Spectra-G
Sean,

I couldn't agree more with all the statements from the Spectra-G owners that have commented on your posting. There are always going to be opinions about nearly everything in this hobby but at the end of the day it is simply a matter of what you want. Trust me, there are a TON of good people with far far more experience on helis of all sorts that contribute to the RunRyder experience. This is especially true of a lot of the Spectra-G owners as well. The gasser market seems to have its own little (acually big) community. Sort through the comments as you see fit and you will be in great shape!

Too too purchased a used Spectra a few years back and, just as Carey suggested, I went through it very thoroughly. It was advertised as having "about" 2 gallons through it but upon receipt that was to the contrary. Anway, mine started off life as a Toxic 231 that had issues from the previous owner. Incredible vibration, tail shakes, engine tuning, etc. From there the teardown began.

Fast forward to today and with the help of all the MA folks both here and in Montana, Raja (rbort), Toxic Al, Hanson motors, on and on I now have a really nice running machine. Gassers are definitely different than nitros that is for sure. Engine tuning is still my weakest asset but that is where you have to trust the experts. And if you ever get the chance to go to IRCHA...well, enough said!

My Spectra is now outfitted with 9252s on cyclic, Spartan/BLS251 on T/R, can't remember throttle, G260 Super (Hanson modified), Zimmerman side mount, GV1, Jewel generator (love it), Tempest 3D head (love it), MAH 710/105, enclosed T/R, etc.

It flies incredibly well and for me, not being a 3D guy, the economy of it is just fantastic. I can go to the field with my gallon of gas, heli, and transmitter and pretty much fly all day if I wasn't married. The Jewel keeps my flight pack charged and the fuel lasts a long time, even at 15 minutes/flight.

Anyway, I could go on and on. Bottom line, MA makes a very nice product. Jrock's comments are spot on the money as well. Couldn't have said it better. I have an Extreme and Stratus so familiarity with the quality and construction is second to none (IMO). Keep us posted on your status and let us know how things are going. Give us a few pics if you can as well.

Thanks

Nick

P.S. One thing I am curious about are any plans on behalf of MA to release a new or upgraded version of the Spectra-G. Not a requirement, just more of a curiosity.

Thanks for all the great input guys!

Well I just got back from the post office. I shipped the engine back to Al for a rebuild, and the clutch assm. to MA to replace the liner and the carrier bearing. Hopefully it won't be too expensive.

I was looking into perhaps replacing my GY401/9254 with something better as I've heard from a couple of people that the 9254 doesn't handle the vibes of a gasser very well. Does have any experience with this?

Thanks,
Sean

Sean,

You will really like working with Toxic Al. Do a search for him on RR using that same name. I spoke with him quite often when he was rebuilding my engine (as a 231) and during the break-in period. Great guy to work with!

On the gyro front I was running a GY611/9256 combo which worked really well. That is the only gyro I ran up to the point of trying a Spartan/BLS251 set up. The only reason for the Spartan/BLS is personal preference. I had read a ton about the Spartan both with a 251 and with numerous other servos. The reviews have been great and I simply wanted to try one out. Otherwise, the 611/9256 worked great. I think you will find a few guys did or are still running the 401/9254. I will let them comment accordingly.

Good luck!

Nick

Yeah CitationX, I spoke with Al on several occasions and he seems like a nice guy.

I don't want this to start a crap show, but why does Al only suggest the G231 for the Spectra when other modifiers offer the G26? Personally I don't really care which motor I have as I'm sure both are more than what I need as a relatively novice flier, I'm just curious.

Thanks,
Sean

I'm sure this will come after they release the new 90, but that might not happen for another year.

I'd love to see a 50 size gasser. Something to dust the Radikal. Long term, I'll be getting one and I'd rather it be MA. I just like that size better for hauling around

Thats true. Even though the difference in length isn't all that much, the Spectra just seems much larger than the radikal. Well to me anyway.

this recommendation has nothing to do with TRM. The manufacturer doesn't recommend the G26 or larger motors in this model.

The gear ratio on the Spectra was designed to use the G231 and lets the motor turn up where it makes the best power. The larger motors don't like those RPM ranges and can vibrate significantly if improperly configured.

IF the motor is very well balanced and IF you know how to tune it and IF you assemble the model careful and pay attention to what its telling you when its operating, then you could have success with a motor larger than the 231 (See Raja as an example). Unfortunately sometimes folks who are just learning how to run gasoline motors want to try this and can just compound the problems by having the motor out of tune.

TRM has 26 and 29 motors, they work. I would not put them in the Spectra unless you change the gear ratio. For that matter I wouldn't put any of these larger motors in ANY model that has a GR higher than about 6.4:1.

With the 14T pinion eventually coming out for the Spectra, that will give a 6.57:1 ratio which is better for the larger engines.

well, if you also switch the main gear to a 90 tooth, you can get back to 6.42:1

Thanks for the response. As I said, I'm not interested in using a larger motor, I was just curious as to why there seemed to be conflicting information in regards to the choice of engine. Thanks for the clarification Carey Shurley

Welcome to the Spectra Sean
Not for nothing but I found that the 6.92 GR works better than the 6.43 GR in my 1005. Granted I don't fly ballistic head speeds, (1550 to 1800max) but with a 6.43 at the same speeds with a G26 motor I find it bogs easier than at 6.92.

Cool thanks. That's the gear ratio that I plan on using. Will 710's be ok with the TRM g231 and that ratio?

Thanks,
Sean

Thanks [X]Outlaw! Yeah, I'm already amazed at the build quality, now I just can't wait to get it in the air. Maybe sometime in the next few weeks.

Got the engine back from toxic Monday, and the clutch back from MA. My jewel mount is in transit. The build begins! Check my gallery for photos. I'll update it as I progress with the build.

Hurrry up and build it!
I just flew mine today first time this year since I got back from Jamaica and really enjoyed it - almost forgot how well this thing flies! Much better than that 450 I've been flying in Jamaica and indoors here...

I'm trying, I'm trying! Just waiting on the COUPLER AND MOUNT! No, really its tough trying to juggle this addiction and school. Hopefully in the next week or so I'll have it built and be able to start breaking-in the engine. I can't wait! Then again, I can't really do anything until the snow clears. We are supposed to get another 10 to 14 inches tonight into tomorrow. Not bitching about the weather Raja, just stating the facts.
