BiplaneCrasher -> H9 SuperCub/Roto35 Build (2/27/2004 1:54 AM)

This is the begining of the build on my model of the Hanger 9 Super Cub. I have read all the threads here on RCU and found this plane to be an excellent model to break into 1/4 scale. So far this is what I have and followd by what I need to know from you guys.

1) Hanger 9 Super Cub
2) RCS ROTO 35
3) Futaba 9C Tx & Rx

The future holds many ideas and problems. The first is that the ROTO 35 is a rear carbed engine. So far I have outlined where I need to remove material from the firewall. It was not that much but enough to were I feel more comfortable adding a buffer to the rear of the firewall. I plan on mounting the electronic ignition to the inside of the firewall.

This is the first model I know of that is using the ROTO 35. If you are using it in an other plane, please add to this post, or email me. I am interested. Photos will be coming in the future. The 35 may be a little large but, I plan on adding a video and telemitry system to aid in my study of aeronautics.

I wish to get my lisence to fly this year. I tell my wife that if she gives me a hard time I'll take the savings, move to Austrailia and become a bush pilot. She does not like that very much! every man needs an out.

I'll be adding to this post as I go along. I welcome you to add comments, positive and negetive. Both aid in costruction and decisions.

The only question I have now is how do you remove wrincles from the covering? The covering is wrinkled above the firewall back to the cockpit.

Thanks!

Ed

Hi Ed,

Mine is rinkled also out of the box...

Heard on a forum that you can use heat but not on the numbers...

using a G 26 on mine, first gas for me...

Walt...



GalenB -> RE: H9 SuperCub/Roto35 Build (3/13/2004 6:22 PM)

Mine didn't come out of the box too wrinkled... The WorldTex seems to take heat well, and I found that using the iron worked better as the pressure helped set the adhesive better. I would also recommend using a sock -- two socks actually. The red trim will transfer some color to the sock so I used another on the white. I have also clear coated mine using polyurethane.

Here are the specs for mine:

  • H9 Super Cub
  • Brison 2.4 swinging a 20X8 prop
  • Futaba 9Z WCII with a 148DP receiver
  • 6 Hitec 5475HB servos, with a Futaba 148 on the throttle.
  • Robart 1/4 scale Cub gear
  • Cirrus Ventures 1/4 scale Scott tailwheel
  • Gian scale nylon hinges using a full length piece of music wire -- sealed gaps and removable surfaces if the need ever arises...
  • Eventually I'll add floats...


I will post some pictures as I make more progress.



BiplaneCrasher -> RE: H9 SuperCub/Roto35 Build (3/13/2004 10:31 PM)

I have never tried to upload a file here on RCU. But here I go. I dont keep up with RCU. I have been a heli guy for about a year and I enjoy my RunRyder site more. You will see my progress over there but keep checking. It looks like I may have some compitition.

Hey galenB,

I have read many post about engine size and all that jazz. I dont agree with most of it. The brison 2.4 was one of my coices also, but someone already had a plane with that engine and I can't be the same as anyone. The 35 may even be overkill, but with all of the extra wiegt it may not. After all it is a utility plane isn't it?

Lets have fun and check me out on RR, I am "Freqency47", and my posts are listed under "Super Cub Build".

GalenB -> RE: H9 SuperCub/Roto35 Build (3/14/2004 4:33 AM)

My Brison 2.4 choice came down to:


  • Weight -- the Brison 2.4 is lighter than a Zenoah G-26
  • Cost -- the Brison is cheaper than a G-26 with ignition.
  • Usefulness -- the 2.4 can be used in more planes than a G-26.
  • I already have a Brison 3.2 and have found it to be a great engine.


My 2.4 arrived last Thursday and the new polished crankcase is great! The test run report is 7700+ RPM with a Zinger 20X8!



papadale -> RE: H9 SuperCub/Roto35 Build (3/14/2004 5:11 AM)

Don't let the rear carb concern you to much or removing some of the firewall. these are pictures of a zdz 60 rear carb I mounted on a wild hare edge. It is very strong and I needed nothing else. Also the rear carbs draw better.

