Thanks for the replies - I now have all the information I need to get gear doors working

As for the grass then yes, it might be an issue, but I can take off using a concrete track if I need to and I can also mow a landing strip with really short grass (I did this in the summer this year and the others seemed to like it as well - used quite a bit of mower gas up though!).

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?

I'm not sure if the doors will clear a grass runway, it's pretty low already.

But regarding the door delay, it's built into the control board - see post 1381

Mikdys The cheaper stuff will be fine. I use cheap PLA that I find here in China. Just be mindful of ground clearance... I noticed in your avatar that you're flying your B-24 on grass.

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. :hugging:

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.
