new engine for z class ????
« on: November 04, 2007, 10:40:38 AM »

Hi guys, I,m new here, but have been an OMRA member for many years, a few may know of me. I still have my A class boat and also a cobra GT, with a Zen 26 fully lightend and running on a "coopers" pipe. ( my surname but not my pipe ). May pluck up the courage and race it for 08. I have mainly been racing Z class now for a few years. Anyway, back to the subject, I have poss found a new .12 engine. The car boys have a newish make of engines availible called "GO". This is the baby .12 rear exhaust goes under the name of Hong Nor ( with help from Force engines )  Found one on Ebay ! - item 260178336994.  buy me now 40 !!!!!!!!!   I dont know of any performance figures. Any Z boys out here poss reply. 

Cheers,  Gary.

I know that Andy Payne does work such as making marinised heads for car motors, give him a shout and he might be able to help you out.

   if you only need a flywheel, and not able to make one give just-engines a ring  01228 712800  www.justengines.co.uk
ask for the ASP or LEO .12 flywheel and matching collet.  O0
I have done this in the past but now use OMRA members who are able to make me a water cooled head and a flywheel or I use one of our club members who offers the same service.

What engine are you converting?

im thinking of an sts .28 and it's got a car crank in it, so how would you fit a collet?
but the flywheel is no big deal really because i own a small myford lathe.
i was just being lazy with the flywheel side of things, it would be nice just to bolt one on and not have to balance it.

Hi Pete,

The STS range of engines are GREAT !!!!!!  O0
I race a .12 one on a gearbox in a Datline Cheroke chief mk2. This keeps up with the novarossi.

The main UK supplier for STS engines and parts is CLEVELAND MODELS   01642 241511  www.clevelandmodels.co.uk  if you req the correct collet he should have one for the .28.

There are two ways of doing your flywheel,  in both cases you will have to cut off the plain end of the crank, just in front of the threaded section, using a small disc on a dremel type tool. You are now left with  a plain section - then the thread.
Fit the collet and then measure and work out the size of flywheel that is req,d leaving enough thread to take your coupling. :-\

The other way is not to use the collet, but just have a straight line bore through the flywheel and a small thin washer behind, pushing up agaist the inner race of the front bearing. The only problem that does happen using the second method, is the flywheel has a tendancy to come loose as it does not have the collet to keep it tight on the shaft.

I take it that your engine has a pullstart, so no need to make a groove fo a belt. The flywheel does not need to be very big in diameter.

Hope this has given you some ideas?   :-\
