Just building up my Pinata. Doing it in 2 stages, first I'm gonna just get it flying right, then the FPV gear gets mounted. I'm pretty close to finishing it off, but I'm kind of stuck on the placement of the ESC.

I planned on burying it in the 1/2 inch slit that I augured out already, but then towards the end of the instructions it mentions ESC ventilation. Now I'm stuck....I have a 40A ESC, 3S battery, 35-30 motor, max calculated draw is 31A.

Should I back-pedal and try to mount the ESC on the top? Or is it fine with being surrounded by foam? Have people had good success with burying the ESC?

Thanks!

You will be fine. I never had an issue with any of my 7 CTH wings. All have the ESC in the foam

If your ESC is running cool it doesn't matter if you have ventillation. Run the motor up for awhile and check the temp of the ESC intermittently. If the ESC is getting warm or hot enlarge the slot on both sides of the ESC enough to allow some air flow around the middle of the ESC but keep th e ends of the slot tight enough to hold the ESC in place.

Look at minute 9:35 on this build video.

Here is another video from the same day with Jeff and Brent flying formation with Grim Reapers.

It is fun to fly with the planes below your feet and we are looking into the valley. We have also flown from the top of the mountain to the right called Timpanogos at about 11,600 feet elevation.

When we fly slope you will notice that the planes are flown different. You will hear a few bursts of power but most of the time the planes are flown at low throttle.

We get asked if the planes can slope soar up at this location. The answer is sometimes. On this particular day the wind was along the mountain not against it so there wasn't much lift. The best lift on this slope is in the afternoon when the sun heats the west facing slope and we start to get lift.

The advantage of power sloping like shown in the videos is we aren't dependent on good conditions in order to be able to fly. You may notice in the background the Bingham Copper Mine on the far mountain. It is one of the biggest open face mines in the world.

Some videos are too good to forget.

I just watched this video again and found myself laughing as I saw the flag pole over and over in the video and knew what was about to happen.

Send us your videos.

I'm just tickled pink that Lee has thrown a blunt section at the favored Assassin to make something more FPV-worthy while still compact. So - Thanks Lee! (should have done it last year but hey..)

Better late than never. We also have the extension on the Grim Reaper if you want a larger FPV plane.

If you haven't contacted the FAA about RC / FPV rules and legislation you only have a couple of days to do so.

Our sWARm is Sept 27th. Here is the announcement.

Friends and flyers

We want to invite you to the next radio control "sWARm" or as some know it the "UnCivil War" on September 27th 2014 at 10 AM till 3 PM. We are planning on the traditional mass launch, limbo and pylon racing plus some activities for the slow flyers. Please feel free to invite all the flyers you know and bring them with you. If you have prizes you would like to donate bring them with you. We will have 3 plane kits and several hats Crasthesthobby.com is donating to the event.

As you may know the sod farm where we have flown the sWARm for the last few years has been sold and the sod is no more so we have had to find a new place to fly that can handle a big group of flyers.

The sWARm on September 27th will be held at the Eagle Mountain football practice field in Ceder Valley. The practice field is 14 miles West of the American Fork Center Street Exit. It is a large open area where the RC pylon racers have flown for several seasons. There are porta potties there and we will be planning drinks and food like in the past.

Here is a link to the thread for the sWARm on RCGroups http://www.rcgroups.com/forums/showthread.php?t=2111872

Here is a map of it's location. On the Google map it doesn't show that it now has grass or its size but it will work and will be a great location for this activity. https://www.google.com/maps/dir/40.3274301,-112.0185754/40.3768322,-111.8145833/40.3294776,-112.0173238/@40.3403046,-111.9226302,14865m/data=!3m1!1e3!4m5!4m4!1m0!1m0!1m0!3e0


The sWARm has become a tradition and we hope that you can work our your schedule to come and have a great time. We are planning some night fly sWARms in the future.

If you want to receive event e-mail reminders please let us know and we will put you on the email list.


Thank you,


Lee
