magnum 52 xl blue head

[B Norton]

I've been looking @the magnum 52 and wondering if anyone had any experience at converting one to control line?

[Motorman]

My experience is with the 36 size back in the 90's. If you get one with a good piston/sleeve fit it will be a fine engine. As an engine builder, first thing I would do would be to take it apart, de-burr and clean everything then re-assemble with boca bearings with single rubber seal front.

Stuka Stunt did conversions on this engine. Lowered the deck height and plugged the boost port. Good engine.

I knew he did the Magnum .53, I did not know he had reworked the .52, its a different case as far as I know, he may have, but I am not sure

[Andrew Tinsley]

If this engine is the same as the ASP 52, then it is a good unfussy stunt engine. I simply check for foreign bodies and put in a .275" to .285" venture which I turn up myself (this is using the OS NVA).
I have yet to change the bearings in either of my engines. They run just fine with no other mods. They can do a wet two right the way to a mild 4-2-4, depending how you set them up. No real vices and they have a lot more power than say an LA46.

[Randy Cuberly]

I believe Randy Smith sells reworked one.  I have a Magnum 40 from him and it runs great!  Powerful and tame!

I do the new  Bluehead 52, there  are dozens of mine out there, it is a differant motor than the old 52  53 
They are very powerful engines

Randy

[Motorman]

Randy, what do you do to them?


MM

[RandySmith]

Randy, what do you do to them?


MM

Balance  blueprint, convert to C/L venturie and PA  needle assembly, and head mod

they are  only availble as an RC motor

Randy

[Shug Emery]

I have on waiting to go on my TF Score. I have bench run it and it sounds right good.
Bought mine from Randy so I know it'll do what he says.

[B Norton]

Thanks for every bodies input.I was thinking of doing same project as shugs I have a old score that the covering has come off and needed new power. So keep me updated on your progress.

so you want his recipe?
thats like asking a surgeon how to perform an appendicitus operation so you can do it yourself

[WR Crane aka MrClean]

Or you could do what some people do, buy the engine, look for the mods (have to know what you're doing here) then do a bunch more of them and claim they're your mods.  Not saying anyone here has done that, but know of a few instances.  Ahhhh, sometimes there is real snake in the snake oil.  I knew this one dude whos Fox 35's snarled more like a K&B on 85% nitro.  Wonder how that happened?

More like a brain surgeon asking how to do a heart transplant.

Hi Guy's,
I've just received my Magnum 52 XL from Randy, and what a jewel.  I've purchased many motors from Randy over the years and they are worth every penny.  They run as claimed and expected.  I plan on installing the Magnum 52 XL in the New P-Force XL, it should be a killer combo.

Later,
Mikey

What size plane and what prop and muffler or is that top secret too.


MM

MM

THAT was a bit of passive aggressive there
its not top secret, but it is knowledge earned by experimenting, trying , failing and trying again. He makes money to do this. Somehow I get the feeling you would expect a nascar crew cheif to give up his knowledge just because?
LOL
perhaps you should buy one then attempt to reverse engineer it? then at least Randy would get something for his efforts.

MM

2 BLADES 13 X 4 , 13 X 4.5  13.25 X 4.5   2 BLADES  AN OLD  BOLLY OR CLONE  13 X 4.25  WORKS GREAT, OR BUY THE  Zinger pro prop kits and thin/trim one, or REV Up  Top Flite  13 x 4 or 13 x 5

3 blades  - 12 x 4.25, 12.5 x 4.5  13x 4.75   CF are best

any muffler that fits a OS 46 SF, or  TT 46 or Mag 46  will work, also I have tongue mufflers, the stock muffler works but is heavy

Sort of speaks for itself without me have to write for hours, if you know how to "balance a motor"
then you would not have a  problem, others destroy many parts
if you know  how to blueprint an engine  then no problem, some  kill things

same for head mods that actually work, converting over to  C/L
making the proper size induction part  and Needle assembly

reitiming  or re-angling ports  when needed,  this is where  tons of new parts are destroyed

then figure out how to get it to run best for what you have to  install it in

 Just got magnum 52 blue head in the mail hopefully have a couple tanks of fuel run though it by monday evening.Got to get a venturi made monday morning. Cant hardly wait !!!!.

[B Norton]

Went out to Bob Reeves shop this morning to use his lathe to make a venturi.Used some dalron made it with a .281 opening used a super tiger 51 needle valve .Put to tanks of fuel through it ran perfect!!from a wet 4 stroke to a fast two stroke in a half turn of the needle cant ask for much more than that I'm very happy!

