RE: NEW DLE30!
Excuse me if I'm comming in here rather late...but we are talking about low flow velocity in the intake "manifold" area (after the carb ) correct?
After looking at a friends engine, it appears to me as though there is too much volume between the carb venturi and the crankcase?
The fuel/air mixture wets out along the walls of the conduit, instead of remaining in a fog or mist, and the resulting droplets cause flooding, or they put out the spark at low r.p.m. (because of this low flow velocity )
I have experience with Boss 302 and 351C 4V heads...and this is my 1st impression...FWIW
If such is the case, then it seems as though a re-design of the I. manifold is necessary.

RE: NEW DLE30!
This is true, and it is eaxctly what Jody and a few others had been trying to push the manufacturer into doing. The pictured induction modification has been known of for a couple of weeks but to have revealed it could well cause the manufacturer to defer in making the required correction.
There was a darn good reason why it was not published earlier. Jody at Valley View had been working directly with DLE to encourage a manufacturer response. Thanks for the attempts Jody, but once again no good deed goes unpunished. Had someone waited instead of caving in to the impatience of the masses you might have accomplished a tremendous performance gain with the DLE 30. As it stands I'm afraid the best you'll ever see is a minor induction design modification. Looks like the 3w-28i will still be the emperor of the 24-30cc class of engines. Nice try though....
Only three other people knew what the mod was and all were supposed to remain silent. One failed.

TOM....I don't get your last post at all[sm=confused.gif]
Why would a picture of the induction modification being revealed, stop the manufacturer from making the required correction?
DLE must realize that if the correction isn't made, it would greatly affect their sales.
Who wants to put down good money for a new engine and have to go through the hassle of modifying the induction system?

RE: NEW DLE30!
I believe what he ment was they would have liked the manufacture to redesign the intake, now what they will most likly do is make a mold of the intake and have a piece of rubber or plastic made that fits inside the intake between the carb and the reeds to reduce the volume. They would be fixing a symtom not the problem by doing this.

RE: NEW DLE30!
If that is what a company like DLE would stoop to, I don't think I would want to do business with them on their 30cc engine.
I love my DL50 but this type of a fix would make this engine fall into my category of "Just More Cheap Crap".

RE: NEW DLE30!
Somewhere along the line the "DLE" Company Fat Cats got to return some of the $$$ into a new casting and whatever it takes. This DLE30cc engine has great potential if done right. There has got to be some pretty good $$ there somewhere to do it. Come on DLE , Lets get the job done right. We know you read all this...so get with the program. I hope I speak for all the people that buy your DLE products. Signed ALL OF US. http://www.ec21.com/companies/dle_engine.html

RE: NEW DLE30!
We shouldn't expect DLE to go to all that trouble. All us "buy and fly" newbie crybabies should fully equip ourselves with machine shop and fix it ourselves like "real" hobbiests of old.We should just buy metal and build our own engines from "scratch" like real modlers. 
I apoligize for the sarcasim but really tired of the "buy and fly" and similar references used here on previous posts. I have three DL50's that have run perfectly for several seasons,but if I had bought a DL30 with this problem I wouldn't dissassemble it,I would send it straight back for a refund or get payment back on my credit card. Not because I have no skills(used to custom build Holly carbs for drag cars) It's the manufacturers problem not the customers.

RE: NEW DLE30!
If a factory plastic part like tkg made fixes the problem, I would be happy to purchase this engine with the part installed. I can see this part incorporating a heat spacer flange.
Reading the manufactures statement; this not being a problem unless the engine idles for over 30 seconds and does not effect flight is a huge cop out! I don't do a elevator landings. When I land, I fly a down wind leg, cross wind and final, land and taxi back. If an engine will not allow this type of performance, I will not buy it.

RE: NEW DLE30!
So now the fix has been published, who will be the one to provide it. One post above notes he would be happy to purchase the engine with the insert already in place. OK, Who makes it? Does everyone believe the dealers will be responsible, or do they really think the manufacturer is going to provide it now they know individual engine owners can do it themselves?
Are you folks so naive to think the foreign engine manufacturers really care about you? Perhaps some of you (only a few) understand that all they consider is the bottom lines, and making a new part to fix an old problem effects that bottom line, negatively. You got shot in the foot (thanks Terry) for any possibility of an intake redesign, which would have been 50% of what was needed to take the 30's performance over the top of anything out there.
So ya'll might just as well break out your favorite molding compound and get to work. That's likely all the response you'll receive, especially considering the manufacturer's original repair proposal missed the mark by a couple of miles.

RE: NEW DLE30!
You never know what DLE comes up with. It's easier for them to change the casting for the intake to decrease volume. Only issue for customers is when they replace the backplate, the cylinder gasket can get damaged.

RE: NEW DLE30!
T.O.M. the average DLE 30 owner won't be able to make a intake stuffer, their just at the wrong end of the talent pool.
So DLE has 3 choices
1. Ignore
2. Ignore and make V2 asap
3. Step up to the plate and make a heat dam stuffer and ship it to all their authorized dealers and then make a V2.
We shall see what we will see.

That sort of agrees with the "buy and fly" principle, no?
Sorry folks, but I'm not trying to tell anyone what they want to hear, but what they need to know and understand. The two aren't always compatible, but are generally necessary.

RE: NEW DLE30!
Well this news made up my mind to call Valley View and see what their reply is. I have the engine still in the box and have not even put it on a plane yet maybe I can send it back. I hope that DLE will do something to just fix the intake and send the part. I've got lots of tools.
OH and yes I"m a gambler anyways so I do'nt whine or cry over the small stuff.

JB Weld?[:'(] I always get a good laugh when I hear someone talk about this miracle epoxy. I have been a Federally Certified Journeyman Machinist since 1990 and was a general uncertified machinist starting in the trade in 1978. Got tired of being a "Factory Rat" and quit my job to go to Trade School and serve an apprenticeship for 4 years in the aerospace industry. JB weld is an adhesive. It is a darned good adhesive but it is not "metal in a tube" but don't listen to me....go ahead and mix up a batch and put a big old glob in your new engine. I always put a glob of JB weld in all my new R/C engines including my wife's new Cadillac!! I apologize if some of you do not take well to my sarcastic humor but I really wanted to buy a new DLE-30 but decided to wait and let others be the guinea pigs. I just bought a N.I.B. Webra Bully 35cc. I will have some machining to do on it to convert it to a new RCExcel ignition module but I can assure you that I will not use any JB Weld.
Hey Captinjohn, I am sorry I got under your skin with my PM. You know... your reply with the ***** asterisks! I know you are involved in these forums to help and I appreciate you taking the time to direct me to other discussion forums on the DLE-30.

Unfortunately it is the easiest fix that will work, and should last a fair amount of time. You could CNC a nice piece, but that is expensive and out of reach of most.

You can also use polyethylene w/ a melting point of 115 degrees C, or polypropylene at 160 degrees.
Try at your own risk
