No, they won’t add spoilers becuse they didn’t exist in the real plane, you need to learn how to handle the plane as it is.
The key is very simple: low & slow.
Descend early, fly low, fly slow.
With BMEP in 90 and flying level the plane will slow down, if you miss-calculate you can always do a 360 turn as you slow down. Once you reach 174kts you can add flaps to flaps 20 and that will help you reduce speed to the 150-140 range. Let it slow until the final descent and as you descend to the runway you have flaps 30,40 and 50 plus the landing gear to introduce more drag and slow to Vref.
As you have noticed the DC6 is very difficult to slow down and because of that it is also very difficult to stall, you can just fly low and slow the approach and final descent and everything will be fine.
Modern SIDs and STARs are not for the DC6 if you fly on Vatsim make sure to use the proper aircraft equipment (/W in vpilot) and it is also useful to write “No RNAV capability” in te observations.
I fly all my flights on Vatsim, controllers are very very good to excellent and know exactly how to handle a DC6, a little help from the pilot is also appreciated like asking for vectors with a long final for the approach.
Final notice: If the plane is light is is even more difficult to slow it down, so plan carefully.
