[QUOTE=Guest;723254]Well, this afternoon Kev-o and I fired up the big Olympus.  Sal and his wife were there to see it as well.
The engine lit on the propane easier than any engine I've had and spooled up to running extremely quickly.  The first run left me with no throttle response which was entirely my fault.  Reflecting back, I had made a change to the glow plug voltage and RPM limits the other day and forgot to reteach the ECU.  (for those of you wondering, I lowered the max RPM limit for the first flights).
Anyway, I did a new teach on the ECU and went through the start sequence again.  Super easy start and it was running in about 40 seconds from the very beginning of the start sequence.  
I ran it up to about half throttle nice and slow, then up to full throttle, this engine nearly makes the ground shake!  Unbelievable power!
Back to idle and then a slam forward to full power.  From a dead idle to full power is less than 4 seconds (I counted one one thousand two one thousand three one thou.. and it was at full power).  Full power to idle is almost instant, less than 2 seconds, from half power on the engine to full throttle is about 1 second, definitely the fastest spooling engines on the market, even my 10 year old AMT Pegasus spools faster than many current engines.  
The sound of this engine in the firebird is amazing, like no other engine I've heard.  
Definitely makes you fully aware that you have an absolute monster on your hands and reminds you of the power you have in your left thumb.

Whether it's a 14lb thrust engine, or a 57lb thrust engine, you need to remember that throttle stick and respect the power that's there.  
I can't wait to fly the firebird now, but after running that engine, I will definitely make sure to realize where my left thumb is all the time!

From my first AMT I always thought, there is nothing like an AMT, I'm even further convinced now!

I've taken the jet to 2 events this year hoping to maiden it.

1. Princeton Spring event, unfortunately, although I loaded it and it was near ready, my thermocouple hadn't arrived (JMP uses a special thermocouple in the AMT's instead of the typical wire one's that many engines come with).

2. Jets Over Cayley in Cayley Alberta. Was ready to fly, but when we got to Cayley, I found that the runway, while very long, was only 50' wide and we had a cross wind. Couple that with a density altitude of around 6000 feet and it wasn't the time to maiden it.

I wanted to take it to Whidbey during their event to maiden. Maiden's were allowed after 5pm but at Whidbey the sun is right in your face by that time. So, the plan is maiden it on Thursday at Princeton as long as all the stars align and my butthole is puckered tightly enough LOL! This is the first jet I've owned where I kind of wish it wouldn't be a stupid idea to have a couple stiff drinks before the maiden haha!
Will let you know after the Princeton event how it goes!

Cool thanks for the update. I was away for a few weeks and thought maybe I missed something.

I know my Scorpion isnt as $$ and so forth as your bird, but it was definitley the most money I have tied up into one model (enough to make me slightly worried about dorking it, which I havent been before with any other jet). I thought I would have been nervous and was thinking of traveling to a bigger field, of having someone more experienced maiden it - but then I told myself its a proven design that should be more than able to handle my club field and went ahead. WHen I flew it I was fine.

I am sure you will be too, I mean you have enough experience and the plane is a proven design.

Hope everything works out weather wise and you get some flights in!

Sweetest turbine Ive ever flown, the Oly has no equal. Guaranteed to blow your mind in an airframe such as the Firebird. I have been flying this Pheonix UAV with a tweaked Oly, she just keeps accelerating so far 350 kts ++ on the auto pilot runs from about 6km out.
