Comparison of Spektrum Airware Transmitters to the FrSky Taranis Transmitter

One of the most difficult, yet most important, decisions an RC hobbyist must make is which transmitter to choose. One of the most common decisions users face is choosing between a Spektrum transmitter and the FrSky Taranis. No one can make that decision for a user and the best way to make the decision it to try both systems. My goal with this document is to try and provide facts about the differences between the two systems. A fair comparison is extremely difficult because the programming approaches the two systems take are very, very different. This is, perhaps, the reason opinions often seem so polarized. I like to think I am not biased since I very much like both systems and I refer both systems often. Which I recommend to someone varies based on my knowledge of the person’s technical skills, patience, desire for customization, personality, etc.

This is not a review; rather it is a comparison with some of my personal comments and opinions included. I welcome comments/suggestions from the community and I have no doubt there will be corrections and additions to this document. Since Spektrum and OpenTX are so different I had to devise a method for comparison. I am certain my method is imperfect and will need tweaking, but it is a start. My method started with a Spektrum transmitter model feature matrix I authored for myself and the Spektrum community. Since every day I see users...Continue Reading

This blog is in response to multiple requests for a parts list following my Reddit post here and details my attempt at building the cheapest mini quad with off the shelf components. I will also discuss the parts you could change if your budget allowed. Please note that if you are new to the hobby and don't yet have the tools and other bits this cost could be considerably higher.



Frame - £9.49
The frame is the popular ZMR250 in G10 from ebay and was the absolute cheapest I could find. Mine arrived with a sort of greasy residue around where the holes were machined which I had to wipe off before I built it. The ZMR is probably the most popular mini quad frame and certainly has the largest community despite purportedly weak arms. If your budget allows I would recommend the carbon fibre version since they are lighter and stronger and a power distribution board as you may find it difficult fitting all the wiring between the bottom plates.

Flight Controller - £15.99
My flight controller is the Hobbyking Naze32 and I see no reason to use anything else. This works well even with stock PIDs and can be flashed with Cleanflight too (though I haven't).

Motors - £23.08
The motors used are the ZMR 1804 2400KV and again were the cheapest available. You will need longer screws (I used 6mm nylon M2s) and instead of getting two CCW I would recommend getting all CW and using nylocks instead of the prop nuts.

These motors are good value but don't offer that much power; at least with 5030s...Continue Reading

Well I when a year still running a two xt computer's. I could not be more lost on this thing. Looks to be a salesman of nothing a price for everthing and you own nothing even after you pay for it and keep paying for it on your 100.00 a month free internet. The last time I went to a free park did not cost me anything. Trying all the free games that are not free. My son's in my room helping me every few min. May need to get another flight simulator for this one. And run a wireless radio for it maybe my Dx5 for it, has very few usb ports on it. well I did get a picture up with this post.

Stagility mode for SAFE equipped planes.... Its not just for quads anymore!
Work of Genius for Dummies
Contribution by RCG member dacaur .
too good not to archive
= = = = =

So having recently gotten a blade 200QX, I have been doing a lot of reading on quads, and stagility mode is something that's come up..... Stagility is a mix of stability, and agility.... Basically it allows you to have full control when you move the right stick (assuming mode 2) but takes you back to beginner/self level mode when you let go of the stick!

So I thought, well, my sport cub S, along with any other plane with SAFE, delta ray, apprentice, super cub S, etc, has self leveling mode, so why cant we use stagility on them?

Well, turns out, we CAN!

I like to fly around in beginner mode, for carefree flying, but like to do stunts too, so I have to switch it to advanced for my stunts, then back to beginner...

Well, not anymore. Now I can fly around, using the rudder to turn, and be in beginner mode, but as soon as I want to to a loop, or lose altitude fast, all I have to do is use the right stick, and its in advanced mode until I let go of the stick, at which point it goes back to self level, all automatically!

Stagility V2 is here, new and improved, no elevator flutter like V1 had....

What this does is use panic mode to give self leveling, then moving the right stick turns off panic mode, and you have full advanced mode until you release the stick, at which point it goes back

After looking at the Helm area I decided it just wasn't cutting it.
Even though I'm not really going for a Fully Scale build I thought I could do better.
Another thing that got me thinking about redoing the helm was the arrival of the Crew... ;-)

In any event I decided to add a Pedistle for the Wheel to be mounted on, and rebuilt the Throttle Housing.
I also built up the Captain's Chair.
Got the Dashboard and wooden Inside Hatch sanded and Sealed with Minwax Polyutrthane.

I'm liking it much better over all.
Still need to finish up the Chair, and build a mounting Pedistle...
And I'm considering adding a couple of Bunks on the back wall.
We'll have to see about that.

Plan to get back to completing the Lower Hull today.
Need to add a couple coats of thinned resin and some sand it down again.
Get the Running Gear mounted then attach the Deck.

Here are a photo or two.

From Flying Models, December 1958

Quote:
A rumor is circulating the one of the Eastern States is contemplating a law which would require model flyers to obtain State licenses. This has been prompted, according to the rumor, by increased accidents resulting from the operation of model airplanes.

Windy today no flying. got some good flying last Sunday. the twin F-22 is great flyer. the advantge of a twin is if you loose a motor the other one will fly you to the crash site.

