HD Squirt v2 w/ Vista, Mini Ducts and 9 minutes of flight time!

I am very happy with the Squirt’s transformation. After switching to a DJI FPV Setup, I gained a bit more weight and my total flight time really suffered. I tried a few things to lose the extra weight but the only thing that helped the most was a larger battery. My current battery of choice is a Tattu 1300mah 4s HV. Most of the time I do not charge it HV because I feel when I charge a lipo to HV it does not last as long. For the most part I was happy because I am getting 5 minutes of flight time again.

Then I starting to learn more about Bidirectional DSHOT and how people are getting more flight time. Setting up Bidirectional DSHOT was easy because I already had a BLHeli_32 ESC, and all I had to do is make sure I had the most current firmware on my ESC. If you are interested in all my settings, I posted a screen shot of everything in the image gallery below. Around the same time, I came across a posting on facebook and how Robert Moss has some good PIDs for Betaflight 4.1.5. I sent him a PM and he sent me the screen shots of his setup. After I got everything setup, I gained about 1 minute of flight time with Bidirectional DSHOT and it also flies better with the new Betaflight settings. Now, I am about 6:30 minutes (7:30min in HV).

Next up, mini prop ducts and props. I do not expect any flight time increase with shorter ducts, but I was hoping for better flight characteristics. With “real” prop ducts, it will give you a lot of downward thrust. So, it gets challenging to fly when you fly very close to ground because of the prop wash. It is less of a problem if you are flying fast but when you are flying slow you have all this air pushing the quad all over the place. To my surprise, the shorter ducts did not have any noticeable negative effects. The flight times was about the same as the regular size ducts. I think I gained some more flight time with the weight loss. The biggest improvement is how it handles, especially with freestyle flying. The point of the Squirt is usually slow cinematic flights but now you can throw in some freestyle moves every now and then. Most importantly I also seen an improvement when flying closes proximity of walls, ground and hallways. It is almost a no brainer to switch to these mini ducts.

Finally, the new props. I have collected 3 different props over the past 6 months and never tried them out because they are a little too big. I would need to trim the props before I can use them. For some odd reason, I hate trimming the props. So, I avoid testing them until now.

The newest props I purchased are the Gemfan D76 Ducted Durable 5-Blade 76mm. I did not notice a significant noise reduction, but I did get hotter motors and less flight time. Maybe this might be a better fit with a larger motor setup. With BH 1407 3600kv motors, it did not do too well.

Next up are the iFlight MegaBee V2 3045 Props. I only learned about these on Facebook and people were raving how good it is. I have to say, these props have the best flight time between all the props I have ever used. I was able get an 8:07 minutes of flight time with a NON HV charge. My only gripe about these props are the colors. The red did not match the theme I was going with the squirt.

The iFlight Nazgul Cine 3040 is my prop of choice but with the next best flight time of 7:50 minutes. The time difference is only 10 seconds so the way I flew, or the wind condition could have changed the result. There are 2 reasons why I went with the iFlight Nazgul Cine 3040 props and that is because of the color of the props and how smooth it felt. No matter how I flew the Squirt, 9 minutes of slow cinematic flying or 4 minutes of fast freestyling, the motors always stayed nice and cool with both iFlight props.

I have 4 videos to show you my two flight. Each flight includes the DJI DVR and GoPro 7 video:

Warning!! This is long and boring video, the point of this is maximum flight time.

Awesome build!

Q. Can you take the setup you used for 7:50 flights, remove the ducts and re-test?

Q. How much shorter or longer is the flight?

The ducts will improve prop aerodynamic efficiency, but weight will also increase power draw.

I do not plan to test the Squirt without the ducts because it has been done before. You will get more thrust and flight time with it on. So, it is best to have some kind of duct (not prop guard) for this quad. However, you can gain some freestyle characteristic buy reducing the height of the ducts. I am NOT making any claims on the increase or decrease of flight time with the shorter ducts because I did not do much testing on that. But it will fly and handles better with the shorter ducts.

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
