Official Dynam 1500mm B-26 Marauder Thread

I have the same livery as well.

I finally got the chance to maiden mine this morning , No Issues at all . Used a 3600 set at the top of the battery ramp, because any higher and it will hit the canopy, thru a 1/2 of weight in the front and away she went . Added some up trim and flew great . Not sure why I read through post and people were adding shim to the tail because it doesn't need it . If you need up just adjust your trim . All those other things do nothing but confuse someone who may consider this plane and think they may get a dud .

Too much over thinking , put a battery in and fly !!!!!!!

Maybe they finally corrected the issue at the factory

Cool! Too bad we're not close enough to fly formation!


And Hippie, glad to hear it went well. That's reassuring.

Glad to hear you finally got a chance to fly it Bryan, I went to a fly in yesterday and got a little stick time in myself. Had a good time with some good folks. I did buy a used ST Model Acrobat for some 3d action. I got it at good price. It was a little windy but still got some time in and had a good time. Glad to hear the maiden went good.

I heavily doubt that. I put 3mm in mine and don't think it is enough. 4mm would have been better.

Luck of the draw thing then.

I don't think so I have had this one since before December just sitting around . I didn't even do the CG on it til five minutes before walking out the door .

Just a basic maiden nothing special . But I will say I feel like too much hype was put into the trying to shim the tail and do other things to take the need to trim out. I have many planes that have a natural flight that needs trim all the time . As long as the CG is done RIGHT it will fly fine. I have a CG Machine by Great Planes and never used it only looked at Mike & Ryan's video and used what he did ...... Work perfect .

Thanks Pauly and Nodirt

Just set the CG and fly !!! I can feel it may want to keep up some speed and not go too slow in the turns or on landing . It floated in like it was on a cloud and yes the flaps were down full . Take off was half flap because I was on grass . Watch the video that Mike & Ryan did , set your CG there , add a little weight in the nose if needed and go . You'll fine . Enjoy

Sure you can go fly it, but if it needs a 1/4" of up trim to fly level then the incidence is way off like everyone else. You could fly it like that all day, but it isn't really correct. The tail shim is to correct the incidence angle and it takes all of 10 minutes to do.

On another note, I did a few bomb runs Saturday and the bomb bay door servos were interfering with two of my four bombs. I needed to move them in more to get out of the way of the bombs. Two bombs wouldn't deploy and would hang or explode as they left the plane. Looked pretty cool when it did explode. Looked like flak. I'll post a video later.

Here is the video of my first bombing mission with the Marauder. Sorry for the lack of quality. My buddy has an old phone. One of the bombs predetonated leaving the plane, but looks really cool like flak. Missed the targets completely as there was a mild cross wind and they went wide by a lot. Plane lumbered into the air with 4 fully loaded Adam Bombs. Full military power and half flaps.Cruises at about 55% throttle. I use a lighter 3300 mah Glacier 4 s battery since the servos were moved rearward. Still get a solid 7:30 of flight time. Larger nose wheel helps take off considerably more then the one I had on before. Helps the AOA. No more leaping into the air. Dialed down my elevator travel limit to 70% Vs 75%. Lands perfect now. No wing rock like the first two flights on landing flair out. I was tempted to cut some washout into the tips, but I don't think I need to so far.

Finally got to maiden the Marauder!
It flew pretty well except for one thing, even with the 3mm shim it nosed down. I maxed out my trim even after moving the battery back three times.

I found when I pulled up elevator it would re-center a few degrees down. Pushing down it would center correctly. I'm going to replace the servo.

Other than that it flew great. I only went up twice so there's more tweaking to be done. I think it will be a nice addition to the fleet. Thanks for all the tips.

And I can't wait to load the bomb bay!

I found when I pulled up elevator it would re-center a few degrees down. Pushing down it would center correctly. I'm going to replace the servo.

This may not be a function of the servo but rather to do with a very sticky foam hinge. If memory serves me correctly all the hinges on this plane are foam all the way across (except for the flaps). All such foam hinges must be manually "exercised" vigorously before permanently attaching the control rod. Did you do this?

[rifleman_btx]

Was gonna ask that too. Those foam hinges can be serious pests

[NoDirt!]

I had previously flexed the hinges but thanks for the tip guys.
It was the servo. I disconnected the pushed from the servo and I could see the arm not centering.
I've replaced it and it looks good to go. And of course it looks like it's going to rain tomorrow :Angry:

[rifleman_btx]

Awe man! Let's pray for good weather so you have a chance to try it out tomorrow.

My second B-26 is now pretty much done. The prop tips have been painted yellow after these pics were taken. She is now ready to join her squadron mates from the 344th Bomb Group in missions at Apollo Field. She does have some mods from the stock plane - motors, ESCs, and landing gear.

I got to test mine today after having some issues the last time I flew her. Today after doing some overhauling she flew like a dream.

[NoDirt!]

BTL, it looks good. What prop spinners did you use?

Rifleman, I'm glad to hear of another successful flight!

Thanks NoDirt! The spinners and hubs are from the 980mm P-47. They fit perfect on the stock props.
