Hangar 9 10cc Ultra Stick Rebuild Project

July 2019: Maximillian (Max) Burton our Club Treasurer, crashed his Hanger 9 Ultra Stick Wednesday, July 17th. As you can see not pretty. However; since I was flying at the field to maiden one of my rebuilt mash-ups and witnessed the ‘thump’, and looked at the remaining pieces, I offered to rebuild it for Max as a project and post the process and pictures to the website. Luckily for Max the OS .65 Engine was fine along with the servos. The receiver was toast, yet the satellite receiver was good. Wheel pants pretty wrecked as well as fuel tank. Horizon has replacement wheel pants but may try to repair since I’m trying to do with parts on hand.


I did suggest Max buy a new receiver from Bruce Carr (A&E RC Products) at the Warbird Event so have that now. So here we go. If you haven’t rebuilt a crashed bird I hope this helps if you want to try sometime since a lot of crashes are not automatically ‘Trash Can Candidates’.  Luckily, the crash recovery crew that day picked up almost all the pieces.

1. The starting point is to assess the amount of damage and determine if it is salvageable. So several questions you need to ask at this point:
A. Is this something I want and can do…..time, desire, skills, etc.?
B. Is there enough parts still left undamaged to make it reasonable, cost & time effective?
C. Are there any plans, guides, resources, spare parts, etc., available to use as templates or replacements?

2. If so, take everything back to the shop; if not, strip out everything useful and keep. Generally, not advisable to keep any radio gear.

Fun comment from guy on Balsa Model Aircraft Builders Association FB group in response to my post of this rebuild…..“Nothing you can’t rebuild with a bottle of $2 epoxy and popsicle sticks”!


As you can see from the damage the plane impacted on the right side of the nose almost straight in. Fortunately, the left side was pretty much intact and provided a template for making a new right side for the fuselage. I elected to do the fuselage repair first and save the wing for later.

3. First steps were to strip away some covering and square up the balsa underside, and then re-glue the fuselage where it had separated. I already know there is some additional damage at the tail but will do front- end first.The left side of the fuse where the power/receiver switch was needed some repair, so I removed that and glued and sanded the fuse while waiting on glue to dry.


4. The left side of fuse had a little nose damage which I repaired before using it as the template for the right side replacement. Also, I straightened out the servo tray and re-glued it at that time. After tracing the template onto some file folder stock I cut it out to trace onto the 1/8″ balsa strip.

Digital Scale – Weights for RC Plane

An efficient way to determine how much weight you need to add to your plane to balance it is to put coins on the plane then weigh the coins and covert the weight to an equivalent weight of lead. A handy scale is a 0 – 5 lb digital food scale which can measure in 1/8 oz or 1 gram increments. The photo shows the scale I use which I bought at Target which I use exclusively for balancing the plane.

RC Plane Work & Transport Stand

For a robust way to work on your plane and transport it to / from the flying field, build a stand from 3/4″ PVC pipe, 3/4″ pipe flanges, stainless steel screws, pipe insulation and poplar. It takes about 4 hours to build, but the effort is worth it. With my stand I can work on the plane in normal orientation or upside down. When upside down I can attach and remove the wings.

Balance of a Tail Heavy Plane

If you discover your plane is tail heavy when you balance it for the first time, first ensure your battery or other “heavy” objects already in the plane are as far forward as possible. Once done consider moving the engine further forward by adding spacer washers between the engine mount and the firewall.

Don’t Screw Up

If you need to screw in an Allen head servo screw and it won’t stay in place, you can use a little bit of a plastic bag to hold it in position. Just cut, or tear off a little piece of a plastic and double it up and press it into the screw. It should hold it long enough to get the screw started.

Plane Balance Rig-up

For a quick and easy way to balance your plane, drill small holes in the opposite side of the fuselage at the CG and insert a small eyebolt in each hole. Hang the plane from the ceiling using light weight chain with “S” hooks and you have a handy and secure way to quickly balance the plane without help. Once balanced, remove the eye bolts and cover the holes.
