Kudos to Antique (Ralph Cunningham)
Mr Cunningham deserves real Kudos for the service that he provides to his customers. I had one of his G62 Lite engines carried over to the UK by my brother about three years ago. The engine must have been moving about in the luggage because the ignition sensor leads had broken off. I only got around to sending an IM to Ralph recently and he promptly offered to send me a new sensor free of charge. I emailed back saying that I'd like to purchase 2-3 sensors just in case I needed any in the future for this or his other masterpiece that I own - a G26 lite. A few days leter I received three sensors via airmail - still no charge, even for the postage. I think this deserves a public thank you and recognition for outstanding service. Ralph - I feel really guilty about you paying for three sensors and airmail postage when the problem had nothing whatsoever to do with your workmanship, which I have to say is absolutely first class. Your engines are almost too beautiful to put to use! So I will gladly make a payment if you care to send me an IM or email with the amount. Thaks again. MSS.

There's one on Youtube with a G26. http://www.youtube.com/watch?v=vb1_b_RFfK0 If you examine the construction of a Hannibal, its very light so would have said that a G26 would be better.

Engine Choice for the Novice
Right now there are a quite a few interesting threads ongoing about various engines and manufacturers. But these don't help a newcomer decide what to buy - only what they really shouldn't touch. So here is an attempt to present the good, dependable options for a newcomer to the world of petrol (sorry, gas) engines. [b][u]Less than 20cc[/u][/b] Don't bother. [u][b]20 to 25cc[/b][/u] Good Prospect: DLE20 Proven Dependable: Zenoah G20; FPE20; Convesion engines by some of the experts e.g. Echo 21cc conversion Premium: Zenoah G20 on a Toni-Clark mini-pipe (added 27/06). [b][u]26 to 30cc[/u][/b] Good Prospect: DLE30 Proven Dependable: Zenoah G26; MVVS/Evolution 26 Premium: Ralph Cunningham Zenoah G26 Lite; G26 on a Toni-Clark mini pipe; MVVS/Evolution 26 on an MVVS tuned pipe; Syssa 30; 3W 28 (added 27/06) [u][b]31 to 50cc[/b][/u] Good Prospect: ? Proven Dependable: Zenoah G38, G45; MVVS/Evolution 35, 40, 50 Premium: Ralph Cunnigham worked G38, G45; MVVS/Evolution 35/40/50 on a tuned pipe; DA50; BME 50 Classic [b][u]51 to 60cc[/u][/b] Good Prospect: DLE 55 Proven Dependable: MVVS 58; Zenoah G62; ZDZ; FPE Premium: Ralph Cunnigham G62 Lite; BME 58; DA60 [u][b]>60cc[/b][/u] Will not need to ask! Feel free to copy this list and add your candidates for each category. But let's keep this sensible and real, so if someone is happy with their PQR50 with anodised prop bolt then fine, enjoy, but it doesn't belong in this list for newcomers where the probability of use over the first year without any issues should be better than 99.5%.

RE: Engine Choice for the Novice
I agree with everything that the last post says about engine size. A 20 - 25cc is ideal for starting out in gas for many reasons - ease of handling, ability to use standard size but good quality servos, relatively inexpensice props and so on. But, it then does exactly what the original post was created to avoid which is to say ...and the anwser is engine XXX.... The answer is a number of candidate engines, three in the above list at 20cc, at different price points and [u]proven[/u] quality/longevity levels. But they are all good options which is why they are on the list. To give you an example where a Zenoah 20 would be a much better option, in most of Europe and parts of the US noise is a major consideration. In the UK none of the DLE engines as delivered can be flown at club sites that comply with the BMFA recommendations on noise. The G20 can because it comes with a very effective silencer as standard. To get the DLE20 down to the same noise level as a G20 would push its weight up roughly to the same level as the G20 and the cost above that of the G20. So for many the G20 may actually be a better option given these differences and its heritage of quality/longevity. As with most things in life, its a balancing act at different price points whilst working within what I would call reasonable boundaries of risk of failure/disappointment/loss due to the inherent quality of the product.

RE: New statement from JC ENGINE power co.,ltd
As an example of a good product and factory support for the distributor, the European distributor for Zenoah engines has been in that role for over 25 years. He provides a 5-year warranty on all Zenoahs and is able to honour that without question. That says a lot about the quality of the product and support from the manufacturer. This should be the bechmark.

RE: Engine Choice for the Novice
[quote]ORIGINAL: Tired Old Man As a newbie one should be concerned with only two things. Ease of use and reliability. Any engine that qualifies in those two areas has the power necessary to do the job when the engine is sized appropriately. [/quote] Agreed. That's exactly where I was coming from when I decided to compile the above list. The interesting thing is that the cost of any of the engines listed above over say one year of use/enjoyment is most likely going to be lower than the alternatives that are initially cheaper to purchase. And over the lifetime of the engine, anyone buying one of the proven or premium engines is going to save a lot of money and enjoy the hobby considerably more.

