yes, I will drill may be 10 1 mm holes on the metal cover and put it back on. everyone is reporting it is running hot, with a cover like that just does not make any sense to me. I thought about lower the edges to touch the chip and put some thermal paste between then add a heat sink on top of the cover, but I think it is too much trouble and the two chips are not even/level when they are put on the PCB. so scratch that.
I think I will run this as 3.3V (and send a nasty note to the ebay seller
). if my calculation is correct that would give me close to 8 times range as the 10 mW module (did I figure this number right?), assuming all the other factors are the same. If the 10 mW can go 100-150m then 8 times would be around 800m to 1Km, that would be quite enough for most of my planes. these planes only have 7-10 min fly time any way. But I think it is fun to fly all of them FPV once in a while within 1KM.
I always want to see how it looks/feels as a pilot if you are doing fast continuous rolls five times in a snap in a fast plane.
I am going to use this as an easy plug and play vTx with a 2-3g cam so it can be placed on almost all of my planes (800-1000mm size). running through Rx power (range from 5V-6V, my planes have BEC outputs from 5.0, 5.5 and 6V) with one plug and go.
probably better to get a 3.3V BEC to work as a filter at the same time, then I can run anywhere from 2S to 4/5S main power pack. But that does not solve the issue of noise filtering and the cam is running on 5V minimum while the module is running 3.3V.
But since I already have this ebay 5V step up convert (in previous post), I am thinking adding a LM1117-3.3 between the Rx power (5-10V at most, they have different BEC voltages) then go through the ebay step up converter (which by spec only operates from 0.9V-5.0V, can I push that to 6V for a step up converter? So far the highest Rx power on my planes are 6V) as a filter then use another Lm1117 between the step up and this module to run the module at 3.3V. another lead straight from the step up converter to the 5V cam. The step up converter supposedly can handle 600mA current.
Too complicated? any issue you may see if I do it this way? (I just happen to have 2 Lm1117-3.3 laying around
)
IF I am not clear on my scheme, let me know.
The foxtechfpv 200mW module definitely is on the list to try. But I do have a set of 200mWTx+RC305 bought from HK, supposedly is Boscam (
http://www.hobbyking.com/hobbyking/stor ... x_Set.html).
could that be a genuine 200mW Tx? That is the one I will use for longer range FPV with fly time > 30 min with OSD. Like the AXN floater. Remember that one kilrah?!
I did not forget it, just too many fun stuff can be/need to be done.
PS: I do overclock my 2.4 GHz PC running at 3.2 GHz.
but I used Arctic silver 5 thermal past and a big heat sink with 120mm heat sink fan for cooling.
yep, overclocking is a c**p shoot. if you get a chip is capable you are doing great, if not, either it won't do it or crash and burn. I think my days of overclocking is over. It was fun though.
