I have been soooooo looking forward to reviewing this plane. This plane has been a little over 3 1/2 years in the making.This will be my Review of it posted here and on the earlier discussion topic thread posted here: https://www.rcgroups.com/forums/show...F7F-3-Tigercat.

Here are some earlier pre-release photos released by FMS. I am still waiting for the plane to arrive which should be here soon

The one I will be doing is the Silver "La Patrona" livery with a second set of wings modified to have a working folding outboard wing panels.

Tarot 680 Crash.

I need some input here with this problem. I have a video of my failure below .


Tarot 680 Crash T-Motor MN3508 Failure? (6 min 53 sec)

Tarot 680 Crash T-Motor MN3508 Failure?


I had an unfortunate crash yesterday. I was in auto-pilot Then shortly after switching to manual control I either lost a propeller Or the motor seized up. (The motor does not work now but could this be because it was on high RPM's with no resistance as it was falling.


Either way a hexacopter should be able to stay in the air on 5 motors right???


I'll also mention that I'm using T motor MN3508 380kv on 6s.

I'm spinning CF 1355 props And according to E calc The Max power is 340 watts.

The motors are rated at about 310 watts continious.

I will Say that the Power per motor is approximately 100 Watts at hover. I have rarely if ever punched the throttle to 100%

I have less than a year into this hobby and I love it but I built this hexacopter to be a reliable platform. I have only owned these motors for about a month and I've already had one fail???

I originally purchased Tarot 4108 motors (That actually have a higher wattage rating) but from what I understand their efficiency and quality control is not as good as the tiger motors.

Am I doing something wrong or did I just get unlucky? Since I have to do a partial rebuild to fix it I would prefer taking steps to prevent this from happening again.

Any input Would-be appreciated.

FrSky Taranis X9D Plus SE Special Edition Review Part 1 Courtesy of Banggood.com (9 min 35 sec)


Think about it this way, a new taranis X9D+ is around $190-$200, if you were to do all the mods that comes with the SE model, expect to fork over another $150-$170. So I highly recommend getting the SE over the standard plain Jane X9D.... save yourselves the future regret
Mods included are:
  • m9 hall effect sensor gimbals
  • salecom switches
  • hydro dipped case
  • detatchable antenna mod
  • custom thumbstick ends

Picked this up used from the classifieds here. Came with all the cables however the cable that monitors voltage had been cut from the in line adapter. Some searching led to a replacement for 17 bucks shipped. The new cable arrived yesterday so the unit is ready for install in the Huey, I'm really interested in monitoring the battery heat and voltage while it's in the air. Install and binding looks simple enough, you just have to face south, chant the secret words as you rub your tummy and pat your head doing the one legged stance from the karate kid. Easy peasy. I will get a second unit for the Hughes if this works as I hope.
8/8/2017. Ordered the RPM sensor for brushless motors. I'll now be able to monitor voltage, battery temperature and motor RPM from my Tx.

Moving along with the cockpit panels, I realized that the dash I was planning on building from scratch needed to be designed so that it could fitted and be removed while building the panels. So before I could proceed to complete the panels, I side tracked to build a template of the custom instrument panel.

Since my Super Cub plan is more a current day custom build, I wanted a few more current day avionics to be included on the dash, so I added a little more height to my design, ( over the cramped space provided for in the kit), to accommodate the dash layout planned. The extra 1/2" in height I added really makes a difference.

So far, I have sprayed two coats of Minwax Polycrylic satin clear coat to the dash build. I want the surface to be free of the grain effect from the wood. I will add as many more coats as it takes to make it perfectly smooth for painting.

As the dash now fits well, it needs a careful fit , sliding into place from above, at an angle, until it is seated. Rather than the leave the left and right edges straight and parallel with the frame, I added a small rap around key, to give the bottom edge a longer visual line. A little tricky to fit , but for me, worth the extra effort.
It's time to cut some holes and layout my dash design.

I picked up an Exceed Mad Torque 8 Rock Crawler a few months ago. I dig the idea of an autonomous crawler (I'd viewed a few on YouTube). With a spare APM 2.6 I had laying around this is what I came up with so far. I'm already looking at other boards though (Raspberry Pi, Arduino, Pixhawk,etc.)

To date all my gas planes have been 7X frames, single cylinder. I got the inspiration for going to a bigger plane after i flew a friend's EF Extra 91 with a DA70. Man those twin cylinder engines are so good!

So i started doing some research online, and talking with experts. I settled on an EF Yak 110. I just recently got an EF Yak 60 electric, and i simply adore it. Its one of the last 60 electrics I purchased, and it was clearly saving the best for last. I love the way a Yak flies nd I think the cowl adds some character. I am going to capture my build here, editing and appending the post as I go. I will include a final bill of materials when i am done.

All Days Indicated as Calendar Days (not the days i worked on the plane), with Day 0 being the day the boxes arrived!

Day Minus 2:

I received the Jeti receiver system a couple days prior to the plane arriving. I am going with a Central Box 200 with 3 receivers - this includes a receiver for remote power on / off. I really love this feature.

