Thanks for your concern Ging,  I'm not new to RC,just new to Electric RC. Actually I did'nt know a dam thing about ERC till I decided to start upgrading my Cub. For the past few months i've been satisfied with plugging in the battery and off I go. Right now I fly a Sukhoi SU-26 XP. Take your eyes off for a second and you'll be in deep s...t! When I got back into RC a few months ago I started out with the HZ Champ. Get that up in the air and you could read a book while flying ;D I need to learn ERC in and out. I thought the Super Cub would be a good platform for experimentation(motors,esc,bec,batteries). I think it is a superb trainer( yet I would never recommend it as a teach yourself to fly plane like they advertise)It has turned out to be much more fun to fly than the Sukhoi. If you want to have a nice slow flyer like the Cub to do some aerobatics that look half decent, you have to take the dihedral out and add ailerons. Have you ever flown off floats? If not, it is awesome. |

I just thought I'd update regarding the CG corrections for my plane, when I said it only needed 1 oz on the front that wasn't entirely accurate, I also have my GPS tracker mounted towards the front of the fuselage to add some more weight to the nose.

Hi Dill, have you tested the GPS tracker and what were your results? Are you happy with it. I am also thinking of something like that. With all my mods and new receiver I got a few hundred dollars flying around. I think I need to invest in something.

I got tired of waiting for the stock ESC/RX to come in so I took the esc and motor out of my grounded PZ Corsair...I mounted it, using the Corsair motor mount, which took some drilling of screw holes, but nothing major. I used the servos from my corsair and an AR6100e RX. It flies wonderfully.

I've just ordered the Turnigy 35-30C-1100kv motor for my SC build from parts that I bought over two years ago. I'll be using a new spare CC Thunderbird 36 ESC. Sure hope I made the right motor choice!

Sure hope I made the right motor choice! Aeromite IMHO, I think the 35-30C is a great motor. I dont have as much time on it as other members but the little bit that I flew my cub with that motor was a fantastic experience. If you are going from a stock setup to the 35-30C you will be grinning from ear to ear on your maiden flight. I'm not familiar with the Thunderbird 36 ESC, but if the 36 means it is rated for 36amps then you will be fine flying with the 35-30C. Good luck and keep me posted!! Ifly |

Sure hope I made the right motor choice! Aeromite I have the 35-30C 1100kv on my cub. It's like going from a wagon wheel to a wheel with ball bearings! Very smooth and quiet compared to stock. Excellent power but not burning fast. Good flight times. 30 Amp ESC is adequete so a 36A should be more than adequete. I also bought the engine mount off ebay for $20 which is specially made for the 35-36 sized motors to mount to Super Cubs (glad I did BTW). Because it is made for the 35-36 which is a longer motor, using this mount you will need to use an extra washer on the prop shaft so that your prop clears the cowl. The 35-30C is an excellent upgrade! You made a fine choice. |

Beautiful day to fly and no wind. So it was time to get the floats out.
The heaviest I have ever flown my Cub and let me tell you I had sweaty palms on this flight..45.1OZ Dam she was heavy with the floats.
That is almost double the stock weight.
I did some tests before heading out to the lake:
Turnigy 35-36c
11x5.5E prop
51 OZ Thrust
31 amps
388 watts
45.1 OZ Flying Weight
She broke suction and jumped off the water faster than the stock cub but heavy on the stick. She flew beautifully but I was very scared that any sudden control input would cause the wing to fail. So I just putted around at about 60% throttle. I had lots of room to set up for landing and after doing a few slow passes with the flaps extended got the feel for landing and set up. Here I come all confident and now my palms are no longer wet and guess what. I FLIPPED THE DAM THING AGAIN. I can't figure out what happened! It was slow, the perfect approach, the perfect angle of attack,everything was dam perfect and when she touched the water she just flipped nose down. I was stunned. I could not comprehend what happened. No wind, everything was perfect and now my beloved SC is 40 feet off shore and I have no way to get it. Forget about the embarrassment factor as the day was so nice about 50 people saw what happened. Now this was more like a super large pond and there are no boats are anything like that at this place. After standing there like an idiot for god knows how long I decided I would drive home and get a Air Mattress and use that as my rescue platform. I was home and back with the Queen Size mattress my 12 volt electric pump, MY WIFE, MY BROTHER IN LAW, AND THEY HAD THE F...ING VIDEO CAMERA WITH THEM.
Guys, believe me when I say that I have never been threw so many emotional states in such a short time. Here I am laying face down on a F....ing queen size air mattress trying to paddle and not get wet and my freaking arms won't reach the water, and every time I try to get closer to the edge in order to paddle I got WET. By this time my brother in law and wife were laughing so hard and I was cursing so much because I could not comprehend what they were finding so funny. UNTILL I GOT HOME, TOOK A NICE HOT SHOWER, MADE A NICE CUP OF HOT TEE AND WATCHED THE VIDEO.
Guys, I learned a couple of things today that are extremely important. And I blame the more experienced members of this forum for not informing me of these things ahead of time. ;D ;D ;D ;D ;D
Rules:
1. Always have a inflatable raft to rescue your plane!!!!! Queen size air mattresses
will bring unwanted attention.
2. Never go home and tell your wife or any family member you are attempting such a
rescue.
3. Make sure you hide the dam Video camera if you don't follow rule # 2.
4. If you don't listen to rule # 1 , then just go for a quick swim and none of the other
rules will apply.
After all the bad language( and that is most of the video) is edited out I will post it so as to help any other new float flyers not experience the humiliation I endured today. ;D
On the technical side of things, I think I may have given full down elevator at the moment of touchdown instead of up elevator to keep the nose up. I'm not really sure what happened but I can't find any other reason so I will attribute it to pilot error.
It's 3:15 am here in Germany and I just took my Turnigy 35-36C motor out of the oven where it has been baking for the past 6 hours.
None of my electronics got wet so I'm in a pretty good mood right now and if the weather is nice again tomorrow I will try again and hopefully have a better outcome.

That sucks! Just keep some fishing line with you and a weight on the end. I recovered my SC once like that. I never flipped it though ;D It ran out of battery on a bad Lipo.

Ifly I would think you know enough to keep the oven merely warm, yes? Too high a temp will demagnetize it. Personally I just pop the securing clip or collar off, open it up, blow it dry with a hair dryer (rinse first with rubbing alcohol if necessary), and re-lube the bearings. Assemble-Done. If you DO get the electronics wet, cut power and remove lipo ASAP. Rinse with rubbing alcohol to help remove water. Take a hair dryer to it for awhile. Then set aside for several days in a warm place. You may have to cut the shrink off the ESC as that contains the wet inside. I don't do floats/water but I know people put something called Corrosion-X (?) on things. I have drowned mine in large puddles a couple times so do have wet/crash experience. |

Your right on Fly, must be kept warm. Not sure how accurate the oven in my kitchen is so I set it to 50C (about 120F) to be on the safe side. I'll put new bearings in when I get back to my shop. I get them dirt cheap from my supplier and the quality is top of the line. The motors I repair in my shop are baked at 375F for 4 hours. This is the industry standard. On new rewinds we dip and bake the armature twice.(2 complete cycles). Of course I am not dealing with permanent magnets. The field coils are energized to create the magnetic poles. You really got me interested in sloping!!! Something I will definitely try. Ifly |
