E-flite LR-1A Pogo 15e ARF Assembly Manual

Introduction

Congratulations on buying the LR-1A Pogo airplane. 

You have purchased what is arguably one of the most 

fun airplanes in the marketplace today. Originally 

designed as a fast sport flyer to bring an adrenaline 

rush to the mid to advanced pilots, the project quickly 

advanced to an even greater purpose. Working with 

legendary designer Jerry Small we developed the 

airplane into the standard for the upcoming Electric 

Formula One racing class from the NMPRA (National 

Miniature Pylon Racing Association).

Jerry designed a unique cowl system that includes all 

the graceful curves of the front of the fuselage into one 

piece that stretches back to the mid canopy point. This 

allows for very easy maintenance, easy mounting of 

equipment, and great cooling for the EP power system. 

We also elected to use mini servos throughout to save 

weight and expense; for the same reasons there is only 

one aileron servo.

Power for your airplane can be anything from our 

Power 15 motor on a 3S setup and a 10 x 10E prop 

(prop clearance limits anything longer) to a full blown 

race setup with our new Power 25 1250Kv on 4S and 

an 8 x 8E prop turning about 15,000 rpm. The sport 

setup will put you in the 80 mph range while the race 

setup has been clocked at about 115 mph. 

The airplane is a smooth flyer and goes exactly where 

you point it. Make sure all your friends pick up one of 

these kits then challenge each other to some impromptu 

racing for bragging rights at your local field. You’ll 

have a blast!
