Outrage 550 build pictures

Some pictures from the build over at Ade's on Saturday night ....

Thoughts on it so far...... all the CNC parts are very very nice and ultra lightweight. It's a scaled up G5 but with a lot more head tuning options. It has normal skids rather than the carbon angled forward skids on the G5, which tend to be a love/hate feature for some people.
Plastic parts are of a good standard, I've seen higher quality (Mikado as an extreme example) but these are plenty good enough to be problem free.

Reasonably easy build, a lot of screws/parts in the mainframes but otherwise starightforward.

It's a prototype so a lot could change between now and production which is touted at end of October.
The design is nice like the G5 in that where possible the weight is kept high for better axial cyclics.

www.blinktrading.co.uk are bringing in the kits and all Outrage stuff for that matter.

OK Ash, how big is it?
"550" may or may not mean a lot.
550 mm blades (.30 size)? or the same size as a trex500? (425mm blade) or slightly stretched "500" with unique sized blades?
your blog says no more either, and nothing at blinktrading, or helirect.

[Ashley Davis]

550 means 550 blades, so it's 30 sized. Testing in the USA has been with a Z30 Z-Power and 6S packs. In the UK I've lent Ade a Kontronic 45-10 and he will be using an Outrage 6S pack, not entirely sure what size, I think it's 5000mah.

Nice looking swashplate - I guess you can run 120 or 140 on that?

I look forward to seeing the rest of the build and some vids
Cheers,
Rob

[Ashley Davis]

yeah, swash is 120 or 140 depending on what holes you install the balls into. We had a couple of bits missing in the prototype kit (as expected, we were warned upfront), so it's going to be circa the weekend before it gets close to being flight ready while we wait for the missing bits to ship.

[moyesboy]

I've never seen a .30 size heli fly impressively. somehow the .30 nitros haven't got the power to weight ratio required.
Maybe with electric .30 might be the size that flies like a .50 nitro but isn't a battery killer. Though with electrics I reckon everyone just upgrades the motor until hey have eventually got a battery killer
If you guys like this heli you will be fitting 8 or 10 cells and flying for under 5 mins within 6 months.

[Ashley Davis]

we already have an 8S system specced for it but the flight time will be well over 5 minutes and the power will unreal (it's the same system Trev and I use in our 600E's). Apparently on 6S it's already ballistic, so we are holding back on going straight to 8S just to see if 6S is already enough.

Nice. The anodising looks like plastic on the photos though! How much of the heli is plastic?

[Ashley Davis]

very little, all the head and tail is CNC, the only plastic is the main gears and some of the frame components, like the radio tray, bottom tray and the boom clamp.

Why am I wrong to think that I prefer the radial servo arrngement of the G5 ?

[And why have they moved from that ? Something to do with the option of 140 as well as 120 ? Other trade-offs/architectural constraints ?]

[Smoothound]

The radial setup is a bit of a PITA to be fair. Although on a larger heli it maybe a bit easier to setup.

[trvo]

My guess is that the 'radial' setup stresses the output shafts in directions that they aren't designed to be stressed in (lateral rather than rotational). Moving the servos away means you can stick push pull bellcranks on there which mean you only have rotational forces on the servo output shaft rather than lateral movement, hopefully increasing servo life .

yeah it's a bit of a pain in the build but a god send in the setup. However, on a bigger heli is bloody hard to get all the servos round the mast nicely, plus with 140 and 120 options it would be pretty much impossible.

[moyesboy]

My guess is that the 'radial' setup stresses the output shafts in directions that they aren't designed to be stressed in (lateral rather than rotational). Moving the servos away means you can stick push pull bellcranks on there which mean you only have rotational forces on the servo output shaft rather than lateral movement, hopefully increasing servo life .

So this would be the best way then?
(actually, so complex i think differentness is its only advantage)


One day all servos will have a ball link on the servo horn screw and all the side load on the shaft will be taken on a reaction rod, or strap.

Servos are of course deigned to take the side load on the shaft (its almost always there on the fixed wing setups) that is why any decent servo has a ball bearing on the output. But we alwaya want to take out all the backlash and slop and we don't like the servo rocking - so we use closed loop which transefers the side load onto the T bellcrank, which has a ball bearing in the middle just like the servo output shaft...

The radial servo arrangement I have on my 450 (helidirect superframe) andf he biggest PITA with it is the servo output screws are not accessible without removing the servo.

[Ade_Law]

pushpull takes all the side loads off the servos output shaft bearing and mounting. the only load they see is a counter torque. this is much more accurate especially on larger models with higher loads.
