Look at the link on post #19...You send me a G62, you get it back looking like that....The Ebay G62s come with the earlier muffler...

The ZDZ60 RV weighs the same, turns the same prop maybe a little faster, costs $610...Pretty close....Except for the $170 difference and the lifetime warranty on the ignition on the G62....And the 62 has a single bolt prop hub, comes with a muffler...

Thank you for the prompt response......that means it will have the expense of another muffler..still a good deal with the EI..

For what it's worth, don't forget thet the DA has a rear intake and therefore fits better in narrow cowls AND they are working on a .75! what THAT comes out.. then see which engine will be the real STUMP PULLER!

So in a real world comparison, the ZDZ60 swings the same prop alittle more, I think the multibolt hub is safer,,, the ignition should have a lifetime gaurantee,, ?????????????????

Ultimately I don't believe it's really about the differences in the two engines It can't be about quality because too many engine manufacturers have a proven track record of being better by the lack of recalls and longer use histories. As for price versus power Brison had beat the DA quite well, with no service required, at the cost of a couple of ounces. There are others of more obscurity that have done the same. Fox and Taurus to name just two. It can't be a power comparison because the 62 has more, period. It can't be a price comparison because the 62 is less expensive.

I've never seen a prop depart a gasser engine with the exception of one with a multi bolt hub. Never seen a single bolt gasser toss a prop. Seen a couple of multi bolt engines lose the entire front of the engine, though. Took the prop with it so the number of bolts in the hub really didn't matter. Never a single bolt engine. Never had to grind the bolt heads off of a single bolt engine because the bolt metal was too soft and the bolt head stripped under the allen wrench. Done quite a few multi bolt removals. Never seen a single bolt hub shear the prop bolt.

I'm thinking it's all about lemmings, sheep, and cattle. Reminds me of a time when my wife and I went early to a drive in to beat the line to get in. When we got there one booth had about 15 cars waiting for it to open. The second booth had none. We got in the line with none, bucking the herd instinct, and got in first. We all saw the same movie.

Ultimately they're all good engines, but you really need to undrstand value.

Nobody's ever gonna agree on all this stuff, but the RCS website show the rpm of the ZDZ60 RV blue head to be 7200 rpm, no prop brand specified...
Nogyro in a previous post shows 7300 on his G62 and a Mejzlik 22-10 prop...
As to single bolt VS six bolts, you might ask rcbugman...I drilled and tapped the cranks on 4 of his 3W twins to use a single 3/8-24 grade 8 prop bolt after the six bolts on one of his 3Ws sheared and the prop came off and a very expensive plane was lost.....Even if the single bolt should loosen the prop can't come off, the counterclockwise rotation of the engine tends to keep the prop on...
I use 2024 aluminum for the prop hubs on all my conversions, almost impossible to strip when tightened.....I had to use a 3 foot extension on my wrench to strip the threads when I tested 2024 against the more normally used 6061...
You can strip out the allen heads or the threads or hub on the six bolt hubs..I defy anyone to break a 3/8-24 grade 8 prop bolt with anything less than a big sledge hammer

Ralph,

Just wanted to let you know that I put a torque wrench on the prop bolt with your hub and torqued it to 20 ft. lbs. just like I did the stock hub. No problems at all, and I did put one or two drops of oil on the bolt first.............

Thanks for all of the help and info. I have 2 g62's, which run perfectly. Untill I had a radio failure, and went straight in at 80+ mph. All that was wrong with the engine was a bent crank, and a few missing fin's. Ralph fixed it for me, and it runs better than new (Thanks!) :>

G62 EI conversion engine , still have some weigh need to remove , if the iron back plat change to AL. maybe able to save 50g or more

well guys we put a g62 cost here in aust $650 against a da 50 cost $1050 g62 rpm top on a 22 x8 was $6700 rpm a da on a 23 x 8 was 6500 rpm avarage togeather in a straight line da reved out more now this is without electronic ing on g62 or weight reduction and da had more pulling power on uplines . now to convert a g62 to peform like a da you need to spend $350 then mu have a slight weight differance so a da here i australia is better off than g62 so if u have to mod a engine to peforme like a da you are starting 1 step behind try to out peform a da with a 50 cc motor then u got it
i will appoligise to those i offend .

This is a pretty interesting comparison im watching since im about to put an engine in my first gasser. The main question I would be asking is how well will these motors 3d? Obviously theres tons of evidence that the da's will 3d great on planes of appropriate size but will the g-62 be a good 3d motor where its having to create loads of torque or is this going to be more of a speed or sport motor? Ive seen mention of racing in here so i was not sure if this was a torgue motor or a speed motor.

Send my your email addy and I'll send you a video of me 3D'ing my Extra on a stock G62........File is 13.7 meg long.

The G62 will do 3d or any other type of flying just like any other engine.

Try this.....First time I've ever done this so I'm not sure if it will work.

good to know. This g62 is really starting too look more appealing as time goes on.

My Feedback: (5)

So If I get a g62 and send it off what is the cost to get one of these down to 4 pounds? Or even 3 pounds 10 oz? Also what kind of turn around time can I expect to have?

My Feedback: (25)

Thanks for the video. That was some good flying. My questions are: How much pull out is there? It didnt sound like the motor was real high in its rpm range but I never saw a vertical clilmb out of hover. What percent throttle is it requiring to hold hover? Any idea what the planes weight came out too? It said stock g62....So is that not even the lightened version?

Turn around time is about a week and cost is around $150 (I believe) I would go for the 4 pounder not the ultra lite, that way you have a longer prop hub. Ralph does good work and I have 2 of his conversions.
You can also buy them off of e-bay real cheap and that will cover the conversion.
