Yellow Jacket 3.5M RES Electric F5J and ALES

Description

THE HIGHER PERFORMANCE v2 WING-Increased speed performance offers a very wonderful flying model

The Yellow Jacket 3.5M RES is designed for primarily for electric launching, however bungee and gentle winch launches are acceptable with the V2 wing.  This is a very competitive model in F5J against all other build up “Ribbed” wing models.

The Standard Fuse is the CLM-Pro 130 which includes a Kevlar/Carbon Pod, Carbon Fiber Boom, and V-Mount.  The boom provided is a light weight 130 boom that we have specially made by CLM Pro for this model.  The standard boom is also available.

The servo tray provided mounts under the wing in order to leave the area under the hatch open.  KST Daviga DS213 or DS313 Digital servos fit the tray.  The under wing tray also has provision to secure the receiver.

Two motor mounts are available in for ether a 32mm or 34mm spinner.  The 34mm improves wire clearance using an outrunner motor

Information on the recommend motor etc can be found on the Building Tips page.

NOTE: You will see information on the tips page about flap installation.  I have designed a completely different 3.5 wing with flaps but I’m not ready to release it for website ordering.  Please inquire if interested.

Contents

The kit contains the materials and instructions to build the complete structure.  Adhesives, covering, and basic tools, electrical components are not included.  All laser cut parts are completely cut out and grouped so the builder does not have to cut parts from a sheet.  Parts are organized to simplify preparation and assembly.

Development

Version 2

Version 2 was in development for many months.  The goal of the V2 was to increase flying speed for faster launches and decents.  This wing was designed from ground up and features increased torsional and bending stiffness.  The wing is also more swept back (close to elliptical).  The mid and tip spar tubes have increase wall thickness and the main joiner diameter is also increased.  There is also strategic rib and reinforcements added in key areas.  Most of the minor weight increase was offset by using carbon fiber joiner tubes instead of brass.  The V2 Wing is also capable of bungee launching and by tapping up with a winch.   Full pedal and aggressive zooms off the end of the line are not recommended.

Version 1

This plane was developed in the fall of 2018 and tested all winter in AZ.  Several local club members built these and we flew at least 2 days a week.  This model was the plane of choice over AVA’s, Pulsar’s, Eagles and anything similar.  Our club has regular F5J contests with separate build ups scoring.   The number of pilots transitioning to build ups increase all winter.  I won this class with this model numerous times.  It is a winner!!!!
