Official Freewing 70mm Twin Me 262 Thread

TKS, I waited so long for this plane and someone posted a similar mod I just had to do it, such a beautiful airframe.
I did recently reach out to Keith at parkflyerplastics to see if he would make one but sounds like demand might be too low for him to take it on. Maybe if he gets allot of calls for it, it would make for an EZ redo if the thermoformed canopy was available. Looking forward to some better weather, hopefully fall will bring better conditions.

Mine is ready to maiden tomorrow, there were no control throw recommendations in the manual. What are you guys using?

[mr.frankenjet]

Brandon Moon posted these, it's what I started with. Limit ele on this one, too much ele and bad thinks can happen. Good luck and happy landings

Here is a good point to start with...I recommend using low rates first. Here are your awaited and requested "Nuclear Launch Codes" The throws for the surfaces: Ailerons - H: 7/8" L: 5/8" as measured at the ROOT of the aileron (inboard edge) 30% expo on both rates. Elevator - H: 3/4" L: 1/2" as measured at the fin 30% expo on both rates. Rudder - H: 1" L: 3/4" - 30% expo on both rates (or No expo if desired?)

[dkalwishky]

I checked my rates that I guessed at against Brandon’s numbers and it was almost a perfect match. :)

Did anyone glue their wings halves together? I haven’t yet, trying to decide if I want too or not.

Did yours have the warped wings where the flaps don't close flush with the TE? I'm still undecided about this one as I've already got a couple other planes with split flaps that don't close nicely. Always wanted one but the Dynam offering just didn't look like a quality product. This one looked to be a better product but ................. that post about the nose snapping off when landing on grass is also a little concerning.

I think the Freewing 262 looks a LOT better than the Dynam product. And this new one is even better with the new camo and motors.
Mine's due to arrive today so I will post what the wing looks like.... the older one's flaps fit perfectly.

When I flew the older one the first time two years ago, the nose broke off on my first landing. (partially because the model was nose heavy) It was a clean break in the foam which was easy to fix. After I installed CF in the nose on each side, the repaired model was fine for dozens of flights. When I put the new one together I'll post a few pictures. I don't remember exactly where I put the rods.

One of the inboard flaps had a small warp to it. 30 seconds of massaging it with my fingers fixed it and they all close tightly.

Please do, I'd like to add CF rods to mine.

Good to know. I think I'll pull the pin on this one and just add braces to the nose section.

Man this plane is well done, the new paint scheme looks great and there's nothing like the way FW packages their planes!

Here's a pic of the left wing on mine, right out of the box.

Yes you can see that there is a mild warp on the TE. Its not bad (unless you take a real close-up look from this angle, which makes it look as bad as possible!) and most of it is the flap. I am sure with a little massaging it will be pretty simple to gently bend it into shape like dkalwishky mentioned.

Or perhaps this winter I'll cut the flaps out and make them "full" flaps instead of split flaps. We'll see.

[rifleman_btx]

Oh yeah that looks very very goood!

That isn't bad at all, looks about like mine was and it flies nice and straight, I'm sure yours will to.

This is the new paint scheme on the Freewing ME-262 and tonight was the maiden flight.

Two things I didn't care for with this plane are the way the servo cables come from the wing to the fuselage where the receiver is and the screws that are used to hold the fuse to the wing, they are self taping screws and not bolts. Hopefully assembling and disassembling the plane over time won't strip the screws mounts.

I am using a cable bundle with MPX connectors so I only have one cable to plug in between the wings and fuselage, this allows me to deal with one cable instead of four and will make assembly / disassembly much easier. I'm using the same setup on the 1600mm Spitfire and it works really well.

When I assembled the plane tonight the gear was up, once together I dropped it, the nose gear came down but the mains did not. I retracted the gear and dropped it and then all three came down so I didn't think much of it.

I'm using the new style Admiral 6S 5000mAh battery all the way forward. The takeoff was smooth and quick, the plane flew really well with the books low rates, minimal trim was needed although I think I was nose heavy as when I went inverted it took almost full down elevator to keep the nose level. I also noticed in turns that I needed a bit more up elevator than I think should have been needed which further leads me to believe the plane is on the nose heavy side. Rolls and turns were nice and smooth, this is a really nice flying plane..

