Bowker Aero Models 18" yak 54 short kits(UMX replacementairframe)

About a year ago I purchased a micro4site and was very disappointed with the flight performance of the model(weren't we all?) so I started working on my own design for the radio gear. This 18" yak was the end result, I also became very frustrated with the lack of performance I was getting out of the sub micro gear(I am much more of a 6g servo hacker a-10-9l foamie kinda guy) Also working with the gear takes more patience than I care to give to a foamie...

But after the recent success of selling off the 22" yak kits I had laying around for a the umx beast gear I decided that it would be worth it to try and offer a short kit of my 18" yak for the real ultra micro junkie's. This model is designed to run off the salvaged radio gear from a UMX Extra or UMX 4Site, It builds in between 1-1.2oz and has been flown on a tiger 1302 out runner on 1s with good success. The model fly's very well with little to no coupling of any kind.

Specs:
Wingspan: 18"
Length: aprox 20" (minus motor)
Flying weight: 1-1.2 oz
Radio gear used: ar6400 brick and 2x long throw linear servo's from eflight
Motor:flight UMX 4site/extra motor or 1s outrunner EG. Tiger 1302
Battery: 120 mah 1s lipo

What comes in the kit?
CnC precision cut and milled gediplac foam parts
all carbon fiber rods needed for construction and push rods
music wire for Z bends & heat shrink for making connections
The kit also comes with a cutting guide to install the eflight umx motor.

Why no control horns? I wanted to keep the cost of this model down as much as possible for you, Horns can be either salvaged from another crashed UMX airframe or you can make your own out of almost anything. I recently Used the plastic package from a hacker a-10-9l.

(please note this kit is designed for the UMX junkie's and not for the first time builders. This kit does not come with step by step build instructions of any kind, This thread is the instruction manual.)
