No this is not the extreme jets version. This is the jet legend version AKA global jet club viper.
It will take off fine on 400 foot runways that are grass if you either fly with a smoke system (I assume) or use the smoke tanks as fuel tanks. This will adjust the CG back for takeoff to keep the nose up on the grass take off. Otherwise the front gear sags due to the drag on the grass and your nose has a negative AOA.
I cant say that it WONT take off on that runway with the tanks all forward but mine with the CG back several inches uses up that runway a lot.
I did try once to take off with only the main front tank as I was out of fuel and only had enough to fuel that.
Despite being lighter, I had to aboart and it was almost a disaster, it would not rotate at its normal spot.
That is the only anecdotal evidence I have.
