HI Jack yes it is a bit complex an I dint think id get it all in but a little patience goes a long way an I had great fun triyin to to get the chopper to work an yes the motor in the tail is very tiny about 4mm wide by 6mm long an both motors are 3v workin from 12v system in the ship by R/C on an off an the nav lights were 12v as well an hopefully a seaking will be all wired up with its motors an nav leds an landing lights on this thread when I get up to that far thanks for lookin in cheersLooking good Chris. The Merlin setup looks a lot more complicated than I thought it would be. That must be one tiny motor and gearbox in the tail!?

HI Tony now I don't mean to offend you but I think you are over thinkin the idea of your workin ramp doors as in my opinion yours should be easyier to work than mine now here is my idea of how I think yours should work 1. YOUR RAMPS have the hinges at the bottom don't they ? 2. just fit a servo horne cut down to about one or two or three holes in it glued to about half way up the ramps you should only need one on each ramp an how long an heavy are your ramps as you should be able to make them fairly light with H BEAM STRENGHTENERS 3. drill a hole the size of a aircraft plastic pushrod normally about a quarter of an inch thick an REMEMBER they ARE FLEXIBLE with its outer cable 4. run this through into the hull where a servo can be fitted an screwed into place 5. on the servo horn you should fit a ball an socket joint you can get them from a model shop or maybe off ebay 6. just try you ramps up an down to find out the length of travel the ramps make from the time they open till it hit the ground an then I cant now say any more as I don't know how big your ramps are please mesure them for me then i'll have another think on this ok but if its about a foot of travel on the ramp doors then I think you will need to fit a rack gear in the hull as with rack gear you can get a foot of of travel but then you will need to do like I did in my Nimitz elevators to push up an down this is the easyiest I can exsplain it but then it gets complcatiated but first find out how much travel on the ramps are needed ?

HI Tony lookin forward to the email pics an a servo will run slow but if you want it to whinch your ramps up an down then just simply look on the servo bottom. There you will see four screws undo them but hold all the servo together as you withdraw the long screws then get a soldering iron an desolder the motor terminals from the pcb board an gently take it to bits makin carefull note of how the gears in the servo top are all fitted just find the stops on the top gear. An cut them off so that the gear will revolve around completely then put it all back togeather an it will then run off 5v to 6v to whinch you ramps up an down on a push an pull system wth steel wire hows that ?Hi Chris, I had a better read and study of how you have made your hanger doors, this will shock you I have done mine the same way, I will get some closer pics tonight and send them in an email to you, I could run a full length brass shaft the width of the ramp, my hinges are a smaller version to yours and out of plastic and used tooth pics for the shaft . I am still thinking about a servo, will it run slow enough and not too fast as what I am worried about, what voltage servos are you using .Busy day today I am cutting up the cross beams for the bridge and the arch end sections, nice day here, have to wait till the grass dries out form heavy dew, getting excited as the bridge will take shape.
