So what had happened was...

My father in law, who is chief of police at a university in Houston, always hates it when his officers start telling what they did with that line. I figure it's appropriate here.

Years ago I was into helis, first with a Trex 450, then a Shuttle 30, and a Raptor 30 that became a 50, but life interfered and I sold them all and did supposedly more productive stuff for about a decade. A few years ago I was off doing my job, chasing bad guys and keeping the donut population in check, when I fell across a handrail and destroyed my spine (the final score is ~75% loss of use of my left leg and inoperable level 5 tears in L4/5 and L5/S1 discs), so I got back into RC since I wouldn't be doing much else for a few weeks. Weeks turned into months, which turned into forever, so I've been expanding my collection and decided I wanted another heli, not counting coaxes and the likes.

First was an HK450, which was mainly an exercise in seeing if $30 heli would fly. Surprising it does! Then I stumbled across a deal on an E325 V2 FBL kit and snatched it up. Then a Blade SR on clearance.

Those were all fine for hovering in the driveway, but I wanted bigger, so I made a deal with Madgadget and acquired an E550 in very good shape, just add a motor, ESC, and battery. Specifically, an Align 600MX 1220 KV, Ice Lite 100 I had sitting around, and a 6x5000 lipo.

Being the type that can't leave things alone I started changing things immediately. First an X50 boom and belt, and now I'm working on black and orange carbon sheets, laid up with the redneck vacuum bag (a Foodsaver), from which to cut new fins.

So that's where I am now, waiting for resin to cure. While I wait, here are a few pics.

First, a pic shamelessly stolen from Madgadget showing what I started with:

Just for kicks, my old R30 with an R60 canopy:

After a swash servo scare caused by my test battery being near dead, resulting in my buying new servos I don't need, which will be returned and put towards a DX9, and getting the gyro set up, I think, she's ready to fly. Before that I really want to know if the gyro is behaving right.

I have the slider set to 4.5mm from the tail box in rate mode with the stick at neutral and the gyro limit set so the slider is barely hitting the box at full throw, but there's barely any travel to the right (left stick). There's plenty of room, nothing is binding, there is no subtrim, ATV is at 100, rates are at 100, and the servo arm is at 90° to the pushrod. Is that normal?

I also ordered an E550S canopy and will make it fit even if it doesn't want to.

The carbon sheets are mostly cured, just need to give them some time to get good and hard and I can start cutting fins. Next time I lay up some panels I'm going to bag them sandwiched between aluminum and plexiglass plates just to make sure they stay flat on both sides. ID rather do it with an RTM setup on a granite surface plate, but that's all expensive.

I'm debating making a set of carbon gear legs. I can cut a suitable mold out of MDF and add some unidirectional carbon tape between the black and orange skins, but the holes for the skids might be a pain. Maybe wrap the ends around some very slightly tapered delrin pins? I need to do some thinking on that plan.

Another possible plan is a matching boom. To pull that off I'll need a very precisely turned mandrel that's double the thickness of the carbon sleeve and the release paper I use on the inside to make it possible to remove the part from the mandrel smaller than the OD of the boom. Not easy on my lathe and not cheap to outsource, but it'll make for a pretty unique boom. I could also cheat and taper the boom with aluminum ferules bonded to the ends to get back to the right diameter. More thinking to be done there, too.

But now it's time for sleeping.

I'm awake, more or less. Did exactly nothing today, too windy to attempt to hover and tune the gyro, but I managed to spool her up last night. I think the headspeed is a bit high, but I don't have a tach to verify the 1600 I requested is what I'm getting. I really wish I could figure out how to set up the Ice Lite to work like the gyros in my MD500 and E360, where throttle position sets RPM, instead of going in and telling the ESC the specific RPM I want. I assume there's a way to do it, but I haven't figured it out yet. It would make tuning much easier, and the hover throttle trim in the 8U would work. I'm also wishing I had an Ice 100 instead of the Ice Lite 100. Mounting it would be much easier.

