Hey guys,
I've been thinking about getting a gasser Heli for a while now, but so far after reading thread after thread and watching video after video, they all require some sort of modification to fly rite.
Is there a particular brand of Heli and 3d engine that works like it should without having to do any modifications?
Thanks in advance!

The Whiplash Gasser with a Zenoah engine is your best bet. The gasser man to chat with here is rbort. Raja is extremely helpful and has answered many of my gasser questions. He's pretty good with Autos too.

I think Nycatt has given you the best combination! Let us know what you decide on and how you like it!

Thanks!
Thanks for the input guys, but I was watching a video that Carey Shurely( that may not be spelled rite) made about some upgrades for the whiplash. I just don't want to buy a money pit. The main reason I'm thinking about gas is to save money.

the upgrades I was showing for the Whiplash have either been incorporated into the kit or are just options

The model performs very well out of the box. It will perform better if you match the gear ratio, engine, exhaust system and blades for the type of flying you want to do.

Whiplash
I fly 3d or I try. I currently fly trex550 and trex700e. I know that it won't have quite as much power as I'm used to, but I'm ok with that. My thinking is that it will give me longer flight times which equals more practice at a lower price. Plus it will force me to get better at collective management. Can u recommend a setup(motor, pipe, gear ratio etc....) that will work for what I'm trying to accomplish?
Ps I'm glad to hear a good recommendation is the whiplash, because I've always wanted to get a Miniature Aircraft bird!

Thanks!
Brad

as always with gas powered helicopters you'll get several opinions either publicly or via PM telling you that whatever is written here is wrong and you should really use......"fill in the blanks" to get the best performance. Thats just part of the world of gas helicopters.

I'll give you some options that you can chose from and then you can make up your own mind. The important thing is to match the parts

rotor head

the FBL version will have better performance as you don't have the drag from the flybar

available gear ratios
  1. 6.88 - stock ratio
  2. 7.29 - optional ratio
engine
there are three on the market that have some track record in no particular order
  1. TRM 270TT - high rpm - use with the 7.29 ratio
  2. BH Hanson 29 3D Max - use with the 6.88 ratio
  3. HWC RCE G29 3D Extreme - use with the 6.88 ratio - this is an EI based engine and will require a larger battery for long flight times
exhaust system
here are some options
  1. Hatori SB12 - highest performance with the TRM engines. Its expensive but very high quality
  2. Century Torpedo slim - seems to work well with the Hanson and HWC motors. Its a bit loud but very lightweight and mid priced
  3. RJX gas muffler - second in performance with the TRM engines. Least expensive but has questionable quality. Some are fine and some aren't. Its the heaviest of the mufflers
  4. Hanson tuned pipe system - best power with the Hanson engine. It will bolt right onto the whiplash. Its sound is loud and raspy.
  5. Quickdraw pipe - best power with the TRM engine. There is a configuration for the Whiplash. Its sound is also loud and raspy.
rotor blades

you'll have to experiment with blades to find which ones you like but in general terms

with the 7.29 ratio run 700's
with the 6.88 ratio run 690's

generators

not required but can be useful for long flight times with small/lightweight batteries

two out there
  1. Jewel - long track record but you'll lose the option of spin starting. It requires adding some mechanical parts.
  2. Powerbug - relatively new, fits inside the fan housing, utilizes the existing magneto magnets and allows both spin and pull starting
expect a number of other opinons, the good thing is that all of these things will work, the differences in performance are often quite small between the combinations or components. The exceptions are the tuned pipes, properly tuned with the proper matching engine and they will make significantly more power.

Good info from Carey
If I was to choose from the options he listed, I would say for sure go with the flybarless head, stick with the 6.88 ratio (I'm not a big fan of super high motor or head rpms), and use 710 blades as gassers are heavier and perform much better in my opinion with a larger disk to maneuver the heli around as well as lift it better for autos.

As far as the power plant I run the Hanson G270 3D max motor with mine along with the 8oz century v2 pipe (screw in the supplied tip and it makes it quieter). A good all around combo in my opinion not the most powerful but plenty of power and good fuel economy. If you want to go all out you can go with the 29cc Carey talks about and/or the tuned pipe combos but I personally feel they are more work as they are more particular to setup then tuned mufflers -- not to mention louder.

My whiplash is just over 13 months old, still with the original motor/pipe combo from day one 489 flights to date so unlike nitro motors the gas motors will run almost "forever" at 489 flights we're talking over 140 hrs runtime you'd be hard pressed to get 200 flights / 30 hrs on a nitro motor without needed to rebuild it with at least new bearings and a ring.

That being said, you will get many many hours of fun and enjoyment and lots of practice time with gassers.
