    Open Letter To SJFE

    SJFE, thanks for all the reasearch & developement you have done.

    i bought two HM200 amp escs and encapsulated one like on your 26 inch cat. the other i left as is on my twin 42 inch 13 pound twin geared/drive cat.
    todays run on 18 mph winds and some chop still managed 41 mph on the X447 two bladers.
    what was interesting were the temps. nimh cells were 115' , water cooled fiegao motors were 100' , as is esc 114' and the encapsulated esc was 106' .
    the escs did not like the pistix adapter so removed it out.
    and with the 4mm "O" rings on the teflon tube between the gap of stinger was a perfect fix. this time noot a spec of water was inside the hull.
    again, thank you.

      You are more than welcome. Now more than ever we need to try and save money where we can...with minimal risks. This R&D has paid off well. Lets hope we can find more products like this.

        took 3 days fed ex. key is to buy at night close to midnight.
        make sure you test it before encapsulating it.
        did not install the tubes like SJFE did. next one i do, i will maybe soldered onto a flat piece of copper on bottom.
        i was pulling 66 amps so i unless you run close to 200 amps it might not need the extra heat sink.
        DP270 was great. it is alot like syrup.

          Robert I agree with you on the tubes. In retrospect I would not do it again either. I will use plates and fans from now on. The DP270 is a great product!!!
