Hey guys,

I just bought my first Miniature Aircraft. About three weeks ago I decided that I really wanted a gasser. After researching the various models available I decided on a Spectra-G, unfortunately I couldn't find anything within my price range and settled on the Century Radikal. After owning it for about two weeks, a deal came around on a Spectra that I couldn't refuse. I sold the Radikal and just picked the Spectra-G up today. I have to admit, at first I was a little hesitant on the decision. After seeing the Spectra in person, instantly I lost all apprehension of my choice. Don't get me wrong, the Radikal is a great machine, but in my eyes, there is little to no comparison in terms of build quality between the two. This thing is built like a tank. The engineering is awesome. The fit and finish is one of the best I have ever seen. Its little things like the threaded bolts pressed into the frame for the servos. Ohh, and zero play in the head among other things.

I look forward to talking with all of you, as I am sure that I will have lots of questions in the future, and perhaps I can contribute to some of you with knowledge I have learned from other helis.

Thanks,
Sean

welcome aboard, its a well made helicopter

I'm assuming you bought it assembled and flying. Unless you absolutely know for a fact its never been crashed, you might want to look it over very carefully.

some folks fix them back up just like new, and some folks cut a lot of corners that result in setup and flying issues.

From I was told, it has not ever been crashed. The gentleman that I bought it from seems very honest. That being said, I've looked over it and there is no evidence to suggest otherwise, not even a scratch. Regardless, I will disassemble it over the next few weeks and go over it with a fine toothed comb just because I like to build, and it will help me understand the mechanics better.

Are there any design issues that I should be aware of?

Thanks,
Sean

what motor and size is installed in it (stock or modified)?

what muffler is on it?

which rotor head is on it (extreme or tempest)?

engine installed backwards or forwards?

air filter?

size and make of main/tail rotor blades?

No horaico, it isn't that one although I had my eye on it and it sold before I could do anything.

As for the motor, its a toxic G231puh. The issue is that it had a hot start on its first start and fried the sleeve, ring, piston and clutch. So I am sending back to toxic for a rebuild early this week. I spoke to them last week and it shouldn't be an issue. It has a V4 muffler on it I believe. It's an extreme head. Has an air filter. Has SAB 710 red devils, and SAB tail blades. As for the engine, it is facing rearward.

What is the difference in the engine placement?

Thanks,
Sean

just trying to understand what you have.

has the clutch and liner been replaced?

is the t/r transmission a closed case or an open case (exposed gears)?

things to look out for:
  1. use hi-temp rtv to seal the muffler/bolts
  2. consider getting another throttle mount plate and glue the two together. It stiffens up the throttle mount.
  3. either glue the tail boom into the front boom mounts, put a screw through the frame, or wrap it with some tape. If vibration is bad the tail boom can turn
  4. if it has the open t/r box, make sure the gear mesh stays tight.
  5. when you pull the motor, check the "uni-ball" on the clutch driver to make sure its okay and tight. Also check the rubber dampers in the fan to make sure they are okay.

Hey Carey Shurley,

I was just asking about the engine placement out of curiosity. Was there a redesign?

In regards to the transmission, it is a closed tail.
The clutch has not been replaced, I was planning on doing that.

Thank you for the tips!

transmission - make sure there isn't any play, it turns smoothly and it has some grease in it.

engine - no, the kit is designed to let you run the motor facing either direction.

If you run it backwards, the model has a more neutral CG and you'll need to run the tank in the front

if you run it forward (other mfgrs have caught on that this is a good idea) you can run the tank behind the motor and the model has a slightly forward CG.

you have to adjust the canopy cutouts depending on which way its turned.

Mike545 is right. An MA is the the best helicopter. If its assembled right and treated well it will almost last forever. Mine is very old and I only have changed the clutch liner and the dampeners in the rotorhead. You can allmost "park them in the air". So sturdy..

Sean,

I too got the gasser bug and purchased a pair of Spectra G kits. The assembly process (although not what I was use to) was very straight forward. The fit and finish of the kits were exactly what you'd expect from MA. You'll really like TRM's engine I have one in mine. I'm presently almost completed the breakin process and this thing is beginning to show some power.

Don't get me wrong, the Radikal is a great machine, but in my eyes, there is little to no comparison in terms of build quality between the two.
I'll second that! In my ownership I haven't had to do much of anything to my purchased used and RTF Spectra G other than put fuel in it and fly. The Radikal on the other hand illustrates the difference between a truly well designed and manufactured heli like the Spectra and an average heli with so-so manufacturing quality, here's a good example of what I'm talking about... https://rc.runryder.com/t565201p1/

That said, the Radikal is huge fun to fly and I do enjoy both it and the Spectra, but the Spectra will still be flying long after the Radikal has seen it's last flight.

Some obsolete nitro helis too...

WOW, little stuff like that just further reassures me that I made the right decision. I would think that it would be so simple to account for the space needed on the tappered head of the screw, but I guess the enigneers missed that.

Everything aside, it is a cool concept and has loads of potential. Maybe MA will take note and one-up Century... That I'd buy.

You know what is really nice about the Spectra and Miniature Aircraft in general? The fact that you have an American made heli with a manufacturing/design team who speaks English and will work with you to get the parts/upgrades you want.

Try calling up Align and asking for a custom engine mount? It's not going to happen. But with MA, if you're willing to wait and pay extra, they'll work with you to make your heli everything you want it to be. In addition, parts from many of the helis are pretty much interchangeable. While this certainly adds to the complexity of the bird, the fact is you can mix and match components to get the design just how you want--like Legos. For example, I recently bought some of the Tuff Strut I landing gear. Now my Spectra sits up higher which I like. I also designed some ball link traps using all stock MA parts. Pretty neat if you ask me.

My Align helicopters are about 70% aftermarket parts, but my MA heli is 100% MA parts. What this means is that there is no other manufacturer who makes higher quality parts.

Back in the day before my long hiatus, all I owned was MA at the end. Simply the best IMO. You will NOT be sorry with your purchase.

My father and I both bought Spectra G's last year and we absolutely love them. They are incredible machines. My dad actually just picked up a radikal last week. Looks like one incredible bird.

It's a complex, costly, glow powered anti-gravity machine!
