Servo selection
K I am trying to put together a yellow f18 single, and need advice on servo selection.
We currently have a JR X-3810 Controller and a PCM S 36MHz reciever. We also have 2 DS811 Servos Spare from another build.
THe kit needs
2 rudder servos
2 stab servos
1 throttle servos
1 nose gear servo
1 retract servo
Could somone please suggest which jr servos are suitable for this aircraft and if possible if the DS811 servos are suitable for this application
kind regards
Nick

RE: Servo selection
No torque ratings in instructions, and yes im a beginner, and yes ive heard i shouldnt start with a jet, but hey thats what ive got so i need to try and build it, so if someone has a useful reply it would be appreciated

RE: Servo selection
I haven't been flying long but please keep me informed as to your planes longevity.
I have seen guys with 25+ years of flying pattern/bipes/etc, crash multipule F-86
foamie ducted-fans because of the flight characteristic differences. So even if you
do get the hang of a fast mover, I don't think it will be the same as slower fixed
wing aircraft. At any rate, best of luck.

RE: Servo selection
schematic - I assume that you are going to continue with this poor idea of flying this plane so here is a suggestion to try and get as least a couple of flights out of it.
1. Find someone who is qualified to fly this type of plane and an instructor preferably.
2. Let him go over the plane when finished and do the maiden flight for you.
3. Have him set it up with a "buddy-box" arrangement.
4. Don't fly it yourself unless the 3 conditions above have been met or you will not have a plane within a few seconds. You are investing a lot of time and money, don't you want the truth? This is FAR-FAR-FAR from a beginners plane.
Good luck.

RE: Servo selection
Prophanger, was hoping you would confirm the servo's i was thinking about but you have gone a differerent option then i would consider. So far what i was thinking was JR 331 micro for throttle, isnt the 811 a bit of an overkill for a throttle controll in terms of weight, and torque, also was considering DS9411 for the aileron/taileron configeration. The DS9411 has about 10% less torque than the 8231 but is does make up for this in weight reductions which at the moment are vital due to other equipment the aircraft must hold. If there is any strong reasoning why these are not suitable please let me know, also cost is not a consideration vs the cost of what the aircraft is carrying

RE: Servo selection
While i am a complete beginner in terms of building this type of aircraft (jets), flying should not be a problem as for the first 30 hours will be fixed flight in the wind tunnel, after this we will be using a experienced jet model pilot used to the F18 control, and hopefully eventually flick over to UAV control. So far I have found these forums to spend more time trying to detract people from building rather then trying to support them through build issues. Just because people are beginners in these areas does not mean they have some basic common sense in operating these aircraft. I also find here that no one is eager to make the transition from fixed wing trainers to jets. Sure jets are hard to fly and jets crash hard but that is life, you have to make the change some time.

RE: Servo selection
There is an "RC Jets" forum on RCU. I'd post the servo question there in case someone has built this plane and knows what it really needs. A lot of the people who build and fly jets may not read the beginner forum very often. As a novice I know I've never looked in the Jets forum.
If you've never flown RC planes before I'd definitely suggest getting a beginner plane of some sort and learn to fly it while you're working on the jet. You might find a good deal on a used setup that doesn't need any building.
<<< edit >>> Just noticed your post about the wind tunnel, etc. That happens to be the first info you've provided that indicates you're not a total beginner who plans to learn to fly RC aircraft using a jet.

RE: Servo selection
do you have a link to the airplane....?
I would love to see it..
and does the "experienced" person have RC experience or real jet experience??

Your goal, now that you have finally explained it, is different. If you had said what you were doing, up front, the people reading your post would have understood your goals, and you most likely would have received different answers.
Based on your goals, this thread actually would be much better suited in a Jet forum, where the people who participate have more experience with the questions you are asking. The typical airplanes discussed in this forum are high wing trainers and other planes that would be suitable for a person's second or third. Discussions about more advanced planes typically take place in other forums.

Schematic, this is a "Beginner's" forum. It is used by people who want to learn to fly radio control ariplanes. It is very common for someone to have just seen some cool jet and decide they want to emulate Maverick and be the next top gun with an R/C jet. When these people first post on this forum many of us invest our time helping them understand that they may need to start a bit smaller, and slower. We do this not to be difficult, but to help these people suceed. Helping a person who has never built or flown an R/C plane build a jet is a waste of time because they WILL destroy it.

Schematic - Coming into the forum and only giving 1/2 of the story is a great way to receive incorrect assistance. Had you fully explained your position and intentions, my reply (if any) would have different. As for transitioning from trainers to F-18's, even the military starts out slower than that. They start with a primary flight trainer, simulators, advanced trainers, dual seat trainers and more. You certainly have the right to drill any plane you wish into the ground and I wish you much success in doing so. Enjoy!
