- maximum speed over 200Km/h. In the attached log file you can see, at line 587, H ground speed 53.06m/sec (191Km/h), M estimated airspeed 61.59m/sec (221Km/h). I have several flight logs with ground speed over 55m/sec
- acceleration at launch 0-100 <2.75sec. You can see it in the attached log file, considering that the plane is launched at line 370 and reaches 28.6m/sec (102Km/h) at line 381. Telemetry refresh is at 4Hz.
That would be cool... BTW that's about 150 MPH unless my cals are off. I've got an upgraded Stryker that might be able to give you a run for your money... If I had the jewels to give it a toss... (little out of practice on the fast ones).
Hi Chris,
in theory yes, but it is at the limits. Power consumption has peak to 70A and I use a 70 / 80A ESC. Battery are 2200mAh 4S 40 / 50C, so 88 / 110Ah. Motor is the weakest point, it is rated 700W and I ask >1000W.
Anyway autonomy is about 4' at high speed. I did a couple of flights at sustained speed without problems, but flying always at full throttle is not my style.
I recently fried a motor because I lost canopy in flight. Cooling was no more efficient, motor overheated, foam and tin solderings melted ! It was smoking like a real jet :D
I'm actually using a Newmotor. I'm considering to switch to a more powerful Newmotor.
As you can watch in those flight logs, altitude control is way more precise. But as side effect the plane is flying slower, because throttle is more accurate too. The WP sequence is inverted because it was North wind and those winds are strong : 30Km/h with gusts at 50Km/h. The plane was then fighting wind at low throttle, turning very wider then.
I'm still impressed how well wind estimation works, even with a rudderless plane. It is always facing the wind with ailerons yaw control, wow !
I was going to do some flights with full DR, but I fried the motor and probably the ESC again. Those high performance planes are so fragile ...

Congratulations. I have one of these FJ with NM ( Patrouille Suisse design). Maybe I try the AP on it one day after I saw this maybe sooner...

Congratulations.

Great Job!
just would like to inform that the Funjet is now equipped with a Newmotor 1110/2.5D.
Max speed clocked is 243Km/h.

I just wanted to point out that I published a video. It is in the head post.

I am very desparate to see the flight videos.
Thanks for your PM regarding Ardustation Help.
Thanks & Best Regards

thanks a lot for you kind words :)
For those flights I was still using r353, so no dead reckoning.
I tried DR in those flights, but the first release for altitude control only (r393).
