iflyforfunYeah, i haven't been on the forum much lately, really been flat out with uni work. Nods @ dillzio mount :-D @ging My cub ended up tail heavy after I covered it with the profilm, apparently it's not an uncommon problem for people that cover their cubs. I tried to minimise the issue by not profilming the tail, but I did end up using extra on the back of the fuselage. Because it isn't as wide back there, the pieces of film that did that area all had enough overhang to wrap around and do half of the next side, so the back bit of the fuse basically has a double layer of profilm on it. It threw off the balance a bit, but it does make the fuse way stronger. My whole plane is a tank! scottdid you also copy the ailerons and flattening out the wing with carbon spars so you can fly it without struts? With the three CF spars (1m longx3mmx.75mm) the wing is unbendable! I've seen the cub get tossed around in winds that could snap an original cub wing if flown without struts, and the wing really is as solid as a rock! I really like the 35-30, but to be perfectly honest I can imagine having a bit more power. If you want to fly it like a true plane, like a scale one that actually has to be moving forwards to stay airbourne, then the 35-30 is perfect, but i'd like to have enough power for hovering or unlimited vertical. I think the 35-36 would be a good cub motor, not sure I'd want anything bigger though. I flew mine last night with a MAS 9x7 prop at 20amps and I still wasn't overly impressed with the power. I mean it crapped all over a stock cub, but i was hoping that it'd be able to climb at about 45 degrees, and it can't :-(. Perhaps i'm just expecting too much from the humble little super cub? In more unforunate news, i lost the back underside panal off my cub. You can see it in my videos of the finished plane, the yellow panel (that has the 3 holes in it) with a slot cut into it for the navlights and with the cool hobbyzone sticker on it - it came off about 30m up 300m away and was never seen or heard from again. I did make a replacement though out of fluteboard (correx) - I knew that stuff would come in handy for something! You can see the base of in in the pics i've just posted. thanks for the feedback fellas!

