I have one of the new Cardin Yak 54 planes on order from Hanger 9. They state the flying weight at 16.75 to 18.5 lbs for the plane. I have a G62 that was purchased a few years ago but has never been run. I want the plane to be able to pull from a hover with power left over. Should I buy one of the new motors on the market or just stick with the 62? I have looked into the DL50-xyz50 and a few more. What motor would you guys recommend trying to stay under the 400.00 range?

Thanks,
Guy

I don't see a problem with using the G-62... I would send it over to Ralph C to have it lightened and EI added to it though!

You could also look at adding a pipe to it for that extra kick. Between the 2 you would probably spend the $400 you were thinking about spending on a new engine and end up having more power and be happy with the performance.

You might even want to hold off on the pipe and fly it to see how you like it. At 18.5 it will still pull out with a good prop and have some power in reserve.

Do what Jake mentioned. It will cost about $150 to have Ralph lighten it and add an electronic ignition. As mentioned if it does not have the power you like, pipe it. Remember that the 62 likes to spin up, so prop it for a static rpm of around 7000.

good deal

What is done to the motor to lighten it up? Do you guys recommend a certian pipe or just any pitts style will work?
Thanks for all the info!

If you don't mind the noise a muffler from Abell will give you the most power on a stock set up

dude just keep your g 62 for a scale plane . buy a dl 50 and fly the heck out that plane. instead of spending more money for ane engine you already have you can spend that money and get a whole new enigne you dont have to do nothign to.

That just shows how little you know about engines in general and the G-62 in particular. Which is to say not very much.

At the moment the G-62 will still consistently outperfom just about any engine of smaller displacement. Pipe it and it gets even better. The stock mufflers that come with all the Chinese engines don't do much for noise so you might end up buying another muffler anyway. You can go to Mac's Mufflers in Sacramento, CA and come up with a very high performance pipe for what is not really much money for what you gain. You's spend the same or more to obtain a similar gain in performance percentages with any other engine.

G-62's are not just for scale. They are great performance engines as well but you have to know a little more about engine history and the hobby to recognize that I suppose.

My converted and lightened 62 will turn a menz 23x8 at 7200+, a mezj 22x10 at 7200+ and a top flight pp 22x10 at the same. This is on an abell muffler (loud), soon to have a pipe and I am hoping to gain 600 with no lose of throttle-ability. I should be able to get more according to the $120 dollar pipe manufacturer. So for a $150 dollar conversion (now 4lbs) and a $120 dollar pipe I should have a beast. Not too many engines consistantly pull those numbers, and the engine is just about impossible to destroy. I have been running it at peaked rpm for the last 3 gallons with no lose of compression or power. It is 100 degree's here, I have a big round cowl with little exit area. (didn't feel like baffling this one, I was lazy) They thrive on abuse

So go spend $400 + another $70 on a real muffler vs. spend $150 to lighten a more powerful engine? Makes perfect sense to me.

what all does one lose or get in the conversion? i like those number RTK

Ralph (rcignitions.com) removes the old ignition parts and shaves a little weight off. You end up with an engine that weighs a tad over 4lbs with ignition. It does not have any more performance than the old one, but is lighter. You can use a thinner base gasket to gain a few rpm, but a pipe really wakes up these engine as you know already I remember reading about you piping your Brison. Mine is a 16 year old 62, and they really like to turn in the 7000 range static. Most all of the 62's I have seen on an open exhaust run the same as mine.
I can't wait to try that pipe I ordered.

RTK,

My Brison of 8 years or so threw a rod or something. I have not opened it up to see but i know I can only more the prop about 2-4 o clock and said i will open it up another day so i am on the move to put somethign back under the cowl of the EF Yak. I know the CF Pipe reallly helped me out with the Briison making 23" prop possilbe.

Jackthack, an RC Ignitions converted G-62 will be very perfect of the plane you are putting it on. I have an RC G-62 on my 18lbs. Giant Aeromaster. This thing pull out of stalls , hovers with ease, then will fly stright to the stratosphere. I could not be happier. It is a great setup.
Since you already have the G62 just send it to Ralph and let him work his magic for $150.00. You can have it made with internal electronics in the cup on the back of the motor, or you just have him send it with the sererate electronic module You will get a lighter strong industral EI engine with life time warrenty on the electronics. The money you were going to spend on a DL50 $390.00(American distrbutor), you will need that money for electronics. It will help on those exspensive servos. The new lighter G-62 will make that yak 54 do things it aint sopposed to do I am really pleased with mine and you should be as well.

