Lil Dublr (oz4919)

About this Plan

Lil Dublr. Small radio control model for sport and racing. Plan shows two different wing layouts.

Quote: "L'il Dublr by Brad Shepherd. This two-for-one half-A R/C model doubles as a speedy pylon racer or as a snappy sport flier. It's all in the choice of wing, and both types are included in the plan."

Quote: "The lil' Dublr was designed for maximum enjoyment of RC flying with a minimum of investment in money and building time. My goal was to have a versatile model that would fill the bill for those who like small models, have a limited budget, and enjoy different phases of flying RC. It can be built as a combination sportiaerobatic and racing model with just a little pre-planning, or, it can be built either way for fun flying or strictly racing. Study the plans and go over the building sequence before starting, and decide which type model you would like from your efforts.

A combination model can be built by switching a few plywood parts and building another wing and fuselage top to go over the second wing. The rudder push rod is locked in the equipment compartment when going to ailerons, and the correct propeller must be installed.

If there are no races to go to, bolt on the sport wing and enjoy the 'wild blue yonder'. If you are at a race and things are not going your way, bolt on the sport wing and forget about the races. If you would like to go full house with the big wing, I suggest the dihedral be reduced to 1/4 inch under each tip. Cut 1-1/4 inch off the lower part of D3 and it can be used as a tip jig if you build it this way.

The model is not a six-hour project where you build a box and bolt the wing on, but the little extra time and effort produces a fairly realistic model that you will enjoy.

SPORT WING: When constructing the sport version of the lil' Dublr, the two panels of the dihedral wing are built upside down over the plans. Pin top spars for each panel to plans, butting against each other at the centerline. Pin 3/16 x 3/4 LE in place for use as a jig. Glue ribs in place, pinning to spar and the TE jig..."
