One reason "may" be that there are a whole lotta people who got into helis with those micro contra rotating thingamajigs, who then moved on to 450 size helis & other electrics. Most realize that you need fligt time in order to get better at flying. More flight time = more relaxed flying & taking your time to learn. I know that when I fly my electrics I feel like I gotta get my moves in early or Imma run outta battery
Ad to that the "percieved" issues with parts cost/count/availability from other gasser suppliers & you can start to see why it would be appealing to the masses. If Align gets it right I believe you'll see one in every one's stable just like the raptors used to be. Everyone made fun of them but everyone had one.
I can see a potential business opportunity for someone already. The "break in period" seems to be one of the bigger issues with gasser engines as they tend to vibrate & run roughly & are hard on the electronics until they are properly broken in. If someone were to open a business of either selling motors that are already broken in or offering to do it in a timely basis, they could take advantage of the situation to make some money while alleviating the hassle of breaking in a motor for the rest of us. I envision someones garage with 10 or so wooden test stands with a bunch of gasser motors fired & running in while the neighbors are having a BBQ

Well I can see why you can't do 3d with them...at least real 3d(nothing like opening up a can of worms Rich), the lack of power will stop you from doing hard 3d. I take it that you fellas are running different gear ratios than the nitro guys?

you are sadly misinformed here my friend in the right hands a gasser can rock. as for lack of power again misinformed a Hanson 3D max 26puh gas engine makes 4.8hp at 13000 rpm in other words no bogging.

do a little more research you might be surprised.
the reality is that most of us that fly Gasser's are not skilled enough to really do super hard 3D and guys like you are so sure about nitro power that you wont even try it.

And the real truth is that a high power electric are the fastest and most powerful.

Like I said give one a try I think you will change your tune.

If align comes with a gasser I probably would not get one I really like the Spectra g & Bergen gas helis very high quality. But it will open a lot of doors for people who have outdated thinking about gassers.

i have had three gassers one crash knocks out the fuel savings there expensive to buy and fix when they go in they go in hard because of there weight. i have had different makes there simply do not compete with nitro there just to heavy yes they will fly for 30 mins on a tank and lots of power but i was never 100 percent happy with how they fly 3ding one is harder work all round they are much harder to get setup well chasing vibes etc. i find them more noisy when on song even with hatori pipe and for me the smell of petrol in the car to and from field and indoors when working and storing them to much.

Tale,
If you are telling me that some of these engines are turning 13,000 rpm, then what head speed are you guys running? You would have to be running in the 8:50 range to be at any kind of head speed to do some of the maneuvers that 3d demands, mabey even less.

8.5 @ 13000 would be about 1530

STOC/most commen gear ratio( or mine ) 7.15 @ 13,000 works out to about 1820 HS
I have my GV-1 set at 1850 for head speed 13200rpm and it has no bog power at full climb out. +10 -10 on pitch & 710 blades.

On the spectra g there are many gear ratio options. 6.5 for 2000 HS @ 13000. The Hanson 3D max and other good 26 puh zenoah engines can turn more than 13000rpm that's just were Hanson rates max HP on the 3D max. I was very impressed by how well a big bird can 3D but its not a trex 700 nitro It can do all the tricks just slower but with plenty of power. It does not crack move although I cant crack move anyhow

Its good for 710, and 720s which is what most here run...Most don't have the drive train to hang on to it though....the Predator system is way ahead in this department...

well at 7.5 ratio and turning 1850 rpm and no bog. I find it hard to believe that a gas engine can keep up that kind of pace.trex 700fbl cal30,minititan,, trx600fbl,trex250,logo 500,Velocity N2

why is it hard to believe?
Yeah their heavier than nitro, but almost twice the capacity, so much more torque on tap.
A modded engine is much better than stock anway.
My gasser has 7.38 ratio, 1850 HS, and it hauls ass

What I tell folks who keep on putting this BS out is: ok, it has enough power I could strap on your heli to mine, and still do all the maneuvers, understand the power now? Can your nitro do this?

I hope Align makes the 700G (or 750G, whatever they'll call it). I have a Predator that Billme has helped me with. I have not done to much with it this summer as other priorities have come before my heli's (bought an RV, family time) so I have been sticking with my Nitro 50's BUT I can tell you that the 5 gallons I flew through my Predator last year left me with a good, positive impression on gassers.

Last year I flew it with the stock gear ratio of 6.28. My first few gallons I ran the head speed at ~1650 and it was good flying. The last few I ran it up to about 1900 headspeed and the heli really came to life. It has LOTS of power. I wrecked it doing some continuous flips across the flying field and got mesmerized, locked up mentally and pushed the collective the wrong way.

I've put it back together with the 14T pinion making it a gear ratio of 6.72. I have a few tanks through this and the gear ratio is the right one for flying more aggressive acrobatics.

Anyway, I'm not a hot shot pilot but here is a video of my flying the Predator at about 1700 RPM on the head. Still pretty maneuverable if you ask me and it does get better at 1900. I can't compare it to a 90 since I haven't owned one yet but this is pretty good to me. You do feel the extra weight but it's not really that bad, it auto's great!

This is the standard Hanson engine that Century will bundle with the Predator, not the 3D Max. Hanson does a great job building them and my vibrations have never been any worse than any 90 I've seen. The trick I think is to get the clutch on straight.

They are not for everyone and I still intend on getting a slimer-90 some day but you may have to try a properly setup gasser before completely passing on them.

It's the power to weight ratio that puts me off honestly. For now there is no easy way to overcome that.

before making a statement like this you should fly one.

A Hanson or Toxic modded zenoah 26puh like the 3d-max are rated at 4.8 hp @ 13,000 RPM far more than the best 90 nitro and way more torque.

they do weigh more than a 90 nitro so they aren't as quick but they are more powerful and the torque will keep the Head Speed up very well.

some of the custom built gas engines being tested by some members here are making even more power.

and as Billme said you could hang a 700 nitro from the skids and still pull continuous loops

Its not going to replace your 90 nitro but at $3 a gal vs $30 a gal and triple the runtime per gal and no cleanup what more can be said

Ok, how about you let us know what an average Gasser weighs and then we can get some hard figures on Power to Weight for comparison?

The ratio is too steep, you do a heck of job to do that..Its not easy at that ratio..6.7 at 1800 is a site to see if you love gassers...

You got to really learn helicopter dynamics to be good at gassers.

You must learn to fly them and learn to use the weight to your advantage..Most stick bangers fade away quick, but to those who know how to appreciate a good wine, you will love them...
