Running engines in the cold

In case you don't already know, in severe cold, Cox engines may not hold enough heat to run well in flight. Some of our cold country members wrap yarn in the cooling fins of the head and it apparently makes them hold a needle setting and run much better.

I never thought about wrapping string around the fins to hold heat, but it makes sense. I do know that 0.020's are fussy to keep running on low nitro fuel even in the summer.

But I used to run my Fox 0.09 on an airsled in the winter with no problem.

Maybe because of the increased displacement?

Jim, depending on your location.. Good 1/2A fuel is available for your .020's now, through "Hobbico" carrying the "Cox Super-Fuel" label. It was re-formulated with the correct castor-oil ratio recently, with help from Dave Sproul (Product Mgr. at Hobbico).. and has been officially tested here, by members of this forum. The fuel is currently available through Tower Hobbies in 25% nitro quarts. Hobbico is also offering the fuel in 35% nitro.. but I'm not sure if Tower stocks the 35% yet. The annual CEF "Tach Race" was recently run; using the new "Cox Super-Fuel" which was donated by Hobbico.

Here's some info on how Dave Sproul and Hobbico "stepped up to the plate" on the fuel's re-formulation.

https://www.coxengineforum.com/t7143-cox-super-power-fuel#89717

and the "Tach-Race" thread that covers the fuel's performance.

Glad you know where the boy is.. Does your new camera have a phone? Laughing

http://imaging.nikon.com/lineup/coolpix/l/l30/spec.htm

That's a nice little camera! Easy upload of pix to your computer with the USB connection/cable.

Last Monday, my brother Jeff needed a snowblower for cutting a trail through the woods.. to his cabin. I offered my old 1968 Allis/Simplicity. We loaded it and the gas jug into the back of his pick-up and headed over to his cabin, about 3mi. from my house.. and set-back into the woods about 50 yards. The cabin has electricity and a wood stove.

(that's my brother, back there on the left)



If you look down the trail.. you can see a catwalk the he built, where a brook flows in the springtime. It zig-zags for a run of about 40 ft. and is about 2" narrower than the rear axle on my machine.


No tire chains.. The L/H wheel-hub disengages manually for ease of steering if needed.


Check out the 2nd-stage paddle-wheel type impellor on this "old girl"..


Here's the cabin right after he built it; late summer 2013. (sorry about the sideways pic)  Huh...


It's currently snowing at home here in N. Smithfield, RI.. and the forecast is 3-6" (4-8" in Providence)

Hey Bob, It stayed below freezing here last night. We woke to 4-6" of fresh powder this morning. I brushed both cars off and warmed them up to find that the "blower" is not working in my Chevy Trailblazer again. DAMMIT! DAMMIT! DAMMIT! DAMMIT! DAMMIT!

This blower problem originally exhibited an intermittent condition "once".. about 2 weeks before finally stopping altogether. The resistor that I replaced is a common failure-part. Now I think that there's a bad connection somewhere between the switch and the resistor.

Yes but it is a DRY heat....grinn


seriously some years back I was golfing on Fort Huachuka at 103F and 3% humidity, very comfortable compared to Fort Hood at 98F and 65% humidity

I was also amazed at how quick I adapted to 121F in Iraq but admit I never got used to drinking gallons of water a day

AZ Phoenix at 116F is still gonna be uncomfortable even in the shade

I was in Seattle two months ago and drank the amount of water I'm accustomed to in Phoenix. I've never peed so much in my life.

I used to do a lot of work in PNG and Irian Jaya.  High up in the Owen Stanleys the temp never goes above about 25°C - day or night.  However, the humidity never gets down to 99%, 99.7% being a typical day.  Many of the villages we operated in received >300" rainfall per anum.  Working in those conditions is so draining, and one constantly feels as though one is dying of heat exhaustion.  

Being from West Oz, and being well used to temps well above 40°C, I can assure you that the major factor in "feeling the heat" is humidity, NOT the actual temperature.  Summer humidities in most of WA seldom reach 50% and are usually below 30%.  Up in the Pilbara they'll have 3 or 4 months each year above 40°C, but the humidity will be about or below 10%.  When I was working up there it was far more bearable than in PNG.  One must, however, drinks gallons of water.  I drank about 10 litres just during each work day.

One memorable mid-summer day, in western NSW, I was involved in "grunt shuttles" (shuttling soldiers into a "war zone" for a military exercise - I used to fly Caribous) requiring to stay below radar (<100' AGL).  We did 7 x 100nm shuttles, op stops at each end and with the cockpit temperature up 57°C in the middle of the day.  I think all 200+ grunts chundered on the cabin floor that day - it was almost ankle deep!  At the end of the day we jacked up the aircraft nose, opened the under-(cockpit)floor escape hatch, called for a fire truck and hosed it out.  Man-O-man!! What a day!  Any'ow, the point was that 57°C is the hottest temp I've ever had to work in.  I did experience a -ve (celsius) temp a couple of times in Canberra.

Dinsdale. I'm sure they probably worked out what you were talking about, but for the sake of the uninitiated, you may want to interpret "chunder". Gee we talk about some great stuff on here lol!

According Bazza McKenzie, a reputable bloke if ever there was one, on the old sailing ships transporting convicts to Oz, when one felt nauseous one would run to the side of whatever deck one was on and shout out, "Watch under".  This warned those on lower decks that someone was about to spew/vomit/have a charlie chuckle/do a technicolor yawn over the rail, and to watch out below.  "Watch under" was soon abbreviated to just "Chunder", which is now the standard Ozzie noun or verb referring to vomit.

Look for movies:  "The Adventures of Barry McKenzie" 1962  and also "Bazza McKenzie Holds His Own" 1964 and also "Bazza Pulls it Off" 1971

I think I'd like AZ. New England is nice if you like roller-coaster climate change.. but I find myself now; liking warm weather much more than cold. This past Winter's blizzard was epic in my region. The most beautiful climate I've ever experienced.. was when I spent a week in Aruba. Dry heat (avg. mid 80's F) with a constant southwesterly breeze.. all the time. It's almost guaranteed. There's very little rainfall.. and only rained once (for about 2 minutes)during my stay.

Jim, I imagine your climate to be similar to George's over in Clovis, NM.. but he mentions it being constantly breezy where he is. Too breezy for small flying-models.
