Official Dynam 1500mm B-26 Marauder Thread

I left the tail weights in my B26 it balances out quite nicely with an Admiral 3600 4s. I just ordered some graphics from Callie as I doing a repaint on my plane.

I can't stand extra dead weight. So I removed the tail weights, and carved out the back of the battery compartment which opens up into what would be the bomb bay. So when I put my 4000mah 4s in there in sits touching the what would be the inside of the bomb bay doors. This moves the CG back far enough so that I don't need the tail weights.

I completed a repaint on my B26 this past week. Before and after pics.

Nice Bro!!! Glad you have hung in there and what a great job!!! Blessings! Jerry

Looks great!

I really hate the silver paint scheme. This looks much better. Anyone have ideas to secure the engine cowls? Such a dumb design idea mounting them with magnets. They are bound to fly off into the props.

Glue them or secure with screws.

Thoughts?

I spot glued them with FoamTac. A small dab of FT between the magnet points is enough. When you need to remove the cowl again, just slip a razor where you put the glue and it should free them up.

Thanks. As long as engines hold, shouldn't need to take them off.

My other complaint is the mess of wires in the battery hatch. Mine has servo wires and receiver rerouted to top under wing hatch. Much neater and easier.

After a few changes to the servos and the installation of a gyro, it now flies perfect.

After mine became a hanger queen for about 3 years I took her down off the ceiling and flew her again and realized that she is still the underpowered bird I remember. So I finally upgraded the motors to 3536 850kv and she is a new girl. Plenty of pep and flies around at just under 1/2 throttle. I now have taken her all apart for more detail upgrades. Bombardier compartment upgrade and upper turret in Leroy's 3d print.

I haven't done so, but she does need a power upgrade, I modified the leading edge of her wings and added wing fences on the outer one 3rd, so that she wouldn't be a tip stalling viper anymore. Having said that, what's preventing me from adding more powerful motors has been not wanting to move the CG any further forward. I removed the tail weights and dug the battery compartment out to compensate. How much additional weight did your power upgrade add?

[quitcherbitchen]

Almost nothing. I moved most of the servos one bay back and made a bomb bay. I fly with a 3300 4s battery and get 5.5 minutes. The new motors weigh double the old Dynam, but it didn't seem to effect the CG. I removed the tail weights long before I even flew it.

Awesome thanks I fly her on a 4000mah 4s, but I always move the CG aft of the Manufacturers recommendations. The tail of my 4000mah now sits in the bomb bay floor.

I use to get 8.5 minutes with the stock motors. I think if you lighten up the plane by moving the servos aft and dumping the extra weight you could fly the stock plane on 2200 4S. I was tempted to go that route before modding the motors. Now she flies with much more authority and so far(only 4 flights with the new motors) she hasn't shown any over roll tendencies, but if you yank the elevator and haven't dialed down the throws she will still snap. I raised the tail about 5mm and changed the incidence at the rear of the horizontal by 7mm. Not just shimming the back of the horizontal only but lifting the whole thing up. The real B-26 the tail sits on top of the fuselage almost flush. This model they sunk it down. I thought maybe the elevator is in some bad position to cause it to snap. I have learned not to jam the elevator around and be careful. Neutral centered elevator now.

Which servos are you referring to? I don't have any servos forward of the wings.

[quitcherbitchen]

The servos in the bomb bay. I moved them back to the next bay. Here is my turret I made from the 3 d Stl on grabcad. I made the blast shields.

Ah tracking...a little minor surgery.

[quitcherbitchen]

More like MAJOR LOL. Actually, I think it is all going to be worth it if you love B-26s. If I had to build the Windrider models version it would come out way heavier and probably fly worse. I want to find a way to get rid of the heavy dynam prop hubs too. I would rather add details with that weight.

Picked up the book by William Wolfe B-26 Marauder the ultimate look. This is a massive 3 inch plus thick book about the Marauder. Pictures I couldn't find on the internet and descriptions and history that can only be appreciated by B-26 fans. It weighs 8lbs.
