@Dillinger:
I remembered that you asked about robots for spraying RAM paints on the thread"AMCA Project heading LCA Direction",Guess what? we are using Robots for spraying RAM on LCA itself.
and We now also have a full-fledge facilty to calculate RCS of 1:1 model at NAL.

How will we measure the RCS of the full product in order to ensure that the final construction complied with the scale model completely?
How will we get Repair Verification Radar (RVR) test sets in order to verify the RCS of the aircraft after performing repairs?
It seems that in the last decade many specialized facilities and technical infra enclaves have popped up which were unavailable during the Tejas days.
But darned I'll be- your posts always reveal something new every time.

Any comments on this? What other new test facilities have come up. I believe a turbine engine test facility was on the cards? Have such RAM coating machines been integrated into the production line or are they isolated to the prototype construction usage due to lack of numbers of said machines, pessimistically assuming there is a lack in numbers.
After all of this we are still left with engine problems and as @sancho sir stated perhaps even basic design problems leading to issue of drag and unsatisfactory AOA- or is that ONLY because of an under powered engine on the LCA?

Nice to know.
But be careful mate with what you share here. Don't get yourself in any trouble.

http://www.indiastrategic.in/topstories1976_LCA_may_get_IOC_soon.htm
Air Cmde K.A. Muthana, VSM, Programme Director (Flight Test) piloted the aircraft on its maiden flight on March 31 at supersonic speeds and a 20 degree angle of attack, which is the current maximum limit cleared by its design.
Designed by DRDO’s Aeronautics Development Agency (ADA), the tail-less delta-wing aircraft was accepted by the Indian Air Force (IAF) in March 2011 although its IOC has been delayed for long. Recently, Defence Minister AK Antony also expressed displeasure over the delay.
The aircraft is built by HAL. After the successful flight test of the 8th aircraft, HAL Chairman Dr. RK Tyagi said that “the performance of the aircraft was flawless.”
An HAL statement said that the aircraft underwent a series of rigorous checks by the certifying and inspecting agencies during the last fortnight with a few taxi checks to assess its performance.
“The last aircraft in the Limited Series Production programme of LCA-Tejas (LSP-08) took off on its maiden flight here today from HAL airport. The aircraft was flown covering a flight envelope at supersonic speeds and at an angle of attack of 20 degrees which is the current maximum limit cleared by design. With this, the Initial Operation Clearance (IOC) for the aircraft can be expected soon.”
It should take a year or so to get the Final Operational Clearance (FOC), after which the aircraft would be inducted into IAF squadrons.
“The aircraft with a build standard akin to the Initial Operation Clearance standard underwent series of rigorous checks by the certifying and inspecting agencies during the last fortnight with a few taxi checks to assess the aircraft performance. The flight clearance by the certifying agencies was accorded today (March 31) after ensuring that all the aircraft systems were functioning satisfactorily on ground.
“Till now aircraft normally undergo high speed taxy trials prior to the first flight. However, with the confidence gained by the flight crew and the certifying agencies during the build and ground checks a decision was taken to proceed with first flight without going through a separate high speed taxi trial."
The latest LCA carried several modifications relating to fuel, environment condition, electrical and avionics based on the feedback from the 7 earlier aircraft. The modified systems performed well.
Described as a Mig 21++ by former Chief of Air Staff PV Naik, the LCA uses a lot of light composite materials. Its initial lot is being powered by GE 404 engines, but under an agreement signed last year, HAL is acquiring 99 GE 414 engines – the same which power the US Navy’s Boeing Super Hornet F/A 18 aircraft – for the later versions.
IAF and the Indian Navy have a projected requirement of about 200 LCAs, officially designated Tejas. The long delay in the programme however may change the requirements as technology now changes by the day and it would be difficult to incorporate the emerging, newer hi- tech features.
However, Tejas indeed has several modular features. Besides the engine from the US, there are some 360 Line Replaceable Units (LRUs), out of which 168 are imported mostly from France, Germany, UK and Israel with the rest made in India.
According to DRDO Chief, Dr VK Saraswat, the effort is to indigenise wherever possible and the Indian industry, both public and private sector, is being encouraged to come up with exacting solutions, or drop-in replacements, to meet the requirements.
The indigenisation will be good for the country on the one hand and help boost the economy through the developing defence-industrial sector, he told India Strategic in an interview.
IAF will deploy the aircraft in southern India.

Here are some possible load configs for IAFs LCA:
(Interception, CAP, CAS, heavy strikes)
For the record, possible N-LCA configs:

I don't understand why only one sortie for lsp8 in nearly one month.

Tejas not suffering delays not due to technical deficiency
Recent media reports has been claiming technical deficiency of Tejas, sources close to idrw.org and some close to the program have informed that Tejas program is not suffering from technical deficiency has reported, other sources somewhat confirmed that “Go slow “approach has been adopted on AMCA case but work is moving ahead by small group of scientist has most of focus is still on achieving IOC-2 and to get Tejas MK-II in air by 2015.
Claims of Tejas requiring hours or days of technical checks after each flight was also dismissed by our sources. “It has to happen when TD-1 and TD-2 has to fly but not now” claimed a source, “same aircrafts are available for flights even on same day if they are any schedule test flights “. Aircrafts have successfully operated outside HAL complex (Bangalore) many times for various trials with minimum Ground crew “said same source.
Another source claimed “Tejas is suffering delays due to inexperience of ADA and HAL in getting things done in time frame and its failure to move production of various components from lab to production house”. But there is no denying that HAL is also guilty for not able to put the aircraft in production due to its own deficiency and it lack of trained manpower It takes HAL 9 to 12 months to assemble and make one Tejas aircraft airworthy, HAL is trying to bring it down immediately to 3 months and by 2015 HAL plans to cut it to 1.5 months for each aircraft.
IAF have ordered 40 Tejas MK-1, first 20 Tejas MK-1 will be based on IOC-2 Configuration and next batch will be based on Tejas MK-1 FOC configuration, ADA will be putting together Tejas MK-2 for its first flight by early 2015. In next Two or three years Tejas program has to achieve IOC-2, FOC for Tejas MK-1 and first flight of Tejas MK-2 and its production and certification , Refocus will also be back on testing of Naval Tejas . This has lead to “Go slow “approach on AMCA. And first flight of AMCA will also suffer delays due to this and first flight mostly likely will happen in 2020 or later as per sources.
