|Thread: Revolver Pusher type Autogyro trainer|
I have just been trying to get the motor off-set by susspending the model from the pylon and running the motor,. The motor turns anti-clockwise ( When viewed from the rear), leading edge to the front. BUT the motor is now on the left . I am using a master airscrew,( MA.3B09x70R01) 3 blade 9x7 R/P. Have I got a blade with the wrong characteristics??? Does the 'R/P' mean the wrong rotation or some thing else. Please excuse my ignorance as I am an old returnee and things have moved on a pace. Can anyone throw some light on this please . Other than that I THINK I may be almost there!!!!!
Edit I think I have just twigged why, as the motor turns anti-clock and not clockwise. R/P means reverse thrust. Steep learnibg curve, another lesson learned. Hope it will still perform OK.

Rich,is there a specific reason why the rotor blades are designed to revolve in the direction they are, other than the orientation of the aerofoil profile.? For instance if the profile were reversed would the blades go in the other direction.?
Or should I not get involved with the science!!!!!
Steve, I measured the travel with one of those servo testers!!!!!. I assume then that this is not reflective of the travel experienced when using a TX??( Older person returned to hobby after many years, trying to catch up on everything, but learning fast, also not afraid to look an idiot, wether I am or not !!!!!!!!) That's me. I am waiting for comment by Richard before taking the plunge and cutting away the front of the mast support/fuc'ge .
Richard, forgive me for what seems such a simple question to an expert like yourself but........
I am trying to cut out the hole/slot in the rear cabin cover for the control rods from servo to the head. I am using the same servo as yourself. They servo arm has a travel of some 135 degs, This amount of travel would require an enormous slot to allow full travel of the servo arm. I have examined the pics on the post , and the slots seem quite small. Is it possible to show a shot of the slot or more and perhaps some guidence for a long in the tooth novice lilke myself. I've got this far and don't want to make a big boo boo and have to make another fuse'g.
Many thanks Barry
Hi, the article says prop is 8x7.5. It is illustrated as 3 blades. On this site I have seen many pictures/vids that are 2 bladed!. What is the size recommended for the D3530/14 motor and how many blades please. Being a returnee I have a lot to learn.
Regarding the balancing of the main rotor blades.
You recommend using Balsaloc , I assume this is to add weight in the right place!!. What else can be used as my local model shop has indicated that this type of product is not widely used. What type of product is acceptable for same purpose, assuming it will be covered at some point? As is glaringly obvious I have every thing to learn about modern covering types and techniques so please bare with me.
So many questions, sorry to be such a pain .

Hi, sorry but I forgot to say that I tried a Tower pro SG92R that's 14mm min from the ply support to the top of the arm.barry
Hi, I have returned to modelling after a long break, decided to make Revolver!!!!.
I have a problem in the selection of the rudder servo!!. There is limited room and the one I bought does not fit, to tall .
hacked things about, the only way is to mount from under the ply mount cutting away the 6mm balsa floor, I am not happy with this. Could you tell us which one you used, so I would be sure it fitted please. Also puzzled hoe you would get the push/pull lines in after closure!!!
PS Love the model I hope I can get it to fly Thanks
