RE: Ultra Rc Evolution
 

Hay Eric Sorry to hear about your plane. Hope it works out ok.

Could you tell me how much rise you need on a Muller header to fit the Evolution with the OS 160

Thanks Kirk

RE: Ultra Rc Evolution
 

Well,
I am waiting for the Ulra-rc corsair Giant to soon be released!!

I am sure most have seen the new model wit hQQ as built
My He looks as if he has aged a bit!!
QQ Looks happy though!
If I have ever seen a pattern/fun biplane worthy of my ZDZ 40f3a This is it....
Looks amazing

RE: Ultra Rc Evolution
 

That's not an Evolution..[sm=spinnyeyes.gif]

RE: Ultra Rc Evolution
 

But they charge 74.95 for shipping that only costed 25.00(Quoted by UPS Ground). 3-day is 58.00.

I am not usre what is the shipping charges prior to the sale, but now the only choice is 74.95 shipping.

RE: Ultra Rc Evolution
 

Brian......you are way off buddy. In case you are not aware, this ships as an Oversize 3 shipment with UPS. I questioned the shipping as well. I will take it one step further for ya.......

I used the same box they shipped the Evolution in to ship a plane to California......I took it to the local hub and the shipping cost was $128. They are not overcharging us, in fact, I am confident they are discounting the shipping.

Just my 2 cents.

RE: Ultra Rc Evolution
 

I somehow remember the shipping costing like 50 bucks when I bought it.

Anyhow, businesses do get a discount with ups. Maybe ups got tired of replacing the kits they damaged and upped the price. lol.

Either way, 50 or 75 dollars is still an ok amount for shipping. I pay 75-100 to ship planes of this size normally.

RE: Ultra Rc Evolution
 

I have been waching this thread now for a while and I noticed how nice this plane seemed to be in pictures so I decided to give one a try. I also saw how some were delivered damaged, I must say mine came today and they did a great job of shipping it to me. I guess I am faced with all of the other desitions to make like many of you guys have in reading this thread. I am very new in pattern flying and I may ask a question from time to time that may have already been asked so try and bear with me as I hope my plane turns out as nice as the reest of yours that I have seen on this thread. Thanks guys and good luck flying.

RE: Ultra Rc Evolution
 

Hey Chris, I bought an Evolution kit from a friend through Jarvis this weekend. I 've been following the build thread and talked to jay on the up grades to the wing. Looks like an easy repair to do, but changing the landing gear looks complicated. I've got a set of Bolly FAI gear that would fit but can't see how you fit a box in the fuse for them to mount? The pipe tunnel looks too tall to fit anything between the top of the tunnel and the bottom of the fuel tank floor? How did you change the gear? and what did you use? I saw post 303 and what you did. How tall is the rise on that header and the opening on the side of the fuse was already there?

RE: Ultra Rc Evolution
 

Chris J
If you decide to stay with the stock gear, I can tell you which rods I changed to and it's an easy change.
I read elsewhere about the tank floor( top gear plate) not having enough support in the forward direction and I agree totally. Adding some lite ply to extend that plate to F2 is simple.

The only other thing I think needs modifying is the length of the outer struts.I couldn't find any socket material that would fit SO I replaced the socket & the strut. I've had no problems with the mods.

I too purchased Bolly F3A gear as a possibility BUT decided adding a gear plate would be more work, add more weight and induce stresses on the airframe that I wasn't sure how to reinforce. So I stayed with the orginal concept.

Yes the mod to the wings is a piece of cake - just read Troy's suggestion carefully.

If I can help you any other way, let me know.

I am so happy with the plane I immediately purchased a 2nd one when they went on sale.:D
Eddie

RE: Ultra Rc Evolution
 

Hi Eddie, I have an idea on installing the gear plate, but was trying to figure out should the box walls be angled up or down? I checked out Chris's pictures and it looks as if the plate walls are going up and the gear fit down inside the box.

RE: Ultra Rc Evolution
 

I have an Evolution, I replaced the gear with Blloy F3A long . I removed the top plate made for the stock gear and put 1/4 inch lite ply plate to hold the bolly I attached it right on top of the pipe tunnell and braced it all the way around .Mine has near 100 flights on it with no problem. The retro fit to the Bolly is not hard and is by far better than the stock gear , I tried that with the mods and they broke on takeoff at about 20 flights. You can also use the stock wheel pants just use a Sullivan bracket to mount them and you wont have any problems with them .I fly off of grass all the time . Mine is set up with a Webra 145 two stroke and weighs 10 lbs 9 oz after the mods including the wing repair . Another thing you should look at is the shear webbs in the wings the first ones had the webs in horizontal and not vertical if you need to fix them Troy Newman has instructions on this in this thread ,not hard to do just takes a little time.

