coax.

project of mine.

hey brandon,
you should pop by the lab one day to see how it has evolved thus far.
Same stuff...different frame. And probably still a vibration mofo

[Brandon Chng]

yeah would love to pop by. maybe next week when i go on leave...

i wish i had time to do my new one though...

Question.

Why is it a three bladed coaxial??? Wouldnt a two bladed coaxial with FBL electronics do?


What is the flight duration???


Is it noisy than say a 600size electric heli???

[kiply]

What engines is the heli in the first two pics running? Petrol? Could be a stable platform for aerial photo or video

[kenjirol]

Engine looks like 1/5 gas buggy..(Petrol). My guess it should be a 26cc.
Looking at the tank, should go at least 30~40 mins.. Hope i'm right.

project of mine.

Test flight already ? Bro , can update the news ?

[Brandon Chng]

flew many times already. duration is approx 40mins. fly until shag. two bladed coax is not as easy as a three bladed one due to the weird geometry of passing links through the lower head to the upper swash plate.

How much and where to get this kit ?

How much and where to get this kit ?

Almost everything is custom machined

How much and where to get this kit ?

not that fun to fly leh...kinda boring one

all the differential pitch coaxial helis in the market including those from kamov and other full scale coaxials use three concentric shafts in total. i've got a design that uses only two shafts, is very compact and significantly simpler than the current version..
