Flight Time Calculation for Mikrokopters using Matlab

September 25th, 2010

Hi Guys!

This week Holger wrote a request in the Mikrokopter forum for a tool to calculate the flight time of a Mikrokopter based on basic parameters:

  • Thrust curve of a Motor (grams over current)
  • Number of Motors
  • Mikrokopter Weight without Lipo
  • Lipo Weight
  • Lipo Capacity
  • Payload
  • Losses
  • LipoFactor (g per mAh – typical 50-100 g/Ah) – Here is also a nice List from Nabazul from the MK-Forum

With this data it is possible to calculate the flight time.

Also I created very interesting plots of flight time over Lipo capacity and flight time over payload. (It would also be possible to creat a 3D plot with both parameters)

I decided to make the calculation with a little Matlab script (M-File) that you can download here.

Mounting the JETI Box Mini to the Graupner MX16s Transmitter

August 15th, 2010

Last week I received the JETI Box Mini from RC-easy. Perfect timing after the modification of my MX16s with the JETI 2.4GHz Transmitter.

So I mounted the JETI Box on my Transmitter and here are some pictures:

This is the JETI Box Mini:

Now I had to find a nice place where I can mount the Box to the MX16s. I decided to place the Box directly in the middle of the transmitter.

Then I put the signal wires of the JETI Box through the hole