Some give help some are up tight about it. See my thread in the speed section. http://stunthanger.com/smf/speed-talk/fox-on-the-run/

Just wanted to share my experience .Maybe it could help someone. That's what I like about the control line most people want to help and enjoy sharing there experiences .

Good to hear. I have mine mounted in my Score. Looking forward to seeing what it'll do when I finish the Score.

[John Leidle]

   Shug , do you mind telling me what glo plug you have in the Magnum ?
            John

[B Norton]

Ive got mine mounted but am building balsa cowl ,got refinish the fuselouge  ill let know how it goes.

[Shug Emery]

            John

I do not know...it came with it.
Sorry.

[mike londke]

Motorman, your typing comes off pretty harsh, not just in this thread but many of your posts. I would like to think if we were all standing around talking control line engines you wouldn't seem like such a tool.  

[Dan McEntee]

   As I read that thread, it's largely about stuff that didn't work. How does that help anybody? And you never enlightened us on what the final outcome was. Randy has multiple, multiple National and World Champions use his stuff, not to mention a legion of Joe Bellcranks out there using his products. Not that Randy can't speak for himself, but just in case you didn't know, I thought I would point that out. And if you read the forum thoroughly, you will find that he is more than quite helpful to everyone that asks about the everyday stuff in stunt. As far as reputations go, you have a long, long way to go to catch up with him.
  Now, tell me how I always have to win my arguments again.
  Type at you later,
   Dan McEntee

[john e. holliday]

Best way to win an argument is when you know you are right, is just let it go and ignore them.  Now if I could live up to that.  

[Greg McCoy]

Henry Ford is reputed to have paid a large bill itemized "knowing where to tinker".

[Rich Perry]

How will this engine do stock, with no mods?   Of course a needle and venturi would be added.  I was thinking of putting one of these in my old Sig Magnum.

[B Norton]

I ordered mine from power hobbies and made my own venture and use a stock st 51 needle valve it seems run great we will see! As soon as I get that score done!

[Andrew Tinsley]

I have done the same with my ASP version, just a delrin venturi and an Enya pro NVA. In this form it is a very strong performer. I don't doubt that Randy's modifications will make it a much better  performer. However just putting in an appropriate NVA and venturi makes it a very creditable control line engine.
I must admit that I don't like Chinese engines much, but credit where credit is due. I have a second (new) ASP and this one is very tight, I suspect it will need a fair bit of running in. This one, I suspect, will not give the same result as my second hand conversion. Work on the ring may well be needed. I am a little reluctant to even run it with such a tight ring set up.

Andrew.

[B Norton]

The reason I went with this motor was because I needed good reliable engines at a cheap price, and since they quit making the LA 46 I needed something. I  could auger in three or four of these engines for the price of one nice stunt engines.With me just starting the pattern again it just make more sense .I own a really nice ro jett 61 but I'm not there yet.Just explaining sorry about the ramble.

[B Norton]

Well score is finished maybe get some flights in this week and find out just how good this motor is!

[B Norton]

After a lot of work I got elevator & stabilizer fixed on the score now if the wind dies down a little ill see just how good this mag 52 is .I guess that's what I get for leaving the score with no monocote on it for almost ten years.

[Garf]

I hope you at least put some bench time on the engine.

[Avaiojet]

What does the Mag 52 weigh?

Charles


It weighs about 12.5 ounces  (  added by  Randy Smith)

[Mark Scarborough]

What does the Mag 52 weigh?

Charles

soorry I was going to post the actual weight so you did t have to follow the link to Towerr

Weight with muffler: 17oz (453g) Weight w/o muffler: 13.6oz (374g)

[Steve Helmick]

Subtract the weight of the throttle, which weighs 45.8g, but add a Delrin venturi, which weighs very little, and a good NV Assy., and Bob's Your Uncle!    Steve

not sure I buy the carb weighing an ounce an 3/4,, 48 gr? Steve where did you find that, I know my Magnum .53 is less than 11 ounces and I have had one of these 52s and they are heavier by a fair amount

[Steve Helmick]

I weighed one myself, and it was 45.8 grams, not 48 grams. I didn't do the conversion to ounces. I thought maybe you would have an issue with the "Bob's Your Uncle" part of my post.   Steve  

PS: Weighed on my Ohaus triple beam balance, bought new many decades ago. It's never weighed anything that is or has ever been a controlled substance...except controline planes, which are a controlled substance by definition...and free flight planes, which are sort of controlled for awhile, and then not controlled for awhile, also by definition...

[B Norton]

OK finally got to put a couple flights in on the score and the magnum 52  the score flew well very stable has a couple trim issues very fixable not bad.The magnum plenty of power might need to experiment with props to get that sweet spot but exceptable like it very much.
