1750 kv max 14.8v/4S? Isn't that a bit low? Castle's 2200kv's can be run on 6s for short periods of time. Just a recommended rating, or does it have something to do with Sensored application?

Also, the watt ratings of the regular size and the large size are almost identical. Why's that? I assume these are burst ratings, or an average rating of continous and burst, but aren't they QUITE low compared to Castle? Or am I misreading it? Is this cause they are sensored? Sensored is supposed to be considerably less powerful than sensorless.

Yup, more people are finding that there are in deed more and better choices out there, and now that Novak is loosing businesss to shops like Tekin and Castle they are starting to "upgrade" their products in a similar fashion, hense this thread. But to awnser your question people were pushed into buying Novac stuff because when they went to their local track they found (and still find) it to be a ROAR regulated environment where sensors are mandatory, 2S lipo was the limit, and many classes required you to run a very specific motor. All of which was geared to keep the sales pointed at Novak.

And that's why even if Novak clones the very best Castle ESC's, makes Neu motors to the finest detail and sells TRUE 50/100C lipo's for pennies on the dollar versus buying the real stuff, they will never see a dime of my cash.


If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...

Speaking of..

I was marginally interested in the whole debate about R.O.A.R. due to the fact that I hardly race at all. That said, I've listened to pros and cons towards the whole sanctioning body and wondered what the fuss was all about until brushless became mainstream.

First it was brushless motors. Hell, my first brushless setup was a Novak SS 5800 back in 2002. I still have it, and it still works. Granted, you have to gear it properly and certainly won't be going any higher than 2s with it.

Then other companies seemed to come along and simplify things with sensorless technology. Not only were the products cheaper, but they were more robust. In essence, better stuff for RC fans all around. Ah, then R.O.A.R. set up rules which banned sensorless setups.

Next came lipos. At first they weren't even allowed by R.O.A.R. at all. Then there was this nonsense about safety and whatnot. Finally, after they were allowed.. R.O.A.R. has recently limited the thickness of hardcase lipo packs for some idiotic reason. I am more than convinced that R.O.A.R. is biased towards keeping certain manufacturers of inferior, yet more expensive products on the market.

R.O.A.R. should be ashamed of themselves..

Sounds pretty well corrupted. I'm surprised it still exists?

Are you serious? Absolute power corrupts absolutely... ALWAYS. Just look at USA's politicians for example...

Why the 4,5mm shaft you ask? Probably so they can sell a whole new rotor with a 5mm shaft to the buyers, or a whole new set of 4,5mm pinions

I hope the LRP stuff is "da bomb"! Named dynamic 8, I think they look almost like the orions and come in 1800kv, 2200kv, and 2600kv and maybe other kv's.

they need lower kv's to get my interest, closer to 1100kv will get my attention. This is why i'm looking at tekin or castle for my next setup


Work because i gotta, play because i wanna

People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise

I never thought I would comment on O.S. engines on RCM but they are embarking on the brushless market with motors for airplanes. Who knows, they might follow up with motors for helicopters and even for cars, trucks and buggies. If they are as reliable as their glow engines, they should be very good motors.

Since OS is owned by greatplanes (Towerhobbies) I would assume the motors are rebadged something else. They already have several lines of BL motors through greatplanes companies and I would imagine that the OS line is to get the attention of the hard core nitro and gas flying people.

Funny story but a couple of years back I was at a big RC show and heard an interesting conversation. There was a single large scale electric out of about 150-200 gas/nitro large scale planes. The pilot took it up to the area where they start engines etc before moving on to the runway and taking off. He checked everything and gave a quick buzz to the props and stopped awaiting his turn. Meanwhile two other guys were making fun of him and why he wasted time with those silly electrics. They commented how he couldn't even keep it started! I really had to hold back from falling off the bench I was sitting on laughing. So when it was his turn he throttled right up, moved on to the runway, took off, and had a great flight. He was the only one who didn't have engine stalls/issues at all. I never said anything to those guys but commented about their ignorance loudly enough to my father-in-law for them to hear. They wouldn't even look at me afterward since they had made such asses out of themselves. Other people around me heard what I said as well. I wasn't rude, just politely stated that they didn't know what they were talking about and how reliable electric is.

Anyway, when I first got into lipo I knew a Heli guy who was hardcore electric and converting large scale before anyone actually made kits for electrics other than the small stuff. He told me that in 10 years (about 5 years from now) that most large scale stuff would be electric.

I can see why, when I watch the struggles of those guys getting multi engine setup going correctly (even with regular gas motors) electric is the obvious choice. Surely you don't get the same sound but the props still make a nice buzz and are loud on the the large scale stuff.

I do see a lot more of the turbines in large scale too including turbo props at the local events now. To me that is very interesting too and the seem very reliable albeit expensive.

ROAR approved Hard case lipos with reversible bullets just promotes polarity errors, and increases ROAR approved Esc purchases.

Endless supply of 3s Esc's,
Please paint me in a corner ROAR,
money grows on trees....

I always personally thought that "ROAR approved" items (motors, escs, batteries.) were limited, as in relatively limited performance and power, cause to be roar approved it has to meet a bunch of racer specifications. ROAR doesn't race 6s or anything higher than 4S (I think?), and they don't focus on power or performance as much as general racing.

Or, in other words, the motor/ESC that was ROAR approved would obviously not be much more powerful than other items that are roar approved, just slightly tweaked (settings, etc.).
