Christian Lucas never tells the truth. The 4140 wont be driving a 65 mm prop with 8 inches of pitch at 40,000 rpm. So far the 41 series powered boats on you tube are not fast at all!!!! plowing around in the water.

A 65mm prop with a tether boat pitch wont track straight either its going to prop walk ALOT

They guy is insane. Because again the motor is mechanically limited to 35,000 rpm specified directly at Lehner. Christian should stop lying to the hobbyist!!! HE hasn't run a boat in over 20 years so this drive is just a photo of nonsense the drive isnt going to go into anything animate.

Even as a boat motor it hasn't achieved anything extraordinary so its definitely a last choice for the air with its heavy self. at only a 41mm core.

The HK 4225 was more power dense at its weight.

SO.....

He has made some poor calculations for the forums.

If his motor doesnt go into syncloss why did he propose a sensored Castle XLX to you and ya boys until I told him at wot the castle is open loop Ralph?

He stopped posting that....and hit his ejector seat that he keeps handy for such corrections.

He tells the Gerd hes done talking every time he ask for verifiable data then pops up 60 days later back on the forum with more unverified 41 series wundermotor nonsense.

For whatever reason he seems to expect a cookie for incomplete ideas. if he want to show you a drive why not complete the assembly of the proposed drive versus showing you a phot0 of a pile of equipment that may or may not be related. The 3.8 to 1 Maxon planetary gearbox is lighter than the super chief and just as strong..

I dont get i.... around and around in circles.... its the same old things.

Its eazy to type hype.

Lehner 4125/4140 | Page 23 | RC-Network.de\

There is no video of these "runs"????

Anyone ready to actually take the mechanical measure and post the real rpm and torque outputs of the wundermotors?

Thank you for your time and patience,
Hubert
