LX B-2 Spirit 64mm Twin EDF

[Bearcat]

Mine has been good to me most of the time except the times I ran off the runway and it rips off the gear doors :-() BH and GH both sell this bird still which is good news. The bad news is finding a battery that actually fits in this thing. I was using a 5000mah 25c 4s Turnigy battery which it appears that HK no longer sells, finding the right weight and length is a major pain in the rear so I have to measure and compare batteries until I found one that works.. Graphene Turnigy might be a good option for me but somebody must make a battery that fits this bird.

Run to the relative safety of the SR-71! Good decision. I love the B-2 but yikes LX needs to *listen* and improve several things on their bird otherwise it will continue to wallow in its current kiddie pool in the corner while the rest of the the EDF guys throw a tasty ribs-filled BBQ.

The joys of owning a lx model... :-S lol

[Aros]

I might buy the kit though...Maybe I will just transplant the power setup into the kit, and get some better gear in her....Ah, the heck with that. Blackbird it is. LOL

[F106DeltaDart]

I understand that feeling. I got to a similar point with my LX F-4, was just more trouble than it was worth.

[Aros]

Thanks, yeah she's repairable technically-speaking but I'm at that fatal point where I don't care enough about the airframe anymore to expend the effort. This bird is not meant to be a hand tosser with all the ballast needed in the nose. I agree with you, I would love to see Freewing come out with a superior version with the proper gear. If they did, this could be a fantastic jet.

[F106DeltaDart]

Sorry to see that Aros. Hopefully eventually freewing will make one that won't have the abundant problems that this one has. On the bright side, the airframe still looks decently fixable. Epoxy on the outer panels and add some carbon spars and it could be made to fly again, if you aren't tired of dealing with this airframe. Also that SR-71 should be ballistic with those fans, can't wait to see it.

[Aros]

We are gathered here today to celebrate the all too short life of Aros' LX B-2. After installing the twin 64mm 12-blade power system, the first hand toss was unsuccessful falling flat to the ground due to excessive weight and low speed at toss. Second attempt went haywire and she torque rolled into the dirt with spectacular fashion.

To make matters worse my Mobius crapped out on me today so the footage did not survive. :@

The power plant will be transplanted into my LX SR-71 which weighs MUCH less than this fatty McButterPants did.

[Aros]

Good advice! ;)

[xviper]

Oh, and if you really like it, buy that last one BEFORE you post about it or I may snap it up first. :p

[Aros]

Will do for sure. Hopefully this weekend...

[xviper]

For sure on the vid and your impressions of the new power plants. This plane is not high on my list but it is still of interest to me. (I'm a bit leery of LX products.) If you shout out its praises, it could move up the list very quickly.

[Shirty]

Make sure u get some vid mate! ;)

[Aros]

My buddy helped me insert the new power plant in her...Sounds and feels like a huge upgrade over the stock setup. Can't wait to find a dry day to re-maiden!

[xviper]

I'm not sure I will buy one now. I still don't know where I'm going to store the P-38 when it gets here. I hope to sell a couple of planes soon.
That's a pretty price but I'll still need to add in all the bits and pieces to make it fly. I need a high power system for grass. I've got retracts that will work and I can "bomb proof" the mounts for them.

[Aros]

I actually removed the gear already but I can see your point there. I decided to discard the added weight and removed them however. My power system arrived so I am looking forward to getting it all hooked up this weekend. Hopefully I can shoot for another hand toss attempt if weather permits.

As for the wing tips, those are called "drag rudders" (aka "clamshell rudders") and they allow drag to one side of the B-2 or the other for yaw authority. However, for the LX B-2, it flies the most stable with the drag rudders both open equally.

They have kits for sale at a good price here:

Even comes with the retracts (although the nose retract is worthless and will need to be replaced...I would actually replace the entire gear/retract set myself).

Just don't buy the last one as I am going to want to get one myself! LOL

[xviper]

What about taking off with gear down and then belly landing? I do that with a couple of planes where the landings are rough and not very pretty looking. Belly landing makes it so much easier and saves the gear.
I have the LX A-10. First landing and all retracts broke. They've replaced by retracts from a Freewing SU-35 and have been working perfectly. I've also replaced the fans/motor/ESCs with high thrust units. The foam is very soft and porous but at least the thing flies.
I've always wanted the B-2 but with my experience with the A-10 and everything I've read, I've resisted. If it were cheap enough, I'd get one and immediately replace retracts and power plants.
PS, what do those things on the wing tips do? I'm talking about those split control surfaces. Yaw control?

[Aros]

I ordered those 64mm 12 blade units and two ZTW 45A ESCs...Should get them sometime this next week. Looking forward to rebuilding her and seeing if she excels with the new power system or if a new airframe is necessary. I will keep you posted.

[rc4ever]

I am planning on putting these in my B2.

Hi Don, nice to seeya here....Heck we missing the Balanced EDF units, i personally have 5 units installed in 2 Stingers a A10 and a HK t45. they are the best.

My experience with flying wings is that as the speed increases one needs to add forward stick (down elevator). This is inherent in reflexed airfoil. If looking to onboard electronic stabilizing, I wonder it using a speed sensor, form say a telemetry system, could be used to trim this out automatically as the speed changes.
