Great info, Soma. I just ordered SS 2212 980Kvs for a new FPV quad. Will be looking forward to your tests on that. Hope you can include HQ-Prop data too.

Hey mate, great to see you here. As usual I've been meaning to email forever!!!

Prop ranks for this test are being swelled as we speak. The only ones I need not on the way now are some genuine Graupners. Which HQ Props do you want to see? Hopefully their 10x5 & 11x5 will be along soon. I would like to try their 9x5 triples but I don't have any, I'm waiting for the new props to get an order from Feng. The existing 9x5's will be a bit small for this motor I think.

BTW I've realised my stoopid mistake with the RPM sensor. I calibrated it by the stator arms not the magnet poles! Noob mistake But all the data should be fairly close. I tried dividing by 14 and multiplying by 12 and it worked out well. All the percentages of free RPM remain correct and they're the important one. DOH! I'll add more props to this motor test and adjust figures then.

I'm leaning toward 10" on 3S, so the 1047 and 1050 if there is one would be good in comparison to the 10x4.7 APC MRP.

Its good your frame will clear 10" props mate. That seems to be the FPV zone for the 2212 980KV. 10x4.5/4.7 MR/SF style on 3S, or 10x5 Graupner style on 4S. I think the cruising efficiency might be better at 10" SF on 3S, right where you're aiming.

It seems for a light weight acro quad it could pull 10x4.5MR/SF's or 11x5 Graupners both on 4S.

I'll test as soon as possible

Hey, have you seen these?

I haven't committed to a frame, yet. Was hoping for a new alternative from down under , but it looks like I might have to settle for a Flip FPV. Or a BlueSky H-frame. Or a QAV. Or a Quadromax. Or a Spydex...

I hadn't seen that ESC. Apparently intended for installation in a tube?

That's part of the reason I've been meaning to email I'll be in touch soon There's a few things under way but making slow progress on all of them.

Yes the new afro will fit inside 12x12 alloy I think and probably 16mm round CF tube, maybe not 12mm though.

Those skinny Afro ESCs look cool, but I can't imagine they would stay cool being stuffed into a square or round tube though.

Soma,

Any luck finding the time to test the SS 2212 980kv motors?

Hey mate, Just waiting on some props I've ordered, I also want to get some APC MR 8's & 9's + some genuine Grapners. I have most things on the way... then I'll need to find some time

I'm thinking how good those Skinny Afro's would be on top of a 10mm Alu arm or 12mm timber. Not a big fan of ESCs in confined spaces myself.

I wish I did mate, but my project was for a 400mm quad only. I'll need to revisit that another time when I can afford to buy some 12" props for testing.


Cheers!

Anyone got rpm and current data for this motor turning a 12x3.8 and 11x4.7 APC-SF props on 3S battery?

Hey mate, I have a couple of 12" props on the way to test on 3S. I don't think I have a 12x3.8 though sorry.

I do have APC 12x4.5MR prop on the slow boat from Tower Hobbies. Last Tower Order with cheap international shipping took 6 weeks to arrive though

I'll also be adding HQ Prop 11x5 & 10x5 data asap.
