I've somehow found myself knee deep in the big Raptors and more and more I find I enjoy precision flying over 3D "tumbling" or "pop and lock" type flying. What 50 and 90 size airframes are considered good platforms for F3C style flying? Can I get there from here with Raptor 50's and 90's?

Simple answer, YES, you can use the raptor 90 effectively

Get a set of heavy paddles and a set of Radix FAI 710 or RotorTechs 700mm FAI (SG or unbranded yellow) and "go to town" practicing.

Come on up to our contest in Dayton and we'll give you a hand. Jumping in the water is the best way to learn how to swim. Once you flown the schedule and see other machines you will get an idea of what you'll want.

Older very competitive models include, Freyas, Vigors, Vibes, Caliber 90, and even the Align700 nitro,

New, if you are to commit suggest an electric setup: ENV, Vibe E12, Electric Freyas Opt, Trex 700f3c, and the more expensive Syphides E12, Eagles elec, and converted Calibers.

I do not know if TT makes anything newer dedicaded to f3c.

Well, Duh. I have two Freyas just sitting here. I have a set of Scott Gray 720's and the Rotortech heavy paddles w/weights. I guess I ought to get something together.

For the R90, remove the spindle pivot out of the rotor head. I did that with red dampers installed and it was quite interesting how the head performed. It flew significantly better.
I threw it around doing stick bang flying and couldn't get a boom strike either so F3C flying won't trouble it.

A few helis, this and that

Raptor 90 is a great platform for you to start in F3C,
Those heavy paddles ( 30-40 grams ) are just perfect !

Weight is around 5 kilos and with a good engine and good main blades (around 220 grams) it is a killer machine !

You will have a lot of fun.

I just started flying a Raptor90SE that I had sitting here forever and finally built. YS91ST w/ OS #8 plug. 12T pinion 93 tooth 7.92 gear ratio. Radix FAI blades, stock black paddles and the blue dampners with 2 shims on each side.

Hover RPM set to 1475 right now. Very smooth and stable. Running 1875 in FF and that seems pretty happy for now. Only 1.5 gallons through the motor and I am not pushing it. But it seems to have plenty of power and lots of smoke still. Running 30% CoolPower and using a Hatori SB-16FH pipe.

Futaba 14MZ with a R6008HS RX in High Speed mode. GV-1 governor and a GY-611 Gyro w/9256 servo. Radix 105 mm T/R blades. BLS 252 servos on cyclic, 9157 on collective (425 in-oz torque). 9252 throttle servo.

Fromeco 5,200 mAh Lithium-Ion pack with a Fromeco Arizona regulator. 5 volts to Gyro & T/R, 6 volts to the rest.

I am using a pull-pull on elevator and tail rotor servo mount with a CF rod, both from Quick UK.

Now I need to burn more fuel and continue to dial it in. It is very smooth and graceful in the air. All up weight with no fuel is 11.4 pounds (5.17 Kg) and it balances empty just a smidge nose down.

Sounds like a very nice setup. I'm setting up a Freya right now. I might pull back a Raptor and reconfigure for precision as well. What range of cyclic are you using?
