Practical, engineering-led guidance on selecting and sourcing propulsion for high-speed UAVs and target drones — written by the Sheng-Fang engineering team.
The JetCat P220-PRO-S2 and the SW220B both deliver 220 N class thrust at 2160 g installed — but 474 mm against 277.5 mm. Full length, weight, SFC and envelope comparison.
Read guide → Engine ComparisonIdentical 392 N thrust, 18.5% less complete-system mass. AMT Titan vs SW400Pro, plus the 784 N Nike against the SW800Pro and the Olympus HP against the SW240B.
Read guide → Engine ComparisonK210 vs SW220B at an identical 1740 g, K320 vs SW300B in the same 4.5 L envelope, and the 26 kgf bracket where Sheng-Fang has no engine to offer.
Read guide → After-Sales & Warranty25 cumulative running hours of warranty coverage, clear exclusions, and at-cost out-of-warranty repair with no labor markup — plus how to file a claim.
Read policy → Fuel & OperationsStandard fuel for model and small turbojets: kerosene (Jet A-1) with synthetic turbine oil. Ratios, diesel vs gasoline, storage, safety and winter notes.
