Just gauging the consensus with liner pinching on whether it works or not, limitations and experiences by those who have tried it.

This may be a loooong shot, but wondering if anyone has a new piston/liner or rod for this motor buried in a draw or cupboard somewhere? Cheers Tim

Just chasing different GPS brand/model options (review/opinion) for model boats and where to purchase. Happy with waterproof and non-waterproof models. Looking for simple good value unit (Garmin to $$$$) Cheers Tim

As per Topic!

I have noticed that the outside edges of the exhaust port windows are close, but don't match the case. Other than the port top edge, is there any benefit in matching the side and bottom outside edges to the case for the returning pipe pulse or would this impact on the earlier exiting exhaust...

I have read two different ways to calculate the compression ratio which involves either the full cylinder swept volume or volume from top of exhaust port to TDC. My questions are: does either method matter as long as you always use the same method? what ratio to aim for with 50% nitro (non...

Trying again Chasing a second hand pitch gauge, Orlic or Hughey shipped to Australia. Cheers

The JAE 45 since conception has gone through a number of versions and design modifications. I am wondering whether there have been any advances or recommended updates for the JAE 90/101 design prior to starting my new project. Cheers Tim

Hi all Tom Foley gave me some great advice on starting points for a CMB 67HR. Just chasing the same starting points for the 45 with 50% nitro in a rigger. Pipe length? head clearence? and particular plugs (I use high nitro K&B on the 67)? Cooling hole size? Anything else I should know...

Let me know what ya got that you want to get rid of and for how much. I'm in Australia. Cheers Tim

I have read before that when you get the prop close to fully balanced, you end up in a situation where you need to take weight from either the tongue or outer edge which is dependent on how the prop settles on the balancer (generally more horizontal but preferring one side with tongue down and...

My new model boat club has some strict noise restrictions. A standard nitro pipe (small volume CMB 67/80 pipe) and stinger is too noisy on the 67 rigger. The alternative pipe options I am looking at is the CMB AB.67 Quiet Pipe or an AA .67 Parabolic pipe. Any suggestions or advice on the...

If someone could please direct me. Cheers

Not after anyones secret mixtures here but any help is appriciated. Just chasing a starting point for a basic fuel mix for a stock CMB 67 in an SGX for club day racing. Happy to run 20 - 25% Nitro but it's really the oil ratios I'm interested in. What are the total minimum safe oil ratios...

I understand that the Octura X series props are non-lifting, and the 14 and 16 series are medium lifting props. Why??........ There is obviously a blade shape difference but what's in the shape that effects the lift characteristics? An experienced boater looked at a prop on the...

Pondering a powerplant for a new 45 Rigger and the AAs appear to look like a very nice engine! Just wondering what the general consensus is with the AA 45 ? Any comparisons with the Nova from anyone who has run or is running both? Any specific issues I should be aware of (weak cranks, rods...

I have a CMB 67 with the CMB small volume 67 pipe. Could someone please point me in the direction of someone or store that sell mufflers/stingers. Cheers Tim

I have unfortunately removed the bottom end needle as part of blueprinting the motor and have forgotten to take note of the low end needle setting. If someone could please give me a rough setting with the carboy fully open, and the low end needle screwed all the way in, how many turns back from...

Just chasing what type and starter setting for this remote needle?? Thanks file://localhost/Users/timvanschyndel/Desktop/photo.JPG

I have a rebuilt SGX 67 which has a removed centre rear sponson. Just after a general starting point for height and angle. Cheers in advance! Tim
