Polaris hatches and radio installation
 
6 Attachment(s)
The following pictures of two Polari, including my ancient and battered Polaris #1 (fourth season of flying) may help to answer some questions about where the servos go, how the hatches are done, what sort of cooling can be used, etc.

hey anyone work on making the hatch more watertight? I have done the following with mine: built up a rim around the hole and then made a hatch lid over the rim to hopefully shed water better. Will also do the silicone+saran wrap trick to make it seal even tighter. I am just using elastics for now. What glue do you use for the magnets?

Put my servos on top of the aft fuse and added grease to the gears to repel water entry, maybe add a splash guard over them also.

REALLY like your hatch :eek: i use rubber band in most of my battery
hold (dont like velcro)

i had one flip over : need to access servo anyway :mad: ... water always find its way so exposed servo is a good idea for easy maintemance & exchange :D

dont forget the ESC cooling ...

ESCs - always seems to be a big concern with the Polaris. I presume because of the high Kv? Or is it because of the very long motor leads? Partly why I did not order the Modelaero ESC, and found my own which looks like it should run cooler. I will also run a separate BEC to keep ESC heat down. But most of my planes have the ESC stuffed inside - just my FPV planes have them in airflow. This big heavy HK ESC has a pretty large heat sink on it, and we have a cool climate here also. Will do some testing today on ESC heat.

Love the RCAF targets. I just got a bunch more myself, and will stick em on soon (My Zeph has them also)
