Hey Sean,
the three minutes I was talking about was with the Ramtec Fan that Doc has(read a few post back)... those have a higher pitch and are pulling LOTS-0-AMPS (120amps)
I think the Dyn-e-max would do fine with the Scropion 630 kv out runner(95 amps)...

Stu's and Tams are still going to be the best setup..... were talking pounds of fans, esc , a batt. lighter.

Sean... there is a new sweet sounding TJ-100 with the seven blade stator..add a soft mount and at these low power levels per fan it will sound great too...

The biggest problem with EDF is flight time right now... so make it light and you will extened it... it makes a 3:30 flight go to 5:30 for me that's a huge differance, like night and day
3:30 is not acceptable in my book it must at least do 5:00 or I don't want it

Hey 33, since my heritage is British, I'll help ya! I built a MIBO and it looks like you have some of the same unknown parts. It took me a long time to figure it out. Some of those things you are showing are hinges and stands offs for the slats. Look like they got the wing all very wrong though. You can mail me at [email protected] if need be, bet I can save you some headaches! Don. PS, you can go to jetadic.com and see my A-10 sitting on top of the wing of a full scale!

Sean,
It my opinion too it sound better than your.....
But you don't like that and reported me.
That O.K.
You can't play with big boy...you go cry.....[sm=cry_smile.gif]

Hi,

Uhh.....no, I didn't report anyone for anything. Get your facts straight. Oh....wait....FACTS. Sorry, I forgot. BTW, I'm laughing out loud at your referring to yourself as a "Big Boy".....[X(]


Now, back to A-10s?

O.K. Sean
No more playing.
Now get back on the A-10.
So you go to do one or just talk?
If so when?
I like to see you fly something before I get really old.[sm=lol.gif]

That what I figure......
Is all talk.
You never go to do one. But love to stick your neck in when ever Tam is in it.

C'mon guys put your toys back in your prams and get back to the subject matter, before someone reports you both for personnal attacks.

Mike

Sic has not recieved the slats or the standoffs for them yet. What you see in the pictures is just part of all the parts that still need to be shipped to him. I will be sending all the remaining detail parts out to him when i finish up the pylon molds. I am also finishing up some other molds like the ones below of the door detail which i had to fix because the flange was on the edge of being almost to small. They will be easier to trim and fit now that the flange is larger. I worked on these tonight. I also have a few other vacuum form molds like the dispencers on the wingtips and a few other things that i would like to get finished before shipping. Its been hard to finish these up juggling making kits and finishing molds and cad design. I like detail but in real life the A10 has a ton of it compared to other planes.

I like your a10. I remember seeing it on that site a few times. Is that a museum where you taken the pics?
chris

Ok, where were we? Sorry if it seems like i am jumping around on the build. I am the type of person that prefers not to read instructions. It takes too long. Besides, some of you might want to start out with something different. I am keeping your options open.

After you are hinged, here are a few pics that may help you with control horn placement. On all surfaces, the control horns will be glued with thick CA to the outer skin where control horn flange is, glued up against ply former aft leading edges and glued to the inner opposing side surface. The neck of the control horns will need to be trimmed up until they hit the opposing side and the horn flange sits flat on the outer surface. The aileron, outer flap and rudders are tapered so you will need to trim and fit. The inner flap and elevator are constant , so you can just put the horn on the side and mark where it needs to be trimmed. As you can see, i marked the elevator horn and it needs alot of trimming. One of these days i will change the cut file to where these will not need to be trimmed but the suffering must continue until i get the time. On the other hand, the flaps do not have the ply structure in this area. They have carbon fiber running through these areas instead but will be glued in the same fashion. Ofcourse you will need to drill your hole for the clevis.

I am not sure what john sent out with his kits but the larger robart hinges are what we used on all the surfaces and i will be sending these out with the kits i am selling.

Ron,
They were purchased (RamTec) from a dealer, they aren't knock-offs. One of them is unassembled, while the other was assembled with the Skorpion installed, and balanced by a guy in California who does this sort of thing. My firend bought them and has offered them to me to use in the A-10, but the more I look at it, it looks like it would not be a good combination, I'll use it in something else. The 6S setup that Tam will be doing might be a much better compromise. I am all about keeping it lighter. As far as sound goes, the real A-10 has a whine that to me sound almost like an electric, so as long as they are "blowing" I will be happy.
I'm in no big rush, so I will get with Tam when he gets back to work and discuss his recommendations as well.

The Stumax does sound the best but its backwards and that would be very apperant in the A10. The tam doesnt have enough blades to look right either. I would try and put something in thier with more blades or it just wont look right. I am all for keeping the weight down but its a scale aircraft and you dont want to kill the looks of it.

