I received my second Diablo from scratch and dent and flew it yesterday. Basically more of the same. This radio glitches as well, very disappointing. Very tail heavy. I tried the dual pod and it actually flew OK. It is quite heavy and does not have a noticable increase in performance. Not worth it. My wing came off twice in the air causing one very significant crash. Now my wings are glued on. Still experimenting with landing gear.

Correct me if I am wrong but a 4 cell lipo will give my upgraded diablo a little more punch than the stock 3 cell. Any good recomendations on battery and charger. Looks like the stock is only good for 3 cell. I have the recomended ammo setup, and I am hopping it will handle the extra current. Thanks

Erik St. -> RE: flyzone diablo (2/28/2008 11:59:37 PM)
I don't know much at all, but from looking at the Hyperflow website, you get a good bit more punch. Really rough numbers, but looks like %90 more power, %45 more thrust, and %25 greater efflux speed. I wonder if that means %25 faster? It does say that this is burst use only! I wonder why, if you have the 25 amp ESC and the 4s set up rates at 22.3A, what will fry if you use continuous power? >>>>>>>>>>edit, I looked it up, the motor is my guess, it's rated for 11.1V, 12 amp constant and 25A burst>>>>>>>>>>>>>>> I just ordered a $35 ESC and 4850KV inrunner BL for my Diablo and am really looking forward to seeing what that does with 3s lipo. I'll let you know.

northchim -> RE: flyzone diablo (2/29/2008 2:56:41 AM)
Erik St. Was that $35 for both motor and esc?

Erik St. -> RE: flyzone diablo (2/29/2008 2:49:45 PM)
Yes, $35 for both with shipping, very cheap, isn't it! Well, it's coming from China, on the slow boat. It will be weeks before I see it, but I just can't afford the $80 from LHS, if they even had the right stuff. Someone else said that when sending money to china, it's gone, and you just hope to get something. No returns or anything, just a gamble. So far it's worked a couple times for me, I hope this one is the same.

northchim -> RE: flyzone diablo (2/29/2008 3:07:55 PM)
Thanks. What have you heard about this motor? Someone recommended it on this forum. http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=3850 After thinking about the radio glitches, I wonder if anyone has tried moving the receiver to a different area of the plane? Maybe to an area that is more exposed perhaps. Maybe its just a reception issue. Can you put a receiver on the outside of a plane?

Erik St. -> RE: flyzone diablo (2/29/2008 4:00:05 PM)
I looked at that one too, but "out of stock". I can't take the unknown wait time! I've been waiting on a DX6I Spektrum too long, so what I did order was IN STOCK and it's still going to take a while. http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=4202 Maybe it won't fit, maybe it won't work, maybe these guys heat up too quickly. Time will tell, but I'm just happy to be out only $16.50. Going through life as a cheapskate like myself usually works, but you do have to accept the occasional failures of the cheapest thing on the market. Radio glitches: I've noticed that simply handling the ESC causes servo glitches! So I think sometimes it's actually on-plane issues rather than radio interference. SOmetimes it is external noise, but not always. I've got my RX wrapped in aluminum foil, the placebo effect works a little! I've just gotten used to the glitches, they seem very brief, and mine at least doesn't add goofy input, rather no input == glide.

northchim -> RE: flyzone diablo (2/29/2008 8:55:55 PM)
At 4850kv that's gonna be a screamer. What ESC are you going to use? Are you going to use the 3s LiPo that came with the Diablo or upgrade to a higher mAh 3s or 4s? If it works good I may install it in mine as well. I have been living with the glitches for now also. Maybe there's nothing that can really solve it. I am shopping around for a good quality radio I can grow with. Been looking at the Spektrum DX7 and the Futaba 7C. Do have any knowledge on these radios? I hear more good things about the Futaba.

Ok... First, Newjak this is Totalsnafu from Wattflyer. (Hi B!) The brushless has made improvement on the Diablo. Vast improvement. I did a little modding, at Newjaks suggestion, and made a "shield" for the pod. I used 2 plastic spoons (thanks Wendy's) and epoxy to make a sort of skid plate for the pod. [IMG]http://i122.photobucket.com/albums/o249/totalsnafu/100_0230.jpg[/IMG] [IMG]http://i122.photobucket.com/albums/o249/totalsnafu/100_0234.jpg[/IMG] [IMG]http://i122.photobucket.com/albums/o249/totalsnafu/100_0231.jpg[/IMG] The skid plate helps keep the pod intake off the ground. It works. On landing, I only had a little dirt kick up into the pod, compared to a whole bunch. One spoon was placed on the front of the pod facing toward the rear. The other spoon was cut in half and placed on top of and angling down toward the intake. I was generous with the epoxy (too generous in some spots and I need to sand it) so that it was secure and a bit harder. The spoon that's in front of the intake only slightly disrupts airflow, but takes the blunt of the landing. I'm going to experiment with mounting a spoon forward on the fuse to make a skid plate for the nose. When this thing lands, the pod digging in makes the nose impact from the sudden stop. My intentions are to make it slide along the spoon instead of having a blunt impact. I tried landing gear, and actually had rear and nose gear installed, but they add too much weight. The skid idea (thanks Newjak) keeps the belly off the ground and adds less weight. Might look a little funny, but if it flies, I don't care. Details of my brushless upgrade are here in this thread. Go back a few pages.

