A mod aircraft called OPT S 88. Built with 270 of the finest parts, its root part is j.cockpitv2.
OPT S88: study and design coming from my last OPT Tanker K87. It begins with a J space plane cockpit followed by a J lab and a K section adapter. Then it’s Avatar fuel tanks because they hold much more fuel than the K tanks…
S for science, it comes with an OPT J lab and a lot of science stuff in the hold as 2 SC 9001 Jr, 4 mysterious goos, and a lot of sensors. SC 9001 are mounted on rail and all data are accessible via ladders.
88 for 88661L of liquid fuel (Nearly 14 Rockomax 64) that give to this SSTO a maxi range of 6000DV left in orbit, giving ability to join whatever planet in Kerbin system
Running on 4 OPT J61 Starwaster, 2 at the front, 2 at the rear and 4 MRS Nuke Quad engines, 2 at the front, 2 at the rear
The hold carries 4 big Mining drills, mounted on rails, 1 Convert o Tron 250 and 2 Small Ore tanks. A strong electric circuit, with big batteries from Batt Direct and numerous PB Nuk Thermoelectric generators allow drilling and converting 24H a day and 365 days a year….
8 6wheels main gears and 2 2wheels directional front gears allow to land this 60m long and 738T SSTO on any rough land provided your vertical speed at touch down is no more than 3m/s.
Powerful brakes and 4 repackable chutes allow very short landings. Landing legs at the rear allow vertical landings on low gravity planet and vernors engines situated under and over the cockpit help then to lower the plane to horizontal position as well as for take off.
Vernors are associated to SpaceY RCS thrusters to help maneuvers and docking.
the S88 is perfectly balanced in the whole flight enveloppe, dry and fueled COG being nearly at the same place and she climb easily to orbit, leaving 70% of fuel in 610 km orbit.
Take off weight 738T - Length 60m
Always open Cargo hold before using ladders.
Ladders allow leaving the plane, collecting science datas in hold and repacking the 4 drag chutes
Use robotic section to extend rails before using drills, scanner and Sc 9001.
Built in the SPH in KSP version 1.2.2.

Climb to orbit
Take off around 120m/s then pitch to 35°
At 10kms select pitch 15° and arrange your flight to be at Mach>4 passing 19kms to take advantage of J61 ramjet
You should be around Mach 5.5 at 27kms, pitch 8° or less, Apoapsis around 33kms
Light on Nukes between 25 and 27kms.
At 39kms J61 extinguish, so switch them off and switch off Air intakes too. Continue on Nukes
