I´m currently using a Naze32 on this build and it looks awesome flying. Here are few things I would like to get inputs from you based on your experience. 1 - What ESC protocol should I use here ? PWM, ONESHOOT125 or any other alternative ? 2 - Loop time, considering I´m a beginner, is there any specific recommendation for this (still flying in Angle Mode) and sometimes Horizon to try some flips/rolls (40% success rate on this so far ) Thanks • Posts: 2,286 Threads: 38 Likes Received: 1,527 in 995 posts Likes Given: 1,881 Joined: Apr 2016 Reputation: 72 Use Oneshot125. Leave loop time as whatever is set by default. You won't be able to go any faster, especially if you need to have the accelerometer enabled for self-levelling flight modes. For future builds, you should consider an F3 powered board to be the minimum. F1 powered boards can often have problems with the latest firmware and don't have the horsepower (or floating point module) that an F3 powered board has.

For smoothest flight use the fastes ESC protocol you can. Oneshot is good, multishot is better, Dshot is the best. (As someone just beginning I might recommend using the fastest option that doesn't require extra flashing or hardware modifications.) Oscar has a good Dshot article here with links to the other protocols in it as well. Edit: As Unseen has mentioned With an F1 board I would probably leave loop times alone for now. Here is an article about Loop Times. It comes down to CPU consumption. When you get the hang of things and can turn off Accelerometer (no level modes) to help CPU load. Hope this is some help Posts: 155 Threads: 29 Likes Received: 36 in 28 posts Likes Given: 68 Joined: Apr 2017 Reputation: 0 Thank you Unseen and Droneofprey, I'll use Oneshot125 for now. I really liked Naze32, it's simple and the quad goes smoothly I thought Naze32 was F3. but this one has only 2 UARTs and as per Oscar's article ( https://oscarliang.com/f1-f3-f4-flight-controller/), looks like it's a F1 in fact. What FC would you recommend for future builds considering someone who is not doing lot of crazy flights (yet) ?

Posts: 155 Threads: 29 Likes Received: 36 in 28 posts Likes Given: 68 Joined: Apr 2017 Reputation: 0 Well, let´s see: 1 - Only flying LOS for now but I plan to start trying FPV, so OSD built in is a plus that should be considered. 2 - UARTS ? To be honest, the most I want to add other than osd would be leds, at this point I have leds directly soldered onto the PDB. At this point I´m not sure what else I could have to use the UARTS. 3 - MicroSD is also a positive point, but I don´t see it as mandatory. If I´m happy with this naze32 F1 I have, I´m pretty sure a F3 would do the job for me • Posts: 1,773 Threads: 30 Likes Received: 1,199 in 755 posts Likes Given: 714 Joined: Oct 2016 Reputation: 45 I didn't think an onboard SD was necessary until I started recording BB logs with an onboard chip. I get a minute max recording at 30% and downloading is agonizingly slow. I've got a BeeRotor F4 coming for that very reason.

For a build where you don't even need an external PDB, the Betaflight F3 flight controller from FPVModel has everything you need on one board. It's also not easy to solder to if you don't have skill and good tools. The Omnibus F3 Pro AIO is a good alternative - you still have a current sensor, but you need an external PDB. You can get the Omnibus from Airbot. Both have the OSD built in and you can configure it directly from the Betaflight configurator.

If you mean how responsive the quad is to your stick inputs then it's rates that you want to tune... since you're flying self leveling modes I think these apply a little less but I'd say get started trying to learn acro in a simulator with rates down into the 360-600 range with a little expo as soon as you can. This way you don't have to keep crashing on your attempts to flip. I am working on a tutorial for increasing rates while learning to fly and hope to post it sometime before the weekend. carl.vegas Current Quads: Operational: Diatone GT2 200 In need of repair: Bumble Bee, tehStein, Slightly modified Vortex 250 Posts: 155 Threads: 29 Likes Received: 36 in 28 posts Likes Given: 68 Joined: Apr 2017 Reputation: 0 Unseen, Renov and Carl, thanks for your inputs here. I´ll see what alternatives I have to buy one of these FCs, I´m happy with the Naze, but maybe because I don´t have a different perspective to compare. The only other FC I could test was a Flip32 F4, but to be honest it was a disaster as the flight was very unstable including motor cut-off from time to time without any explanation, I almost crashed a couple of times then I´ve replaced the FC by the Naze I have now. Thanks ! • Posts: 155 Threads: 29 Likes Received: 36 in 28 posts Likes Given: 68 Joined: Apr 2017 Reputation: 0 (23-May-2017, 10:45 AM)Carl.Vegas Wrote: I'd like to come back to your question #2 as I think maybe you're looking for something other than "loop times".

Carl, for now I´m using HORIZON mode, and I´m pretty excited because it allows me to do flips and rolls. Acro I need some more control, I´ve been playing with ACRO on the simulator, but to be honest, I don´t lose control and I can do some stuff, but when I put the actual quad in Acro, is a completely different story Maybe the right way to do it would be just do, crash as much as necessary and at some point you are flying, but the scenario for me is a little different as anything I have to buy in brazil costs roughly the 3 times the price of Banggood or Aliexpress. Crashing is part of the learning curve I get that, but I have to do it slowly as I get more confident.

Sorry, but that really did make me chuckle. I could picture your quad cart-wheeling across the grass in slow motion!

Super thanks That's why unofficially I would suggest sticking with horizon in the air but put at least half of your sim time in acro... Rough estimate: about 30 hours of experience in simulator in acro mode is enough to be relatively safe. this Is depending on how much risk you take. I've been high risk most of the time but I have had success at playing it safe... TBH because the quad fights you to stay level after you start to get acro the leveling modes sound more dangerous to me. carl.vegas Current Quads: Operational: Diatone GT2 200 In need of repair: Bumble Bee, tehStein, Slightly modified Vortex 250 • |
