Hello. My name is Matt and I'm addicted to heili's! I've been a member here for a little over a year and have mainly flown electric 450's (Esky Belt Cps, they rock!!).

I have recently been given the O.K. by my wife to purchase a nitro heli, so, after a little research online, I decided to go with the Raptor 30 v2. The UPS guy just dropped off my latest addition to the hangar and It looks awesome!!!

I have experience setting up and flying foamies, planks and electric heli's but this is my first nitro heli. I know that this forum provides a wealth of info for anyone willing to ask so here goes...

1) I have the DX7 Tx and the heli is equipped with the AR7000. What is the recommended throttle curve for your basic hover and FF? I have downloaded the manual online and there are suggestions there. Are these O.K. to use for the DX7 or has someone found something better that works?

2) My rappy doesn't have a header tank. How important is to have one and where should I look if I want to order one?

3) I have the OS 37SZ. What type of fuel is recommended for this motor? I have been on the Tower Hobbies website where they sell this motor and they don't say what type of fuel to use (just that 15%-30% nitro is recommended). Should I use after-run oil

I'll stop there for now. Thanks to all in advance for your help and Merry Christmas!!

Matt

http://www.raptortechnique.com has most of those answers and some that you haven't asked yet.

Just run a heli fuel and you will be fine, I'd run 20 or 30 percent cool power heli or magnum heli fuel.

Check out these sites - lots of good reading (BH beat me to this as I was typing!)

1. Depends on so many things such as pitch curve, engine choice, exhaust, altitude, ect.. It'll much different than your electric though so don't use that as a basis. The idea here is to set it up so that the engine and blade RPM don't vary. It'll apply the right amount of throttle needed to maintain RPM without over-revving. Look into cyclic-throttle mixing.

2. Not important. Very important to make sure your clunk line reaches the top of the tank when it's upside down.

3. I run 15% nitro almost exclusively, but 30% is easier to tune. It's a great long debate here 15% or 30%. 15% = cheaper fuel and runs longer on a tank of fuel but is harder to tune. 30% is more expensive and you'll use it faster but makes a bit more power and is easier to tune.

Just an FYI on the header tank. An often overlooked feature of the header, is that it will give a small warning if your main clunk line craps out. On 2 occasions I was able to land after noticing the header was emptying while the main was still half full. Granted you only get about 2-3 minutes of warning if this happens, but its better than flaming out while inverted.

You may need to retune if you add a header after the initial tune.

+2 on the header.

Be aware that the throttle curve in idle up for a nitro will be somewhat different to that for an electric; you don't want to go running 100% everywhere, unless you like watching the rotorhead and blades explode You'll have a more pronounced V-curve, assuming you want the heli set up for equal negative and positive collective pitch. Around mid stick (0 degrees collective) you'll have a lot less than 100% throttle - raptortechnique will have this covered.
Using a governor makes the throttle curve irrelevant... UNTIL the governor craps out in flight

How important is it to run a governor?

Depends on how you're flying. Anytime you're really loading and unloading the head they are great, if you're just buzzing around, they make things easier but it's definately something you can live without.

TD, when is the last time you've had a governor crap out in flight?

I've never had a governor crap out....because I've never had a governor I assume that they're a pretty reliable piece of kit.

In a round about way I was encouraging mprice to get a throttle curve working and understand it before thinking about a governor.

i agree that its good to learn about throttle curves and not just slap a gov on there.

i run a 100-85-55-85-100 idle up curve on my 30v2. it has a OS 32 with a mavrikk muffler. no overspeeding at all and fairly agile.
With your 37 i would start with 100-65-45-65-100. you can adjust it after break in and fine tune for style later. for normal i would start at 0-30-50-75-100.

I would use the header tank. (just how i do it but others may say differently)

I dont use after run oil and i use 30% fuel. The higher nitro will make it easier for you to learn to tune the engine (as well as more power). i dont use after run oil because i cant get to the carb or else i would. I DEFINATLY run the engine dry at the end of the day.
You will like your 30v2.
Just my .02

Thanks for all the great advice!! I'm getting close to hovering this baby

I went ahead and ordered a header tank (K&S....looked about as good as any).

I searched on raptortechnique.com and found a little info on balancing the heli. It suggests filling up the fuel tank 1/2 full and holding the heli by the main blade grips with the nose and tail parallel with the ground. I know they're different, but I have always checked my electrics by picking the heli up by the flybar.

What method do you guys recommend?

Also, what type of on-board battery monitor (if any) do you guys use? I always check my battery prior to flying, I just like to use the battery monitor for peace-of-mind.

Thanks again for your input!

the on board "meter style" are not really needed as long as you are load testine before each flight. After you get used to your helicopter you will figure out how many flights you can safely get from a charge. Still a good idea to check regularly though.

I am using a 3S 2100mqh lipo on a CC10BEC you have 450's you got this stuff lying around. I just top it off before I go to fly no monitor necessary the RX pack lasts longer than the TX.

As far as the setup I did mine by the book and all is well got a gallon through it before winter Thats a lot of 15% nitro in the os32.

Good luck with the rappy 30 I just went it my own like you after a year of electrics. The BCPP, King2, Trex450SEV1 and now my favorite the raptor 30. And back to a firefox100.

No Really I am the club President!!!
