My last post about hobbypartz gave me the idea to see if they are as great as I think they are, or if they are pulling the ol' bait and switch. Don't get me wrong I love hobbypartz but the fact that a lot of things have are out of stock and from what i see are never in stock has given me an uneasy feeling. The subject will be a 55mm to 64mmEDF to replace my broken EDF's trying to stay in the $20.00 price point

These are the top results from a google search for online "rc hobby store"

Hobby King:
EWS64 no specs listed on site. User review said 230gr thrust at 11.1v Too weak $12.50 plus shipping. Couldn't find shipping cost unless I registered. too much work
AEO 55mm exactly like the ones I am replacing $15.12
AEO 64mm 19.969
unknown brand 55mm little data listed $17.40
Hobby King 50mm alloy (I want it) $19.95
I went ahead and registered. 3 of the alloy 50mm with shipping is $69.84

Overall hobbyking has a good selection and in stock, but not the cheapest prices, and no free shipping.

AEO 55mm the same one I bought from them before not in stock. $17.70 3 with free shipping $53.10
AEO 55mm same price with less performance
AEO 55mm same performance as what I bought before but over $2.00 more per unit $59.85 total
No 64mm units in stock

Prices are great, selection not as good, availability not so good

exact same products as hobbypartz, prices considerably higher than hobbypartz and hobbyking (not much in my $20.00...Continue Reading

I really like the hobbypartz web store. Prices are great for a beginner on a budget like me. Also the free shipping is great. The biggest problem I have is that it seems like I am interested in the most popular items because they are always out of stock. Some items have been out of stock since I started visiting the site and have never been in stock. I sometimes wonder if this problem carries over to other on line stores. Or could hobbypartz be pulling the ol' bait and switch. I have always received good service from them, and shipping has always been spot on. Never more than three days shipping. Another thing I have noticed is that some of the items out of stock at hobbypartz are available on their "affiliate" sites for a higher price and no free shipping. I am going to do a little looking around at different suppliers and investigate this further. Maybe my next post will be a report of my findings.

Let me start by saying I am not even close to an expert with Arduino. Iam barely a beginner. However Arduino lead me to the multi-wii stailization system, which led me to Crash Mans' QSC tricopter, which lead me to my current tricopter. I read in a post where somebody asked what multi-wii was. That lead me to realize that in my first blog entry I mentioned Arduino, and some people may not know what that is.

Arduino is an open source microprocessor programming platform that is inexpensive to start experimenting with. My first use for an arduino was making LED's blink or strobe. I dabble a little in model trains. I became more interested in buildings and vehicles than the trains themselves. I have always been interested in rescue vehicles and I was coming up with circuits that incorporated as many as five or six 555 timer circuits to get the flashing strobing effects I wanted. The electricians I work with would alaways ask "Why don't you use a basic stamp, or pic ?" I had no intention of spending the amount of money required to get started in either platform. Then I read about Arduino. An arduino board can be built very inexpensively from plans available free, or bought at Fry's Electronics for $20.00 if you are a cash and carry person like me. All of the code is free, and there is tons of example code out there for free.

Arduino can do more than just make LED's blink even though that's my favorite use for them. I have done other projects. I made a robotic...Continue Reading

I've never had a blog so I thought I might give it a try. Not that I have anything that interesting going on. Here goes.

I wanted to talk a little bit today about my first tricopter. If you want a good place to start and have absolutely no experience like I did then check out the QSC tricopter. Just do a google search for it and you will find it. The creator Mike "Crash" Hancock does a spectacular job of taking you throughevery step of the build process. It also includes detailed step by step instructions for assembing your own multiwii flight stabiliztion system. Also included is his multiwii config file to help you get started with some of the setup. Although he is using an older version of the multiwii "sketch" (code if you're not familliar with Arduino terminology) It functions perfectly for this build. I looked at more current versions of the sketch and there are a lot more advanced variables that I had no Idea how to use being a noob. I can tell you from my own experience that the instructions are so detailed that I was able to build this thing with ZERO experience, and a few common tools. Furthermore it is very stable, looks pretty intimidating, and is fun to fly. So check it out.

So there it was. Don't know if anyone will read it. I was trying to come up with a clever closing line like "keep it in the sky." or "if you can't keep it in the sky keep it in the hangar.", or "keep your trays and seatbacks up, and your wheels down.

Next time, a little bit about Arduino.
