Default "experimental prototype"


Another of my project I have built some years back as an experiment before building the same but much larger jet turbine powered,

"Touch of Magenta". To make sure it would fly, the safest way was building simple foamy test bed, powered by 3.8 Kw/10S unit with

some 1 to 1.5 ratio size and power wise, comparing to my turbine version. Being own design scratch build, the C of G is always the main

concern with models like this so it is better to be safe than sorry. Simple 2ch. Elevon controls with no Rudder, only extra channel for the

nose steering makes this 7 feet long model run like on rails. The 90mm multi bladed fan with specially designed thrust tube is giving it the best

static/dynamic thrust after bit of experimenting. 4-5Ah packs are used to give me 3-4 min flight times. Not the fastest, but confortably

reaching 200km/h in level flight which is more than realistic scale-wise for such a large sleek air frame. Few pics flying today in perfect calm.