Dillizio, Im sure you have been reading my post over the past couple of months about how I wanted to mount a 35-36C. Every time I mentioned it I received posts about how overpowered, too heavy and all the problems such a motor in a cub would cause. My reasoning was, the calculations from wing loading to flight characteristics told me it would work and not only work but be a great flyer with the Super Cub appearance. I have always takin the approach that you can never have too much power as long as you are willing and able to deal with the flight characteristics. But like I just said, every calculation said it would fly good. I took my cub out to the park near my hotel here in Detroit and had my maiden flight with the 35-36C. Holly S.................t, Dill, you have got to order one and get it in your Cub as soon as possible. Unlimited vertical is more of an understatement. It jumps off the ground in about 6 feet. It becomes a speck in the sky at about 30 seconds. Dill, I am not kidding when I say it's a rocket. Now I have a heavy plane. I would bet it's one of the heaviest SC around because of all the mods I've done. Flaps,Ailerons,extreme battery box conversion, extra wide landing gear from float kit, huge 5amp BEC to power all the servos and that monster 35-36C out front. O ya, a few grams of packing tape on the underside of the wing to take all the dihedral out. My super Cub is pushing 35 OZ right now. Is it overpowered....NO WAY!!!!! It flys fantastic and just like a stock SC trimmed at 35% power. I flew with a TP 11x5.5 prop and was pulling 31.8 amps and 380 watts with a Turnigy 2200 20C lipo. I got a little trigger happy with the first battery and really pushed the plane,motor and battery to the limits and after landing the battery was hot. I stuck my little voltage meter board that I got from HURC and took a reading and all 3cells were at about 2.8 volts. Not good for the battery( most likely junk now) I'll have to keep an eye on it. I had originally subtracted 15% off the battery for overrating and came up with a supply of 36amps on the safe side but that is obviously not enough. I am thinking of using my 2200 and a 1300 together on a y harness. That should give 3500mah minus 20% for overrating brings it to 2800mah @ 20c. That combo (2.8 x 20 = 56amps) should easily supply what the 35-36 needs without over stressing the batteries. Back to how she flys, like I said I trimmed it for 35% power level flight and she flew slow and beautiful like a stock cub. She wanted to drop more in a turn than a stock cub but I just adjusted with a little more up elevator when entering a turn. Inverted flight was just as easy as regular flight and I think the biggest reason is the amount of air that huge prop is throwing over the elevator. When flying straight and level any small adjustment on the throttle gave a huge reaction with pitch. I tried to hover a few times and found it very difficult. There was more than enough power but I don't think the rudder has enough authority. Even with all the thrust from the prop I could not get more that a 3 or 4 second hover. She would start to tilt and I would just give WOT and she would just shoot straight up out of the attempted hover. Landing was another thing all together. I have flaps and I had to jump it up to 40% down elevator when I hit the flap switch. This can only be the result of that huge prop. With my stock cub and later with the alpha 480 brushless I only needed 20 % down elevator. Landing with the flaps was very slow. Slower that a stock cub without flaps. But I did need to keep a little power in to stop from hitting that huge prop. The first 2 times I did power off landing with flaps deployed and it was very slow on touchdown but I had no more elevator authority and could not flare. The prop hit the first 2 times. Then I started using just a touch of power and that's all it took. Perfect landings with no head wind and extremely slow. I tried landing without flaps and did not like it. Very fast. It would not be a problem at my normal flying field because of the room I have there, but today I was using a baseball diamond with a huge fence behind home plate. I still got a couple of landings in without flaps but needed a long approach and had to use lots of trim to slow her down and I was not happy with how she felt on approach. Almost like on the edge of a stall. I new from my original calculations that she would have a high landing speed without flaps and now I'm happy that I did that mod. I did some high speed WOT runs and she is very fast. No doubt that if you throw full up or down elevator at that speed you will BE PICKING UP LITTLE PIECES OFF THE FIELD. So to sum it all up. If you want a HZ Super Cub look and also want some blazing performance the 35-36C is the ticket. If you like to take pictures from 1500 feet and want to get up to that altitude in 30 seconds cut the power to 35% and float around for 10 minutes the 35-36C is the ticket. If you want to fly inverted low to the ground then just go WOT from inverted to unlimited vertical then the 35-36C is the ticket.( I did that today but started at about 100feet) I bought this 35-36C for my Multiplex Fun Cub!! Now I have to order another one because there is no way I'm takin it out of my SC. Dillz, I'll be back in New Jersey this weekend and if the weather plays along I will try to get some video shot and edited before I leave for Germany on Tuesday. You will not be disappointed if you mount the 35-36C as long as you don't try any sudden crazy maneuvers at WOT. Ifly |

Perhaps i'm just expecting too much from the humble little super cub? thanks for the feedback fellas! I haven't flattened the wing out yet as you did but plan to. Yes I did do my ailerons similar to yours. made them 12" x 1.75" and put them on with tape. Although I did use the double bevel method because I was going to use hinges at first. After a lot of thought I finally decided to tape them on. I am very pleased with the results. I did not do flaps though. I was able to easily program the ailerons to work like flaps on my turnigy 9x. As far as the 35-30 goes I like it but I think the 35-36 would actually be a better fit for the SC. I believe it would be closer to the weight of the stock motor and mount (maybe a bit heavier) and you wouldn't have to use washers to space the prop out to clear the cowl like you do with the 35-30. Some might say it's too much motor but if you are like me you don't go WOT except to show off for about 10 - 30 seconds at a time. Most of the time I cruise around at about 1/2 throttle. Overall review of the 3530: Excellent upgrade with plenty of power for normal flight and most maneuvers. Does not have the "wow!" factor, but a lot better than stock motor. Good flight times. |

