Status: offline 		smilam - I have an older CG Sukhoi 26m - 73" - with a DLE 30. I had no issues at all mounting the engine - it fit easily and the cowl \ spinnerplate distances is about 3/16". I love this engine - and it's perfect for this plane. LOTS of power - both speed and vertical. And that's using an APC 18x10 - I'm about to change to Xoar props, which, from everything I've read, are more efficient. btw - also very easy to start.

For your 232, I'd go with a DLE 20 - (I have one in my 70" GP Revolver). Also an excellent engine with plenty of power for it's size. I'm using an APC 16x8 now on that.

Status: offline 		Thanks for the replys. Chief does have a good deal but I think I will go with the DLE 20 for the Cap for now like Microdon2 suggested. I need to replace the on board glow and the flight batteries this winter plus the muffler is coming apart at the seams so it needs to be welded back together again? I will hold off doing anything on the Sukhoi untill I get the Cap going and checked out.
I see that Tower Hobbies have the DLE 20 in stock but I would rather buy one from Valley View but they are out of stock. I prefer to support the smaller guy if reasonable so I guess I will give them a couple of weeks to see if they get some in. Kind of like supporting the LHS so the bigger guys have a little competition and the LHS is there when I just can't wait.

It did the DLE "high idle" thing for 30 secs and then came down to a nice slow idle while on the ground, but in the air it took much longer to drop - or never dropped. Some of my landings changed to go-arounds cause the idle just didn't drop in time. Do I need to richen the low end due to the cold air? (could have tried that but I had to get going to work!)

Hi AND low should be adjusted richer as the air cools generally. The colder air is denser, packs more oxygen, thus requiring more fuel to maintain optimum fuel/air mix. Your reward for dinking around with that will be noticeably more power!

Status: offline 		Tried richening H and L this morning (32 F) and the engine did come down to low idle a little quicker, but the engine then burbled very noticably while running. And the low idle died after 30 secs - even with a few up-clicks of the throttle - seemed be TOO rich. I closed both a bit but then the idle stayed high longer. Seems like I'm stuck. Any suggestions?

This is the only thing I don't like about these DLE's. I believe TOM or Jody said you can solve this if you replace the EI with the EI from the DLE 55, which I believe is a #4, then just have to use premium gas. Does this sound accurate? (though I'd rather not spend $80 if I don't have to...)

This is somewhat turned around. The DLE ignition #4 was in the DLE 20 and is the one with the odd ball advance curve. Some people do not like this one.

Correct - The DLE 55 ignition has the standard RCEXL advance curve and is generally more desirable.

Is the maine reason for getting the Bowman ring is to allow a quicker break in?

I doubt it will prove the power unless there is something wrong with the ring already in the engine.

Ask yourself,

What happens to the ring as the engine heats up? I wonder if the maine reason is the same as the rhode island or florida reason.

Quicker break in? Does that mean quicker wear out?

I have heard guys claim 3-400 more rpm with a Bowman ring on other engines. Just wondering if any here have. We have a DA 120 that the ring gap is to wide like .015 way to much.

I do seem improvements already in the the 30 that can be done for a bit more power.

Status: offline 		For now i will put it my H9 Miss America. It will be about 8.5-9lbs I plan to run a 16x14-17x13 APC on it. it will not be all that fast maybe 110-120. I like to tinker with engines and learning on how to make Glow two strokes run well. These gas will take a while to get some good power out of them. limited on carb and reed changes. as far as i know there isnt much out there. This is a new area but will be fun. The ring on this engine is huge. can be made thinner for sure and still run just as well. I dont care if the ring doesnt last as long as the stock one. If i can get two seasons on one ring yet making more power then all good to me. I will get to measuring timing tonight. I know I maybe late to the gas game but will catch up.

Are there any programable ignitions out there? If down the road i want to change the timing curve while keeping the stock timing at idle but retard the timing at rpm like say 23-27 degrees. I did a mod on my Yamaha raptor engine where i have three spark plugs in one cylinder. This allowed me to run less advance because of the three flame fronts burning the fuel mix faster. This allows less negative torque which = more power. I netted around 7.1-7.8 Hp doping this on a 760cc engine. anyway this is down the road some.

airraptor - you sure don't SOUND "new to gas"! Good to hear you're already experimenting. I love that Miss America paint scheme. But, size-wise, it looks to me that a DLE 20 would be a good - maybe even tight - fit, given the narrow cowl. Not surprised that you're pushing it to the next level. Looking forward to seeing a video of this future beast.


(120 is "not that fast"???)

