Anybody know about adding doors for the nose wheel bay? I've found the stl files and I can get them 3D printed via an online service in either Graphite-SLS or PA12 (MJF) material. The latter is half the price, would it be OK or should I pay (a lot) extra for the SLS material? Also, how would I advance/delay the door open servo's?

[NoDirt!]

I really like your choice of markings, NoDirt! I remember building a Revell kit years ago and ended up modeling the exact same bird!

Cool! I thought I may be the only one that ever saw the Buzz Wagon. I like the yellow and wanted something different.

A visitor stopped by our filed a while back and took photos of some of the planes and put them up on his Flicker account. While looking through them I was surprised to see my Barney's Buzz Wagon in flight!

(I don't know why it's showing that pic all pixelated but I can seem to change it)

YAY! That worked! All ESCs now programmed and responding THANK YOU VERY MUCH.


The key in the video is to power everything up with the Throttle Channel unplugged from the RX. Then, do whatever it is you wish to do, such as put throttle stick high (for calibration and/or menu), etc, etc. Only then plug in the Throttle Channel cable.

Or, watch the vid.

Mikdys, thank you again!

I'm pleased that worked for you :)

This was my first multiple engine plane and, seeing how the ESCs can run with different settings, I always check the motors are in synch and have brakes off as a pre-flight check. I'd guess it is unlikely they would go out of synch or activate brakes without an external cause, such as a prop' strike maybe, but I'd hate to take off or land and find it going sideways!

Have you tried following the advice in this video (worked for me :) ):

I have searched to see if this is a known problem and I have not found anything.

Assembling a Silver B24. Everything going great except getting the ESCs programmed. I had all kinds of bizarre beeps and non-beeps and won't arm and run and so forth and so on, until I hit on the following:

If I unplug one multi-wire connector from one wing, and put a battery in only one of the main battery connectors (thus dealing with only one ESC at a time), that esc works perfectly. I can set the throttle range, I can go through full programming menu, etc, etc. It makes all the correct tones, per the Flycolor ESC manual, as you go through the menu, etc. When plugged in throttle low, it beeps correct number of cells, arms, and responds to throttle as you'd expect. In other words, it works just as you'd expect. Perfectly.

However, after verifying correct operation of each of the 4 escs in "separate" mode like the above... if I plug in the other wing's multi wire connector, then I am back to things like low throttle = no beeps at all, high throttle (as though you were setting range or programming) = different beeps from the controller in each wing, not at all like the menu beeps, often get repetitive beeps that just keep going about once or twice a second and never change, etc, etc. Almost random beep patterns. And, they generally will not arm or run.

Oh, all the other servos in the wings, flaps and ailerons, seem to work at all times, So do the ele/rudder/nose-steering. In short, all servos work all the time (that they are plugged in).

I've tried two different receivers, a Lemon 7 and a older DSM2 Genuine Spektrum 9 channel. Same symptoms with both receivers. I've tried the provided BEC and I've tried a stand-alone, regulate, 5V battery power supply. No change.



Summary: one wing's multi-wire connector plugged in, everything in that wing works. Both wings plugged in, servos are fine, but all the ESCs in both wings do not work correctly and behave very erratically.

Is this a known problem? Is it possible I have a defective Freewing controller (splitter) board? Is there any way to reset the Freewing board?

Thank you Hugh I appreciate the info concerning the delay issue with the flaps. I was also thinking of the sound system too with the size of her fuse. Great minds think alike!!!

Definitely put the sound system in and get the multi-engine pack, it really makes a difference as it has 2 sets of start-up sequences and does sound like several engines. It was a little difficult to put the Aspire card and the 2 transducers in, but the TT-25's with add-on heat sinks just barely fit behind the integrated circuit boards (near the fuselage openings for the wing wiring harness's) and the Aspire card fit behind the carbon wing tubes. A tight fit to be sure, but it does make it and keeps it away from the battery/wiring/receiver area (snug as a bug). As I said, I put it in both my Silver & Olive B-24's. I've attached a couple of photos if that helps. I hope you can figure out a better place, but this was all I could come up with. Good luck.

I also did a video of the engine sounds (which is not great quality-actually sounds better) before I finished out the cockpits/gunners and final painting which you can access on you-tube under: https://youtu.be/PhoFY59hrE4

Thanks Jerry. Was checking out that last freewing 90mm Yak too. But somebody got it.

[Hardway]

Awesome!

[Skyboom]

Love this plane. Just bought last scratch and dent. Woot woot

[Hardway]

255, Welcome to the Squawk and congrats! Nice bird! Jerry

[loki255]

LK255, I like it. Well done. Best, LB

Thanks LB!!!

[QUOTE=Hugh Wiedman;n212878]

I did have an issue with the left flap after landing it would not go up; but after unplugging and re-plugging the batteries it will go back up????

loki255:

Had the same problem with my flaps on both the Olive and Silver. Sometimes the left, sometimes the right. xviper suggested to me that sometimes these flap servos do not like the delay, so I took out the delay some 30 flights ago and never a problem again. There's some much outstanding knowledge with all these "squawkers" that you just have to sit back and follow their advice for trouble free flying.

Love this plane as well, over the winter when you work on the repaint, you may want to also add the sound system with the multi-engine card-adds a real nice touch.

I finished the preliminary assembly of the silver Liberator. Again very pleased with this girl and a welcome addition to the hangar.

I finished the preliminary assembly of the silver Liberator, my faithful assistant Freya was also pictured taking her hour long mandated nap.
The Lib had the yellow rudders so I primed them with white and black latex before a coat of Krylon rattle can aluminum and blue.
I taped on some of the the nose and canopy for the maiden as she will be getting an overall paint job and detailing this winter.
Got a picture of the plane after the maiden, sorry it's dark as it was dusk and the sun had ducked behind the trees and light was going pretty quick.
I CGed her with two 3S 5000s but found her to be a bit tail heavy so I put in some 4S 3300 which moved the CG forward a bit, but she was still a skoch, a scientific term(?), tail heavy. I flew her with the 4S 3300s and found she was pretty fast and leapt off the runway after a very short run. She was very tame on the flight, 3 minutes, and it was without incident and landed finding the batteries were down with 78% still remaining.
Second flight with fresh batteries was also uneventful with 6 minutes dialed into the timer and landed with mixed throttle at 67% remaining in each battery.
She settles in really well on final to touchdown, I really like this plane. With the 4S she took off in shorter distance than my F-86, and I'm pretty sure she will outrun her escorts...
I did have an issue with the left flap after landing it would not go up; but after unplugging and re-plugging the batteries it will go back up????
I did upgrade the struts but the props are stock. I'll put a little nose weight in and try to fly her next week with the 3S batteries.
Again very pleased with this girl and a welcome addition to the hangar.

New to hobby squawk but we absolutely love our B-24 I actually can’t believe this was brought out in foam. The B-24 is one of the finest models ever available from motionrc and flys as good as she looks. It’s a show stopper every time I take it out and I absolutely love honoring my grandfathers memory every time she flys
