Default freewing rebel V2 70mm jet

Does anyone have the Freewing rebel v2 70mm jet, and have flown it off a grass field. All the video's are showing a hard surface take off. I have the freewing f16 which is close to the same edf unit and motor and it will not
take off on a grass field

Don't have the Rebel but have other 70mm and 80mm edf's. Some are better than others on grass. A few things you're fighting to keep it from being a car:

1) The little wheels on these smaller edf's tend to grab causing excess drag. Also, the thinner the wheel, the better.
2). Length of grass. When our field is cut to 1.250 inches, I stand a good chance of rotating. If's even a 1/4 of inch higher, the odds go down exponentially
3). AOA- Depends. On a few, I've actually placed spacers under the nose retract to give the plane a positive AOA.
4). Lipo- Make sure you're using a 40C lipo or better. Need it to release those milliamps as fast as possible

Just my two cents as someone who's been in the same boat.

Good Luck,
