I'm currently working on a conversion build.

Has anyone else done it ?
What were your results ? better or way better

Are you talking about putting a .50 conversion kit into a Hawk Pro or converting your Hawk to a Raven but leaving a .30-.40 size engine?

I'm betting he is asking about just converting the mCCPM of the Hawk Pro to the eCCPM of the Raven 30

I bet he's doing a Raven 30 head upgrade with a Hyper 50 and 550 blades with a 30 size tail.

I've read that this will make a WICKED 3D machine, just hope he uses a governor

The Hyper is designed to turn 600-620's geared around 9:1 (guessing at the ratio) and produce awesome results on a machine around 7-8.5lbs. To use it to turn 550's geared close to 10:1 (another guess at the ratio) is a waste of power/potential.

OS37 at 10.3oz vs Hyper 50 at 14.3oz is working backwards, your adding 4oz of weight in engine alone and gaining nothing in the rotor dept to help pull it around. That said the OS 37 and Toki 40 have power to spare when turning 550's so no real need to increase the power.

I'm guessing but I would think the Raven 50 and Hawk 30 are within 1-1.5lbs of each other.
So the real gain with running a Hyper 50 is in running the larger 600-620mm blades and gaining a lighter disk loading and increased stability.

Flown properly the Hawk left as a 30 in any configuration (e.g Raven30/Hawk30) has CRAZY power when setup and flown properly on a OS37 or Toki40.

Post the link I wanna read this and I may gain some insight on the logic used.

But also if you have not already then watch this video.
w.centuryhelimedia.com/videos/products/CN1000/HawkPro3D-AdamTurner.zip
It will show you what a 30 size machine can do in the right hands.

Please feel free to shoot down anything I have said, I'm using my own logic others may have better reasons for or against your question.

DOH!

You have to change the motor mount the pinion gear longer boom and drive shaft and 600 blades personally I would just buy the .50 and leave the 30 alone.

If you ever tried a aggressive pitch like +13-13 or 14+14- you would understand why it would be worth putting more power in the heli ........Should have no bog under extreme conditions! ...Just like E-Trex guys going from 6cell to 8 or 10 cell more power the better for 3D!

Well I stand corrected then, a Hawk with a 50 and +14/-14 would blow away a Raven with +10/-10 on the same engine.

Wonder why the 3D champs have not done this yet.

It's not possible to set up a Hawk to +/- 13 or 14 deg. collective pitch.
Mechanically the travel is limited to +/- 10 deg.

When installing an .50 engine, the way to go is to change the gear ratio, use 600mm blades and also install a longer tailboom!

+14/-14 just can't be done and is not needed.

I had mine set up with 14/14 pitch with a couple modifications.
but now with the Raven head I can get 14/14 without modifying.

I want to stay 30 size because it fits better in my car.

MY build has the following upgrades

Raven aluminum head with Blade grip thrust bearings, 6mm feathering shaft and 4mm flybar
Raven triple bearing Tail blade grips
(Forgot to mention the ccpm conversion kit)
Carbon tail support
Carbon rudder link rod
Carbon fins
Constant tail drive
Tail rotor driven with metal spur gears instead of nylon
Tail pitch slider
Large fuel tank 500ml
I want to use a 50 size engine with a governor to pull a 14/14 pitch.

The OS 37 can barely do it with throttle - aileron/ elevator mixes.

Electronic gear 700$
Engine and standard kit 350$
Upgrades plus 140$ slightly used

Now put this in a Masters hands a watch the feathers fly!

I beg to differ. My little Pro can go +14 /-14. I went ahead and decreased those numbers and even brought the ball links closer to the center of the servo.

Probaly because they are sponsored and fly stock to sell products
Maybe because they can afford the upscale heli's

HMMM... Super Hawk Pro

Myself I like to make hot rods
I would rather have a hopped up Camaro then a Porsche ( altough they can cost the same in the end ).

My Hawk pro has a -14+14 pitch but had to tune it down to -11+11
When my 37 finally dies maybe I'll get a 46ZXH or a Hyper 50
never thought to upgrade the head I like the mechanical set-up better
Let us know how it works out

Just change the ball length on your bell hiller arms, use a short and medium instead of a long and medium and you can easily get 14 to -14 or more degrees of pitch.

Hey Blade_Master1, I have also installed a metal head, 6mm feathering spindle, red dampers, triple bearing with thrust bearings in both main and tail rotor in one of my Hawk Pros. I also have most of the parts to install the 4mm flybar but have not done so yet, but I only have an os .32

First Maiden flight on project Super Hawk

Finally got it built,after a little bit of trimming I did a couple of circuits.

WOW! What a Change! I thought it would be way too nimble for me to handle but it flew better than I could've ever imagined, it was very stable it turned on a dime with way more precision and a feeling of control.
The head upgrade was more then worth the money,
Even with the OS37 it had a very good climb rate.
With the 500ml tank I was getting fantastic flight times of 25 minutes.
I use to get 3 tanks per battery charge but now it's barely 2 and I was in the red when I landed after the second tank, Talk about a close call, If I had been doing more agressive flying I would surely have crashed due to lack of BAT power.
I'm not sure if I'll add a second 4 cell pack to increase Mah's or maybe I'll just do fast charge after each flight.

The next phase of the Super Hawk project will involve the use of a Hyper50
and a GV-1 as soon as funds become available

Electronic gear 700$
OS37 Engine and standard kit 350$
Upgrades 140$ plus slightly used

will you run 550's with the hyper or use the extra power to spin 600-610's and really bring it to life......trust me it will still fit in your car

Stretch it !!
