I bought the Spark from harrymc if you all didn't know. I have just finished another project so i can get started on changing out the receiver and getting it ready to fly. As he stated the damage to the fuse was minor and very easy to repair. He did a great job on building it and i'm looking forward to the maiden. Can't promise this week but maybe next weekend if all goes well. Stay tuned!

Made the mistake of giving the wing to a custom bike/car painter. One of those friend of a friend situations. Still waiting for it.

I made the mistake of trying to paint it myself lol. Never used a spray gun before so it took lots of trial and error and wetsanding. Finally figured it out and I have the white done. Just need to do the red. I'm gonna take it to a guy that does this kind of stuff for the jet guys. If he's reasonable, I'd rather avoid doing it again. This is not easy work for a novice.

That looks pretty bright and shiny to me. I'm no Rembrandt with a paint gun so I thought it would save time having a pro do it. Guess i was wrong. I'll get her in the air some time in the near future, i hope!

With a little polishing the white came out like a bowl of milk. Very happy with the result, but I agree it may not have been worth all the time and mess.

Thanks Stone. I decided to let a pro finish it up. I might be converting this one to turbine

Looks great Raptor! This paint matching/airbrushing stuff is a real art.

That looks awesome. It's always better to let someone else do what they do best if you don't feel comfortable with the job at hand. Good luck keep us updated.

Finally got my Spark maidened on Sunday. I have been working on it since October. Stumax 100-45 with HET 700-83-1080, Kontronic ESC, not sure this is accurate but my WattsUp meter gave me 5200W, 140A on 10 S 60C GENS Ace 5300mA. Stu said he tested it with a 40C batteries and got 4500W. Tam Jets E retracts with brakes, BVM Brake Master cyl. JR servos on all flying surfaces. Never had an E ducted fan before, the last ducted fan flew was in the 80s an HOB F86 with an OS46DF. Needless to say scared the $#!+ out of me on the first flight, kept throtle between 50%-70% after it was off the ground...still too FAST! Didn't think I was able to land it, but after a few slow passes as slow as I dare too, it actually touch the ground with no drama at all. Second flight was much better, got to do a couple of full throttle low passes...WOOHOO!!! Still need to work on the landing, I think I can slow it dowm much more, but for now I will keep the speed up. The TamJets wheel brakes sure help slow this baby down the runway!

Congratulations,

You can slow down the spark to almost a crawl. If its balanced correctly it will practically land itself if you hold flare. Mine does not tip stall just sinks. Very predictable.

Good luck and enjoy.

congrats on your flights! the spark CG is very sensative. when set up correctly, the jet will land very slowly in high alpha. much slower then you'd expect.

cheers and happy flying.
