Dear Brian,
I have a PV50 and also would like to receive any updates from Arplast. I also am the only winner of the SUN 100 (2002) that did it with a PV50. My Pulsar is not really fast because it was not built for speed. Rick does not have a nose wheel and is still the fastest that I have seen. Jerry has such a small nose wheel/pant and the Aero Design small nose wheel strut that his Pulsar is also faster then mine. In the SUN 100 race in 2003 I was trying to catch Rick and averaged 160 mph from a dead stop over the 82 NM closed course. Rick passed me before the first turn and won the under 125 hp class with an average speed of 178 mph. I suspect that since I was second and Rick passed me on the first leg that he was just cruising the last two legs.
Tom.

Hi Barry,
I received a brief reply overnight. Arplast now say that there is no limited life.
Laetitia, whom I have spoken to briefly in the past, provided some additional maintenance information. Unfortunately it is a .jpg copy and in French, so it is not easy to translate automatically. As far as I can determine there is nothing particularly new about the information, so provided we continue to grease the bearings and lead screw it should all be OK.
I will send the .jpg information separately. Maybe your French language skills are better than mine, so if you see anything useful perhaps you can advise.
Brian.

I’d be interested to hear what Arplast have to say about maintenance of an ‘old’ PV50. Mine is getting on for 15 years old and must have around 600 hours on it now. No problems at all with it since all the early problems were ironed out (mine was a very early model) but it would be nice to hear what they have to say. The UK distributer closed down a few years ago so there is no direct support (that I know of) in the UK.

Hi Bill,
I also have the PV50. It's done about 460 hours now [12 years old] and I have been wondering about the life. I remember reading in some of the early Arplast documentation [ - - very limited] that the nominal life was 500 hours. It's a great prop, and I agree about the performance improvements being able to adjust the pitch in flight.
Some time ago I also had a motor failure. The motor just wouldn't start and move in one direction. I talked to Arplast and they sold me an "improved" motor. No troubles since. Each annual I open the prop hub, clean out any hardened grease and re-grease. In fact I did that yesterday, and checked the operation. All is OK. The new motor was supplied with the lead screw and bearing. The old bearing was a bit rough and lumpy too. In the meantime I had purchased a replacement bearing locally anyhow. It is a standard [metric] size and was easy to find.
I can't imagine the lead screw stripping. It is fairly substantial.
I was about to write an email to Arplast to ask about the life, and any particular maintenance that might be necessary. If I need to think about a new prop I would still think seriously about the Arplast again.

In past years I've had that happen one other time, plus two failed electric pitch motors. Fortuntately the failure mode is always the same - pitch is stuck where you last had it. So as long as pitch range is limited to safe flight you're okay, but it does make the cross country longer when top speed is 110mph due to engine rpm.

Hi Tom,
I remember reading about how fast Rick was flying, and I compared his speed to my test flying period. Flat out I managed to achieve 146 knots, or 168 mph. That was at about 2000 ft, 5400rpm with the pitch adjusted to maintain that speed. I don't know that I would like to try to maintain that during the course of a 100 mile race. Also I remember that Rick removed all surplus weight from his plane before the races so he would be a deal lighter than mine in standard trim. In fact, mine turned out to be somewhat heavier than many Pulsars, probably because I was a bit generous in adding glass and resin here and there, and adding a few essential modifications.
Regards,
Brian

If I remember correctly Bernard Wilder holds the top speed in a Pulsar all be it when he lost it in cloud and came diveing out the bottom at about 300 mph luckilly all still in tacked.
Maybe if he sees this he will confirm the details.
