No More Taco Mod - Battery Strongbox Complete - Batteries can be installed with canopy on
Original start thread for Version 2.0 https://rc.runryder.com/t686019p1/

For those that are interested, got the strongbox all finished for No More Taco Mod Version 2.1. Turned out quite nice for me, just hasn't been lightened yet.

The pieces on the bottom simply snap into the frame which hold the packs in both laterally and horizontally. To me, that was a real secret to the strongbox and I must say it was a epiphany moment when I thought of it. The straps then go around it and hold them vertically.

The velcro on the battery rail is just cushioning and not even needed at all. The velcro strap at the back of the box secures the batteries in and all I need to do is simply take the strap loose and the batteries slide out of the strongbox to be changed.

I have taken the strongbox out and put it back in without having to take off the canopy so that was pretty cool, I was pretty amazed at how easy it turned out to be. It will take quite a hard lump to even consider damaging the batteries, lol. The frame would be toast, but then again it probably would've been toast regardless. The CG is slightly forward but will be spot on once the strongbox is lightened.

Thanks for looking Now I get to have fun tomorrow with it.

Thank you goes out to Mikado for making such an awesome frame.

Dude I have been observing u tinker with that thing, now your just gonna squeeze the lipos in a crash. Just get some 1.5-2mm fiberglass and build a nice little box with room in it so the lips can detach itself slowly off the Velcro in the box between the lipo and box on impact( Velcro acts as absorbance slowing the kinetic energy), and if you really wanna build a dooms day box use some kevlar and foam, foam absorbing impact and kevlar for prevent penetration (uhhhh, ahuh, huhuhu, I said penetration!).
Great now someone is going to steel "funguys" idea and probably patent it, oh well better for the Hobby!

Nice clean Alu. box by the way.

This is not my first foray into the aluminum strongboxes and I have crash tested them before, not on purpose mind you, lol. Even with boxes that were only half as good as this, they with stood pretty hard hits and this was on helis with the battery out in the open in the front.

Not saying that its 100% bullet proof, but certainly better than the batteries just sitting there. I'm sure someone and everyone can come up with what ifs and critiques on this and anything else, but cie la vie.

Also, there is no cushioning needed and they need ventilation anyways especially here in the summer when its 120 degrees outside.

I stood on top of this box with my heel while holding a 45 lb weight for a total of 225 lbs localized and the box did not deform. They only look flimsy.

Also, I've found that I don't want to give too much space between the batteries and case because the batteries are pretty durable if they are supported well and if say a locallized hit happens on a flat portion of the box, the battery will disperse the force and the whole box will work to hold shape instead of just that localized area where the hit happened.

This is just for me, whether or not you like its thats cool, I know what this box is capable of and squeezing by my experience is far less a concern than frontal collisions to which this box is a champ. I have had plenty of Benjamins saved in the past by strongboxes so to me it hits home pretty good to protect my batteries.

Thank you for the compliment.

Nice box for sure, sweet logo also, can I borrow it? The box looks like it was built by a pro, in machine shop. My buddy crashed his heli and the frame cut into the main battery wires, maaan! it looked like arc welding going on on his heli.
I wonder what may happen to your wires?

How much weight does that add on? I'm actually surprised that no one markets a lipo box like this. Nice job BTW.fly til its dry

Wire protection is next just haven't gotten to it yet. In the past I have cut wires too in a crash they just didn't short thank goodness. I have used some velcro in the past that I have around the wires and it is very tough. You can see that velcro protecting the edges of the wire openings. With this, I will probably put that around each wire like I've done and then wrap it in a nylon fabric type tape for extra durability.

The weight is 195 grams in its non-lightened form which is not ideal for sure. Lightened I'm gonna say I will get it to about 110 grams if not less. I may go to a BEC or small lipo and which will save 60 grams over my current separate battery pack, so it will be a wash in weight.

I measured about 25-30 grams of frame weight removed. When I flew the other day I did a massive tail slide to nearly full pitch piro flip pull out and everything stayed together, so the frame works.

With the standard Logo set up stick pack, adding the protector plate, sliding tray and velcro on the batts and such it was already adding on about 40-50 grams right there, so its really not that big of a difference from zero protection.

PS: Sure you can borrow it, you're going to sleep soon right? I'll loan it to you in your dreams, lol.

I like the Idea. With the canopy on how do you connect the batts to the esc? Did you have to lengthen the esc wires? Whats the trick?
Your box also protect the pinion from eating the batts in a crash! Nice Job.

The wires are just long enough that I can snake them out with just a little bit of room and connect them to the batteries. I need to change out the deans, I've got the 6.5 castle connectors but I just don't feel like soldering right now, I should be asleep, lol.Still buyin' and flyin' then crashing and cryin'

Getting some more flight time with the No Taco Logo
Been getting some more flights on the modification. So far frames are holding up great for flight. Even zinging the head at 2200mah and doing large tail slides to piroflips have not been an issue for frame strength in that area. And this is to the frames holding up just fine having more than 130 grams extra to hold on the battery rails.

Simply loving the mod and simply loving the Logo. If you want to try this with your Logo I can say it is very worth doing, reliable and quick to change the batteries. If you have any questions shoot me a pm. Thanks
