Hi Ira, Don't you still need a tacho of some kind showing engine RPM (rather than prop RPM)? Cheers, Mark Read this topic online here: http://forums.matronics.com/viewtopic.php?p=150826#150826
Hi Terry, I suspect that in the UK we must have a tacho showing engine RPM. Can anyone confirm whether the PFA require that or not? Cheers, Mark Read this topic online here: http://forums.matronics.c
Hi Folks, Yes, it's true. I do manufacture the Soft Start Module (SSM). Although I designed/developed/tested/manufacture the device, it's not my idea. Conrad told me how it should operate and I "made
Sorry, I don't know anything about the LAA's thoughts/policy re the SSM. If anyone knows, it will be Conrad. Cheers, Mark Read this topic online here: http://forums.matronics.com/viewtopic.php?p=1710
Folks, Although it is neither an AOA system or a stall warner, my SmartASS unit (www.smartavionics.com) will help the pilot to maintain a safe margin of speed above the stall on approach. I sincerely

Folks, I have been busy. You can now see a demo video of the SmartASS being used on approach. It's simulated, but real. By that I mean that the video has been captured from a computer flight simulato
Folks, What follows is a general comment and is not related to any specific failure of an electric VP prop system. Jos is right to question the quality of the electrics (motor/switches/diodes/wiring,

Hi, I have nothing to say re the suitability of the microswitches/diodes used by Woodcomp in the SR3000. However, from what I know about the characteristics of the scimitar bladed SR3000 fitted with

Howdy folks, Cranking the engine and then turning the ignition on is not equivalent to how the Soft Start module functions. The purpose of the SSM is to keep the ignition retarded while the starter i
Hi Svein, How about checking the ignition pickup gaps. Perhaps, they are wide enough to make the ignition unreliable at very low RPM (i.e. when starting). Cheers, Mark Read this topic online here: ht
Hi Karl, Sorry, I can't remember what the min/max gaps should be and I no longer own a Rotax engine but I'm sure someone here can advise you (and the numbers are in the manual). Cheers, Mark Read thi

Hi, I have an Arplast PV50 VP prop (narrow blades) that is surplus to requirements. It has done 410 hours and is in basically sound condition. Some minor dings on the blades but nothing major. It has
