VREF doesn’t price experimental and homebuilt aircraft at all — so most owners guess, or pay around $1,000 for a one-off manual appraisal. KitWorth gives you an honest estimated range in under a minute, free.
Pick your model and answer five questions. The range and every driver behind it update live — nothing is submitted until you ask for the full report.
Every driver behind your number, in plain language, before you touch a single control.
Engine hours since major overhaul (SMOH)
A fresh or zero-time engine carries a real premium. Most fours in this fleet run to roughly 2,000 hours before an overhaul is due, so hours climbing toward that number steadily discount the number — never the other way round.
Avionics tier
Steam gauges, a single glass display, or a full dual-screen IFR panel. After the airframe itself, the panel is usually the single biggest line item in what a buyer will pay.
Build year
Homebuilts don't age like certified aircraft — a well-kept older build isn't penalized for character. But an original-generation panel and older paint and interior do show up quietly in the number.
Condition
From a flying project that still needs finishing work to a hangar-queen showplane, condition is the widest single swing in the model — wider than any one spec choice.
Propeller
A constant-speed prop adds real capability over fixed-pitch — better climb, better cruise, a variable-pitch reserve for density altitude — and buyers pay for it, especially on the faster RVs.
The base range for each type, before your specific hours, avionics, condition, and prop move the number up or down.
Each type’s base range starts from broadly-known public market levels for typical examples of that model. The valuator above then applies five adjustments — engine hours since overhaul, avionics tier, build year, condition, and propeller — to land on your own aircraft’s range. These base ranges get revisited as new market data lands; nothing here is pulled from a live feed.
| Type | Base range |
|---|---|
| Sonex | $28,000 – $56,000 |
| Van's RV-4 | $40,000 – $70,000 |
| Van's RV-6 | $46,000 – $76,000 |
| Van's RV-12 | $62,000 – $102,000 |
| Zenith CH750 | $62,000 – $104,000 |
| Kitfox S7 | $68,000 – $112,000 |
| Van's RV-9 | $70,000 – $112,000 |
| Van's RV-7 | $85,000 – $140,000 |
| Van's RV-8 | $95,000 – $152,000 |
| Van's RV-14 | $150,000 – $232,000 |
| Sling TSi | $215,000 – $322,000 |
| Van's RV-10 | $220,000 – $345,000 |
These are directional base ranges built from broadly-known public market levels for each type — not live listings or a specific recent sale. Your own aircraft’s hours, avionics, build year, condition, and prop move you up or down from here in the valuator above.

No. The instant estimate is a model-based directional range built from broadly-known public market levels for your type, not a signed appraisal. For an insurance agreed-value figure or a loan, join early access to reserve the $79 comps report — it opens with launch — for supporting evidence in that conversation, or go straight to a licensed aircraft appraiser.
VREF prices certified, type-certificated aircraft. Every experimental and amateur-built airplane — RV, Sling, Sonex, Zenith, Lancair, Glasair, Kitfox, and the rest — falls outside its book, which is exactly why owners end up guessing or paying about $1,000 for a one-off manual appraisal.
A PDF with your aircraft's estimated range plus the recent comparable sales it's based on — for listing it, negotiating a purchase, or bringing to your insurer or appraiser as supporting evidence for an agreed-value figure. It's not a substitute for a licensed appraisal.
It keeps the evidence behind your agreed-value conversation current as your engine hours accrue and the market moves, instead of walking into a renewal with a number from three years ago.
