Thanks everyone for the great comments. So far, the TREX 600 Aluminum Bottom Bracket has been a great success - preorders have been coming in and I'm looking forward to seeing these on flyer's birds at upcoming FunFlys over the summer. The first production run is a quantity of 100 clear-anodized frames and they are selling through very well, so if you need a frame get it ordered soon so you don't missed out. I'm hoping to start another production run towards the end of the month, which will be available end of June at the earliest.

The positive comments have been great on HeliFreak!:) I had sent the one prototype (no anodize, first off the CNC machine) I had on hand to my first customer who needed one ASAP for a personal project and here were his comments:

"It really help stiffen my Frame.. and feels alot more solid then with the Stock lower frame (little or no flex). I am really happy with the part and the workmanship is out of this world."

These types of comments are great encouragement and I'm also open to negative feedback (hopefully constructive criticism ;)) as well to continually make improvements for future projects.

I received the bottom bracket and its beautiful.

From a structural standpoint, I would like to make a suggestion. Align used 4 locating tabs and the 4 landing gear supports as locating tabs as well as six screws (14 points total to distribute the stresses transmitted by the landing gear to the frame). By eliminating the 4 locating tabs and with the large clearances of the 4 landing gear supports in your bottom plate design, all of the stress is now placed on the six bottom screws alone, with just the tiny cross-section of the screws to take the downforce of any mishap. If you could machine the next run with the 4 tabs intact and tighten the clearances around the landing gear supports, it would be perfect.

Hey Blueviewlaguna,

This is a great design consideration and I'll look into incorporating that into future designs. With the aluminum taking the majority of the shock in a crash, I don't know if the 4 locating tabs are necessary (they are needed for the plastic frame, as the plastic would quickly crack around the screws and flex), but it's worth looking into to. Just as a reference, I've put my 600 in hard numerous times and I've never had to replace a frame, as the carbon is surprisingly strong around the screw mounts, but it's worth possibly incorporating the 4 tabs for even more strength. Thanks for the critique, I enjoy hearing both positive and negative critiques as it helps me make better designs for the future.

Apart from this, do you like the design? Any chance you could post an image of your TREX 600 when it's installed? I'd love to see the design incorporated into other HeliFreaks helis.

Thanks,
Patrick

So, these are shipping now, huh?

That would be great timing, as I just planted my 600 into Mother Earth this morning and need to start the rebuild.

Yes, all preorders were shipped last Wednesday (5/28) and I have the remaining production in stock for same day/next day shipping (depending on time of order) via USPS Priority Domestic Mail. Sorry to hear about your 600 crash, but I can offer you the 30% discount for a frame as you donated to my 500 fire and I want to return the favor. If you're interested, simply send PayPal payment to sales@kdedirect.com for $62.97 and I'll get it shipped out to you ASAP for free (via USPS Priority Domestic Mail).

Hi Patrick,

A+ on the rest of the design, I especially like how the center section has been opened up to save weight since the aluminum is so stiff that just making a copy of the Align design in that area would have just added extra weight - only an extra 30 grams is impressive.

I am building a 1912H/1Y 10S (3700 mah) 600 and plan to use this plate.

This part works Great for what we are testing here.. here are a few pic's I have to post some better pic's later .( had to cover the name of my clients on the tail boom ) we are using Heli Freak Xtreme Frame from Rotoerworkz . so far this combo works really good.. will up date when we get more flight testing going..
kdedirect.com (sales@kdedirect.com) lower frame part so far is a really nice part and the work man ship is out of this world. we will be using more of his parts as we move forward with our project here..


now just wish I could find a Alum Forward Tail boom case ( boom attachment and where the Drive gear is ) to replace that stock plastic part.. its a week point to me .. here are a few pics ..

