The Mobthicc V3 | Complete Build & Setup 

This is a 100% factual statement. *results may vary

Lmao I got one on my is250 as well

Hey man! Glad you enjoy flying it! The issues you're having sounds like a different gyro in your fc. HM changed what gyro they were using in the diamonds. I'll see if there's something we can do about that. But I'm glad you got it figured out! Let'er rip!

QUICKSILVER is ELRS V2, had to use my other radio. Haven't figured out how to blackbox or tune yet, just getting used to it. It's different then the last time I used it, I don't think it worked with SPI when I used it last, I have memories soldering a receiver. So far doesn't fly as well as BF4.4 but I am willing to give it a chance.

And for info you are wright with 35mm props on fractal 65 but with 12/12mm camera like the foxeer razer pico👌🏼thanks too Heads

I haven't tried gnb27s in a while but I heard they are better now. They used to get loose and lose connection all the time. Drove me nuts.

Hey thanks for the comment! 1. While beta testing the Fractal75 I tried several cameras, the Ant lite being one of them. In my notes it was the largest camera, weighed the most, and had pretty good image quality. I didn't fly it on the build though, being the heaviest of the ones I had available, I opted for the Foxeer Pico Razer instead. Weight was much less, better shape, the lens didn't stick out so far, and the image quality is solid. The only kicker was the pigtail needs to be changed when you get it. Yves from Fractal may have actually tried the Ant on it. I'll have to ask. 2. I'm going to assume it is from the camera used or the modifications made. I never have a problem with the camera moving. This very well could be because of the shape of the Pico and where the plug sits. I was extremely skeptical with the camera mount when I first tried the f65, I think I even mentioned it in my review video back then. That had the Runcam nano 3 in it and holds very well. Surprised me. 3. I can make mine flip on hardwood or my garage floor pretty easily. First or second try usually. I don't want you to think I'm messing with you, I uploaded one of my most recent flights with the Mobthicc. This is my first pack of the day and I was getting tattooed lol. So there is a fair amount of crashing and flipping on hardwood. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1LiiJEtFXNE.html 4. I use 450mah packs in mine, and 3D print my own holders. Some variables there. My prints could be getting squished a bit more so the space for the battery is slightly tighter. The 450s I use are wrapped and stretch the tpu pretty good. Every now and then I would get a bad crash and the battery would slide out. I put a small ball of BlueTac on the bottom of the carbon. So when you slide the battery in, it kind of squishes the bluetac down and adds some traction for the lipo to grip. Could also do a bead of hot glue, carefully. I hope that new holder works better for you. I say use what works for you. If the older build works, just fly that! The reason I swapped frames between builds was for durability mainly. I can't break these fractal frames very easily. Also keeping the weight down helps make those crashes a little less catastrophic, which is why I avoided the heavier camera with nice picture. I got tired of breaking things haha. If I left anything unanswered, or something else comes up, don't hesitate to let me know!

Appreciate your response! 👍 Of course, flying what works makes perfect sense, but we're here to also try new things! 😉 I hope my lengthy message didn't come out as rant. I think there's a lot of positive things to be said about the fractal: - improved durability you mentioned - not having to replace the entire frame in case one duct cracks - easier maintenance due to how nicely accessible the fc is - camera positioning means you can get that bit closer to obstacles and ground - better prop wash handling at low voltages (placebo or I have tuned v2 poorly) I'm going to give the pico razer a shot. Thanks for the tips wrt battery mounting. If it comes to turtle mode, I agree it works (eventually) on hard surfaces. It's the grassy outdoors which I'm slightly concerned about - TBD. I wonder what your v4 will bring. ✌

Ah yes, grass is a killer. I keep mine fairly short, but even then sometimes it's a walk of shame 😕 No worries on the message, didn't find it rant-like at all!

Yes! I love the Fractal frame! It remains my favorite whoop frame to use. EU retailer: www.drone-fpv-racer.com/en/recherche?controller=search&s=fractal

Hey Jeb! Great to hear you are enjoying the build. Quicksilver has some pretty decent preset pids for larger quads as well. I recently used it on a TuneRC 2s 3" build video. The stock 3" tune on QS flew really well!

