Re: Let the 185 mods begin (again)

I ordered my split cuffs from Willie at Stene. Good part and would recommend. I will try to shoot some pics...

Will be very interesting in the coming years with the EarthX and the cold weather, cold soaked starting. Please keep us informed on the approval of this or if you have to do it after the fact. Thanks! Greg


Where is your battery mounted? Most of the 170's I've been around have a firewall mounted battery box. With that, the battery is never cold, assuming that the engine is pre-heated of course.... :lol:

BUT, I flew three different Huskys in interior Alaska, all of which had Odyssey batteries, and all were mounted in the standard location...far aft, behind the baggage compartment. None of those airplanes had battery blankets/heaters installed. I parked those airplanes outside in VERY cold temps, and cranked at temps as low as -40. Those Odyssey batteries always cranked enthusiastically, every time, cold or warm.

If you're having cold issues with an Odyssey, I'd check to make sure the battery hasn't been totally discharged and then improperly re-charged or???? Every one I've used has been MUCH better in cold than any "standard" battery. Or, that it's getting fully charged when the alternator (you do have an alternator, not a generator????) is running. I'd bet that battery isn't fully charged, or is damaged somehow.

Before we started using the Odyssey batteries, we put battery heaters on the batteries when operating in the cold. Either a battery blanket heater or one of the battery heater plates that sit under the battery. Those were wired into the engine heater plugs.

Most batteries won't take a charge when they're really cold...or at least take a charge at a very slow rate. So, getting the battery warm really helps to recharge. But, again, we quit using the battery heaters once we switched to the Odyssey. That happened when our maintenance folks installed the first one in my Husky, and forgot to put the battery heater back in. I didn't know that heater was gone, and ran all winter with it before I discovered there was no battery heat. Parked in Fort Yukon and Beaver with plane plugged in at very cold temps and always cranked well. Found out there was no battery heater and never bothered with them again on the Odyssey.

MTV



Not to side track from this thread, but there is a lot more to this story than I may have let on.... -25... poor little honda 2000 had about 10 gallons of 100ll run through her with no spark plug maintenance or a tank of snow machine gas in between..... wouldn't run for crap..... very cold soaked....battled it for the whole weekend....
BUT, when I flipped the the master I had positive oil temps and CHT temps that I was ok with, sorta. So maybe not really the batteries fault, but maybe more mine instead. And after a few tries, she fired, and took a hell of a good charge while climbing from the negative 5k++ density altitude up to the 7.5k area where it started to warm up some.
MTV I have no doubt your feet have been in those bunny boots before :D


More thread hijacking but, the Honda 2000 has a spark arrester screen in the muffler inlet that gets plugged with lead when you use lots of av gas in them. Pull the muffler and remove the screen or drive a punch through it and you will be back in business. For a while anyway, the valves will eventually stick as the tolerances are way to tight for lead. We try to run car gas in them mostly and then run them on 100ll the last tank of the season so they sit all winter without that ethanol crap gas in them.

It takes waaaaaay more than ten gal of 100LL to bother a Honda though, like three years of 16hrs a day for three months straight! I love those things!

Haven't got them back from paint yet. As soon as I do I take some pics and post them. Like Greg, mine are from Stene Aviation and are split cuffs.

Re: Let the 185 mods begin (again)

Flat floor extended baggage kit from Hitchcock Aviation just arrived. Wow, super nice product. Believe I have almost everything now for the first phase of the mods; firewall battery, flat baggage floor, 406 ELT. Decided to replace the two power plants and wingtip strobe/nav and tail strobe with AeroLEDs, need to get those ordered yet.

Just got off the phone with AeroLEDS, great folks. Ordered the Pulsar NS for the wingtips, and the Suntail Position/Strobe for the tail. Thanks for the nudge Greg. I'm jazzed by the way the electrical load on this bird is being slashed.

Unfortunately the country will notice a slight downturn in job numbers as I remove the two power plants in the back of the plane and fire all the people that work there. ;-)

Now the real work begins (on Monday).

Wow that is nice! I like it much better then the Selkirk one I have. Wish they covered the 182 with their STC.

Nice!

