more power and am wondering if you did anything like ATV siliconed your front and rear fin baffles on tight or is everything as it was in the cooling dept.?

Knopp up at pponk graciously had his paint department match the writing on the rocker covers to my paint job, they didnt have the exact color, but the sky blue turned out very good...the entire engine was painted metallic silver by them in-house. The baffling is very similar to the old junk that came off, except it fits up in the cowling a lot tighter, and they siliconed it to the front cylinders, as well as to the back of the baffling plates at the rear of the engine...now i can tell a bigger difference in managing the temps with the cowl flaps, im still breaking it in, so it is still running a little warmer then what im used to, but i can tell you that the baffle job is first class because i can really regulate the temps very well with the cowl flaps now! Im still running them about half open at cruise, but i live in the central valley CA where ambient temps are still in the 100 degree range..

Like the fuzzy dice...Graham and his crew asked me if i surfed up to pick the plane up since im rocking fuzzy dice i must be a surfer!!

How much more did your 470-50 weight compared to the 470 you had before? Does it actually grow in size under the cowl as well? I'm wondering if a 470-50 would work on a Bearhawk

Okay that part works then....does it get much bigger with those cylinders from the 520 on it?

You could surely make it work Tadpole, it's a homebuilt after all!
One guy here is talking about putting a turbine on his kit, that would be interesting...

Thanks for sharing 182dude, that is a nice looking setup. Cool to see.

Ya there is that, but I'm no engineer type. I know the 470 works just fine with the plans. I'm probably going to end up with a friend's partial project and it's set up for a 470..including two O-470s that would need to be rebuilt into one...just thinking of if I did take it, making those two dissapear and have a 470-50 in the end...otherwise I'd probably stick a regular O-540 on and sell off the 470 engine mount.

Thread hijack over...

I believe the footprint of the 520 is very similar to the 470, but not sure...i have heard that the 520 and 550 are identical as the 550 is a stroked 520...the engine really to me doesnt look to be any bigger or wider but i have no measurements of before and after...no mods to the cowl and the baffles are the same kit as the 470 so assuming they are very close.

Thanks, and that installation on your plane looks fantastic!

Nice looking installation. How many blades for it to start since you don't have a primer?

I find this very interesting as my primer no longer works and we cannot figure out why??? 2-3 blades and she fires up...

The size is virtually the same as my 470. Really cannot tell a difference.

AKT

It has the primer like my 470 had...in 1974 or 1975 they changed it to inject fuel into the cylinder...mine is a 1973 model i believe it squirts it up into the intake manifold...that being said i think that system sucks and is a piece of Sh!t and just leaks gas out of my primer knob into the cockpit, so i crank it 2-3blades go a quick very quick pump on the throttle and it comes online. If i do nothing at all but crank usually 6-7 blades, it comes on quicker with a quick pump and it runs very smoov doing it that way!

I appreciate the compliments on the plane and the install, they truly did a first rate job on it and this is my creampuff baby so hearing your guys compliments is great...thank you very much!!

Mike

Looks very nice!!

58Skylane, i sure do like the looks of your rig with the big tires...im a big fan of the straight tails! I cant wait until you have the pponk grin because youre gonna love the crap out of it!

Mike

Thanks Mike. I'm really not sure at this moment when or if I'll do a Pponk. Depends on money. We'll see........

Before you invest time and money in that direction be sure to talk to those flying a Bearhawk behind the 470. Its a heavy engine.

This setup looks great however.

Replacing the O-ring in the primer pump will fix the leak (unless the metal parts are damaged somehow). Your A&P should be able to do that in just a few minutes.

Nice pics and plane! They did do a great installation job.
