Official FlightLine 1600mm B-25J Mitchell PNP Thread

[MikeT]

you guys need to read with a little more comprehension. I pay off my credit card every month, so I don't have to pay interest charges. You missed the point all together, that If I were to charge Motion RC the same rate as credit card interest for having my money for two months, they would owe me +/- $100.00. I hope you understand that. I don't normally allow people to charge my credit card and not deliver the product for two months. I understand this is out of the control of Motion RC; however, the situation could be remedied if your payment method was debited upon shipment, not upon order. Simple fix. Hope you guys that commented on my previous now understand and I hope the government gets their act together and releases this shipment.
By the way Evan D, 20% interest would be about $100.00. I don't understand how you get 114%.

Now you claim to pay if off every month , so what's your beef? You knew that they would charge your CC when you hit the buy button. You had a choice and you made it. End of story.

i think you’ve nailed it as is

Upon further review, and some shifting of the nose wheel axle, i think 7mm exposed axle is same amount for kit and scale front wheel. grub screw marked the axle just at edge of flat spot.

also noticed the 4 post on the wheel spokes are where they affixed the nose wheel mud/dust cover

I’m waiting for spare tires to be available from motion before i remove the ones from the kit wheels i have.

Not knowing their purpose, I left those posts off the front rim. But since you took the effort to educate me, I'll see if they can be arranged cosmetically

Printed in Polymaker ASA and Bambu ASA with same slicer settings. Quality is comparable, but the Bambu required glue stick to remain adhered to the plate.

Thingiverse has been updated with this version.

Thanks for the feedback.

I typically chase precision holes in 3D parts with a drill. For the front the sequence was 3.9, 4.0 and 4.1mm. Used the axle from my Vulcan to test this setup. Small steps minimizes the tendency to drift in a non fixtured setup. Freezing the bits gives me the impression they cut better rather than smearing the polymer.

I think I can trim up the width on the front axle about 0.75mm per side and still get the cap to work. Do you think that 1mm on the inner hub won't cause the tire to rub on the gear strut? It will be nearly aligned with the rim OD and the tires are wider.

On the filament - I recently got a roll of Bambu ASA and the jury is still out on it. Have had several 1st layer and spaghetti failures using it, including these rims! More issues than I have had with any other filament. I think the Polymaker ASA and Bambu Generic ASA settings provides a better result overall. Hopefully Bambu will evolve their slicer settings and/or filament composition to improve it's performance.

After I can complete a check print for the front mods, I will update the .STL files with a reduced width.

i printed with ASA from Bamboo Labs. Parts printed excellent

i think i might have measured the axle diameter a little off, or either the ASA filament shrunk. Most Likely the measurement was off a millimeter on the front and main axle size

mains width at axle fits perfect with the factory supplied spacer.

nose wheel width at axle is tight. Maybe a millimeter on each face of the wheel removed where the axle head and strut side meet.

i also noticed the factory B-25 wheel has brass bushings inserted.

I have taken these wheels as far as I can without the plane. If someone wants to give them a try, I just posted the .STL files.

https://www.thingiverse.com/thing:6184138

Planning to wait until the designs are validated to the plane before sharing on RCG. Special release for the folks here who helped me with them.

APR… $100 for a year is 20% but for two months you need to multiply by 6. you miss the point of my jest.

[Evan D]

You should get a better rate on your card. Considering you don't pay interest for the first month but still did for two months since you said over 2, you are paying 114% apr.

I understand the problem you are having. This is probably the most dysfunctional government in my lifetime (and that spans more than a few decades). Perhaps you might rethink the charging a customer full price on their credit card at the time of order and charge them instead at the time of shipping. Motion RC has had my money for over two months. If I were to charge credit card interest rates to MotionRC, they would now owe me +\- $100.00.

Pre Orders are what they are. If you pay your CC bill off every month you would avoid those interest charges. This isn't Motion's problem.

Tom, any updates on the inspection schedule? I know that yesterday was a holiday which probably means the inspectors are going to ease into their work today.

[desertdrifter7]

P2vguy. I couldn't have said it better myself.

[p2vguy]

Update - As of this evening, we are now 12th in line to be inspected.

Unfortunately, the wait is MUCH longer than expected 🤨. At this point there is a possibility the 3rd shipment of B-25 may arrive before the first. It looks like the total transit time is going to end up about 3 months by the time this container arrives. Normal is 4-5 weeks right now.

The government spends a month inspecting a container of model planes while they let anyone or any thing come in across our southern border without any inspection.

Is there any info/tutorials on the random servo movement generator ...

This would be easily accomplished on any of the Open Source radios which include a scripting language, e.g. any FrSky Taranis running OpenTX or RadioMaster running EdgeTX, both of which include a built-in Lua scripting interpreter. Lua's standard math library includes the math.random() method that would allow for all sorts of random motions to be easily generated. Just write a Model Mixer Script and assign it to the turret channel and one of the radio switches. Since the code is running on the transmitter, there would be no need to add anything special to the aircraft.

I wouldn't be surprised if someone hasn't already done this.

[Elbee]

Is there any info/tutorials on the random servo movement generator (30 years in the hobby and I've never heard of one). Someday I hope to receive mine and do this mod.

EM, Welcome aboard "The Squawk" Sir.

The RC Geek (Chris Wolfe) sells a version and might be the originator of the design.

I presume one could accomplish something similar using an Arduino/Arduino Clone and some simple 'sketch' code tinkering.

I do not know whether the RC Geek's is a series of lines of code or something more intuitive.

Best, LB

[Elbee]

I have taken these wheels as far as I can...

FnL, Thanks again for your great design work.

Clever use of the "hex" as a key. Width easily modded to adjust to Robart tires.

Alignment hash line, axle cover, well thought out and executed, Sir.

Printed the NG wheel.

Stats: 0.75mm layer height, 0.4mm nozzle, HatchBox Silver PLA, Prusa 2.6.1rc Slicer, "Snug Supports," Mk3S, Satin Build Sheet.

Evan D, I zipped over and voted. Great idea, Sir. Best, LB

[Evan D]

Not to argue LB but I created a poll asking which scheme people like best.

I took some photos of the B25 wheels...

TMD, great reference photos. I thank you, Sir.

MANFRED-Nicely Done. I think that livery is the best of the 3 provided.

Best, LB
