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 partsrotor head
the FBL version will have better performance as you don't have the drag from the flybaravailable gear ratios
- 6.88 - stock ratio
- 7.29 - optional ratio
there are three on the market that have some track record in no particular order
- TRM 270TT - high rpm - use with the 7.29 ratio
- BH Hanson 29 3D Max - use with the 6.88 ratio
- 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
here are some options
- Hatori SB12 - highest performance with the TRM engines. Its expensive but very high quality
- Century Torpedo slim - seems to work well with the Hanson and HWC motors. Its a bit loud but very lightweight and mid priced
- 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
- Hanson tuned pipe system - best power with the Hanson engine. It will bolt right onto the whiplash. Its sound is loud and raspy.
- Quickdraw pipe - best power with the TRM engine. There is a configuration for the Whiplash. Its sound is also loud and raspy.
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'sgenerators
not required but can be useful for long flight times with small/lightweight batteries
two out there
- Jewel - long track record but you'll lose the option of spin starting. It requires adding some mechanical parts.
- 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.
