About this Plan
Keil Kraft Phantom. Classic control line trainer model. Plan includes a sheet with hand-drawn tracing of the kit parts.
The original (open cockpit) Keil Kraft Phantom (oz1397) first appeared in the 1940s. This here is the later version of the plan, with bubble canopy.
Quote: "Keil Kraft Phantom. Building and Flying Instructions:
Any beam-mounted .09 cu in glow motor (or 1.0 - 1.5cc diesel) will power the PHANTOM satisfactorily and the bearers will accommodate most motors of this size without modification. The bearers are of generous size and, if necessary, can be trimmed down to fit motors with an extra-wide crankcase or crankcase backplete.
Build your model with care, checking that all joints are strong and accurate and you will be rewarded with a model that will give you very many hours of flying fun. Follow the building sequence given and you will find no difficulty in making a first class plane.
1. Cut the engine bearers to length and cement firmly to the fuselage sides. Take care to make one right (starboard) side and one left (port) side. The cut-outs to allow the lead-outs to pass through will only be required in the left side. Drill F1 as shown on the plan and bind and cement the undercarriage to it, using strong thread. (STAGE ONE).
2. Cement F1, F2 and the Cockpit Floor to the right fuselage side. (STAGE TWO).
3. Add the second fuselage side and F1A. Leave to set. (STAGE THREE). If you are fitting a separate tank, install a KEILKRAFT 15cc Team Race tank between the bearers in the position shown. It will be necessary to make a hole in F1A to allow tank feed to pass through. Cement the tank securely in place.
4. Install F3, putting en elastic bend on the rear end of the fuselage to keep the sides pulled in and when the cement has set, cement the two top blocks in place, followed by the two pieces of 1/4 x 3/16 (6 x 5mm). (If a separate tank is fitted, cement the front block In place lightly, so that it can be easily removed later on). Drill the engine bearers to take the engine mounting bolts and Install them, locking the heads as shown in the sketch on the Wise. Then carve the bottom block roughly to the shape shown in the fuselage side view and cement in place. (STAGE FOUR).
5. Carve and sandpaper the top Wrecks to give a smoothly rounded top to the fuselage, and shape the bottom block to fair In with the spinner. (STAGE FIVE). Note: If you are using ein engine with an integret coil spring starter you will not be able to fit a spinner so just round off the front and take care that the spring does not foul the fuselage.
6. if a separate tank is fitted, remove the top front block and lbw drill to take neoprene extensions to the tank filler pipes; fit the extension and then cement the block permanently in pos-ition. Make a hole in the bottom block to allow excess fuel to drain away, and then give the engine bay two or three coats of coloured dope, followed by a coat of fuel proofer.
7 Sandpaper the back of the spinner, so that when it is fixed to the engine, the back of the propeller and the back of the spinner are in line. Bolt the engine in place and make the cowling as shown on the plan, first fitting the two cowling sides, and then filling in between them with the 7/8 x 1/2 (22.5 x 12.5mm) balsa provided. Remember to allow spaces for choking and filling as necessary..."

Added supplement alternate scan (greyscale) of the same plan, thanks to aeromeddeler. This file also includes scan of formed UC wire, also the plywood parts for bellcrank mount, F1, line guide and dihedral braces.
Update 10/09/2019: Added kit instructions, thanks to ChrisBayliss.

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHello Steve! I just wanted to show you some pics of some planes I built from Plans available at Outerzone. These are the Keil Kraft Phantom, finished in 2015 [more pics 003, 004].

Added three great photos of the Phantom [more pics 007-009] thanks to AntonioRG.

Hi Mary, Here are a couple of photos of the KK Phantom I built in the '80s with a PAW diesel [more pics 005, 006]. If you fit a big engine, they fly a bit faster. If you fit a small engine, they fly a bit slower. Whatever engine you fit, they just go round and round. But they will show you the fun of control line flying and you just HAVE to build one sometime.

I have to confess I have never actually built a model of any type, just watched admiringly from the sidelines as Steve builds his. One of my resolutions for 2017 is to scratch-build at least one plane. Maybe I'll make it the Phantom :)

Added lovely picture of completed model, thanks to Alf Britchford [more pics 010].

My son and I are currently building a 120% Phantom Mk2 with an HB25 for power. The original Keil Kraft design had the bellcrank attached to the top of the wing, which makes final assembly a fiddle. So I flipped the bellcrank upside down and attached it via two 8x8mm hardwood supports to the underside of the cockpit floor. The controls can be set up without the wing being installed and the bellcrank connects structurally to the engine bearers above the floor- stronger! I have left the bolt long so it will push into the wing thus supporting the bellcrank bolt at both ends. Stronger still! I thought that future Phantom builders could consider this alternative [see more pics 011]. It doesn't alter the appearance of the model, which is good.

Hi Steve, Thought you might like to see the Phantom I’ve just completed [pics 012, 013] from the plan I downloaded from OuterZone. For decades I’ve been intending to revisit my boyhood hobby from the 1960s, and the pandemic has given me just the kick up the rear I needed!
The build has been a bit of a labour of love, I almost didn’t want to finish it and I spent far more time on the finish than I ever did when I was young. I did pretty much everything the old-fashioned way - stitched elevator hinge, fuel tank made from an old biscuit tin etc, although I decided to make the tank ‘uniflow’. Unfortunately, I didn’t do enough forward planning and the fuel feed from the tank is positioned such that I had to incorporate a non-standard ‘power bulge’ on the starboard side to accommodate the fuel supply tube. The engine is an AM-10 (one of the engines I owned back in the day) that I found on ebay some months back.
Only trouble is, I’m so pleased with the result I don’t want to fly it in case I break it! I think I’m going to build a quick and dirty profile fuselage model to get back into the swing of control line flying first.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
