Hawk Pro - Flybarless and eCCPM
After upgrading my Hawk to FBL, I experienced some flutter. It appeared that it may have been caused by the play in the collective assembly. I am happy to report that after upgrading to eCCPM the flutter is gone. The video is a bit rough, but it shows that all seems to be working nicely.

Yeah OS 37 running 30% and the gov set to 18450rpm / 1890 headspeed. I'm starting to feel the need for more power.

Glad to see that you got it all together with the upgrades and it is working good for you.

What muffler do you have there? If it's not hitory then to get something close to give you more power would be upgrading to Hitory or Toki 40 muffler. I had that muffler on os 32 gave me great performance. It's high quality muffler that not much know about. People at my club went for Toki 40 muffler because they produce great power like Hitory for fraction of the price. I think it's around 40 bucks for the muffler at Mecoa.

I've been debating going fbl on my hawk using an rjx head. I'm surprised that the ccpm conversion made that big a difference. I wasn't going to go that far with it. Might have to now.

The old Falcon SE was the mechanical CCPM version of the Raven. The Falcon used the same mechanical Collective Cyclic Pitch Mixing system as the Hawk.
Over the years, I logged many hours on both helis and found a big difference in the two when set-up for for high rotor speeds used for 3D. Consequently the Falcon was fit into a scale body. One thing of note, was the direct to swash eCCPM system in the Raven, required more powerful and expensive servos, and the gears in the servos did not survive crashes very well compared to those in the Falcon. (That is one of the main reasons that I really like the current push/pull bellcranks systems used in their latest Swift and Radikal designs). Unfortunately, Century has had the CCPM conversions on B/O to me for quite awhile now.

What Hawk do you have? If it is the Pro then it will have these feathering spindle spacers in the rotor head. They make a huge difference in how the Hawk response to 3D flight.
http://www.centuryheli.com/mm5/merch...Category_Code= Also going from analogue to digital servos will help a lot - even a basic digital servo like the Futaba S3151's.

If you do not have a governor, then setting up high value elevator to throttle and aileron to throttle and right rudder to throttle mixes (80% to 100%) as described in steps #4, #5 & #6 of this article will also step it up a notch (I would recommend this even with the eCCPM conversion.) http://www.leisuretech.ca/index.php/...faster_cyclic/ As for FBL, installing an FBL head like the CN2517A will also help, specially if you have a powerfull engine like the OS37 or Toki 40, as it will allow youto set up a greater collective and a greater cyclic pitch range then any Flybar head will. Here is an example:

The servos are the standard inexpensive S3151 Futaba servos on elevator and aileron, with a higher torque Futaba S-9251 on Collective. For throttle, it has an S-148 is plugged into the inexpensive Model Avionic TJ Rev Max governor. For the tail rotor, it uses an old Futaba GY-401 gyro with the designate S9254 tail rotor servo. Of course the great Rotor Tech blades help a lot in the performance. I have also flown it a lot with the gray FunKey CNF6026 blades and it still performed very well. All of this makes for a relative inexpensive package that performs very well. This little heli now has well over 600 flights on it.

Hi nice flying machine! That Toki 40 was a great engine until we started tuning it. Once we touch that needle it was a disaster. With experience heli flyer we could not get my Toki 40 to tune and was a lot of issue afterwards until I replce it with a os 32 that was frozen. I soaked it into fuel and then lub it then cleaned the carb and installed it on my heli with the Toki 40 dedicated muffler and it just never lost a beat. Question did you ever touch the needle? What fuel are you using? And yes that engine had plenty power like my old Trex 50 with OS 50 Hyper with align muffler. And where did you bought you're engine? Mecoa?? Grey engine or silver?? TY

Fortunately, when I read the instructions (I noted they were the second version of instructions) before I first started it, and noted that it asked for a 3 1/2 opening of the main needle rather then the 1 1/2 that was common with the OS's. I also noted that they had a much finer thread then the OS's, much like that on some racing 40's from Europe that I ran in the early 80's. So I would start at 4 turns open to insure an adequately rich mixture and tune it from there. I bought my two engines from Century/Heli-World when they used to sell them. I even bought some extra bearings at the time as they were less then those for any other 30 sized engines I had ever ran before (OS, Enya, Webra, Irvine).

I have always ran Cool Power 30%.
Sorry I cannot take pictures of the Toki at the moment because it has the OS37 installed currently. I found the Toki bearing fits the OS-37, so I installed one into it and am now using it in the heli to see how long it will last in the OS compared to the more expensive OS bearing.

Oh IC I heard the grey one is a clone of the silver one. I heard Century or Heli world made the grey
one but silver made by Toki. Heli World or Century copied Toki engine. Mecoa even agreed that CEntury grey version is copied now Mecoa bought the mechines by Toki since Toki went out of business. Mecoa now stock Toki been a long time this happen. Anyway's I heard grey one has more problem then Silver one. Which one do you like? Which one produce power? And does both has same Toki muffer? Even though both engine always had issue at my club.

As I already knew of how well Toki was respected in Japan for their small ducted fan, I purchased one of the initial grey ones as soon as they came out. It proved to be as great an engine as their ducted fan engines. Unfortunately, at that time, the economy in Japan was taking a nose dive and Toki, along with many other smaller Japanese manufacturers had to close shop. That is when Macao bought their remaining stock. To this day, I do not think Macao manufacture anything, they seem to be more of a liquidator. Another example of their liquidating, was with the famous HB and HP lines out of Bavaria and Austria and the Rossie line out of Italy. I do not think they ever subsequently manufactured any of these. I believe they only have assembled some more engines from the remaining parts inventories they had bought from the bankruptcy sales of these companies.
