Each week, you can add a drop oil in the red places, switch you helicopter on, and do not forget to move corresponding servo while adding oil.  I'm using stich machine white Vaseline.

90 deg. CCPM by CK_

When in MMS mode, move the link from the blue ball to the red ball. Do this on both side of the swashplate.

All credit to CK_ "As for the 90 deg. CCPM, here's why I did it. I started with the stock 120 deg. CCPM with 3 9202s. If I banged the cyclic around quickly there was a lot of collective interaction. Try it for yourself. Wiggle the cyclic and watch the antirotation pin and jump up and down 1/8". The interaction happens because the servos are slow and the front swash input has to move twice as fast as the two in the rear for a fore/aft cyclic movement because the front ball is twice the distance from the center as the rear balls. If you move the cyclic faster than the servos can move then all three servos will move the same speed (the max speed of the servo) and collective interaction will happen because the front swash input is not moving at twice the speed of the other two. Curtis' 140 deg. or whatever it is on the Vigor CS puts the front ball exactly the same fore/aft distance from the center as the two rear balls. This means that all three servos move the same speed for a fore/aft cyclic input. No interaction. If you use 90 deg. then fore/aft cyclic only moves one servo. There can never be interaction if only one servo is moving. Lateral cyclic will move two servos at equal and opposite speeds. No chance for servos to "run out of speed" like with 120 deg. I still get a little bit of interaction but it's nothing like I had with the stock setup. Like I said before, I still don't know why 120 deg. is pretty much the standard and 90 deg. is rarely used when 120 deg. has much more collective interaction. Anyone got any ideas?"

Great response by Dr.Ben "Your info about the 140 degree CCPM is entirely valid. One drawback of having the single ele input up from is that the swash is less stable. 120/140 d. CCPM surrounds the entire swash with support. There is also a control power component here. One reason the big gun CCPM models such as the Fury and Vigor CS can pull such abrupt maneuvers is the combined input of the servos - two for any roll command, THREE for pitch command, and three for a collective command. 90 degree CCPM takes two servos out of the power equation on the pitch axis. I realize the control power issue is of less consequence in a 30 sized bird, but you asked why manufacturers don't employ 90 CCPM more commonly. Much of the interaction you saw is a direct result of the somewhat slow analog 9202's (still a hell of a good servo) and not the 120 d. CCPM per se. If you go to a upper or lower collective command and input a hard over roll input, you will note a pretty good collective interaction because the servo arm on one of the two roll servos is approaching centerline and thus moving its pushrod further, while the other servo arm is retreating from centerline and moving the pushrod less. This differential phenomena is present in all CCPM models with rotary servos and is somewhat minimized by using servo wheels large enough to avoid movement a large number of degrees off centerline. A linear output servo is the only way to avoid the problem completely; we ain't there, yet <g>. The Caliber 30 system might work a bit better better if the bellcranks were designed to create less swash travel per unit of servo movement (meaning equal ball input points on both arms of the bellcrank), and then larger servo wheels were used to get the collective/cyclic range needed (less differential effect).

	Kyosho part CA3035 Some parts right out the bag are prone to break. Verify yours and replace them wth a raptor 30 if needed! "Almost directly accross from where the set screw is installed was an imperfection in the aluminum. I pulled on the part with my hands and could spread the piece and it proceeded to break in two. I also tried the same thing on the part with no visible problems and it would not budge." by choppengruven Discover by in France by Claude and Laurent Lombard
	QuickUk sell this one.

Symptoms: Engine overheating Loss of power even if the motor smoke a lot Why? it really depends... Where You are living....in the desert? do not forget that some gyro may have trouble too and may drift a lot if the day is too warm (more than 35°C). In altitude, less oxygen -> more nitro The percentage of nitro/oil the more oil/nitro the cooler the engine will run -> Attention here in europe, nitromethan can cost an arm and and leg -> 30euro/liter !!! at 15%nitro. I personaly usually fly with 1% nitro! enough for learning. You engine is not correctly tuned, ask a better pilot to help You set the engine. Your engine MUST smoke If nothing of the above aply, You may want to try the mods below

Cures (expensives) Change the cooling FAN for a QuickUk Change the cooling FAN for a Correct upgrade. Look below for others...

Build a plate with aluminium or plastic you can bend with heat. You must create a U shape and use the screws (red point on schema) to fix it on the frame

+ Less ugly, moreover the R30 V2 is really nice (ok, it's not a princess but this is a personal point of view)
+ Real windows for watching the battery monitor,
+ Access to the needle, can be finally adjust realtime,
+ Lot lighter ( vs 237 grammes for the original canopy),
+ The exhaust can not melt the canopy ;-)
+ Better cooling,
+ Cheaper 30 size canopy of the market ($19).
+ Body retaining is easier, faster : 2 grommets instead of 4 "easy to loose" screws
+ Survive to many crash.

Take a look at the caliber 30 manual, page 17, remove the 2 screw number 948 and replace them with philips screw or similar. We need to remove them because the are not suited for the raptor 30 canopy.	You shall move the "hook" to the nearest position you can (to the edge of the canopy)
You can cut the edgebut it is nott needed (not done on picture)	Cut here in order to let the swashplatte moving freely. Cut the canopy to let some space between the muffler and the body if required.
- The 2 fixing canopy screws (page 17, part 949) are iritating and if you don't forget to overtighten them, then you can loose one in flight. The best solutions is definitively to use the thunder tiger system part: PV0061	Caution : I tried Fabian Wiedemann fiber canopy (well known brand in Europe that fit well on most 30 size). They can not be mount on the caliber, the radio tray is hitting the inside windows of canopy.... You've done it! Result is below : 15.11.2002 Kyosho now sell a fiber canopy:
