    Default Modified Miss Geico V1 29 questions

    First off, first time posting so I apologize in advance if I commit an errors or if these matters have been addressed elsewhere. I have 5 minutes of downtime and took this opportunity to reach out to as many of you as I can far more knowledgeable than I.

    Situation: MG29 V1- stock 1500kv motor (2000kv dynamite on the way)
    Mods: Stainless prop - factory pitch and diameter (sorry, I do not remember the specs, I put it on long ago before I put it "on the shelf.") Dynamite 120a receiver. Offset rudder, upgraded flex shaft. Batteries - #2 lipo 3s (6s total) 5000mah 50c.

    Problem: Proper propeller! I have read and read, and whIle I have learned a great deal about the whole deal, I am in desperate need of suggestions per my current (1500kv) setup and soon to be (2000kv) setup. With all due respect to anyone who is kind enough to provide suggestions, the "trial and error" method is not an option...I am a full time student and cannot blindly blow $20 per prop for experimentation.

    Purpose / Goals: speed of course, but most importantly - conservative reliability so I do not let the factory sealed smoke out of expensive components!!! Ive read enough to know the dangers of under and over propping, I just don't know where to start.

    Thanks in advance for anyone who takes the time to share their knowledge and wisdom.

    Thanks so much for your input! I had no idea what to do with this. I will get that ordered and get back to you, with a huge thanks I'm sure.

    Next question.... it appears the Dynamite 3910 (6p 2000kv) motor and the Dynamite 120A esc are both rated to handle 4s in series (14.8 + 14.8v) or 8s. Has anyone tried this? Results? Recommendations? Propeller size?

    Thanks in advance for anyone that contributes!

    Maybe a good place for this.. since I'm kinda new as well.

    Will changing the prop to the fore mentioned Octura 642, sharpened, balanced, etc. have any negative affect on the 120A ecu on the Geico 3V?? any chance it could burn it up?

    tia,

    tia,
    You won't pull too many amps for a 120 speedy. As long as you are not trying anything silly like 6s. Is it a stock setup?

    Yep. 100% stock on 6s
    5200mah, 50c, 3s x 2

    Would that burn up an esc?

    Its the recommended battery on their site:
    2 × 2S or 3S 50C Li-Po batteries with EC5™ connector

    If you have been running on 6s you should be fine. I am not familiar with the new ESC. A 642 is not going to push 120 amps on a Gieco. It is just some of the other 120 ESC's don't like 6s, that is why I asked the setup.
