Where did you get the cylinder heads?My Simple Cub is getting close to a maiden! Yay!

I put the wire in the servo arm hole that is the same distance from the pivot point as the hole in the control horn to the hinge.
I moved mine so I could achieve the throw gauge movement for low rate with the amount of movement provided by the servo. I think I used the middle hole as well. My plan (if I ever find a minute to finish the ailerons) is to set the low deflection up as the regular rate and cut back 20% for the low rate while I'm getting used to the airplane. I'm admittedly not much of a pilot so I throw caution at everything.Hey, I've been watching the vids for a couple of years now, and I finally jumped in and bought the Simple Cub. This is my first foam board build. I have a question, and I have searched for it, but been unable to find an answer.
In the build video, Josh uses the shortest arms for the servos with only 1 hole when centering them. Later in the vid when he is installing them, he puts the control wire in the middle holes on the servo arms. So my question is, which one's are correct? Thanks for your help.
I've seen lots of landings that nosed over. I'm using 1.5M Timber wheels and plan to mount them about 1.5" forward of the normal position for rough fields (all I fly from really).FT SIMPLE CUB MAIDEN
I'm in the process of learning by destruction with my Cub (#2 is already on the bench). I have the timber tires and built the steerable tailwheel with modeling plywood (just cut it to fit the taper with the hole aligned at the rudder pivot point, doubled the ply where the wire goes through to 1/4", and hot glued the wire to the rudder - so it goes rudder, plywood mount, trails about 1.5" and wheel) and I mounted the front wheels using the original wire and slot, but using plywood on both sides the wire. For Cub part deux, I'm going to make a slotted plywood sandwich of sorts to mount the gear wire in. The plan is to cut two 1/8" sections that fit the current gear slot and pieces of plywood 1/4" wide and the length of the slot (tapered at the bottom where the landing gear wire comes out). That gets epoxied together to form the gear mount and then gets mounted in the fuselage slot. I'll bend the landing gear wire so the outside of the wire fits inside the hole created by the 1/8"x1/4" spacers and extends 1/16" above the top of the plywood mount. Once the wire is inserted, I'd zip tie the gear wire in the plane just to hold it in. That way if the gear wire needs repair or replacement I can cut a zip tie and pull it. On my current Cub I bent the wire slightly forward to save props during grass field landings. That seems to make it balance better too.That has been my experience as well and like you have been upping the wheel diameter to accommodate bumpy fields. Had not though about Timber tires but will give that a try this season. I have also had issues with the landing gear mount. I like the plane well enough to build another, but this time I will use to ply reinforcement around the gear slot and use 3d printed gear mounting instead of the foam board. Btw, Nice paint scheme.
Did you seal the foam edges of your Cub before painting (with hot glue) or just poly and paint?Next up is the Dr1 mighty mini triplane almost finished and the mighty mini corsair I just started. Getting lots of rain here in NC< so more time to build! I enjoy building more than flying View attachment 104660 View attachment 104661
I mounted mine alongside the inside of the fuselage with self-adhesive velcro. You can place it on the power pod as well (behind the ESC).
Sure. Don't know what your previous flying experience is, but the Simple Cub (with standard control throws) can be a handful at first. If you're using it as a trainer you can dial down the ailerons and rudder for the first couple flights (I think my ailerons are 1/2 the low gauge setting) to make it more "cub-like". I plan on using expo settings at some point and adding flaperons into the mix (about 1/2 flap) for landing. I don't need any help with take-offs, with the B pack motor, a 9x4.7 ARES prop and 1000mah battery this thing can take off in a couple of feet on grass (I'm using Timber 1.5M wheels).Thanks for the help.
