RE: Need engine suggestions...
how about an Os 160 fx i have it in my extra which is about 15lbs and it does all i put through it. Even a Moki 1.8 or higher will work just fine
good luck |
RE: Need engine suggestions...
Glow sucks.
He already said he didn't want to run glow because of the fuel costs and the mess. He's going gas or electric--but leaning heavily towards gas. And for good reason. Cheaper fuel cost. Thats a big deal for someone who wants to fly a lot. A glow engine in the 1.80 size or 2.00 size will cost you 24oz of fuel every 15 minutes. Thats 5 flights per gallon of glow. Thats $3 per flight if your getting glow juice for $15/gal. I'm not getting my glow fuel that cheap. My 5% Omega is costing me $18/gal. So, thats $3.60 per flight. Kinda hard to fly 5 times a day and 3 or 4 days a week with fuel costing you that much. My pockets just aren't that big. A set of Li-pos for a plane this size will cost you 1/2 the price of the gas engine EVERY YEAR. So, you can run it for 2 seasons on batteries--but then you've spent as much as the cost of the gas engine and now you gotta go out and buy more bateries. Electric is very reliable--I'll admit. The gas engine will outlast the electric or the glow setup. Gas is 10 times more reliable than glow. Gas is 1/4 the price of glow and it lasts twice as long. You get 30 minutes of flying from that same 24oz tank v.s. the glow engine and only 15 minutes. With the availability of gassers today from little 20cc--30cc--35cc--40cc--45cc and all the way up to 300cc engines-----------why would anyone run a glow engine bigger than a .90 today? |
RE: Need engine suggestions...
RVM,
I know the hostetler 27% egde is about the same size as the Great Planes Patty Wagstaff Extra. The wing area has almost the same wing aera. Sinergy is flying a GP Patty Wagstaff Extra with a Brillelli 54 and is hovering it with no trouble. The plane weighs 16.5 lbs and does 3D maneuvers effortlessly. Here is his post. http://www.rcuniverse.com/forum/m_45...tm.htm#4521486 Take a look and see what he thinks. The hostetler edge should fly the same as the GP Patty Wagstaff. The Brillelli 366GT engine is only $575.00 complete and it is customer made for you plane. Brillelli will make the stand-offs in the length you will need. So all you do is install the engine to the firewall cut the opening for the engine and the cowl will fit. No extra shimming needs. The engine is complete with EI, Muffler, smoke tape, and stand-offs. Not extra is need. This engine put out more than 30lbs of thrust with a Xoar 23x8 prop. The engine is only 2oz heavier than a DA 50 with lots more power. |
RE: Need engine suggestions...
Even if the plane weighed 15lbs (240oz.), the wingloading would be 28.8oz/sq. ft. With 4.5lbs of electric equipment, the prototype plane still came in at 12.5lbs - 13lbs. I don't think any of the engines I've considered have an AUW of more than 4.5lbs. That said, lighter is always better! Also, the less weight on the very tip of the nose, the easier the plane will be to balance.
Looking at the BME44 listed on their website shows that the engine alone weighs 2.6lbs, or 41.6oz. That is comparable to the Brillelli 46cc, which, engine only, is right around 38oz (I think). The weight differences between the 40cc engines and the 50cc engines don't seem to be very significant. That's what is making this decision difficult for me. [:@] ORIGINAL: Rcpilet Call Keith at BME and see if he will build you a BME 44. Last time I talked to him--they were in limited supply and being phased out of production. His website claims to have them in stock--but you'd better call him first. He may still have some around and he might custom build one for you if your nice when you talk to him. You need LIGHT. You don't want your wing loading to go through the roof and ruin the way the plane flies. Any 50cc engine is going to be too heavy. That BME 44 is the lightest thing your going to get that will 3D the plane and yank it out of a hover without giving you a wing loading of 35oz. Check into it. I know there are guys here who will disagree with me. It's not about what engine a guy favors. It's not about which is more reliable or not. They are ALL reliable if you just tune them right and treat them to good oil. 95% of problems with gas engines are end-user related. It's not the engine. That BME 44 will be the lighest setup you can get. It will put out the power you need for your intended purpose. Check into it. |

RE: Need engine suggestions...
I know it's a tough call to make. It's really tempting to get a light 50 and use it later on down the road after you smack the Extra.
If you REALLY want the lightest gas setup--then get the BME 44 or that Brielli 46. |
RE: Need engine suggestions...
That's an awesome engine but I think that's way too much power. If this Extra gets anywhere near 16.5lbs I think it will fly like a perfectly scale, metal sheeted warbird at best, no matter what engine I choose. That engine would rip the wings off the Extra! [X(] I'll ask him about it, though he thinks the 46cc (or a similar engine) will be more than enough.
When I decided to get into giant scale (well, small giants anyway hehe) I never thought picking a gas engine would be this challenging. hah!!

