Re: Small ESCs outside the UK

To be honest the braking isn't a major issue, but having previously only used braked escs I really noticed a slight sloppiness in the control of the robot when I did briefly test a dasmikro, almost as if you were driving on a slippery surface. But as you said the much bigger issue is how fragile the...

Re: Small ESCs outside the UK

You don't want brake Brake is something used in rc cars, where if you go straight into reverse it applies a brake instead of reverse. Without brake is good. I'm afraid you're not quite right on the braking. Braking on a brushed esc refers to what it does when the stick is centred (no movement), bra...

Re: decent antweight brushless

I do like the LeTodar, but unfortunately they've been discontinued.
I've not used one myself, but the Dys BE1806 has always been a popular choice, banggood has them in stock.

Re: GeorgeR's robots

That's a pair of Pololu universal mounting hubs... http://www.hobbytronics.co.uk/motor-hub-3mm?keyword=Pololu%20hub I drilled out the 4 threaded holes in one of the hubs, and countersunk those holes. I then ran bolts through the drilled out hub, through the axe arm, and screwed them into the second ...

Re: GeorgeR's robots

Really need a video of this guy in operation :D You're in luck... https://youtu.be/2Q1-1wDGhec I've added a comment on this video that's got timestamps for RBMK's fights (and my others) https://youtu.be/c_qfIdc_MSQ Jump to 43:40 on this one for a decent fight against Bulletproof (yay titanium spark...

Re: GeorgeR's robots

The bigger/heavier blades will increase the turning and gyro forces which could make it difficult to control - but I'll dial back the acceleration/braking and maybe adjust the angle of the main blades so it should move much the same as before. I'm also going to add some kind of adjustment for the mo...

Re: GeorgeR's robots

Believe it or not, the current version on RBMK was never supposed to be a competitive robot, it was entirely built to see if my weird gyro walker idea would actually work. I was delighted with it performance at Ant Freeze even though it didn't win a fight, so I was more surprised than anyone when it...

Re: Dual motor Axe bot

Not sure of the exact weight, but without the case they are pretty much the same size as a no-pin lemon rx, or a dasmikro, so will be in the same kind of range as those.

Re: Dual motor Axe bot

I wouldn't worry too much about power, there's simply no way to make a damaging antweight axe, but don't let that stop you - axebots are great fun. As others have said, it can be done by simply wiring both motors to a single channel esc, and running off of the rudder channel for control. For Axiom I...

Re: GeorgeR's robots

I use "EMA plastic weld" and find it works very well, apply it to both parts, then clamp them together for a few hours.

Be aware that the chemicals it contains (methylene chloride) are really VERY nasty, always use in a well ventilated area and wear gloves to avoid any skin contact.

Re: Dys or redcon brushless motors.

The Redcon 2204 that was popular for a while has been discontinued. The dys be1806 can be found in a variety of places, banggood have some currently, and there are a load on ebay. The other option that is gaining popularity is the Quanum Be1806 - you can find them on hobbyking.

Re: Power connectors identification / naming

1) JST RCY connector; sometimes called a "bec" connector.
2) yep, those are JST-XH connectors.
3) 1s lipos come with a variety of different connectors, but the most common seem to be the Molex Picoblade (that's what the small nano-tech ones have).

Re: Brushless motors

Yeah, I definitely suspect the battery is the culprit in this case, those 180mah ones will struggle in a spinner, especially with a powerful motor like that 2204. I use the 260mah 35c ones in Vampire and Valkyrie, and a 300mah 45c in RBMK. Despite the higher power lipos Valkyrie is the only one I ca...

Re: Brushless motors

Short answer - yes and yes. It's a common issue, but with the right setup you can get a very quick spin-up. There are two issues in play here; the first is that brushless motors can draw a huge amount of current at low speeds, and the small batteries used in ants can struggle to provide this current...

Re: Botbitz 10 amp ESCs for weapon

I'd say the botbitz 10a is definitely on the large side. If you're looking for a single channel esc the fingertech tinyesc, or the Vex 29 are much better choices. I use the vex to drive my axebot weapon motors and it's worked great.
