In other words, the proverbial "Brick-on-a-string"![/quote]

yep, thats about right.

If someone really wanted the 'plastic experience' get a late model PT-19, they actually fly pretty good (not as well as balsa) and pretty reasonable in price.

We get a lot of those around here, Helldrivers, trouble is they are on the roads!!

Not that bad but they are heavy and dont have much lift so.....

When ah say when my PT19 get's an outing in the Summer I was thinking of cling filming the wings.
Good, bad or rediculous idea?

I bet that would help them fly quite a bit better. I would like to see how that works as well

I have a ruff, old PT-19 that I redrilled the pushrod holes in elevator and bellcrank for more travel, added a blackwidow type engine, I plan to try a outside loop with it and/or inverted flight.

I'm sure covering the bottom would help some. I remember seeing in a magazine many years ago (when i was a kid) someone cutting flaps into the wing.

Looks like we have the same problem. This one is a # 1929. So what does this go to?

Thanks Mud.

Hi Mud and Joe,
The packing gives it away: it says "190" and it was used in some of those engines.
I am confused. According the the Dannels/Sitter book, Cox discontinued the use of this needle on April 17th, 1964.
Would it be posible for you to make a scan of that ECL, i would like to see what they say and how they look.

Regards
Thomas Pedersen