RE: New statement from JC ENGINE power co.,ltd
Subscribed - will be interesting to see what happens in the next 12 months. I think there is room for one or possibly two more Chinese engine manufacturers to become profitable competitors to DLE, selling a reasonable and consistent quality product at the same price levels as DLE. This is a real business opportunity that could be won by DLA or JC or some other. Whoever it is will have to work at it and take the long term view rather than just quick profit. JC will have to work twice as hard if they wish to have a future inthis space because of their track record. So there is a real opportunity at the moment for a maufacturer to step in with a view to delivering DLE comparable quality, support and prices. The rest of the manufacturers will probably have to remain selling sub-standard $150 engines to unsuspecting first time buyers but not for much profit and will come and go. My guess is that there probably isn't much profit in making and selling these sub-$150 engines and that the incremental cost to consistently produce a reasonable quality engine would not be that high. As I said, it will be interesting to see if any of the current sub-standard manufacturers have the foresight and business acument to realize what they have to do for long term survival.

RE: Zenoah G23L - Any Experience?
Hi mikenlapaz, Good call. I checked on the G23L and that rotates in the right direction. But, I just picked up two engines from the local garden machinery shop that services my ride-on and other machines. They know about my love of engines and put aside anything that may be interest to me. One of the engines is a Zenoah 22 on a hendge trimmer that had been serviced but the customer never collected. The other is a Kawasaki TF 22 again from a hedge trimmer. Both really nice engines. But would you believe that they both rotate clockwise. I've removed the casing from the TF22 so far. A really nice engine and lightweight engine. The magneto is mounted in the casing so would have to use EI. But with the excess metal trimmed off, it only weigh's 35 Oz without a muffler or igninition components. I think I will experiment using in a pusher configuration rotating clockwise for an airboat.

RE: MLD-35 Gasoline Engine
George 32, Don't stop there, your list and praise isn't complete. You missed other great virtues of some engines. They start off at below 30cc and soon end up being close to 40cc due to interesting design features or manufacturing processes - I guess these would be called side benefits. Some also lose weght as time progresses by dropping cranks, melting bearing cases, losing mufflers and so on. Throw away the ignition when it stops working after about 3 weeks and more weight saved! By comparison the heavyweight Zenoah's hold onto their excessive weight for years. In Europe they come with a 5-year warrantly that no one ever seems to need. But they are definitely no good - RCG is obviously the way to go. As for MVVS, who wants their quality when you can have infinitely variable (read uncontrolled) running characterstics from some of your listed engines? It must be like having a different engine for every flight. [:)] Of course I'm not serious (well, maybe a little) but that last post almost ruined a really interesting thread for us nowadays lonely Zenoah men. [:'(] FYI - About 18 montgs ago I compared a Zenoah G20 with an Aerovate (RCGF) 20 side by side after reading all the praise on the latter. By the time I had fitted an effective silencer to the RCGF to get the noise down to the same level as the standard G20, it was slightly heavier and had cost more. The G20 also produced higher thrust. Balance and perspective. [;)] Ok - back to the MLD and hopefully without denigrating engines of undeniable quality and track record. MSS.

Question for the Walbro/Zenoah Experts
I have used the WT-338 carb from my Zenoah 38 for a bit of experimentation on another engine and need to purchase a new one for the Zenoah. I could purchase another WT-338. But there is also the WT805 as used on the MLD35 and there are some WT 542's for sale on the well known auction site at relatively low prices. These are all 13.5mm venturi twin needle carbs. So my dilemma is about which of these to buy as apart from general dimensions, throat and venturi size etc. I don't know enough about Walbro carbs to be able to tell from the part numbers whether they will have similar running characteristics due to jet sizes, metering spring and so on.

RE: DLE 20 compared to Zenoah G20ei
ScottMcM, How does your DLE20 compare to the G20ei for noise? I did some side by side comparison between the RCGF20 (Aerovate 20) and G20 couple of years back and out of the box, the G20ei was far quieter. Due to it coming with a proper silencer as standard rather than just an exhaust diverter. To get the RCGF down to the same subjective noise level required their wrap-around muffler, which pushed up the cost to the same level as the zenoah and the weight one Oz higher. That exercise made me appreciate my G20 even more - a cracking little engine that oozes quality. In the Uk, flying sites are lost due to noise complaints so its a key factor in choosing an engine. Thanks. MSS.

MVVS 26cc Pipe on Zenoah/Brillelli?
I am thinking of getting an MVVS 26 pipe (#3266) to try out on a Raplh Cunningham converted Zenoah 26 and a Brillelli 25GT. This is purely to educate myself on the tuning and use of pipes. Does anyone have experience of either of these engines on a pipe? My driver is to quieten the engines and to achieve the "tuned pipe sound" rather than any significant power gains. Any power gain would just be a welcome bonus. I will probably try the pipe on the Brillelli initially. The brillelli gives maximum thrust on an APC 18x8 and 17x6 props. What size of prop would you suggest as a starting point on the pipe? Also, does anyone know the distance between the mounting holes on the MVVS 3265 header? The distances on the Zenoah and Brillelli are 34mm and 32mm respectively. Thanks in advance. MSS.

RE: What do you have your conversion in???
Tantel is referring to the Briggs Fource 34cc and 40cc weedeater engines. I have not seen any of the 40cc advertised recently. Have you thought about a Honda GX35 or a Fuji 35cc instead? Both are more expensive than the Briggs but produce more power. The Fuji is found in Robin and Makita strimmers in Europe. Conversion parts for the Honda are available form Carr Precision, not sure about the Fuji any more. I have the Briggs 34cc, Honda and Fuji converted for aircraft use so if you wish to see photos send me your email. If you want more than 40cc, there is the Stihl 65cc that Ralph Cunningham and others have converted for aircraft use. You will find information on all these conversions on RCU - just do a search for each name.
