An overspeed can also caused by moving the prop lever forward to quickly. It doesn't matter whether the turbine is from Diemech or Lancair , both situations will occur. There are no automatic controls (ie. FADEC) to stop the above , you are the FADEC, so don't blame the arrow blame the Indian. During one of my takeoffs, I throttled up to 710 deg. C as indicated on the Electronics International ITT gauge, as a precautionary measure I downloaded the data from the TSLM, which showed 710 deg. C. Based on my experience, I will never buy a Lancair IVP turbine unless it has a TSLM.The TSLM allows a would be buyer to review the engine data which would show how the turbine has been treated. The TSLM benefits far outweigh the cost. Brian N76CU -------------------------------1149361665 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable
