Hey guy's,I could use your help .I just placed an order for the Raptor 30V2 kit,that includes the OS-37,muffler and G4 550's.
Iam a complete newcomer to nitro's and would like to ask what all kind of accesories I'm going to require in order to get it in the air ? i.e. What Gyro/tail servo is the best to go with? Cyclic servo's? Throttle servo, is a governer required? I have a DX-7 Spektrum on the way,but I'll be using the 6100 reciever in my Trex 450SE-V2.What reciever should I purchase? Also any advise on required up-grades? I suppose that I'll need a battery and starter.Glow plug? As you can see I don't know Jack #%$@! about all the "stuff I'll need. I know that I'm asking alot but if you could help me out or let me know where i can gather the info I'd really appreciate your help
Thanks in advance

Since you are getting the DX7 transmitter, you can only get one receiver, the spektrum 7 channel, yes a 9 channel will work but you are throwing away your money for 2 channels you cannot use.

Field gear you need: starter/starter wand and battery for the starter, glow igniter, fuel pump and connector kit for your fuel bottle, volt meter for checking your receiver battery and lastly training gear (roto pod).

You also need set up tools for your heli. I would put links and prices for you via heliproz but their web site has been down for a while. I've posted this info on a thread a month or 2 ago so look through this forum and you will find all this info. Also, give the people at heliproz a call and they will set you up with everything you need. Their web site is up to the point where you can get their phone number.

Electronics, gyro/tail servo, everyone has there opinion on what is the best but what ever one you go with, get the combo where the servo comes with the gyro, Futaba 401 and JR J500T are both good gyros and are about the same as far as holding power and price, I use the Futaba 611 but that is overkill for beginners.

Servos, that again, everyone has their opinion and this question has been asked allot, so check out some of the threads here to help make a choice. The servos I put in my most recent heli are $110 each (JR8717), overkill for a beginner and decent servos can be got for less than $30 each.

Governor, also, check some of the threads in this forum, no they are not needed and for a beginner are not recommended.

Sorry if I sound short but all of your questions have been asked and thoroughly answered fairly recently in this forum. There is a wealth of info here, take a look.

A few of things to think about. A couple of my options are different than vandelescrow's by my personal preferance. The rest I agree with him about.

- Do you have a lipo charger? If so, I would highly reccomend an Align 2 in 1 regulator (B6T) (http://grandrc.com/inc/sdetail/102751) and something like a Thunder Power 3400mah 2s Rx LiPo (http://grandrc.com/inc/sdetail/60058). Going this route gives you two bonuses.
1) Longer time between Rx battery charges. Depending on your servos, you'd probably make at least 6 flights between charges.
2) Eliminates the need for a glow plug driver and remote glowplug connector. Less crap to carry around when you are starting your heli. Push the button and crank it over.
Even if you don't have a lipo charger, for a 2S receiver battery you don't need anything expensive or flashy, a little charger and balancer will do the deed. I strongly recommend this. If you go this route, note that you will be running a 6V system, not 4.8, so you will need to put something like this 5.1V regualtor (http://grandrc.com/inc/sdetail/60060) between your gyro and tail rotor servo in most cases.

- Do you own a cordless drill? If so you can drop the electric starter and starter battery and just buy the hex shaft. Take the coupler of the end and use your cordless drill.

- By a manual fuel pump of the type that hooks right on to your fuel bottle or can. One less thing you need to power.

If you do all this, your trip to the field to fly can will only include your heli, fuel can, radio, and an electric drill. Less crap to carry around is always good. Going to the flight line to start will also be less things to juggle. No flight box with battery for the starter, no glow driver. Just put the heli and radio down, and crank the heli over with a drill. No muss, no fuss.

A lot of this fits into "things I wished I had done in the first place".

- Servos: I like these Hitec 5625's (http://www.amainhobbies.com/product_info.php/products_id/18373) myself. I put them in my Titan. They may be a little much for the 30, but the price is decent and they are a fast, strong servo. The analog version the 625 (http://www.amainhobbies.com/product_info.php/cPath/2_384_395/products_id/4780) would probably do nicely for a 30 and are $20 cheaper. I'm sure you'll get other opinions.

-Governor: Don't buy one until after you have the engine well tuned and broken in. You can destroy a poorly tuned engine with a governor. That said, when/if you decide you want one, the multigov is probably the best on the market right now. No funky calculations to do, no weird radio setup, just program the speeds you want right into the thing and off you go. On the note of headspeed, a tach of some sort is great. Do you know anyone who has an optical one? They are expensive, but knowing what your headpseed is makes it worth it. The other option is a normal airplane tach jury rigged to your tail boom while you hover, crude but it works. Check out the heli master (http://grandrc.com/inc/sdetail/66875) it has an optical tach, a temperature sensor (also good to know how hot your engine is), a servo tester, wattmeter, and battery checker a nice all-in one unit for a good price.

The cordless drill is a great idea, easily recharged when needed. I know a few people who use them. Make sure it is a "drill" and not an electric screw driver. You need the speed to start the engine. Also if it is a reversable, make sure it turns the right way. You may want to put a sticker or something on the drill just in case the wife uses it, Oops, I'm sorry, wife use power tools? If I have my directions right, it needs to turn counter clockwise or "reverse" on the drill.

I use cordless drill on my 60. I too like the align 2 in 1. I still need the tach. Also cheep tooth brushes for cleaning. They get in the hard to reach spots. They call nitros slimmers for a reason.

Here is my setup for my Raptor 30v2...and it flies great!

OS 37
DS821 on Aileron and elevator
8717 on collective ... found the 821 either too slow or weak to change pitch of the blades fast enough when doing flips or tic tocs.
401 Gyro with 9254.
Running 2 2100 7.4 Thunder Power Lites on the align regulator and get right at 10-11 flights per charge and have never put back more than 1500 in either pack.

I have changed mine a bit though ... added the 50 boom and Radix 600 blades and it flies better even with the OS 37 than with mah 550's. I was worried the OS37 might not swing the bigger blades but the heli is more responsive now. Probably going to upgrade to OS50, 8.5 gears and go with 8717's to replace the 821's shortly but that's what's great about this heli...lots of options!

The DS821's will work ok for a first time flier, i have them in my 30V2, i wouldn't try any hard 3d with them but for hovering, forward flight, and also for mild 3d (loops, rolls and such high off the ground). i like the GY401/9254 combo. if you want a good 12v starter/field battery and charger lemme know i have one laying around that ill let go as a set for a reasonable price, PM me if your interested:thumbup:

Unless you're planning on doing 3D next week at a competition level, don't bother looking at JR8717 servos. They are serious overkill for a 30 sized heli and you can spend the $50 you save per servo on something else. My opinion anyhow.

I would disagree with with you only in that the 8717 will in fact make a big difference for anyone on the 30V2 as compared to the DS 821 on the Collective Servo. Doing stationary flips I was chasing the flip with the 821 on collective. With the 8717 on Collective the heli responded to collective input with much more authority and faster. I had probably 50 flights on the bird before the 8717 and now another 100 after and there is no comparision. For hovering and general sport flying though you are correct...no difference.

Tic Tocs and mild piro flips work too! Have to make sure not to bog the head though...an OS 37 only goes so far! :)
