mv71,

Excellent, I'll have a look at that, and yes I would like a copy of the PDF;)

Glad somebody likes asymetric schemes, as that's where we're going with the new stuff.

Wils is keen to get into the leccy market, and hopefully the mini adrenaline will become a production ARTF soon. I think I might make a Depron version in the meantime, if it's successful I'll send on the plans.
I'm a bit green when it comes to LiPo packs, what size are you using?

Sym..
Just a quickie..have you, or are you about to use, or even is it recomendable to use,...:)this bracing that Wilson was on about, on the...the... Eppenage.!..yes thats the word..:).he sid all the bracing support is already there...last time i saw him a was on about carbon rods under the horz stab.. what do you think...;)

RE: Freestyle Rush
 

Empennage? That's the turtledeck. Do you mean the bracing for fin/stab/fuz? If that's the one then if Wilsons recommended it I won't disagree.

I haven't bothered on mine, as the tailplane is very strong on the Cyclone. On one of the first flights I had high speed flutter due to sloppy links. The tailplane was a blur, and it actually compressed the fuse sides by a couple of mill, but the stab was fine. The kit has some hard spars across the stab centre 'cause Wils is paranoid about tailplane failure. Probably why he's recommended it.

At the end of the day, it gets dark and we go home (sorry). At the end of the day it ain't adding any weight, there's hard points in the surfaces to take it, and I suppose it's better to be safe than sorry...

Anyway, it makes a soothing whistleing noise at speed...

Is there any way to set this thing up so it lets you know when someones replied?

yes..." forums " then " forum settings " click the circle just above the "upload my custom avtar" bit....i just get a cold shiver....:)

RE: Freestyle Rush
 

Aha, that's clever, well done that man...

Spacey,
Still haven't been able to confirm Rush C.G. Will post when I find out.

Sym.

RE: Freestyle Rush
 

Hi Spacey

CG for the Rush is suppose to be at 100-110mm. My mates Rush that I flew on the weekend is at 78mm. The plane had 2 servos in the tail but he didn't like the way it flew. At 78mm it is great for pattern and pretty good for Hovering.

As for the Rush snapping out. Evertime I pulled up for a hover, it would roll out. Always to the right and only when the plane was heading up. Was it me putting in right rudder while pulling elevator? I don't know. (I don't think so) I didn't think it was a problem, I would just catch it and start to hover.

Danno if this helps any.

P.S. I have photos of the Rush with the OS 91FS in it, but haven't got a clue on how to post them

RE: Freestyle Rush
 

Buzz Good mornin to ya..!

Have i read that right ...thats an inch further forward than the recomended C of G......SYMMMM...?:) ....Buzz, whats ya weathe like.?:)

RE: Freestyle Rush
 

Hey guys! Lucan yes the pull setup I got on the bird is setup like you guys described it. Clevis on hinge line and distances the same thing. :D

I didn't get a chance really to fly the plane yesterday. The exhaust bolt broke on the first flight. [:@] .... My bad!
I over tightened the thing. O well only 50 bucks and i'm going again. Nothing too serious, though I do think OS spares are way over priced here.

Buzz mine also always rolled out to the right. I wonder if it could not maybe be the CG that is too forward? I have to move it back and give it a go. I mean I can't lose much. Maybe going to need a drink afterwards but hey! I am not scared! :D I just wish I had a better engine for it. The 46 will never do the trick. But I guess it might be able to harrier with that engine. So there is still a little hope for some 3D action.

RE: Freestyle Rush
 

Spacey...GOOD..:)....hardly slept a wink all w/end thinking about this ;) catch ya later got to take the kids to school..!

RE: Freestyle Rush
 

Mmmm, problems, problems. I just don't know what to say for the best...
Wils is back in the country, let me see if I can get hold of him and confirm comments from others. I'm sure we was recommending 4"
78mm, that is far forward. But hey, if it works who am I to say.
As for pulling to the right, you would expect if anything it to pull to the left with either torque or gyroscopic precession!
Let me do some homework on this one.

Sym.

RE: Freestyle Rush
 

Yes well, interesting that the Funtana S40 has the exact same problem. I'm still very sure that we are missing something very small on both these planes. My Funtana is nearly finished. Just have to glue the canopy and do some small things. Should be able to maiden it on friday. I wish Ali would jump in here again. I am starting to doubt the wingloading thing a little bit. I was wondering if any of the guys using the bigger engines are within the recommended range on the box?

RE: Freestyle Rush
 

Hey ...:).....Idea...[sm=idea.gif] its not because your in the southern hemisphere is it....y'know water goes down the plug hole the wrong way and all that... ..sorry....:) i'll shut up.!!...:)

RE: Freestyle Rush
 

Lol....I wish that was the case. Imagine hovering with the spinner pointing at the ground. :D

RE: Freestyle Rush
 

Okay, we definately tell our customers to set the C.G. to 100mm (4"). If it's stall manouvres your trying to do, like harriers, then you need heaps of movement to attain a state of dethermalisation, this applies to any model. Also if applying large amounts of elevator it could deform the elevator joiner to give a momentary throw imbalance on both surfaces.