The Protos 500 canopy I ordered to replicate large enough to fit the E550 showed up today, and the E550S canopy will be here tomorrow. With any luck it'll bolt right on. I'll just save the Protos canopy for the Protos I'll eventually have

The carbon panels are continuing to cure. I've been too lazy to figure out a good way to post cure them, so im doing it the old fashioned way and letting them sit. I have enough for the horizontal stabilizer, which will be a bit bigger and cut to match the blade tips, the vertical stabilizer, which will have more area above the boom, and some various electronics mounting plates (ESC, BEC, and maybe part of throw tail servo mount). I've been thinking more about the landing gear and I think I'm going to make the attempt. Since I'm starting from scratch there I can change whatever I want, so I'll add some width and change the taper a bit.

I need to start shopping for an FBL head. I'm thinking RJX, but what I really want is the E325 FBL head blown up to fit. Absolute minimum of components. If I still had a mill I'd just make one that uses of the shelf grips and feathering shaft. No need to reinvent the wheel there. Actually, I might be able to do it on the lathe with some creative setup. I'll have to think on that a bit.

Oh yeah, does anyone know the detailed specs on the Align 600MX 1220kV motor? I need the internal resistance and no load current.

Right before heading out of town for Cub Scout camp, which was fun, but way too far from the restrooms, I acquired two things that will be used with the E550.

First was the E550S canopy. I didn't get to mess with it until today, but it will fit if the gyro is moved down to the receiver area and you work at it. The front corner of throw lower frame hits the canopy, but it'll just barely fit. I'm working on ways to make it fit better now.

The second was my greatly needed new radio. The 8U is perpetually full and I don't really trust the 9X with expensive models, so I fetched myself a DX9. 250 memories and an SD card will ensure I have space for a long time and the wireless trainer system will, make life much easier.

5 minutes with an angle grinder and the E550S canopy fits perfectly. 3 hours with the pitch gauge, laptop, and manuals for both the Raptor and radio and the DX9 is programmed. I spent at least half an hour figuring out that you have to set up throttle cut in addition to the flight modes to get the throttle to work in normal, idle 1, and idle 2. The Ice Lite 100 is calibrated and set to governor high, and the curves set to 1575 in normal (that's as low as it can go), 1700 in Idle 1, and 1900 in Idle 2, +10° of collective in all modes and from -4° to -10° depending on the mode.

I need to figure out a way to attach a small level to the flybar and glue another to the pitch gauge. Much easier than lining up the flybar and gauge, and much more accurate.

Pics later, I need a nap.

If you're working on a E550 with a 1:1 flybar ratio, no need to level the flybar.

I didn't think about that. Does the E550 have a 1:1 flybar? It seems like it, but I'd rather make sure. I do need to figure out a good way to get the main shaft perfectly vertical, though. If it's off a couple of degrees because the table isn't level, then the pitch will be off, too.

The 550S uses the same seesaw as the R30-50(PV0486), so it's 1:1.

Thanks guys. It's been a very long time since I messed with any of this stuff and, unfortunately, learning the Texas Penal Code kinda forced the good stuff out of my brain.

Being the cheap guy I am I'm going to make one attempt at building a pitch gauge that holds my iPhone or iPod. Run level app, zero on the bench, and stick it on the blade. If that fails I'll order a digital pitch gauge.

And I finally figured out, more or less, what FBL gyro I'm going with: the IkrainX Whichever of the 3 I find cheapest is getting ordered tonight, along with a new head and a few other bits and pieces. Yes, I'm a weenie, I want auto leveling and a bailout button.

Can't remember if I mentioned the paint job, but that's in progress, too. I ordered a few meters of a couple of different hydro dip films that should be here this week, just in time for another spine surgery, yay. The plan is urban digital camo on the top half of the canopy, black and orange tiger stripe below that, and, if I can figure out how to do it, digital urban on the boom.

I found a near feature in the DX9 that will make tuning the gyro easy. The trim switches above the gimbals can be set up as various things, like gyro gain and when used for that, it only changes the gain for the mode you're in. Very cool design.