@@InfinityLoops ok fantastic! I missed that video, I'll check it out!

X12 will work! It will be a bit heavier, but not too much.

I have tried ductless and it flies great! Some people even prefer it this way.

This is my next build..also thinking about going ductless. I'm also wondering how much difference there is in flight characteristic. If not much I might just do the ducts also...🤔 haven't seen any yet without ducts.

I had troubles connecting with Brave browser, Chrome seemed to work best. I love the HGLRCs, but this newer version has been spinning posts on me. Out of 10 I ordered, 3 have loose motor posts already 😒

@@InfinityLoops THANK you. Finally got it working after 30+ more attempts. Idk why I had such a hard time flashing but once I got it, it connects every time. Maybe a bug, idk

No worries, glad you got it working. I can ask the developers about it. What browser were you having trouble with?

@@InfinityLoops Chrome - I posted about it in the Discord.

Perfect!

I'm having trouble finding the FC that he used in this video. Would you be willing to help me find a link to one or one thats close to equal?

@@mattmoyer1912 I’ve found them but they have terrible reviews. Everyone I’ve talked to say say far away from them.

I wouldn't recommend this FC anymore. The QC seems worse and the boards are fragile enough to begin with. I have a Happymodel 2g4 FC on this build now.

As long as you are running the fc inverted the template should work. You need to make sure gyro moves as expected and motors operate correctly in the configurator before flying.

Mimicking a 65mm with anything larger in a racing format is difficult. 65s handle close proximity maneuvering like it's nothing. 75s turn more boat-like when compared. In my opinion, I would stick with the 65 to practice, may build bad habits flying a larger prop on such tight tracks. I'm not much of a racer myself, but from what OG has told me, practicing outside with the whoops can be rough. I have fond memories of him complaining about it. For racing practice, personally, I use Velocidrone micros dlc. Builds your muscle memory for the track and helps memorize your lines for the real deal.

@@InfinityLoops Awesome sir thank you so much I have velocidrone and the micro class on it.

sorry..Quicksilver firmware...

Not really. Personal preference, I find QS easier to navigate and work with.

@@InfinityLoops Thanks for that. Just starting with whoops and wondered if QS was better suited for micros.

I have no idea! Lol sorry, I never change them. I leave all that stuff alone.

Quicksilver has been beautiful. It is such a light firmware it was so easy to navigate. Betaflight is overwhelming to some, to me it just seemed like too many features I just don't need on a whoop. QS will be my choice of firmware for whoops for the time being.

@@InfinityLoops Thank you! I'll have to check it out. Any thoughts on EmuFlight for the same purpose?

Tried it a while ago. Didn't like it much, but that was a while ago I'm sure things have changed a bit.

@@peicou I love Emuflight on my 4” Apex, but I don’t think it has BMI270 gyro support yet (and the newer X12 boards use it)

@@tmdhvn That seals it! Thanks Feej

Lot of outside factors can dirty up your signal. That FC in particular I have had very hit or miss results with, as far as the VTX is concerned. Some get break up within 100 feet. Some I can fly 400 feet crystal clear 🤷‍♂

@@InfinityLoops thanks for the response. Do you usually run vtxs at full or found better results using midpower. Seems everyone runs full power but wonder if your better off not pushing them. I hated whoops for a bit but trying to get back into them for the winter 😀

When I'm in my house I've found mid range power is pretty good. I only bump it up to full power if I'm outside. I've heard some wifi signal can also cause interference, so I'm sure that should be factored in as well

Are you referring to the Fractal75 frame? I'm unfamiliar with any other carbon plate for the mob7 v4.

Yes, most recent version does have elrs 3.0 support

Had fluttering on 48hz. Not sure if it was me or what. But didn't have it on 24 🧐. No clue. I just go where the wind blows.

@@InfinityLoops Yah i’m struggling with some weird esc things on the diamonds like stuttering so i’m wiping and starting over today and i’ll pay more attention to 24…

Hey there! You're using ELRS?

