Just do a search on ebay, or goole for "carbon fiber vinyl" - there are a ton of places selling it - I ordered a sample size one, just to see what it's like. I wanted to buy some 10 mil laminating film, to cover some flying wings I'm building - but it's expensive as heck!

It's not a particularly outrageously long flight time. We know the plane will easily cruise level
at 8A at 3S voltage. That means 8Ah worth of battery is good for a hour of flight and 10Ah
would be good for roughly 1:15 h. A 4S pack has 33% more total energy, so 10Ah at 4S should
add roughly another 25 minutes. You loose a little efficiency due to the added weight, but not
much (sink rate increases by the square root of the increase in wing loading).
In other words, I think they could easily have flown longer, especially with the airframe that clean.

Hello

IISI from switzerland

I use this system on all my multicopters, planes and helicopters.

It was perfekt, because it was my backup system for the OSD. And my OSD doesnīt work at this flight. So we can see the cappacity, AMP of motor.

At the end, the telemetrie systems shows empty - and when we look at the batteries, they are on 7% !!

nice telemetrie system !!

What kind of range do you get out of it.
Can't find anything about that on there website


Ok I found it it works on (433.92MHz)
So it will probably interfere with other HF systems.

Be careful with that vinyl it is very "heavy" a friend of mine ended up ripping it all off his wing due to weight increase
