Food for thought, despite super strict rules in the USA as regards flying. https://www.yahoo.com/news/one-just-two-cl-415-050932342.html

Great job I love this.

Thanks I saw your heater when I popped around the other week. The issue I have is the only access into a ram packed garage is through the big front door. The side door is blocked off with junk that needs clearing out. I have a fan heater there & also a dehumidifier. If I got in & closed the door, the fan heater would bring the temp up quick enough. When I was engine building & kit car building that's what I did. I now have enough jobs building up that I may camp out in there and crack on with them. Hopefully before our next indoor session. My brother lives on a narrow boat full time & has one of these diesel heaters. It runs off his main diesel tank, I think he runs on red as well. It's generally pretty reliable but he does have a wood burner & back boiler for when it misbehaves.

Our club fly indoors for the winter & I'm getting too damn old for A. building in a freezing cold garage & B. flying outside in this weather. So ordered a TY300 indoor model from Aliexpress. In fact two. I also order a tiny DSMX Rx from them at the same time. The RX is about 1/2 your thumbnail size! Well the receiver has arrived with only an aerial wire. There are 4 tiny pads that need RX Pos & Neg & motor wire pos & neg wired to. Each pad is around 1mm square. Bearing in mind I was trained as an electronics engineer & in 1973 the first 6 weeks of my Apprenticeship at RAE Farnborough was soldering lessons & practice. I've just bought an illuminated viewer from 7 day shop that fits over your glasses but still not looking forward to wiring this thing up. Wish me well!

Electric/Electronic Experiment Kit for 9 year old
Jim Hearnden 1 replied to PatMc's topic in Chit-chat
The Phillips kit brings back memories. I had one of those at around 11 years old. It lead to a deep interest in electronics & my becoming an Electronic apprentice at RAE Farnborough. The apprenticeship was 73-77 and I have been in IT since 79! Now 67 and still working in IT. -
Winterflying gloves, what do you use?

These look good, may treat myself to a pair:- https://victorylanesport.com/products/vl™-outdoor-heated-gloves-windproof-and-waterproof-with-plus-velvet?utm_source=facebookads&utm_medium=02heated_lssz_1111&utm_campaign=02_heated_lssz_1111b&utm_content=122179412954122322&campaign_id=120215116129090454&ad_id=120215116188380454&utm_id=120215116129090454&utm_term=120215116188360454&fbclid=IwY2xjawG7r0dleHRuA2FlbQIxMQABHVzFOEFdtF3n6rIxQbB9nSCVlTCescDLqDC0vFUfHnscFHa3yCUbVTA6mA_aem_XEh5Tei2L1bzb5UjpTfTZw -
AVGAS these days can either be 100Low Lead (LL) OR 91 U/L there is pressure from the Greenies to move towards 91U/L BUT not all engines are approved for it & a Lycoming or Continental is now £30K plus for an engine so people are naturally twitchy. However some of the newer technology engines (Jabiru & Rotax to name 2) are specified to be run on unleaded as the lead contaminates the oil. But even more important on the Rotax two strokes they find they get short plug life as they get lead contaminated with 100LL. Hence a lot of people running MOGAS (Car pump fuel) but that has hassle with evaporation, water & ethanol content etc.
-
Thinking on this, if you have an airfield local to you then go buy some u/l 91. This is unleaded petrol, made & distributed to strict aviation standards. Definitely no Ethanol. BP say:- Our unleaded Avgas grade UL91 is a dedicated aviation fuel providing an alternative to Mogas. Compared to Mogas, UL91 has an assured energy content with no alcohols or ethers which may reduce aircraft range. UL91 has a fixed volatility range and is designed to work year-round without seasonal variations.

Just to clarify terminology here, higher octane isn't more powerful. Octane rating is anti-knock. Even with 4 stroke petrol engines you'll never get a high enough compression ratio to get knock or pre-ignition. But it does have less ethanol content.

Just checked, because my metal bashing are long ago. 7075 melting point is 475 Deg C.
