Tips for magican
« on: January 05, 2012, 05:21:30 PM »
Just purchased a magican from Brodak and was wondering if there is any tips in building the Brodak version. I planned on using and old Super Tigre 35 from back in the the day when my dad flew, it has very low milage on a new piston and sleeve from years ago.  I have been reading the articles from Pampa on (How to build a better profile) and was planing on extending the engine mounts back to the leading edge and recessing the fuel tank, also purchased  a uniflow tank because mufflers were not available for this engine. I am not sure how thick the wood will be  for the stabilizer but I have read here that some people used 3/16 thick wood  on the stabilizer and rudder. Any building tips are appreciated to help me become a better builder. Thanks

L just finished a Pat Johnston Magician, which was the Midwest kit version. The 3/16" stab and elevator is a good idea. Back in the day, we used to have problems busting the stock stab.
Per Pat Johnston, I also moved the stab back two inches. Don't know if you need this on the Brodak version.

Hope this helped.

Thanks Larry , when you say move the stabilizer back 1 to 2 inches does this mean to just move the stabilizer or does it mean to make the profile body longer? Also when doing a search on this site what does increase the movement refer to ?

On mine I moved the stab back and used the kit fuselage. Remember the Pat Johnston Magician is 48" and the Brodak is 40" wing span.

Look under Paint and Finishing, topic Paint Stand. There are pictures of the Magician in various stages of finish and a couple of its first flight.

Do you still balance the plane according to plans when you change this location? Also what kind of engine are you using? I know most people are going to tell me to use a 25 motor instead of the old 35. I am not disputing the run characteristic of the modern 25 ( I have 2 OS25's and they both run great thanks to the advise from fellow modelers on this site) but I would like to use the Super Tigre because it is just sitting around gathering dust. I am thinking on making this build kind of an old school plane and motor but with a few mods to help run and flight performance.
  This was also the very first model that came home in one piece back when I first started to fly 25 years ago, so I am trying to take a trip down memory lane.

I'm running McCoy 35 Red Heads, old school. I balanced it by the plans.

In fact the McCoy that are on the plane in the pictures is my first 35 that was given to me by my parents. Engine is 50 years old, but had to be replaced with another engine, McCoy. The original Red Head is now in a place of honor in my display case. It just didn't have enough power due to being run hard in its early life.

My Magician has a weight box, but no adjustable leadouts. Due to the wing tip configuration, I couldn't come up with a way to make 'em fit.

If you are building the Brodak Original Magician which used to be the Walter Umland kit if I remember right.   Move the .35 back a tad if you use a muffler.   No muffler it will work where shown on the plans.   I still have my Brodak Original Magician that is powered by a Brodak .25.   One of the best profile planes I have.  Now if I can only get it back from my grandson.

My next question is can this plane do the full pattern? The reason I ask this is I can not do the full pattern I have started to learn most of the pattern with a Galaxy profile running a OS 25 LA but it flies really fast and some times gets pretty Squirrel  and almost out of control trying to do , squares and triangles and over head figure 8's.My goal is to get enough experience to show up at our cities local control line club and not look to foolish if I can ask to join or at least fly with them.

HI Scott,

The Magician can do the whole pattern, no problem.  Really search some of the "Trimming" posts and ask questions about your specific problems when flying.

Don't worry about flying the whole pattern before you join your local club. You'll be amazed at how new or retread pilots are helped.

Received my kit today and was wanting to know if I should put in an adjustable weight box and should I try to put in adjustable lead out guides? The plans show the lead out guide as an option but I'm not real sure how to alter the wing tip to make the small channel for the wires to move in. If I do the adjustable lead out guide how much fore and aft movement should be needed at the wing tip, and if you use an adjustable guide is the center of the nylon sliders starting point mid way between the original spacing for the fixed line guides? If a weight box is used do you put it inside the last rib and leave out the last half rib?

Your best bet is to join your local CL club FIRST!  They will be glad to have you around, will save you a ton of grief and will probably have a guy that will give you a ship because he has too many.

The tip weight box may not be necessary because on equal panel profile models you have the engine acting as tip weight.  On unequal panel profile models I have seen people put tip weight on a profile in the inboard tip.  Probably 1/4 ounce is good on an equal panel ship.

Same goes for an adjustable leadout.  I will probably hear about this but go to Brett Bucks bench trimming article and set up the CG and leadouts as he sets he recommends.  You will get a very fine flyer definitely good enough to learn the pattern with.
