Re: Freewing ME 262 The first Jet of WWII

Starcop,
The 262 is also my favorite EDF, and as Rich Baker says, "Its the best flying EDF out there". I have dozens of flights on mine with very docile and predictable flying characteristics but one does need to heed to Its slow flight envelope and to the difficulty in flying out of a stall, ( you better have plenty of altitude ).
The cg seems dead on with a 5000 pack strapped all the way forward. The only incident I had with mine was on takeoff I rotated and it instantly pitched up and started to go inverted. I had never had a problem before and was very surprised to say the least. Inspection of all control surfaces found all to be intact, but noticed the Bat pack was strapped about 1" back from the front firewall. Subsequent repairs made and numerous flights later have never experienced this again. The only logical cause would be due to the cg too far aft. I normally mark the bat bay in all my birds for placement of the lipo, but had not in the 262, I was flying 4 birds that day, and likely just mistaken the cg.

The 262 is one of the best EDF's on the market, but just make sure you understand Its flying characteristics re slow flight stalls and cg.

Starcop,
Thanks, I will try a 6000 Bat. in the 262 and SU-35. I am at sea level, so it should have a noticeable increase and duration. By the way, how does the SU-35 fly? I just maidened mine and w/o flaps notice landing speed is pretty hot, does this bird have a decent slow flight envelope?

Re: Freewing ME 262 The first Jet of WWII

My Su 35 does not have flaps. I do NOT use TV on landings. I will say that the landings are a slow affair I have my CofG another 10mm aft of that shown on the plans. I can land nose high as a result of the LE cuffs (extensions) (AKA; LEX). Again I use about 20% power on landing. If I get the nose a bit too high all she does is rock a bit like a delta wing would.

Now my landing style is NOT a dive for the runway and hope I flair out before I hit the ground. I make long flat slow power on approaches. I then cut back the power and pull the nose up as she slows down. If I have the right balance of power I run out of elevator as the mains touch the ground. I have landed with too much power and hit the tail pipe before the mains!

See my posted review under the Su 35 for some more details on my set up.

Remember that the CofG posted in the instruction are for the first few trim flights. Once the model is somewhat trimmed push back the CofG to realize the full potential of the model.

Re: Freewing ME 262 The first Jet of WWII

Matt, I'm not sure how far back you are going. I've had a lot of success with the old Robbe Rojet fans in the Robbe BAE 146 and Robbe Gnat. This was back in the days of round cells. Now true, there was a huge performance jump with the introduction of the WeMoTec fans and Lipo batteries.

As you are an employee I'd like to ask you to push for larger batteries. This is the one component that I have to go elsewhere to source. I like that MotionRC has many of the upgrade components I use, like the ZTW ESCs and Castle creation SBECs. With the addition of larger batteries MotionRC would become my one stop shopping center.

I too fly SU 35 with TV. I just find that I don't get the fine attitude control I want during landings with TV on. I may need a more advanced radio to tailer the TV mix.

I noticed that the SU-35 has about 80% the speed of the Me 262 yet needs about 30% more power (has a much shorter flight time).

All the best,
Konrad

Re: Freewing ME 262 The first Jet of WWII

I'd like to see larger capacity (mAh) cells, maybe 6000 mAh or 7000mAh cells. (Am I correct that the Admiral 5000 mAh is the largest cell MotionRC sells?) With the product line MotionRC carries I too see little need to up the cell count past 6 cells.

If the customer wants to go with a higher voltage lower current draw system this is beyond the scope of what MotionRC deals with. This usually means new motors, ESC and SBEC. Kind of defeats the point of the plug and play philosophy of foam even if staying within the same power constraints that the airframe was designed .

All the best,
Konrad

Re: Freewing ME 262 The first Jet of WWII

We are now getting into the Heli market and the KDS 7.2 uses the 6s batteries, you can always run in series to increase the juice, but watch your ESC and motors to be sure they can handle it. I can not offer any recommendations as to how you do that, that is solely on the customer.

[Konrad]

Re: Freewing ME 262 The first Jet of WWII

True, but balance often becomes an issue with the limited space in the fuselage to use 'parallel' packs.

I don't think we really need higher voltage packs (6+s) for the 70mm twins fans or the 80mm fans. But larger capacity cells would be much appreciated (higher mAh ratings).

I'm using 4800 mAh cells in my 8 cell Trex 600. This was a nominal 6 cell heli. I upped the cell count and lowered the current draw to gain duration yet maintain the power (watts= V x I) needed to perform, within the limits of the airframe.

So are you going to offer larger 6 cell batteries than 5000 mAh for the KDS7.2?

All the best,
Konrad

Re: Freewing ME 262 The first Jet of WWII

Here is a short video of the Me 262 at 5k to 6k feet altitude (Denver area). Sorry for the small dot on the screen this was taken with an old I-phone. This was only the second flight. The pilot wasn't comfortable yet, still hadn't tested for warps or cross trims. As you can tell the CofG is still too far forward.

it will only waste a few minutes of your life.

