Xfly Models B1B Bomber 70mm

Boy that’s a bummer f106, I typically am skeptical of gyros but I do use them in a few planes and they work well, the combination of gyro and system or mode configuration has made me a bit uncomfortable with this jet. I have been putting off flying it. Not very characteristic of me , I am a roll it out and go guy. when other seasoned pilots have issues with new products I pay attention. 🤔 hmm what to do…..

Aros I've used tape with XT's but worry about heat and adhesion, so I've also used zip ties in between the leads to keep em together.

Is it not possible to swap gyros with a higher quality one with adjustable gain?

My buddy's comments post maiden:

"So I flew it. Flies good, but the gyro makes it feel crazy. I was fighting it while landing. Didn't fly it again but when I do I will have the gyro turned off."

My EC5 to XT90 adapter doesn't arrive until tomorrow and I will be gone by then headed to the filed which is a 2-hour drive. So besides gyro off, no wing sweep, I was planning on flying with my EC5 plugged into the XT90 and adding some Gorilla Tape for insurance. Is that too risky? If so I will just wait for another time.

Unfortunately the gyro has no remote mode, on/off or gain control, so once you take off with it, you're committed. Hmmm...

So what's your thoughts on the wing sweep/elevator issue?

Need more data. "Once is happenstance, twice is coincidence, three times is enemy action"; Goldfinger, in "Goldfinger" by Ian Fleming.

I'd like to hear from Jeremy.

Having said that, the gyro does not fill me with confidence, for reasons that I explained on another forum.

[Aros]

You're assuming I'm not a helpless monkey that runs screaming from electronic tools. LOL! It really does set it off nicely. So what's your thoughts on the wing sweep/elevator issue?

[kallend]

Niiiice!

Thanks.

A single Arduino drives each of the four tailpipes independently. With decent electronic soldering skills you can put one together in about 2 - 3 hours for under $25 for parts. It will drive pretty much any LED lamp from 8 to 25 volts. I used Yorkim amber turn signal lamps in this one.

No charge for full instructions and the Arduino code.

Yeah as I said on RCG I'm really sorry to see that F106DeltaDart. I have a 2 hour drive to the club tomorrow and I am praying the 2 hour drive back home Sunday doesn't have the back of the car look like your photo. I was just going to post here to tell folks it appears there is an issue in wing swept mode. I will absolutely NOT put mine in wing swept mode on my flights until it can be determined the cause and the solution. Sucks you had to be one of the guinea pigs my friend.

F106DeltaDart, a cryin' shame. my friend. Looking forward to a final debrief. Condolences, LB

Well, to say the least, this was not how I was hoping the maiden flight would end… Spent hours setting things up exactly per Jermey’s videos and thought I’d give the stock flight controller a shot for the maiden flight and maybe bypass it later. A word to my fellow B-1B pilots, approach flight with wings swept very carefully, and be ready to bail out of it at a moments notice.

The aircraft was configured with a 6S 5800 battery towards the aft side of the battery compartment, balancing at intake lip per the setup video. Controls all centered mechanically, no trim or sub trim as per the videos. 2 RC geek Center burners were also installed.

The take off was uneventful, and it flew pretty well with wings out. Maybe a bit tail heavy in that configuration, but not bad. The stock gyro was doing a good job overall. 2 normal patterns were completed before I was confident to try sweeping the wings. I swept the wings on downwind, and attempted a turn to stay in the pattern.

This is where it all went wrong. With the wings back, I found myself at full up elevator just to maintain level flight, and heading out towards the lake at the end of the runway. I gently attempted to coax it into a turn, with a bit of elevator, aileron, and rudder, but it was bleeding altitude. I then tried to get the wings back out, but by this point it was diving out of sight behind the tree line. Found it 10 ft away from the water, just as you see on the shore.

Pretty much everything in the nose was destroyed, including the battery and my 9 channel Spektrum receiver. The aircraft itself is pretty much a write off. Only the far aft tail section survived intact.

Niiiice!

Testing the Do-It-Yourself afterburner. Four independently driven tailpipes.

Man she's bigger than I expected! Put her together on my lunch break. Pretty easy build. I forgot it has an XT90 connector (all my 6S LiPos are EC5s) but I can still connect the EC5 to the XT90 just to program and get the settings set up. Adapter ordered so the maiden will have to wait some other weekend. Beautiful bird!

I can hear George Thorogood already!

[Aros]

Cool! Paint job?

[T- Elbert]

It’s ready to fly , weather dependent… but I feel a paint job coming on

[Aros]

Alright fellow B-1'ers...My buddy said we should watch these videos BEFORE powering this model up...

I'm going to watch these myself and suspend the build until I have a good grasp of the situation...

[Elbee]

She's a beaut! Here's my buddy's...

Aros, "Res ipsa loquitor" Best, LB

[Elbee]

As soon as I’m done being a responsible adult, this is getting built.

Ain't it the way. Best, LB

Does look really really,, really nice cant wait t hear how it flies
