I have a new Royal 46  will this have the power I need for a Super Chief? Or should I look for something larger?
Thanks

I suspect that an out of the box Royal 46 should pull its wings off.  If you've got one that's been "stunt modified" it should still have more than adequate power.

They were  ALL  RC  version.  so  most all of them  are  Modified for  stunt. i myself  did  many hundreds of these  plus  the  MAGNUM FSR clones  that were  made at the  same  time  by  Thunder Tiger  in taiwan

Sorry -- I didn't mean turning a venturi, I meant carving up the liner.

How do they compare to the 46LA?

Just gave it another airing . 15 / 9-9- /77 fuel .
First flight was a L e a n BURN , left the kneedle .  bogged and stopped , fairly toasty . 
1/2 turn out , as youd exopect , Pretty much right . Pretty solid 4 into pulling even past half hight .
Next flight , 2 clicks in . 5.0 laps .
Smooth and competant . told it was ' differant ' & ' not a Fire Cracker , by the head honcho at the handle , then there .
Very smooth from outta the ciocle .

12 x 6 thinned . Brodak 6 Oz. adequate . First back swing it lights up . Will go back to the 10 % Nitro to drop it past 5.0 laps .
Seemed just as sound on that last week . thought Id see if it broadened the needle . 3 1/2 open for the 15 , 3 for the 10 .4 m.m.
 OS 40 N V A .

Hauling 76 Oz of Holy Cow , Batman . By Jeeves .This is the Royal ABC clone on the 351 intake . Bog Stock , even std. head shim .
Olde Aeromuddler Mag , 82 W/Champs . seems the Chinese used them , best was 2nd. / Silver medal .the OS FS 45 the R's cloned from .
So it seems they might have potential.

Sat steady throughout the run today . a first for the 1/2 doz. engines ive tried in it. But uncowled . mild weather , hardly a breath of wind .

Think not cross drilling the case , side mount , NVA in venturie  at outside tank edge would have a killer run.

A pitcher , just to see it is the same donkey . will throw a installed picture on before long .

JUst  FYI

Thunder Tiger  made  all these  in  Taiwan
Magnum  40 and  45  and  46  2 piece case  FSR clone
Royal  40 and  45  2 piece case  FSR clone
Royal 46 SF  Clone 1 piece case
46 and  45 2 piece case  Heli motor  FSR clane
Heli 46 Royal  1 piece case

all of these  could be  and still  are  great stunt  engines.,  I am doing  4 of them right now

One showing the case drilled for the 4 m.m. spray bar . Runs well enough to justify fitting one of Mr Smiths P.A. needle valve assemblies .

p.s. in my first endevours at cinematographic excellelance , I got it on film. Some of it . the Tricky parts anyway , so you can wait to be enthralled
untill I post it . In a Few WEEKS . Or My Bro. does , when I next get over there . on you toob . Sq. 8 thru Hourglasss , but 3 clicks lean ,
so not dropping deep into the four stroke on film .
