Coop and Cameron, many thanks for your speedy reply. I have all the RSG Perspective+ hardware, and I use it on the Torquesim Cirrus aircraft, where despite the obvious incompatibility between the Perspective+ hardware, and the Perspective avionics in the Torquesim aircraft, it all works pretty well. The hardware also works pretty well with the native Laminar SR22, which does have Perspective+ avionics.
I still don't understand what the RSG software package offers, but I note it is based on the Torquesim G6 a/c, which retail customers don't have access to. I have had an email exchange with Jarrod at RSG about their Perspective+ software, but I'm still in the dark. The examples shown on their website show screens which are already provided by Torquesim in the G2/G3 models, so I have been unable to establish what value the RSG software provides over and above the excellent avionics functionality already provided by Torquesim. It causes me to think that if I could buy the Torquesim G6 aircraft, with the Perspective+ avionics, why would I need the RSG software at all? But then it seems that I can only get access to the Torquesim G6 a/c if I buy it through RSG with their software.
Looking at your replies, does that mean that although Torquesim have developed a G6 SR20/22, they have not made any attempt to upgrade the avionics modelling to reflect the Perspective+ hardware fitted to these a/c?
The RSG Perspective+ software offered on the RSG site offers a few purchasing options, one of which is "Perspective Plus software only - customer already has Torquesim G6 model" which is interesting, because it's not clear how anyone could already have the Torquesim G6 model because it is not readily available to retail customers. If one could buy the Torquesim G6 model, and it had Perpsective+ avionics in some form and was priced in line with other Torquesim products, I would gladly buy it.
The RSG website says in a footnote: "For customers that have the home/personal Torquesim G3 aircraft license - $1495 for the software plus $1145 to upgrade the aircraft model to the G6 plus a one time $199 setup fee for a total of $2839." This, I guess, suggests that the Torquesim G6 aircraft model is only available through RSG and for the hefty sum of $1145, and then to make that work at all you need the RSG avionics software at an additional cost of $1495. Given that the excellent Torquesim SR20 G2/G3 aircraft model, with very comprehensive Perspective avionics, is available all-up for $54.95, it is completely baffling to know how these two product offerings can be reconciled. For those wishing to use the Cirrus G6 with Perspective+ avionics on their home sim, I guess the only options are to stick with the Torquesim G2/G3 with Perspective avionics, which is an incredibly realistic product, or perhaps look at MS Flight Sim for their native SR22 which has Perspective+, combined with very clever, and free, updates to the NXi G1000 kit from Working Title.
So in summary, my understanding is that the Torquesim G6 aircraft model does exist but is not available to retail customers, and even if it was, it would not have functional Perspective+ avionics. That's really disappointing, because the Torquesim products are excellent, and good value for home sim users. The Cirrus SR20/22 is currently the best selling light aircraft in the world and perhaps if that trend continues, it will justify Torquesim refocusing efforts to update the existing, excellent models. Let me know if I have misunderstood the situation in any way, and thanks again for your help.
