I have had mine to 17999 with no issue with stability. Also recorded personal best ground speed of 278kts with an horrendous tailwind at that altitude. My climb rate was in the 250 range at that altitude. The biggest issue I encountered was poor engine cooling. Once past 13k in sustained climb the temps began to elevate because of higher deck angle and thinner air. Unless you are built real light I would say the practical ceiling is 15k with o2 of course. My engine at the time ran approx 195hp.

Angier,
A friend with a blue-printed 360 (200 hp?) decided to stop at about FL21
because aircraft stability became an issue.
Grayhawk
PS limiting factors at FL18 is proper O2 mask and supply, instrument
flight plan filed, proper transponder, etc............

Years ago I was told you
are there when the rate of climb drops to 100ft/min of less.
How high will
it go?
Frost bite might be the limiting
factor?
