where does the bat. go? I cant find anything in the build guide. any photos?

I put my battery below the power pod, or on top of the wing just behind it, that's were I thought it would go.
Don't have any pictures, as I've since crashed the plane

Here's a picture from the build guide, I put the battery were the red dot is. Hope this is helpful

thanks. That helps a lot.

@FlyerInStyle I'd push it as far forward as possible, pretty much right behind the powerpod worked for me to get the right CG.
@MooreRC thanks for the clarification!

thanks. got that set up. Just a note if you were ever to edit the build guide, please specify how to put the linkages in, as it was a nuisance. I modified that part and stuck them out on the outside. Also, is one skewer enough to secure the powerpod? just a little skeptical.

Thanks for the feedback, I'll keep that in mind!
I found that the piece under the pod, if glued in correctly, constrains the pod to 1 degree of freedom, which can be fixed by the skewer. I saw two ways in which the pod would come loose over time or due to crashes:
i) the piece below wears away
ii) the skewer hole widens.
But if the piece below is glued in well so the pod is tight, and a bracing (such as a piece cut from an old credit card) is glued over the skewer hole on the pod, the pod is not only well-seated but also resilient to crashes. I nose-dived my p51 when an esc smoked mid-air, the and pod had zero wiggle afterward. But again, that's contingent on strong assembly. Hope that helps!

thanks. Sadly after a couple crashes and a broken wing, it did wiggle a little. it should be fine though Also, just a note, I love the landing gear design, but fro some reason y 850 3s ouwld not fit in the battery slot, and it was hard to access. I solved the problem by adding weight to the front, and putting the battery below the hatch. just a note. thanks for the amazing design though!

I built the P-51, this was very straight forward and a blast to build. I did 3D print the exhaust and it turned out great. finding the correct COG was a small struggle with batteries I had but I got it figured out. It flies great and looks awesome. Its not the cleanest build but my next one should be much smoother as I learned an a lot on this. Thank you so much to MiniacRC

Looks great!

 

[synjin]

This is my build of this plane. It’s fun to fly!

 

[luvmy40]

Those both look fantastic. I'm going to have to build one of these. Someday.

Been a minute since I checked back on this thread, but I'm sure glad I did! Y'all are so talented!

@FlyerInStyle: Glad you found a workaround! I agree in retrospect. My first prototype was easy to balance, but the second one which I decorated more (thereby adding lots of weight aft of the desired CG) was impossible to balance without dead nose weight. Out of curiosity, which brand 3s 850 were you using? I just like to collect data on the dimensions of batteries people use, for purposes of future designs.

@banknyank: Thanks so much for giving this design a go, your build looks real sweet! Love the color choice and the 3d printed accessory. In retrospect, I also find the foamboard molding a bit difficult to pull off when building at this scale. Glad yours flies well!

@synjin: Holy smokes, that is an eye-popping build! Gotta show it to my buddies! Glad you're enjoying flying it!

This plane has long since been retired, but i would happilly build another one to test revisions (if you do end up changing it). I used zee 3s850 batts. I think that extending the nsoe on the mustang wont hurtit but it will improve balancing. Also, @MiniacRC , as a side note I really like your style of desigining planes, could We design a plane that I have wanted to make, the saab j21 together?

 

[MiniacRC]

This plane …

Thanks! Yes, that does sound like a needed mod for the p51b. If I ever have the energy to reboot the design, cg and thrust angle will have to be seriously considered!

I’ve never seen the Saab J21 before, and it looks to be a sick airframe! Would love to be part of the design process.
