Hello,
Regarding the stall speed of the Sonerai 2,
On the Monnett plans or documentation I found the value of 72 km/h for the stall speed (39 kts, 45 MPH) But according to different sources found on the internet, this value is much higher... up to 100km/h (54kts, 62mph) at 550kg (1200lbs) for one source.
Of course they are indicated speeds, whose value is not very precise because of the pitot tube indidence and anemometer calibration error .
Notice to all SONERAI 2 pilots,
Can you give me your stall speeds read on the anemometer and for what weight?
Why this research?
Well, I plan to register a Sonerai 2 in Ultralight (in France) but I must prove that it is less than 70km/h (38kts, 44mph), which is not the basis of the basis but I would like to see the Feasibility with VG's or a mixing of flaps in flaperons.
if the speed gap was low, knowing that in reasonable way I can limit the maximum weight to 450kg (990 lbs) which can help.
Obviously if the real stall speed was higher than 80km/h (45kts, 50mph) there is very little chance that reaching 70km/h even with flaperons.
Thank you in advance for your help or your advice
Sincerely
