Going Tropicalize

Guys whats your take? I was re evaluating on methods on making an aircraft tropicalize . meaning able to able stand up and function normally in High temperatures and humidity.

its now summer in Philippines. 102F / 38C Max UV Index: 10

Hi temps = poor performance,
add 15-25% more power than normal and it should be ok.
I didn't experience too much problem in Baguio City, higher altitude and Hi Temps.

Lots of ventilation, and actual air flow directed over the critical components. Figure out how to run an aluminum fin from the ESC to the outside of the plane. Etc, etc. but Marty's right high ambient temps are gonna make life difficult. Much better when it's 0 degrees F and flying a full fuse. First few minutes are a bit sluggish, but once the lipo warms up inside the foam fuse, flying is just about perfect (until the fingers start to sting!)

Keeping the components relatively unstressed will be a good start.
If you have a motor and prop combination that runs hot in normal conditions it will cook in hot conditions.
Use on oversize ESC and position it where it receives full airflow.

as much I like to keep my electronics inside the plane to keep them protected from the elements it seems will have to have parts of it expose. just to keep em cool. will see if I can keep the ESC inside but the heat sink fins outside. like a radiator.

interestingly Marty's encounter could be much more at high temperature and high altitude. I fly closer to sea level.

interesting Funjets and EDFs would have to exert more power . might have to reduce to gliders to be more conservative.

any ideas if its possible to build an all around plane that can take on extremes Heat and Cold , Dry and Humid

Build something light with a generous wing area that will fly well at about half throttle.
Allow for plenty of airflow past he motor and ESC.
Fly classic aerobatics and avoid long hovering flight. Fly on the wing, not the prop.
A powered glider would be a great answer to the heat problem.
A 10 second power run takes you to thermal height and then you float about for as long as you can find lift.
My gliders land with the motor and ESC at ambient temperature.

Just heard from some of our RC guys that will be flying in winds of 15 to 18 knots.
basically hot blowing Air , seems to be an extreme endurance challenge. How you Aussies Do it??

I like to fly the Dawn Patrol .
Usually it's calm and the planes look pretty in the air as the low sun lights up the colors.
Spend a couple of hours at the field and then come home for breakfast... Lovely!
I live in a part of Oz that is noted for its nice climate, so I seldom have to endure extremes of heat or cold. I do have to take care not to sunburn my face when flying the gliders, however.

Today we turn up the Heat... and push the limits of the Aircraft's electronics. several of us challenge the elements.. the electric and foamies took alot of beatings in these conditions. the added challenge we do this 12nn-3pm

in winds gust 8mph-10mph

Temp 85F to 92F

Humidity of 42%-52%

UV Index 10- 11

two things could have happen ether one of the Aircraft's components conk out or the RC pilot pass out of the heat.


Speedactyl PX22-A is just 36inch in wing span but on an runway Length over 2km, why not?

5 degrees warmer than it was here.
But I didn't choose to fly during the hottest time of the day.
With age cometh wisdom.

yup. its a mix meyhem of different aircrafts in the area
this way we can test powerplant and materials. and at these winds speeds. small rc aircraft is not possible. I think the next challenge is typhoon season.?

good thing. nobody pass out of the heat.

What airport are you flying at? they kicked us out of the Bagio City airport, the morning joggers protested and won. Always thought airports were for airplanes, not joggers.