So I got impatient and went with the Thunder Tiger FBL conversion, which is a gorgeous hunk of aluminum. It got here yesterday and the Brain showed up today, a day early, so I started tearing things apart. Off with her head, swap the main shafts, new head on, and discover that TT changed the links. That doesn't look like a turnbuckle to me, but it does look like titanium, so it's just going to be a bit annoying until I hunt down some 2" Ti turnbuckles. Now I'm up to my eyes in programming. MSH, include a printed manual for God's sake! Some of us haven't done this before and figuring out which servo goes where and what swash is right isn't easy. More later after I get it done or have a nervous breakdown.

With any luck I'll be able to mess with the hydro dipping stuff tomorrow. I have a pair of Ergo 1911 grips and an HK450 canopy ready to dunk as practice. If they work out the next step will be the E550 canopy.

Now the latest issue. I'd like to put in some stronger, metal geared servos, but im cheap. Then I remembered I have Savöx servos in a car and truck, two SC-1258TGs and an SC-1257TG. So the plan is to order a third 1258, steal the ones I have from their current vehicles, and throw them into the Raptor. 166 oz. in. should do it That will also let me use some adjustable servo arms I found.

I've used them on the ground quite a bit and if you need a fast servo on a 4 wheel drive truck that isn't a crawler, they work great. Crawlers need the torque more than speed, so I go with Hitec 7954s, usually. In the air they should be great. Fast with plenty of torque, and the rotor will cover the noise They are loud and need lots of power (4 amps stalled), but I have a 20a BEC in the belly so I should be OK.

Stopped by one of the LHS's Friday and noticed a couple of boxes stuck in a corner. Both were X50 FNP canopies, so I asked what they wanted, not expecting to like the answer. $20 each. Yup, they both came home with me. One is the orange and brown scheme, the other white. The white one is masked and wet sanded to 600 grit and I'm about to shoot a coat of primer, then mask the top half and shoot a coat of gloss black on the bottom half, then some Alclad II polished aluminum or stainless steel. The top will get white paint, followed by digital camo hydro dip. A couple of coats of clear to seal all that, then panel lines, nose art decals, etc., and a couple of finish coats of clear.

Still working on the camo. I'm hoping to get the vertical fin done and back on tomorrow then, with a tiny bit of luck, fly the thing this week. The weather has been just plain lousy the last few weeks.

I'm getting frustrated. I don't know if it's the base coat paint, the temperature in the garage, or what, but the hydro dip on the vertical fin is fighting me left and right, literally. The left side is done acceptably well after 2 attempts, the right, not so much. I'm going to eliminate one of the possibilities by getting out the airbrush and some white enamel paint. A light coat of that to seal the previous base coat will at least tell me if the old paint is the problem.

Here's the Raptor, Blade 500, and E360. I'm trying not to let the 500 take up all of my Raptor building time. The gyro got swapped for the 401 that was in the Raptor the day it got here and I started swapping the stock 70a ESC for a Castle Ice 75

I have no idea what this is, but I want one:

And here's an idea I've been wanting for about a decade. I've been thinking about modifying an HXT-900 I have sitting around by unsoldering the cable from the board, cutting a slot, and soldering in a header, then using a female to female servo cable to connect it to the receiver. Same concept as these servos, but I'm sure much cheaper. The only problem is figuring out how to make the header since the pads on the board aren't spaced right.

Finally got some air under the skids today, though not much. She's just too big to hover in the driveway now. Extremely stable, though. At least as stable as with the flybar, but with no lack of authority, so I must not have screwed up the Brain setup too bad. Tomorrow morning I have to go see the doc yet again, but the afternoon is wide open and the weather looks great for the commission of aviation. Before I do that I have to figure out how to strap the Raptor and B500 to the bike trailer, though. I'm too cheap for Random clamps, but I have some 6061 Al flat around here somewhere. I think I can make something work with 6 long bolts, 6 wing nuts, and a couple of 1x.25 straps.