Status: online 		Over the years I have used nothing but Bowman rings for my replacment rings. I have several with many years of use and they still perform like new. So to answer do they wear out faster I say no they don't, however they will take the shape of the cylinder quicker than the harder/ brittle chinese rings do and not have the need for a 5 gallon plus breakin period to achive a full seal.
More power, any time that a ring is fully sealed in the cylinder thats all a person can expect for power, but I have torn down several engine's with 2-3 gallons of gas ran thru them to find the original ring still was not fully worn in and a larger than needed ring gap.
I think it was Capn't John that was one of the first to put a bowman ring in the DLE-30 and had great results from it, maybe he can chime in here.

Status: online 		The Frank Bowman piston rings too me is the way to go. They are made with great care of with the right material and hardness to give very good seal right away. Every engine I have used Franks rings in had better compression right away. A good seal is important. It will prevent the intense heat from combustion to travel past the ring turning the piston a brown color.  Cyberwolf posted it real clear also...a small end gap and the shape of the ring to conform to the cyl is what is needed.   I replaced a ring in a Webra 1.20 that would not hand start from new. With the Boman ring it started by hand real easy.  Ask Webra owners how the stock rings work for hand starting!     Best Regards,   Capt,n

Status: offline 		Have you ever seen a gapless ring for a two strokle gasser ?
Gapless rings are for four stroke engines with no transfer ports..
How would a gapless ring work in a two stroke ?
My guess is there is no such thing, unless it's by definition not really gapless, just less than normal gap of about .0045 for every inch of diameter...
Large Large SuperTigre engines had rings with almost no gap several years ago, did not work well..The rings expanded when hot and stuck...
Total Seal gapless rings were made in Phoenix, don't know if thery're still aroung...

If you want to program a ignition curve...there is a ignition that has that feature.  Send a PM  to mpascual.  He can give you more details.   Capt,n

     http://www.precisionrings.com/rings.html?gclid=CKulscr22a0CFYtX7AodqAj-mAPrimary Sealing:In the case of an expanding ring, primary sealing is established at the ring outside diameter (OD) surface and the cylinder bore. For contracting rings, the primary sealing is formed by the inside diameter (ID) making contact with the shaft/rod. This contact is maintained by the inherent tension built into the ring until pressure differential is sustained across the ring. Pressure differential keeps the ring "seated", forming an effective seal.Secondary Sealing:This is established at the ring side face in contact with the groove wall. The desired clearance between the ring and its groove forms a flow channel that carries fluid to the back of the ring to establish pressure differential. Once pressure differential is attained, the unbalanced reacting forces at the ring sides cause the ring to form an effective seal. Both primary and secondary sealing produce the desired sealing action for the application. The same factors that contribute to seat the piston ring also cause drag forces. Axial Drag Forces are a result of the high pressure fluid acting on the I.D. surface of the ring and the coefficient of friction between mating surfaces. In addition to this force, one must consider the drag forces due to the ring's inherent tension. On very high pressure applications, these drag forces become almost negligible by comparison. For low pressure applications, rings must be carefully designed with drag forces in consideration. Another type of drag force is caused by friction between the ring side face and the groove's side surface. If this Side Drag Force is too large, the ring will not achieve primary sealing contact. Again, for low pressure applications, this drag force must be carefully balanced

Status: offline 		The timing curve of the old original syncro spark ignition was just right..4 BTDC fpr starting, linear advance to 28 or 30 at 4000 rpm... .It was designed by Ed Vollmer and sold by C&H....No one has so far been able to clone it..
RC EXL got close, then screwed it up when DLE wanted it changed...
There is no real need for an advance curve on our toy gassers anyway..28 total works just fine except for starting...And then no retard is needed if you use an electric starter.I bet 99.9% of all model airplane pilots couldn't tell the difference between different timing "curves"

Status: offline 		Looking over the DLE last night. the ring is very thick. A new thinner ring would help in the power part but would require a new piston.
Yes the gap less rings would require special setup to run in a two stroke. I remember reading somewhere about someone making a special ring pack to be gap less just cant find it again. This was early on when the DLE came out with the V1 30. On this size of engine I now dont think it would be that much of an improvement. The thinner ring correctly gapped would be better. I was looking for a programable ignition for running three spark plugs in the the engine. there is room in the cmabe for them but untill i am racing on this engine it isnt worth the trouble right now. for the extra weight of the two extra ignition units i could just instal the 55. I will look at a larger carb of clean up the stock one. work on the porting some. the exhaust is very narrow. I didnt measure the ports yet though. I will order some bowman rings today.