Some guy at the field today was talking to me about the weight difference between a DA50 compared to a BME50. Then he said something about 2.9 pounds for the DA50. Big Deal!! What does it weigh with a muffler, prop hub, ignition, battery and mount? Thats how much an engine REALLY weighs. A 2.9 pound Switzelfunk Super Prop Twister 5000 engine won't fly diddly squat without all the rest of the components to mount it and make it run. :eek: |

RE: Need engine suggestions...
Brillelli represents the BEST "value" (meaning quality, performance, reliability, lightweight, and power) out there right now, PERIOD.... I M H O, and somewhat BIASED opinion.
Pass on the ZDZ. Rear carb headaches, needs a canister to be really powerful, and has a six-bolt, pain in the ***** prop hub. Ain't never had a single bolt failure with Brillelli's, BME, Taurus, or Brison.... on a couple ZDZ's - yep - I popped a prop bolt here and there. I'm biased for several reasons.... I have owned, and run the Brillelli 40, 46, and 60. Have also owned Brison 2.4, 3.2, BME 50's, Taurus 52's, Zenoah G 62, ZDZ 40's, 50's, and 60's....and the MVVS 26GT and RCS 180 (both not anywhere NEAR what you need) For the money spent, and the benefit received in service, communication, customization, and reliability - Brillelli gets it. Taurus, and Bill Oberdieck are outstanding also. But more costly. Brison - used to be good, now that it is Kangke-ized I wouldn't buy a new one, period. BME 50's - great performance, but requires additional mount, and tends to shake more than the Taurus 52 or the Brillelli 60. For what you are building - there is no doubt in my mind the Brillelli 46 would be an EXCELLENT all-round choice. If you want INSANE capability for a COUPLE ounces more - get his 60. (Above statements are strictly my opinion, based on MY OWN PERSONAL EXPERIENCE) |
RE: Need engine suggestions...
Hey, thank you for taking the time to give your opinion!
I was wondering about the rear carb on the ZDZ. When you look at the fuselage design of the plane it becomes obvious that modifying the structure to allow for an engine box would be, umm, a pain in the ar$e. How do you like the Brillelli 46 (besides the obvious answer that you like it [:-])? That is on the top of my list right now. Scott says it pulls 22lbs of thrust with a Xoar 22x8 - that's really damned impressive from what I've read, and I have no doubt that it will do exactly that. How much vibration does it have? Do I really need the much-touted 2:1 thrust:weight for 3d and IMAC? I think if I were to put the Brillelli 60 into this plane I would literally rip the wings off, or something. I also think that might be just too much weight in the nose, even if it is just a few ounces. I want to keep the wingloading <26oz.in., and I think with a 3.8ish lbs. Brillelli 46 set up I can manage that. ORIGINAL: aerobob Brillelli represents the BEST "value" (meaning quality, performance, reliability, lightweight, and power) out there right now, PERIOD....

RE: Need engine suggestions...
The Brillelli 60 (366GT, yes?) is almost a pound heavier than the 46cc. As long as I get great vertical performance from the 46 I'll be more than happy. I don't think I could balance the plane correctly with that much weight on the nose without adding lead to the tail anyway.
The Hostetler 300XS builds light because there is hardly any plywood. It's almost all trusswork. I'll probably need an isomount to keep the airframe in good shape. Scott recommended the Du Bro one. I'll check it out and a few others I have in mind. This is definitely not a plane designed to crash! Got any vids of the QQ Yak?

RE: Need engine suggestions...
He said "Evolution".........Let's get back to some good ole American made hp by Brillelli :). I just can't understand why people want to pay so much money for an engine. I guess their thinking old school. If you pay more for it, it must be better $#@$*^)(_()(^*&%^%#.

RE: Need engine suggestions...
Brillellli engines are machined in the US, they use US ignitions, and many parts. However, the jugs and carbs are imported. There ain't no US-made motors, as far as I know. If the cylinder, piston, ring, conrod, come from "somewhere" not US, then it ain't "American Made", at least by Redneck Definition.
The Evolution is basically MVVS. Go here - www.mvvs-nl.com Weights, specs, prices, and info. Pe Reivers is a 100% customer service guy, too. I've bought from him, and used MVVS's. My preference is not rear-intake. |
RE: Need engine suggestions...
aerobob,
I guess that's what I was refering to "Redneck Definition". The Brillelli boys wrench on them to make a better engine so I guess they have been Americanized if that is a word :). I'm not knocking Evolution engines aerobob. I'm just in a good mood becauce I got my glitching problem figured out on my gasser. |

RE: Need engine suggestions...
I have a 2 stroke gas engine that has been modified to a glow. This is a factory made airplane engine. It has an O.S. 8-B carb on it. The engine appears to be new and looks to be approx 38/45CCs. I am trying to ID this engine and the CC is not relavent at this point. How do I post Pics of it for U to try and ID? Tks.

RE: Need engine suggestions...
Why do you dislike rear intake so much? I looked at the carb location on the MVVS 45 and I can make that work without a bulky engine box or anything on the plane I'm building (I'm pretty sure - need some exact dimensions - the only one on Pe Reivers site has the length at about 9.5", which can't be right).
Other than the rear intake, how do the MVVS/Evolution engines compare to Brillelli or others? Right now the Brillelli 46 is my first choice, but I want to explore all options before I decide. The MVVS seems like it might have more oomph than the Brillelli, but I can't tell if it has more oomph only with the canister/pipe set up or if it does with in-cowl exhaust too.
