hangar 9 40 CUB arf+ power 46

[skydve76]

I can get one of these NIB for $200 with the 46 power motor, to me that seems like a really good deal. My wife learned how to fly a super cub, so I am thinking of this for her next craft (under a training cable of course).

Can someone answer some questions:
HS-82MG, good enough for this?
Does it have enough power to loop and roll fairly well, or is it a strain (on 4s)? I want her to be able to do some aerobatics.

How is the construction, is it sturdt enough to drag a wing on landing and survive? It looks like a ply frame with monocote, not sheated wings but just covered. is that right? Seems kinda weak for an 8 lb plane.

Would you say the flight characteristics are that of a super cub, of course with ailerons. In vid, it appears to be able to fly at walking speed.

Finally, flaperons, are teh effective? I use them on my large jets and they are quite effective, but I don't fly any other prop planes so wasn't sure.

I'm thinking a good second plane with my wife to train on, then she can go solo. I may use it for FPV eventually.

[skydve76]

Just went ahead and bought it, too good of deal to pass up. Will answer my own questions and post here.

What plane are you talking about? You say a Hangar 9 40... 40 sized what?!?! :D

As far as the Power 46 goes, I am using one for now on a Hangar 9 Sundowner 50 on 4S 4000mAh battery pack and getting great performance, though very speedy, with a 13×10 APC prop. I am going to pull the motor and put a geared Neu motor to see if I can get more speed, and put the 46 in the, yet to be released, Hangar 9 Vans RV-8. Probably start with a 14×7 or 14×8 prop and see. I also think that HS-82's may be a little on the small side, I would opt for the 85's at least, maybe the 225's, to get a little more strength. I am using the digital versions of the 225's on a larger plane with very good results.

its the cub.
i went with standard servos as they were cheaper than the 82s
14X8.5e prop
the elevator pushrod is stupid

[realtimerecon]

The hanger 9 (40) size w/ 80" wing, J-3 is a GREAT plane.
I've owned one for 4 years now.I put a EFlite 60 in it.AUW of mine is 8 pounds EVEN.Thats w/ (2) Tanic 4,400s.The servo i used are JR-here http://www.horizonhobby.com/Products/Default.aspx?ProdID=JSP20050
Good luck w/ the cub.You'll LOVE it, & quality is top notch...RTR
PS: one thing you'll need is a big area(final approach) to land , this plane DOES NOT want to land.AS The wing supplies TONS of lift.

[skydve76]

why the bigger motor?

[realtimerecon]

I haul camera stuff.The 60 allows me a 2 pound payload.

[skydve76]

hows the roll rate?
do you use any expo?

[realtimerecon]

I dont use expo.Roll rate is good for 8 -10 pounds.
You did great on the price:D...

[realtimerecon]

Here she is .Talking w/ her younger sister, the S.C. LOL...RTR

[Smash McCrash]

Ah, the Cub! A flying buddy has one and even after the repairs, still flies great!

It looks like I was spot on with the servo recommendations, then. The JR Sport servos are pretty good servos. I have used the MN48's on a couple of planes and they work just fine. Another servo to look at for future projects is the DS821 from Spektrum or JR. High torque and digital for about $20 if you know where to look.

i think i messed up the pushrod for elevator
should the two rods be the same length out of the dowel

They should ideally be the same length. You an adjust slightly using the thread on clevis on either side provided the rods aren't too different. I had to slightly bend mine to eliminate the binding in the rear of the plane. :)

flew 2 times today in 15mph plus winds
two 4s 2200 20c against the firewall
too much wind, power seemed low
14X8.5 apcE prop
perfect for my wife though
rolls loops KE etc
ill probably kill it pushing it too hard
will get some vid, my wifes first aileron trainer!

[skydve76]

What is a spin, and how do you do one with a cub?

