Rcosmax, which pipe are you using currently and also what is your LSN and HSN settings?

I notice that the STS sleeve is well made but the piston seems to wear off pretty fast say compared to the Novas? The novas seem to be the other way round, well needless to say I use the nova piston and STS sleeve and it was a nightmare to break in

Sorry Bundyman. I dont know where my needles are at now. I really dont like screwing them in to bottom them out and get a baseline, it is just too easy to damage a needle seat/needle. I could give you mm in from flush though if you like.

I have to check on #'s tonight but i can say which pipes I have tried. First was the sts tunable inline. I was still on breakin and when I had the flameout issue I changed to a milke 6mm pipe and after realized the lsn was the problem so havent switch back to the sts to try again. I also ran a nova 6mm but it didnt like that pipe so much. seems to run great with the milke, but I want to try the sts again to compare now that I know were the tune is.

Could you give a part number on the Nova piston you used? My experience with novas are all micro cast pistons and I hate them because they wear soooo fast. I only have a little over 5 liters in the sts d5r now so no wear to speak of yet. Did you run the sts piston to the ground and then replace with a nova piston and re breakin, or from new with the nova piston/sts sleeve?
cheers

Well, I did break in the STS engine and run probably about 10 tanks after that and measured the sleeve and piston before and after. My conclusion is the STS piston wears out pretty quick compared to the Nova but the sleeve seems more durable compared to the nova. It took me awhile to break in the STS/Nova combo I had replaced the conrod as well as a precaution. Have not race tuned it yet.

hmmm interesting. In my sts.28 i would say the piston material is bang on with the expansion ratios giving great compression even at hot temps. From my finger spinning the flywheel in my rrr the sts d5r seems the same. I wonder if it is because the initial piston dia/size is tighter in the sleeve leaving more material to wear in on breakin and this made the larger difference before and after? My sts .12 d5r was hot on breakin even spitting rich. I had chalked this up to a tight pinch with a lot of material to wear in on breakin.

Which nova piston did you use....? did you use the sts rod or nova rod? Are the rod id bushings the same on both? I am always curious when people run different combos thanks for taking time to answer.

I am using the microcast piston from the NSR and together with the STS conrod (much cheaper LOL)

I actually purchased 2 sets of STS piston sleeve and both showed similar results after breaking in.

WOW I am surprised you have experienced good things with the micro cast pistons. Maybe it was just me and the guys at my track that had bad luck with them. We had all come to the conclusion that they dont last as well as a standard piston. Very interesting.

how are you getting just the piston only?

I, too, am thinking about getting a set of STS p/s for NSR as well. Should I go the nine yards and get an extra con rod? Will it fit in the NSR?

I invite to all southamerican pilots to give a chance to Alfonso (AFM) to show you his excelent client service. Usually we, from southamerica, just have access to buy from USA 'cause we dont get good service and prices from southamerica itself ... Alfonso is a pilot too so he knows exactly our needs on this hobby and do his best to give us the best ...

The engine and pipe its just in my house (4 days after i ordered !! ) and the model kit its on its way to my house right now ... and 2 other friends of my RC Club are buying RC Material from gppmodelracing too ! (www.gppmodelracing.com) ...

Well guys, sorry for the long post but i had to do this ... hope to do bussiness with you Alfonso and keep up with the excelent work you do !!!

PS: Bundy - any special price?

I may run it this weekend. NSR crank, piston with STS sleeve. The last time I broke in the combo, experienced plenty of low end torque but the STS carb got stucked This time will run with the Nova carb and see how it goes.

Now thats a hybrid! I'm close to buying a sts motor probally for my r40. I don't know weather to get a 3 or 5 port though. The clubs in my area don't care as long as its a small block. Would the 3prt make considerably more power than the 5 port? Which one is the easiest to tune?
