My new Spectra G arrived today (questions)

[paulw1283]

I'll be building my spectra G soon. Are there any good guide on building this model? A walk through would be nice. I'm especially interested in knowing which areas deserves attention.

I got the Futaba 9CHP radio/receiver with 4 9252 servos. I'm ordering a Gy611 Gyro too.

1.Which engine should I get? I heard the Zenoah 231 modified is pretty good. Any place stock them or have a good price?

2. What blade combinations is the best? I'm thinking 710mm main blade and 105 mm tail. But I don't know which brand is the best. Please tell me, and also where to order them.

3. What about mufflers? I heard the Hatori pipe is nice but it has a tendency to fall off. What should I do?

4. What type of engine oil should I use and what is the best mixture ratio? At my local Wal Mart they got the 2 cycle oil for lawnmowers and chainsaws, can that work?

What other miscellaneous stuff do I need to operate my gasser?

Thanks for the help.

Hi,

Like you, i just got a Spectra-G.

John Garst (Bigcr) made an excellent build video on a Spectra-G with plenty of great tips. Just do a search here and you should be able to find it. It's pretty big at around 400Mb.

Also, download the Spectra-G users guide from MA which has some reccemendations on setup and oil usage.

The Zenoah 231PUH is very good, the TRM modified motor is even better. Try Rick's as i believe they stock both.

710 mains and 105 tails is correct. You get some 105mm plastic tail blades with the kit. Blades are a personal preference choice as each brand will have a different "feel". I went with the Radix blades at both ends.

The early Hatori's did get loose often. The latest Hatori pipe (#957) has a stainless steel adapter plate that suposedly fixes the issue.
Some people also use the Century Torpedo V2 pipe with good results.

You radio, servos and Gyro are a great match for the heli.

Recemmended oil is a mineral based two-stroke oil for the first gallon and a good quality Synthetic for the rest of the engines life.

All the info you need can be found here in these forums.

I tried searching for those videos but can't find them. Can anyone point out the link?

thanks

Look for Spectra Build. There are really two, part 1 and part 2. However, if you want them in smaller chunks, the part 1 is broken down into 5 chunks, as is the part 2.

John's video was highly helpful for mine.

I searched Rick's for the TRM modified 231 engine but can't find it. They only have this one here:

I'd appreciate it if someone can tell me where I can purchase a Zenoah 231 TRM engine.

BTW, do you guys sand off that seam that runs down the middle of the canopy? I'd like to paint it a nice professional finish. How much does it cost if I send it some where? thanks

The modified 231's come directly from MA or you can send your new 231 to have it modded.