During one of the passes I noticed that the mains did not retract, I tried cycling them a couple of times but to no avail. Once on the ground I tried them and the mains would to budge. I'll get the plane on the work bench and check it out to see what's going on. They worked up and down several times a few days ago when I got the plane first assembled.

Landing was really easy with this plane, there were no surprises but I felt as if I didn't have enough elevator for landing so I kept the speed up and elected to land in the grass since it would help slow the plane down once on the ground. The video blurred out while on final then corrected itself once I was down.

This is a solid flying plane and I cannot wait to get more flights on this over the next week. I remember a flight video where Pilot Ryan said he started with the battery all the way forward but then ended up moving the battery back 1/2" so that's what I'm going to do next time.

These observations leads me to take note of something that has me scratching my head a bit. On the RC Castle site, they are selling the V.1 of this plane and by all counts, the only difference between it and the V.2 is the paint scheme. The V.1's posted recommended battery is a 6s, 3700mah. Yet, the V.2's posted recommended battery is a 6s, 5000mah. If nothing else on the plane has changed, then one would deduce that the placement of the bigger battery should be somewhat aft of where the smaller battery would go. Even at 1/2" back from the "all the way forward" position, this still seems like it's too far forward. Could it be that the recommended CG is wrong?

This thread is the Freewing... I had the Dynam.
I suspect the same thing is gong on here.

At recommended CG, the Dynam did not like inverted at all, dropping the nose with full down elevator (which is supposed to hold the nose up when inverted)

I checked CG vs MAC and it was WAY noseheavy vs the standard rule of thumb 25% to 35% MAC.

Pushing CG back to 30% improved inverted but didn't cure it.
However this created an issue where low speed and high throttle would pitch up the nose uncontrollably.

I had a chance to discuss Me-262 characteristics with pilot of one of the full scale reproductions.
The nose pitches up significantly with high power at low speed. They CAN NOT apply full throttle before the airplane is well off the ground and has built up speed. (especially with the higher power engines in the reproduction)

The models are recommending CG way forward to prevent someone causing the airplane to do 3/4 loop on take-off when using full throttle.
Compensating for this, the horizontal stab is mounted with significant "decalage" (different incidence of main wing vs tailplane) in order to allow you to keep the nose up (upright) at less than 3/4 throttle.

Nose heavy and the decalage will result in the airplane not being capable f sustained level inverted.

I modified the Dynam with in-flight adjustable horizontal stab incidence (like the full scale has) and with the adjusted CG, was able to do an outside loop.

Let's see if this will work. First, the picture must be in its own tab/window and not a link to the webpage it's on. IE, ask to have it open in a new tab/window (right click on the picture). Then copy the URL. Then use the "picture" icon in the formatting line above and paste the URL into it when the box appears.

Mine came yesterday. Only had time to unpack everything just to check condition and take inventory. All bits were present and accounted for. Quality was excellent and the dreaded wing warp at the flap trailing edge was next to non-existent. Got it all put together today, bound up, tested, calibrated and looking real nice. Will put in a couple of re-enforcement pieces of wood to safeguard against the nose coming off should I have a less than smooth landing. I was going to Mod Podge it before putting it together but the paint and decal quality appears to be very good. I'll maiden in a couple of days and will see how much abrasion from the grass runway will affect the paint. I can always Mod Podge it later is necessary.

That's where yall have an advantage up north, less heat, less chance of warping

I wish it was true about the heat. Yesterday, we broke the record for this day EVER in this city. It officially (at the airport) got up to 36.5C (97.7F). It got up to over 40C around my house. Who knows how long the box sat in the UPS truck while it made its round before getting to me.
I can't imagine what people in Europe go through every year for weeks. Most of the fans and small air conditioners are sold out in the local stores. We're just not used to it and we're a bunch of wimps. :Sick2:
