Is there anything out there that even comes close to a norvel .074 for power and weight. I had two and sold them like a idiot[:@] and now I need something for a ACE piper cub I am building. You would thinks someone would have copied there design by now to get a great motor out there for the 1/2A size planes.

That would be why they are fetching like $100 each on the bay. I have at least one of everything EXCEPT the .074

Unfortunately, nothing currently being manufactured. Nobody has copied their design because nobody wants to sell small glow engines anymore. I'd be surprised if anything new under a .10 ever comes out from a large manufacturer.

You could see if Kamdax still has any of their Mig 15 ARFs available. They come with a Norvel .074.

Dont believe everything you read... Thunder Tiger makes an 07 that Tower has in stock for under $50.

I have the TT .07, which has been out for 10 years and it doesn't even come close to a Norvel .074.

Yeah, but the TT .07 runs like an OS..how much power does he need for a cub?...I think that would be a good choice for it myself..I have 3 .074's all three run great, but 2 have way more power than the other one does...he's probably not gonna run full throttle on it anyway even with the TT.07....just my opinion...Rog

At $100 a pop, if your small engine needs are critical enough to need a Norvel .074...they are still priced within reason. If not, pick out a .10 and go have fun.

I think the key to the question is in the first sentance. "Is there anything out there that even comes close to a norvel .074 for power and weight."

To me this means power to weight ratio and no, sadly there is nothing out there that would come close besides the NOS or used Norvel .074s.

What about a Cox .09 RC?

There can be very little difference in actual physical dimensions between .061, .074 and .09 engines.

If you like diesels the AM .09 RC is pretty compact and comes with muffler and carb. Here is an AM 09 compared to a MP-Jet .061.

Mr Cox

Sure, I would love to have a Cox 09 RC...
Are you putting it on the fleebay?

The AM is no longer made and has rather "plastic" throttle. I haven't run my diesel but the glow was a little disappointing in terms of power.
MP Jets are sure good and are similar in price and availability to the Norvel 074.

The only real option, still being made, is the Enya 09, as I see it. They are heavier than the Norvel but this can be improved on slightly by making a lighter muffler.

Seriously, if a model will fly on a TT07 you might as well use an ASP .061 instead and get the same power at about half the weight...

Dan Vincent

Only have one Cox .09 RC so I may hang on to it a little longer.

Those Enya .09 engines are great. They start easy, have good power and are pretty quiet with the Enya muffler.

I don't know why guys have to have the latest and greatest schneurle-ported .049 or .061 wonder to scream it's guts out in a J-3 Cub when a good .09 like the Enya will do the same job with a whole lot less fuss. The starting drill is definitely less intense and a good .09 will seemingly last forever.

Sometimes you need a little nose weight and a heavier .09 could help there too.

I decided an .099 was the proper engine for my 1/2A models way back in 1951 and haven't changed my mind since.

Norvel .074s don't always sell for big $$$. Obviously, if you try buying one on Feebay from thanksgiving to Christmas, or about the time tax refunds get into people's hands, you will pay top dollar. The rest of the year they can be had very inexpensively. I'm up to 5 and have only paid over $100 on one of them. Three of them are used, but that isn't a problem to me.

Next summer when you are flying on a gorgeous day and wishing you had spent the extra money on a Norvel rather than a ThunderTiger or other motor, the extra $20 or $30 premium an .074 brings will seem pretty small. Life is short-too short to not enjoy what you like to do to the fullest. Obviously this can be taken to extremes if, for example, you like to drive exotic supercars for a hobby.... but, if $30 is going to break you then you shouldn't be in the hobby in the first place.

Go get you some Norvel .074 guys.

It takes a little work but I fly on a very very strict budget.

Im not a big fan of the thunder tigers mounting the adj. screw on the carb so I think a os 10 la maybe what ill go with

I just saw a nib cox teedee05 r/c ( carbed model)on ebay , that should have the power of the 074 , depending on the prop sizes you would run. the teedee`s ran at immense rpm`s , I would assume the r/c runs a little bit slower due to it has a muffler and carb , but unless you were going to run a 7" prop the teedee should run comparable wiuldn`t it?
I`m looking for a new powerplant myself , but 049 - 061 for my purposes will do. I was impressed with the norvel 061ame `s power , but I still think my teedee 049 ran stronger based on the way it hauled more butt in my ace alpha than the norvel with the same prop.

What do you guys run these days? I`m about out of fuel and need some help remembering what % the lubricants were

jeffie8696

Jaspur it may have been a case of a poor running Norvel against a good running Cox.

Its a Timex for sure, but maybe a little big for an Ace cub...its only been in the last few years that manf went to remote needle valves,,that shouldnt scare you off,,just careful while tuning...I have a Cox .05 rc td...but,, get what you want and fly it..the cub was one of those planes (and there were many) that I built and threw and crashed...the Cap 21? I think it was I got and it was a real smooth flyer but twice it just fell out of the sky and the second time it was totalled....always wanted to do a corsair, but havent yet...got too many others in the way...gotta finish off the skydrill then I want to scratch out an LS150...Rog

Jeffie , I will not argue the point of it might have been a bad running norvel and a good cox lol, the small engines all too often have their kwerks , have you ever heard of a GOOD running cox queenbee 074? I have had 3 and never heard of a good one. by the third one I decided to put some thought into the design diferences of the teedee and queenbee ( the only good thing on the queenbee was the rear mounted carb in my opinion), thats when I put the queenbee carb on the teedee049

Did someone mention the F4u corsair? I have loved that plane since I was a kid , and always want a flying model of it. I got one of the cheapo cox versions a couple years ago just to hang up and look at. I love the design , but never bought the ace simple series f4u corsair that I wanted for so long because I did not figure I could get the wing right , and she would just fold up. I am still tempted to get a guillows kit just to build one.

My Feedback: (1)

Yeah I did..I'd get either the JKaerotech or the Ace FU (probably will),,the queenbee was only (I know I've written this 10 times) supposed to have the power of the .049,,it was incorporated into the design as an .07 to add the weight of the throttle and muffler, thats why everyone complains about them...Rog

Bipe Flyer

I doubt a stock TeeDee .05 RC is anywhere near a Norvel .074 for power, or the .061 for that matter.

gcb

Although you'd like a NORVEL .074, the TT .074 is enough...see this advertisement that recommends it.

http://www.acehobby.com/ace/ACE4243.htm

It's a 1/2A for goodness sake. The AP .061 is also available.

George

Mr Cox

Since when could one trust a manufacturer for engine recommendations?
ACE would certainly not recommend any other engines than TT for their 1/2a products....

Among the engines still being made I would recommend the AP .061 (and cross your fingers that you get a good one) or an Enya 09RC for applications where a larger prop is suitable.

Both these engines run well on 20% castor, 0-10% Nitro, and are easy to handstart (or a spring starter can be fitted on the AP).

The TT07 is not easy to handstart (and there is no room for a springstarter either) and the power to weight ratio is not good.

Naw Bipe, I just own one ..Dan threw the .09 out there and its not like you can go out and buy either one of them(cox .05/.09)..the Norvel .061 would probably be fine for the Ace Cub but I still think the TT.07 would be fine for it...Rog

Bipe Flyer

The TT07 is not a lot of power for the weight, but it'll spin a larger prop than an .061 glow and is pretty easy to run. It'd fly the ACE Cub fine.
My 1/2A Stik and Mini Bipe Stik. The Mini Bipe Stik now has a Norvel .074 and a lot better performance.
