Best wishes to the UK supporters for the upcoming races. Ineos vs LRPP in the LVC final was awesome to watch, and congrats on taking that out. I'm a kiwi, and supporting the home team (who are on the far side of the world....) but really looking forward to what should be be some excellent racing.

Your most unliked engine , petrol, glowor diesel.

I've got the same, and your description exactly describes my experience! -
Correct glass & resin to use please?
Dale Bradly replied to mightypeesh's topic in All Things Model Flying
The vast majority of commercially produced "fibreglass" products are polyester resin based product, because it's cheaper to produce for several reasons. The vast majority of commercially produced polyester resin based products have a wax added to the resin to aid the curing process. Needless to say, any subsequent processes don't want to stick to wax. So give the item a through clean with hot soapy water to remove any remaining wax. (And any other subsequent contaminants that have appeared since). And do this prior to any scuffing, or you just drive the wax into the scuffs, thus defeating the reason for scuffing it in the first place. -
I believe that putting the wheels on the ground is easy. The hard part of landing is about 300 ft or more out. The approach is what makes and breaks a landing. There is a reason many full-size aircraft perform some form of circuit. Ensure you are practicing and working on your approach. Be at the correct speed and height way out there. When that goes right, finals and touchdown just flow on from there.

SC Engines are back! .15 AP Hornet to 64cc 5 Cyl Radial.
Dale Bradly replied to Paul Marsh's topic in IC Engines
Aliexpress lists them as ASP. Interesting that the manufacturer keeping the seperate brands. I wonder if Magnum will also return. Aliexpress also has one of the Evolution styled models back. -

I saw these on Aliexpress last night, and thought it was too good to be true. Interesting JPerkins lists a .32, which i want, but Aliexpress doesn't. Hopefully soon! -

Yes!

What do you mean by "cheap"? Your definition and mine might be different. Some forms of heating are lower priced to install, but expensive to run per unit of thermal gain. Some forms are higher priced to install, and cheaper to run. There are some that are both expensive to install and run! I'm not aware of many that are both cheap to install and run when compared per unit of thermal gain ( or we'd all be using them everywhere!) Assuming you mean cheap to run; and the desire to leave going for days/weeks without babysitting: I'd recommend a tiny a/c unit, e.g 2.5kW. Clean, tidy, no smell, no invasive noise. Ive got no idea on pricing in your area though.

Prop is certainly not the factory standard supplied unit!

"Surprisingly, even after turning down the kilowatt output, the electric engine outperformed expectations, offering a 15% efficiency boost, partly due to the Beaver’s outdated propeller. Additionally, the MagniX engine’s lightweight design reduced the aircraft’s overall weight, contributing to improved aerodynamics after they were able to change out the nose of plane due to less cooling requirements. Holtz explains, “The efficiency of these engines is so poor 80% of the power is actually being rejected in heat and so you have to cool the engine quite significantly. So there’s a lot of that frontal area that is just allowing air to come in to cool the engine, which also slows down and creates drag on the aircraft. So being able to put a pointy nose on it, we got a significant improvement in the aerodynamic performance of the aircraft.” Source: https://engineeringmatters.reby.media/2023/09/01/electric-flight-takes-off/

One assumes that when you take out the 296kg radial, along with oil tanks, exhaust pipes, fluids etc and replace it with a 185kg electric motor, compromises must be made. That compromise could involve 100+kg of lead, or...

Differential thrust with Spectrum DX7 (gen 1)

Certainly can be with the JR, cause I've done it. Don't remember how though sorry! -
So called " Driving aids" on new cars , help or hinderence ?
Dale Bradly replied to Engine Doctor's topic in Chit-chat
VAuto dipping headlights. Second best thing ever. Why? 1. I'm human. I forget. I miss switching correctly from time to time. I'm also lazy. So its one less thing i have to do in life. 2. Because I'm human, and not 100.00% reliable at all hours of every day, as opposed to the camera smarts (or whatever it is that my vehicle is using) that doesnt get tired, doesnt have off days, doesnt "just forget", other drivers are not blinded by my faults. Therefore this has to be a win for the tech, because the other road users are the principal benefactors, not me. -

Dale Bradly replied to Engine Doctor's topic in Chit-chat
I love this feature. Why? Because I'm lazy. (And honest). I don't have to touch the thing: I stop, the car puts it on automatically. I drive off, the car takes it off automatically. What's not to like?
