Wanting some input on mod-zenoah v.s. quickdraw pioneer. I know I know, the shame..

[pond skipper]

So for some reason lately now that I've finally got my 33" seaducer p mono screaming the way it should ive developed the urge to build a 42" seaducer sprint gas mono "I know, I'm ashamed" but for the life of me I can't manage to figure out which is better a full mod zenoah or the quickdraw pioneer series engines. I have no intensions of heat racing but rather to see just how fast I can make it go on the big end and I'm trying to figure out which one would be best suited for that task. So if anyone has had any experience please feel free to share, I would like to keep it under 27cc and be able to run over 80 but if that's a bit far fetched I suppose going bigger on the displacement won't be to bad, just don't want to end up overpowering the boat.

Hey,
You should ask Mac and Tag aka Stephen in this post.
They run a lot of gas boats and some FE stuff to.

Check out the IMPBA web site in the Record Holders section and that will help answer your question. 80 mph out of a gas mono is a lofty goal. But it's been done. There is no doubt Quickdraw makes a nice motor, but there are plenty of builders out there can make just as much HP our of a Zen and at a lower cost. And IMO the power difference between a well mod 260 and the newer big blocks is not as much as you think. The records reflect that also.

Well scratch that then, guess ill be sticking with electric

[Chilli]

Hey gas is fun too!! It's cheaper than electric in boats over 40 inches and run times are a heck of allot longer.

Mod zenoahs are popular in NZ, most of our clubbies run them, bear in mind that if you mod to get big hp then you lower the reliability and lifespan. One clubmate through a rod at the nats, destroyed $1600 worth of motor! Personally I think they're nuts, $1600 would do nice fast electric setup!

has anyone ever had any experience with J&G gas Engines?

[RaceMechaniX]

Honestly I would not select the Seaducer for a gas mono. It was not nearly as successful as the nitro and FE versions. I have Zenoahs, QD HR's, QD HT's and JG's and none were stable enough in the hull. It is very quick, but in race water it is tricky to say the least.

As for engines, perhaps the most important detail is what is available to you locally. If you have a local a Zenoah engine builder or your clubmates have them, run a Zenoah. If a friend is knowledgeable about QD's, go ahead and get a Pioneer. QD's are very nice motors, but need more care and maintenance than other's. They will run as strong as any good Zenoah when set-up correctly. Another important detail is whether you plan to race with one. At Least in NAMBA QD's, JG's and CMB's are only allowed to run in the modified classes where as Zenoahs, CY's and RCMK's can run in the "stock" class.

Lots to consider.

Hello,

Yes, I have. Its my favorite! It runs like a fine Swiss watch. I really can't say enough good things about it. To me, they are outstanding in every way!!!

[pond skipper]

Well I won't be heat racing for sure, there's no clubs anywhere near where I live and aside from a few of my friends having some RTR boats so I would basically be on my own, my dad and I ran 60-80 and 90-100 monos a few years back but the club closed due to the people complaining about the noise so the city shut us down. But I have a good friend who lives on a ski lake and we run our boats there now. The reason I wanted to go with seaducer is because I'm familiar with them already and because they are very fast. I had a 90-100 with cmb91 and loved it but didn't love the price of nitro fuel, I have a 33" seaducer that's set up as a full p-mono that hauls the mail! Plus I'm a bit of a speed freak and I love monos.

[pond skipper]

What cc, boat, and prop combo are you running if you don't mind me asking??

[RaceMechaniX]

Likewise I have a 21 and 101 SD3 which runs great, but the SD3 gas mono I had was a nightmare. I set it up per the instructions and it was a wild boat. I can tell you from experience the gas mono does not behave like the nitro mono's do.

Just my 2 cents worth of caution.

[pond skipper]

What hull would you recommend? And just out of curiosity what bad traits did the seaducer you were running have, and what prop were you running on it?

[RaceMechaniX]

I would highly recommend the Y6 from Ron Buck or the Calcraft from Rum Racing. Both are excellent boats. I run a Y6 with a Suicidal Zenoah and it is pretty competitive for speed and handling. Runs better in race water than flat water and has good set-up details.

My Seaducer ran very light in race water and tended to dart to the right or barrel role. Granted I ran this with very aggressive props: X472's, SD3 Gas pitched up, CMDI 6720, X460/3 pitched up. If I ran the boat with a stock Zenoah it was a great boat, but the difference between the mod motor and stock motor was night and day.

Thanks for the info man!
