Evolution 10cc DISCONTINUED

Working on the Evo 10cc, snugged up the exhaust extensions which were leaking a bit, and wanted to snug up the carb screws. I snapped off the fuel nipple trying to tighten it. That's when I learned Horzion Hobby has discontinued the engine and that the nipples are NIS. Crap. Found some at GravesRC, got two, for about $6, but shipping cost $8. Damn. I could not get the retaining bolt off the engine case to remove the carb, it stripped its cap. So I had to grind a line for a slot screwdrived and got that off. Turns out the screw is an odd size M2.5 16mm. So I had to order some from RTL Fastners. Jeez.

I did see that the guide screw for the barrel throttle wasn't quite right so the throttle did not close. I greased it and adjusted it, now it has full smooth range of motion. Broke out the manual and set the screws back to stock settings, High is 2.5 turns, Low is a whoppjng 4.25 turns. Once I get the fuel nipple and the 2.5mm clamp screw in, I can put it back, redo the fuel lines (there is a leak somewhere, maybe it was the carb).

So HH has discontinued the 10cc. Huh...

UPDATE 10/16/19: One of the reasons I really love Horizon Hobby is their incredbile customer service. Yesterday I left a note asking about HH having d/c'd the 10cc Evo and my being at a loss for a fuel nipple. Dave Poole the Service Manager has one laying around and will have it sent to me gratis. I love these guys!

Flying with the big boy...

Took the Sbach and its unreliable Evo 10cc, and the very reliable though sometimes hard to dry start RCGF-USA 30cc MX-Bach. I took the MX-Bach up after several minutes hand flipping her. She ran very reliably, and I took her up for a few minutes. She flew wonderfully, but I really don't like to fly in front of a crowd, especially the incredibly skilled Cody. He would never make me feel uncomfortable, it's all me, in my head. But I mean, Cody Wojcik... come on! So I landed and set her aside for a bit. I then took up the Sbach with its Evolution 10cc, which started and ran fine right away, but after a few minutes of flight and light aerobatics, quit. Dead sticked to an acceptable landing, tore off a wheel pant, but otherwise she is fine. It took some time, but I got her started, but in idle she would slow to a stop. Cody wanted to help but I really didn't want to take his time as much as I wanted to let him fix her. He came to fly with a couple of visiting quad pilots, I think to video. I took the cowl off and tried to lean her out, as there is is oil all over the wing, suggesting its rich as I have always thought, in fact, the low was 4-5 turns out! But she wouldn't turn over with anything less. I managed to make her not want to start at all. I decided to set her aside, and watch Cody fly his Extreme Flight DA 120.

I caught a few moments of Cody's flight. I wanted to watch more than video, so I only caught a few unremarkable moments. Watch his fingers. He makes this huge plane float, every movement is what he wants, not what he accepts. I have no desire to 3D, but would love to someday have that confidence. Oh, and the engine started with one flip. I had not intended to stay long, and was a bit pissed about the dependability of the Evo, so packed up and left them to their fun! I did get to watch one of the FPV Quad pilots tear through the air as I packed. WOW! I have seen videos, but this thing screamed. Fun to watch!

Looks like I have some work to do on the Evo.

Surgical or "Huck" Towels

I have used surgical towels as a work top "bounce suppressor" for years. This one is several years old. I wash them every so often, but eventially they need to be replaced. They absorb liquids like oils and glues, and keep screws from launching into the abyss. I never knew they were called "Huck" towels, nor why.

I just bought a boat load from Amazon, here is a nice new blue hone. No nap, no snag.

I will never need to buy another one again. I prefer these as they are not like build towels that snag eveything and get pulls, and they are cheap so if they get stained it's simple to toss and replace with a new one.

Flying blind

I made the mistake of trying to fly with my glasses instead of my contacts and I made this decision on an overcast and sprinkly day. I don't see as well with my glasses.

Took the freshly rebuilt HK500 FBL up. It went about as good as one might expect. Lost orientation, limited heli skills, yeah, a mess. I dragged the new canopy over for the pic, it having gotten tossed far afield. I know I need more sim time, but I want to get comfortable with flying the actual heli. I was doing fine, 4 min in to a nice basic flight, sometimes having issues getting the tail around. I was outbound, a bit far away, and lost control when I wasn't sure if she had turned nose back in, she drifted and I made things worse. That was the end of that.

I already have most of the rebuild done. I have to order a new belt, it broke in the crash as the tail boom separated.  Replaced the main shaft, the feathering shaft is fine. The tail shaft will need replacing. Lost a control rod, replaced it. The canopy took quite a lot of damage, glassed in some repairs.

The tail boom is 461mm long. The tail belt is labled as 400mm. Not sure how that works... We'll see.

I also brought out the MXS-R with its 30cc DLE. Took a bit to start, haven't run it in a while. Took it up and even that big plane was a blur, not enough orientation in this light with my glasses. Landed, called it a day.

Disappointing.

Well, that's a thing I know now...

For a number of years now I have whined about off brand EC5s not going together right. I don't know how I got there, but I read a thread about EC5 gripes on one of the rc groups, and someone commented that the off brands often go in backwards from the Horizon Hobby originals, that is, you don't press them through the back, you instead rub the wires through the plastic, solder them, then pull them back through the front.

I just got two new batteries, so tonight I did that and they went together simply...

Damn.

HK500 has a new lid!

KILLER!