Good luck on your build
Dale



BiplaneCrasher -> I agree (3/15/2004 3:10 AM)

I have used the Hitec 5475 servos in my Hanger 9 Ultra Stick andI love them. Maybe not the quikest for that application, but the control surface area on the stick makes up for the .02 tenths of a second lost for an increase of $50.00 for a other servo.

I will also be using them in this plane, but only for control surfaces, and not throttle or anything like that. I'll most likely use the standard Futaba S148's in that application.



BiplaneCrasher -> Update June 1st (6/2/2004 3:55 AM)

Finaly getting some free time now that I am on vacation. I have spent a few hours applying some ideas that took me a couple of week to think of. And like the rest of you I would stare at the aircraft like some mechanics stare at an outomobile engine. After trying a few arrangments of the servos this one worked the best. The servos are going to stay in that position since they leave room to remove the fuel tank, and access to the fuel lines in the event of a problem. The servo to the left is for the throttle and the right side is for the choke. The controll rods are made from hobby store stock died to 2-56 and then JB welded on the engine end, leaving the other end variable. Most of the parts you see used are from left over repair parts from heli crashes.

The Roto35 is a great engine from what I have read. The install was not difficult but the servo installation was a bit of a pain. This plane was designed for a large nitro engine. Hanger 9 had left no slot for a fourth servo to controll the choke. That would explain the extra servo tray against the dashboard. I don't mind doing the extra work, that is what I enjoy the most. After fitting the switches and batteries I'll finish the cabin to a semi-scale look.

At the bottom of the photo you will see aluminum plates. I manufactured these out of 1/8th inch flat stock to mount the Robart landing gear. After loosing the bottom of my Ultra Stick due to the landing block being under built, I thought it was a great idea. Behind the firewall you will see a blue and silver box. This is the ignition box for the Roto35. That is a great location since it needs no adjusting, it need not be in the open like a gyro on a heli might be.

The last mod is the fuel tank. That is a Sullivan 32oz. fuel tank. Maybe a little large but I get lazy at the field and hate fueling and charging, so this tank should last me at least two flights. For appeal I added some balsa just to make the firewall a bit less ARF looking.



mAvRiCk-inactive -> RE: Update June 1st (6/3/2004 2:41 AM)

Hey guys, Dan here...well I received my H9 Super Cub from chief with the G26 because i'm a kid and can't afford anything and it was a combo and saved some $$$...first warbird like scale plane here ever! My setup:

Radio: Hitec Eclipse or possible the 10X

Servos: Hitec 645s or 5945s either ones I have on hand

Batteries: 1 4000maH Duralite Plus battery

Receiver: JR R955 or Best Hitec receiver depending on choice of radio

Looking for a place to get a smoek muffler for my G26? Are there any? Any suggestions? Any help appreciated

Thank you,

Dan



Steve -> RE: H9 SuperCub/Roto35 Build (8/18/2004 1:07 AM)

Has it flown yet?



BiplaneCrasher -> RE: H9 SuperCub/Roto35 Build (9/13/2004 11:07 PM)

Here is the 98% finished Hanger 9 Super Cub. I found a way to stuff the Roto35 into the cowl, I would have put the smaller Roto25 if it was available at the time I purchased the 35. The cowl is slightly butchered. that's a bad way to describe it, it was cut decently with a Dremel but my measurments were of and I removed 1/2inch extra around the exaust. To clear the prop drive hub, I needed to enlarge the opening by 1/8th inch.

Anyhow, this photo was taken at the Orange County Flyers field in Walden, NY. I had the field all to myself being a work day. I only need to place the antennae, route the vent tube into a better place, and finish installing the windows. The windows are covered in black vinyl because when I installed the first two window the CA misted the surface into an un-repaiable state. I like the finish this way, if the cockpit was detailed I would have ordered new "glass" to show it off.

