Never mind that...I want to know how Tuan is able to have a wife, kids and a job, yet still have time for all this engineering and model work. It's all I can do to smuggle an hour in the garage here and there (and even then I'm usually still haunted), which is why the typical four-hour build takes me a month.

All this engineering work is really just reading from the experts on here.
I'm just trying to understand and picture all this stuff in my head.

I guess I fit the term keyboard commando pretty well , I get to sit in front of the computer all day long and sometimes need to look away from it and I just look to one of the other screens where Rcgroups, Autocad, Photoshop, and Excel are ALWAYS opened.

If I did really have all this time, the Vandal and the Aspire would be done by now. As well as X#2 and repairing the X#1 and Ceres, and getting the X21 programmed ...

Anyway, gotta escort my wife and kids to Disneyland now so I can earn a pass for this Sunday and next .

See ya!
Tuan

OK, Larry J says if I build this plane stock as it's intended, he's gonna give me a 2nd Aspire for free ... just to finish the build thread! How can I resist?

RDS will have to wait... I will try and finish her up next couple of days with little modification. .

Hope this post is not too early... nah... I go by Eastern Time anyhow

Man, I can't believe how fast you can get an Aspire together. So much is done for you already.

The hardest part was getting the clevis into the wing control surface horns. But with a decent pair of needle nose pliers and a large flat head screwdriver, I manage to not damage the horn fairings.

Now I just need to program in radio and flight comments to follow.

How did you mount the wing servos?

Hi Tom, On the wing tips I used the greening mounts, but the servos have ears removed. For flaps, they are stock, Greening mounts with ears on servo.

I used 30 minuted epoxy with cabosil. It is a tight fit that if I was not careful, I'd get epoxy all over the clevis when potting in the servos.

I have pictures posted.

Beginning of the thread. He reserved a couple post slots for the build.

It looks like I need 4.34 oz (123g) of lead for the nose weight.

With that, it will balance at 119mm per L. Jolly, though if I remember correctly, B. Clerx is a little less than that.

Man, does 4oz of lead sound like it's a lot?

I am flying with A123, 2300mAh cells though and they are lighter than any 5 cell 2300mAh pack so I guess the added lead makes up the diff.

Looking forward to flight testing Sunday!
Tuan

RTF weight with CG at 119mm is 2338g, 82.47ozz. A little off my initial estimate. At this weight wing loading is about 9.58oz/ ft2, which is comparable to a Perfect.

I know that this an Aspire thread but I used the Greening servo frames on my Shadow and XPlorer. Tonight I had to swap out a Hitec thin wing servo that was acting up. I used the install method recommended by Cody. I screwed the servo into the frame, placed the assembled servo/frame on top of a piece of packing tape. I then took an Exacto knife and cut away the tape, leaving the servo bottom covered and about .03"-.04" of tape over hanging onto the servo frame. I then used GOOP adhesive around the bottom of the frame and installed where I marked after dry fitting.

So tonight I backed out the 3 screws, unhooked the clevis and slipped a small flat blade screw driver under one of the servo's mounting tabs. It popped right out as clean as could be!
Install of the new servo was a snap!

I dremel the clevis little smaller, then it slips in quite normally.

It is important that you can easily remove linkage for a quick service between competition flights etc. The links provided with Aspire are good quality metal, but I have managed to bend flap links more than once

Finally got rolling on my Aspire - spent this afternoon building the skeg box. This will probably be the most time-consuming part of the build.

Going with JR 3421 servos on flaps and stab, and Airtronics 761z on ailerons and rudder.

Initial flight report

I am very impress with this plane. 3 hand tosses to trim her out and on 4th one I caught a small ground level bubble to make like 10 turns before landing her. In anyone else's hands they would have managed to ride that thermal for much longer. But I was getting nervous, because a football goal post was getting closer to her.

I had very little time on it today and was trimming in turbulent conditions, wind, I am guessing at least 10mph at times. What I noticed is that in the turns, the plane seems to have the least amount of sink rate of any plane I have ever flown. It's as if the plane was made for the banks.

It will climb out on the lightest of lift and signals lift extremely well. I know that is such an overly used statement, but rest assured the Aspire is all that. This plane will make you look like an expert. I might get mugged now releasing the secret.

I'm just 5-7, 140lbs and the Aspire is 3.7M 82oz... and if I can get this thing to thermal from a hand launch.....

I'll share another thing... late last night I was testing the ballast to see where it would cg. 1 of the slugs remained lodged in the ballast tube and was moving back and forth as I was flying it. I realized it was there when I took the hatch off turn turn the rx off and it was sitting in the front of the ballast tube.

I can't say how much it shifted the cg when the 2oz slug was at the front and then at the rear ballast tube. I'll find out later though. My CG is currently at 118mm.
