Well.. I've been working on some new airfoils and a friend suggested "Why not try one of the small ones first?"
Hmmm.. At almost the same moment he suggested it, I was sitting right next to a partially build core set and thought.. "Ok."
Grabbed a 2730-3000 and a 4.75x4.75 prop, 25A Plush, 3S 900 45C battery and some HXT-900 servos and a lil' Orange 4 channel RX and went town..
I was hoping for a solid 75mph.. I got it. Cruise "3/4 throttle" speed is 75mph all day long according to RCSpeedo. She's good for about 95-100mph at WOT, which isn't too shabby for a 20" span, flat bottom airfoiled bird.
Had to give it a go on 4S.. Swapped out the 4.75x4.75 with a 4.1x4.1 and let her rip. The Plush is having a fit keeping up with the motor and I can't even hit WOT with it, but it was visibly faster.
Not sure why I never threw the video of this up here, but here it is:
Well, my first squirt of CA left me with a horrible headache. Several years ago the wife and I suspected I was allergic to CA, well, she did her "toldja so dance" so I pulled out some wood glue and went to town..

Ok, so the big bag guy towards our CA is moisture. Moisture in the air is what kills our CA..
An easy way to keep our CA alive a little longer is to try and remove the moisture in the air.
I ran down to Wal-Mart and picked up a Sterilite 12 cup container and a couple bags of rice. I've also been saving the silica packets that come with all sorts of electronics. I knew they'd come in handy someday.
So.. Get your container with a gasket..
Throw your silica (if you've been saving it) into the container..
While I was there I had 2 planes go in.. One of which, I'll take the blame for. I figured it was totaled. I watched it BOUNCE what looked like at least 10' back into the air when it hit. Found the crash site and gathered up the parts. Not too many parts, but the plane looked thumped. Figured it was totaled, which really bummed me out. The IYF is one of my favorite birds..
Brought it home and checked it out, it looked like it could be repaired, so I thought I'd give it a shot. Wound up with a new trim scheme on the top but kept the old scheme on the bottom. I didn't have any of the original red covering, so there is a bit of a color mismatch, but it's flying great, I'll live with it.

I've bounced back and forth over the years and had a car here and a car there.. Well, I've been thinking about picking up another car lately..
Last week my brother-in-law won a Traxxas Rally Camaro from the local grocery store and decided he wanted to sell it, so he brought it by the house and left it with me to put on RCG to sell.. Well, I couldn't very well sell it without knowing how it operated, of course, so I ran a handful of packs through it.
It was an absolute blast. Being an on-road car, I couldn't hit the grass with it, but what little running I was able to do was a lot of fun. I knew I had to have my own..
Enter Merv. Merv is a 1/16th scale E-Revo. A scaled down mini version of it's bigger brother the E-Revo. Merv. Mini E-ReVo.. However, my merv is no normal merv. It has been upgraded in most places where an upgrade is available. It's sporting a Castle Sidewinder setup that is suitable for 1/10th off road vehicles. It's had 75% of the plastic components upgraded with aluminum this and steel that and it'll do close to 65mph.. Yep.. 65mph.. It will wheelie at half throttle..
Wow.. This thing is fast..
Got a few runs through it before I broke some stuff.. I went through 2 knuckles pretty quickly. I also killed the center drive shaft, but that's ok, as I have some HR Knuckles already on the way and a GPM center drive shaft.. I got the car back up and running with some spares, so I can keep bashing until the parts get here..
These things are getting cooler and cooler.. I've always liked the way they looked.. Just looked like they would be a ton of fun to play with.. Well, I stumbled across troynh's TriCopter build and thought I'd throw one together..
troynh has a ton of good info in his thread about his tricopter with a scan of his fuse and everything.. I drew my own based on his measurements..
One of the "hardest" parts of the tri builds that I have seen is the issue with the yaw motor. Most guys go from very simple to very elaborate setups.. After looking at troynh's videos and his yaw setup I thought this was the best setup I had seen..
It's very simple. Uses some 1/4 threaded rod, CF arrow shaft and some pushrod of your choice.. The following 3 pictures will show the basic setup..
I've been asked several times to put up some pics of a few of the ARF's we've built for customers.. I haven't been taking pictures of them until recently and thought I'd throw them up here.....Continue Reading

Well, the mailwoman rocked today.. Brought me some really nice goodies..
I am currently working on converting a Saiga 12 shotgun back to it's Kalashnikov roots.. Modern guns cannot be imported into the US with the "evil" pistol grip without meeting some standards. So the easiest way around this is for the weapons to be imported in a "sporter" configuration.
This a Saiga 12 made in the Izhmash plant on the same assembly line as moden day AK weapons. Old man Kalashnikov still works there in Udmurt Republic, Russia..
In order to convert it back to a pistol grip weapon, there are several items that must be replaced to be compliant with 18 USC 922R, more often just known as 922r.
I'm going to replace quite a few things on the weapon.
I'll be adding:
Magpul MOE Stock
Vltor Ak-47 Stock Adapter
Magpul MOE Grip
Magpul Angled For Grip
Tapco G2 Trigger group
JT Engineering AR-15 grip adapter for AK platforms
AGP 10 round magazine
Chaos Extended Quad Rail
Chaos HK Sights
I'm still waiting for my Chaos rail - should be here tomorrow and my Vltor stock adapter which should be here Wednesday..
I figured I'd just make this a "build thread" of my Saiga 12.. No, it's not RC, but I don't think anyone here lives and breaths RC and only RC..
So.. I should start with a picture.. The gun and most of the components.
I had a little time to fit some of the parts.. The Chaos rail arrived.. Just playing..

I get this question pretty often..
What prop? Well, the answer to that, is at first, a question.. What size pack are you running? 2S? 3S? 12S?
I fly the SF mostly on 2S.. I just like it that way.. It rocks on 3S but becomes a different animal. Much faster and obviously has more punch..
The Fly was developed to fly on 2S, the Etec 1200 was the battery of choice at the time.. However, the HD props were not even around yet and GWS SF's props were being used..
If you are going to run 3S the 8x4HD would definitely be the prop to run, if you cared about treating the motor properly.. Otherwise, you may melt the stock motor.
As far as the 8x4 vs 8x6 deal..
The only area the 8x4HD loses to the 8x6HD is in top end speed.. As it should..
The only place the 8x6HD loses to the 8x4HD is in low end thrust.. As it should..
On 2S I read the following:
8x6 Peak amps of 13.6 @ 102watts..
On 8x4 Peak amps of 12.31 @ 83watts..
The 8x4HD blows the 8x6HD out of water in the thrust department.. It does give up ground in the speed department..
In the charts, the 8x4 appears to have given up the ghost sooner.. I wanted to do a "duration" run as well.. It's obvious by the numbers, the 8x4HD would last longer, but that's assuming you can keep the plane out of the trees.. I killed my prop and being it's snowing outside, I came in..
SuperFlyRC.com will keep both props on hand so anyone can make the proper choice.. If you are going to be running 3S, let us know.. We'll make sure you get the 8x4..

Well.. I've been looking for a FVK Bandit for a while and they go so fast that I was having a hard time, so I wound up finding a "previously bashed" one for pennies.. Extremely cheap, so I bought it thinking I would just fix it and learn something in the process..
I haven't done much fiberglass repair, but the damage looked slight enough that I thought I'd tackle it..
Dave or shhhhh! here on the groups does these repairs for decent trades, so if you have a busted bird you don't want to fix yourself, shoot Dave a message..
I'll be trying to repair mine soon..
Need to snag some Z-poxy and some micro balloons..
