This is my 1.30 scale version of the FT 3D.
It is made out of foamboard with wood bracing on the inside.
The bottom plate is entirly bass wood from the front until the tapering starts behind the ailerons.
During build before painting it red.
Plenty of space (for a squirrel) inside!
In comparison to the standard size FT3D.
Every meassurement is exactly 30% bigger then Josh's plans except the nose that I made 4cm longer.
The tail wheel is fixed, but it do taxi nicely on hard surface.
I have since the pictures was taken changed the nose like below, I felt that I did not have enough power, and blamed the large "waste" area the firewall created.
Some specs:
4 ParkZone servos (eBay)
NMT Prop Drive 35-36 910KV (HK)
Turnigy Plush 40A ESC (HK)
Master Airscrew 12x6 (Slightly too big but works nice)
Flying mostly with Zippy 2200 3s, but also tried 1800 and 5000 all works nice, 5000 makes the landings slightly hard and the 1800 feels more agile and acrobatic.
FrSky receiver
FlySky 9x with FrSky module.
The wood spaar inside the wings is quite long and goes to approx 20cm from the wingtips, I can hold the model in one wingtip without anything bending, nice and rigid.
I am having plans to maybe convert this one into glow, I have a GP40 that would fit nice here, but for now this is the nicest flying plane I built so I might just keep it electric.
I live in Dubai UAE, and foamboard of excellent quality can be purchased in Carrefour and Geant Supermatket for 14 Dirhams for a large sheet.
Flying one evening I got company of two birds who showed great interest in my creation, I hope you will too.

The total weight without battery is 1.4 kg.
I was also afraid of going tail heavy, and decided early to put servos and as much as possible in the front. It requires almost no down pressure in inverted so the weight distribution seams to be spot on.

I built a 120% version, and it comes in at 601g without the battery. If there's any interest, I could put together an article with downloadable plans.
