I haven’t been able to find the spec sheet on the new power system. The manual available is still the one from a couple of years ago. I bought the version that was supposed to be the 3530-1750 Kv w/ 12 blade. I actually received the 3530-1680 KV with 12 blade. 80A esc. The improvement note in my manual rates it at 2500g or 88.18 oz.
Does anyone have the improvements notes for the 9 blade version?

I just picked up one of these from an old friend, and it appears to be the older 12 blade version. The ESC has the heat shrink cut off where the label is, so I'm not sure if this is a 4s or 6s bird. I'm leaning towards 6s, especially since its underpowered, but it's hard to know. It powered up fine and took a quick burst of full throttle on 6s, but continuous who knows. It was bought prior to 2016, don't know the exact date.
Does anyone have insight? I'd appreciate it! Lucky for me it came with a flysky rx and some no name stabilizer/gyro and I could bind it directly to my Jumper T16 MPM. A bit concerned with the range, so i may put a crossfire 915mhz control link in...
If pictures would help, let me know :)

Originally posted by xviper View PostIf it's an 80mm fan, it'll be a 6s system, so if you put a 4s battery in it, I'm surprised it actually flew. Those early 80mm Sabres, even on 6s, were quite anemic. It likely also has the 80A ESC in it. The newer, "high performance" ones, have 100A. Do you know if it's an 80mm fan or is it the smaller plane with the 64mm fan.
I suppose without taking it apart I can't really check if it's 80mm? I measured the outlet on the back of the plane and its right around 64-65mm on calipers. If I open the calipers to 80mm and put it near the fan it does look to be 80mm and not 64mm. I'll attach a picture, not sure how helpful it'll actually be. Looks like I can pull the wing off with just four screws.1 Photo

I wonder how hard it'd be (and the cost) to upgrade it to the newer version, especially if it gives me longer flight times. I wonder if anyone has thrown a full blown flight controller in and flown it FPV. Maybe I'll try it out.

Going to upgrade my old Freewing F86 with the old 12 blade outrunner motor in it to the new 80mm 9 blade inrunner motor I take it the new 9 blade inrunner will fit into my old F86 fuse and by what I have read in this forum it should help my dodgy take off from my grass runway ,it only just get airborne with the old 12 blade outrunner .Hoping the new 9 blade inrunner will help there

Thanks xviper ,never gave the esc a thought . I have an esc from a crashed FMS Hawk ,it is 100 amp with a 8 am BEC so that should be OK .Yes I have brought the complete 80mm inrunner set up from Motion RC .Let me know if you see a problem with FHS Hawk esc .I am not great on electric but I am sure the FMS esc should be OK to fit in the F 86 80mm inrunner motor

I would bet its an 80mm because I found a video of the old owner flying it and it didn't look too bad, although it was using concrete for a runway and not grass. To clarify, I did not fly it on 4s lol I just read somewhere about there being a 4s version and didn't want to throw 6s at it full throttle on launch without knowing.
