Official FlightLine 1600mm B-25J Mitchell PNP Thread

[Jdcrow]

Is there a "Special Callibration" process for the ESCs? I cant get them to go into calibration mode. Just keep getting the constant beeping that indicates throttle is above no throttle position.

i have throttle function on both banks. Just dont feel like im getting full throttle. Waived off the maiden attempts yesterday as it didnt feel like the aircraft was rolling out with any speed on take off.

This is the First Freewing or Flightline model Ive had it not work. including B-24, F-14, Me262.

Fortunately for me, it's not me in the video! I don't speak French, but I'd probably give it a good try if this was mine! Merde!

Never watch the parachutes,,,,, fly the airplane.

I think I am following. You want to add the 2nd row of exhaust ducts which are forward and circumstantially offset from the ones on the FL model?
Certainly this could be solved.

Challenges
1) Modeling the duct. I haven't modeled this type of geometry before, so would need to invest some time in learning.
2) Matching the existing ducts. I would likely cover or remove the existing ones to get the set to look same & scale.
3) Attachment to the nacelle. Would be helpful to see what is behind this exposed surface to create the attachment features for the duct.
4) Design for print-ability. Depends on 1 to 3.

If I had the B-25 model in hand so I could get all the needed data, estimate I would take 15 to 30 hours to develop this duct (eg design, print trials & initial installation).

There may be others who can knock this out more quickly - please be my guest!



The modeling challenge is very similar to the gunship nose so I will start exploring with that challenge in the next 2 or 3 weeks.

It's moving along more quickly than I expected. Not quite minimum viable product but a decent 1st draft.

If someone wants to share the HxWxL for the ones on the model, I could refine it. My guess was 4.4x6.8x13mm

Also interested in the nacelle diameter for the curvature of the duct mounting surface. My guess is 70mm...


The .STL file is available on Thingiverse

Quick update - As of yesterday evening (Friday Sept 8th) the B-25 shipment was second in line to be inspected. We expect the customs inspection to take place next week and expect to receive the container the week after. If I had to guess, I would say the container will arrive 10-12 days……

Again, I apologize for the SUPER SLOW delivery.

No apology required, Tom. NOT the fault of MRC in any way.

We do really appreciate the timely updates on the situation. I have never seen a vendor do a better job in keeping the customers updated on a delivery delay.

Whoa, just saw this. So sorry, Sir. Hope you rebuild. Best, LB

While we are all (patiently?) waiting here's a little video to pass some time with a reminder to always fly the plane. Low altitude tip stalls are a bummer! (see 16:00 of maiden)

I wonder if the FlightLine designers decided to drop the 2nd row of exhaust ducts in the service of streamlined looks v accuracy. I'll probably not do this mod.

FYI, The cowling exhausts and prop blade proximity to the cockpit windows caused B-25 pilots and co-pilots to lose hearing. Pilots left ear hearing deficit; co-pilots right ear. True!

Truth. I once (and only once) removed my headset while flying C-GCWM Hot Gen!

I thought my head would explode.

Thanks for the update, Tom.

The SQUADRON/SIGNAL Publications are a great resource for us Scale Nerds. Especially the Walk Around Series. Lots of good information. For example the B25 Walkaround shows lots of pics of the Exhaust Stacks, and also notes many times they were modified or had those covers removed for ease of servicing when stacks broke loose. Many can still be found. and on Amazon I picked up one as soon as i preordered the aircraft. B-25 Mitchell - Walk Around No. 12: Lou Drendel, Don Greer: 9780897473798: Amazon.com: Books

Tom,, thank you for the update and thank you for updating the product page. It is a terrible position to be in. We eventually will get ur planes.

[Fast N Light]

The exhaust routing for the engines was changed for the B-25 with the C/D versions.
instead of exiting out the rear of the engine cowlings with multiple cylinders collecting together. The individual exhausts from then on were routed thru the sides of the cowlings making a marked change in the appearance of the cowlings.

I definitely think a 3D printing would be a much better solution.

See!.
who else would give us updates on a weekend!.
That's why I buy from MRC.👍

We expect the customs inspection to take place next week and expect to receive the container the week after. If I had to guess, I would say the container will arrive 10-12 days from now but this is purely an educated guess. I've never had any inspection take this long nor have I had two inspections on the same container so we're in uncharted territory here. It looks like there is finally light at the end of the tunnel. I wish there was someone to complain to about the time this whole process is taking. Again, I apologize for the SUPER SLOW delivery.

Flightline has done an incredible job of recreating the B-25 J version. So I am happy that the only outline discrepancy other than the wheel rims is the number of exhaust stacks that are visible. And those appear to be a fairly easy fix.
somebody with FAST N LIGHT's skills will knock the design out before breakfast.
The only idea I came up with was to cut apart some old BIC pen caps and glue them around the cowling until I realized the plastic they are made of won't hold paint. My olive drab plane would look silly with blue and black lumps around the cowlings.
I definitely think a 3D printing would be a much better solution.

And the site does say late September.

"We currently expect the B-25 shipment to arrive at Motion RC in late September. We are extremely sorry for the delay and embarrassed to keep pushing the arrival date back. Any changes to the ETA will be posted on this page."

[MikeT]

Wow, you guys are some sensitive people. Didn't think my comment was that out of line. Now the question is, how long is a reasonable wait time? I understand this is through no fault of Motion RC, but sometimes you don't need to play the blame game, you just need results, no matter whose fault it is. I have been more than pleased with Motion RC and their customer service, and I'd venture to say that I've spent more money than most of you at Motion RC over the last 4 months. I simply disagree with the policy of charging people for a product and not shipping for over two months. This is not going to be the last airplane I order from Motion RC, but it will be the last airplane that I preorder.
And for those of you that are still confused about my credit card comment, let me clear this up by saying I never have to pay interest on my credit card because I do pay off whatever balance I have monthly. No, I'm not out of pocket interest on this preordered B-25. Just out of pocket for the cost of the model....for two months now. Trust me, this will not cause me to miss a meal. So, to the few of you guys that were offended, take a deep breath and relax, this too shall pass. It is truly amazing how ugly some people can get when hiding behind a computer screen.

Not at all. Just tired of people complaining about delivery times on a situation that they had no control over. Cancel your order and move on.

I agree all the vendors could do better in the notification/ information department too.

Pettiness, who spent more in a month or who joined before whom...

I don't think this is infighting, it's a discussion forum and we are discussing. But, yes I agree with you.
