There ya go.... Another village heard from......opinions do indeed vary. Personally, I think the Evo 45 CC is cuter.... I like Blue.....The guys that have them seem to like them a lot....

I don't know if it would solve ALL my problems, like that fella's DA50 does for him.....but it would probably help my self-esteem a little bit....

I'm feeling better already!

i wasn't going to jump in here but the 45 was brought up.i got a MVVS 45 that had need of new crank bearings after 4-5 gals. of fuel.the bearings were BONE DRY there was no way to get any lubrication to them.but the new crankshaft has a lubercation port down the center of shaft that exits in between the bearings now.what i am trying to say is most newly design engines go through a (get the bugs out) early on.
to be fair i also had one of the first da 50's that went back for updates.

Yep, sounds reasonable. I've gotta say, if you knew what RC was like 25 or 30 years ago, you'd marvel now at all these cool things. We had these old Fox glow motors back then which were THE motors to have, and even the very best one, which was called something like the Eagle, it used a TON of fuel, it blew slime everywhere, it was temperamental, you had to kind of FEEL your way through it and adapt it to your region (We're in Maine, nothing liked it here!) using bits of fuel line on the needles because they leaked air in the cold weather. Now, when things aren't perfect out of the box, you get guys who want to start an uprising about it. Man, we used to DREAM about having access to technologies like this. When something is new now and an issue arises, the manufacturers actually DO something about within a fairly short period. We'd have been SO pleased to have had access to any of these present engines. A small Quadra back then had BUSHINGS and weighed a LOT. The premier gasser you could get was the Zenoah G-38s through G-62s, which were STILL heavy but at least had actual bearings, a BIG selling feature then.
Now, I'm the first to admit that the DA50 is an awesome powerplant, but at this point it's all in degrees. Being a motorhead myself (which means I can take anything in the WORLD and make it run right if I set my mind to it) with WAY too many years of RC engines under my belt, I decided on the EVO 45CC gasser with the electronic ignition. I was giving the DL50 some serious thought, but figured that since the EVO 45CC gasser is a Horizon product that the support would be there, like for the JRs and the Spektrums. You don't have to LIKE the hobby giant companies to recognize advantages they offer you. So anyway, I struck a balance there between overkill and high/low prices, I think I'm going to be real happy. A small side-note is that I don't do hard-core 3D flying, I dabble in it but it's really not the kind of flying that I love to do. This plane should be WAY more plane with this setup than I'd ever require! If I were a diehard balls-to-the-wall kind of flyer that just lives, eats and breathes 3D, I might go whole-hog on the DA50, but even then I think this setup would do a pretty good job, lots of other guys are quite happy with it and using it for that.

Besides, I like the pretty Blue on the engine. ( Man, I love trolling for flames!) Even the stand-offs are Blue!

The DA 50's are bad about girgling in the mid range , Look at the post and you will see that is probably the most common problem.

In RC, mid-range has always been the most difficult place for both glows and gassers. And it could be the engine, it could be the carb, it could be the modeler not knowing how to set a gasser just right. I've gathered from the posts that the DA50s require being run a little richer during break-in, and you're not going to be able to avoid gurgle during a rich phase of break-in. Not just with the DAs either. Gas or glow, you can break and engne in fast or slow, and slow is always better, and in most cases richer is better. In the end, might as well say that PATIENCE is better, because that is what is required to take the time and the trouble to make sure your engine lives a long life.

Jim

Yep Jim your right....Most dont wait until the engine is broken in....just need to slowly lean it out when it allows you to.....My EVO45 had had girgle but it never dead sticked and I just leaned it out after breakin...now everyone at the field asks about it....Great Engine.
About the baerings...havnt checked them yet...

Starting to feel like a pinball now. I was told that the H-9 Extra 260 I ordered would be shipped around the first of the month, so i called Horizon today to verify that.. They told me that model is going to be on back order until at LEAST the middle of February. I decided that I'd better make some choices or I'll be starting my winter build project in May. So I cancelled it for now, and my LHS guy is holding my credit for it, there's little doubt that I'll use it up before spring! I found the Wild Hare site and I've been looking at his 3mmTOC 53CC gasser and reading up on it. I think I might go with one of his combos, perhaps the Edge 540 30% and that engine. I'm researching it but the user reviews look very good so far. The price is better too. A tad heavier, but the engine has something like 8CCs more displacement than the EVO 45 I was eyeing, so it's about right for its size. Excellent dealer support too. That counts for a lot in my book, when you can have that and a lower price. So, I'm off and starting all over again on this!

Jim

Good luck on that....seen the add for the 53ccTOC but havnt herd anything on it....I am a Extreme Flight Fan..lol There planes are very well built....bought the 50cc Yak from Nitromodels too and it isnt all that bad....for 300 bucks.

Actually, engine-wise I'm not too worried, I can take anything and make it run beautifully. It's got double three-ball dearings in it so it should be pretty sweet. Walbro carb, and so forth. I'm trying to make sure I get a good aircraft, though, and to be honest, the H-9 260 27% was getting about 50/50 good and bad. All of them said it flew good but left something to be desired in the construction. If it got rave reviews about every aspect I'd maybe wait.

Jim

Hanger9 has good support...BUT they need it...not a fan of their planes...3D ones anyways....they just take from areas that needs it to save weight or money? whatever the reason, its bad.....owned 4 of theirs, but not the one you mentioned.....just wont do-it again...Michael OH, The EVO I have came from Chiefs and it has the older ignition which will run on 4.8 volts and 6...the new version you can only run on 6 volts and has alot of electronics that I dont need.....
I know some of us is going of topic but some people need these answers...enjoy what ever you get...

I know this is technically the Evolution vs DA-50 thread. It's also interesting to me (and I'm sure for other guys who are looking for 50cc powerplants) to see what else weighs in on the same class.
What impressed me (enough to buy a plane, hardware pkg & Toc 53CC engine combo from him) was that Tom at Wild Hare pays RC Universe for his thread and support thread space, and yet he was spending a fair amount of time trying to help another guy with an engine he didn't even buy from Tom. In the end, Tom had to cut him loose because it became obvious the guy needed to go to the actual Mfr with the problem, but I was very impressed that with everything he has to do that he took that time to help the guy. Manufacturing that much equipment (Okay, IMPORTING some of it) and distributing it takes time either way. The guys in the thread talk about speedy support on the 50CC engines and quick turnaround time.

Here are the engine specs:
3MM TOC-53
Specifications:
Bore/Stroke: 44mm/35mm
Displacement: 53cc
Weight (bare engine): 58 oz
Props:22x8 - 24x8
RPM baseline: 22x8 @ 6700 - 6800
Bearings: 3 ball & 2 needle
Hope this photo comes up okay. This is the color version I ordered. After the H-9 I was originally going to get, I feel like I'm the equivalent of Harrison Ford in American Grafitti, showing up in his black 57 Chevy Bad boy car!

Now, in some of the blurbs about this engine, Wild Hare says it's equivalent and some of the results show it is stronger than a DA50. No matter what the "actual" results are, it sounds like I'm going to be plenty satisfied with the power output from this3mm TOC 53cc gasser. Now that I've made a somewhat unexpected switch from the EVO 45cc to the WildHare 53cc, I wonder how the EVO and the Wild hare would compare? Actually, I wonder how it would compare against both the 58 AND the 45....
