Status: offline 		I am building a Royal Cessna Skymaster and have a few questions and something I am looking for.

I have a complete kit minus the main landing gear. Does anyone have a one they didn't use or know where I can find one?

I just started the kit. Can anyone offer any hints concerning:

1. Servo location and number of servos
2. How to set up the control linkages and throws
3. Engine selection
4. Fuel system
5. Mufflers
6. Anything else that could help.

Status: offline 		i assume u mean the maritaka kit, which i am building now. haven't finished it but ...

intend to use (2) OS .70 4S engines

i cut flaps per the plan and am operating them with one central servo and bellcranks

the ailerons i put a servo out under each wing

the rudders will use the connecting rod thru the horiz stab (per plan) with the servo mounted on the inside of the tail boom

the elevator will use one servo mounted on the inside of the other tail boom. by inside i mean the inside surface, not actually inside the boom ( no room).

the engines will each have a mini servo set up with a program mix in the computer radio

lastly, i have to install a servo to steer the front wheel which will be Y conntected with the rudder servo

The $10 servo killed the bell crank. :P

Status: offline 		the $10 servo killed the bellcrank may be true but when you start driving one bellcrank with another bellcrank alot of slop develops plus the adjustment process is quicker with individual servos.we have the capabillity to improve an old design for better flight performance so why not bring it up too todays standards?

Status: offline 		Thanks for the reponses. I am in the process of building the fuse and started the tail booms. TNT landing gear did a great job making the main gear to order for me. I will also be using four low profile aileron servos two for aileron and two the flaps. I would like to use two aluminum spinners but I am having a hard time finding one for the pusher prop, any ideas where I can find one?

Status: offline 		I would think that the standard spinner slots would work with pusher props. Becarful of wich direction the prop is faceing. On most of the pusher props that I have seen the words are on the side of the prop that faces to the front of the airplane. So if your in the back putting it on, it will look like your putting it on backwards with the words away from you.

I too am building the Marutaka Cessna Skymaster 336. I cut my flaps out on the lines indicated in the plans. I plan on using individual servos for everything. No bellcranks.

Which kit are you building?

Anthony

Status: offline 		If you use a plastic spinner with the conical cuts in them or one of the "wide blade" aluminum spinners, then yes, you could probably use a regular spinner. However, if you want to use a slotted aluminum spinner, the slots are slanted different on a pusher spinner. As mentioned above, Tru-Turn will cut one for you.

Status: offline 		I've got the old Royal version of this kit, which someone started several years ago and gave to me. They put the front engine bearers on the wrong side of the plane. I'm guessing the firewall is in upside down. Don't have the fuse to look at here at work. Anybody take a guess at a work-around on this? I would love to get it flying.

Cut the wood engine beams off flush and use a metal or fiber radial engine mount. You may have to shim the engine mounts to get the length correct.
