I'll start with:
Receiver needs:
-A 3 or 4 channel surface receiver with a pair of 400mm external antenna's like the aircraft versions. Standard package size.
-A 3 channel micro receiver like the
R3104SB with twin 400mm antenna's, preferably conformal coated for small riggers or cramped radio boxes.
-A receiver with at minimum conformal coating to be more moisture resistant. Or on the extreme side a potted version with flying leads.
-Stretch: The ability to bind two FHSS receivers at once in master and slave mode for those who want some redundancy (twin guys)
-Stretch: A receiver with integral GPS
-Stretch: a FAAST and FHSS receiver.
-Stretch: onboard datalogging with optional video
Servo needs:
- A 300-400oz metal (steel) gear 2s Lipo capable servo with emphasis on durability over speed. Speed in the 0.200 to 0.250Sec range. O-ringed case, conformal coating on board. target price under $150. Stretch goal: brushless version under $175.
-A mini servo for throttle and mixture similar to the Hitech HS85 or
D89MW. Emphasis on durability over weight and speed. 0.20-0.25secs/60deg would be fine.
Radio needs:
-Would be nice if using a radio with telemetry to be able to replay a run on the radio. i.e. you just finished a heat race and were recording speed, GPS position, throttle input, steering input and and receiver voltage. If the radio could replay the race like a strip recorder. Extra bonus points if it could plot the GPS points on a built in Google map. Alternatively if the data file could be loaded onto a phone and replayed.
-For FE boats running a Castle ESC with telemetry I would love to see a configurable screen to show data. i.e. I just made a SAW pass, but cannot look down at my radio during the run, but when I can I would like to replay the last 10seconds to see what the data showed for Speed, RPM, Current, voltage, Temp, etc.
-Recall telltale function in the telemetry screen to show the highest value of a particular parameter during a session. i.e. max current was 550A or max speed logged was 98mph.
-Warning system when using FHSS telemetry receivers and the signal strength gets low. i.e. a pre-warning before the failsafe kicks in.
-A failsafe counter, a telltale system that counts or flags if a receiver went into failsafe at some point since the last power up.
Other:
A solid state water proof switch with better mounting options for a boat like a sealing ring and two piece case to mount to a lid.
