No rigs with me, but wondering what's the deal with FPV here? I'm guessing "no"? Didn't see anyone flying, but there are plenty of awesome spots here.

Lots of great spots in Brklyn too.

Shot this at the end of last summer with an ADS400Q. It's one cut, no flipping or anything fancy, I was still amazed that I could even FPV at the time.

Obviously, I'd never experienced loss before. . . as evidenced by the over water flying. Today, I don't think I would fly the same route, Murphy's Law and all.

Ever since an unfortunate failsafe, around December, I've been interested in lower power vTX for some of my rigs.

I found this vTX at RangeVideo. It was advertised at 200mW, but I think it's probably closer to 100mW. I'll get a better idea once it's in the air.

At any rate, it might be a good setup for park flying with my mini.

The total weight of the vTX and Pololu voltage regulator is only 8g.

The antenna is a very basic monopole, so I will not have the range or penetration of a full on VAS setup. I'll report back my experiences on flying this setup.

I believe RMRC is now selling these vTXs, or something similar....Continue Reading

Shot this last summer in August with my ADS400Q. Had been FPVing for about a month at this point. I was completely in awe that FPV like this was even possible.

I was moving pretty good with the ADS. Unfortunately, I knew shine-ola about mounting my GoPro and was getting some shudder under hard acceleration and FFF. Still, I was able to pull a few shots that were decent.

Surfing on the "Third Coast" is trying(we only have cumbs) but on-shore winds make it perfect for Kiteboarding year round. Texas surfers are some of the strongest paddlers. No waves.

It is hot in this part of Texas but the beer is cold and food is spicy.

playing around, doing aileron rolls and vertical 360s .

My bearings were bad before this sesh. . . now they are screaming!

Mini300- Crashy Crashtonberg (2 min 38 sec)


Got some new 645 props today and test flew them. AMAZING. I got 9:30 on the Mini300, carrying a GoPro3(with Lumenier 2250mAh 3S battery!AUW 750g)

I was only grandma'ing it around the yard, but still. Also, I did take it down to 12% on the LiPo. . . normally stop at 20% but I wanted to see how close to 10 min I could get.

I was at 8:30 w/18% in the tank. That's not bad, considering the cargo I was carrying.

I'm hoping for 6 min of agro acro, with the same setup, once I get my new motors. Noticed bent prop adapters on all but 1 of the Cobras. lol Still, the frame flew, but you could tell it was irritated.

Getting new motors this week (thursday hopefully).

The break will be good as I've got some tweaking on the frame that needs to happen and I've been itching to fly my modified QX9(MT2216 1100KV) again.

Thought this might be helpful, since there is such a shortage of motors for minis these days.

The information was pulled off Lucien Miller's YouTube channel. Lucien's video covers the bearing replacement of a much larger Scorpion motor. Great how-to video. Definitely watch all the way through before attempting this.

I recommend that you purchase one of these.

$30 with the good ole HF 20% single item coupon. God I love that coupon! lol

I'm uploading a bunch of pics, all shot in progression.

. . . post any questions.

Finally fixed my Mobius, after having crashed into a giant mud puddle @ Drummond field (that big ag field I've been flying in all my QX videos. Basically, some of the only standing water in the field and I plop right down into it.

Dried everything off and tried to get the focus correct, but it looks like it still might be slightly out of focus.

Because of the foliage at this location, I was using a heavier setup. 800mW vTX + Mad Mushroom. Weights below.

In a lightweight build, the below numbers should be reduced by ~55g. Will be exploring this in upcoming videos.

AUW w/Glacier 1300mAh: 707g
AUW w/Glacier 1550mAH: 724g
AUW w/Glacier 1800mAh: 733g

More to come!

I've been receiving LiPos all week from stateside vendors. The one that has beat them all is RMRC's 2200mAh 3S. The shrink wrap color is godawful but it puts out a pile of juice, and does it very efficiently.

RMRC has always carried quality equipment, but I have to admit I am very surprised at the fantastic flight times I'm getting! Good stuff.

Runner up would be the Glacier 1800mAh 3S & Lumenier 2250mAh 3S.

Lumenier Weighs the ~same as RMRC(170g) but on my Mini300 rig, I get about 1 min less flight time. I can push it but I'm coming down with 15% in the tank at that point. Still, Lumenier products are top notch and their LiPos are especially durable.

