Hello all! I was looking around for a new hobby the past couple of months and came across RC flying. After doing my research, I purchased the Super Cub and then found this forum, both of which are awesome! As a noob I am looking to give my cub a complete overhaul to make it more "noob-proof." I'm still working on completing successful flights...  . I am looking for any suggestions that will make my Cub stronger and better, as well as faster and have better performance. Any improvements are welcome: props, landing gear, batteries, body reinforcements, anything that will make my cub better! Thanks for all your help! |

Change the batt to a 3 cell 1300 mAh lipo 20C Most that size will just fit in the batt box , might be a tight squezze but it should go & change the prop to a 10X6DDto keep the amp draw down, be sure to pull the jumper out of the Rx located where the ACT plugs in when you are using lipo batt .

My best suggestion is to spend a week or two reading all of the posts. Essentially your question will be answered in them. Best of luck! |

I say get to know the controls before worrying about speed. Crashing is better off when slow.

Thanks for all the help guys. Do you all happen to know any weak points on the cub that could use some reinforcing to make them more crash-proof and if so, how? I already had a servo break loose and I had to reglue it using Gorilla Glue, and now my rudder is maybe 5 degrees to the left with full right trim. How would I get that back into line?

Take the arm off the servo , turn on the TX plug in the batt , center the rudder trim, center the rudder and reinstasll the arm , putting it as close to pointing stright out from the side of servo as you can and still have rudder centered ,tighten it down and you should be good to go.

I have to add that once the trim is centered, if your servos arm is 90'd (which it should be if you never took it off) then simply look at the end of the pushrod at the rudder horn. You will see the plastic end is threaded on the rod. Disconnect it and screw it inn or out whichever it needs to align it properly. Chances are you wont need to take the servo arm off at all. Just use the rod threads to adjust it.

But when I try to adjust the clevis on the rudder the adjustments will only pull it furthur left, when I need it to move right. What is the TX and RX you guys are talking about? Sorry, I'm really new to this..  |

TX = Transmitter RX= Receiver
You said you had servo come loose and had reglued it , that why I had said try and adj by re alinging the servo arm. Is the servo moving the rudder ? Could you have striped a gear in the servo ? Is the arm of the servo pointing 90 deg to the body of servo ?( It should ) Hope this helps keep us posted

Yea the servo moves the rudder fine, so I don't think that the gear is a problem. The servo arm is pretty close to 90'd. Should I remove the arm and change the position in the arm to try and readjust the rudder?
Thanks!

Ok so I just looked at the rudder horns with my glasses on and I did realize that they are threaded, as memugen said. I twisted it out to the left with my trim centered so now I have the rudder at 0'd with full trim available. Thanks for the walkthrough guys!
I also placed an order this morning for some 3" Dubro superlites and a 1" Dubro tailwheel. Will these fit spot on or will I need to make some modifications? I also picked up a GWS 10X6 prop, which I read performs well on the cub. It was too windy to fly today though, so I haven't used it yet.
Besides the wheels and prop, any other suggestions about cub improvements? I noticed that my prop (after looking at the motor and gearbox with the cowl off) spins down, as in the shaft is bent. Is that normal or damage from one of my crashes? Also, how important is prop balancing?
Thanks for all the help again!

If your shaft is bent replace it asap. It will fly....but for how long? Balance is not a huge deal on these but I do it anyway. Nothing like a trued prop turning....no sound from vibrations.
You can add a strip of packing tape to the leading edge of the wing for sticks and such when landing in rough areas....or just landing in trees...haha.
As a general rule and just to get into good habbits I balance all props for both electrics and gas.

So it is a bent shaft it's not turned down for torque or something? Ok well I picked up a new one anyway so maybe I should put it on for safe measure, or at the least I can compare the two. Are prop shafts bent often? I had a pretty nasty nose-first crash....
Do I just remove the gearbox to change the prop shaft?

Oh ....I see now. You mean the thrust angle. Yes that is supposed to be that way. If you turn your prop by hand and look at the center of the end of the shaft, does it turn true?

Yes with the prop off it spins straight but when the prop is on it looks as if one end comes closer to the cowl as it rotates, but it could just be an optical illusion.
