I am trying to plan what I am getting with my raven .50 I am soon to order and have some questions about some of the things I am going to order. I am going to get the raven .50 combo from tower hobbies. it shows a white canopy and all of the other sites I have looked at shows a yellow canopy. does anyone no what color the tower hobbies model actualy is. also the engine is a O.S hyper .50 ringed which glow plugs should I get? I was looking at #8 long and medium. Should I get a exaust deflector? The starter that comes with the field box combo I was looking at has something on the front that is large and round like plastic wheel. Does the starter hex wand fit inside of that? ( sorry to sound stupid but I am when it comes to this nitro stuff} planning on getting the 4.8v 2000ma receiver battery don't want to large incase it will not fit. is it better to get glo starter or is there one that can be installed like I have seen on the TREX 600 called a 2-n-1 except I will not need the voltage regulator. Is it ok to fly without a govenor using my DX6I and a ar6200 receiver and than switch to 7 channel TX and RX later. IN a RC heli test of the raven they used Hitec HS-6965 servos on the swash and Hs7966HB on the throttle. they didnt say what was on the tail but I was going to get the GY401 with the S9254 tail servo. What type of fuel filter the one i am looking at is in line between tank and engine. In RC Heli they have it there but there is an extra nipple on filter with a plugged fuel line ( I don't know what this is for. Any info will be helpfull

1 - Get the OS#8 or the Enya #3
2 - canopy color? Best to ask Tower. I understand their last production runs were all using the yellow canopies. Maybe the ones from Tower are also with yellow canopies but they have not changed the picture on their site.
3 - Start wand, without a link to a picture, it is hard to say for sure, but that is usually what it is. The one from Century that I have will do both - it will slip into a start cone or it will attach directly to the starter shaft if you remove the cone. As I hardly fly my airlanes anymore, I like to attach it directly to the starter shaft...it makes for a much neater and more positive attachment.
4 - As the Raven has a tendency to be a bit tail heavy, using a bigger RX battery up front ofr more flight time is a plus. I use the big 2400 C sized NiCd's in mine. With all digital servos you will probably be safe with the 2000mah pack for 3 flights.
5 - I prefer the seperate glow starter (get one with a meter so you will know if you have good contact) and a remote clow attachment.
6 - Yes, you can fly without a gov, it just takes awhile to learn how to set up a proper throttle curve in your TX to match your collective pitch curve properly..I would bet the vast majority of us learned to fly without using a governor.
7 - Gyro/servo, the 401/9254 will work very well.
8 - The inline filter will work well, when you refuel be sure to do so from the line between the filter and the tank. The T-filter uses the third inlet as the line to refule from. But you must be sure you pinch off the line between the filter and the carb when you do so.

thanks Rav50 on the glow plugs #8 im medium or long? in answer number 5 what attachment are you refering to? If the fuel filter doesn't have the third port where do you refuel? what about the swash and throttle servos I mentioned? Thank you

I just pull the line off the carb and fuel there.
If you want $100 servos for $40 look at the hyperion DS20 line. I have them and they are tough.

Is the DS20-HMD one that can be used on cyclic and throttle

The OS #8 plugs only come in one length....long.

Yes .15 deg/sec /// 99.9 oz./inch @ 4.8volts
If you want a little more the ds20xsmd coreless for $48 is even better, 0.13 sec and 194 oz/in.

and that can be used on throttle as well. and is rebuild kits available and I guess they are digital

On throttle you will be fine with a lower torque and slower servo then on cyclic - even a low cost analogue like the S-3001 Futaba servo will do fine.
Hey guy, hope you can help me on this quagmire. I have been flying electric for a long time and have just received a few Nitro Heli's from the 40 engine size to 95cc engine size on a swap deal. I use a DX6i on all my Helicopters and set the programming up as I would with an electric however I have a throttle and a pitch servo that I can not get to work together. I can get the throttle to work for the carburetor but the pitch is not moving the swash plate up evenly but the aileron want to move it up only in one direction for what ever reason. If I take the pitch away from the receiver and connect it to the throttle area on the receiver it works perfect but then I do not get the throttle to work in any of the receiver plug in entrance points. I know there is a way to have this work with what I have but I am missing something and do not know what. At this point I am spinning in circles to figure it out. I thought also that maybe I need to reset one of the settings in the transmitter for either the pitch or the throttle to get them to work with the pitch of the swash going up or down with out moving everything else one way or another. I was and am just looking for the simple settings for the receiver hook up for the DX6I Transmitter and the if I need to re-program the transmitter a different way than I had it for my electric Heli's? If you can help me out on this in any way I would greatly appreciate it or if you could send me to a link that will show me what to do etc. thanks for your time and hope you can help me before I take out the shotgun--LOL. That said thanks.

It would really help if you told us what helicopter. servos etc.?
Genesis Hobby (Pantera heli mfg) has what appear to be some nice servos. Good torque and speed and around $55 each.

Just a caution here.
IMHO, the most important spec on any servo would be the % failure rate within the first 10 hours of use. Lower relative specs (with in reason) in other areas will not cause a heli to crash, but a servo failure will.
Unfortunately no manufacturer gives these specs. That is why I have always stuck with top brand name servos that have a well proven and documented reliability history.
I do not believe in using a servo that "appears to be nice". I want them to be proven to be nice and dependable, over a good period of time (200 plus flights) by a relatively large number of users.

Excellent point, but it's like trying to get a job without experience. The ol' catch 22:lol:
