.rajul,That is really a nice looking box.
I have a SIG box coming,the big one like you have.
I like the 1/4 ply uprights to support the plane.
Everyone TH sells uses the 1/8th balsa and it's not very strong so I never bothered to install it.
I have a couple of questions.
What pump is that and who sells it?
Doesn't look like anything I saw in TH catalog.
The removable carry bar is your own mod?.
Very nice setup.
I guess you have access to a band saw?.
$22.00 differance between the TH box and the SIG and you have all good quality materials.
The pictures show the quality of the SIG box.
Thanks for posting themm
