.12 Rigger / Hydro Engine options

[68Bud]

Thinking of building a .12 Hydro and would like to get opinions on options for nitro power. In search of information on engines, flywheels, crankshaft threads and flex couplers. Thanks

get a hold of glenn quarels on here if you want water cooled novarossi, or some guys just run a air cooled buggy motor. glenn will set you up with collets, cables, struts and rudder. he's great to deal with.

first choice would be the nova rossi from glen. $155 if i remember right. after that would be determined by your budget. look on ebay for the cheap stuff...

 

[Mark Leyde]

Glens Novarossi comes with a flywheel.

what kind of speeds are expected out of a NR powered .12 rigger

 

[Mark Leyde]

High 40's to low 50's in race trim.

That depends on the amount of alcohol involved in the conversation.

I was basing this on my last years rig. That was a stock .12 Picco on road motor. Yes I expect more from my Nova.

We'll find out when the water thins. I just my NR .12 in the mail yesterday and stuck it in the hull tonight.

The Nova Rossi is THE engine to have now for any .12 boat. I've tried a lot of them over the years, mostly car and truck ones as there wasn't much else on the market. OS's aren't bad but they sell them for a while then poof, they're gone. I've been building .12 powered boats for a good 10 years so if you need any help maybe I can help.

Most .12 sized engines that I've looked come with a slide carbrator, what is a good repacement rotory carb for them?

Hey Joel, The OS TZ.18 rotory carb works good. Glenn Q. also has a Novarossi rotory carb for the .12's that works great.

Are you thinking of joining us at the nitro pond for some of the greatest A hydro racing in the USA.

 

[J Solinger]

What is the number of that carb? Is it the 11L?

God knows I want to. I havn't been able to pull it off for a couple years now, I've been too busy with fe.

I have a 12 rigger that just needs some finishing up. I came up with a way to use slide carbs but I realy don't think it will hold up and need to switch it to a rotory.

It is the 11J I think. It is the some carb that is used on the .18 CV-R OS marine engine. I wish I had a part # for you for the Novarossi carb. It cost less than the OS. Send Glen Q. a PM and ask him about the big carb that he sells for the .12's.

Hello Joe, I have a Zoom 12 that works extremely well. It will be avaliable by the time that the water gets soft.

If you can't wait for the Zoom, I'd try the Nova Rossi carb. I compared it to the reworked .21 Nova Rossi carb that I have on one of my other .12's and the bore is almost identical.

Most other .12 carbs are restricted because of ROAR rules to a 5.5mm bore.
