I've been wondering for a while now what the purpose of that triangle shaped tubular frame on the wingtip of full scale aerobatic planes is for. Any help ?

Those tubes are reference markers. If the pilot wants to pull a 45 Degree Up/Downline he simply levels the wings and pulls up until the tubes are level. There are usually several different angles shown by the tubes. As the tubes line up with the horizon on the sides he or she can tell the angle of the plane.

Hope this explains them for ya, Phil (Mesa, AZ)

This is a picture from FS2002. It is in the Extra 300 on a 45 Degree upline, I am looking out at the left wing.

Hey Phil,
Looks more like a 43-44 degree upline he he
I wish I could go on a ride in one of those.

You can go for a ride in one of those!

Here is a link to a company that gives rides/flights in an Extra 300L. http://www.fightercombat.com/

You can even fly if you want!

I plan on doing it after summer.

The extra that I am working on will have the same paint job as there planes, a little different than the standard Patty Wagstaff scheme. Hopefully I can go there, about 5 minuites to there base of opperations, and take some photos of the plane first-hand before I start the covering job.

HOLY AMUSEMENT RIDE BAT MAN!!!!! We can go for a ride in a REAL 300!!! I hope there is something there for Bat Girl to do, cause I'm gonna be busy for a while!!!

There are many airports around the country where you can get rides or instruction in aerobatic planes. I got my instruction at Sussex airport in NJ, first in a 180hp decathlon then in a Pitts S2. Its a lot of fun.
