@LetsFlyRC 10 месяцев назад

Thanks for the honest review, Joshua. :) Just incase anyone is looking at the TanQ - I want to be upfront - it will not accept 20x20 stack - only 30x30. The frame that Joshua has in this video is a new version, that has already been strengthened around the break point from the Rotor Riot - straight into the ground video. I literally called the manufacturer the next day and revised the design. Always improving. Please tag me, anyone who has broken the TanQ and I will continue to make it the most durable frame on the planet. :)

@LetsFlyRC 10 месяцев назад

I think Bot and I totally have similar needs and I think he did a great job with his frame. Congratulations, Botgrinder on making a super durable frame. Love it. :)

@10111115 10 месяцев назад

Hi, Mechanical engineer here, having more threads through a nut gives some redundancy if it backs out at all, but the entire load is carried by the first 3 threads, so as long as you have 3 threads through, it’s as strong as it will be

@gqp4800 10 месяцев назад

Older machinist here. Always depend on application. 12.3 button head. I ran machines long ago we used metric and standard Allen wrenches with six foot pipe to tighten the strongest black thick bolts, most expensive.get what you pay for.

@Hobz79 10 месяцев назад

Absolutely, and I'll just add to that that that's 3 full threads (tips of screws don't count) and into a steel nut. Into Al or plastic I go 1.5-2x the diameter of the bolt respectively as a rule of thumb, but in a lot of cases you might not even need all that clamping force. It also assumes you want the bolt to fail, it's a lot easier to replace a bolt than a threaded part.

@10111115 10 месяцев назад

@@Hobz79 You are both correct. I suppose I was saying that as more of a fun fact. It was certainly not design advice. I would always recommend at least having the screw all the way through the nut. Preloading plastic like that isn’t usually to the advantage and will more likely cause failure of the plastic fixture. Bolts are the most easy thing to replace

@Joeyzoom 10 месяцев назад

I’ve been flying the demibot all summer and have been LOVING it. I’m much more likely to try difficult tricks because of how unlikely I’ll break something. It’s definitely giving me a lot more confidence that I wasn’t getting from my old Nazgul5X. Despite being significantly heavier, I’ve tuned it to fly pretty damn well in comparison. Props to Ummagawd and Botgrinder for this frame 🙌

I have a tanq I built... with botgrinder v2 motors... it's a beast.

@albinodinofpv 10 месяцев назад

The Tanq is designed for the battery to be mounted in a toilet tank orientation. Hence the two holes for the battery leads/strap in the top plate, and the lack of indents on the side of the top plate for a strap.

My preference goes for frames that use a cage to protect the camera. Also 8mm arm feel cool. I am very satisfied with my armattan rooster rooster except for the fact I stripped one of its holes (titanium cage hole lost the battle with stainless screw).

@dhbfpv 10 месяцев назад

I broke a bot back mid plate and my first bottom plate had delaminated at the counter sunk screws. I like it but for the price I switched my 5"s over to RDQ Source one v 5's. when one brakes I will just grab another. Also my tpu mounted camera would end up looking more at one prop then the other after a crash. Had to e6000 it to prevent it from moving.

@CarbonGlassMan 10 месяцев назад

The Tanq does something that FPV Cycle does with their Fouride, although it's turned 90 degrees, that I think every frame should do. Slots in the top plate to weave the battery strap through the top plate to not only hold the strap in place, but it also keeps it from slipping around. I don't know why every frame doesn't do this.

@Alluvian567 10 месяцев назад

For weight you also have stack screws in the botgrinder frame when you weighed it, and not in the tanq. I would think those frame screws weigh more than the 3d printed bits, making the botgrinder frame more than 10 grams lightter.

All I do know imo bot did it wrong with the park. Went from donate and if he doesn’t get to 70 grand in a certain timeframe he will give it all back. Broke his promise on that.I knew it wasn’t going to go good from there.Then he said the park would be for everyone to go fly at. Now he buys a landlocked land that he will take 10 people he picks once a month for the summer only. Haha, so basically he bought land for himself that we get to go fly whenever it works for him. I see him say he’s doing with what money he had to work with. That’s exactly why you should have given everyone money back when you didn’t hit your goal like you said you would anyway. I don’t hold any hard feelings but I’ll go back to my never donate money to people because some people just can’t keep a promise on what they say.

I didn't like the whole hand select 10 people a month for a private trip thing at all either.

Armattan Marmotte/ Badger for the Win! It's 40-60grams lighter, titanium camera cage to protect the front end and keep those expensive fpv cams alive. And most important, a lifentime warranty to just keep replacing the bits yoh do break. ImpulseRC Apex is another great frame for bashing concrete, and has a 2 year warranty. Anything you hit on concrete will eventually break, so a bit of balance will make yohr quad fly better and you'll be less likely to crash sooooo hard...and a lifetime warranty when you do explode the thing 🤣
