This LD-3420 was delivered after the introduction of the four-digit serials as LD-3420/N6925E through Shannon on 07 June 1984. It was sold in the huge Mentor auction on 26 March 2018 and went Stateside as N87GR.

Delivered on 21 April 1978 through Shannon as N4872M/B403, later received serial LD-3403. Auctioned on 26 March 2018 and went to the USA with many others, taking up its original registration N4872M again.

Not in Team Jupiter colours this time, it went on to become LL-0113 later.

This Turbo Mentor was delivered on 19 May 1978 as N4881M/B407, was re-registered as LD-3407 and stored in 2018. It was sold during an auction on 26 March 2018 to a civil owner in the USA and was registered as N15GR on 24 July 2018.

This Woong Bee LD-0115 was quite new back in 2013 with Skadron Pendidikan 102. It was loaned by Team Jupiter and is still used by them, albeit with a different serial, namely LL-0115.

Indonesia was the 1st export customer of the Korean built KT-1 and initially received 17 units (serialled LD-0101 through LD-0117) and assigned to Training Squadron 102 in Yogyakarta. LD-0105 still wears the big black serials instead of "TNI-AU" letters later applied. By now, all TNI-AU KT-1's are assigned to the Jupiter Aerobatic Team, and have been re-serialled to LL-01XX (LD-0105 shown here became LL-0105). As of December 2021, at least two additional KT-1's are about to join the fleet to make up for the few aircraft lost during accidents. They will become LL-0118 and LL-0119.

Indonesia's Air Force TNI-AU was the 1st export customer of the Korean built KT-1 and received 17 units. A few have been lost unfortunately, including the one pictured here on December 7, 2020 during approach to Adisutjipto Air Base in Yogjakarta (where the fleet is based). Apparently, Indonesia ordered three more KT-1's in 2018. The first a/c, delivered as from 2006, wore a light grey paint, but soon afterwards the TNI-AU started to apply this red/white livery with big black registration letters. All TNI-AU KT-1's are now assigned to the Jupiter Aerobatic Team.

LD stands for "Latih Dasar" and means "Basic Trainer", even though the indonesian AF used the 20+ Turbo Mentors in it's inventory as advanced trainers. The type was introduced to the TNI-AU in 1978 and served till 2015/2016, when it was replaced by Grob 120 TP aircraft.
