I actually think it flys just as well if not better too. I don't think the vector palste makes any difference either.

I am glad to hear that the extra thrust from a brushless motor doesn't affect the flight performance. That's great news. When I made that video there was sustained winds of 10-15 mph and the plane really struggled.

Let me know how your bird flys with the advanced wings. When do you expect you'll receive them? I am dreaming up another idea that has to do with the wings this time. I may purchase a set also to try out something crazy.

I should have them within the next couple of days. I ordered them last Friday. The plane really does struggle with the wind. The wings (trainer) are supposed to be for slow flight therefore do not work well in the wind. They flex a lot and the think that the wing tips actually cause a lot of the rocking that I get when it's windy. Any cross wind catches on them. If I can get this thing to fly good with the advanced wing, I may actually consider putting brushless in the duel pod. The pod would go on a serious diet first to try to lighten it up. It's just too heavy stock. We'll see. I have not made up my mind yet. I'm beginning to like to Diablo since I've gotten it to actually fly. Who knows, it may turn out to be quite a screamer with a little work. I'm also thinking about modding the canopy. It blocks the airflow with the pod on top. I may trim it down an create a slope downward toward the nose to make the air channel into the duct.

Northchim your very clever. you should replace the guy that created this plane originally. I want to address the wing tip issue, some people say they dont like the wingtips removed however I have mine cut off and prefer it. it seems more agile, albeit less stable. But if your flying it in the first place then its no big deal just move the stick where you want it and it will go there.

idealhobbies: I agree that the dual is way too heavy, however how are you gonna take off any significant amount of weight?

Canopy: Just a guess, but I don't think the canopy blocks the airflow much if any. The canopy top is rounded and to me it looks like the air would travel right over the top of the canopy and strait into the fan. I'm not an expert on aerodynamics though.

Maybe you can help me with my advanced wing idea. My idea is to mod the plane into a delta wing platform. Jets with deltas are very stable flyers and I think I can take some weight off at the same time. What do you think?

animal cracker: Hey, if you like how it flys stick with it.

Northchim: You and are on the same page. I was looking at the Salamander Jet that the Germans had in WW2 that had the engine on the top. Reason being it was going to fly from grass fields like we all do. So I thought I'd give it a try. It took all of 5 minutes to make the change. It actually flies a bit better, especially at launch since there's wind going over the tail surfaces right out of the gate unlike before where you had to build up speed. I do some slope soaring and might use this for that. Might even cut out the ailerons to make it a 4-channel with the big wing. I did try the duel pod and short wings and it flew like a brick. And to think, I was giving some of you guys a hard time for sticking with this. Silly me. I tried to upload a picture but it's been disabled.

Hey Paul, I have family in Pewaukee just off the lake do you know any Ackers? Anyway. Today I flew the advanced wing with the brushless. Its getting better but will never be a rocket. When you turn it still want to nose down a bit but not bad and when its time to land you had better be ready, not much of a glide path for this puppy. I also have no weight in the nose just the battery all the way forward. Lastly my engine is permanently glued to the bottom unfortunately or I would do the same as northchim.

No but I go down there and fly off the water during the summer with my PBY. I agree, no glide at all with the twin pod and short wing. Mine fell out of the sky when I turned downwind. Looked good crashing though. Glued it back together then sold the upgrades on Ebay. Don't like flying bricks.

North,

First, replacing the brushed with brushless motors will reduce some weight. I have not figured out the diet yet, I'd have to take a serious look at it. Delta wing would be cool. Try making one out of foam board. I was thinking around the same lines and was actually looking at taking 3/4 to 1 inch foam board and sanding and trimming it into a wing. I've seen several wing builds and was thinking about making a wing myself. www.spadtothebone.com is a nice place to learn about making custom aircraft.

Flew today with the wing tips off. It flew great. There staying off.
Bought a Spektrum DX7 today from ebay. As soon as it comes in, I'm chucking the Diablo receiver for a Spektrum. No more glitches.

animal acker: which BL/esc do you have?

idealhobbies: which BL/esc did you get? Where's a good place to get foam board?

Northchim I got the recommended ammo 20-40-3500 that is advertised along with the plane because I didnt know any better, but I read on the diablo junk forum that a james199 got something that goes 100 mph! I dont know that much about this brushless stuff and how to know what the kv means or mAh exactly its important that I learn it though. Also I got kicked out of the park by my house by the ranger, apparently there is a county ordinance against flying there. Is this Russia!

animal: I saw the post by james199 also. He's gonna have to make a video for me to believe his Diablo can fly that fast.

brushless motor breakdown: 20-40-3500

the 20 means diameter of the motor in milimeters
the 40 means length of the motor in milimeters
the 3500 means kilovolts or kv, or basically rpm

Hyperflow makes bigger motors that are optional in the Diablo. the biggest is an Ammo 24-45-3790 running a 4s LiPo it makes 48,000 rpm and efflux is 165mph. This motor sounds very like it would really rock.

If the kv or rpm is 3790 how can the rpm be around 48,000 thats a large difference also if you go to a 4 cell lipo dont you need a bec to install or is there a esc that has this included? I was told that if you go to a 4 cell that the esc would not be able to handle it and cut out.

Sorry I did not explain the kv very well. Using the 3790kv motor as an example: take 3790 and multiply by the number of volts in your battery pack 11.1v for a 3s Lipo, you get roughly the rpm.
3790 x 11.1 = 42,069 rpm

Your motor for example is a 3500kv. With a 3s LiPo = 3500 x 11.1 = 38,850 rpm

You have to have an ESC rated high enough for the amps the battery will put out. You could not run a 4s Lipo with the ESC you have probably. You would need to upgrade to a 35 amp ESC most likely.

Check out this hyperflow manual. Page 2 has all the optional motors recommended by hyperflow and the stats for them.

Hey guys Good to see some interesting mods have been done. Okay, so who's working on some light weight weaponry for her? I got my two, and was about to order 2 more when I seen $15 off $125! Two birds could have been shipped for $130! Not bad, BUT, they were out of the $68 ones. Mine has both tips busted, and some hard to fix damage to the tail. My brothers has only the wing tips damaged. His first plane! I hope to get out in the next couple weeks to fly. Busy here. I hope that perhaps hobbico reworks the diablo. It has great possiblilities. First, I think they should come with a brushless to start with.

All that said, if you guys could and/or would be willing, I would like to ask that if you are going to trash anything on you diablos, if you would consider selling them or sending them. I'm not really asking for handouts, so much as I am asking to help recycle. I'm not poor, but things are a bit hard where I'm at. If you decide to trash a radio/reciever, or motor/esc, please consider mailing them... not just to me, but maybe some other modelers who could use back ups or cheap crash solutions. Most of us are willing to
