Kake...upgrade!

Today the Cleveland area is getting hit with random storms, so I am going to attempt to update Kake's power system.

The $100 Turnigy 2300kv motor and ESC combo has served me well pushing Kake to 100+mph, but it is time for my original speed runner to reach maximum velocity.

I have (as seen in previous posts) a 1300kv Leopard Hobby 4090 motor and a Castle XL2 that are doing nothing at the moment. So its time to put them to work. In addition to the power system, I am going to be installing using the Futaba radio I picked for the DLS Projects as the range needed for this attempt will likely exceed that of the Tactic systems I have used so far.

On 6s, my goal is to break the 110mph mark and 125mph on 8s (if the motor will hold together)...

This is probably impossible, but I am always up for a challenge.

DIY simple aluminum battery trays

Flat bar 2" aluminum
High Density Foam Pads (the packing foam from Castle or Turnigy ESC's work great!!)
Double-Sided Tape
Cutting Tool (saw, rotary, grinder)
Countersink drill bit
Torch (propane or map)
Bench Vise
Hammer
Heat resistant Gloves (welding)
Measure battery to be used and add 2-3 inches of length and cut the aluminum.
Place battery in center of cut aluminum bar and mark bar approximately 1/4 - 1/2 inch on either side of the battery.
Now heavily mark the bar again 1/4 inch further away from the battery than the first marks.
Place battery aside and clamp the bar in the vise such that the heavy mark is at the top of the vise jaws.
Steadily heat aluminum at the point where the jaws are clamped until the aluminum becomes extremely reflective.
While still hot, bend the aluminum bar to a right angle while using the hammer to create a tighter angled radius. ***do not bend too quickly, the aluminum may crack***
Mount using existing holes in the chassis if possible, if not drill holes in the chassis countersinking the holes to maintain a smooth underbody. 
Use a piece of scrap paper to mock up the location of the holes needed in the battery tray.
Drill out the holes in the battery tray and secure with appropriate screws and lock-nuts.
Cut foam pads to appropriate size and attach with double sided tape.

Enjoy your new secure and lightweight battery tray :-)

UAS Registration

Just got my small UAS registration cerificate. Don't really need it for the Alias, but I figured what the hell. Now I have to label the quad with the number, to make it officially registered.

As a precationary measure, i think I should label my speed runners too. They seem to spend more time in the air than the quad does.

Shannon's Alias

I wanted to find something fun for my wife, Shannon, to play around with to get her involved in R/Cing. An old friend and her husband visited us a couple weeks ago and showed us footage of their quadcopter and Shannon exclaimed, "I want one!". So, the next day I ordered one for her.

Looking into the vast number of quads available right now, I had to narrow it down to the most practical unit for a beginner. At $100, the LaTraxx Alias won by a landslide with its availability of spare parts, Traxxas customer service and it's simplicity.

The basic unit is pretty bare, but for $250 shipped I got: the Alias (the quad itself with spare blades, controller and battery), an extra canopy, rpm blade guards, rpm landing gear, the 720p Alias Camera unit, a wide angle (120°) camera lens, an extra LaTraxx battery, 2 more batteries (lower mah, but higher discharge ratings for faster speeds) and a 3rd set of blades. The only thing I didn't get is a micro SD card for the camera, but we have plenty of spare ones from our old phones and tablets.

So, Shannon and I put on the rpm landing gear, charged the batteries and read through the directions for the maiden voyage yesterday. I had my fingers crossed that she would fall in love with the cute little quad. She was a little nervous, but fired it up and had had it hover for 10 seconds before nailing the throttle and sending it over the neighbors house, over some trees, and out of range. In a flash, $250 disapeared...shit!

The super-bright leds on the quad made it easy to find (three houses down the road) and there was no damage from the fall. The maiden voyage was short and scary, had it flow a little further it would have landed on a fairly busy road possibly meeting its fate under the wheel of a passing car or worse yet, causing an accident. Both of us were pretty freaked out how quickly the Alias ran away.

After recovering the little hellian, and re-reading the manual (this time acutally reading and not just skimming through it) I saw that it was set on the fast mode...ugh! So, after charging up the 2nd battery I took it out and managed to keep it within visual range however, I did crash into everything I possibly could (bushes, fences, poles and of course the ground).

Shannon is still a bit freaked out and scared of breaking it or breaking something with it, but I hope she learns to enjoy it. Once she get comfortable enough with the Alias we will install the camera and I really think that will get her excited about it again, making flight movies of the house, the neighborhood and our kitties.

I know that I will never be a great pilot (I can barely control my cars in 2 dimensions), but I really think with some practice and a little more confidence she will become an expert pilot and have some real fun with the LaTraxx Alias. So, some day (hopefully by next summer) she can film some of my 100+mph passes with Kake and the Dirty Little Sisters.

My thoughts on the Alias...

It seems to be a great starter quadcopter, though I do wish the controller was a bit more intuitive. I hope to find a way to make the controls more sluggish (at least the vertical control) to prevent another fly-away. The frame is quite forgiving and flexible, and the leds are very bright. The motors and drive gears seem a bit fragile, but so far they haven't crapped out. I really think that the motors should be brushless to increase motor life expectancy as I can already see a new set of motors will be needed soon. Also, it looks as though the rpm landing gear is a neccesity for beginners as the original landing pads are nothing more than tiny rubber stoppers that don't provide much protection to the motor stocks when landing (or crashing).

...in the right hands this quad can be spectacular. With the camera, i can imagine that it will be a great little video maker. We will see how much abuse it can take over the coming months, and I will try to keep a record of flights, repairs and Shannons' improving skill on my site.

The Speedrun Family

I set up a rack in my Garage to hold my speedrunners. On top are the Dirty Little Sisters (custom rwd XO-1's). The third shelf is holding Marley (Ofna Hyper SSTE). Under that is Kake (a converted Proline Pro-2 (or upgraded 2wd slash)). The bottom shelf houses Mobius the Ofna 3GTe with his 1/5 scale GRP's.

Hopefully by the end of summer I can get them all up to fighting condition...

Dirty Little Sisters: the wait continues

The pics show the current state of the sisters. I did receive a Kershaw pinion for DLS 1 the other day, but I am holding off puting it in until I have some other (non r/c) projects completed.

Some of you know that my 2012 GTI ate its own engine so I have been preoccupied with dealing with the warranty repair on that. I have also been working crazy overtime lately, as well as completing projects around the house.

Next up for the sisters should be a test run on 4s for steering and gearing. Then the body reveal along with the final build video. Hopefully September I will be able to stretch their legs a bit and start the comparison runs.

Cowboy Custom has been working hard on First Degree (can't wait to see the numbers he puts up). So good luck to him and all the rest of you trying to get downtown and back.

Make it till you break it!!!
