I built the Fiber Frame tonight, added two Tower Pro 9g servos and added the titanium tail boom. The tail boom is secured by a single grub screw. I like that!

I'm impressed with the Fiber Frame. This frame looks good and is very rigid. I think I'll also buy the Fiber Frame for the HBK2, as well. Below is my anticipated setup.

Head/Main Shaft Components:

- Walkera #4 Main Gear w/Main Shaft
- HBFP Center Hub
- HBFP Swashplate
- HBFP Rotor Head
- HBFP Paddle Control Frame (Outer)
- HB CP2 Flybar
- HB CP2 Paddles
- 8 Degree Flat Bottom Wooden Blades

Tail Components:

- GWS CN12-RXC Tail Motor
- GWS ICS100E/J Brushed Speed Control 5A
- GWS Tail Rotor Housing & Vertical Fin
- GWS 4530 Tail Rotor Blade

Main Electronics:

- ARC-20-27-80 Brushless Motor w/9T Pinion
- Pentium 10A Brushless ESC
- Tower Pro 9g Servos x 2
- Spektrum AR6100E Receiver
- Telebee HH Gyro
- Commonsense RC 7.4V 800mAh 10C Lipo

I was going to purchase the Xtreme metal FP swashplate, rotor head and paddle control frame. However, I decided to begin with the standard HBFP head parts. It will still be a Super FP, IMO. I may add some bling later.

That looks like a good start to one kick ass FP. I could see wanting one of these. It's probably care free backyard fun. Even the king scares me in the confines of my backyard I'm not too worried about the heli, but when it starts to get close to me I don't like the thought of those blades hitting skin.

Looks really solid racin

I'm not sure how much more it will weigh compared to stock but you may want to consider an 11.1 volt batt instead of 7.4-- for a little extra -- UUUMMMPPPPHHH

racin, Do you find the DD GWS motor get's hot with a 4530 Blade ?? I have been using a 3x2 and never tried a 4530.

Nice Racin, very nice.

We need video proof around here.

The fiber frame with the titanium tail boom weighs 9 grams more than the stock frame and stock tail boom.

There are several guys who fly the ARC 80 in their modified FP helis over at rcgroups. The ARC 80 seems to be well suited for 2S. I guess I'll see one way or another. If you are interested, below are the specs on the Arc 80 (www.lightflightrc.com):

ARC-20-27-80
• ARC 80 watt inrunner brushless motor
• Kv: 4500, io: 0.57A (8V), Rm: 100 (mOhms)
• Weight: 29g
• 2mm Shaft
• Dimensions: 20mm x 27mm (w/o shaft)
• 4 Poles

Only 29 grams! It's a tiny little thing, but mean with power from what I hear.

My experience is that GWS tail motor gets very hot when it's mounted in the stock HBFP tail boom. This places the 4530 blade on the right side of the tail motor. However, when using the GWS Tail Motor Housing & Vertical Fin assembly to mount the tail motor, this places the 4530 blade on the left side of the tail motor. When mounted this way, the 4530 blade is blowing air across the tail motor, which helps quite a bit in keeping the tail motor cool.

I've also tried the 3x2 blade and the 4530 seem to give more snap to the rudder movements.

Great info racin

I see now that at 4500kv, a 7.4 bat will give some decent headspeed , 11.1 may be too much for the lil guy.

I'm looking forward to the added power. I've been flying a modified HBFP with the Slo-Max 300 brushed motor for several months. The Slo-Max is a high performance brushed motor; however, it's no match for the Arc 80. I think I will be pleased with the performance.

Based upon my calculations, running a 9T pinion on the Arc 80 at 7.4V will produce a headspeed of 1,927 rpm

. That sure isn't your typical FP heli headspeed

. I also have 10T and 11T pinions laying around that I may have to try. Those should yield 2,141 and 2,355 rpm respecively

. I don't know if the stock HBFP head parts can withstand those high headspeeds, but I'm willing to give it a try

. I may have to buy the Xtreme metal rotor head, swashplate and paddle control frame in order to work with the higher headspeeds. We'll see, but I know that I'm going to have some fun with this little guy.

I wouldnt use the stock flybar and paddles at that headspeed. It might just throw a paddle at you. Cant wait for the vid.

I thought I would give an update on my build. Everything went very well with the excepion of getting a proper CG, which was tail heavy. I ended up removing 1.9 inches from the titanium tail boom. So, the tail boom has been reduced from 12 in. to 10.1 in. Regarding the ESCs, the main ESC was a breeze to program using the programing card. The tail motor ESC is also working correcly, which only required a full left-stick input in order to arm properly. I've also spooled up the main motor on the bench and things look good including the tail motor operation and HH gyro.

One thing that did surprise me was the heavy cogging of the Arc 80 brushless motor. You have no way of "feeling" the motor pinion/main gear mesh. You'll have to rely on your eyes to ensure you are getting a proper mesh. The cogging is so pronounced that you are unable to spin the main blades by hand. Trying to do so would probably end of breaking some head parts. You can, however, grab and spin the main gear...but still you really get no feel for the proper mesh. Another thing that is highly recommended when using main motors with this heavy cogging is the use of an ESC with a "super soft start" feature. This will prevent stripping the man gear on spool up.

Anyway, it was a fun build and I learned that going the separates is really no big deal and very painless. I hope to maiden my Super FP sometime over the weekend. I'll keep you informed.

Looking forward to the Video -- should be a little monster

Hopefully there won't be any Whoop-se-daisy's

Well it's raining here in Indiana today; therefore, I don't believe I will get to maiden my Super FP outside. However, I did maiden the heli in my basement this morning. I was very surprised of the power of that ARC 80 motor.

I almost hit the ceiling punching out

. The heli is very stable in the hover and I can tell will be a fantastic flying heli. I can't wait to get this little machine outside! The heli also sounds great with that ARC motor turning those 8 degree flat bottom wood blades.

Anyway, below are some photos of my final build.
