Wing Configuration; Muffler Selection; Required Items; Required Accessories - GREAT PLANES Piper j-3 cub Instruction Manual

For the best scale effect, an OS .48 Surpass 4-cycle is
ideal. For maximum aerobatics, an OS .70 Surpass 4-cycle
is all the power you will need.
This kit includes a Great Planes EM4070 engine mount
that fits most .40 - .60 2-cycle engines and most 40 - .70
4-cycle engines.

Wing Configuration

This kit includes everything you need to build either the
standard or the clipped wing for your Cub. Both versions fly
extremely well and are equally easy to construct. The
standard wing makes the Cub a real "Floater" giving you
plenty of time to think about your maneuvers. The clipped
wing allows things to happen a bit quicker. Snaps, rolls and
spins can be performed faster and more precisely. Either
way, the model flies much like the real plane.

Muffler Selection

If you install a 2-cycle engine, we recommend using a
muffler that can be partially enclosed inside the cowl. The
muffler shown in the instruction book photos is a Slimline
#3217 Pitts Style Muffler for OS MAX .61SF and .60FP
engines. If you use a OS .40SF or .46SF use a Slimline
#3218 Pitts Style Muffler or similar. Most standard mufflers
will require an extension to clear the fuselage sides.