Hi gang, got some tragic news. Very sad indeed, particularly for the person that happened to build my cub. I've lost yet another cub  . I guess I must have gotten a bit overconfident; since building my new plane I haven't had a single problem with it (other than my elevator reversal problem that occured on my very first flight). I've had some excellent recoveries from aerobatic manouvers such as inverted loops that didn't quite work, and haven't had a single crash or ended up in a tree. I guess the time I spent on the simulator must have paid off. I flew it the day before yesterday, and due to my overconfidence, I didn't pay much attention at all to which way the wind was blowing. I flew it in near gale force winds at Pt Gawler a week or so ago, so I felt that wind wasn't really a big problem for this particular cub. Anyway, I ended up flying it downwind, and it just got away from me. I tried to bring it back, but by the time I worked out I was in trouble it was too far away for me to tell if it was facing towards me or away from me, so I couldn't get it back. Pity I wasn't flying at night, with my navlights it would have been easy to tell which way it was facing. The plane started circling and loosing altitude, and at that point I realised that it was a gonner so I cut the throttle. I had a fairly good idea of where it went down, but it was in a suburban area over houses, so it probably ended up on someone's roof or in their backyard. Me and a mate of mine walked around where we thought it went down, looking for it's flashing lights and listening for it beeping, but to no avail. We couldn't work out why we couldn't find it with the flashing lights while it was beeping - it seems to us that either the electronics got too badly busted up on the crash landing, it landed in a swimming pool, or someone found it and took out the battery. The worst part of all is that due to my foolish overconfidence, I decided NOT to fly with the GPS tracker so that the plane would be lighter and more acrobatic. My only hope now is that someone finds it and calls me, as my name and phone number are labelled on the plane (thankfully!). OK ppl, I'm ready to be berated now... Ah the ignominy of it all!  |

I saw a video of someone losing a SC in the same way. They immediately flew another SC with a camera onboard pointing straight-down over the area in a sweeping fashion. They got home and analized the video and found it near a highway! They then proceeded to go get it and there it was. You should have done the same and you should have kept the d**n GPS tracker on it, man. In any case, I'm sorry for you and good luck... also,  |

Gnnnnnnnnn, sorry to hear that Dill what a bummer, had any thoughts on the future of super cubbing? Bit of a bad week for casualties all in all, what with Toffs bad day too.

Aww, jeez Dill, I'm really sorry for you man! Fingers crossed that you manage to get it back. If not, you 'll have to get another! This place wouldn't be the same without your input!  |

That is really a sad story. You put so much time and effort into that plane too.
Hope it shows back up. Let us know.

Hey Dill,
Sorry to hear about the loss. Let's hope that someone finds it and there is a good end to this.

Thanks for all the support guys, you're a really great bunch here at the super cub club. I've put up some LOST posters at the local shops so there's still some hope. I'll be sure to let you know if I get it back.

Ive been gone for a few months, and reading up on what I've missed turned into something of an Epic. A triumph over time and success with lights and flight, but then a tragic flaw brings down the hero auzzie dude...
Im hoping that you get it back.
If you don't, would you ever think of moving on to something less effected by wind?
Or are you dedicated to the excellence that is the super cub?

AMAZING NEWS GUYS, I GOT THE CUB BACK!!
I got a phone call from a guy that saw the lost poster I put up at the local shops. The plane landed in a tree in his yard, then fell down a couple of days later. The guy that found it didn't even see my name and phone number written on the plane.
The fuselage and motor are fine, but the tail and wing have seen better days. The tail got bent up pretty bad and probably needs to be replaced. The wing got pushed off centre so that the rubber bands were gripping to the side of the plastic protector, so the bands dug into the foam and warped it a bit, and the wing seems to be kind of warped and bend in the opposite way to the normal dehedraled. I guess all the carbon fiber I put in it didn't work quite as well as I'd hoped.
I'll probably try to mend the wing if I can, considering how much effort went into the CF reinforcement, navlights and profilm i'm not in a rush to have to do it all again. Unfortunately i'm flat out at the moment with uni and exam revision, but at least I'll have something to keep myself entertained during my break period :-)
