i've decided to jump for the raptor ship and go with the evo after i had a flight with an evo last week. soooooo much smoother than any rappy i have tried, including my own fully blinged one.

question i have is, what do i need to upgrade right away?

i intend to put on everything quick uk sell for the heli and either cx or infiaviation dampers, i don't know what ones to go for.

any mods or upgrades i should attend to during the build?

cheers

Metal radius block, delrin gears (upper, lower and tail pinion), good dampners, not much else. You don't need to bling this heli, it flies great more or less stock

You also might want to add the frame crossmembers above and below the fuel tank. Keeps the tank from being ejected in crazy high-G maneuvers.

now that i could see might be a problem.

what dampers are people using?

is there any reason why people have not put a knight gear system on this evo instead of paying £100 (uk price) for the hirobo upgrade?i would bet the gears are the same material.

also, does hirobo sell the metal auto hub seperate to the gears in the upgrade kit?

cheers

It doesn't really need the metal auto hub IMO.Some people think the alloy ones may even help auto unit bearings to fail a bit faster,at least on the 90 Freya where some had swapped back to plastic from alloy on the X-spec.

If Irvine /Ripmax won't do the DTDS delrin gears on their own at a sensible price,just try your hand at importing just the gears from Cyberheli or Ricks.

Now don't go confusing the guy! There IS NO machined autorotation hub for the Sceadu Evo. The machined hub in question is the hub for the lower gear when using the Delrin DTDS gear set. You still use the plastic autorotation hub that holds the oneway bearing.

If you want the lower delrin gear, the blue machined gear hub is required. I believe you can purchase this hub without the gears from RC Power Supply, but I don't have the part number. Undoubtedly Mr. Noodles will chime in with the right part number.

luckily i have a mate who has a knight 50 he doesn't use and i'm sure i can blag it from him to see what parts fit from the knight.

for anyone interested the knight and evo gears are the exact same spec wise, but i need to confrim if they will indeed fit.

the biggest difference i can see is the price, the main, second and tail gears in delrin for the knight is about 20 quid in the uk.

here is the evo parts beside the knight ones ( i can't find the lower gear on it's own but you get idea from pics)

I have to agree with Dr Lodge about how good the heli is stock.

Only other suggestion I'd make is to return your kit and get a HPM mechanical mix version... but thats obviously opinion, they both work great.

Yes there is, It is the same as the GPH's but with a sceadu sleeve.

Mine is an HPM also, I love the simplicity and "purity" of mCCPM.

if i wanted hpm i wouldn't have got rid of my rappy 50

btw, how can you get any simpler than eccpm? thats the whole reason for eccpm.

Raptorheli2, youre completely correct, how can one get any simpler than CCPM??

HPM is CCPM, so is SWM - don't confuse single servo non-CCPM, with mCCPM and eCCPM. CCPM just means the swash goes up and down to alter collective pitch. Raptors are CCPM too you know

The reason I refer to HPM as simple is that the electronics side of things is simple - no mixing and hence no interaction. eCCPM is mechanically simple but at the expensive of the electronic complexity required in the transmitter. You also have some mechnical interaction with eCCPM that you don't get with mCCPM.

if that is indeed the case (and i'm not going to argue) then why do ALL the top helis use eccpm?

i've had both and eccpm is far better imo.

ALL the top helis don't use eCCPM, take the Freya EVO as an example

I think the reason why eCCPM is so popular is that it provides faster collective speed and load sharing across the 3 swash servos. It is also more "direct" since there are normally fewer levers in the mechanism - its simpler and cleaner in that respect.

I tend to favour mCCPM with one good fast strong servo on collective, that's just my preference, but I have helis that are eCCPM and love them - Logo 10, Vigor CS, TSK Acrostar, and Sky Dragon (although its 2 servo CCPM)

eCCPM puts your servos at a significantly greater risk in the event of a crash. For relatively newbees like me this is important because I crash alot.

mCCPM give the servos a little cushion because the linkages can bend easier in a crash.

I already had one servo failure with my eCCPM Tiger50 after a crash.


Competition..... no expense is spared. eCCPM takes linkage slop to the bare minimum.

Following on from Dr.Lodge regarding the two Evo swash control
versions.Is it possible to get the std version as fast on the collective as the eCCPM one by just useing a very fast high torque servo on the collective.

I have the HPM version with a 9402 on the collective which is rated
quite fast and has good torque (best at 6V but i use 4.8)
but is not digital.The collective is still not what i'd call super quick even with the hole furthest out on the
collective push pull output arm to the collective cradle
arm and with Carbon X dampers.

It might be
"grass is greener on the other side" thinking on my part
but i'm wondering if maybe i should convert to swm instead and use 3 9252's.
Is SWM really that much faster?
Will the HPM match it with a certain collective servo?
Looking for a reply from anyone who fly's both Evo types
&has tried a few latest spec servo's on the HPM version.

Another down side to eCCPM is it tends to strip one of the
servo gears in a crash more readily when direct to the servo arm,than when the return shock
force from say a twisted blade grip goes from the swash via bellcranks to the servo.

Everything said is true. CCPM is quicker in collective but strips servos faster in a crash. I have owned probably four Sceadus HPM and I have just converted my latest one into SWM. It really depends on what you look for. But one thing that I can assure is that those mentioned 'interactions' and not that noticeable and very much depend on how you set it up.
I would not recomend SWM for a beginer. It is probably not worthy...

Now I do not own any non CCPM ship any more. Once you try it it is not way back.

PS. all my Freyas are CCPM.

I have both and tried 8311s 9252s, 8231s, and 8411s on both. The collective is definately faster on eCCPM. That being said I don't have enough receivers to fly both EVOs right now and I am flying the mCCPM. I got mad @ the eCCPM machine when I twisted my linkage up after a crash and it developed some interaction. MY mCCPM machine has no interaction while hovering (inverted vs normal) but it does have serios interaction on the far ranges of the pitch. At least with eCCPM I can work this out. I may go back to my eCCPM machine for a while.

Donkey you have the right to remain silent what you lack is the capability

WOW, look what I started with the whole CCPM / Mechanical mix issue.

If anyone out there wants to learn about the benefits and short comeings of CCPM than I would suggest going out and buying the Model Helicopter World issue in which James Wang compares a Conventional Mix EVO and a CCPM evo. I think its important to realize that either system is a series of compromises... you just need to decide which compromises suit your flying style and even your mindset.. because the differances in flight performance are so minute that if anyone of us had a double blind test with CCPM and mechanical mix EVO back to back I think almost noone could tell the differance in flight if both were set up well with fast high torque servos. The magic of the EVO's "feel" is in the rotor head. I love it.
