Status: offline I have read through this thread and would like to reopen it.

I am researching the BN 120 and would like to know what new modifications current builders/flyers are making to this plane.


I have the new arf, but made some modifications to it after talking to Morris and several people here in R/C universe.
Here are the Modifications:

Elevator
I build a new elevator and stab using the plans. I moved the hinge line 1" forward from where it is indicated on the plans and added another 1" to the trailing edge of the elevator. I modified the Rudder relief angles of the elevator to achieve a full 45 degrees of deflection to each side. I also added double beveled edges at the hinge line

Rudder:
I added 1 1/2" to the trailing edge. I also added double beveled edges at the hinge line

I made no changes to the wing or ailerons.

When discussing this plane with (Robert?) at Morris Hobbies, We talked about using this plane as a sport flyer and a entry level 3-D Aerobatics plane. I chose a Saito 1.50 with an 18-5 Zinger Pro Prop 15% - 18% Wild Cat 2-4 stroke fuel

The plane is not quite finished yet, so I am not sure how it flys yet, but I'll keep you posted