Now after all that the plane flies very very well with very little mixing it rolls so well you almost dont need the rudder , it will handle the wind well and is very easy and gentle to land, it is big and presents well in the air be carefull when you pick it up if you reach under the wing like you would to pick it up in the palm of your hand you will break the stringers but that is just a matter on learning to handle the plane, I reinforced mine around this area but no other problems . I have had no other problems It really flies well and is priced well also.

Good luck I would encourge you to look all through this thread it is packed with all you need to know ,several builds and many pictures

RE: Ultra Rc Evolution
 

Hey Chris.

How's it going man? Haven't seen ya for a while.
The gear plate is easy to do. Doesn't add much weight, and oh well if it does. The plane is pretty light. It can handle it easily.
I just removed the covering off of a extra fuse that I have so that I can explain this.
In pic one, the gear plate is installed in the third bay from the bottom of the fuse. I believe I used 1/4 ply for the plate in Vic's as he's a little rough on his landings. I can't count the number of contests I spent Friday and Saturday night rebuilding his gear on his Focus. LOL Good times though..
Back to post 303, look at pics 1-5. That's obviously Vics. If you look at pics 4 and 5 you can see where the gear block is glued. You just cut the covering and fold it back at the openings in the fuse, then slide the gear block in. Glue the areas where the block will sit before doing this when you install it for better bonding, as well as after its in.
Now for the tunnel side. cut away the covering where necessary. Cut your gear in half, and mount the t nuts as they are easier to get to now. Remove the gear after mounting. Next, I made light ply blocks for the front and back and insides of the gear block and fiberglassed it all to the fuse. Recovering this area with monokote royal blue. It matches perfectly. I probably have some if you need it. Also, after these pics were taken I added some light ply inside the fuse on both sides touching the top side of the gear to the bottom of the canopy frame. As wide as the whole opening from former to former. Vic has had some hard landings and he has sprung the gear obviously once as one of these has a small dent from the gear now. It's only for extra reinforcement. It must work. Vic's has held up fine.
I believe the rise was 2.25 but don't quote me on it. I will be attending the G'ville contest with him and maybe Hemet so I can measure it for you there.
Actually Chris, if you want me to install a block in the extra fuse I have and take pics, I will. It'll take me a few days, but I think I could do it within a week.

Let me know where I confused you here.

Also, what pipe are you running? I had to make the tunnel longer on Vic's also with a greve pipe. Easy to do also.
Just thought I would mention while you will be working on covering.
You can always call me, Jarvis has my home number.

Good luck,

Chris

RE: Ultra Rc Evolution
 

Oh, BTW
I have the covering off of a wing if you need pics of that also.
I am going to retro my wings on my Evo soon. I'll do a photo shoot while doing it. I don't think it will be tough.

RE: Ultra Rc Evolution
 

Hey Chris, can't make gardenerville but i'll be at Hemet and i'm going to Hollister. The wing looks pretty simple but the gear for glow looks as if the plate glues to the top of the pipe tunnel? I'm setting the plane up with an O.S. 140, hyde mount with nose ring, Mac's header and Haitore pipe. Do you see any problem with DS 8411 servo's in the stab, as far as weight? Anyway i"m going to start on it this week. Well i've seen one of those repair job's on Vic's Focus. And that was a job and a half. "The dedication to a job well done." LOL. Does that plane still exist?

RE: Ultra Rc Evolution
 

The plane exists, but somehow he ripped out the gear again and I haven't seen it to repair it yet. I had just rebuilt it and recovered the whole plane in my scheme for him when it happened. I told him to buy something else!!
He's looking into Bob Gillespies Gator Giles kit NIB. Guess who'll build it?? :D
I must like the abuse. LOL.

Anyway, the two that I have retro'd the block didn't glue up against the top of the tunnel as can be seen in post 303. The block is actually under the gear. Toward the bottom of the plane.
If you don't have it done by Hemet and I do end up going I could probably do it for you at the hotel in the evenings..

I don't know much about the jr stuff as I fly airtronics at this point. Vic's has some in though. I think they are 8411's. Not sure. Maybe someone who fly's 8411's could chime in. As for the weight. I'm sure they'll be fine. Vic's balanced easily with full size servo's in the tail.
I fly mini digital Airtronics 94761's all the way around in all my pattern ships, and they are much lighter in the tail.

