I have had mine to 17999 with no issue with stability.  Also recorded person=
al 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 en=
countered was poor engine cooling. Once past 13k in sustained climb the temp=
s 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 co=
urse. My engine at the time ran approx 195hp. =20
