Yall, im stuck. Im buying a 74 inch Great Planes Extra 300s, and im going gas not glow. Well im stuck between two engines, the DLE-30cc and the CRRC-40cc. A buddy off mine has the exact same plane with a Brisson 40cc and its bad to the bone. Im going to order it from Vally View Rc, the DLE-30 is $319.95 with free shipping and the CRRC-40 is $279.95 with a shipping cost off $12.90. One problem is that the DLE-30 is out off stock. But my main concern is CRRC, how reliable is this engine? I dont know anything about it. What engine would yall go with? Would you wait for them to get the 30's in stock are would you go with the CRRC?

dont know about the crrc40 cant seem to get mine running at all michael

Did you buy it new? Have you ever started it at all? Whats the deal?

Hi Moki 1.8, I have had three Brison 2.4's and three Brison 3.2's at one time or another and they all ran like a top. And I mean they were perfect from the time I opened the box. Yes things have worn out like bearings, rings and carbs but I always got superb service from the guys in Dallas and now BJ's Engine service. I know it's difficult to spend another $200 to $300 dollars on an engine when you can get one so much cheaper. Check on those Chinese engines. They come and go on a regular basis. Some are good and some are bad according to the posts and the experiences I have seen at my field. If you want to have a trouble free engine, I recommend the Brison. Dan.

Yea I hear you on that. My buddy has the Brisson and it seems to be a awesome engine. There just kinda costly though. I'd love to get one but im already tight on the funds.

Put a DL 55 on it. You could always use the extra power.

I just checked on the Brison, its $449.95 and $98.00 for the pitts muffler. Man thats a lil steep.

get the DL30, there is 2 reasons why, one DL is amazing brand, second...Jody from View Valley is one of the best person out there for costumer service so you will be safe after you get it

Yea I think im going to lean towards the DL-30. Although id really like to have that 2.4 Brison though. My DL-50 that I had was a awesome engine, im sure the lil 30 is going to be just fine. I was thinking of that CRRC 40 because it is more cc's, I like more. If I could I would put a DA-150 on that plane, lol. Just kidding. Yea I might just have to go with the 30.

yes I got it to run for 10 sec and it just pops now and again the spark looks weak at best and also looks like its not firing all the time I also tried the clamp on the cap I think its a bad ingition unit I also pm jody to see if he can help and yes i bought it new as a kit on e-bay michael

Go with the DLE 30. I think you will have a more balanced airframe and lots of power to boot.

I have the crrc 40cc. Its a decent engine. It has a problem with starting backwards frequently. Other than that, its ok. Dont know about using it in a 3d type of plane. On the other hand, if its just general aerobatics and playing around it would work fine.

I sent you a PM. Dan.

The 30 is not enough engine for that plane. Buy it and you'll end up buying another making it twice as expensive. get the CRRC and you have a 50-50 chance of getting an engine reliable enough to do the job. So you may buy that one twice as well. You don't save a dime either way, and in fact spend more than you would had you got the right sized engine of good quality the first time. A high quality engine will last you 20 years if you take care of it. A low quality engine may not get off the runway a first time.

You'll need at least a 2.4, or 40-42cc ngine to fly the plane. There are some good companies out there that sell great engines. Not cheap because they aren't made cheap. Do yourself a favor and get a good engine the first time, and do us a favor in the process by saving us all the time and effort responding to your later posts about the other engines that didn't run well or didn't have enough power.

This is what I would do:

That or a ZDZ 40

The one in the link is still only 30cc and will not effectively meet the need. Fox and First Place are two other sources. Taurus just might have a 2.4 that has not been sold.

Hey can I get some help I have a ZDZ 40 Rv i slapped in a Rc Guys Super decathlon . I had the engine running for about a half hour now she wont prime or even suck any fule at all I took apart the fuel lines no prob there i took apart the carb no junk in it. If i push ont he diaphram i can blow into the vent tube and force gas into the carb.

Please any help would be greatly welcomed
yes the engine is brand new

94 octane and honda hp2 32:1 was used engine purred when it ran

Moki 1.8, I used to have that plane (Gene Soucy Extra) and it flew quite well on an OS 1.60. I know for a fact that any of the props used on a 50cc engine will be WAY too big unless you get taller landing gear for it (a 20" prop will work fine, but will require 3-point landings).

