"Off to Kentucky next weekend to pick up the SkyRanger and fly it back to California!"

Any updates?

I received my ELSA AWC today. The DAR-T with Function code 157 was Steven Huff. I will go to a Rainbow Aviation course soon to gain the ability to do my own condition inspections.

Mr. Huff works out of the Scottsdale FSDO and is available in the greater Phoenix area.

Went flying this morning.

WOT 5650 engine RPM.

Level flight, OAT 55F, Altitude 2000 MSL. IAS 130 Kts.

EGTs: 1185/1200. CHTs: 152/154. Oil temp: 158.

Oil: Sport plus 4

Coolant: Dex Cool 50/50

Fuel: 100LL with Decalin

Thanks for the advice.

Jim

Thanks. I'll check WOT engine RPM on the next flight.
There appears to be quite a bit to learn about this little engine.
Jim

I have to admit my ignorance.....again! Although I have significant experience operating Lycoming and Continental engines I have exactly 32 hours of Rotax 9 series experience. I find that my 2009 Gobosh 700 flies at about 100 knots, using 4.8 GPH, at about 4900 engine RPM. It is a comfortable ride a...

Thanks Paul, Going to switch this week. The mechanic that installed my new engine put in Evans because that was the only "approved" coolant in the POH of my 2009 SLSA Gobosh. It seems clear to me that, here in moderately warm Phoenix, the reduced thermal transfer capability of waterless co...

Thanks, I appreciate the help.

I have a new 912 ULS2-01 installed in my Gobosh. The mechanic who installed my engine used Evans Waterless coolant. I am going to drain it and fill with an approved coolant. 1. What is the optimum coolant? 2. Do modern coolants have surfactants? I've heard horror stories about how critical it is to ...

Well, SkyGeek says they have shipped my case of Sport plus 4. Pretty spendy, but at least I'll get it. The web site shows about 50 cases in stock.

Well, Calvert oil in Buckeye, Aircraft Spruce, Chief, and L.E.A.F. have all backordered AeroShell Sport Plus 4. they all said 4 to 8 weeks before it comes in.

SkyGeek said they had it in stock so I ordered a case. Hopefully they really had it.

Thank you. I always feel bad asking these types of questions because I know they've been asked before......often.
Right now my distributor, Aircraft Spruce, Chief, and others are out of stock re: Sport plus 4

My distributor in Buckeye AZ doesn't have Aeroshell Sport 4 in stock and is having trouble finding it right now.
I know it's been discussed, ad infinitum, but what is a good substitute? I use 100LL fuel.
Jim

Thanks for the reply Paul. For folks that are accustomed to Lycoming and Continental engines and 100LL fuel, this stuff can be.............interesting. I keep reading about how bad 100LL is for 9 series engines and many of the airframes; but then simultaneously read about how bad E10 is. Confusing d...

Hi, I'm trying to find out if E10 auto fuel is safe to use in the Gobosh. I've read the appropriate Rotax documentation and it is clear E10 is okay for this particular engine. I know the Gobosh has a composite tank. I'm trying to determine if this composite tank is adversely affected by E10. Thanks,...

Thanks. I appreciate the input,
Jim
