I'd like to see some flight repotrs. Getting ready to put some new life in my Raptor 30.

started flying the motor yesterday the motor would not start right away
the idle screw had to be set at 2.5 turns out after i did that it started
and idled good .
i let it run for about 2-3 minutes no sighn of being to rich or lean and it trasitioned to hover no problem the first thing i noticed was the lack of smoke i run cp 30 and i opened the main needle 1/2 turn more and it hovered fine the instruction said to set the main at 3.5 turns out but mine is at 4 and it just purred like a kitten.

i put two tanks throught it and started banging sticks way more power than my os 32 and the pipe gives it a noticable sound not raspy but you
know it is a pipe i was using 550 blades but i think that 575 or 600
will be better it wanted to over speed the a little the bigger blades will load the motor better.
after the third flight i leaned it up about three clicks and the last tank
lasted about 25 minutes i was running this in my evo 30 with the bigger tank with my 50 i was getting about 15 on a tank.
in my opinion it has almost as much power as my 50 but with longer flight times.so far the motor runs good and i am very happy with it


thanks jeff

sweet, I can't wait to get one. Buying a Toki .40 is a lot cheaper than buying the raptor 30 to 50 upgrade kit and the OS 50 engine.

I also meant to ask, is the pipe that it comes with a fully tuned pipe? Are you using a governor? Do you think it needs one?

the next questions?

Over the years I have found a good number of heli engines that seemed to work well at the beginning but due to poor carb designs, poor selection of materials etc. either wore out prematurely, became less user friendly with time (e.g. creeping needles) etc.etc.....


so the next questions would be, How is it doing after 150 flights? (all my OS's have now over 300 flights on them) How is it doing after 300 flights? etc.

IMHO, power without reliability, dependability and reasonable life expectancy before reasonable wear dictates replacing components is useless unless racing.

I'm going to politely disagree with syclic. I don't mind replacing parts as long as it's not due to a crash. If my engine flames out and I crash then I'm upset. But if my engine gently wears and warns me that it's about to die then I'm not upset, no matter how long it lasts. All engines made on modern CNC machinery seem to be pretty good about wear. I know a guy that has burned an entire 55 gallon drum on the same YS .61. I personally have never worn out an engine.

Insane3D,

I understand what you are saying - my favorite 60/80/90 engines are YS (can't wait for the new YS50H to land on our shores).

"IMHO, power without reliability, dependability and reasonable life expectancy before reasonable wear dictates replacing components is useless unless racing." addresses exactly what you stated. So we agree.

Maybe I should have expanded on my brand list and made myself a little more clear.

My post re: trying many engine brands, was more to address those brands and/or models that are not mainstream or proven in the R/C helicopters community.

For example, many of the chinese manufactured units may have different names but many come from the same manufacturer - e.g. Magnum, SC., and the many others manufactured by SC. I have wasted a lot of money over the years trying many such unproven brands in the hope of saving money or discovering better performance. What I found was engines that would go from 30 to 50 flights before taking itself to bits because of a broken con rod, peeled chrome/nickel plating, failed piston ring or premature bearing failure.

All of this in reference to the inituial question is that I will wait until a good number of others have used an engine in hard 3D for 300 plus flights. Only then, if it is still in relatively good condition, producing good power will I consider it has proven itself worthy.

I have had a number of brand name engines also not prove their worth, but the risk is not so great, and usually they have at least ran well for 130 to 150 flights. They are not as much of a "lottery" purchase as is a brand that is totally new to the scene and unproven.

toki is unproven alright, but MRC and Jeff Green are proven.

7 flights on the Toki muffler.

We installed the Toki on a Cal 30 with OS 37. It is a great fit and should fit under the FT canopy if anyone was wondering.

The muffler runs real smooth in hover and is noticeably rich. It does have a tinny sound compared to a Funtech or KSJ. It really kicks upstairs and has a tuned pipe effect as you can hear it get on the wave at full revs. The muffler added a 100 rpm to the head speed and that is running rich. Headspeed with 9.5 degrees of top end pitch were in the 2000 range. We added some more top end pitch and got the head speed to settle at around 1950 on the climbouts.

All in all, it is worth the money. The pipe is well made, the welds are clean. I like it enough that I ordered one to replace the KSJ that I'm using. I don't want to give up anything in the HP race.

I ordered the Toki muffler this morning for the OS37 in my Caliber. Can’t wait to see what it does. I’m sure it will be quite drastic considering I still have a moded Caliber 30 muffler on it. I also have the FT canopy, so I’ll keep you posted on the fit under the canopy. If TMoore likes it, I’m sure it will rock.

Let us know how the muffler really fits in an FT canopy that is fitted up. We just held the FT canopy in place and from what I could tell it looked like a great fit with plenty of room up in the front of the canopy.

Flew my TOKI in my Caliber today. It has lots more power than the OS32. I am having some tuning issues though. But, have only run 2 tanks through it. Will continue tomorrow, to iron it out. Having some slight overspeed issues too, but will work on curves. Boy, does it go up when you nail it! Sound is pretty neat. Seems to have no overheating problems with that big head.

I would expect overspeeding if larger blades are not used.... Toki/MRC recommends 600mm (50 size) blades, not the 550 (30 size) blades. I'd be willing to bet that 575mm (40 size) blades would be just right.

Well here is an update on the Toki muffler. I received it yesterday morning and it looked great. It was a no brainier install on the OS37. It fits perfectly. It clears the tank easily and fits under the Caliber’s FT canopy better than the stock muffler. There’s plenty of room. In flight, after some retuning, it created a lot more power. It finely flew the way I’ve been wanting from the day I bought it. It was awesome! It’s no 50 but I couldn’t ask for much more. It flew so well that after 3 tanks, I few it right into the ground. Just my luck. It was bad. It’s probably totaled. I haven’t had time to disassemble it and find out what’s salvageable. My carbon blades virtually exploded. I never found all the parts. But the muffler worked great. The sorry thing is that when it hit the ground the blades folded up onto the heli it’s self pretty much shredding the helicopter and totally scratching the fire out of my brand new muffler. It will still work but it’s not so pretty anymore. I highly recommend the muffler, but I don’t recommend crashing on the 3 fight of the day.

Wheelnet1,

sorry to hear about your poor luck. Never fear, it happens to all of us, sooner or later.

As for main blades, I have a TT39 in my Ergo and it swings the 600 mm, NHP, carbon razor pro's, no problem. These blades have a narrow chord and are tapered ... ideal, I'm sure, for the Toki 40, as well.

Yes…. The Toki muffler and an OS37 will drive your heli into the ground much more efficiently than an OS32.
