Well I ran my D3R for the first time last club meet. (Have been using a D5)

Result?
Fastest lap time = around 1.5 secs faster then I have done before
Don't know if it was me having a good day or the engine

Now to try make each and every lap fast...

The carb insert can change the powerband. Also different fuel consumption. You can try both and choice what you like. But you need to adjust the carb every time after you change the setting.

Dino, just got my STS D5R yesterday. What's the factory recommended needle settings? The build quality looks great except the carb is slightly rough, but that's okie since I have an additional new(?) STS carb, which I have checked is as smooth as the nova.

I am planning to run on 25% nitro, so is the factory adequate to it? Will break in the engine this afternoon with Maxy break-in oil.

Dino???? Still around? Need some advice urgently.

Just broke in then engine and have now run 5 tanks on the bench and about 3 tanks on the track. In fact have started to lean the engine. I notice the low end is still very rich despite leaning the HSN. Engine temperature was 130C. It was still very rich at that temperature with plenty of smoke visible. The local racer who is using this engine suggested to remove one of the copper shim as he had done. Is that alright? We are running 25% nitro here, and I am using Nova plug No.6.

Thanks!

Try 0.4mm shims with 25%. And cold plug due to the weather is hot now. It may stall due to ignition timing too late

Hi Dino! I m having trouble tuning this engine. It seem that it has got no low end punch. Pls help! The situation is like this: Top speed is good and idle is good too, very stable. However when I punch the throttle out of corner especially into the straights the engine seems very slow picking up speed and gives out a lot of smoke ( sounds very rich sometime it bogs too ), then after half way down the straight it just rocketed as fast as the novas. I try to lean out the main needle but the temp is already very high ( today I temp it around 130-140C However it never showed signs of overheated ). I also lean out the low end but still the punch is not there. The only needle that I haven't touch is the middle one. 3 of us here who use D5R are having the same problem. I use 25 % Gammalube fuel and p6 os plug also runnimg 0.5 shims. Is this normal for D5R? Also the high temp that I mention earlier is that normal too? Normaly I tuned my Novas max is 120C.


Dear Dameetz,

From your statement it shows the igniting timing too late. If I was you I will try to adjust shims' setting first. Take out 0.1mm shim to make it only 0.4mm totally,then readjust the carb. It will be good for low end acceleration. If it's still not enough to you,turn in 1/2T the mid-range needle also turn out 1/2T low-speed needle,or longer the back compression line.

When your engine has many low-speed punch,you will not lean it too much then the temp will be lower a bit. When the weather is very hot like over 35C here,the engine temp will be hot too. The new D5R is very strong so 130-140C still ok but you have to make sure there are smoke out of tail pipe always. When it still has smoke the temp will keep in normal range but when the smoke gone the engine temp will fly to very high. Sometime I will only use this as my adjusting principle when the weather is very hot(over 35c). Because if you rich it,you can't win.

Thanks Au.

I removed the copper or brass look alike shim last evening (any idea on the thickness? 0.1 or 0.2mm?). Have not tried it yet today. The "symptoms" I had experienced yesterday is pretty similar to what dameetz posted. Idling and top speed were great. In fact the top speed is as good as any engine out there, but the low end punch was missing despite leaning the HSN and engine temperature was hovering around 140C but plenty of smoke from the pipe and no signs of overheating. Will try it again this afternoon, and hoping for some good results.

p/s can the nova M Speed back plate be fitted on the D5R without it being scratched?

The stock D5 come with one 0.3mm alu. shim and one 0.2mm brass shim. You need to replace the 0.2mm brass shim with 0.1mm one. You will feel its different.
RE: backplate, no idea.. whats the attraction?

Hey Dino:

I have a question for you. RC-Mushroom is selling a D5R modified. Is it factory modified?

The Brasilian distributor for STS is www.hobbyracing.com.br
They will have the D5R in stock shortly.
They can solve this and any questions.
Ask for Marcio
