No we do not. The trial was removed some time ago and we do not intend to bring it back.
If you buy VelociDrone and you cannot make it run, it doesn't run well on your hardware or you have issues then contact us immediately and we will be more than happy to assist fixing problems or if we can't fix it provide a refund.
Please check specifications carefully before buying, we have a minimum specification for a reason, if your PC is below this don't assume it may work, it is highly likely it won't.
