Hi!

Recently I've taken off my engine to clean it.
Now I've put it back in the Ravager.

But I lost my HSN setting. (I played with it when I cleaned the engine)
So I had to tune it again.
But now I'm having the right temp (250-260).

I also did a lil' bit of drifting with it in the morning.
But I didn't went full throtle. (I only gave little tap on the trigger)
And the engine was running like 200-220.

My problem is:
I switched back to my road tires.
When I go full throtle, the engine seems to be on the edge of stalling.
It even stalled once.
So I don't know if it's because of a bad tuning or the drift damaged the engine.


I'll take a look at the engine, but I don't think it's broken because it runs perfectly before hitting the high RPM range.

i doubt that any "drifting" per say caused this. This sounds more like a tuning issue than anything to me. If in doubt, try and find the default factory needle settings for it, then reset the needles back to those defaults and re-tune from that point. Hopefully that should get ya headed in the right direction.

OK I also think it's my tuning
but......
It might be a combination of tuning/brand of nitro

When I bought my RC, they sold me blue thunder sport formula (20%).

And on the blue thunder label it's written:

Quote:
Blue Thunder Sport Formula is specifically blended for ready- to- run and sport nitro drivers. Its exclusive ZX- 7 additive provides superior over- lean protection that actually makes engine tuning easier as it protects. Here's how it works. When an engine is over- leaned, internal temperatures rapidly increase. At these critical over- temperatures, ZX- 7 actually changes from a lubricant to a combustible. This alerts the driver to a potentially damaging over- lean setting by causing the engine to bog/ hesitate during full throttle acceleration.


I think my problem's here!

But it wasn't too hot at all!!! (240-260)

I think I'll choose another brand when the gallon will be over (about 1/5 remaining)

Do you have the Force .28 engine? If so you can put the HSN at 3 1/2 turns. Then lean it one hour at a time. Don't lean it too much!! If your bashing hard you want to leave it at a slightly rich setting. And don't do too much WOT with that Force .28. It won't last.

If you can find it in ur area; for a 1st choice of nitro i wouls say go with 30% byrons fuel(again if u can find it) or as a 2nd choice odonnells 30%; as they both seem to be pretty consistant for the most part. The one disadvantge of odonells though i might note, is that its not dark in color so its harder to see when its going through the lines; just a sidenote there is all. Either way good luck getting it figured out

Cool deal. Eiher way I would say stick with 30% since its a buggy/truggy etc type of engine, unless u intend on wanting it to last a bit longer in which case stick with 20%. But doing 20% u wont get as much power as running 30% will give ya.

Will I need to modify something on my buggy to run 30%?

Finally I've bought O'Donnell 20% Ready 2 Run.

I chose this one because I'm not racing this year. Just bashing around and learning how to drive my RC the right way.
Maybe I'll be racing next year if I can find an off-road track near my home. (Montreal's South shore)

Cool deal man. Like i said before donnels is some good stuff which ive used before and had good luck with. As far as the racing part goes. I dont necessairily think one brand of 30% is better than another per say, other than the 2 ive previously mentioned. Its just some will say others out there are better than odonnels and byron's. There are soooo many opinions on this subject matter but never enough REAL truths to it.

I tried the o'donnell tonight and I liked it.

The engine is easier to start and the temperature is more constant.


It's been 2 weeks I haven't runned my baby!
Man that's good to smell nitro again

you may possibly need to add a head shim to run the 30% to prevent detonation i do believe(someone correct me if im wrong by all means)

I chose 20% ready to run.

Correct me if I'm wrong, but if I stay with the same nitro ratio, I won't need shims?

No, u shouldnt need to add shims with 20%. You should be fine with running that. Its when u goto 30% that u COULD encounter a problem(IF u ever change nitro%.