The Glaciers are great. I love their size/shape. Kindof stocky and dense, so you can easily get to your CG with them. The 2200mAh was a little too heavy to get the CG correct, however, the 1800mAh works great and the quad is flies very aggressive with them, esp when I'm flying with a Mobius. The weight distribution is perfect.

Glaciers are also very durable and will take a LOT of abuse. They seem to be under-rated on their output (C rating). Although they're listed as 30C, they perform like a 45C-70C LiPo. Highly recommended.

I will typically fly the 2200 LiPos with a GoPro3 and the Glaciers with the Mobius. Flight times are roughly the same, but the RMRC shines with the GoPro.

As always, there are so many variables in this hobby, so YMMV. All in all, I'm very pleased with all the LiPos and you surely can't go wrong buying either (Glacier, RMRC, Lumenier).

Here's my setup. . .I need to put it on a diet. I could eliminate ~50g by moving to my Pico Wide flight cam and Vee 1.3 vTX. This would obviously help in flight times also.

Shout out to all my friends back in my home state. Have a Dos Equis for me, will ya!

Missing Texas today. Where I'm from, Cinco de Mayo is a pretty big deal. It's nice to see it spreading, even in VA. Dragged my better half out tonight to get some Fajitas. It's sorta like a law in Texas.

Doing a few hot laps before the rain chased me off. Good weather tomorrow. hoping to try out some 5.5X4.5 APC props. Fingers crossed they're good performers. More to come on that. . .

I'd read where someone had reduced range when using their LaserBGC modules when flying on UHF. I've shielded the interior of my Fatshark Dominators and added additional copper shielding to the tin shield included with the LaserBGC 1.3Ghz vRX module.

The results are really nice. I'd shot this a month or two back, flying my modified QX9.

QX-9 :LaserBGC 1250Mhz range test (9 min 22 sec)

As you can see in the video, I'm seated, and flying low altitude the entire flight. The field has a slight convex bowl shape to it, so, depending on how far away I am, I get some Fresnel Zone penalty, if dropping too low. Still, I think I'm around 6' at my farthest distance, which would be slightly below the relative horizon to my LOS.

Very pleased with the module.

Very strange behavior when flying. When slowing, or hard braking in turns, the quad wants to sit back, it pitches up. You've really got to ease up on the gas when braking or slowing down.

It's really bad with a GoPro3, not as bad with a Mobius. Still, I really can't say I'm looking forward to FPV'ing these guys.

Maybe it's b/c I'm using them on an H Quad? Seems like I've seen others fly them on X quads and the performance was really nice.

I will say, they are a lot more efficient than the APC 6x4 Speed 400s. I'm easily getting an additional 2 minutes in the air with them. I guess they might be the ticket for just cruising around. Agro flying, however, I'm no sure how to tune out the odd pitching behavior.

Any ideas?

Quad:
300mm Mini-H Quad
Cobra 2204 1960KV motors
BS 12A Simonk ESCs
AUW w/Mobius: ~750g

edit. . .
I think I'm going to send these back, which pains me as I really like HQ props (the 950 is amazing) and the build quality is soooo nice, even on these mini props.

However, in order to use these, I'll need to create a separate FC tune setting, which isn't convenient, obviously.

Never experienced this with any other prop. . . at least on larger quads. Maybe it's different on minis?

I've run APC 847, APC 947, Gemfan 845 (Nylon, CF, Nylon/CF), HQ 950. . . all on the same quad, with no change in the FC. The only tuning issue is a slight oscillation on some of the APC slow fly, which you can fly around, by using less extreme throttle.

I get no weird pitching with the above props. I've actually never had that issue before.

I'm hoping HQ comes out with a 650 mini Graupner e-prop style prop. It should have higher RPMs and be glass smooth, with thrust similar to a 5x4.5, I'm guessing? Fingers crossed.

Looking forward to loosing a few grams and gaining some space back on the mini.

I'd like a 5v version but FPV seems like a 12v world. I've seen a few places with the 5v Lawmates, but I like dealing with RMRC.

Also got some of their 3S 2200 LiPos for the Mini300. These will be the first I've tried from RMRC.

Also got some 6x3 and 5x3 props (HQ). My hope is to run 4S on the 6x3. More on this once I do some testing.
