Hey folks, I just picked up a NOS older Cipolla PAS .21 marine, for what I think was the right price. What can I expect from this engine? Good performers? Do they stay together OK? Thanks for any info. :) Duane

Hey gang, just wondering if anyone runs or has tried a NovaRossi 50042 Super Silenced tuned pipe. Is it decent, or a dud? Thanks, Duane

Hey gang, while thinking of fun projects to do with my new little toy lathe, I thought I'd make some .21 size tuned pipes and have a local guy weld up the cones for me. I'll probably make copies of the "shorty" Irwin pipe I have (at least I'll give it a try). Will 6061 alloy work OK for a pipe...

Hey gang, are any of you familliar with the physical differences in the various Aeromarine cable collets for popular .21 engines? I've emailed Aeromarine, but received no response... I want to know about the #s 1700, 1718, 1724, and 1732. I need to know the diameter and depth of the flywheel...

Hi folks, I finally bought myself a small 7x10 lathe for hobby use, and want to make a few .21 size flywheels and cones to convert car/buggy engines to marine. My question is, about chucking reamers... The cranks have a 7mm shaft. Should I use a 7mm chucking reamer to bore the flywheel cones, or...

Just wondering how far below the sponson bottom a sport 21 turn fin should be, and roughly how big to make 'em... Thanks! Duane

Hey folks, can any of you offer suggestions of easy ways to skin compound curves...? I'm finding it very tough to get 1/16" plywood to lay down on some sport 21 sponson tops... What's the hot tip? Thinner ply? Special clamps...? Thanks, Duane

Hey folks, I'm wanting to convert some short stroke NovaRossi based car/buggy engines to marine, and could use some good (not chewed up) flywheels, head buttons and cooling jackets. Got any dead Nova short stroke marine engines laying around that you'll unload cheaply? Could also use decent...

How many people leave the tail end of the belly pan open to let water out, or have a drainage hole at the back? Is that a bad idea? Thanks, Duane

Just wondering if anyone has played with the less expensive Nova 3 and 5 port .21s with the 13mm cranks. THIS ENGINE is the one I'm asking about, and it's sold under the Nova, Rex and Top brands. I see them new on eBay for $140 shipped (the 3 port)... Does this engine share much dimension wise...

Just wondering how stiff a rigger or sport hydro hull needs to be for proper handling... Must the tub always be as stiff as possible? Is a bit of flex OK, or never good? Thanks! Duane

Hey gang, just wondering who here has built and is running Bob's RHT Marine "rigger style" sport 20 boats... (the one that created a bit of controversy..) I'm just starting to assemble my wood kit, and was hoping for any building or setup tips Bob didn't mention in the instruction sheets. Can...

As Rod G mentioned in another thread about a vintage hull kit, the Japanese are going very fast with modern, refined Delta style mono hulls... They were once somewhat popular here in the US as well, but are no longer... WHY? What happened to the Delta hulls? For folks who haven't checked out...

Hey gang, have any of you seen one of these running? Were they competitive in their day...? How did this type of hull drive; I mean, did they slide in corners or do strange things in the straights...? I'm guessing it's a mid '70s kit. Had to snag this off eBay; the kit was made 'round the...

Hey everyone, I'm working on gathering up equipment for my new fueling and starting field boxes, and wondering: what's your favorite type and brand of fuel pump for pumping to/from can/bottle to tank? Should I go with a fancy electric...? Go with a hand crank unit for reliability...? What...

Hey gang, just wondering if anyone has a picture of the "glow beast" plug driver that they'll share, and also physical dimensions and specs on them... I'm wondering where I'll put one on the new starter box I'm working on... Thanks! Duane

Hey folks, just looking for some set-up info on the AXE Rossi slide valve carbs with multi needles... I picked up an AXE Rossi "Black Magic" .21 (the low-end grunt version of the high RPM Maranello), and it's got more needles than I'm used to... BTW- this engine will get the sleeve ported to the...

Hey folks, I often see people recommend Cooper, Irwin, CMB pipes, a Novarossi pipe, CMDI pipes, Salisbury pipes, an OPS pipe, etc. Rarely do y'all talk about the Macs Products pipes... Why? Too expensive? Don't they work well? Or, as appears to be the case of the Rossi Piranha .21, are they...

Hey gang, is there any brand of commonly available (Home Depot) urethane wood finish that will hold up to a nitro spill? I'm almost finished putting my new SIG Fieldboss box together, and need to finish it. While I could go the thinned epoxy route, I'm hoping for an easy to brush urethane...

Hey gang, I know that many people use a 3rd channel needle on all their boats these days, but are they really needed for club racing? Are they more or less important depending on engine size, like just as important on .21s as on .67s..? I'm trying to talk myself out of using one on a new 20 mono...
