Default Just picked up an eflite ascent 450 glider-SWEET!

This is a pnp aka plug and play version as it has everything installed in it but the radio system and battery.
It says it takes 2-3 hours to put together but i had it done in just under 1 hr and ready to do its maiden.
I must say thats it was pricey at 179 but it is very very well built and very tight all the way around.
So as i sit here just dreaming of my first flight w/it i thought since i cant go out a fly it right now as we have a front coming in here in charlotte so therefore we are having some steady 10mph winds gusting to 20 thought that i would post this here and ask if anyone here has 1 or has flown one and what their experience was/is and if there is anything i should take notice of.

Anyway here is the one i bought> http://www.hobbyzone.com/rc-planes-e...shless-pnp.htm

Oh and i did a test of it to make sure evreything was good and i fired up the motor and must say this sucker has some extreme pull to it, feels like it could drag a few pounds of weight accross the floor

congrats she does look sweeeeeeet.this may be a dumb question but is there any advantage to the wings being angled up atthe tips like the ascent rather than a straight wing?good luck with your maiden

Default Different Dihedral?

Hello Crabby, Welcome to Wattflyer!
I'll take a shot at answering your question about the angled wingtips;
That type of dihedral is called "Polyhedral" (More than one dihedral break) and is commonly used on rudder-controlled gliders, as well as Free Flight gliders.
Having the dihedral breaks outboard results in a single, continuous center section, which is generally stronger than a center that has been built in two pieces and joined (with dihedral). It is also usually lighter than a wing having center dihedral braces, gussets, etc. The main vertical aerodynamic stresses on a wing are transmitted to the center.
A wing develops the most lift when it is flat, no dihedral. But for stability purposes, we add dihedral, which reduces the overall lift on the upturned portion of the wing. A wing like the Ascent provides the best of both worlds. About 2/3rds of the wing is flat, but the upturned tips (technically, "Tip Dihedral" but also called polyhedral) provide the necessary stability.
Normally, when you see a wing with no dihedral, the model is controlled by ailerons as well as elevator and (possibly) rudder. Ailerons allow the model to roll or bank, exactly the type of attitude that dihedral resists.
There's quite a bit more to this aerodynamic stability theory, but I've tried to touch on the major parts. Hope it helps!

Yur not takin over the thread at all np

Anyway it took her out and wow, i think the motor is overkill bigtime as she will downright haul booty for sure almost to the point that if you dont watch it you will lose it quick as she doesnt like to fly slow so you have to keep the speed up unless yur cathcin thermals.

As i siad the motor is almost overkill as she will hover fine at half throttle and not even strain.
She will pull straight up so fast she will dissappear if you dont watch it.

I bet if she didnt have the dihedral wings i could slap on ailerons and she would do 3d :p

Default Ascent 450

Man, What a price jump. I got mine Aug 12 for $184.99. Now the Horizon web site is listing it for $239.99. I really like mine but would have thought about it a long time before paying that for a small glider. I have had no problems with it and have flown it nearly every day since I got it. It goes up like a rocket and glides faster than my other gliders.

One of our club members just purchased one of these. A couple have the original ARF and it was a great glider/park flyer.

The new Receiver Ready/PNP model seems to have a design flaw. The ESC does not have a brake. That means the prop will freewheel and not fold. This absolutely kills the glide.

My friend has had to go out to buy an ESC that has a break.

I consider this a MAJOR packaging flaw by the MFG. My friend called and they told him that the ESC does not have a brake.

Bad news.

Mine has a brake and it works every time. There was a separate set of instructions included for the speed control. The ESC is blue as pictured at the Horizon web site

Henry,

Can you post the procedure for setting the Brake? My friend did not receive those instructions and when he called Horizon they said the ESC did not have a brake. This is great news.

Looks like it is pre-programed and can not be changed .

Thanks. The ESC in Mikes will not brake and will not fold the prop.

I don't recall. I will send him a link to this thread and ask him to jump in.

So, when you are in the air, and you bring the throttle to zero, it stops the prop from turning and the blades fold reliably, right?

Every time without fail. These do not fold.

OK, your response totally confuses me.

First you say Every time without fail. - I assumed that you mean the blades stop and fold.

Then you say they do not fold.

Which is it?

Sorry about that. The blades on the Ascent 450 fold every time without fail. The blades on the other gliders in the picture do not fold.

Henry,

You have been a huge help. Thanks so much.

As long as it is supposed to be on, it would seem he has a defective ESC. I will tell him to call in for warranty support.

Default Ascent 450

I purchased one about three weeks ago. I maidened it a couple of days ago, first with about three hand toss launches with no power and later a flight with about one quarter throttle. I was very surprised upon hand launch at how far the Ascent was able to glide. I have had two meter electrics in the past and for a small plane it was very impressive. When it was launched with power(quarter throttle mind you), it really wanted to gain altitude, but I really didn't want to take it up too high because visibility/light was running out. I was running out of light so I quit for now, but walked away very satisfied. I can't wait until I get some more time to really fly this plane and really gain some altitude so I can try and get it trimmed perfectly. Just my two cents. Tom

Are folks still having fun with their Ascent 450 BL's? Mine has been built & bench tested for awhile but I have yet to maiden, wanted to start with the ParkZone Radian. The build went well and I have the recommended e-flite battery, and ar6100, just waiting on a calm day & nerve to maiden. I did check the ESC programming and the brake works - so I think I'm all set for maiden just check CG & whatnot.

Very interested in your feedback on Ascent vs Radian. I am looking at one or the other but cannot afford both.
