new speeder
Hello speed friends,
here are some pictures of my new speed project.
A model with 2m span and 2m length, designed for up to 30 S LiPo with an APD regulator 20-300 HV and a Scorpion Powercroco 5050 motor , good for 20 KW. 100 % CFK
At the same time the 4.2 kg model flies with a Jet Cat 180 NX turbine and 3 liters of petroleum.
Have fun
Regards Michael

Update my winds and castle inverters are running more efficiently than Powercrocos 5040 speeds and YGE . My Eta is 96.14% My engine is only 448 grams and will peak 13 Kw .
U know me. He winds the old way I wind the new....
"I stall = working voltage / internal resistance
for 35V = 12500A
for 40.38V = 14421A
eta max according to the formula also used by ChristianL in the LMT thread (with the measured 2.8mOhm internal resistance):
calculated with 8.7A no-load current at 40.38 V = 95.1%."

Hubert