BTW I have a G-20, G-23, 2 G-38's, 2 G-62's all converted by Ralph Cunningham and I love them all. Just remember when he test runs them he is running them at 6000' above sea level.

By making an engine lighter the performance is effectively increased simply because the weight being pulled by the engine is less. That's like taking 1/2 of a pound out of a 50cc powered 17.5 lb. plane. By reducing the total weight to 17 pounds the plane flys better with the same engine. Adding a pipe takes it even further.

Krayzc,

Likely you have a bearing that gave up. It was common in Brison engines that had suffered a few prop strikes over time. Which was the reason Gary always suggested sending an engine in after a prop strike. I had one let go in one of mine after numerous prop hits in a GP 1/3 Pitts. It was an easy fix. Worst case is the crank sections separated and RC Ignition can fix that. If not I have a pair of 3.2's and I'd let you have a shot at one of them. No prop strikes on either

Tired old Man,

Yeah back when i bought the motor I had a prop explode when i hit the ground and i called Gary or Harvey and they sold me 3 of the bearings that should be replaced after strikes. I still have those same 3 bearings (things that make u go hum). I will set that motor to the side and open it up one day to see if that was the deal. If i get it back up and running I will put it back on a DP Extra that I parked to put the Yak together. I have not seen any of the new mods on the G-62 but all of the old ones with out it that I saw ran like champs everyone that did not have not always brought up the weight issue. I think I would love that power, ops i mean i know i would love that power....

Thanks for all the information. It looks like I will be keeping the 62. Do you guys have any idea how loud (db) the Abell pipe will be? We have restrictions at our field.

This will be my first gas engine set up. If my plane ever gets here! LOL

"You could also look at adding a pipe to it for that extra kick. Between the 2 you would probably spend the $400 you were thinking about spending on a new engine and end up having more power and be happy with the performance".




dude why your talking nonsense. first of all i didnt come in here and insult anybody . second of all your the one that said it was goin to be around four hundred dollars for him to take an engine that he already owns and turn it into a REAL performance engine. you know what, tired old man your rigtht i dont now much about g-62 or a whole lot about gas engines for that matter. i've only been in the hobby two years. i do own a gas engine in my 33% yak . but if somebody tells me that i can take my new engine and spend another four hundred bucks to make it fly my yak the way i want it, i personally wouldnt do it. im not trying tp push chinese engines on you if you want want to . lol what do i care that was my opinion. whatever you decide man, just fly the heck out of it.

Nonsense? The conversion is $150! I said if he really wanted to get some Extra kick out of it he could add a pipe. It's already going to keep up with or beat a DL if he added a pipe it would walk all over a DL with a pipe. Please re-read my post.

**General statement**

IMO Too many people think the DL-50 is the answer to everything. None of the mufflers I have seen so far hold up properly, including the silent beauty or whatever it is from Troy Built. The engines mid range is not all that and there are complaints of things going wrong after getting 30-40 gallons on them. We have a couple at our field and seen several in my travels.

I think its a great engine for your average sport flyer that flies a couple times a month but for someone who burns 2+ gallons a week I don't think it's a smart investment.

**Once again this is my opinion only.**

Jag-the Abell is a stock muffler and is pretty loud. A muffled pipe or cannister would be much quieter. Mac's products make a tuned muffled pipe.

I talked to Ralph today.
The conversion is 150.00.
I'm thinking G62 + 150.00 (EI) + shipping to Arizona and back = At least 500.00 in my total package!
Should I sell the 62 on Ebay (I should get at least 350.00 for it with the pitts pipe and spring start) add 150.00-200.00 and buy another motor to power the plane?
I am so confused about what to do with this plane!

If you get $350.00 for the 62 and the conversion is $150.00 total you will have in the 62 is $500.00 plus shipping, Do it you will be happy with what it will do.

you will have more than that in new motor by the time you buy and pay shipping.

Here is another option from CH ignitions

http://www.ch-ignitions.com/#cat

It uses the original coil and is kind off plug and play for $125.00

The one that Ralph makes has a nice cup mount and all the electronics are in the cup.

Milton

Just a thought but with the RC Exl ignitions it might work out better in the long run to move the ignitions out of the cup.

I just like the looks of Ralphs conversions

Unless he has changed the way he does them, He does not use the RC Exl ignition on the conversions.