idealhobbies -> RE: flyzone diablo (3/1/2008 2:29:33 PM)
I also will be installing a DX6 receiver and the advanced wings in the next week. I do not trust the stock radio or receiver. I've invested too much time at this point to have to worry about glitches from a crappy receiver.

capepilot -> RE: flyzone diablo (3/2/2008 2:07:39 AM)
Relatively new to the game, but then again, it does not take long to realize this plane has issues. 4 launches on a fresh li-po battery and it could not get the strength to gain altitude. It miraculously survived a terrible first day. I have since purchased the dual-fan for supposedly more power but have come to realize that only one motor is working, the other is sporadic. Also, if it matters... it's not as good looking a plane as it appears. Once i get the power straightened out I'll paint it black to look better, then pray that I get it up and over the hill and I actually hope I never find it. Prediction...they won't be selling this product in 18 months.

northchim -> RE: flyzone diablo (3/2/2008 3:01:04 AM)
capepilot: forget about the dual motor pod, its too heavy for this plane. Just run the single motor with a brushless upgrade. Not the ammo though, get something with more punch. do you mean your diablo could not gain altitude with the stock set up? if so, somethings wrong with your motor, replace it right away. Mine has always been able to fly, my trouble has been radio glitches mostly. One thing I did was to "break in" the brushed motor with my charger. I heard it helps with power and I think it just might.

Erik St. -> RE: flyzone diablo (3/2/2008 3:48:35 AM)
oh ideal, you're my new hero, SPOONS!!?? awesome! we are all wasting our time on this plane, having lots of fun, and being ingenious. I have only used parts of kites, other planes, cardboard, and plastic packaging, but never a spoon! Good job. I can't wait to see how a BL 4850KV works, I will either tear the wings off or burn up something. Northchim, I have all 3s lipo, from 1500 stock to 2200. I ordered a "simple" 30A from hobbycity (china), but I think I may never see it. no answer phone, e-mail returned to sender "box full", money sent to china is a gamble. Lastly, capepilot, you bought an Edsil! relatively poor performance, but with some work it's lots of fun and a solid performer! Maybe it's because you overcame poor design, maybe because you are flying an OK model, but it teaches alot, and CAN work very well with technique and improvements. I still like mine (love-hate) after all our battles and I haven't even yet put in an upgraded moter!

northchim -> RE: flyzone diablo (3/2/2008 6:59:56 AM)
Erik St. How long are you going to wait if you don't get your parts?

idealhobbies -> RE: flyzone diablo (3/2/2008 12:56:01 PM)
What does it say under order status? Processing? They are slow when it comes to processing at the warehouse. HobbyCity is not fast by any sense of the word. Plan on 3 weeks to a month when ordering from them. You cannot be in a hurry! Another good place for motors is HeadsupRC on ebay. Jeff is reasonable with his prices and shipping is always $2. And best of all.... he's in the USA! Most of his motor/esc combos are $30. So, $32 shipped is actually better is some cases than Hobbycity, and you don't have to wait on the "slow boat" from China. As for the spoons, that was Newjaks idea. I just appied the idea to my specific case.

idealhobbies -> RE: flyzone diablo (3/2/2008 1:04:24 PM)
You guys need to take into account that this is a ducted fan aircraft. It takes longer for a ducted fan to get a plane up to flying speed. When you launch, you need to hold it as level as possible so that it can gain speed before pulling the nose up. When you do pull up the nose, especially for you stock runners, only pull up slightly and gain altitude slowly. Once she gets some speed under her wings, you can play a little more. Many ducted fan aircraft flyers use a catapult to launch their aircraft so that they gain more speed quickly. And I'm talking about planes that have way more power than our little birds. The plane is just too underpowered in it's stock form to throw and pull back on the stick. Even with a brushless, I need to let her go level to pick up speed, it just gets there much faster.

capepilot -> RE: flyzone diablo (3/2/2008 11:25:08 PM)
Northchim: The single motor that it came with is working fine, but as Idealhobbies has stated, perhaps it needs more speed before you pull back to get it upward. There's a wide open space from a hilltop that should give me some room to operate. Overall, it's a tricky plane that needed a 100 more hours on the design table. Having customers retrofitting tablespoons onto these planes really says it all. Other companies seem to have better products that really make it upward. Of course, trouble shooting and problem solving is part of the fun of the hobby.

