Official Dynam 1500mm B-26 Marauder Thread

[CFIT rob]

MIB66 , if you havent already, make sure your cg is 65mm or less. Some are flying at 55mm ,60 mm,65mm. It seems that no one flying beyond 65mm(i'm 60mm and love the way it flys). The plane is a widowmaker if tail heavy. Also give it 2-3 mm up elevator(i gave mine 1mm and had to give it most of my available trim. I ended up at 3mm. Really sucks to have to madly click trim on a maiden. Go easy on the elevator on take off to keep it from leaping into the air. Full flaps and bring it under a little power and its very easy to land. If I come in to fast it has a tendency to bounce. Hope this helps.

That and you can run an 1/8" shim in the back of the tail so you won't have to use up the trim and the elevator flies more flat

Working on my B-26. The inner flaps on mine do not work. I plugged the outer ones directly into my receiver and they work. Unfortunately they used some kind of glue to keep all the y connections together and I cannot pin down the problem. Any suggestions on how to get the connectors apart without destroying them?

[rifleman_btx]

I ended up having to cut them out and replacing them on mine. Not a fan of the glue

In the final throws of moding my B-26. With help from one of the guys at Robin's Hobby in Glendale, CA, I was able to first replace the red/green landing lights with white ones. Added new larger nav. lights (not the ones in the L.L. area) and covers. The covers are a little to big to be plush with the top and bottom of the wing tip, so I'm flushing it at the top and let it overhang the bottom (will add a piece of blu cor to create a fairing. The wiring setup allows the L.L. to go out when the gear is retracted and on when extended. With the L.L.on after I taxi in, I can turn them off using the Aux. 2 switch leaving the navs. on. If anyone would like to see and know about the wiring setup, I'll attempt to describe it later.

The first pic shows the nav. and L.Ls on and gear extended. I can turn the L.L.s off and on with the Aux. 2 switch. Still trying to get it to happen automatically. The second has just the wiring needed to get the lights to work. Will post again as soon as I figure out the problem.

Mix aux 2 with gear after you reverse aux 2. Freewing retracts work opposite everyone else, hence their sequencer works opposite what your trying to do.

i had same setup except futaba.

Thanks, Ryan, will do. First job in the am. When it works, I try to shoot a short vid. In the meanwhile, here's one more pic calling out the various wiring.

Would not the front landing gear assembly of the FMS 1400 T28 work as a bomb bay door assembly?

[Brandon Moon]

I did exactly that very thing with that very same assembly on my 1450mm FMS B-25 and it works great!!!

[quitcherbitchen]

Bob has used those before. Too small. The ordinance barely fits through.

Adam is right. My first FMS B-25 had this as a bomb bay set-up. It really is too small - at least for my bombs of choice "Adam Bomb".

It is a video I shot showing the gear up and the landing light out and the gear extended and the landing light on

I will have to copy this, Brent.:)

[Bigrc2]

Good luck Bob. Hope the diagrams and vid helped. Any problems just let me know. One additional thing, you'll need to add a "y" to connect the nose gear retract to the mains.

Will do, Brent! I am still hoping to get down there on the 16th.

It would be great if you could. If the turnout is any where as good as the last event, it should be terrific!

Well after many more hours of extra work the JM-1 ( formerly B-26) is finally done. When the temps out here go down about 20 degrees I'll take it out and maiden it. I have never had so many things to correct on a foam plane before. Out of the box this plane was a nightmare with ill fitting panels, cowlings and hatches. Had to replace those drag slick tires, both rudder and elevator servos.
I should have trial fit the outer wing panels before paint. The right panel does not fit the center section flush. Its about a 1/16 of an inch off. The cover for the center wing was off a bunch and to correct the problem the front magnet was repositioned to get it flush.
I used mineral spirits and absorbent paper towels to take the paint off. I just wet the towel, wipe it on the surface and let it set about 30 seconds then go back over the area and wipe the paint off. It takes it down to white foam. After removing all the paint I wiped the area down with rubbing alcohol (70%). The cleaned surfaces were then primed with Fusion Colormaster white flat primer. Final color was Cadmium Yellow Light Hue in a spray can. Ordered from Dick Blicks Art supply.
Prior to the planes arrival I had already decided on the Marine JM-1 so I had Callie Graphics do up a set of decals for me. She is in process of doing up some Curtis Electric prop decals. The JM-1 was used as an airborne target tug.
Removed to fuselage gun blisters, top gun turret, rear guns, and the dome just behind the cockpit.
Taking down the raised ill fitting seams will leave some fuzzies. They can be removed with some real fine sandpaper.

Well after many more hours of extra work the JM-1 ( formerly B-26) is finally done.
Prior to the planes arrival I had already decided on the Marine JM-1. The only Marine version that I could find was formerly the Navy AT-23B then re-designated to U8 for the Marines

The JM-1 was used as an airborne target tug. Designated by the Navy as JM-1 to use as a tug

Looking forward to some pics :Cool:
Oh.......and welcome to the Squawk
In case you would like a Navy look. ;)

[Mike O.]

Thought about the JM-2 version but I can see the bloody plane better in yellow. I'm hoping that the quality of the P-61 Dynam is planning to release will be of a better quality than this B-26. I hate swearing at the project being built...................
