 I have an IO-240 A in my TR-1 with a Prince P-Tip 62x68.   Full throttle give 2800 RPM and around 155 kts. 2500 RPM (7.5 psi fuel  pressure that according to engine manual should be 70%) give 135-140  kts.

Emne: VMax - KIS  TR-1

 

  Gentlemen

  

 I have a 2-place KIS TR-1 G-BZDR which currently has an IO-240 A1B fitted  (125HP) spinning an MT Variable pitch 3-blade prop.  The prop has been sent  for overhaul and the estimate is too expensive for me.  Therefore, I'm  looking at downgrading to a fixed-pitch 2-blade wooden prop.

  

 The manufacturer will optimise the prop design to suit my aircraft but  needs some information which I don't have and wondered if you guys could  help.  I used to cruise around at 145Kts at 75% power.  However, the  prop designer wants to know the theoretical max straight and level speed for the  aircraft at full throttle.  Anyone have any figures to hand for a TR-1 with  an IO-240?

  

 I'll be selling the old VP prop if anyone is interested, it's got 360 hours  since new but will need calendar overhaul.

  

 John

 Thank you for the information.  How long have you had the P-Tip prop?  Have you experienced any problems with it?  Have you got a wooden or carbon fibre prop?
