I'm very patient...these little buggers and R/C in general have taught me the real meaning of "patience"....jajajaja..you know what I mean. Anyway I'll enjoy my signature more when it arrives.

What dates are the Winternats?? I might try and make it to watch and or help anybody who needs it. Last time I was there was in 2002...great race and lots of fun...I went with Maxy, from Maxy's fuel that time.

I'll try .014 head clearance this weekend with my M. Collari Sirio, with the 77 plug, also since i'm experimenting with pipe issues on the Sirio's, because beeing a mid-sized conrod engine I think it will work better with a longer overall pipe, so I'm trying this weekend an RB 402 in-line outlaw pipe with the header of the Mugen P010002, which is longer. What are your thoughts about this???

afm going to have to do a little looking to give you an opinion.

peak haow about fridays at 6 pm pacific. however this friday I will be out. so sat at 6 will work. maybe ed will chime in.

afm the serios work good on the turboII with the short header. we sent 12 pipes to team kyosho for the fw05 for the worlds but they opted to run the rrr so they ran serio pipes. Some of the kyosho guys ran rd turbo II pipes at the nats with great sucess. Cyrul, Tossolini. I was told iot gave them the bottom and top they were looking for. I can tell you josh's car was really really fast he just had other issues that plagued him. then again he drives so hard into the corner its just scary, might have been totally optical

Ok, I'll try it and let you know my feeling about that pipe combo I've prepared.
I just measured my head clearance and it is set at 0.16. Let's see if i can get away with it.

There's two friend drivers at my track tha have the RD Turbo II pipe, i'll ask them ..and see if one will lend me his pipe and try it out...but how do I know if they have the short header on them??...what would the distance from the farthest point on the header to the beggining of the convergent cone to determine which header they have???

Do you have the dates of the Winternats???ç

Nitro+ = TORQUE BUT LESS RPM (however it is a huge torque gain with a small rpm loss so?)

Dennis....so what's the recommendation for 40% using the short rod motor? Thanks.

Dennis that sounds like a plan for the Chat....I'll spread the word.

Thanks for the reply Dennis. Do you know if you will sell piston sleeve sets and crankshafts for your engines? I have an STS engine crankcase that I can use.

Have you tried putting your piston sleeve into a Nova crankcase with the Nova crankshaft? I guess if I wanted to use the RDLogic piston sleeve in a Nova crankcase, I would need to cut the groove on the top of the sleeve on the exhaust port side to fit the pin groove on the Nova crankcase. :sneaky: :D

Regarding chat, I think you could go to www.3hobby.com and register to be able to use the shout box. I don't think Sow&Steady would mind you guys using it so long as it's RC related. :nod:

Hi Dennis got the short rod motor today , looks nice!!

just a note for all who get one and if Dennis agrees,
my motor felt like it had pinch all the way to the bottom of the stroke, so i took it apart and clean it with after run fuel,
i didnt notice any metal or grit from machining but when i reassemble it it spun freely as normal except tdc ,
the three motors i checked all did the same thing ,
so either they are putting a thick coating of something when they assemble or they just need cleaning before you run them??
maybe you have some input here Dennis??

ok now for a ? i added a shimm .10 to make it 5mm total motor came with 3+1
i didnt check piston to head just went with what you said ,
maybe i check it tomorrow,
anyway after break in i notice that high side needle was less the 1 turn from closed, about 3/4 = 5/8 to make it run well,
i know there is no one setting for all motors but is this in the ball park with what you have found with this motor ??
Thanks BC

bcquick 11-04-2004 08:02 PM

power aside would there be a run time differance between 2o and 40%nitro
thanks BC

Yes.

Carb
 
Denis i see on rd logics site it says 5.5mm for carb is this a typo or does it mean its ilegal for EFRA 5.4mm??

That engine looks nice. I would like to see a few more reviews and testimonials of people that have used this engine. If it sounds good, I may have a new engine for that FW05 come springtime. Couple that with the hard coated pipe, and it will be a wrap

Motorman007 11-05-2004 02:57 PM

Dennis R how are you man? i hope things are well.

are you still running the Mac motors?
also do you still mod Off road motors?

thanx dibs.

D,
I'm surprised at you - don't be so stingy. ;)
A whole new RD/Richey engine is only about US$180 and you won't have to worry about your second hand bearings and what "might" have been done to their crankcase. :D

gonzoY5 11-06-2004 06:30 PM

Any "normal" racers try one of these out yet? By normal I mean just a regular dude. I'm curious at how they perform for the Average Joe. If they're as good as advertised, it could put great pressure on other companies to make their prices more competitive.
