I need to know the wing tube diameters and lengths for a couple of jets, and where would be the best place to buy some new ones.

Wild Hornet

Kangaroo

Boomerang Elan

Also is there a partial second tube behind the main tube on the boomerang Elan?

Years ago, I contacted Ray LaBonte (sp), who is a CARF dealer, and bought a nice thick walled replacement wing tube for my Kangaroo from him.
Hope that helps.

Hmmm....

Every time I've bought a different wing tube, the manufacturers' go by dimensions only. Never found a vendor who had the specific model information you seek? That information usually has to be gotten from the model manufacturer.

Same here for Roo and B XL rear tube.

Hi don’t know these guys can help but I have used them

Can't help with the Hornet or Roo, but you can try contacting Boomerang Jets ( https://www.boomerangrcjets.com ) for the Elan. If he doesn't have the tubes he should be able to point you in the right direction.

Hey Joe - for Kangaroo see manual page 30 - aluminum wing tube is 16 x 2 x 820 mm

old Elan manual if you need it - page 8 - only dimensions are for the aluminum dowels fwd & aft of wing tube

are the original sockets, carrier bushings not in the wings/fuse?

they will give you the od dimension you need, and the lengths can be measured and added to get a total for each. that just leaves having to decide on a wall thickness dimension.

I got both spars, I want a CF spar for the Roo and will need the Boomerang XL rear spar for another project.

Need measurements,? I got.

Thanks everyone for your input.
