What engine and prop is being used for the Lanier Slasher Combat Kit .30? I have many engines in the 25-40 range I could use.

How is this bird doing in the Class Open B combat?

Jim,
If you wish to fly AMA/RCCA combat the max engine for the Slasher would be a .30. Most contest fliers use OS .25FX, Irvine, Webra .25 GT, Magnum .28, Jett .30, or Norvel .25. Almost all use the mousse can muffler system from www.flyingzhobbies.com to extract another 2,000 rpm out of them. The favored prop, used almost universally is the Master Airscrew 9X4.

I haven't seen the Slasher in an Open B event yet but the Ripper, its SSC Sibling placed 2nd among 26 pilots this past weekend at the Hilltop Valentine Massacre in NE Atlanta.

Good luck.

If you want to use it in B class combat, you need to use a .30 or smaller, obviously.

In B class, you have a number of strong engine choices. The most popular is the OS .25FX because of it's solid power and high reliablity.

I use the Magnum .28XL in B class. It has power, but it's carb is tempermental.

If you want to spend a lot of cash, you can get the Jett .30, though nothing I've seen indicates that the money buys you anything over the OS. They are durable, powerful, and reliable though.

Norvel makes some quite powerful .25 engines, but they are tempermental. Guys who know how to make them work get great results from them. Guys that don't, miss a lot of starts.

Irvine is also popular, reliable, and quite powerful. I don't know much about them (though it looks like I might pick one up soon, so ask me in a few months how it comes out)

As for the plane, while I might have flown against one here or there, it doesn't come to mind, and it's not what the top guys are flying. I think you could best describe it as a good-looking design that hasn't really been pushed by a top pilot yet. It might be more popular in other areas though, so I don't know for sure.

hilleyja,

Let me know when you get your slasher ready!!! I just built my Ripper and it flys great!!! I cant wait to fly it for combat this season.
As for the moment im using the os 15 cva with the stock muffler and it runs great. Granted the motor is still new but ive always been using os engines for my cars and my planes. quality for cheap!!!

I'm also running the OS CV 15-A in a J&C FunBat. I'm at 1/2-power while all of the Magnum 15XLs and other 15s are at full power. It is an awesome engine for its size.

Two questions:

1. The manual for the Slasher says 2 1/4" - 2 3/4" back for the CG. "Back" from what point? The leading edge of the wing?

2. I went the cheap route and got a GMS 32. I ran it for the first time last night and all went well...considering the price and country of origin. The problem is you can't shut the thing down from the radio! Who made such a silly engineering move and why? All combat I've seen to this point, the folks shut the engine down before touching down...any options?...or do I just stock up on props and plow the field on landing?

Yes, the CG is measured from the LE of the wing.

If you're just flying the plane for fun, it doesn't matter much if you can stop the engine from the radio or not. But, strictly speaking, contest rules usually require the ability to kill the engine from the TX.

I've heard that GMS considered the inability to kill the engine a "feature", but it just seems like sloppy tolerances to me.

You can often fix an engine that won't shut down by sealing up everything in sight with RTV silicone. Esp the backplate and carb.

But, if you're flying off grass, and you use the black MAS props, you can land with the engine running and not break the prop, I do it all the time. You just idle all the way down, and come in at a really flat angle, and slow the plane way way down before touchdown. You'll kick up a little grass, but you can do it with out breaking the prop.

Thanks...I'd heard about the RTV trick with GMS engines. No contests in my near future so i'll leave well enough alone. The .32 doesn't play fair anyways.

If things get serious, I'll look into a respectable piece of metal, like a webra or an OS...or what about those old BB enya 30's plastered on the pages of eBay?

If you're not flying class, or if you have a good poker face, the new Thunder Tiger Pro .36 is the same exact dimensions as the .25, only bored out slightly. This not only gives it more power, but it is actually lighter than the .25. My buddies Slasher with this engine and a mack muffler tears up the sky.

Be sure to upgrade the ply reinforcement on the ailerons where the pushrods attach, they'll rip right off the control surface.
