hmmmm ... be sorta hard to trash one if you crashed in 3 foot of snow!

Hey all. Been following this post for awhile now. It seems the DL is held in high regards in here and from what the members say about the customer support, it seems first rate and Bob seems to be a man of his word which top of the list with me. So, the one question is: I can afford the step into scale, but not twice if you know what i mean. Is this the motor for my 12-14 pound airframe that is gonna be there to fly 2-3 times a week like i typically do 3/4 of the year?Myself and my 9 year old fly and i just purchased a .60 300s for him already today so with 2 flyers in the family, each purchase has to be pretty close the first time around. Just wanted your inputs. And Bob, I wish all customer service sounded like yours, there would be alot more happier modelers in the world.

No way. This will be one of the few days that puts me into hibernation.

IS there a reason why on dlusa its says that vvrc is selling the old generation and that he dosnt support dl , i was looking through the post and tom at valley view only says good thing about dlusa am I missing something . only wanted to know because sometimes one has something that the other does not?

I know it is a long thread now, but it would be better for you to read it than to rehash that all over again.

Just a quick email, my standard muffler has broken on my first DL, vibration caused a crack to propogate around the exit tube, then it split and almost fell off (afte about 6 flights)...just a word of warning.......quite glad really, as the std muffler is DAMN LOUD! Its now happy on a KS cannister.

Man looks like your toybox is getting full!!!

0.75 Oz a Minute!! [X(] I am getting 11 minutes max out of a 20 Oz tank.....! but the motor is only one gallon old...should i be worried?

I have motor 2 on its way, so i guess i'll see if its the same..

PS: Thanks Bob @DLUSA again! for excellent service....its real piece of mind dealing with you!

thanks was not trying to start anything because i have learned alot on this thred

I got tired of looking for it,but can someone put the website address for the US Dist.in here.I tried dlusa.com and it doesn't work.
Thanks[8D]

Thanks for the website info.!

I lived in Rochester Mn a bit over 30 years ago. Had small children at the time and we had a lot of wintertime fun. Lots of snow and cold like you are having there now. I just wanted to point out that we are not imune from cold and snow here in Florida. Someone actually saw a few snowflakes in Daytona Beach this morning. (Wow!!) Not only that, long sleeves and a jacket were required for outdoor activity today!!!

Anyway, I have read just about every forum post I can find and all the spec data on almost every engine in the 46cc to 53cc size. Seems to me there are quite a few good engines out there. My net would be that if money were no object, I would buy the DA but the DL just looks like the price performer and has good support.

Am flying Aviation Models 33% Yak with ZDZ 80 but I want a 50cc size also. Have not picked the plane yet but will buy the DL.

Thanks for all the input and mostly positive thread.

Afternoon Guys,

Can someone advise me on how to tell the difference between the V! and V2 ignition system? Bought mine thru Bob last June and am thiniking of using the new 1100mah VPX pack to power the Ing., but that's to much voltage for the V1. I did see a stamp on the case that inidcates 4.8 or 6V....just wasn't sure what that was telling me exactly. It does not have the version stamped on the case.


Thanks for any help.

Mike

Bob would be the guy to tell you for sure. It was my understanding that neither of the EIs should be run on 6.0 volt and that it was a mistake by the factory but I could be wrong with that. I don't believe 6.0 gives you any benefit over 4.8 on the EIs and that companies were changing to 6.0 for a matter of convience rather then performance. Again, I could be wrong. I'm sure some of the "electric type" guys can inform you better. Here's what's on the site.

NOTE: A 6 volt or larger battery pack must be regulated to between 5.2 and 6.0 volts or it will supply too high a voltage to the ignition module.


That means you have to have a regulator I believe as the 6.0 volt packs charge slightly above.

This isn't accurate, completely. Bob Kramer is doing the "warranty" on the ignitions, with support from DL factory, who probably has to warrant through Rc Excell.... so they are being cautious.

I did the A123 testing of the version 2 for the RcExcell factory, and they made internal modifications for it (v.2) to be "okay" with the A123, unless prolonged running above 8000 rpm. In their instructions, they clearly recommend the use of a diode (or two) to drop the source voltage to within known "acceptable" limits, no matter what rpm. That is their warranty statement, and conditions.

The *fact* is that the v.2 works totally satisfactorily on un-regulated A123 voltage, which is 6.6v, considering that the peak of 7.2 lasts literally for less than a minute or so of cycling servos, etc.

Since I'm not the guy warranty-replacing the components, my comments should be considered in that vein.

BUT - I worked directly with the president of RC Excell on this testing.... and I am currently using two v.2.0, one of which is a "DL" labeled unit, on un-regulated A123 voltage. Although I like to "push the envelope", I am not stupid and will not do things that my experience and logic tells me present unreasonable risks.

Just to be clear - I am *not* telling everyone to go run unregulated A123's on their v.2 Rc-Excell ignitions. That is not my place to tell ANYONE what to do or how to set something up. But I will, and do, share my experiences FWIW.

If not worth much, disregard.
If it sounds like "Hey, that's pretty cool, I think I'll try that", then have FUN!!!!!!!!!!!!

I think you would be happy with a DL-50 engine, I have one on a hanger 9 extra 260 and it's great. Unlimited vertical (I think, gets too hard to see to keep going up) Just be aware this will be an insane monster on a 14 pound plane and could tear a 12 pound plane apart. This engine will 3D 16-17 pound planes with no problem at all.

Under perfect conditions the engine is capable of nearly 30 pounds of thrust.

If you don't want to stray from the manufacturers recommendations you could just throw in a diode as discussed it this thread:

http://www.rcuniverse.com/forum/fb.asp?m=6782216

A single silicone diode will drop the voltage by ~0.7V, and the A123's voltage will drop to ~6.6 volt very quickly, so you will be below 6v for everything after the first 30 sec. of flight.

Thanks Guys for all the information, I'll be heading over to the other thread to take a look at how there setting everything up.

So it is probably best to send off an email to Bob and see what version ignition I have. Just thought I was mising something easy to tell the difference.

Thanks again,


Mike

Are any of you challenged by getting the CG just right on your plane? I just finished building the Venessa CG machine (see http://www.rcuniverse.com/forum/m_70.../tm.htm#708060). It works great and it's easy to build.

Here are a couple of pictures of my DL50 equipped Extra 300 on the Venessa. You can't see it in the pics, but the plumb bob is showing that it is balanced just aft of 3 inches belind the leading edge at the wing tip. Book calls for 3 to 3.5. As this is a preliminary balance job to get me in the ball park (and I don't have the muffler mounted yet) I expect that I will have to move the throttle servo back near the CG. Right now it mounted inside the engine box.

In any case, I thought this was a very helpful device and wanted to share it with those of you might be experiencing challenges balancing large airplanes.

Aerobob---This might be something to add to your tips 'n Tools page. I found it very helpful and easy to use.

Rich, that is a very good method. Good suggestion to put it on my website; never thought about it. Thanks for nudging me!!!!!!!

There is a sticker on the side of the module that will have the v. number on it.

Hi, I just put my first DL 50 in a Great Planes Yak and I have a question about the four-bolt prop retention system. Do I need to Lock-Tite the four bolts?

No, you want to tighten the bolts run the engine and re tighten the bolts after running the engine.

Thanks.
