Was eyeing the DLE20 for one of my airplanes but a couple of sites show it as discontinued. Is that true?

Also any data on the OS 33cc gas engine?

Still a few at Tower Hobbies. But it also says limited quantities.

DLE stopped selling to non authorized dealers to keep better control on price and customer service. Thats why Hobby King and others show it "back ordered" or "discontinued". Just order one from Jody at Valley View RC and your good to go.

Just got mine from Tower

ameyam

OK, I get it. Point is Tower is very expensive. One of these sites had the DLE20 for $190 odd where as Tower is offerring for $279. BTW, Tower list them as available in limited quantities.

They have alternative makes though. One that caught my eye is RCGF and they have a 20cc, 17cc and 15cc model. As per the RCU research pages, this is a good engine. How is this make and how do these gas engines compare with the say a 95ax or 120ax?

I was planning to get a 95ax (or use my 120ax) on a Phoenix Extra 330s 64" and was wondering whether to get any of these or wait for the OC 33cc engine and put it on my Funtana / AW Yak 90-120QB later

you almost gave me a heart attack there man.. i just bought one and i've not even received it yet and im seeing discontinued??? gasp!

I too would like to know how the other variants of this engine compares

MetallicaJunkie

if you are worried about paying 280 for a DLE 20... you will be shocked to see the os 33 for close to 500 dollars......DLE 30 gets my vote

ameyam

I am not worried about paying either price. Typical Indian mentality- we dont mind paying more if there is better quality to be had. That is why I didnt talk about the price in my posts.

I noted the DLE30, its $320 from Tower, Singapore hobbies may be cheaper. If I get it, I intend to use it on either a Funtana or AW Yak 120QB.

Anyway, the 30cc is a bit further away. In the interim I was planning to setup a Phoenix Extra 330s 60-90 64". Initial plan was to set up with a 120ax but I feel that it would be too heavy and was looking at the 95ax instead. However, I noted that a number of makes (RCGF for example) have gas engines in 15cc - 17cc as well. Therefore I was inquiring regarding these other makes. I intend to use a common RX and ignition battery (LiFe 3200mAh Hobbico). Can anyone guide in regard to the make and the battery configuration? Please suggest regarding the power, I intend to 3D the airplane

must be nice paying 10 cents a gallon for gas

ameyam

.

Sorry I couldnt reply earlier, had conferences all day.

We dont pay 10c / gallon. What gave you that impression? The price for ordinary gas is about $1.4 / litre. In other words about $7 /gallon. I think the US rates are lower. But still lower than the $40 / gallon for synthetic glow fuel

I would be very careful with a price that sounds too good to be true. There are a lot of fake DLE engines coming out of China. It may look real on the surface but it necessarilly a genuine DLE.

I can see how buying from Tower could be expensive due to the international shipping costs. You might inquire with DLE and see if they have an authorized Indian distributor or at least one that is geographically closer to you.

hi-models.com. Thats the site I was referring. Anyway, they dont have dle only rcgf now

I can always get dle from Tower or Singapore. The question is no longer where I get it from but rather whether should I put a 20cc engine weighing 820gms or a 95ax wieghing 745gms or a 120ax weighing 840odd gms or a RCGF 15cc weighing 825gms on it. The airplane in question is a Phoenix Extra 330s 60-90. I know 3d airplanes require light wing loading but does the 95ax have sufficient power for this airplane? Also, I am much inticed at the cheap price of gas over nitro

While I've had no problems with RCGF engines, bare in mind that the DLE's ( and most American, German or European engines, eg. Desert Aircraft, 3W, ZDZ etc. ) produce far more power than the RCGF's or other Chinese engines do, by weight and displacement.

ameyam

But is the aircrraft suited for the engine and vice-versa? What I am asking is do I put a DLE20 on the Extra instead of the 95 or 120?

The DLE 20 will be just a little more powerful than the 95 with the extra weight being the trade off. The 120 pulls about the same as the DLE 20. But the real question/difference is, $3.50 gal gas with little to no clean up or $20 Glow with lots of Windex and paper towels.

