Good man. We're a bit of a rare breed unfortunately (or fortunately, as it means more Pepsi for us!)

All hail Pepsi Max!!!

Finally other Pepsi lovers! I get an unlimited supply at work

Do want.

Surprised there's so many Pepsi fans, I'm among my own people at last haha!



Oh and Nick, I'm keeping the RPM a little lower I think, I wanted to go silly speeds but I've been chatting to Harry Hills, who said it's probably best to keep it slower and keep the reliable hits, and have it running an NTM 50-60 instead. Not ruling out the crazy fast disc yet, but it might not make it into the first version at least...

I agreed with Harry; there is no point to increasing the rpm past a certain point. The NTM motors have a great reputation or check out the SK3 motor range, which comes from the same factory as top Euro brands like Hacker. With the NTM 50-60 380KV motor @ 8S, you will only be getting 11K rpm without load. Under load and with a bit of gearing down, you might not get even 5K at the disk.

The HeliDrive SK3 4962-530kv motor will give you 15K rpm without load and is the same size as the NTM 50-60. It also has more poles which will give it a bit more torque at start-up and reduce the spin-up time.

I'm with Nick here, that SK3 4962 looks perfect for what you want. It also fits perfectly into the model, giving an extra ~400g and 2cm of space behind the motor.

Whats the weight of the disc? That needs taking into consideration before you decide on motor/gearing.

[Revsmin]

At 150mm diameter, 20mm thick, about 1.2kg.

Single tooth, 5000rpm would give you the reliable hits your after... with a disc so light id aim for 2:1 for a quick spinup.... running a big 6s pack for drive and weapon...450kv motor ish would work well, and give out some decent impacts.

Cokes better

[Mouldy]

Or if you want to use the sk3 4962 530kv youd be getting around 5500 at the weapon. Wont be the spinner to end all spinners but it will be good... with a robot like your design its all about balance...to much energy in the disc and it wont drive very well and IMO a good drive is more important than an overpowered weapon

IMO a good drive is more important than an overpowered weapon

Says the man who built 720 XD

[Mouldy]

Just went to show this year though. Kept loosing because my drive kept failing lol

What i mean goes for vertical discs more than drums... they have more of a difficult time trying to turn without gyroing which allthough looks cool i imagine its frustrating to drive.
