I don't remember who it was that posted it, or where, but pretty sure that headache is history.

Just checked Tower - looks like they're giving mixed messages on the EI voltage. Looks like they're saying the old EI's require a voltage regulator for greater than 6v sources, but the newer EI's do not.

- 4.8 - 6V NiMH/NiCd, or 6.6V LiFe or 7.4V LiPo battery for ignition (separate receiver style pack can be used) (LiPo & LiFe requires voltage regulator)


- Ignition Battery: 4.8 min, max as marked on electronic ignition unit. If marked 6V max, BEC required if LiPo battery used. Newer ones may be marked 4.8V to 8.4V.

It appears that new DLE20 engines being sold come with a new version ignition module. The newer version (A-02) is labeled to handle up to 8.4 volts, compared to 6.0 volts on the older version.

Some people have said that the newer version has also gotten rid of the timing curve (step) that the old version had. Can anyone verify that as a matter of fact. I haven't found anything from dlpower.com or dleengines that confirm that has happened.
A short while after I asked the above question, it occurred to me to call Tom Denny at Valleyview RC. Tom said the curve (step) has been removed from the new version module.

So this new version of ignition module for a DLE20 doesn't have the issues of the older version and can handle up to 8.4 volts. That's a very nice improvement.

Super photos; they really help! Did you double the firewall or did the plane come that way?

The step in the timing curve was cured a little before they changed to voltage up to 8.4V. I bought 2 ignitions from Tom last fall, they have the new timing curve, but still only good for 4.8 - 6.0V.

Anyone know what size prop shaft thread the 20cc XYZ has? I'm trying to get a spinner for it. I think it is a different size than the DLE 20cc. Thanks a bunch!

Hi, Ernie, Mike here. The early VVRC 20's had an odd-ball metric thread. The current versions like mine use the same thread as the DLE 20. Tom can tell you what the old thread was. (I don't remember at the moment)

It's a lot of fun to fly. Goes where you point it, does anything you ask of it. I let Tom Denney fly it today, and I don't think he wanted to hand the radio back to me! Here are some pics of it.

The ARF came with mech. retracts, but I used a set of HobbyKing electric retracts and so far , they've been flawless. About 13 bucks for the pair. By the way, the airplane weighs 8lbs, 10oz. dry. APC 15-10 prop on the VVRC 20. Never tached it.

Hi All

I have a throttle arm extension for the DLE 20 carb . It is a CNC version 16mm across and raises the arm about 12 mm

The only manufacturer ID seems to be RCB.

The hole at the end of the arm is threaded . Does anyone know the thread at the end of the arm is please?

The prop shaft on the XYZ20 was 8mm x .075. The latest batch of engines now are 8mm x 1.00 which is the same as a DLE20 according to Tom Denny of VVRC.

Thanks for the crankshaft tread info Mike. Another carb question - anyone know if the carb can be turned 180 degrees? Or if the throttle arm can be reversed in the carb? (on the DLE or XYZ (walbro). Just wondering, thanks.

I don;t know what you mean "reversing the throttle arm", but the whole carb can be turned 180 degrees on the DLE 20

Thanks. If you can reverse the whole carb, no need to try to pull the throttle shaft out and reverse that anyway.

I have a spare DLE 30 ignition set and wondered if it has the same timing as the new DLE 20 ignition. I understand that it may require a regulated voltage, I am just curious about whether I can replace the DLE20 ignition with my spare DLE30 ignition. Thanks.

Wouldn't be my first choice, but if the price is right I'd sure use it?

The DLE 30 module has the same type "step" timing curve the infamous DLE 20 #4's has/had. The difference, the reason it wasn't so problematic, is that the step occurs at a much higher rpm - something around 42-4400 if my memory is working properly. Bottom line is it works fine. 99.999% of flyers would never suspect anything is different about them.

I am sure this question has been answered somewhere in this long thread, but the crappy search thread feature doesn't help much.
My question is " How does power of the the DLE 20 compare to the YS 120 FZ"?;
I am thinking about replacing my YS 120 With the DLE 20.

Thanks in advance,
Greg

For power comparison, maybe check out what guys are using for props on each? 16x8 and 17x6 are both pretty commonly used on the DLE. They'll turn up into the 8500 (+/-) range, but one guy says his is working well on an APC 18x6W? I plan on trying that one soon.

You'll get a higher top end with the YS120 than a DLE20 in a dive. But the DLE20 has much more power to get you to speed
