Supertigre .45 vs...?
I will have a slightly used Supertigre .45 in my hands soon...I am wondering how it compares to a Pro .46? I've been searching around on here and have not found that much. Most RPM readings are with tiny 10x7 props and other little props.
How will it do with an 11.5x4, 12.25x3.75, or 12x4? I've always had the impression that they have a little more power than the Pro .46 and O.S. .46 FX... How does it compare?
How do they compare when it comes to weight?

Apparently the Supertigre .45 is 18.5 ounces with muffler, while the Thunder Tiger Pro .46 is only 17.01 with muffler...
This is ridiculous. A 9.5x6 is one of the Supertigre's recommended props...A 9.5x6!!
I also just saw that the Thunder Tiger is rated at 1.43 Horsepower at 16,000 RPM...The Supertigre is rated at 1.5 HP at the same RPM.

Propnut where are you. He is a ST45 guru. He can make one, run perfectly. When I saw him running one, I swore it wasn't a ST45. But I was wrong. he works wonders on a ST. I think the ST is a great motor, just a crappy carb design.
But, I like the TT.46 pro better. I had a ST45.. ran it with stock muffler and moosecan. Carb was to finicky to hang on prop. Sometimes, it would load up, and cough in a long hover or lean out in a hover and die. ST45 is a great sport motor, but I won't put another one on a plane that hangs on prop.
As for RPM figures, I think they are real close in power. I think the ST will out turn the 46 200-300 RPMs. But I have a TT46 using stock muffler with baffle removed flying on a knife kit, that turns a 12x4APC at 13,500 flying. I couldn't believe it was turning that much so I tached it with 2 diffferant tachs. It hovers my 4lb 5oz knife at alittle over 1/4 throttle.
My ST45w/ moosecan muffler would turn a 11.5x4APC at 14,000 RPM peak.

The only guy I have heard of using them with good results is Jim aka Propnut1. Besides him, nothing but trouble. I would not hang my planes in a low hover on that engine. Have seen to many ST running like crap at our field. I had a 90 that you could either set to idle and no midrange, or good midrange and sacrifice idle. Also not near the power a 91 FX would have.
Just my $0.02

St 45
I have somewhere around 16 of theses. That is all that I run in my profiles. The carb is alittle had to adjust. The spray bar assemly rotates to adjust the mid range.
Rpm's I'm getting the following on some of mine.
st 45 tf 11x4 wood prop with an mcp 15,200
apc 11x4 old style muffler 13,800
the oldest st 45 I running is around 5 yrs old and has an hard life, it turns an 11x4 acp with mcp around 13,800.
I'll do anything with my plane and I don't worry about the motor quitting. I fly low and in close.
Email me if you need some help setting it up and I will try to help if I can.

I just found a good deal on it...Deal is not set in stone, so I wanted to see what you guys thought. I don't have an airplane for it yet...
I've had about 15 Thunder Tigers, a couple Magnums, Webra, Enya, O.S., Saito, YS, and SuperTigre's are just one more engine I have not tried yet.
I've seen many people having trouble with them, but it just seems like these guys came from using O.S. engines that never needed any kind of adjustment.
Seems like these things don't like big props and like running fast...I might try it on my Sledge just to see what it's like. I've got some 11x4's to try. Will an 11.5x4 lug it down too much?
If I don't like it, I hope it's easy to unload these engines...
Thanks a lot for the replies! I appreciate it. propnut, thanks!

Mine ran real good w/ a 11.5X4 on the ST45, when Propnut set it, but when the seasons changed my carb was out of adjustment, and it wouldn't hover worth a dang. I couldn't get it set back to perfect like propnut.

I would say any super tigre will compare with a jar of dead bugs. Some of them have ok power but they all have crappy throttle response and are heavy and die all the time. I would put ST even worst than magnums and MDS

I am not sure why their are the bad comments. I got a 3 year old ST45 on my Magic 3D turning a 12.25x3.75 prop and she flies great. The engine has a Bisson Pitts muffler and weighs exactly the same as an MVVS .40 I had on the plane. They do have a rather large carb, but it runs great and seems bullet proof. I actually really like the ST engine.

Just to put my 2 cents worth forward... Force 46BB is an awesome engine. Goes like the clappers, has fantastic throttle response and...the best bit.. only costs $165.00 AUD.

ost people don't know that sST has 3 adjustments. High, low, and mid range.

to all those that don't like ST's I say learn to set them up. propnut1 has got it right and knows what he's talking about. 3 years ago on another r/c forum AnnMarie Cross from hobbico addressed this problem and gave the proper setup for ST's. I have 4 ST's, a .45,a .61, a 2500, and a 3000. I LOVE THEM ALL, and the all run fabulous. I would rate them as good as an OS, just a little less expensive. If anyone wants the ST set-up form AnnMarie Cross, drop me a line. I have a copy in my computer.

The setup goes something like this:
A.Remove carb and piston and finish filing smooth the burs left from crappy manufacture.
B. Add perry pump.
C. Remove whole carb and replace with perry or OS carb.
Replace muffler with lighter, fewer piece muffler, this also helps to have less parts to fall off in the air.
D. Use OS plug, all the st plugs were crap, even the st lovers will tell u this.
E. Tune for low end and high end, you will NEVER get a good midrange.
F. Use a good lightning bug grease on the moving parts, as much friction as there is youll need the extra lube.

I'll been running them for 30 yrs and didn't know all this stuff that you need to do to them. Do you think the ones I got NIB I should do this to?

I apoligize to all. I apairently lost the set-up when my computer crashed awhile back. I do have it memorized so here goes....
1) remove carb and view from bottom throat. The diamond shaped venturi in the spraybar should face directly down. If not loosen the 2 screws that hold the spraybar and rotate until straight down
2) Set both high & low end needles until the ends are just barely visible in the diamond shaped venturi. This is a very rich setting. When you run the engine you will probably need to start it at 1/4 - 1/3 throttle.
3) Reinstall card making sure to get a proper seal with the rubber o-ring
4) Start engine and advance to full throttle. Adjust HIGH END NEEDLE to peak RPM. Back throtle off approx. 1/4. Adjust LOW END NEEDLE until peak RPM. Keep backing of throttle and adjusting LOW END NEEDLE until you are down to a good idle
5) After idle is set, work the throttle to check the transition. to lean out the midrange and adjust the transition, loosen the 2 spraybar screws and rotate the spraybar(only a little at a time). After tightening the screws, run the engine again to check it all. If the midrange still needs adjusted just remember to make small adjustment to the midrange until your happy.
Yes this set-up does take some time, but has worked flawlessly for all my ST's. I've also used it on ST's for other club members and they've love the way they ran after tis set-up.
This sould work for all those guys having trouble with there ST's.
For those who bash ST's, don't talk what you know nothing about and go by another brand of engine

I have a TT46 Pro that runs an 11x5 prop at 14,500 (much to the disbelief of the OS users at my club) and will run forever off fumes in the tank. For the money, It would be difficult to sway me to OS. I have no experience with the ST.

MPJ's posts?
I checked the profile on MPJ as I was curious as to why he no longer supports RCU. I discovered the listed homepage, torqueroll.com, is more or less a copy of RCU! I wonder what's the story behind this?

There's always a story...
What I like is the guy is so anal he went back and edited every single post he had to say "No longer support RCU".