[vp46]

one wing stalled the other not or partially stalled....... how you do one in a cub is a good question! My old kit built H9 glow conversion (turnigy 50-65 350kv 80amp esc 6s 4000 mah - auw 8+lbs) will drop a wing if flown as slowly as possible WITH the wind :D

i doinked up my cowel today
on take the tail loves to whip around and I like to punch the throttle

Did you think you spun it in? I am confused by your posts....

[skydve76]

sorry that was on take off

[skydve76]

Again on takeoff, despite several non eventfull ones, suddenly it tip stalls and it hit the corn. Ripped the monokote on the right wing tip on the top. Left some big holes. How do I fix it?

I then tookoff the other direction and it tip stalled hard again, thought it was gone as hard right wasn't pulling out of the left turn, but finally it stabilized.

Then did one more takeoff, perfect. What the heck is going on?

[vp46]

Tip stalls are spins..and generaly avoided by adding Washout to the tips (LE of tip lower the TE of tip). If it is not a construction issue (is your wing twisted aND IF YES IS IT TWISTED equally at both tips?)...

Other possible conclusions:

I think it is possible either your Aileron or Rudder Servo connection came loose. Or possibly the battery shifted?

[skydve76]

the tail really want s to spin around
i think it would start yawing hard when i pull up and it causes a tip stall?

[BrentP]

I just wanted to point out that when I first started to fly this kit (yr ago) I was having what I'll call wing wobble (wings tipping back and forth/tip stall). And I would try to correct with aileron (actually made the tipping worse).

At this time I was learning rudder and that was the problem.
When I got the hang of using rudder and not slamming the throttle on on takeoff things got way better.

Now I ease into the throttle with a little rudder left or right to get it straight at the beginning of the roll and as the speed picks up it is necessary to hold right rudder all through the takeoff roll and through climb out to say 50 ft altitude.

Now ever takeoff is near perfect (and scale) and I have never had the tipping happen since.

When I was having the tipping problem and using aileron to correct I discussed this with a club member, who pointed out that it was rudder I needed to correct with, explaining how say if the left wing dropped right rudder moves the left wing forward gaining lift and getting out of the tip stall.

This seems like common sense now.

This is all elementry to a seasoned or instructed pilots but I learned quick and those embarassing takeoffs are anything but embarassing now.

You may know all this already but I though mentioning it sure wouldn't hurt.

Cheers

[skydve76]

You are correct, rudder is the answer. Crazy to think the "cub" is a "beginner plane" and yet the take offs are the some of the hardest I've done.

I also found another problem. ON landing, under no power, I noticed the plane would still yaw right. Granted I came in way to hot, normally there is very litle rollout. I held full left rudder and it still yawed right.

My tail wheel can move back and forth about an inch, do you think that could be it?

[BrentP]

My tail wheel can move back and forth about an inch, do you think that could be it?

Do you mean back and forth an inch is your control throw distance?

or do you mean the tail wheel has a inch of slop to it?

I think you mean the throw. My rudder (tail wheel throw) is right at the suggested throw in the manual.

[skydve76]

It has an inch of slop :) Because the little collet came loose.

The rudder has no slop, the wheel does, can move back and forth on the axle.

[BrentP]

skydve76

There should be zero slop in the tail wheel wire. As for the collet I like mine so the wheel has no slop side to side, just enough for the wheel to turn free.

The tail wheel wire having slop may contribute to the yawing with power off after touch down, but I doubt a side to side tail wheel movement would.

[skydve76]

heheh landed in the corn today. No damage. Going for a nice tight loop and prop shot off! Not enough speed left to get back to the runway.

My wife is having a blast learning to fly with this.

BTW, takeoff issue is resolved, just hold some right rudder and it works great!

[BrentP]

Hey the cub's not a crop duster :eek: stay outta that corn ;) .

[skydve76]

on take off, someone told me today to use full up elevator up intil the point it almost lifts off. This keeps the tail on the ground and keeps it from yawing on the ground. Is that true?