Re: Freewing ME 262 The first Jet of WWII

That sure looks like a nice field your club has, although Im sure you have plenty of downtime during Winter in the Denver area. Also fun to see all the different fields and beautiful countryside from other pilots submitted vids, Keep em coming

Re: Freewing ME 262 The first Jet of WWII

Actually it only snows when there is a nationally televised game <smiley image="smiley_what.gif"/>. Winter is a great time for edf as the colder denser air makes for better thrust (lower altitude density) kind of like at sea level.

All the best,
Konrad

P.S.
I was a guest at the Arvada field. My home flying spot is in the San Francisco area.

This is a problem with MotionRC in that they will not allow me to ship to my family home in Denver and send the bill to my home in SF. I have to have my dad buy my toys when I visit (really a stupid situation). In the case of the Me 262 my long time friend Matt had to make the MotionRC order. He was also the pilot in that video. I was the peanut gallery.

Re: Freewing ME 262 The first Jet of WWII

"Crowded"
Another benefit that often isn't mentioned is that when flying these Freewing twin 70mm fan models the 'guys' all seem to want to land and watch the model fly. I constantly get requests to wait, while the guys land their planes. Once the air is clear I then take off with the whole sky to myself!<smiley image="smiley_beam.gif"/>

[Aros]

Love this jet. I need to get another one.

[crxmanpat]

As soon as MRC gets the new upgraded motors/fans in stock, I'll be upgrading my current one from 6-blades to 12-blades!

Re: Freewing ME 262 The first Jet of WWII

Hello CT, I noticed that with Thrust Vectoring you can really bring this Jet in slow. I've always used thrust vectoring when I fly, so I'm not sure of the speed has I not used it. I does have a lot of straight line speed, so I'll have to experiment soon to see what it does. I now have a road or black top runway, I've been landing in the grass for years now. It's a whole new ball-game on the road, it takes a lot of time to slow down. I do have to say, these EDF Jets are a blast to fly! I'm really enjoying the new found fun. Thank you all for the information and your experiences, I love to hear about the characteristics to watch out for. I've seen a couple videos of guys who tail spin into the ground, I thought; how the heck does that happen? Well, it's all aeronautics and understanding wing load and conditions. Not sitting in the seat, you don't have that under your Butt experience. So, any new information is great with all these new Jets. I now have the Freewing F-86 Sabre 80MM. SU-35 Twin 70MM, F/A 18E Hornet Ver. 2 90MM. ME-262 Twin 70MM and the YF-23 Twin 70MM. Much more to come!

Matthew

Is that an LX single 70 F-35? Looks pretty nice! I forgot about that one.

Freewing needs to make a nice 80mm version of that with nice gear... That'd be great!

What is this person talking about??? Wow, talk about non-sense over bearing awkward statements. This is "Fun" RC aircraft hobby not rocket science or factoid annoyance class! I had more fun in the dentist office than with what this person writes here on the website. I understand there are people who need help, I truly hope this person can get some counseling. Life's too short, enjoy people and have some fun in what this hobby is all about. Cheers! Matt

Matt.........Don't worry about him. That's the person whose been banned from the Squawk three times.
How did you miss the nemesis of our community known as Konrad - KJD - Aspirin ? ? ?

Conducted the erstflug of White 2 today! What a nice jet! Can't say enough good things about how it looks and flies.

I inadvertently flew over the pit area while getting used to the turning characteristics. Another reason I like to do first flights alone or with the fewest spectators possible.

I did have to fix several issues right out of the box, mostly having to do with over-torqued screws in wood. I basically had to fabricate replacements for the rudder servo mount, belly hatch mount, and nose wheel steering mount. Also had to remove the engine pods to undo tangled wiring. I replaced the plastic clevis on elevator with a Freewing ball link.
There was an issue with the trailing edge of the wings at the flaps being warped. I solved that issue by making a jig and cutting out the flaps for full flaps instead of the inexplicable split flaps.
Still can't figure out why they put split flaps on her. But she looks good now.

Best looking and best flying jet I have purchased so far.


She flew great with ZERO trim. I am running the CG at the back end of the range. Hands off straight and level flyer. Sweet. This one is going to be my new favorite.


The weatherman missed the mark today. Turned out to be overcast, 49F, and winds light and variable. Great weather to fly the 262 in!

[Grossman56]

Great to see Seaviper, just the fact that your field isn't covered with snow is awesome! Looks like she flew great, hard to believe it was a maiden, but awfully nice when they go that smooth isn't it??

Grossman56

[seaviper]

Yeah, I was shaking in my boots literally as it was 49F outside. But the handling was a pleasant surprise. I really do like this EDF model. Not to mention that the 262 is one of my personal favorite planes of all time. I have an autographed photo of one of the original instructors, Herr Franz Stigler. The USAF threw him a shindig because of this incident.

Anyway I forgot to mention I was flying her on an Admiral 6s 5000. One of the new ones. Very nice.