Sym...[:-]

Indubitably...!

RE: Freestyle Rush
 

Guys
I am off line for a couple of hours and Bang!! 10 more posts. How am I suppose to keep up??

Spacey, years ago I tried to hover a plane with the nose pointing to the ground.......ended in tears! hhehehee

I was supprised to see the CG at 78mm myself. If it were my plane, I would move it back. But, it is his second plane and he likes it the way it is.

Cheers

Buzz

RE: Freestyle Rush
 

That is alot forward. I am going to try it more back. I also wonder if the plane would not do a little better with a 12.25X3.75 APC. I asked the LHS to get their butts in gear and get a hold of the stuff. It's rediculous that we can't get hold of the stuff that works. South Africa really sucks in that respect. The whole only import what has been proven to work thing annoys me! [:'(]
I will take the Rush out this weekend. I hate this beating around the bush thing but work doesn't allow me to take any time during the week to fly. The Funtana is nearly finished. Then I have to quickly finish my dorked Profile Gee Bee and then the Rush will resume the main spot on the building board so I can sort it out. So hopefully by friday night it will get some attention.

Sad thing is it still growls at me every time I look at it. :D I do not consider myself to be an expert pilot and this thing scares the hell out of me. Some people say my GP Super Decathlon is a dawg but heck no the Rush takes the cake! :D :D

RE: Freestyle Rush
 

God... did I swallow a dictionary yesterday or what... Lack of sleep I think!

Spacey,
I hope you get your head around the Rush, it really does fly nice. Problem is if a model scares you even before you fly it, then you can't really settle down with it. Ali had the prototype Rush with an Irvine .53 and a 12.25 x 3.75 APC prop. I had a go with this when Wils had it back for evaluation, and although it had heaps of punch it did struggle on bigger manouvers. Perhaps Ali could jump in here and give his opinion?

Sym.

RE: Freestyle Rush
 

Spacey

IMO, I wouldn't go with the 12.25x3.75. If the Rush had a constant cord wing and liked to fly around at a crawl, then maybe. The Rush needs 6" of pitch. Don't get me wrong, I am sure the 12.25x3.75 will fly the rush around and it would be good for hovering, but you will need to land and change props if you wanted to fly pattern or do knife edge, large loops etc.
Do not be affraid of the Rush. If you can fly a Super Decath, the Rush will not be a problem.

Cheers

Buzz

RE: Freestyle Rush
 

Good point Buzz.
Maybe I should just put it aside till I can afford a bigger engine for it again. Maybe a Saito will do the trick cause their very light but oh so expensive. :) The only problem I have is that not even the 46 will provide any fun flying pattern really. The plane is just too heavy. My 61 had trouble hovering the bird. Maybe a nice saito 91 or something is needed.

Time for another theory. What if the flaperons actually was pushing the wing over stall quicker? Like the whole more elevator throw thing. I've tried the stall strips on the inside of the wing but that did not have much effect. Do you guys also have a bad wingrock in a harrier? Am I maybe just not getting the nose up high enough? Moving the CG back must surely help with this? But yes it could of course provide quite a bit of disaster as well. :eek:

RE: Freestyle Rush
 

For sure the 12.25x3.75 was not the best prop for all round flying. I had it on the first rush to try and unload the engine and keep speed more constant.
I am now pretty sure that the rush is more suited to freestyle aeros than out and out 3d, Having flown one recently with a os 70 Ultimate and set up soft for freestyle/pattern flight I felt much more at ease and the plane responded a lot better. It is my opinion that the smaller models are harder to 3d than the larger models. Dont get me wrong, I can prop hang and torque roll my rush all day, and when it is in that sweet spot its great. The problem comes at the point where the wing is just starting to become useless. I think Slym used a better description of this than I can. The smaller models with the higher loadings can be areal handful until the wing is fully stalled.
I am sure that the thin air in South Africa is also making this problem a lot worse. I was there last year and somebody let me have a go of a 3rd scale aeroworks edge. Now this is a plane I know 3d'd but at 3000 feet I found it impossible to do anything nicely. As soon as you fell out of any stalled maneuverer it was a nightmare trying to catch the dropping wing. Also this will affect power. A model that 3d's in the Uk with a 46 will struggle with the same engine over there. I have been through all the possibles with Stacey via email and my only possible fix is to emigrate.

RE: Freestyle Rush
 

Lol....Yea Ali I think you might have a good point there! Were you flying at the Jet Masters here last year?
