    Scale RCM 1/3 Scale Champ Build

    I'm thinking my next build will be a R10 PRO with two R4 receivers in trio mode. Assuming it is less than 10 channels.

    Rick, Have you given any thought to the R10 PRO? Dual XT-30 plugs.

    Scale RCM 1/3 Scale Champ Build

    The batteries are mounted under the front seat along with the ZEPSUS switches. The switches have a 15 amp rating as well as a burst rating of greater than 30 amps and tested at 20 amps for 30 seconds. I'm pretty sure two will get the job done, heck there's only 4 D945 servos on the surfaces...

    Scale RCM 1/3 Scale Champ Build

    I made revisions to the mounting angle and position of the sticks based on photos I found while researching the throttle plates. I did find the throttle plate photos on Ebay and working with someone to CNC engrave two to mount under the throttle knobs. Based on the original running of the...

    Scale RCM 1/3 Scale Champ Build

    I used the tin from an empty gallon can of WD40 to make the straps for the seat backs and had some left over so that's what I used to make the control rod mounts. Since it is covered with the boot there was no need to sand the printing off the tin. As I worked with the printed metal it took me...

    Scale RCM 1/3 Scale Champ Build

    From the Roto website; Crank case (kit) – it is rough-worked of the cast at the CNC milling cutter. After that it is covered or slashed with a special colour. Cylinder (roll) – it is made of one piece of dural with pressed insole from the mild-granular cast iron, it is sharpened and honed to...

    Now that the CH Ignition will be installed this will free up two temperature sensors, have any idea where to place them and what an alarm might be? I used 290f on the cylinder based on 2 stroke experience but I don't know if that carries over? On the head the intake is on one side while the...

    Scale RCM 1/3 Scale Champ Build

    True story, Yesterday I ran the engine with the cowl on, ran it at less than 1/4 throttle until the temperature quit increasing. The cylinders were approximately 260-270 f, both temperatures on ignition module slowly increased to 132f at which point the engine began to miss. Shut it down and...

    Scale RCM 1/3 Scale Champ Build

    Found the control stick cover for sale online, I made mine from the same material that I covered the dash with. Thought I could just use fabric glue to assemble but had to get out the needle and thread and put three stitches in the seam. I think I going leave the stick natural aluminum...

    Scale RCM 1/3 Scale Champ Build

    Control sticks, I purchased the white stick in the photo below from I Fly Tallies, it is a little short for the Champ and I thought it shoud be a little larger in diameter based on the photo below. For reference the same gauges are 20mm 1/3 scale so I estimated the control stick diameter to be...

    Scale RCM 1/3 Scale Champ Build

    Looks like the 85 will fit inside the cowl, once the Champ is finished up I'll study the Super Cub and determine what I'm doing, petty sure I will parting with the 3w 56 CS.

    Scale RCM 1/3 Scale Champ Build

    I did find that Johnson mufflers were sold by AI, they have 1 muffler listed. On another search I found that they are out of business and this guys mufflers for the 56 twin were leaking. It has been a while since I looked at them but from what I remember the mufflers were nice, they are little...

    I cut the tubes off and made a single scale like exhaust. I believe the mufflers were Johnson brand? Pretty sure they came from AI.

    Scale RCM 1/3 Scale Champ Build

    When I purchased the engine some time ago there was some discussion about hesitation with the 4 strokes and the need of an electric fuel pump. Everything works as intended on the Roto from I can tell so far. The fuel tank is about 4" below the carb, after choking and flipping I pulled the fuel...

    Scale RCM 1/3 Scale Champ Build

    I do like it, I'm thinking I might just finish off that Super Cub with one. The plane was built using a 3W 56 CS engine, never ran, just might sell it and buy another Roto 85. Need to check the cowl size, the 3W fit in just fine. Back to work on the Champ, enough of this playing around with...

    Check it out . I don't know, wonder what a reasonable cylinder head temp might be? Easy to change if need be. I emailed Roto and got no response some time ago.

    Scale RCM 1/3 Scale Champ Build

    Before painting the fuselage the weight 36 pounds and the CG was 6 5/8"back from leading edge. Weighted the finished plane today and it came in at 39.8 pounds and the CG is now 6 3/4" behind the leading edge, this results in a static margin of 6%, I'm good with it. Based on the weight an wing...

    Spent the better part of the day messing with telemetry. I want to measure three temperatures, each cylinder and the ignition module, According to the instructions the ignition shuts down at 140F, wonder who came up with that scheme? Every device I came across does 2 temperatures. I found...
