RE: World Models 33% ultimate
Hi smokey.
I'm using 24" extension and it will reach the middle/back section of the canopy were i going to put my receiver.I also try the 36" extension and they are too long.In my local hobby shop or tower hobbies they only have 24" or 36".If you can find extension 28" long or 30" will be perfect.
And yes it come with everything you need,complete hardware,ball bearings control horns,pilot,wheels,fuel tank ,plastic spinner with aluminum back plate and extension servo arms with ball bearings.
happy landings.
Lito.