Like many people I haven't found a prop I haven't broken, but what I've discovered along the way has been interesting. I wanted to take a moment to share, because I was unable to find any good info on props quality and durability when I started flying. For reference I've flown all these props on my ZMR250
  • Gemfan 5030 - Nylon prop that is quite durable and quite forgiving. These are tame little critters that generate thrust, and are the most commonly found props for the 250 sized quads. Our LHS carries them for a price.
  • Gemfan 5040 - The big brother of the 5030 and still quite durable and forgiving. I personally like the additional thrust they generate.
  • Gemfan 5045 - These are currently my second favorite prop, they are a much stiffer plastic than the 5030 and 5040, which makes them run quite a bit differently. Lots of thrust out of these, but they are VERY brittle and do not forgive being bent at all.
  • Gemfan 6030 - The 6" nylon version of the 5030, these have a bit more thrust but are flimsy and I think deflect on my motors. That said I think I know what deflect means, so I could be wrong .
  • Gemfan HQ6045 - These were a lot of fun, LOTS of thrust, very stiff prop, that shatters any time it hits anything. The problem is I hit lots of things.
  • HQ5045BN - These are my current favorite prop, however due to cost per prop I'm running the cheaper Gemfan 5045's. As I improve my piloting skills I'll be looking at 5045's from HQ that aren't bull nose, or purchasing a boatload of these!

Going to Waxhaw NC (just South of Charlotte) for Memorial Day and was wondering if there are any flying fields/clubs in that area. Thanks.

Anybody put a DLE 20 in a Hangar 9 Spitfire 60? Wondering how it fits and what modifications are needed, especially re; motor angle if it won't go in the motor mounts that come with the plane.

Thanks

My awesome wife gave me a Hero 4 Silver for Christmas so naturally I wanted to shoot better aerial video compared to some older footage I captured with various point and shoot cameras.

To get things going in a short amount of time and effort, I simply affixed the flat adhesive mount towards the front of the tri, just in front of the KK2. This worked out well but shooting in wide angle mode I could still see a bit of the two front props. I got in many great flights in this configuration. Until one cold snowy day. I failed to adequately tighten the screws for the front booms and one of them folded back mid flight. The tri was very high up in the air when I saw it go into a barely controllable spin. I was somehow able to guide back closer to me and just before impact it flew into a low tree. Two props broke and the GoPro detached. The tri was safely cradles in some branches and i was able to easily extricate it with a gold umbrella I had in my car. The GoPro was totally undamaged because it landed in snow.

Naturally I wanted to find a better way to attach the GoPro. I was confident that it wouldn't have detached during a regular incident free flight but I wanted something better. As I contemplated the different mounts I was looking at the tripod mount (not the quick release one) and thought that if I drive a screw down through both the top and bottom plates and attached the tripod mount from the bottom I'll have something a bit more stable and much more secure while improving it's ability to shoot downward angles. I can say that after one successful test flight I am very happy with the results. Video is very crisp and clean and the setup seems to fly better with the camera hanging below versus mounted up high. I'll post a picture of the current setup after I receive and mount the Fortis landing gear.

Update: Picture of GoPro mount below

Happy flying!

We have been waiting for a rainy day to shoot video of the Splash Drone flying in the rain. That much needed rain came today at about 10:45 pm eastern time. Wish we could have shot this video during the day, but I didn't want to miss the opportunity just because it was night time. we quickly grabbed one of the prototypes and brought it out into the rain. Just shot this and edited real quick to show it in the rain.

Also, check out the Nav lights and the camera gimbal in action. Do you like the Nav lights?

Here is my review of the JJRC H6C micro quadcopter.

It is amazing how much things have been provided inside 40$ shipped box.

Unfortunately there are couple of weak points, like FoV and too much facing down camera.

Possibly with a lens mod it can become a perfect copter ... but .. they could have invest 9$ more, and put a wider lens ... still for less then 50$ a decent 720p micro quadcopter would be still good priced ... but in china they don't like to spend on decent lens (at least for now)

Sticky: New SR-7?
Posted by bob57hdt | Mar 24, 2015 @ 01:14 AM | 1,904 Views
Back in early 1980's, after the SR-7 had established itself as the go fast slope soarer, I would occasionally get letters or phone calls (remember, we did not have the internet or emails) asking what was next. Puzzle I would ask, what do you mean next?
They would explain to me that they have a SR-7 and they are looking for something faster. Faster? Have you run out of airplane? After some discussion I found out that when they first showed up at their flying site with their brand new SR-7 they were the king of the hill. Eventually other flyers got SR-7's and soon our hero no longer had the fastest ship in the air. What he was looking for was something that would again put him out in front.

I do not blame him, is some ways I created the SR-7 to do just that.....allow me to show that I could design something that would dominate the slope.

As I have stated before, the SR-7 was a no compromise slope plane that was designed to go fast and roll rapidly. It was not good at a lot of things but those that is was designed for, it did well. We often look for easy solutions to perceived problems. Being the best, fastest, smartest or best at anything else requires effort. Buying the latest may make you the best for a while, but as soon as someone else buys one.....there goes your advantage, now it comes down to effort to stay the best.

As my journey with Katie through the years in this great hobby, I got distracted and found that being a big fish in a small pond is...Continue Reading
