Nothing fancy, but the first FF model I have built in more than 20 years
Actually started it more than 30 years ago, about time I completed it
Held the camera in one hand, threw the model then took the pictures.

And not a picture, but here is a video:

Next up - a rubber model of some kind.

You can buy the kit from Campbell's, or the plans can be found on here:

And the article as well:
http://www.rcgroups.com/forums/showp...postcount=6270

(I asked in that thread since I had long since lost my original copy)

Weight came out close to the article, 37 grams versus the suggested 1.25 ounces = 35.4 grams. Finish is 3 coats of Minwax Polycrylic, put on then wiped off with a blue lintfree "shop" towel.
Much nicer to deal with than dope, but seals so well it makes it a bit harder to do the "breathe on it and twist" method of making adjustments.
You make an adjustment and then over the course of a few flights it would go back to neutral. I ended up having to make little cuts in the surfaces and glue the adjustment in.

The model trimmed out very easily, I was surprised that I could still throw it and get it trimmed. .
I do think it might be a bit nose heavy as it tends to want to loop in the throw, but the transition is very predictable as it is set right now.

The weather that day was perfect, almost no drift and the thermals were not so strong as to cause it to fly away.
Longest flight was 3:20, a couple just over 2: and a few more at ~1:30. Then a whole bunch at 30 - 45 seconds depending on how well the throw and transition went.

Sort of neat to watch in a thermal, the plane kind of rolls a bit from side to side when it is in lift, probably from the turbulence.

Spent most of the day doing it, even though I had a few high$ sailplanes sitting in the pits.
I was sore for a week after all that chucking!
Now the weather has gone bad and I might not get anther chance till spring

Freeflight power model.

Freeflight power model after 3 or 4 months of work.

65in span, Rossi 15 on hard tank pressure, flood off and brake to stop it. Carbon prop.
Auto rudder and variable incidence tailplane and DT activated by Seelig timer.

Pics tell the best story I guess.

We also need to know if it is already trimmed so that it is safe to get out of the house...

Just relax "perttime". Mine don't crash, they are built to fly. I truly have never crashed one like this. They are easy to trim, and beautiful to fly.

"flight99". Your right re. the flower pots. "The Boss" just ripped some old stuff out a couple of days ago. New pretty things going in on the weekend she tells me.

Whew...

I've never actually seen one fly. But, somehow, I've gathered that the results can be spectacular if the wrong things go wrong with a power model.

I've seen a few go off track and get quite scary, but most locked-down models like Gossie's masterpiece there are quite predictable. Worst I've seen a locked-down do is fold a wing and tumble into the ground. Scary moments do happen, but fortunately aren't that common.

I've seen a lot of RC models get into trouble. Compared to them, FF is quite safe, even in F1C where you're right on the edge.

Thanks for the compliment Josh, but this power model of mine is not really locked down as such.
Locked down to me means wing and tail and fin/rudder do not move. We often lock down the stab. in a flyoff so the DT does not work so as the flight goes as long as possible.

This model has a moving rudder about 1/2 the area of the fin that is pretty much straight as the model is climbing vertically under power, then as the engine is shut off via the timer using flood off and a brake, the rudder at the same time moves about 3/16th to the right kicking the model off from the vertical.
A couple of seconds later the stab. raises about 1/8th at the rear to put the model into glide mode. The down stab. keeps the model stable on climb.
Everything is adjustable via small screws to trim the model for best performance.

I should add this new model of mine is very old style as such......very '70s/'80s, as that's how we made them back then. The latest and greatest are far more complicated and far beyond my capabilities.
