MT. Hood summit try?

Well, I am thinking about flying to the summit of Mt. Hood in September. I want to know if anyone has any knowledge of flight patterns around this mountain. The plan is to start from Timberline Lodge and fly right up Palmer Glacier to the top. I would stay about 500 feet of the mountain to avoid any aircraft of the full size nature. The distance from the top parking lot is about 1 mile to the summit. I have a 400 mw and 1 watt 1.2 vTx I am thinking I should use the 1 watt but never had trouble the 400.

How does the snowy\rocky terrain effect signal? The top is around 11,00 feet

Good idea to do or not??

No OSD, just good antenna and receiver. Want to keep it simple to avoid any conflicts.

Well crap. I miss calculated the distance from the parking lot to the top. Looks to be about 3 miles! This might be a deal breaker. I have never gone more than a mile.

Have you done practice runs with your airframe climbing it up at the same MSL?
Also I would tell ski patrol that you're gonna fly up the mountain, sometimes
they have random rescue choppers flying about up there. But the above is
reason enough to say don't do it yet and get more experience before you try.

yeah, 3 is a bit too much right now. I have a diversity setup with 8dbi patches but I think I might need more power since the rate of climb would be pretty steep.

The biggest drain is from the elevation gain.
Parking lot is roughly 5900 ft, summit is 11,200ft, so 5300 ft climb, and 3.2 miles out.
I know my Foamaroo will do that on a single 5000mAh battery (both range and altitude)
but not much left at the end. With well tuned video antennas, should be able
to do that at 400mW and about 8dB of gain on the Rx side fairly easily.

Probably need to change the prop for higher altitude.

I was thinking about using a .60 size low wing trainer with a 5800 mah battery setup and 1 15x8 prop. I could use my easy star but I am not sure I could fit more than 3000mah into it. Your right though, the climb rate is going to kill it I think. It would be really cool to get that on my gopro! Does the terrain above the tree line affect radio and video transmissions? Does it reflect off of the snow?

Thanks guys!!

That's a good tip!

I have gone almost 3 miles with omnis on 300mw, you should be just fine with patches on 1 watt.

If you have more battery and you want a better place to fly I would reccomend flying from here. It is deserted overflow parking lot lower down on the mountain that is really close to a boy scout lodge that my ski team rents for summer training. It has excellent line of site all the way up the mountain and you don't have to deal trying to fly with a full parking lot of people.

I wish you the best of luck, I plan to fly there also next june when I am out there

but definitely do a flight at those altitudes and distances first before you do it on the mountain.

Definetly a no-go, they would be sooo confused, the ski patrol there, from my experience is not organized and they have quite silly rules. They wouldn't know what to do if a guy showed up saying he was going to fly over the the mountain.

Besides, Mt Hood isn't like the European glaciers I have skied on, they don't have supply and rescue choppers coming and going because you can ski or snowmobile down to the parking lot, instead of having to take 2 trams and an underground train. I have only seen one airplane come close to Mt hood and that was a Carbon Cub that was about 1000 Agl above the mountain.

Thanks for the tip!! If you do come this way to fly, let me know!!! I ski every weeknd in the winter at Meadows. Sometimes on Palmer in the summer.

I will check out that place you suggested and start testing this weekend!

ezstar will get 3 miles out and 6000 feet up no problem if there is no wind

with a 3600 mah 3 cell


If the plane has a large heavy battery the climb rate really is effected.

go light and climb fast or straight to your target.

even the ezstar can glide back home with that elevaton gain

I fly mountains lots and climb like you plan all the time

the winds are what really will mess you.

video is just fine as long as you have line of sight

becarefull of the esc and motor specs if you climb at a fast rate

but rather do some circles as you get up the mountain

or better yet go on a day when there are mushroom clouds to get you up hter.

add power to help you get up even fast inside the cloud
