Official Dynam 1500mm B-26 Marauder Thread

To me that would be the next best option.

You might want to take a look at the retracts from the Durafly line at HobbyKing. They seem to be the same design but not the same control board. I took one of the retracts from an old Vampire and transplanted the mounting plate from the stock B26 nose retract and then the whole strut assembly over and it all worked. The holes for the mounting plate is the same. Unfortunately, the Vampire part is not in stock and you have to buy all 3 but if you're looking for a complete replacement, this might not be a bad way to go. You can also look at other Durafly plane parts and see if you can buy just a single retract.

Which Freewing? My nose gear only works every third try. Are they direct drop in?

Wag727 used E-flite 15-20's and it sounded like they fit without too much trouble. Probably not the cheapest way to go but if they're not a lot of fuss...
I've been hoping he would post how they worked out and maybe a photo of the nose gear.

I will check these out as I am getting aggravated with the stock retracts. I just don't understand why the Dynam retracts are sensitive to cooler temps. I'm thinking that maybe the grease that is used on the gears in the retract is possibly too thick it might be stalling the gear train and maybe fouling the limit switch. I might open one of the retracts to see if that might be the problem. I just checked out these Durafly retracts and they are out of stock right now.

[quitcherbitchen]

I just think the Dynam boards are a bit of substandard engineering. Must have been a patent they had to work around --Though I heavily doubt it--in order to make them so wonky with the whole 8 second delay and temp sensitive.

So I got my Maruader today and overall I'm stoked to have a new plane. It did have some shipping rash but nothing too major. What erks the hell out of me are the sloppy glued on engine nacelles gapped seams and just misfitting. They dont even lay flush with the wing requiring sanding and gap fill. Even the magnets on the cockpit hatch and top wing cover are not flush causing gaps. Looks like I got a project plane needing some adjustments, cutting, gap fill, sanding and painting to do.

It's just said to spend good money and have issues like this

Check this thread earlier on, when we first received these models everyone posted about the fixes that were needed. Around post 385 for me. There are definitely several things you'll need to check. Flap hinges, wing mounting pads, magnet placement, loose guns, stab shim, tail weights, balance point, elevator control throw etc. Not to mention the racecar wheels and WWI pilots!! But once you've sorted out these issues it is a really nice-flying plane. I really enjoy mine a lot.

We are hoping that Dynam will fix some (or most) of these issues when they bring out the P61 (uses the same motors, props, and landing gear). Motion is working on that.

Jing Li on the RC Groups was bragging about their commitment quality

[rifleman_btx]

Would that be second to last?

[TiredIronGRB]

Would that be second to last?

"Last to none"

[rifleman_btx]

Yes!

[handyman220]

"Last to none"

How can they comment on QC without having an understanding of the whole concept! ;)

[quitcherbitchen]

By talking out of the side of their mouths. They know how much money they save using inferior components and labor. They think if they talk a good game that people might buy it. Well we put up with it, but not anymore. I think Motion is right. They should improve their products before Motion places an order.

[rifleman_btx]

To me, every since I've been dealing with Motion and stuff I bought from them, I feel like they've been a game changer in the industry. In service and demand for quality. Hands down the best I've ever seen.

[xviper]

One has to keep some things in perspective here. Consider that this B-26 costs $249.00US. If we demand and expect higher quality that would make it comparable to stuff from Freewing/Flightline and FMS, the price goes up. By comparison, take the FMS B-25 for example. It retails for $314.00. Now, take the Flightline P-38 Lightning and F7F-3 Tigercat as 2 other examples. Those go for $349.00. I consider the FMS plane to be of slightly lesser quality than the P-38 and F7F. If we had slightly higher expectations for the B-25, it would be priced in the Flightline plane territory. In the same token, if we have higher expectations for the Dynam product, it will be priced in the FMS territory. Higher yet, and we're in Flightline territory.
Personally, I've always liked Dynam for their price point and I am always aware of the limitations and lesser quality of that brand. That doesn't stop me from buying them. I am therefore, fully prepared to put in a bit more time and money to make them the way I want them. When I have those higher expectations, I buy FMS and Flightline. Be mindful of what you ask for and what you expect. You can't get steak for hamburger pricing.
I was very excited and grateful that MotionRC took on the Dynam line. The other choices for suppliers were much less than desirable and I stopped buying Dynam products. I, for one, hope that Motion doesn't stop buying from Dynam until they up their quality. Once that happens, there will be no more products at that price point to choose from (except maybe some of the much lower end HobbyKing products). Even those H.King planes have their market.

[rifleman_btx]

While that is true, what i expect is a product that will fly and land under my control out of the box. My first B26, while it flew for the most part, it decided to land nose first on its own on it's maiden venture to the field, with the specified 4000mah pack in it. After buying the new replacement parts, and doing all the prescribed modifications, it now flys like it should have from day one. I will add this is the ONLY dynam product that I had an issue with. And I have had 3 previous, to include the PBY, flew great, all the way to the scene of the crash many many flights later, and the f6f that's still flying perfectly, and the f4u flying perfect as well. So my complaint would be, don't be rushing out the new stuff before you know it's really ready to go.

Its a good point, there is definitely a niche in the market for less-expensive planes. I think that it's reasonable to expect that they shouldn't be defective, at least. I hope that Dynam can continue to provide planes in this category and they should be on a good track if they try to make efforts along the way to implement quality improvements without affecting the price point. Whether the Dynam line continues to be carried by MRC is another thing.... its sure not going to happen if Dynam isn't willing to play nice (re: the Bitgo affair). I hope these two companies can work something out.

[Saltydawg]

I understand that with higher quality comes a higher price. I would at least expect for things like magnetic clips to be flush on the battery access and center wing cover. And the engine nacelle to be aligned on both the onboard and outside edges. It's the obvious misgivings that drive me nuts. Overall it's a great model.

I'm in the process of removing my nacelle to realign them and open up ports for cooling

[quitcherbitchen]

You haven't tried the landing gear yet.

[quitcherbitchen]

On RC Groups I was a accused of being a conspiracy theorist for suggesting that Bitgo was an EB-5 Visa plan by the Dynam owner. Being married to a Chinese this is all a lot of them talk about. It's all legal. To me it makes perfect sense. Good news is once they get their Citizenship they abandon the business.