Oh ya, the 20 will use 1/2 - 3/4 ox per min of flight compared to 1 - 1 1/2 oz per min. Do the math on that one. [8D]

ameyam

So that means the 120 and the dle 20 are comparable? Then it makes sense to go for the DLE

Ameyam

It largely depends upon the plane you will be install the engine into.

- Is the airframe strong enough to handle a gas engine? Or was it designed for glow?

- Is the extra weight of the engine and ignition battery going to affect things like tip stall?

- Can you get the engine installed w/o any problem? Run the lines? etc.?

ChuckW

If you think the airframe can handle the gas engine without any major instalation headaches and the small amount of extra weight won't be a problem then I would go for the DLE-20. It is compact and easy to mount in place of a glow engine and even expensive gasoline is cheaper than glow fuel.

I am in the process of installing one in a 70" revolver right now and I have another one wating to go into a Top-Flite P-40.

ameyam

The Extra 330s was really designed for glow.

I will have to use a GP 90-120 mount instead of the stock, the stock one is too soft and too small. I will also need to fibreglass the firewall as everyone does with their 50cc models for additional strength

From the weight point of view, you will have to look at what I was going to use originally- the 120ax. It is about 820gms and the DLE20 is about the same. The Phoenix Extra 330S 64" and the Phoenix Yak 64" are mostly the same airplane, the Extra seems to be more updated than the Yak. I have already flown a colleague's Yak 64" with a 120ax on board and it does tip stall mildly at low speed (for example at the bottom of a flat spin, when coming out of a harrier etc it feels like its on a banana peel, in the harrier there is a lot of wing rock) but its nothing that I dont seem to be able to handle. There are also custom SFGs some time in the future for this airplane in my planning (The model didnt come with them, the wing tips are flat)

I will mostly go with the DLE20, will order from Singapore as its cheaper. If it doesnt fit on the Extra, I have a Funtana 125 waiting for sometime later next season

my dle 20 pretty much performs the same as my 120AX and Saito 150... i use a 17x6 on them all.. if i could do it all over again i would have never bought my 120ax's...the DLE 20 beats it in the low end torque band, which makes it great for 3d flying.......

TimBle

Trust me, you don't want the RCGF15cc on an aerobatic aircraft. Maybe in a Cub or a Cessna that requires a 15cc engine but not an aerobatic plane. The RCGF is lazy and heavy. not what you want for a 3D bird.
I was out flying my World Models Spot On today. its a Pattern plane and designed for 1.20-1.40 4Stroke. It has a DLE 20 on the nose spinning the fan.
JXF 16x8 spins at 8000rpm on an engine that has barely run for 30 min. Vertical is unlimited. Once its broken in it will swing the 17X8 JXF. I am yet to see a AX 1.20 spin a 17x8 at 7800rpm.
Also the DLE is dead easy to operate. Set the needles to factory settings and go fly. After abot 2hrs of running re-adjust and of you go. The 1.20 AX is a pain. Change the prop and back to the engine tuning you go.

Can I use the same battery for both the RX and the ignition? I was thinking of using a single 3200mAh LiFe for both. That is basically to save weight

No, you do not want to use the same battery for the receiver and for your ignition. Why? First, you don't want the ignition to drain your receiver battery while in flight and you lose control of your plane. Second, using the same battery for both could possibly transfer interference from ignition to the radio. You need to keep the radio and ignition systems apart so that don't get interference to your radio.

Is there a minimum rating for either battery? If I cant use one battery, I would rater use two LiFes of lower capacity. For example this one

http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXAAGM

Also, are seperate choke and throttle servos compulsory and if so, can I use standard 3004 or micro servos for them?

Ameyam

My Feedback: (9)

The size of the battery is like anything else. You need to have enough battery for the amount of time you want to fly. Ignition systems are pretty simple and you can get away with a simple Ni-cad or Ni-mh battery. but the Li-Fe will work as well.

standard servos will work fine. But you don't necessarily need a choke servo. If you have access you can just manually choke the engine. Or put an extention on teh choke so you can reach it inside of a cowl or closed in area.
