Default Fuel

Do you have the ability to use MOGAS with your engine? Reason I ask is that Subaru engines have a history of stuck rings when running 100LL. If you have to use 100LL I recommend using Marvel Mystery Oil in the fuel. This helps keep the rings free. Youíll notice a stuck ring in the way the engine cranks when starting and when you turn over the engine by hand. I had one once and was able to free it up by removing a spark plug and dumping in MMO. I knew you arenít using a Subaru, but any auto engine uses tight tolerance on the rings. For anyone suggesting Decalin , I was using it as directed on every tank of fuel when I got my stuck ring.

Andy,

Thanks. I have been using MMO from just about hour one. I think Im using about 2 oz per 5 gal. I always use 92 Octange. I have not used 100LL yet, but of course I will when I go cross country. I did buy Decalin when I go beyond Phase 1....(hard to make a decision on MMO vs Decalin when experiences vary...) but I do like the MMO - but my experience is limited and arguably anecdotal on my part).

P.S. what CS hub are you using with Warp Drive blades?

Thanks Jim,

I am going to have to re-read up on that again soon. I have avoided Rule airspace during Phase 1 but of course that will happen in my near future.

It is hard to spec and source gears, and some will shed particles as they break in. Monitoring that is a really good idea. Particularly with a low volume gear like you have. If they are shedding particles continuously, ground the plane! It means they are wearing out and not in - a bad surface hardness and heat treatment. Cloudy oil is likely metal, but you need to catch it long before that.

Trust is ok, but please verify.
I agree. BTW , one of my favorite quotes from Ronald Regan, a great USA leader, Trust but verify.

Itís a 3 blade hub from italy called Quinti. Theyíre out of business. I believe that they also made 4 blade hubs. Both versions come up for sale occasionally. Thereís an electric adjustable prop from Australia that I saw at Oshkosh a couple of years ago that looked even better. Canít remember the name, Iíll try to find it.

Sounds like the Airmaster.

I have a couple friends using them, they really like the prop.

Default Yup

Itís the Airmaster from New Zealand. If I were looking for a replacement, thatís what I would be looking at.

Default airmaster

OK. That is good to know, thanks.

As much as I like the idea of a in flight variable pitch prop, I am going to try to keep things "as is" for a while to really get settled in with things the way they are. I have had my share of challenges, ( intercom, brake cylinder, fuel pump).....but fortunately, I think most of them have been fixed. At 24 hours now, I want to see some more relaxed flying before I change things up a bit.

It has been very rewarding though, and something I am very glad I did. And, yes, I do think this engine is a viable concept for this airframe....

Default hard climb info on PSRU

I did some hard climb tests today.

Normally in level cruise the engine/gearbox seems to settle in best at 4500RPM and depending on altitude about 25" of MAP. The gearbox stays about 190-195F

During hard climbout after take off at about 35" MAP and 4800rpm, about 1000FPM.....the gearbox rose slowly to about 225F when I had reached about 7000 ft. I had to level off to let it cool off. OAT was about 45F MSL and about 32F at 10K.

When I reduce the climb to about 500fpm the box stayed at about 200F.

I have not added my second blast tube to the top of the gearbox yet, but I absolutely will do that on the next rainy day I cannot fly.
