Had no problem except that you needed strong legs to hold the beast at full power. A year ago I had a back operation and don't have those legs anymore. I could not even hold the brakes at 50% power. It seems the ratio between the master cylinder and the calipers were not correct. The calipers fitted are similar to a Cherokee 140. I got hold of a set from a Cherokee that was in a crash and made a new torque plate to carry one caliper in front and one at the back. Now the brakes feel normal and I have no problem holding 100% power. The pedal travel is +/- 15 mm from zero to max. The calipers the yak came with have 50 mm pistons and the extra ones I fitted are 44 mm. Andr Dawkins adawkins@iafrica.com South Africa.

Note there are two variants as per below. Chronographs => -1 = second hand operates with clock, stopwatch sub-dial 60 minutes => -1M = second hand operates with stopwatch, stopwatch sub-dial 30 minutes => mechanical Chronograph fitted with a heating element for very cold conditions => Pitot Heat switch controls the clock heater - although most have been disabled => performs a conventional Clock function as well as a Stopwatch and an Hour Recorder => outer scale is the main Clock & single sweep second hand => upper sub-dial is the Hour Recorder (HR) and the lower sub-dial is the Stopwatch function => two knobs are mounted to the outer bezel; Left function knob => normal position (IN) winds the mechanism => pull OUT & rotate hands to set time on Clock => push IN to change the setting selection interlink between Clock & Hour Recorder => each push moves a flag in the Hour Recorder dial - alternates Red, Red / White and White => corresponds to Set Clock & HR, Set Clock, Stop HR & Set Clock, Reset HR Right function knob => turn counter-clockwise to run mechanism, clockwise to stop => push knob to cycle Stopwatch function: Start Stop Reset Using the Chronograph => Right knob turn clockwise - ensure mechanism stopped => Left knob - wind mechanism spring until it begins to tighten => Left knob - push knob IN until White flag shows, pull OUT to set the correct time & push back IN => Red Flag - the White flag is replaced with Red flag indicating system fully engaged # turn Right knob counter-clockwise to run the Clock and the Hour Recorder # Stopwatch functions (push right knob IN) available => Red / White Flag appears on second push IN of Left knob # Hour Recorder stopped, main clock continues # Stopwatch functions still available => White Flag appears on third push IN of Left knob # Hour Recorder reset, main clock continues # Stopwatch functions still available Hope this helps.

I was a bit disappointed as I has just purchased the plane last year (from a crate from China) and assumed it was a new prop. Apparently on IRAN in China, they did replace the prop on retirement, but that was 2003. I am guessing with the comparatively low price of a standard CJ-prop, an overhaul is somewhat pointless. My question is as follows: What do I need to purchase/replace to meet the overhauled requirement? Any leads on where to get it and approx cost? Thanks, Phil Nicholson C-FEPN ________________________________ Message 7 _____________________________________ Time: 11:48:29 PM PST US Subject: Yak-List: Re: Russian time piece From: "Adrian Coop Cooper" Vic.
