It has been said before that the Large Hawk has troubble retracting the gear because of not enough power in the retracts/ air cylinders.
In the video from Florida Jets above, the gear does not retract so Ali eventually has to roll it inverted to get the gear in.
No doubt it should not not be this way, but the question to Anton/ SM is: Are there any upgrades to the gear on the current planes being built and shipped??

As you know, I have one on order, and would really not be happy if I have to pull tricks to get the gear to retract on every flight[X(]
