Evolution 62 EFI

The non-mechanical types among us may not be as certain that "usually" turning the screw to the right, screws it in, and turning it left, screws it out. Also may not quite have the fact down that screwing the screw in leans the mixture and out, richens it. It's EZ to many of us but it boggles the mind of some of us.....I think there's plenty of room in gas modeldom for such an engine.....

Good post. My brother is an example. Our father was a mechanic, and I am a mechanic with lots of tuning and engine experience. My brother could probably rebuild a V/8 engine if he had a good manual, but he can't tune an engine even if his life depended on it. He just can't get the rich/lean concept in his mind nor hear the sometimes subtle differences. He battles terribly with model airplane engines and needs one that is totally "idiot proof". That's why he, and many others like him, have made the electric craze happen. (Well, I hope it is a "craze", and not the beginning of the end of internal combustion engines, at least in my lifetime!)

As long as it runs atleast as well as an electronic ignition equipped 62cc motor should that's what is going to matter. If it runs with the same power as a da50 for example, I'd consider that a letdown. Considering a carbed da50 would have been good enough.

Can't wait to get my hands on this engine. Sick and tired of unreliable performance from DL 50, DLE 55 engines that need tuning very often. I need a reliable engine for 3D operation. This new 62 HH engine will be the ticket. Thanks HH for the R&D

EVO 62 EFI Manual Available Now
Hi Guys,
Just found the Surefire manual is available now from Evo or Horizon. I have attached a copy of the English version for those interested.

It's probably required considering there doesn't seem to be a choke. What gets me is the manual states a falcon prop of 23x9. Maybe I'm wrong but that isn't a whole lot different from 22x10, the optimum prop for a da50 or dle55. I'd expect more from 62cc. But then I'd have to learn how to tune a carburetor argument comes up which is silly.

yes if it doesn't have the power of the 58GX,they just scrap the strongest engine in this class.23-9 Falcon isn't a high loading prop.
guy's get all bent out of shape because they have to cut a hole in the cowl for carb adjustment.now they will have to have a primer bulb to get this one started,but no hole for the carb needles.

Evgeny-arm has some good comments on here really, I think he is misunderstood. But the most important, and I would like to know the answer to as well..
Will the EFI be issued out with the ability to adjust, customize and update FIRMWARE after the purchase?
Like Evgeny-arm points out, the atmosphere varies a lot from place to place, country to country etc, and so the EFI would certainly need adjustments depending on where you are flying, Sea level, humidity and whatever else. And what about updated from the factory after a production run, needing to change the software for whatever reason, do we have ability to update our existing EFI units, or forced to buy a new one... ?
Besides the most important scenario... For the guys that like to TINKER!
If these were released with the ability to plugin a laptop and view the data and adjust, it would put them over the top, in my opinion!
So, can we get an answer to this very important question?

I realized just after posting, that releasing an EFI unit that can be adjusted by the user might not be in their best interest, and I would be willing to bet that the EFI units are NOT adjustable programming.. my thoughts behind that is the fact that if the USER can modify the programming or mapping (whatever the tech word is), then one would be inclined to believe you could swap the EFI from the Evolution motor and put it on just about any other gas motor in its size range, adjust the EFI program map to that motor, and go. I doubt they want that right now.. so I would guess that no, the user can not modify the EFI at all.

I would think the sensors would detect the differences in the various places and automatically correct for them. If the end user were to need to fine tune the programming on the efi to get the engine to run well, why bother with it at all? Why not just stick to needles? I mean, while most can manage to adjust an engine with a needle, I would bet most wouldn't be able to do much with a laptop.

I think a certain segment of users would be very comfortable tweaking a FI map. This really wouldn't be much more complicated than what some people go through programming their radio or what the heli guys go through setting up their FBL units. etc. Only time will show whether adjustments will be necessary. Modelers have never been much for leaving things alone and usually for very good reasons.

Any decent (electronic) fuel injection should adjust for barometric pressure, temperature and load. I would hope this one does.....
Ha! That's funny about HK! I would buy it!

Where is the like button? Oh ya, this isn't facebook. Gas is the way to go. I fly electrics and gas. The electrics only come out on low wind days. I have to say the electrics don't fly much, they just can't handle it. They are more of a kite, because they have to be so light. A gas or nitro engine gives me the ballast needed to fly in windy Texas or windy Illinois. Maybe I should start flying with three battery packs so that my electrics fly more like a real plane. Love that new Evolution.

I have some bad news here regarding the 62GXI. After a gut-wrenching process we have decided not to bring it to market. Detailed testing under various operating conditions showed that it would not live up to our expectations for consistency, reliability, and overall ease of operation. Dealer and consumer preorders will be cancelled. The 62GX engine itself will be released in 2015 as a great-running, traditional carbureted version, so watch for an announcement hopefully around late spring. The plus side is that cancelling this project frees up some resources so we can work on bringing a variety of other engines to market. We have lots of other exciting projects in the works!
