the AQ site says the nitro MV deuce is 5lbs rtr so im not sure where the extra pound is coming from, thinking most of it is the batteries.

after looking over the set up a little more I think different batteries may be in order. On a 3 min run of almost wot i burned through 3000 mah so lugging around 6600 in the form of 2 4s cells at 3300 mah a piece, wired in parallel of course. Weight with out Batts is closer to 4.5 lbs if i remember correctly. I did try out some 2s 5000 mah 20c packs but they didn't seem to have to dump I want.
Boat is running much better now though.

Going to run some 50% nitro in my stock Deuce, should I leave the head shims alone or remove 1 or all?

Experiment...I have ran 50% and 40% and settled on Byrons 40/12. Read this thread towards the middle pages and AMAX and ToyotaTrucking havegood insight on the shims and head spacing. You and I are in the same city. Where do you run your boat?

When you Step Up the Nitro% you need to put the motor through a Break In Period Again. Start with all shims in for a tank or two and see how it likes it, how the plug is burning, tunability, etc.. If your Not burning plugs up Quick remove a shim and try it again. Make Sure you run Cold Plugs, I have a a lot of good luck with McCoy MC9's running 50% and up. I have Never Touched one of the engines from the Deuce so I'm not sure of specific Head Clearance(Squish) or Combustion Chamber Volume\ Compression Ratio etc.. You just have to experiment. Ideally you want the head to piston clearance tight .004" to .006" in. and adjust chamber volume to the compression ratio you want\need.

Thanks! Waiting on my MC9s to come in now, they should be here by the weekend. Think I'll get me some plastigauge and check the head clearance.

because of the head shape at the squish band, plastigage is not very accurate at that tight of a gap (FYI a piece of notebook paper is Approximately .0035" to .004"in just for reference) a good set of Calipers and some Small Solder works a Little better.
The Squish band on the head Looks Almost Flat but is is actually tapered somewhere around 3* degrees the very outer edge of the squish band is your Tight area and where you want to set clearance.
bend the end of the solder so it will go in the glow plug hole and the tip will touch the side of the cylinder wall, then turn the crank over a couple times to squish the solder, remove it and measure the tip with the callipers.

It's not mine it's an Old Trick. Make sure you get the smallest solder you can find your trying to squish it down to the thickness of a piece of paper.

when i was running the vegas the 535/2 or 435/3 were my favorites- start with sharpened and balanced, polished is preference and modify from there, the box stock grim prop's have fat blades that are ALMOST as sharp as butter knives ALMOST, everyone ive had in my hands was Close on balance but NOT balanced the polished finish sure sells a lot of them im sure of that but if its a worked prop it will be better