[BrentP]

Not true for me anyway.
A couple of my smaller tail draggers do require holding up till it's in the air, but that is simply because it will nose over due to the grass otherwise.

I myself wouldn't try that because I did try holding up on the Maiden takeoff roll for my DR1 and it became airborne prematurely and stalled and half cart wheeled (BTW the DR1 is bigger than the previously mentioned tail draggers so it did not need up elev in the end, nor does the cub).

How much wind / crosswind are you flying in?
Have you flown the model in calm conditions? (it is super smooth in zero wind)

I think you mentioned the cub being a trainer but it kinda isn't, with no dihedral lots of drag and boxiness. It is a bit of a handful in crosswinds with the flat sides (including takeoff).

I also had problems in the beginning with the yawing (weather vaning) on takeoff roll, but again a smooth hand on the rudder and smooth transition to full throttle is the key.

How much exponential do you have on the rudder?
I'm using positive expo (soft at the stick centre)
But some prefer negative expo (softer further into the stick movement). If you tend to be over controlling the rudder stick neg expo may help.

And I'll guess that maybe over controlling (over componsating) the rudder is the cause of the yawing, it was for me till I mellowed out my rudder thumb (small inputs).

I'm no pro just letting you know my experiences, hope it helps.

Cheers

Check the front axles for equal movement(lube, if one tire is tighter than the other) .And or, give motor mount more Right angle.And EASY on the power on the first 1/2 .Slowly increase power.And give plenty of Rt. rudder. Remember its a J-3, not a F-22 :D LOL...RTR

[skydve76]

I have 30% expo and 65% range on al channels. It just really wants to start yawing around on take off. Then other times it goes straight up.

Wind or no wind. Seems to do better with a head wind.

THATS NORMAL"YAW ON TAKE OFF" FOR THAT SIZE J-3.
IT HAS TO BE DEAD CENTER INTO A HEAD WIND,AND ALL WILL BE OK.
IF NOT IT WILL YAW,& MOST TIMES TO THE LEFT.(MOTOR TORQUE)
IF,I APPLIED FULL POWER FROM A DEAD START W/ MINE W/ THE E-FLITE 60 IT WOULD NOT YAW LEFT,IT WOULD MAKE A SHARP 90 DEGREE LEFT TURN.:(...rtr

[skydve76]

For the most part, it has been a good trainer for my wife since we have a buddy box. It has some bad habits though. For example, it really likes to drop the nose and pick up lots of speed in a turn. I noticed for her too she stalls it alot, in stead of bank then elevator, its been elevator then bank, having issues with that combination.
Not a good plane for take off or landing. While landing is easy, the plane won't take too much to completely destroy. When we get ready to do landings, may have to get something else.

But the idea is if she can fly the cub, she can start flying other things. We did have a super cub, rudder only, but that won't teach her much and she already mastered flight.

Any input on a good aileron trainger for landings and take offs much apprecitated (electric). I am thinking of something foam and cheap that belly lands to start with. Like the f-27C stryker from parkzone.

THIS IS THE BEST TRAINER IN THE WORLD:).BUY ALL THE FOAM PARTS FOR ABOUT $70.00.ADD YOUR OWN ELECTRONICS.AND CUT AILERONS !!!!!!!!!!...RTR

Im pretty sure they still do. The origional Hero was standard lens, the new one is fisheye.

[skydve76]

Tried a new take off method. I set low rates ont eh elvator of 60%. I j ust hold full up elevator on take off, a little right rudder, and it climbs out nicely. Once I get a up a few feet I let go of the elevator and give it more throttle. Perfect takes offs!

Bad habit to get into though?

[skydve76]

WOw! Finally put my setup on a WOT meter. Using a power 46 and an e-flite 60 A esc PRO. At WOT its pulling 60A!!!

Using a master airscrew k-series prop 14X8. Seems a little much huh?