Gunradd,
I did think of that with the stu max that it might not look right...
I think Tams will look fine with four blads and a 7 blade stator... not as good as the Dyn-e-Max
but I guess it comes down to how important scale is going to be over performance... or a balance of both

I'd at least wait to see what Tam comes up with in a few weeks then base your decison on that
gives you an option and options are always good

Only thing about the stator is its behind the rotor so you would only see it from behind. The dynEmax I think would be sweet but its pretty big. EVF would look and sound good but they arent cheap. Tams for the money would be the best deal. For scale looks and sound I would go dynEmax or EVF. The EVF 4010 is not much more than the stumax when you include the price of the ESC and is very effeicent on 10S.

The only way to get an A10 to sound and look right is to put two turbines in it easy rearly.

Mike

He might not have a place to fly turbines like I dont. Not to mention I get sick and tired of smelling like jetA and hearing turbines at work and do not care to hear them on the weekend I am deaf enough already lol. And an electric fan would look better than most of the turbines in the nacell if it has enough blades on the rotor.

Is kind of funny.
When we making fan never think about sound. We thinking about how to get the best performance. How to fly big model on least amount of power. Electric always had been short flight time or over amps the system and hard on equipment shorting the live time on the fan system.
Our goal had accomplish. We had flew from the smallest aircraft up to the biggest BVM Mig-15, Skymast F-86, BVM Bandit and the lists can goes on. You guys get the idea. If you do the search on all this aircraft. Which fan is flying it?
The only negative comment they can said about TJ100 is sound......but not even one of those nice sound fan can fly any of this model with decent 4-6 minutes flight time on less expensive batteries pack like our fan are using.
Fan is about effecient. Yes, sound would be nice.
That what we do next. By offer 7 blade stators for twin projects to change frequency of the sound. But not give up the performance.
I'm sorry for those doen't like the sound. There is many fan with nice sound out there. You can buy one and go do the project you like.
Show us videos that you had good success. I like see them or other like to see them and decided what to buy.

Here is the F-18 video.
This aircraft weight 25 lbs.
It only use 3.4kw per fan and it was very effecient. This is stock 5 blade stator. The 7 blade stator sound even much quiet.

If you look some part of the video with about 1/2 throttle.
That what is sound like in the A-10 using that low power set up.

I think the Dyn-E-Max would look more like a real A-10 than a little P-60 sitting in the pod

paint the white corkscrew on the spinner and it would look dead on

There just about no where within an 1 1/2 hour drive to fly a turbine... for me
I hate the smell of kero and wouldn't want to spend $5000 on two motors

I'm an electro kind of guy can't you tell ...it just to user friendly

I think turbines are cool...just not for me.. I like to watch them and fly with them but that's about it
I love electric because you really have to think about it to make it work right... and there just getting better and better

True,

Some fans sound pretty close, too! The Stumax, Dyn-E-Max and some others have a convincing noise, so you don't necessarily need two turbines in there. That would be quite cool, though...

edit: removed personal attack

Tam,
That video is certainly impressive, and I don't think it sounds to far off from the A-10, it has a distinctive whine, but it has a ton of "get up and go", that F-18 looked very impressive on the fast fly by.
How much flight time are you getting on the 10S packs, and what type of batteries are they?

Very True Sean
I was flying my Stu Max powered Spark yesterday and some of the guys thought I had a turbine in ..until they asked
the performance and sound are just outstanding .. and make me want to sell all my noisey EDF's

don't want to get Chris's good thread off track... back to the A-10

The pack are XPS 5s x 4.
This pack cost around $140 each.
The flight time can easy done 5 to 6 minutes with throttle management.
There is Hyperion 5500mAh 35C is available. That will give you another .45 second.


For this A-10.
The 6s system is doing 82A.
With 5000mAh. With good throttle management you can get up to 6 minutes plus. If it fly so light.
There 5500mAH or do 3300mAh 2P 6600mAh.
Those pack you can get pretty cheap this day. Now you looking easy doing 7 minutes.

Shaun,
Sorry miss spell your name. I was thinking of my son at home when typing your name.
Anyways, let get back on the A-10.
Tell me what you know about fan system and provide data for other to learn about your works.
Since you like other fan sound better. Can you provide data of the system power and amps use ? How it perform in other model to get some comparison.
How many cell it can run on and what the weight will be end up?
All those information is very important to make EDF goes or not.

Tam,

Don't be offended that I don't like the sound. I already said your fan has good performance. Try to see the glass as half full! For some, the sound is meaningless. For others, it's not. I've had my name on the list for this plane for a while and for me (and obviously I'm not alone), a big scale jet's just no fun if it sounds silly. For plenty of modelers, that's a totally insignificant consideration. Like Ron always says, it's about options...

From what I hear, there are even more EDF options for modelers on the horizon very, very soon! This is a good thing, right?

Just to be clear, at what point on the video is the F-18 flying at "half throttle?"

Listen to it.....
Expert can tell when the model are on 1/2 throttle.
