I've had T-Rex 600n for 5 years . It is not tail heavy and been one of my favorite helicopters . I've never heard of anyone of my friends that have trex 600n be tail heavy.

same here half a tank of fuel. I also c.g mine by removing the head button and replace with a bolt and thick string then hang it from the ceiling.

Mine is not DFC I used parts from 600E " blade grips" to make my own head with a Century swash follower.

FARRL do you have any pics of your heli? I would like to see what is different about your set up?

Is he a newbie? If so, why would you reccomend a nitro? More cost and more work and more repair only to discourage the learning process on top of the steep learning curve which is much higher for newbies. Get him a small 450 or 500 electric, read and learn the the basics of setting up, orientations, then do the same for upside down. After that, he can do nitros. Practice new maneuvers on the small electrics and have fun with more confidence on the bigger nitros or electrics. Just my one million cents, plus the savings this could save him, so repay me whenever you can

With that said, I can understand his love for nitro because I still love nitro, the sound, the quick refill and go, the smoke, and the power when you geat near empty And don't forget, it's all about thumbs and not just power.

LOL I resent that I started with a 30 nitro back in 2006 the only regret I have was buying a century, I'm very happy with Align
it's not more to learn nitro but actually less than electric
with nitro you don't worry about OHMs law or have to learn about c rating and charging rates or about what KV motor you need for the gear ratio you have and what HS you want to fly or how to make your set-up efficient.

with nitro you fill the tank, start it and hover till you learn your orientations, by then the engine is almost broken in and ready for tuning, tuning is about the only hard part to nitro after that's learned.

I grew up with nitro from when I was 7 yrs old.
So nitro was easy for me. Much easyer than the elec I am learning now . Some people can't start a truck with a manual choke let alone know what rich and lean describe for an internal combustion engine . But I definitely think it all depends on each individual's background and mechanical ability

true it is not the absolute best method but it works well for balance of c.g. a bit more accurate than holding the heli sideways by the main.

Too much damping from pendulum effect to accurately set cg. Compare to pivoting on mainshaft and you'll sometimes see a major discrepancy.

I'm confused, this CG sidebar conversation appears to promote both balancing methods as superior?

Which is it?

Don,

Yeah, too much weight hanging below masks less-than-major CG errors.

Aaron,

I've seen many a model that would hang more or less level but would also drop obviously nose or tail heavy when the mainshaft was the pivot point with the model up on its side. This method is more sensitive to true CG errors. Those with electric models need to pay attention to motor cogging and check in both orientations (flip the model around 180 D about the axis of rotation) so you don't mask a problem or pull the motor away from the maingear.

Ben Minor

NB: Close isn't close enough for optimum performance with FBL controllers. Even the very best ones will not piro as flat with poor CG due to its effects on piro comp.

OK that's what I thought. I do it that way with a little more than half a tank. No one flies to the last drop.

Fascinating discussion. I had never thought of how the offset in the center of mass would affect balance, if only looking at it by hanging from the grips.Rob

I suppose we differ in our approach to training new pilots. Why whould you steer a new pilot in another direction than what they want to learn? If they want to learn nitro, then teach them nitro I say and if they want E then sure, I will bring them up on E.

There's no such thing as too steep a learning curve when you have ginuine interest in a specific segement of the hobby like nitro. You sound like you learned on E. Which is fine, but how would you feel if you came to me asking how to get into E and I told you no, get a nitro because that's what I came up on? Sure, I can come up with all the reasons why N is better, but in the end, that's not my decision to make. If in the end, you change your mind, then by all means....go for it.

I believe if you nurture their particular interests, they are more likely to succeed regardless of the output source. I learned on nitro by myself with no problems. Just set the engine to factory and go. Tune in as needed. Today's engines are just that good. And there in no way E is less expensive than nitro. Chargers, boards, adapters, power supplies, and yep....batteries. Just with that, you are looking at at least $600 vs. buying and engine, a pipe, and a gallon of fuel to start out with.
Get him a small 450 or 500 electric
I might recommend a 500 for a new guy who intends to stay in the hobby for a little while and enjoys E helis. I would never recommend a 450 or below for anyone seriously looking to stay in the hobby. They are just too finnicky and too squirely. I might recommend a 450 to a new guy who just wants a toy to play with until it breaks and has no real intention to stick around long.

Just a couple of cents from Mellisa though.

Mandatory. I don't care who thinks training gear is best. They are wrong.
