The pintle mount has already been successfully integrated and tested on Rudra.The pintel mounted MG requirement should be easy to install.
Regarding LUH..
As for the LUH, I expect that ground testing will begin in early 2014. Engine selection was an issue; however we have now identified the partner and are going ahead with techno-commercial negotiations. The complete design of the LUH has been frozen, the first Ground Test Vehicle (GTV) has just come off the jigs and the structure is completely ready. Manufacture of the rotor and transmission is underway and a lot of testing has to take place. We have to produce the specimens, do component testing, coupon testing and then the full fatigue testing as the rotor is very critical. The rotor has been cast and root segments have been made, the fatigue tests and specimen tests are commencing simultaneously. The gearbox castings are ready and getting machined. We have invested almost Rs 10 crore and set up a rapid prototyping facility.
We are looking at the LCH attaining Initial Operational Capability (IOC) by end 2014
Also regarding the ALH on Vikramaditya, there's a picture posted in this thread of the same. You might be interested to see