@@InfinityLoops Yep, (TX16S-ELRS EdgeTX, no problem binding with my big quads.) Two identical builds, all other features functioning correctly, neither indicates any type of TX/RX interaction. I've tried binding as per your vid as well as using the bind button. Battery connected, UART1 selected, etc. (Thanx for the fast response BTW)

Ok. Let's start with elrs version. Which is on your TX? Elrs 2.x or 3.x? Also, which version of QS are you flashing?

@@InfinityLoops QS version is 9.5, looks like ELRS version is 2.4.0 on TX

Bingo! QS 9.x supports ELRS 3.x. easy fix, just need to update TX firmware.

I have! They perform just fine. Likely a bit longer flight times too. I flew 19000kv on this build originally. Then the 25000kv was suggested to me.

@@InfinityLoops Great to hear! Does 25000kV give you much more thrust across throttle range or just slightly more punch at top end? I'm thinking of getting 22000kV and hope I get the best of both world. Oh and are you getting 3mins with these 25k?

25000kv I feel like I lose some low end throttle control. 22000kv might be a good spot for you, kind of depends on your style. Yes, 3-3:30 flight times on a 450mah.

@@InfinityLoops This is how I fly: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-igtaaq7T0yU.html Thanks for the info man, Mobthicc is going to be my next go to whoop!

Should be OK. They have targets for it.

Yes it'll work very well config.bosshobby.com/

@@InfinityLoops cheers mate.. been reflashing all sorts of settings trying to get it to fly as smooth as yours.. hoping its not just a “pilot” issue 😂

I also run the default rates, which helps with keeping things smooth.

I’m running QS on my stock Mob7 1S and it’s great. I had to bump up the digital idle a little but otherwise 👌🏽

😆

I was super skeptical but used the original prints for a month, only reason I had to print new ones is I swapped a few different cameras a bunch of times and ripped one of the "teeth" with my tweezers after poking it a couple dozen times. They work great and are stupid light. They work unexpectedly well to be honest. One of the best whoop mounts I have had the pleasure of using. I generally carve custom patterns in Happymodel canopies to make them interesting and light weight. But these have been great. I haven't had to touch any of the TPU for several months, with general daily abuse.

It is such a simple design, it really works perfectly well. I've never had issues with them!

joining the hype train to say: I never expected to use the tpu camera mount, but I prefer it over canopies now! Great footage and less ducts in the way. I stuff some foam behind the camera to get the angle right. Very reliable

I have a feeling like I know what happened, yes. If you were using the DiamondF4 fc, those escs have a tendency to self destruct on their own. I would try reaching out to Happymodel and letting them know you had one burn up, they may grant you a replacement. These FCs used to be so solid, then suddenly not anymore. ESCs burning up on brand new boards.

Thank you so much, this is what happened, failed esc out of the box. Got a replacement and I am loving this build, Thank you!@@InfinityLoops

Wow, not long after building with the new board my new one now has an issue. I noticed it after doing a turtle flip, same thing as before, one motor only twitches sometimes and it struggles to take off at times and I can see one of the FETS looks like it has a bubble, just like my other failed board. This is making me nervous to continue with quicksilver and bluejay but I really enjoy the way this thing flies when everything is working right. Is this really all just down to poor board quality? Should I even attempt another board or is there a better option now? I want the lightweight but these elrs versions dont seem to have the quality behind them. Is there any chance this was from using turtle mode at 100 % in QS? Thank you for replying. @@InfinityLoops

From my experience, both Betaflight and QS would fry ESCs in the Diamond board. The FC is notorious now with popping fets. I have a massive pile of dead Diamonds from extensive testing of this. It's a gamble with that FC. You might want to look into a 12a ESC FC to run on 1s. Give you a bigger ceiling for buffer.

@@InfinityLoops thank you so much for the response. There really aren’t enough micro 1s boards with built in vtx and elrs. Might have to roll the dice again and hope for a good one.

Stock Betaflight Rates. 667 on all axis
