Official Freewing 80mm EDF F-86 Sabre Thread

[Syntha]

I think I'm going to plan to get the 4500 MaH Graphene V2 ones, they seem to be better than the extreme SMC batteries, performance and weight wise. The 4500 MaH batteries are 588 grams, and I think I'm going to try them in the F16 super scale, since the flight time for those is usually limited to max 4 minutes anyway. People are saying to stick with 4000-5000 MaH for the F16

I want to buy the SMC 5300 MaH for the F86 12 blade out runner (non high performance). Do you think it would work well? Its about 685 grams.

Those will work as good as anything BUT, you might want to aim for one that is even lighter, maybe below 600g. Remember, my 725g 5000mah runs the HP really well. A battery in that size range might not be as good in a non-HP EDF. However, it will still be more lively than what you’re used to. In any case, those 5300 SMCs will serve you really well for when you get another 6s jet.

PS. If you are going to get them, get them while they have stock. I’ve been told that supply on quality LiPo’s is and will continue to be limited. I’d love to get some but shipping from Florida to me is complicated and the only Canadian dealer has very limited stock on what I need.

Yeah, I just purchased a second hp one to paint like an FJ Fury...since it continues to snow and rain here. It'll get dry and smokey soon enough so I'm not complaining loudly. It's refilling the reservoirs.

I really need to get some of the SMC batteries to try, they sound worth the while!

[xviper]

No worries, it's common issue if a plane seems excessively underpowered.Which your description sounded that way. I'd try lighter batteries and fly it! Switching later to the high performance is easy enough.

Indeed! I started with the lesser powered version of this plane. It was "OK" but could barely get out of its own shadow. Then I upgraded the ESC and EDF to the inrunner and the difference was remarkable. I could actually fly it with the drop tanks on whereas before, I wouldn't dare use the drop tanks as the drag was just too much.

Thank you for the ESC calibration, I did not know ESC's could be calibrated.

I bought the 6000 MaH 818 gram batteries because I want to make sure I wouldn't run out of battery for too long, but it sounds like it makes a small difference for the motor I have due to it taking a lot more power to keep my nose up. Ill take a look at getting 4500 MaH batteries, and maybe I can use my 6000 MaH batteries for my F-16C super scale. That plane should be able to fly with it well.

I wouldn't count on that battery working any better in your F-16 (see my previous post). "No-name" brand batteries can sometimes be false economy. Take a look at this real world load test and decide which brand you should be targeting.

Oh, you can search YouTube for a "how to" on throttle calibration.

[xviper]

An 818g battery is pretty heavy for this plane, particularly if you aren't running the Hi Perf. inrunner. I use a 5000 Gens Ace 725g battery on the Hi Perf. fan and it's actually very lively. With the less powerful outrunner, you might be better to use a much lighter battery. Also, that Hoovo LiPo you're using is likely not giving you more than 25C. Find something that is light but will give you a "real world" C rating of closer to 40C. Most brand name LiPos stating 70C or more will give you that 40C you need for a jet. (Hint: SMC - their 40C Lipos actually give you about 38C and they're light.)

As your saying, a lighter battery like a 4000. You did say 'any ideas' so maybe the high performance motor, but it should fly better than it sounds on your motor. So did you calibrate your esc?

[Syntha]

My F86 is very, very stable flier, however no matter what I’ve done, I need to use about 75% of my elevator servo to keep the plane flying level. CG is measured at 180 cm, exactly where the CG needs to be, but I think the problem is the batteries I use cause the plane to be too heavy. I have the regular F86 80mm, not the performance one. I know it’s not the performance f86, but the plane still flies sluggish and slower than my propeller plane.

I use a 6000 mah HOOVO 6S battery, weighing in at 818 grams, 25 ounces. Should I get a lighter battery? Nothing else has been installed in the aircraft, and battery is pushed up as far back as it can possibly go, and i don’t have any expos on my controller. Any ideas to try and lighten up the aircraft or make it fly faster?

Sharing a video flying formation/dogfight with a Sabre at an interesting field:

Got it... I already bought mine with the upgraded power system so I think this should be in mine already...

No need to "think". Look up the tailpipe and you can see if it's an in- or outrunner. If it came with the inruuner, that's the only motor there can be in there.

On Motions site there is a search window. Type 1920 and enter and it comes up. Here is a link.

A friend did a gear-up landing into the grass and broke the cheater grill on his F-86, so I made a replacement for him.

I have posted the STL file at https://www.thingiverse.com/thing:5394295

What is the best option for upgraded landing gear? My tires developed flat spots, and the nose gear and main gears have all crapped out on me at least once (probably some hard landings ;).

[socalengineer]

ob1 i installed the flightline hp 1920 fan and fly it off grass with no problem its really a powerfull 9b fan

Could you link to this fan?

[socalengineer]

What are the longest flight times (and which packs?) you all are getting with your Sabres? I'm trying to set up an FPV jet platform and I would like at least 6-minutes at moderate throttle. Does this beautiful jet cruise at partial throttle?

Well if you fly FPV, you have added weight from the FPV gear so keep that in mind. I fly with a 4000 pack and get 3-3:30.

[Laury415]

Laury415 Which retract unit did you use as a replacement?

It was one I had in my spare parts. It was a couple mm wider then the original, and built stronger.

I think this one will work: flight-model.com, PZ-15090SN
total price with shipping to the US is less then the original replacement from Motion RC.

I had a couple flights with it today, worked great.
