I am going to make a discussion about flight controllers here.

Topics include sources to purchase from, Board design, brand names, controller software, etc.....

I am going to start by going over the 3 F/C's I have in my 3 quads.

First the Vortex Fusion Gen2 FlightController, with OSD, and BlackBox Recorder using Clean Flight

Next the Blade Theory and it's Spektrum SPMFC3207 Flight Controller using Beta Flight.

Finally the Lumenier Quad with it's LUX V2 Flight Controller also using Beta Flight

Stay tuned.

-Tom

Update - 8-3-17 - Cannot find any source for the manual for the Vortex Fusion F3 Gen 2 F/C.

Disappointed and IMHO this is the type of thing holding this hobby back.

As even when you find the F/C manual it does not have some of the info you need? I posted here and on FPVLAB so let's see if anyone answers from Immersion on either forum. more info ASAP on the Fusion F3

Next on to the Spektrum SPMFC3207 Flight Controller using Beta Flight. So I can download the manual from here, Horizon Hobby is great!

https://www.horizonhobby.com/pdf/SPM...nual-MULTI.pdf

However IMHO this manual is far from complete. Does not go over the start up beeps, or lights, or much of anything IMHO for that matter. Am I wrong here? I got no info on what if I want to hook up LED's? Or Info on the boot loader button.......but I guess that falls on General F/C info and Betflight/cleanflight type stuff?

Remember, I am a Newbie so I am writing this from a newbie's perspective....Continue Reading

I have had my share of glow engines complete with the instruction manuals. I have never seen one quite like this before! I purchased this engine here on RCG for less than it was listed at; good thing since the engine was not complete. Now I have made a few videos of this engine and my Look Inside, not made public just yet. The only paperwork that came with this was a tips leaflet titled "Vmax Please Read This First!" This is the most honest, to the point, no holds barred printing I have ever seen. I LOVE this! Now I may have different feelings about the engine, but the writers of the instructions are spot on! I have attached the document for others to read.

Pay special attention to page 2, paragraph d, but the entire thing is worth reading. I cannot tell you how many times I have encountered this EXACT scenario at fields that I have flown at.

Now this particular engine is distributed from a place called Richmond RC, http://www.richmondrc.com/ The website looks a bit ancient and I really cannot tell by visiting it if it is still operational. I did send them an email to test the validity of the site and store, but I have not received a response yet.

As I mentioned above. I did completely disassemble this engine to inspect and clean it. The folks have a much higher opinion of the engine than my inspection revealed. I have run the thing one time thus far and for a 52 sized 2 stroke, it is not that impressive really. The quality of the materials looks....well like typical Chinese made glow engines, marginal. The crankshaft is so odd that it looks to be designed to shear in a crash, or even a prop strike. I have never heard of nor seen one of these engines before so I am evaluating it based solely on this used example that I have .

All of the excitement for less of the dollars

A quick test of direct driving the motors was another failure. Recycled the G buggy H bridge yet again. Without any position feedback, pulsing wasn't reliable at all. It also shook quite a bit, because the servo wasn't gradually slowing down. Putting brushless motors in the servos would be the next step up. It would be quite involved. In the last 15 years, a few smaller equatorial mounts have emerged at lower prices. The rise of DSLRs making timelapse movies has enabled smaller mounts.


This one is just the right ascension gearmotor. It has to be polar aligned on a tripod.

That ended another bid to make a 2 hour timelapse. A timelapse could still be made like all the others, by hand tracking & drifting. Despite NASA's best efforts, no other timelapses are as solid as what the lion kingdom got from hand tracking in 2012 & 2007. The 2012 solar eclipse was done without a filter, just cropping a 100mm, F32 & 1/8000 without live view frying the sensor.

Annular Eclipse Timelapses (1 min 22 sec)


Despite only 172 views at a time when unknown channels got a lot more hits, it was the only footage which could have made a decent timelapse.

Can anyone help me find a way to wire up a charging system for my battery .

As a guy who did a stint as a tech writer, then examiner of contracted tech writers, I have a few stories to tell..

We often put in fake stuff to see if anyone really read the darn things. Best one I saw was a trouble shooting flow chart. It went on for about six pages. Was ready to give up but had a hint that there was something hidden that I missed since I never saw one go that long.

Yep on page seven, "If hitting the reset button six times, while drinking Jim Beam and standing on one foot does not work, Take the elevator to the roof and throw the damn thing over the edge because it is busted and warantee expired six years ago because this sucker never fails... Train your operators right and you will never see this error."

They were pissed i found it. Wanted to see it in print. I guess they had a pool going if it would be found.

Another called for a special tool called "triopenen" to gain access to a welded shut panel.

I have a trip to Russia planned. I have enough money to get there and back. Not sure how long I'll be there but if I find a nice place to live and fly from the yard I will try to stay permanently. For now I'm going to go there and see how things are.
I can go any time, maybe after the weather gets better and I'll also get photos.

