Painted it in Marine dress

>2. How much does a Shark 45 weigh?

More than a Skylark, if I built it about 80 ounces

>3. How much more time to built a Shark in lieu of a regular

A bunch
>
>4. How many differnt wings ribs in a Shark 45?

All of them

Don't know but bet Lew had something to do with it. :)

Answer to question two;

is As much as it takes to make it fly!

Mine comes in at an average 61 ounces.

Well one of Lew's friends was flying one in a German wartime paint scheme! I bet that lost some points!

Ribs 1-4 did not taper in depth. Depth taper did not start until rib #5 on the original or in the Hobby Helpers plans. Hmmm, come to think of it I have all three sets of plans and there are differences between all of them. RSM's, Jetco's and Hobby Helpers.

I started a thread on this once before about the ribs and on the Jetco Shark the ribs taper in depth at the rear spar from the root out going spanwise and then get fatter toward the tip rib for some reason I just wish I could figure out why as I don't believe I got a single useful suggestion before.
If anyone out there has a set of actual Jetco kit Shark 45 ribs and they lay them all together with the trailing edges all in line like they would be on the model they will see what I mean.

Richard,
I don't know why those ribs you have are that way, and I don't know why they would be. I have a completed Shark on the wall uncovered and it doesn't seem to have a thicker trailing edge towards the tip.

Possibly Lew McFarland or Charlie Reeves could give you some answers. Their contacts are in the PAMPA guide, if you aren't a member maybe some of your buddies can help you get the numbers.

Not everyone frequents this board, so a direct contact with the principles responsible for the design will probably be the best approach.

Good luck,
Chris...

You guys disappoint me. I thought I'd be buried in correct answers.

The star decal was upside down on the "Navy" model.

>2. How much does a Shark 45 weigh?

57 ounces.

Lew says, 10%, I'd say that's conservative estimate. But Lew claims the resultant aircraft is 100% better. (I agree).

>4. How many different wings ribs in a Shark 45?

Eleven, and they are some the world's most complex ribs.

American Modeler, October 1961.

Dan McEntee must have been at work. He has all the model magazine collections and builds Sharks.

All I knew was AM-10-61!
I thought the paint scheme mess up might have been Charlie Reeves WW II german camo scheme.

Thanks Chris,
I am not saying the actual trailing edge is thicker just the ribs between just in front of the rear spars and trailing edge,I will take your advice and see if can contact Lew McFarland, as I have built the wing and the rear spar had to be cut with a slight bevel at the joint as it goes outwards at a slight angle, if I lay a straight edge on the top of the rear spar it has a gap in the middle top and bottom, but still runs parallel with the trailing edge outwards as you look straight down on the wing, it has no warps or dihedral or anhedral and was built square using the tabs that are on the ribs of the Jetco kit, I have never seen a wing built like this before, this may be a querk of the Jetco kit, I don't know I realise I may be making something out of nothing, but I am one of those people with an enquiring mind that just has to know why something is designed the way it is and has trouble just blindly building without knowing.Also maybe I am not explainig myself properly,I tried to post a couple of pics of the ribs that were cut from the original Jetco ribs but for some reason I couldn't.
I am a Pampa member so finding Lew's address shouldn't be a problem I just hope he doesn't think I am some kind of nutcase as I am sure several reading my post probly think I am.
