dominator / super tigre - 10/2/2004 5:43:56 AM

Hey guys, I am building a dominator with a Super Tigre .40 to practice with and maybe try some 424 in the future. I wanted to see how you all rated the supertigre for 424, because everyone seems to be using the TT .40. I really like super tigre engines, so I just went with that. I am also curious about engine mounts. I was thinking about using aluminum or laying up some carbon fiber for an engine mount plate to bolt directly to the backplate of the engine with the back plate bolts, and then to the firewall with four bolts outside of the backplate. Do they have these pre-made? I would like to be able to easily switch engines in planes and this seems like an easy, streamlined way to do it. I would also like to know what is the best way to do the trailing edge. On the last wing I tried to do I shaved the triaing edge down to a razor and the balsa was way to flimsy. I was thinking about maybe using hardwood or some thin carbon fiber rod to sand to. What methods would you recommend? I appreciate the help.

Joey

There are backplates made of alluminum similar to what you are thinking for use with carbon fiber. I really don't think the carbon fiber would hold up...

check www.lcsperformance.com Lewis has some backplates for sale like you are looking for. Not sure if they fit the supertiger or not, but worth a look.

As too your trailing edge, since you are sheeting the wing, there are a few things you can do. The easiest is to take a piece of 1/64" ply about 3/4" wide and lay it up, under the top balsa sheeting when you put the skins on. Then when it dries, you can sand down to the ply and get a nice, stiff trailing edge. Or, if you want to use carbon fiber, you could do that also. I have tried one layer of .007 on the top only, and it worked ok. I think a layer of .005 on top and bottom would probably work better.

Joey,

The Super Tiger .40 is a fine choice for 424. True, the TT .40 is more popular and it has been shown that it spins the APC 9X6 a bit faster than the Super Tiger--BUT--I feel the Super Tiger is a more reliable and user friendly motor. The Thunder Tigers have been known to ingest their carb barrel springs. Besides, if you're familiar with Super Tigers and like them, then your choice makes even more sense.

A big key to successful racing is finishing every heat. It's hard to finish a heat when your motor eats itself.

The TT Pro .40 will have speed advantage over the Super Tigre .40, especially on the long course. If speed is what you want, go with the TT Pro .40, but if you just want something more reliable with slightly less top-end speed, stick with what you already knows.

In contrast to what John said (Hi John), I've never had any problems with the three (3) TT Pro .40 I had when I first started racing in 424. Although, I did see several people had problems with them. I think the key thing for me was that I tighten every screws up, sealed and silicone the muffler together so it doesn't leak or vibrate loose. I must be the lucky one because it works great for me and I have no complains.

Just food for thought!

I was going through the ST/TT .40 choice too. Then I figured out the ST is a ringed engine. I think I heard rings are not as good at making high RPM power. The ST .45 is ABC (no ring) that is what I have on my Viper right now, until I buy a TT .40.

Unless you are flying against very experienced racers who have Thunder Tigers and who also probably fly 428 and/or Q40, you CAN be competitive with a Super Tiger. It always comes down to the thumbs.

I remember one heat several years ago I lapped three planes with a Super-Tiger-Powered Kwik-V-III. All three of the other planes were powered by Thunder Tigers and were all turning higher RPM than my Super Tiger.

Fly a tighter course.

But don't cut!

Hi Sam-Good on you!

I was at a fly in today and saw one of these things go, I must admit I am thinking hard about getting into this.

Think again vicman, you may wind up being as addicted as the rest of us race junkies.

There simply is nothing like four planes coming in tight around two and three.

Thanks guys, I appreciate the advice. I only have one problem and that is that I am building a dominator and it uses T.E. stock for the back of the wing, which poses a problem for laminating the 1/64 ply or carbon. How about sanding a recess on the bottom of the wing T.E. to inlay some 1/64th and the just sand the top to that? I know this probably all sounds like overkill but I am really picky about the T.E. Also, has anyone tried the GMS .40, or the new Norvell .40? Just curious, the Norvell is supposed to be really light. Any advice on building the plane or any hints tips at all will be greatly appreciated.

Thanks, Joey

honestly, I would not go to all the trouble on the TE at this point, for this plane. After you get the TE sanded as sharp as you would like, you could drizzle a little thin CA along the edge to help stiffen it up.

Thanks Dave, I might just try that, maybe I could find some hard t.e. material to start with also.

Back in the days when we routinely built planes with trailing edge stock.... I used to sand the edge down as sharp as you like and if it was a bit weak(very likely) I would glass the last 1-1/2" with 3/4 OZ. You can also use a drill press and a 1-5/8" dremel saw to slot the center trailing edge and insert a 1/2" strip of 1/64" ply to create the hard center sanding edge. Use double sided tape to create a rectangle out of your two pieces of trailing edge stock. Set the blade height for the center of one... slot it... flip over and do the other edge.

Both of those sound like pretty good ideas, I might have to try one. Thanks

Randy Ritch at Ritch's Hobby in Houston has 2 1/4 square back plate mounts for the STGS 40.

Thanks ddavison. That will help a lot. Is'nt that the same guy that makes ritches brew? Sam Snyder told me to go to him for some custom blended fuel.
