Maybe there’s a reason why this EMB 170/175 (I don’t have it) is the best selling addon at Simmarket atm even though it’s also sold at 6 other sites. I had the Virtualcol Embraer 190/195 in FSXSE and was very happy with it aswell as with a few other Virtualcol planes. Will buy it when it arrives to MSFS as it is Virtualcols next offering. This 170/175 seems to have alot of issues sofar compared to the 190/195 FSX/P3D version although the FMC is better but we will see what will happen in time for the 190/195.
I know nothing about the CJ4 mod mainly because it’s a business jet but if it means very deep systems I don’t think it is necessary for the base Virtualcol audience like myself. Virtualcol is/was very popular in FSX/P3D and if they can better their level from there just a little bit like better FMC I think they will keep their popularity.
