Well I finally fixed my elevator that had broken off and went for another flight with my brushed RTF. I flew in the middle of a large football/soccer field, but sadly my piloting skills made my SS seem drawn to every large metal stadium light pole. Out of 2 flights that lasted longer than 10 seconds, both ended in a collision near the top of the light pole and a 30 ft drop to the ground. Pretty resilient foam, but one of the wings got a crack from the middle of the wing diagonal back towards to the corner of the aileron. I CA'd and taped that crack together, but the leading edge of the wing has a 5" crush dent mark. Is there any way to get the dent out of the leading edge?

Soak it in hot water.

Oh man, I don't think I can on my turnigy escs. I have a couple of cheap ones coming in the mail from grayson with the microjets I bought, I'll see if they have configurable boot up tones.

I've had some success using urethane glue as a sort of foam bondo. I had a minor dent in my nose that I fixed with gorilla glue, sandpaper and packing tape. Looks like new since I always cover the nose with tape anyway.

I've read that other people have used lightweight spackle or something which I'm going to try on my depron scratch builds on score/fold seams.

IMO, both of the above suggestions are excellent. I would just add that you make sure the water is not over 200 degrees because it will "mangle" the surface of the foam (think basketball/alligator looking) But, if you do get that, use the convex side of a spoon to "iron" out the flaws.
I think what Dkumagai is referring to is "Microballons" filler. I have used it several times and it is like magic to fix those really deep dents without adding hardly any weight. Try it, you will love it. Oh, here is a link:

You can probably find it somewhere else cheaper. I bought a gallon of it a year ago. I have used very little of it. So, I do not recommend buying that much. A little bit goes a long way.

Amishlou.

If the dent was smaller the foam has a memory and a little heat from a hair dryer or heat gun will help it expand back to normal. You just have to watch that you don't apply a lot of high heat or the surface will start to "popcorn".

The size of that dent requires the steps that NorCalMatCat, Dkumagai and AJ gave you. Really warm water, filler then shape it and tape it.

I actually had not heard of the Microballons that AJ mentions and will get myself some. I can always use something to patch and shape my foamy.

Boy that's a first.
Actually it's not. Saw a guy do it with a EZ*. Kinda neat the way the plane looked like it was flapping like a bird in flight. Brought a tear to my eye.....after I crashed.

My new camera mount for my Kodak Playfull camera. We'll see how it goes this weekend. I used the mount from plans found on ilovefvp.com and added styrofoam with a nylon screw on the bottom of the mount to attach the camera

Both of them. there are four of them,[some others i can't remember}
1.small 3m hooks, 3mm cf tube {four pieces} and elastic.+balsa inserts.
2.magnet method.
3.velcro.
4. gluing, or some sort of silicone that is easily to remove.

Should'nt there be more options on page 1.
Oops i forgot one. The nylon/light metal cubbord latches, iguess that's 5 isn't it.

Thanks for the help everyone. Next time I will aim for the poles like 2500GENE replied and then I'll miss them.

24.05Ap
11.29Vm
276.0Wp
2212-6 with SF7x4:
35.32Ap
10.11Vm
356.3Wp
So, you might want to try a bit bigger prop on both motors just to experience more pi-zazz. The only caution is the second one is ~5A over the maximum rating for the motor. So, I suggest you do not use WOT for very long and a LiPo of at least 2200-30C to keep the Lipo safe. Make sure and take some videos to share. Oh, if you want to go insanely fast with your Sky Surfer, get a MicroDan 2505-2835 motor (pricey-but worth every penny) with a 6x4 and it will really get up and go vertical until you cannot see it anymore. Here are the stats for that in my SkyS:
42.87Ap
10.41Vm
449.7Wp
Prof100 suggested it and I have to say it was a rush to fly with in a SkyS. But, in the end, it was just too much horsepower for my needs and desires. I have a video around somewhere. Hmmmm....
AJ
I actually propped down from a 7x4 to a 7x3 with the RC timer CF2812-1535. IIRC I was pulling about 15A with the 7x4 and haven't measured the 7x3 but I would guess somewhere around 12-13A. Even with the 7x3 it'll still climb nicely at a 45 degree angle. The 7x4 would just about go vertical on a fresh battery. It was more than I needed or wanted. I had hoped to use a 1300-1800 mAh battery to keep the weight down but even with a 2200 it just balances without additional weight. I've thought about stretching the nose a couple inches so I could use a lighter battery.

My Bix must have a warp somewhere. In a power off vertical dive it requires more and more left aileron as the speed builds up so something isn't quite right. It's fine for what I use it for (AP) and it glides better than I thought it would. I've got other planes for sport and aerobatic flying.

A SF7x4 on a 2212-6!!! Remind me to never buy a used motor from you!

I see the options on wing holding in Post #3 - Steps 5 & 6. Are there more attachment methods listed that I don't see? the 3M hooks are sort of like the method in #5. But, I will list the magnet method in the future. I did not post the gluing method because that method is in the assembly instructions that come with the kit. Besides, gluing the wings in is so obvious that I decided it was not needed. Thanks for keeping me up on page #1. I do try to keep the accuracy and content up to date as required.
AJ
P.S. I will have to do the research to find out who came up with the magnet method first. Oh, spar reinforcement is covered in post #3, Steps 22, 23, 24, and 25.

Planes, light poles... that reminds me of a YouTube video.
