I know this has very little to do with radio control airplanes whatsoever (it is however my only mode of transportation to and from the local slope, which requires a 4x4), but it's my blog so I figured i'll post it anyways.

Was driving to the local slope to get more stick time in on my recently acquired HalfPipe (not mine, but I might as well fly it anyways) when I heard some bad vibrations and noticed smoke coming from my rear left wheel. Was going to pullover as soon as I could to turn around and reluctantly head back home (about 2 miles).

Next thing i know I'm hearing a bad vibration from my rear axle. The next moment I heard a loud SNAP as I see my wheel and axle shaft rolling past me, and then it dawned on me that I was in deep crap when I felt my rear axle hit the ground. Since the wheel was off and it took the brake drum with it, my brakes lost most of their stopping power because the rear cylinder was extending out all the way. FORTUNATELY there was enough stopping power to skid to a stop on the one small stretch of dirt in the road for a couple of miles. Even more fortunate is that it parked itself in a location that most could easily see, but with the speed limit being 55, and everyone not giving a care in the world, it hardly mattered as the not so intelligent residents flew on past me. Even with a police officer there directing traffic, people were still hauling quickly.





Anyways, I plan on doing an axle swap. Jeep for some reason decided to include a light duty rear axle with YJ and TJ Wrangler models (except for rubicons) and my axles time just happened to come yesterday. Going to swap in a Ford 8.8 axle out of an Explorer, hopefully one with disk brakes for more stopping power when offroading. Have yet to find my axle shaft and wheel (it was a decent wheel too, would make a good spare even though it's very close to being bald).

Well, after digging through some stuff today, I came across the beaten and slightly bashed Mountain Models Slipso fuselage I had placed inside a box for when I was moving. I remember working on the wing a year and a half or so ago, trying to give it a nice smooth airfoil, then coat it in epoxy and give it a nice finish

Welp, dug out the wing, and taped it to the fuselage ( ), and am going to work on it tomorrow or sometime, converting it to a nice micro sloper (or maybee back to a high speed plane..)

Ok, made another battle bot today, using more HS55s. They still have the stupid wandering problem, so it's impossible to center them. But it works good

The flipper arm I have can easily flip a 75g box, which is good because the max weight is 75 grams for bots.

Here's some pics. I'll make another entry with a video.

Also, here's a video of a saw i'm working on to chomp through bots and flip them all around

Okay, so i made this little guy today for battle at an upcomming show.

They're pretty easy to make, and only require a few simple things a lot of people might have lying around.

Materials list:

Pieces of 3mm and 6mm dperon (or cardboard)
2, 7-9 gram high speed servos
Scraps of carbon fiber flats, or balsa wood (for strength)
Hot Glue
Micro receiver
2s 200-400 mah lipo
Small BEC
Small motor with Rx connector wired up (for a simple saw)
Elevon mixing

Now, you can build pretty much any shape robot you want- I myself am going for a small design under 75 grams, and smaller than a 4" square box (for the competition).

First step is to modify your servos, so that they will drive continuously, and not stop when you push the sticks to the full (they will stop moving once at center).

Follow this link for step by step instructions to modify your servos:

Once you have done that, you can now either make some wheels out of foam or cardboard, and glue them to a servo arm, or cut some pushrods the same diameter as the hole in the servos output head, and use some wheels that have the same diameter hole as the axle, and glue them into place (carefully! you don't want to freeze the output head in place!).

Now, assemble everything onto the chassis, and then begin to build foam around everything. First, make the sides of the bot, so nothing gets in the way of the wheels. Now, make the front, and rear. Typically, you...Continue Reading

After being a member of RC Groups for 2 years now (I joined in October 2007), I have made 10,180 posts, or 5,090 a year, or 424 posts a month, or 106 posts a week!

Thanks for the fun RC Groups! It's been an awesome 2 years.

Well recently being moved from my old workshop (as well as my big flying space ), I had to setup a new one. Luckily, the new house I've moved to had a basement room that I'm using as a current workshop. There's just enough space to store all of my gear in there, and have a good space to work on.

I've only built (well, rebuilt) one plane on it sofar, and it's working good sofar. Gotta add more pegboard on the workshop wall, and all the holders for all of my tools. Also, probably going to build a charging station, when I get a few more chargers.
