That's because it's made of rubber and gasoline eats rubber over a period of time. Others are made of polymers that resist the effects of gasoline. That's not to say that you can't make a black polymer stopper but you would be hard pressed to make a rubber one other then black. The black stopper Toymaker is using is for gas according to the manufacturer.

EXCEPT that the Sullivan "black" stopper is BIG-TIME *N F G*, for sure. It loses TINY parts of itself over time, and that little crap goes exactly where it can do the most interference to a great running engine; the Walbro carb screen.
Has happened to me.

The only stopper for gas I trust now is the DuBro "brown" one. But that may just be my experience only.

See Bob, that would be the point where I contact Tower and Sullivan and we start talking about compensation.

when is dl going to come out with another engine

I ordered a Bisson wrap around muffler from Horizon Hobby in early November when when they were back ordered to early December. They are now back ordered until January. Does anyone have an opinion on the JTech wrap around muffler? Do they effectively reduce the noise without a huge impact on performance? Any other recommendations?

Yes. I've used the J'Tec. The standard does a good job, the "quiet", with a significantly larger canister volume, quiets things even more, but the cost is BIG MUFFLER. Lots of cutting of cowls, etc.

I thought the J'Tec standard Pitts was pretty good. Definitely MUCH quieter than the stock.

Sorry I didn't know? oops?

That should have been a PM. NO SELLING IN FORUMS!!! You need to edit that post before we get locked down.

Afraid of loosing another virtual place to live? Hehehe.

No, actually, I don't know if you've taken the time to notice but everytime this thread gets locked we lose more experienced people. They just don't bother coming back to it because they figure it's a waste of time. Once the knowledge base is gone the inmates are in charge of the asylum and the thread becomes pretty much useless.

Bob,
Is this picture the standard Pitts you are talking about? It came from the J'Tec web site.

Can someone tell me what the definition of a "Pitts Muffler" is?

Chuck

CHuck - those are the "side Inverted" mufflers. The "Pitts" is normally configured to "wrap around" the cylinder, engine inverted, such that the canister is cross-ways under the engine box, and the exhaust tubes point down near centerline of the fuse, and cant slightly rearward.

Pic attached is NOT a DL 50, but is a good example of a bottom view of a Wrap Around PItts-style muffler.

who sells a good header and canister for a belly mount?

bob, i was reading some on your site, you can run 2s lipo on ignition now? i have the 2.0 ignition but it said 4.8 to 6.0 volts......

xracer

Nope, not that I'm aware of, at least not without dropping diodes. The "2S" that I'm referring to is a 2S A123, which is nominal 6.6v. That's the setup I'm using on both of my DL 50's, each with version 2.0 Rc Excell ignitions.

Probably the "best" US source for this is Desert Aircraft, buy accessories for the DA 50, they will fit perfectly.

ok, sorry, i know about the a123 alittle pricey and heavy too, but really good battery, tried one my electric plane, wow what a discharge rate.

xracer

ok, thanks bob, i will take a look,

No prob! The only reason I'm using them for ignition is because I have an extra output lead on the single 2S Rx pack (5.6 oz) that I route to the ignition switch. Since I'm using Spektrum AR 9000's and AR 7000's Rx's, they are just dandy with this setup. No interference, and I was surprised at how little extra mah the ignition actually pulled. So I actually have shed some ounces by doing this.

Some are running a single A123 cell for the RC Excell igntiions with good results, too. That's only 2.8 oz.... and the 2300 mah capacity means it's a charge it once a month kind of thing....

Lots of options!!!!

you know thats sounds like a good deal to me....

just bought 2 new packs or i might look into that, maybe for my patty im about to start on i will do that... thanks

xracer

arent the single cells just 3.3 volts?

Hi guys,

I have been following the threds and if I may suggest,

I like to use lion batt with a regulator for my Rx and my ignition as well, I buy them from Troy built models Inc. They have lots of good electronics for airplanes,

Yep. Still work just dandy. There's a thread in this forum about "A123 Cells on Ignition".... lots of good info there. josey wales is running the single, and also has used (as I have) a 2S with dropping diodes to get to 5.4v so non-Rc Excell igntiions won't fry.

Bosco2 - you are correct, Troy Built has lots of good electronics accessories, but the disadvantages of LiPos for me made up my mind to do the A123. Once I did, it was over for me. They (the A 123) are really outstanding batteries with none of the risks from handling errors, and easier to manage charge/discharge with. To each their own; I know there are THOUSANDS of lipo users out there happy as a clam.

I like the A123, and enjoy "testing" other ways to skin all of these cats in our hobby.....

yes, i have a friend that is useing the ion, he has tried to get me to use them, im just hard to sway[&:] lol i really like that split regulator with the fan on it, smart fly i think...

bosco did you get my p m ?
