Crow add more stable to your landing and come in much slower speed without stalling.

Thanks,
Jeremy

That is smoking deal Habu Jason got.
Even 130 mph is too fast for Jason. He don't need 140mph. LOL

Glad to hear it. I am getting the HK Hawk and the new e-flite Phantom. I also have a 70mm Sapac Viper on 6S so I had to thin the fleet a little.

Glad he is enjoying it. When Gary and I radared the plane I got 128, 132, 135 & 139 or something close to that.

Peace

What a shame , glad you were able to bring it down in one piece .

If you don't mind me asking, was it just the ESC that went? Did the motor go too? What ESC was it? What batteries were you running?

Thanks!

Regards,
