Extra 300 build.

Memories, memories, memories There is a very informative and ongoing thread on the Goldberg Extra 300 in the Kit Building forum that gives some very good tips and advice for building the Extra, so do yourself a favour and have both a look and a read.

Thanks. Will do.

I know there might be several threads and I do apologize for making another. I didn't want to use someone's else's thread on my personal build. I did read on the very long thread (pages) Extra 300 build. Very informative. Thank you forum.

One important thing we have learnt about the Extra's fuse is that it is a very good idea to keep the cutouts in the fuse just forward of the main l/ gear in place and to add an additional ply doubler from the wing leading edge cutout right back to the bulkhead forward of the l/ gear location if a heavier and more powerful engine than the .61 size the model was designed for is used, especially during those unscheduled hard landings as this area is prone to breaking. Seems to be the only weak link in the model.

Thanks....I look into strengthening those areas. I have one more in the box brand new, just in case I get bored.

Wow, someone with more then one of the kits on hand. Back when they were still being cut I used to keep a couple on hand. PLEASE, make sure you draw out a good set of templates of every part in the plane so you can share. I do have a set of templates one of the guys drew for me but they are a little rough, useable but rough. I have shared them several times just to keep this plane alive, it's that good.
When Tower/Great Planes bought the rights to it there was a lot of speculation about upgrades and laser cutting, I figured they would drop the kit and was proven correct. Templates keep it going. Sure wish GP would have made it as a laser cut but the die cut kit fits very well.

I just keep my fingers and toes crossed while hoping that one of these days they ( Tower/ Great Planes ) will have a change of heart and make a limited production run of it.

Tower/Great Planes has their own version of the Extra. I doubt they will produce the Goldberg version again, it would be like competing with yourself, just my 2 cents. It is an awesome flyer though.

I also have GP Extra 300 in the box, but the WS is only 58".

I do believe the model he was referring to is the Great Planes .60 size 64" span Extra 300.

Hey Hutch66,

Is that a YS91 in the pictures posted above? If it's any bigger than that, you may want to reinforce your wing attachment points.................. Keep up the great work.

Take care,
David

Don't apologize for creating "another thread"  The more info the better, and sometimes having a couple threads makes things more readable than adding to another thread.
