Experimental Sling TSi

N84LD

Aircraft overview

This is an almost‑completed Sling TSi, four‑place, all‑metal, zero‑time Rotax 915iS turbocharged FADEC engine turning a DUC 4‑blade constant‑speed propeller. The airframe is also zero‑time, offering a clean slate for the first owner to complete the final steps, test fly, and place the aircraft into service.

Status and remaining tasks

The remaining work is administrative and commissioning: complete the weight and balance, perform the fuel flow test, conduct the first engine start and ground runs. Then schedule and complete the airworthiness inspection with the Charlotte FSDO. The aircraft is an excellent opportunity for a buyer who wants a top‑spec TSi without the multi‑year build, while still logging the final phase of the project.

Avionics and systems

The glass panel is centered on an Advanced Flight Systems AF‑6600 EFIS platform with full engine monitoring via SV‑EMS‑221, backed up by a Garmin G5 and TCW backup battery for redundant attitude and power. Radios and situational awareness include dual Trig comms, transponder with ADS‑B and weather, heated pitot with AOA, Dynon two‑axis autopilot, PS Engineering PMA450EX‑R audio panel/intercom, and a Pivot iPad mount on the right side ready for EFB use. The panel is pre‑wired with expansion for a WAAS GPS navigator such as the Garmin GNX 175, allowing a straightforward upgrade to full IFR capability.

Airframe, interior, and features

The TSi design provides gull‑wing doors with easy access to all four seats, a spacious four‑place cabin, excellent visibility through a large windscreen, dual sticks and rudder, and a well‑organized center console quadrant. Comfort and usability are enhanced by full ventilation and heat, red/white cabin lighting for night operations, steerable nosewheel (non castering, no differential braking needed), Matco double‑puck brakes, stainless braided fuel and oil lines, Intelligent Boost (Aerospace Innovations) wing‑root fuel boost pumps, and the NaviFlow firewall fuel manifold. The aircraft is parachute‑ready (hard points, cables and stowing compartment installed, parachute not installed), giving the next owner the option to add a whole‑airframe system.

Performance and finish

With the Rotax 915iS, the Sling TSi typically cruises in the 148–155 KTAS range at altitude, climbs at roughly 1,000+ fpm, carries about 51–52 gallons of fuel, and offers efficient 7.4–7.8 gph fuel burn at economy cruise with service ceilings into the mid‑teens and above. The aircraft is fully painted in Stewart Systems products over exterior stenciling by Evoke and cleared with ACME clear coat. Custom leather interior presents a high‑end, show‑quality aircraft. Built by a seasoned second‑time builder and EAA Technical Counselor, this TSi has been constructed with a “no shortcuts, no compromises, built right” philosophy, making it an outstanding value for a discerning buyer seeking a nearly new, high‑performance cross‑country machine.

Potential Buyer…

Knowledge of experimental aircraft is ideal.  Prefer the buyer be an active member of the EAA and their local EAA chapter. Buyer should be mechanically inclined and have a working understanding of building aircraft.
