Default 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

Should be good for at least 450 mph on the turbine.

The prop setups are a lot trickier, in both setup and flying.
30S is just nuts...I love it!

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%."
~powercroco~

Hubert

I'd really love for you to post the motor constants of your 5050.... to see if comes out any better.

Hubert
