I checked both Helitec and Air Lloyd online and it seems to me that both of those companies are oriented more on turbine helicopters of other brands than Robinson. I have a feeling that they might take Robinson’s as a “weed” that is good only when there is nothing better to work on. I am looking for a company, which specializes on Robinsons and treat them as real helicopters with enough respect. But as I say, this is just a feeling based on their web presentation. Do you have your own, different experience Muermel?