They are a bit more expensive than some of the other stuff out there, but when you factor in the weight savings, quality, brightness, and electrical load, they are well worth it.

They do cover 182s. Look at the airglas website. www.airglas.com

Re: Let the 185 mods begin (again)

Day 1 of this set of mods had us mostly taking stuff apart. You can see how much extra room I get by removing the factory Extended Baggage and Battery stuff in preparation for the flat floor. I'm guessing the Wagon lost around 45 pounds. 35 pounds for the battery, and another 10 pounds for the factory extended baggage parts, the two strobe power supplies, and the battery box, and the solenoids for the external power hook up. Also removed the Beacon/Strobe at the top of the tail. Not replacing it as the tail cone running light gets replaced with an AeroLED running light/strobe combo.

We also managed to get the firewall battery mount installed. Really nice unit, and I can remove the battery either out the top or out the front with Burl's kit. In my case access will be through the front. Also mounted the 406 ELT antenna today.

Hopefully tomorrow will see the completion of the firewall battery and extended baggage install, and if we are lucky the 406 will be installed.

Re: Let the 185 mods begin (again)

I have an early (pre-STC) Burl's firewall battery box. I figured the space between the battery & the firewall was for cooling, but now I see it's also provides clearance for the extra tube on the seaplane engine mount.

Re: Let the 185 mods begin (again)

No pics from today's work. Didn't get as far as I'd have liked but no real surprise there. We finished removing the old, separate, strobe and nav wiring from all three corners (quite a bundle) and replaced it with new, single, shielded four strand wire. We also pulled all the wiring that went to the old battery box area to operate things like the Battery/Master Contactor, the External Power Contactor, and the clock power wire. And we replaced all the rivets we drilled out to remove the factory extended baggage. In addition we mounted the new 406 ELT and installed the panel control switch. And replaced the old Starter Contactor with a new one (preventative maintenance - in my mind anyway), and that's when I realized I hadn't ordered a new Battery/Master Contactor. And I had to chase down a 90 degree Coax BNC adapter so I can run the 406 antenna wire straight thru the rear bulkhead without a loop. I'll get a picture of that tomorrow.

I'm very pleased with this round of mods, and pleased with my 185 as I dig into ever more nooks and crannies. Oh, just remembered I got the strut cuffs back from paint. Haven't installed them yet as I have the inspection covers open to pull wires. And speaking of that, since the airplane is mostly exposed already I opened the remaining inspection covers and we are going to knock out the Annual since it's due in a few months anyway. Saving some money.

Once you get her all done just let me know when you want to sell it. Husky is getting to be too small for the growing family :D

It's funny you say that cause before starting this latest set of mods if I wanted to I could sell her for more money then I had in her. But not anymore. Of course that's totally cool cause I'm having a blast.

BTW, you planning on coming to the Texas STOL Roundup in April?

Phil-

It is fun doing the refurb.... but lets keep it between ourselves;) Good idea on the BNC connector. I'm replacing my old ELT with an E-04 as well, might just do the same thing.

Gets expensive to do things correctly... but I would recommend you guys use a true 90 degree connector and not an adapter. I'd also upgrade to RG400 while you are "in there..."

Unless something unexpected comes up I'll be there again. Had a blast last year. Need to get out and do some practice...

The ACK that I'm installing comes with a 2" suppressor that is supposed to be connected between the antenna and the cable. I need a 90 degree adapter to put between the antenna and the suppressor. If not for the suppressor I'd have used the 90 cable end like the one in your link, better then an inline connector for sure.

Here's what the adapter and suppressor look like installed.

And here's the AeroLEDs that are replacing the running lights, strobe lights, and power packs - and the tray we removed that have the old strobe power packs that are no longer needed. Very cool.

Re: Let the 185 mods begin (again)

I too looked at that suppressor and groaned. I don't have electrics, so no sweat..... 8) That said, I wonder if you could install the suppressor on the ELT end of the antenna cable?? I'd call ACK and ask a tech.

Good idea Mike. Just got off the phone with them and they said it "has to go on the antenna for sure". Suggested I go to RadioShack to buy a 90 degree adapter (which is exactly where I got mine).
