RE: Echo 2400T Short blocks
 

Seems like someone should know about left-hand threads! How about it!!!!! Capt,n

RE: Echo 2400T Short blocks
 

I sent my Left hand thread 23.6 to Roy Sholl to see what kind of hub and prop adapters he can come up with and maybe his ignition system.

oldtimer2: I sent you a privite e-mail. Capt,n

RE: Echo 2400T Short blocks
 

Hey guys, I have a box full of new flywheels and coils for those little Echos. Some are aluminum and some are plastic. How about 10.00ea? We converted them years ago and wrote a thread about hot rodding the 23.6cc called "Dont forget Echo".

RE: Echo 2400T Short blocks
 

Don't need the coils.... how about $15.00 for two aluminum flywheels? (I cut out the centers and use them as "backers" for screw on magneto type prop adaptors.)

I sure enjoyed that thread we did on "Don't forget the Echo" and thanks again for your help/advice. I've got two of those 23.6 cc engines flying and they work great. One of them is the stroker version. More are in the works when I get around to them...

Thanks,
AV8TOR

RE: Echo 2400T Short blocks
 

oldtimer2 How did the engine with left-hand threads you sent to Roy come out? Did you get it back yet/ Thanks Capt,n

RE: Echo 2400T Short blocks
 

Hi Captinjohn,

He finished the hub, I should get it back next week. I will post a picture wnen it arrives.

RE: Echo 2400T Short blocks
 

Pictures please. I have a few of those engines to do. I have an idea to deal with the LH threads but I would like to look at his ideas too.

RE: Echo 2400T Short blocks
 

I received the engine back from Roy at S/S Machine & Engineering today. He did a very nice job on the two piece hub. Now I need to start working on getting an ignition or an adapter for a glow plug.

RE: Echo 2400T Short blocks
 

Wow very nice. Looks like he utilized the LH thread. Never thought too hard about that idea. I guess if you Loctite the hub on you would be OK. I'll be thinking now.

RE: Echo 2400T Short blocks
 

Boy....Thats no 5 minute job!!!! Sure looks nice. Let us know how the Hub works out. Capt,n

RE: Echo 2400T Short blocks
 

I had to relocate the position of the pulse switch on mine to fit the Funtana. The way I did it originally, the sensor was rubbing on the top of the cowl. Gotta get in there and make a throttle arm/linkage. As pictured, the motor weighed 2lbs, 2 oz.

RE: Echo 2400T Short blocks
 

flipflop: Is that a seperate ring that has the magnet in it so you can set timing? sure would like to see a photo of all the parts of hub assy set out in sequence. Thanks Capt,n P.S. The work looks very well done.

RE: Echo 2400T Short blocks
 

FWIW I have been using the small arm that comes on some throttles and a ball link. Works great. Just a little expo and it is ready to go. What did you use to attach the sensor to? Looks to be mylon of some sort. Capt,n that is a timing ring and I do mine that way too. Easy to time.

RE: Echo 2400T Short blocks
 

The block that holds the sensor is just some sheet nylon (plastic cutting board from Wal-Mart would work just as well) Here's the throttle arm I made. The stock arm on this carb was a little to small for me, I wanted to keep the choke/fast idle feature of this carb so this is what I ended up with.

RE: Echo 2400T Short blocks
 

You sure have some nice work pictured.
1) Do you use more than a single setscrew to hold it in place?

fllipflop: What securement for the white nylon sensor mount?

RE: Echo 2400T Short blocks
 

Well, I thought that photo would show it well enough. The nylon block is held to a small aluminum angle bracket with two 4-40 bolts. The angle bracket is held with the front cylinder bolt. For the block, drill a hole the same size as the OD of the sensor. Then make a cut with your bandsaw from the edge of the block to the hole. Instant clamp when you tighten the 4-40 bolt. I'll try to get a better photo.
On the timing ring, with the magnet say in the 12 oclock position, I use a setscrew in the 8 oclock and 4 oclock positions.

RE: Echo 2400T Short blocks
 

flipflop: thanks for the clarification. Your handiwork is so finished I missed the angle stock on first viewing. It is plainly visible once you know what to look for? ;) The instant clamp cut shows fine once you know what to look for.

I have drilled and tapped VHMW and cutting board with good success. Tapping the front section of cut side might be a way to eliminate the two 4-40 nuts on the face. a gram here, a gram there.

RE: Echo 2400T Short blocks
 

flipflop: Did you lower the compression on this engine. It appears to have a quite thick base gasket under cylinder base? Thanks capt,n

RE: Echo 2400T Short blocks
 

Nope, that's all stock Echo just the way I received it. Good picture makes it look thick. If I do anything, it would be increase the compression, not lower it.

RE: Echo 2400T Short blocks
 

Yupper...that what I woud do to...raise the compression. Best Regards Capt,n;)

RE: Echo 2400T Short blocks
 

Finally got a little cooperation from the weather yesterday afternoon, got three flights on the little Echo in the Funtana. It took me the first two flights to get the carb adjusted just right, the last flight was pure fun. Right now I'm running an APC 17x6 on it and this seems to be about a perfect combo for a small gasser. The motor is still far from being broken in, but it will hover right now with a slow pull-out (still just a little rich on the high needle) The G-26 that I had on it before was WAY too much power (unless all you like to do are bottle rocket verticals) Now while in the air, I can concentrate on flying instead of worrying about overspeeding the airframe and having it flutter itself to death. I haven't weighed it yet since I changed motors, but the Echo is lighter, I moved the receiver battery forward 5in. to achieve the same balance point. Sure hoping for good weather again this weekend...

RE: Echo 2400T Short blocks
 

flipflpop: Sounds like you got a neat combo there. I may have to do that set-up also. If you can...post a photo....we all enjoy your nice work! Capt,n

RE: Echo 2400T Short blocks
 

flipflop
I'm pleased the maiden on this engine went well. What neat muffler/exhaust diverter did you end up using? That one on the test stand would looked huge but practical for the stand?
Which Funtana 90 or 100X?

RE: Echo 2400T Short blocks
 

Mine is the Funtana 90, the 100X should be even better. I'm using the B&B muffler that I had on the G-26 (had to modify the bolt spacing just a tiny bit) I'll get some photos later.