Don't worry T45, I'm already working on it and have a few ideas in mind. With Aluminum or Magnesium, I think it's possible to make it MUCH stronger and possible lighter than the stock Plastic boom case on all Align helicopters. My goal is to figure out a way to be able to change the tail gear set without having to remove the tail boom base - that would be awesome! I hate all the steps and screws needed to replace the tail gear set and/or belt in the current design.

Yeah i been thinking about how it can be done my self.. I would love to do away with the Self taping screws for sure.. and use 3mm screw.. I have a few ideas just have to put them on paper and work it out..

we are heading out to the Trade show this week and will be flying our UAV's with the lower frame parts. wish us luck..

Great News! The TREX 500 Aluminum Bottom Bracket design is almost out of production and will be shipping on July 2, 2008. The design is available for preorder on my website, so check it out (www.kdedirect.com (http://www.kdedirect.com/)). It is a direct retrofit for the flimsy, stock plastic frame and the quality is again the best available for HeliFreaks. I've attached a few images of the new design (the images are of a first prototype part from the CNC mill and have not been finished or anodized, Final production parts have a much cleaner finish and a clear anodize).

Just received my 600e bottom bracket and I must say it's a class piece of work! Pricey, but definitly seems worth it. This will definitely stiffen the bottom end of the chassis.

Kegerator, Great product, Just got mine and boy is it sweeeeeeeet.
I will try to post some pix up but looks like you got enough, I will do some light crash for ya to show how it turns out, I'm not going to crash purposily but with my flying style its going to happen soooooooooon. this weekend I'm busy with wedding and prep for funfly but next weekend I will do some damage to it and we'll see :)
Great looking tho~~~

I'm pleased to announce the new TREX 500 Aluminum Bottom Bracket Upgrade is available for immediate shipping and a third vendor (www.readyheli.com (http://www.readyheli.com/)) is now carrying the KDE Direct line:thumbup:. The new design came out awesome, with a satin-brushed Aluminum finish and a MIL-spec clear anodize to show off the CNC machining. I'm confident the new design is one of the best upgrades available on the market and I'm looking forward to the response and seeing them on HeliFreak's heli's at the Fun Flys! http://www.helifreak.com/images/smilies/nodding%20grin.gif

I lost my 10S in the sun and augered into the ground HARD - attached is a photo of the KDE bottom bracket that saved my frames and even the 10S brick.

It looks like it too the hit very well....I've been watching this post, quite honestly the rigidity of the bottom plate makes me nervous....

In a nose in collision like yours, all the weight is carried by the frame, which is mounted by -3- screws on either side of the bottom mount. I noticed in your picture how warped the bottom plate was, No big deal, if it were plastic it would be in several pieces. My question is how did the frame survive where the screws went through the frame into the alum. plate ? It had to either had broken the screw out or ripped through the CF right ?

I really really like the looks of this bottom plate, just worried about the effects on the frame....

Thanks,
Mark

No Damage whatsoever to the CF frame or the screw holes - all of the screws were still tight and in-place. When I unscrewed them, the CF frame sprung back into its original shape. The CNC plate did not allow the frame halves to flex excessively, compared to the plastic which would have just cracked and let each frame side move (and break) independently. Keep in mind though, that I have the Custom Heli 2mm frame which is very strong and does not have the cutouts that some of the earlier Align CF frames had. I am also using the Aluminum bearing blocks which will provide more resistance to frame shearing forces than the plastic ones.

The later versions of this plate have the 2 square locating pins on each side to help the 3 screws on each side with the sliding forces.

I am building 2 T Rex 600s and I ordered all the KDE upgaded frame parts and tail upgrades. Love the high quallity of these parts. They will hopefully protect my V Bar and other electronics
Thanks Ken

Just installed my bottom braket for the 600, love the rigidity that has been added to the over all frame. Think that i'm going to finish off with rest of the 600 to stiffen the frame further.

Certianly wish that i had the bottom plate when I had crash and my Hyperion $240 pack decided to explode after the plastic plate failed to do it's job.

Thanks KDE for the great service.
