Even trying to bring it back to correct alignment with the trimming on the DX7 was nowhere near enough so I had to get some pliers out and squeeze the liitle "U" shape bend in the elevator push rod, which then tore the horn out of the Elevator and made the push rod look like it was out of alignment - bending upwards...
The Horns on the Elevator don't need much for them to tear out, watch out!
It was all a bit of a mess but after a bit of patience and concentration my Ember is re-trimmed, the Elevator horn is glued in and its sitting waiting for someone to take it for a buzz - me!!

Any ideas on uploading pics, still having trouble

I think the tailfeathers are a weak spot on the Ember. I'm on my second replacement set. I tried making them out of thin foam plate, but they wound up heavier.
On my current set I put strips of tape top and bottom spanwise across the horizontal stabilizer just before the elevator hinge.
I also put tape top and bottom on the elevator in the area where it's shorter chord for elevator clearance, to serve as a kind of "torque box".
This stiffens things up quite a bit, though it still adds a bit of weight.
If I were to do it again, for the strip in front of the hinge, I'd probably use tape strips only a quarter-inch wide instead of the half-inch I have now.

Hey everybody I just found these.....I have been browsing through the vapor and ember threads and didn't see any mention so I thought I would post the link. I have sent and email asking weight. If I do not get a reply on moday the latest I will call.

I've now had a few chances to fly with the fences and slats, and all I can say is WOW. What a difference they make. I've only been flying a few weeks after 30 years away, and I'm flying 50' x 100' laps around the back yard. I like that it's easy to remove if I'm going to the big field down the street.

Congrats with the mods. I am thinking of doing something similar to my Ember #1. Feel free to post some photos.

I am envious of your being able to fly outside as it will take me several weeks to dig out of the snow in Ohio. Happy to hear that you also enjoy the Ember mods.

Here is another old thread on other things to do with the Ember wing.
For your enjoyment!

Ember Bi-Elavator Feather and 3.7 250mha Mod

Hey all,
I cut and sanded back a paper thhin piece of 1mm balsa out about a third of the size of the Normal Ember Elevator and made a similar version only with more of a point to the leading edge, it weighed just under .3 of a gram. I fixed it an inch above the current Elevator on to the tail feather an inch in front of the rudder hinge..

I found it flew the same speed still did tight loops
BUT when you take it up and kill the throttle it descends down three times the rate of the stock standard setup and it loses altitude at a much lower rate when flying in general also, so my landings now I can come in with zero throttle from a lot further away and still maintain height and speed.

With the added weight I thought I would have needed to give the elevator some up trim but I didn't need to so it is now its a permanent mod that is glued on and I love it..

I also got a home made 3.7v 250mha and placed it under the brick with two tiny strips of Velcro, I got slightly more power and a flight time well over 18 mins as that is what I set my timer in my DX7 to...
It did slightly change the flight characteristics but nothing major to report about, it still went at what looked like its normal speed so I bought two of them from the guy at my indoor club...

I bought a Parkzone Ultra Piper and took that forts maiden flight all I can say it fast and very nice to watch, will report back on that purchase another time

Is anyone here from Perth in Western Australia, just curious..
I cant explain why I got such good results in Aeronautical terms or in RC lingo but the proof was in the flight testing I guess...

Has anyone else had problems with the battery staying in place? I changed out the velcro yet the battery still keeps dropping out during flight. Ugh. Any advise would be appreciated.

No respect, no respect at all !!

OK, so we had a nice snowfall last night. Was actually tempted to fly Ember 2 #1 in it, but had no one around to photo document the attempt. This morning, it was a beautiful sight, 3" of fresh snow. So, I sent out two of the Embers to check out the flying conditions and the landing strip status while I tended to some other RC affairs. I come back out on the control tower deck to find out how things are. Do I get a report on the flying and landing strip conditions (hard pack?, granular?, loose & fluffy?)?

Nooooo......these two turkeys had other ideas in mind. I treat my Embers very well, thank you. Nice warm and individual hangars, fresh batteries, snazzy lights. All I asked for was a flight report.

I tell 'ya folks, no respect, no respect at all!!

As I fly using the lightmax 3.7v 138mha, they dont come with velcro and the parkzone velcro is far from satisfactory so I just ripped out the old fluffy piece from the Ember and my Piper Cub, bought a foot of thin velcro and cut it to size, now nothing goes anywhere even lager batteries that weigh more thanthe originals stay in place - so for $5 dollars you will have you problem fixed - NEW VELCRO!!!

Don't forget to peel of the old velcro from your original batt and repalce that too!! You can always use something like hinge tape or even your standard office celo tape each flight, or a rubber band...

Happy Flying!!!

I love my Ember2.
But I want it to perform like my GWS slow stik with an E-flight 370

Well I would just like it to fly fast enough to do a loop from level flight.....
Has anyone tried to hot rod one?

I have a Vapor a Suhhoi a Mustang a MCX and a Blade CX2 so dont just recommend another plane.

I'm thinking about putting a Suhkoi motor / prop on it but am not sure if the ESC for the vapor is rated for it.
Would love to save time and money from someone that has already figured this out...... any help would be appreciated.

You apparently already have enough fast flying planes, so why in the world would you want a plane that's designed to fly slow fly fast? Why did you buy it in the first place? If you love it, why change it?

Try something like this.

You'll keep you same thrust line. This is a Vapor gearbox with a 5530CF prop and the RX ran flawless, and the power increase was outstanding. I would think a twin Ember gearbox would be fine with a 4030 CFprop or a stock prop. But don't quote me on that. I don't think the add. weight is going to affect the plane that much.

You should see my Vapor some think it's total overkill I think it's totally awsome. The twin gearbox I just modified one a little wrapped them together with thread and CAed them together making sure I had good gear meshing. It was fairly simple. I gave it away or I would post better pics.