It took 100 pennies to counter balence the Roto35. I removed some covering just before the tail on the bottom to install the counterwieght, and then resealed it. The overall finished wieght with a full tank of gas must be 15-20lbs I would guess without a scale. I may pick one up from dick's sports to rate thust and wiegh planes. The Roto35 sounds like any other 2 stroke I think, it is kinda deep compared to a Zenoah G-23. Today I reached the field, assembled the plane and then tried to start the engine only to find that the 35 is too strong for the high torque starter motor, evn at 24 volts. I need to invest in geared down starter.

Here is a picture from today at the field.



cadconversions -> RE: H9 SuperCub/Roto35 Build (1/25/2005 6:03 AM)

How did it fly?



CrashBurn69 -> RE: H9 SuperCub/Roto35 Build (1/29/2005 3:54 PM)

Any updates or video? I have on with a Ryobi 31, thats just waiting for good weather to fly it.



mar345 -> RE: H9 SuperCub/Roto35 Build (2/2/2005 2:09 AM)

Hi Guys,

Mine is being powered by an OS 120 mounted inverted as per instructions. Swings a MA 16-8 prop at 8500 rpm or a MA 18-6 at 7400. Trying to keep it light. Should fly very scale like...I hope.



BiplaneCrasher -> RE: H9 SuperCub/Roto35 Build (3/28/2005 7:24 AM)

The Roto35 was too much power for the Super Cub. I am switching over to a Saito 150 and I will leave it that way I should have enough power for anything I desire in the future without overpowering it. Here are some pics. Last year I ditched on the maiden flight and spanked the elevater. So I recovered it with colors that are easy to see, I will have an L-5 or Wilga soon I hope and will make one of those more scale. This is a fun fly plane now, probably will make it into a tow plane and/or candy bomber. It was entirly recovered in Monocote wit silver auto trim tape.

Here are some after and before shots.



rionp -> RE: H9 SuperCub/Roto35 Build (7/13/2005 6:57 PM)

Hello:
I'm looking for a Cirrus Ventures 1/4 scale Tail wheel. Do you know where I can find it ? thanks a lot in advance.



GalenB -> RE: H9 SuperCub/Roto35 Build (7/13/2005 10:09 PM)

Cirrus Ventures advertises in R/C Report. Get an issue and look for their ad...

rionp -> RE: H9 SuperCub/Roto35 Build (7/14/2005 3:31 AM)

Great, thanks so much.
I'm building a Dave Patrick Super Cub and I want to add some scale items, like that tail wheel. Thanks again.



Juan Rodriguez -> RE: H9 SuperCub/Roto35 Build (8/1/2006 6:51 PM)

Guys,

I'm looking for a manual for the Hangar 9 Super Cub ARF version.... anyone have any ideas where I could get one ?? On line , maybe ??

Thanx,

Juan



tailskid -> RE: H9 SuperCub/Roto35 Build (8/2/2006 4:55 AM)

Have you tried Horizon's web page? They have manuals, but I don't know about the Super Cub because it has been out of production for a couple of years.

I do have one NIB that I'm going to get to SOMEDAY....

I have and they don't..... probably due to the reason you stated....

Any chance you can make a copy of the manual and mail it to me ? I would be happy to cover the postage....

Please let me know..

Thanx

Juan



P-51B -> RE: H9 SuperCub/Roto35 Build (8/2/2006 2:57 PM)

PM me your e-mail and I will send the PDF version I downloaded from H-9 a while back.



Juan Rodriguez -> RE: H9 SuperCub/Roto35 Build (8/2/2006 3:18 PM)

That's GREAT !! You're a life saver !! [:D]

Thank you very much...

Juan



P-51B -> RE: H9 SuperCub/Roto35 Build (8/2/2006 5:29 PM)

It should be in your in-box. You may want to remove your e-mail addy from the public boards though.