I was flying today and i crashed and my battery got hit pretty hard and got smushed pretty bad. All the cells are reading normal levels and the battery is not puffed. Is it safe to fly on a lipo battery that is dented or crushed?

Departing Horizon Hobby was a shock for me. I had planned to stay there until I retired! Unfortunately, we were kind-of going in different directions, so just over two years ago now (has it really been that long?) we parted ways. For the first year, I was focused on finding another job. This just didn't work out for me. However, at the beginning of the second year, I felt moved to start my own business(es) and do my own thing. One of them I have not yet begun working on, but the other one is making progress, the one you're probably interested in if you're reading this blog.

As I mentioned in a post or two, I'm working on starting my own kit business. It's gone a lot slower to this point than I expected, but things are starting to accelerate now. What took so long was learning a new CAD system. (Well, that, and a 6-8 week consulting effort that took up some time in the October-November 2016 time frame). The last CAD program I used was CATIA, and that was v4.1.9, long before the days of v5 and about the time that Dassault acquired SolidWorks. For budget reasons I decided on Autodesk Fusion360. As I assume would be the case with any package, modern CAD systems just don't work the same way they did 18 years ago. Much more powerful, but you have to go about the design process differently, and coming to terms with this new way of thinking is what has taken the most time.

I've had to start this design FOUR TIMES from scratch!

Attempt #1: Model was sized too...Continue Reading

Hello,

New to this group and sure is a lot of information! I have been flying a MD3.0 from Extreme Fliers and enjoy it a lot, but I bought a Goolrc T36 about 1 month ago and now have the bug! I had a blast with this small quad copter but the motor lasted 3 days so I sent it back Then after looking around I settled for a Eachine e011 two weeks later. Even faster than the Goolrc T36 but I must have bad luck because the motors broke on that also, I'm not that bad of a flyer either so I sent that back too but Eachine sent a new replacement to me for free, Amazon purchase. Was a little disappointed but saw an add on craigslist and bought 2 used Eachine e010c's (red & green), bought a Quanum V2 Pro from the seller earlier, and had to settle to fly the LOS because I suck at FPV right now Well I understand motors go out so I thought after reading a lot I bought some motors off Amazon, faster shipping, so I settled on the "Crazepony 4pcs 6x15mm Motor (Speed: Insane) 19000KV" for $13.00. thinking they would fit the e011 but they don't because the motors for the e011 are larger my mistake after reading maybe to much reading. After the green e010c started to perform bad I replaced the motors on it but used the board from the e011 on the e010(c) frame with the new crazepony motors using 150 mah 45c batteries and it flies very well. I got about 4-5 minutes flight time but I get better range when I go straight up and it kicks real well after multiple hovers outdoors. Very pleased with this setup. Happy flying!

As of Jul 31, 2017, 2:26 PM PDT, Betaflight 3.2 is in the Release Candidate stage and with this release, F7 flight controllers have arrived.

The fully formatted version of this article (with pictures) is here: https://nathan.vertile.com/blog/2017...ght-omnibusf7/



That is a photo of an early OmnibusF7 prototype with 2, user selectable, gyros: MPU6000 and ICM-20608-G

While an F7 MCU is not entirely necessary, not yet anyway, having a very fast and very capable MCU is future proof. I expect some of the most exciting new performance features in Betaflight will target the F7 MCU. This article is an overview of the current F7 landscape.

As of this writing, there are 8 F7 targets in the Betaflight source code:

Code:
ALIENFLIGHTNGF7
ANYFCF7
CLRACINGF7
FURYF7
MATEKF722
NUCLEOF7
NUCLEOF722
OMNIBUSF7
The only 2 that I've got my hands on so far are the OmnibusF7 and AnyFCF7. I hope to add more to this article over time.

Why choose an F7 flight controller?

Compared to the F4 flight controllers, which run at 180 MHz, the F7 runs at 216MHz.

More important than clock speed, the F7's "superscalar pipeline and DSP capabilities" put it ahead of the F4. Ok, sounds cool, but what are "superscalar pipeline" and "DSP capabilities."

DSP stands for digital signal processing, which includes special commands for Multiple ACcumulate (MAC) and Single Instruction Multiple Data (SIMD) instructions. These special instructions let the...Continue Reading

Just got this plane yesterday. Looks absolutely great. Will be busy building the plane this week. Details about the build later.
This plane calls for a RimFire 50-55, I purchased a Leopard Motor 50-55 650kv for $50. However the motor box is set up for the RImFire. I popped out the wing nuts. Filled the hole with a wood dowel and wood putty and repositioned the wing nuts to fit the Leopard Motor.
Finally got this together, it was easy enough. Just concerned about the CG. It’s 4 inches from leading edge. When I put in the battery it’s slightly back from that. I will try to make adjustments where I can. Don’t want to add weights
This is a BIG plane. I will most likely have one of the more experienced pilots take her up first.
It has been a long time since I got to this plane but finally put it together. It’s a big plane and flies GREAT