I will say that you should look at post 304 and definitely add a piece to the back of the firewall. Mine still flexes, but not nearly as bad as it did.

Also Chris, check your stab incidence vs wings. I'm sure you read through alot of this. I just thought I'd throw it out there as alot of people have asked me what they should look at before they go fly. Not trying to bash the kit. Just a friendly reminder.. [sm=wink_smile.gif]


Chris

RE: Ultra Rc Evolution
 

Easy gear fix. No modification to the fuse. Works on grass with no problems after 80 flights. Shock absorbing!

RE: Ultra Rc Evolution
 

Chris J
I used JR 3421SA's in my stabs as I was going electric and concerned about the weight PLUS I got a good deal on a pair of them NIB. Had to make a mounting plate because the cutout is for full size servos.

I could've used 8411's easier as they'd drop right in and as patternflyer1(Chris) said the plane is lite enough it really doesn't matter but personally I think 8411's would be overkill( if there is such a thing):D

Eddie

RE: Ultra Rc Evolution
 

Hi Eddie, I've got 8411s just sitting around waiting for a plane to sit into. As far as the landing gear i've already made up my mind to change the gear out with Bolly's. I like the look of the plane with the bolly's instead of the stock gear. I'll try to post some pictures during the mods.

RE: Ultra Rc Evolution
 

Ok, researched your 8411's. I found out what they are.
When I first had mine together I had Aitronics 758 digitals in. They were a little heavier than the 8411's. I was overweight with them so I went to the smaller 761's. Of course, this was with the Axi and small packs (3700's)

I think the high torque factor will be fine. You may even like it. Besides, if you don't like the tailweight, you can always retro smaller servos in there later. But with the sliding cg, I don't think you will have a problem.
Are you running the os 140 like you were doing before??

Chris

RE: Ultra Rc Evolution
 

Chris J
I wasn't trying to talk you outta using the Bolly gear. As I said I too purchased a set as an optionbefore I made up my mind what to do.
I just wanted to share the info about the strut gear being viable with 2 small corrections to their design, in case you hadn't decided what you wanted to do. For me it was easier than installing a landing gear block, But then I thought the wing mod was a no brainer too :D

I even cut 2 inches off the length and still got ribbed for having landing gear designed for flying from a cow pasture. The really interesting part is I am at the exact same height as the Bolly F3A Electric gear but the struts with narrow fairings( I made these myself too) just make it appear tall.

You're right you'll probably like the look of the Bolly gear.
Yeah if I had a pair of 8411's laying around I stick in there without a thought. You can adjust the final location of the wing to allow for the extra weight if needed, but I think the design was allowing for full size servos, so the weight probably won't be an issue.
Eddie

RE: Ultra Rc Evolution
 

Eddie: no problem's mate, I like doing mods to planes just to see how far i can go with it. Any how off to work shop. Chris: Yes i'm a glutton for punishment. any way , hi ho, hi ho , i'm off to work i go.

RE: Ultra Rc Evolution
 

Hey Chris, I've been trying to call Ultra RC and leaving messages and e-mailing them with no answer. I talked to Jarvis today and he said to keep trying. I need the wing tube spar up grade from them. Do you have a number i can contact them at or different e-mail address? I wanted to finish this plane before the Arvin contest. PLease let me know as soon as possible. Thanks Chris J.

RE: Ultra Rc Evolution
 

Chris J
I have the wing tube mod from Ultra-RC and you're welcome to it. I decided to glue vertical grain spar webbing instead. It is really easy to do and definetly makes a strong wing. I wasn't convinced their mod reached far enough into the wing. If I try that method I will make a longer one. So either way I'm not gonna use theirs.
Give me your mailing address & I'll send them to you.

You're gonna love this plane.
Eddie

RE: Ultra Rc Evolution
 

If you go way back in the threads, you will see that (for the same reasons you are writing) Ultra rc and I don't see eye to eye. I had a very hard time getting ahold of them back then. So no secret number or email that I know of. I'll take a bashing if I say more..[sm=punching.gif]

Good luck!!!

RE: Ultra Rc Evolution
 

Ok Chris, i won't push the issue, are you coming to the Hemet contest? if so i'll see you then. Eddie: my e-mail address is "[email protected]" and thanks. i plan on doing both mods to the wing.