Erik St. -> RE: flyzone diablo (3/3/2008 1:29:30 AM)
Idealhobbies said it well but I'll be like a parrot and say it again.... Capepilot, you bring up valid points, and maybe there is no such thing as a beginner jet? The Hyperflow design is optimizeed at 56mph, that's what it was designed for. And this plane doesn't usually do that except for a dive. Prop planes (generalizing here) are like tractors, they just pull and go. EDFs are like, ahhhh, uhh, jets! That's it, they're like jets. Diablo needs flat line speed for the EDF to work, sometimes I push "down" so it can build speed and then gain altitude and have fun "swooping". I go high off to one side, turn, drop altitude, gain speed, swoop by at great speed (for a beginner), and then climb to the other side and do it again. This is the Diablo. Lasty. I have moved the control thingies to the lower positions to get more throw on both ele and rudder. It's great! Loops and turns are sharper by a good bit. This did require drilling a larger hole, but I reccommend it once you are used to the palne. Idealhobbies, my beef with Hobbycity, or at least my concern is that I cannot get them on the phone, during china business hours, and not only do they not respond to e-mails, they don't GET emails; their box is full! And my account is not valid, my e-mail is not recognized by their system, despite the fact I received an e-mail from paypal, so I entered the correct e-mail. Can you check my order #200116254? I don't know how to check without account. And, although I ordered an ESC and motor, the paypal receipt only lists motor, yet the esc was in stock when I ordered. If you have the $$$, don't order from hobbycity, IMO.

northchim -> RE: flyzone diablo (3/3/2008 3:11:24 AM)
Guys, I believe a have a solution for the landing gear issue. Check this thread tomorrow night for a video from me.

northchim -> RE: flyzone diablo (3/4/2008 2:00:19 AM)
Forget about landing gear...try this instead: http://youtube.com/watch?v=PAjbqvjAu1E

idealhobbies -> RE: flyzone diablo (3/4/2008 2:21:37 AM)
Erik, I did a search for your order number and nothing came up. I cut and pasted their list into word and nothing was found. 102 pages, so I would assume that I had them all. I've never had issue contacting them. They have always responded to any questions that I had. Bizarre. Have you tried their forum? They do check that.

idealhobbies -> RE: flyzone diablo (3/4/2008 2:59:00 AM)
Northchim, OUTSTANDING! I was considering giving that very thing a try but had not decided. You just did it for me. One of the best mods I've seen yet for a sloppy bird. Thank you very much! Did you remove the thrust vector plate?

Erik St. -> RE: flyzone diablo (3/4/2008 3:44:04 AM)
I dislike that we are using two fourms, so I will try to start a trend and use this one; it has more posts. Northchim has had the most extreme mod yet, and I can't wait to see how it affects rudder and ele, esp up ele, right? I re-drilled my control horns to put the rods on the closest, most extreme, control authority position. It works well; I've heard the beginner usually 'over-controls' the plane. Well that has not been my problem on two planes, they don't do what I want. At last, with the rod attached to the hole closest to the control surface, the plane does do what I want, and quickly. I now have the ability to 'over-control' and stall the plane, requiring lots of 'up' to recover. Can someone who knows what they are talking about comment, is that what I'm experiencing? Anyway, still like the Diablo, and can't wait for the BL upgrade, should be sick.

northchim -> RE: flyzone diablo (3/4/2008 5:24:01 AM)
Yes, I removed the vector plate from the pod. I forgot to mention that in the video.

idealhobbies -> RE: flyzone diablo (3/4/2008 4:54:23 PM)
Just back from my "pod on top" maiden. Works great. The tail / rudder was not effected by the brushless. I actually think that the plane flew better with the pod on top. Nice job Northchim. Winds were at 12mph gusting to 20+, so the flight was a struggle because the training wings and wind do not mix. The plane bobs from any wind due to the wings design. She flew, and she flew well. Thanks. The spoons have been removed, and all epoxy cleaned off. My plane will stay this way. I've dubbed mine: Diablo Mk II. Again, nice job Northcrim. Next up, Spektrum receiver and advanced wings.