I was going to comment on the CRRC engines based on their past history, but the newer ones seem to be pretty solid. I have a good friend who just put together a plane with the kit-built 40cc engine and it is a very solid engine, runs great, etc. I think that is the one VVRC is selling for $279, but Jody assembles it and tests it before shipping. (He is an ASE-certified mechanic with over 30 years of experience, so he knows what he is doing). He will guarantee the engine will run.

That engine with a 20x8 or 18x10 prop would be just about perfect for the Soucy Extra. Figure the power will be somewhere in between a Moki 1.8 and a Moki 2.10, for a similar overall weight (gas planes carry less fuel than nitro planes, so overall weight would be similar).

This plane should fly very well. If you want to fly around, do lots of rolls/loops/spins, etc, it will be perfect. It rolls very well. I LOVED the color scheme too, it is highly visible and looks very sharp in the air. I had issues keeping my OS 1.60 running so most of my flights landed in deadsticks so I can tell you it is very well behaved on landing approach, but it seems to land faster than larger 50cc planes.

Note that if you want to do 3D type maneuvers you will have a tough time. The plane will hover, torque roll, harrier, etc,. but you have to be very quick on the sticks to stay ahead of it. It is harder to fly and a larger 50cc plane, and significantly harder than a 100cc or 150cc plane (which feel like they are on autopilot by comparison).

Greg,

You might want to post this info in a new thread so more people will see it. You will be more likely to get some assistance if you do that (otherwise the only people who see it are those who read this thread).

You are right on the money with oil and gas, so no problems there. If you get fuel into the carb, will the engine run? Does the engine make a "clicking" sound in the crankcase when you turn over the prop? Do you have a good spark at the plug (pull the plug, hook it up to the ignition, turn over the engine, look/listen for a spark - don't get shocked!)?

Is this a brand-new engine, or is it old (more than ~7 years old) but never run? There was a problem with the Bing carb ~7 years ago but all the newer engines have no problems (now have Walbro carbs).

If the engine will pop and run when gas is forced into the carb, you might need to replace the carb gaskets/flapper valve/diaphragm set (Walbro carb rebuild kit is ~$7 at a lawn mower shop).

Clicking in the crankcase is a loose drum rotor plate. Just tighten the holding screw a bit and tighten the securing screw and you are good to go.

If you can't get a spark at all, the ignition may be shot.

If this is a brand new engine purchased in the last few months, Troybuilt Models should give you warranty support for it. I don't know whether they will honor warranties from RC Showcase, but it is worth asking!

Good luck!

Great looking plane by the way. I love the look of the Decathlon.

One more thing, the ZDZ 40 with the Walbro WT-76 carb or WT-201 has an internal pulse port passage (tiny hole) between the crankcase and the carb. Sometimes the carb gasket can slip a bit and cover this hole. Check the alignment of the gasket to be sure it doesn't cover the pulse passage, as that will guarantee the engine won't pump fuel!

DLE-30

Of the two engines you asked about the 40cc would be the better choice for the airframe mentioned. The 30 will fly it but it wouldn't be impressive, BTerry's advice is spot on as is T.O.M.'s. But, if you want or need to go with the less expensive engines, they do work very well and if purchased from a reputable distributor any needed support will be there whenever it's needed. If you go with the CRRC 40 I would recommend upgrading to the Rcxel ignition.

I should have stated that while the plane flew "well" on an OS 1.60, it didnt' have much excess thrust and had a hard getting out of a hover. From a cruising speed straight and level it would climb vertically maybe 300' or so before running out of steam.

My OS 1.60 swing an APC 18x6w (about the same load as a Xoar 20x8) at right around 8600 rpm tuned down from the ~9000 rpm peak. No 30cc gas engine on the planet can touch an OS 1.60 in terms of power. More CC's are definitely required because as they say, there is no substitute for cubic inches (you can always throttle back).

What does that plane weigh? The Extreme Flight 74" Yak is ballistic on the 1.60 and flys like a scalded dog with my Brillelli 46