> Set up a model in my Jeti DS16, copying from my Slick 79. Zeroed out all the trims and sub trims. The Yak 110 requires 2 servos per aileron, 1 servo per stab half, and one for rudder. Changed main wing configuration to 2 flap 4 ailerons. In the servo assignment, added ailerons 3 and 4, and deleted the flap mapping. You don't have an option of simply selecting 4 ailerons without 2 flaps, hence the work around.

> Bound all 3 receivers and did...Continue Reading

I'm new to this but I thought I might share one of the most useful tools I use when working on RC planes...a machinists rule.

I used this tool a lot when I built my first plane this winter. It was a Sig 4 Star 20 EP. Our club, Midland RC Modelers Club, had a group build. We bought 23 of them and had a group fly this spring. No one was supposed to fly them until this event. This is my plane.

Hey guys, here is my review of the KingKong 90GT Micro Brushless copter. It is a pretty good model!

You can also find a complete part's list in my blog: ArxangelRC.blogspot.com

For daily updates and news you can also follow me on Facebook.

It is amazing how small these things are getting! Just a few months ago the E 90X was about the quickest thing I've flown in this size, and it was GOOD... but the KingKong 90GT is just stunning! It is fast, it is tough and it is made very nicely and the build is good! It is simply a very good option for those who want to go a class smaller in size.




SPECIFICATIONS
Motor centre to motor centre (diagonally): 90mm
Dimensions: 80mm x 80mm x 28mm
Flying weight: 67.2g (47.2 w/o battery)


ARRIVAL STATE

As usual from GearBest, my package arrived in a perfect condition, and with DHL it takes only 3-4 days! Very nice work yet again!


WHAT I LIKE

First and foremost it has to be the size. I am just shocked at how things are developing in the racing drone scene and the trend is simply to go smaller! To what end... we shall see, but for the time being some amazing stuff is coming out, and it is working out of the box, with very good results. And that didn't use to be the case just a while back!

Now, 90mm drones have become mainstream and I have to say they are built amazingly well, come pre-assembled and pre-programmed, so all you need to do is match video channels with your goggles, setup 2 switches on your radio for arming...Continue Reading

Anyone of you have tried this? The foam pad is made by Skyzone for Skyzone 3D goggles. But actually except the Skyzone goggles, this foam pad is aslo fitting the Fatshark goggles. No more light leaks and more comfortable.

LX B-25 idea

Posted by SFLCouch | May 12, 2017 @ 10:21 AM | 3,354 Views
Hey all (if anyone reads this)!

I just purchased the LX B-25 from Banana Hobby, and I have an idea to do something using a few cameras, that I don't think can be done correctly, but maybe someone already has. Haven't seen anything! My Dad and I took a flight in B-17 this past spring, and while building this B-25, I had an idea of putting those all-in-one FPV cameras in it. When we went on the flight, I was able to sit in the individual spots that the crew occupied and pretend to stand over the waist guns while in flight. Now my idea is to use an FPV all-in-one camera in each of the positions on the B-25. One for the pilot, nose gunner, waist gunners and tail gunner. Each camera will be inside the plane looking out the windows, waist, etc. In theory, I could have 5 guys with different goggles randomly picking which camera (position), they can look out of. And then change positions by changing channels. I might just be thinking way outside the box on this, but maybe someone else has tried it, or anyone with more FPV experience could help me think of a set up, if it can even work. I have gotten really involved with the Honor Flight group down here in Sfla and was thinking it be kind of cool if the WWII vets that come to our next gathering could throw on a pair of googles and could see out of the plane. Some of the guys actually flew the 25.

Just a crazy idea by someone with way to much time on my hands!!!! If anyone has any words of wisdom or words of criticism, please let me know!
Thanks for the help!

Yuneec has been championing the hexcopter the Typhoon H as well as the Breeze. Both drones have gotten great reviews. Both drones have created standards. The Typhoon H boasts a six motor configuration that allows it to land safely if one of the motors stop. The Breeze got a great response as a selfie drone with some reviewers giving it a thumbs up. Unfortunately, both have seen better days.

Today Yuneec finds itself, like many drone companies in a battle to stay in business. Some hardware and service providers have found that getting paid has not been so easy.

Eachine Racer 250 PRO


Buy it here: https://goo.gl/p9WSen

For this article, I have to go all the way back to the beginning. It all started for me with a YouTube video of some guys flying quads through a forest. Having flown RC for nearly 20 years, I knew I had to try this fpv quad racing thing.

Thus my love hate relationship was born with my first quad - the Eachine 250 Racer.

I struggled to advance quickly with that machine. When I would crash it, I would break it. It lacked power and tuning was frustrating and difficult. My 2nd quad showed just how far the original 250 Racer was from a racer.

Enter the all new 250 PRO.

First Impressions

Just simply comparing side by side, the new pro version has definitely been changed quite a bit. These changes include: new frame design, new motors, new ESC's, new arm material and design, less weight, tiltable camera, smaller tail light, completely different power board and a different flight controller.

Setup

The machine comes built and ready for a receiver. But, because you ave to add the receiver it means you must connect to cleanflight. As you will see in my video below, that was not easy. Thanks to FryeSG I was able to flash betaflight to the f3 flight controller by changing the baud rate. (See my video) Everything else was straight forward.

Flight

WOW! This machine is everything the original wasn't. It's quick! Forward flight is smooth. It has more than enough power. When you chop the power it's...Continue Reading
