Nova .12 Keep On Tuned
 

I figure we need a little excitement on this part of RCTECH! I am usually a free-rider but today I bought a .12 Keep On Tuned Pre-Broke-In from my local hobby Shop (Playmore Hobby) and of course--as a person who strongly believes that nothing compensates for average driving like a great engine -- I opened it up immediately.

Before I begin, Roelf and Stefan, I like and appreciate your posts, but please spare me a hard time regarding anything I say. I am a "happy amatuer" and likely to stay that way.

I have had a 353, Flash 3 and Flash PT and what I noticed was differnt about this engine is:

1. I have to shim 0.5mm more behind the flywheel to get 9.2MM on the crank (per NT1 manual) so I think this means that either the crank is longer or with the new bearing design, the crank sticks out more because of the new bearing.

2. I remember my first 353 that went rich during a race after 1.5 gallons. In fact all the Nova's I have had were always very tight. The new Keep On that I have is loose in comparison. See the picture where I can hand-turn the piston to the top of the sleeve, in the sleeve without the sleeve coming up and out of the crankcase. All I have in the engine is a little engine maint. oil.

Enjoy the pics. The tuning is very evident on the sleeve and in the case.

BTW these were with an iPhone. First one looks like scratches from the conrod, but I could not see anything on the bottom of the conrod, so maybe just (oil) streaks of some sort.

Check out the piston at TDC easily by hand.

There is nothing like hope for superior power! :nod:

id like to say for a motor you bought from the hobby distributor this thing looks good ijs :nod:
