Launch Trim?

Hi Mike,
The launch trim consists of two parts, the rudder and elevator. I've been putting them in separately, but I guess you could do them together if you're careful.
The rudder trim is one or...

QF II Flying!

Hi Mike,
You did a fine job on the build, looks great!
Good to hear you've got the model flying. It's really easy to toss and the trim is simple. Some flyers use a switch (like the flap switch) to...

Mountain Models Fan Club?

Hi Mike,
Sure, you're welcome to add anything related to the model, here. My threads tend to wander quite a bit anyway! Kinda' like my flying.

Hello Mike,
I think you'll enjoy the build, it's a bit time-consuming but not hard.

Flying The Q.F.II

Hi Matt, glad to hear you've started on the kit.
I finally got mine flying, and can say it's well worth the building time. Sorry no photos yet, I was flying alone and wasn't able to take any flight...

Hi Buzzbomber, sounds like you have your hands full!
I haven't flown the glider yet, after it finally stopped snowing, it's been windy and/or raining nearly every weekend. I'll get it going soon and...

Hi James + Frank,
Thanks for the interest, no flights yet, not even a test glide. The firsr real snowstorm of the year came this week, and even after it stopped the wind's been blowing pretty hard....

Hatch Hold-Down

I ran into a minor snag while aligning the hatch. The instructions suggest a tongue at the front and tape at the rear. This type hold-down has worked for me many times (sometimes using a small screw...

Done!

After looking at the balsa nose, it occured to me the model wasn't really finished. So, a quick sweep of the benchtop and out with the iron.
Now it's done!
RTF, but wouldn't you know it, snow last...

Rx, Launching Peg

The last couple of items on the build; Mounting the Rx + antenna, and the launching peg.
I used velcro to attach the Rx to the fuselage. First I routed the antenna, using small-diameter heat-shrink...

Controls Finished, Nearly RTF!

After setting the throws, I peeled the backing sheet from the servo tape and stuck' em down. The "Z" bends at the tail were next, then I put thread around the pushrod tubes at 3 locations. I checked...

Control System, Pt. 2

Here's a bit more on the control system. First I put the double-sided (Servo) tape on the servos, but didn't take peel the film off the other side, this is a "dry" run. So, in other words, the tape...

QF II Build

Hi Frank,
Thanks for the kind words. The build has been fun, no major frustrations. Some of the changes I've made have been more of a personal choice, not because there was anything lacking in the...

Controls, Pt. 1

This is the start of the control system. First I cleared the pushrod guide tube holes with a 5/64 bit held in a pin vise. This is the same O.D. as the tubes, which are supplied with the kit.
Next I...

Mounting the Wing

Again it's been a while since my last post, but finally got some time away from work and household duties.
Here's the wing mounting process. (2) 4:40 nylon bolts hold the wing in place. One of the...

Long Time Gone!

Hello Everyone,
Sorry it's been such a long stretch between posts, but I had to work two 60 hour-weeks (six 10-hour shifts!) this month. It was a new training period, hopefully it's over now....

Wing Tip Detail

Here's some details of the wingtips; On a DLG, this is an important step, since the launching peg is mounted into the tip.
(1) First, test-fit the tip between the upper and lower spars. Mine didn't...

Nice Job!

Hi JB,
Great build on the QFII! I hope mine comes out that well.
The lighter boom might help, but I'd be reluctant to cut holes in the tail surfaces at this point. The problem is, then you'll have...

Weight + Launch Height

Hi JB,
If you can get a lighter battery and re-cover the wing, the weight savings will surely be worth it.
But I forsee a problem; A lighter battery may not give you the correct C.G. And if you...

Fast Build!

HI JB,
Wow, you built your glider fast! I'm still struggling to get mine done. But I only have a few hours on the weekend to work on it.
From your description I can see where about 1-3/4 ounces...

Still Building!

Hi Matt,
Thanks for the kind words, I'm pretty picky about my building and my own worst critic! But overall it's coming along OK.
I know about the non-modeling time, seems every time I get some...

Wing Sheeting Finished

Here's some photos of the wing sheeting, top + bottom. I'm not too happy with my workmanship, some gaps where the L.E. angle meets the sheet. For some reason I had a hard time matching this up.

I haven't gotten to the tip peg or servos yet, but according to the instructions the pushrod guides are glued inside the fuselage. Starting from the rear, about 1-1/4" inch in front of the...

Prepping L.E. Sheeting

Another busy work week, but I managed to get in a few hours this morning. After slowly cutting to shape the L.E. sheeting (to accept the "Diamond" L.E.) a few bays at a time, I decided to try a...

Build From Scratch?

Hi JB,
I think building a new nose is the best solution, or making the best of a bad situation. I forgot you were building from plans instead of a kit, now you're a real "Scratch" builder!

Short Tail?

Left Wing Done, Sanding

Here's the left wing top sheeting, after it dried I sanded the entire wing with # 320 wet or dry, using only a sanding block. The CA leaked through the alignment holes in a few spots.
