Uncle Ivor's Outlaw

I remember building a Keil Kraft Outlaw (original design) in about 1959. I used a DC Sabre 1.49cc (which I still have somewhere) and it flew beautifully on Epsom Downs.

I note that Ben Buckle still produces the printed balsa version of this kit but I can find no-one who does a laser cut kit although virtually every other KK model is available in that form. It would be nice to make another now - probably with rudder and elevator - but without the hastle of cutting out the fiddly ribs.

Doesn't time fly! Nearly thirteen years since I started this thread and nearly ten years since the last post! However, I have decided to restore Uncle Ivor's Outlaw as a single channel model powered by the ED Competition Special in order to teach free flight trimming techniques to younger members of my club. I also intend to cover the model in tissue over doculam which will be a first for me.

 

However, I need the help of the cognoscenti in choosing a servo to actuate the rudder. I have the following small servos in stock:

 

1. A Savox SH-0255mg.
2. A Hitec HS55.
3. A Hitec HS5055MG.
4. A Hitec HS-225BB.

The first three servos are probably designed for use with electric models because they are supplied without any rubber grommets.

 

Would they be suitable for a model powered by a diesel engine?

I still feel the need for advice concerning which servos to install in the Outlaw which is a 50"vintage KeilKraft kit.

 

I will be powering it by an old ED Competition Special. I have a Hitec HS55 and an HS5055MG which I could use. Going slightly larger I have a pair of Savox SH-0255MG and going larger stilll I have a pair of Hitec HS225BB servos. I could always buy another HS55 or HS5055MG to produce a matching pair if necessary.

 

Which would you recommend?

I revived some enthusiasm for Uncle Ivor's Outlaw by building the tail plane yesterday. I used De Luxe Materials Super Phatic glue for the build. I'm most impressed by this glue. I have decided to go with two elevators and I plan to increase the size of the wood in the fin and rudder from 1/8" to 3/16". I hope that does not make the tail-plane too heavy but I will have the rx battery and servos well forward to compensate.

Do you think that a Hitec HS 55 will be strong enough for the job of actuating the rudder and elevator? If not I'll buy another HS 5505MG. Photos of the build will become available once someone shows me how to use my mobile phone as a camera. My real camera is hors service.

I have finished the tail surfaces and I'm just waiting for some small hinges to turn up before proceeding. No pictures I'm afraid as my camera is u/s. I have taken a few pictures on my phone but don't know how to transfer them from the phone to the internet. I have asked an IT expert to assist me.

The fuselage of Uncle Ivor's seventy-six year old Keil Kraft Outlaw has been prepared for covering in doculam and though you can't see it the servo plate has been installed. I need to open up the hole in the former to allow for the egress of the elevator push rod and the rudder's closed loop cables.

 

The sheeted area of the fuselage was covered in at least three coats of paint so it took two or three goes with paint stripper and my orbital sander to get to this stage.

 

The next job will be to install the servos, switch and elevator push rod before continuing with the covering.

I have hit a couple of snags.

The fuselage is very narrow and the servos are mounted well down in the structure which means that they are not very accessible. This is the first time that I've used Hitec HS 5055 MG servos and their extremely small size has posed some problems. For example I had to move the output arm of the elevator servo but even my smallest Phillips head screwdriver was too large for the set screw which retained the output arm. I found one in my kitchen drawer which had been included in some long defunct ARTF kit. That fitted!

I have a little 400 mAh four-cell NIMH battery which fits nicely between the engine bearers but it has a little BEC connector. This a small red component about 1 cm long by 5mm wide. I cannot get it to connect to the switch harness. I am going to replace the BEC connector with a more conventional fitting.

One step forward etc..

JST? Pretty much standard on smaller LiPos..... and lots of low amp esc are fitted with them. Or were, last time I looked for one.

Thanks for the info GG. I'm not really much of an electric flight man. I have a pack of more conventional connectors but I'm no good at crimping them onto bare wires. I will solder the wires onto an existing cable and terminal.

 

Perhaps JST connectors are BEC connectors in French! 😉
