Official Dynam 1500mm B-26 Marauder Thread

They all have those nuts. Cheaper to add nuts than to re-engineer the mounting bracket. :Silly:

[Mad Baron]

Well I am going to cut out a spacer out of aluminum plate instead of these nuts.

If you're going to replace the stock retracts (highly recommended if you plan to fly in cool temps), you might want to dry fit the new ones before making the plate. They may fit differently and your plate may not be the same as what is needed for the stock retracts.

[Mad Baron]

I haven't planned on replacing the retracts for different ones I would have to find out what brand would work and depending on the price would determine weather or not to get them.

Maidened mine today with a full bomb load, but got a little distracted with the nose wheel not going up. What a great plane. This thing is going to be getting a lot of flight time now. Flew 7.17 minutes Dirty and Heavy on a Glacier 3300 4s battery. Definitely needs more run way then my B-17 without an flaps on take off and the runouts on landing are pretty long,but she is well behaved for the most part. I did almost blow the first landing by pulling the elevator too hard. She looked like she wanted to start a tip stall so I pushed the nose down to a one strut at a time landing. Second landing was a greaser.

Congratulations, Adam. I will be building my second B-26 tomorrow. I have new motors and new retracts planned. Did you drop any bombs?

[Alpha]

Congrats, Adam! You'll need to bring a larger foam village to Apollo now.

[NoDirt!]

Sounds like a good maiden flight. AND with a bomb load :Cool:

How many bombs on board? And if you dropped, did it affect the CG?
I just cut my bomb bay open and am working on the details.

[quitcherbitchen]

No I didn't release the 4 bombs on both flights using one battery. The nose wheel got hung on the plastic cover and I kind of got distracted looking at the plane as it flew around to see if the retract was indeed back in the down position or did I burn the motor on it. If flew around with the gear hung for a few circuits before I noticed it wasn't up. 7 minutes felt like nothing. I was playing with the flaps a bunch too. I don't think the bombs effect CG as they are basically on CG and as long as the plane is slightly nose heavy like mine was to begin with it should be fine. I used 60mm as my CG. @NoDirt. without making custom fiberglass doors there is no hope of fitting 4 bombs inside using the stock foam as doors. The most that would fit using the foam would be 2, but it would be easier to make. I highly recommend that everyone move their servos back one bay as I did. Access is super easy and it just makes sense for CG purposes. It was also really easy.

@ Alpha The foam village usually is good for no wind, but you didn't get to see the Hokaze Destroyer.

Adam, I will be building my second B-26 today and plan to move the servos back as you recommend.

I finally got up the nerve this weekend to break out the Xacto knife and start cutting the bomb bay (and I was sooo close to flying this thing!)
I'm going the single bay/two bomb route. I raised (lowered?) the tail servos to make some room and cut out some foam. I have a couple servos but no hinges so, not knowing which ones would work best I ordered these two gear door styles to try. If they work I'll let ya'll know.
And thanks to you "early modders" for the tips and photos.

Hello ND..........I was looking at those exact two different hinges on HK for my big Invader and Tigercat projects but of course couldn't find any dimensions.
Would you possibly snap a pic or two of them with a mm scaled rule next to them in L & W and PM them to me.
Thanx,

[NoDirt!]

PM on the way

[themudduck]

You may want to look at Sonic-Tronics, they have a bunch of hinges that look like this. I put a link to this page below.
One of these is spring-loaded which could be really handy. I'm going to order some...

[capecoral]

changed my TX/RX and cannot find my instructions can some one help with deflection most important to me is flapsi think low is 10 deg

[Hardway]

Go to Motion RC and on the B-26 page, go to the support tab and the manual is there to download.

[capecoral]

I went to that page BEFORE i posted .. it does not show any settings for flaps. so that is the one i really need from some one that has experiance.

[quitcherbitchen]

Thanks for the link themudduck. Just what I need for gear doors.

I am sorry! I forgot that the Dynam instructions are not really helpful... I have my TO Flaps at about 15 degrees...:Cool:

Time for a Marauder update

Here's mine finally. Almost ready. Just need props and final adjustments.

Not much info available but I like the livery.
No name. She flew with the 322nd bomber group, 450th bomb squadron. Flew at Normandy. One page said downed by AAA.
