First off, a big thank you to everyone on the form for sharing such great information and the mod's for maintaining a wealth of info - as a new builder I was able to get through entire build without having to ask any questions.
6sEXB / Castle 1717 1650kv / MMX8S / M2C / PPS / JBI / ALZA / GCRC
TLDR Pic:
The build in chronological order:
Planning
Phase 1 start
Roller arrived on mother's day, thanks FedEx
Parts laid out for assembly
Was too excited to get started and forgot to take a 'before' pic
Fully broken down
PPS motor mount
Reassembly
Phase 1 complete!
After several packs I identified the following items to correct in Phase 2:
1. My makeshift servo mount extension was twisting / not going to work long-term
2. Motor was quickly getting to ~165 temps even with 18/50 gearing and would need fans
3. Tires were good but not great
4. MMX8S fan already broke
5. Spektrum tx/receiver felt slow and was a pain to switch between cars (with and without gyro)
6. Lots of un-necessary wiring
Phase 2:
JBI mount was a pain to get in; even after prying it into place I found the stock screws were ~2mm too long and need to file them down as I didn't have any of correct size:
I went with with K8 heat sink with some .5mm thermal pad to make the connection
GCRC 'Maximus' (50mm) motor fan would not fit so cut the body for a cold-air-intake kind of thing
GCRC 'Typhoon' ESC fan required different screws than the MMX8S so used an M3 tap to get it together
Able to stuff Flysky FGr4 and castle bluetooth in the stock box.. barely
Phase 2 result:
Phase 3 will be mostly cosmetic/reliability and will begin when I have a significant breakage (already stockpiling parts
).
Overall very pleased with the build, averaging ~130 temps in 90+ ambient on 20/50 gearing and handles great. Full weight comes in at 15.4lbs. Only regret was not including ceramic bearings in phase 1; now am faced with the daunting task of tearing everything apart to mark project 'done'. Only other regret was not building sooner.
And for those interested here's my gearing on 6s with backflips. I haven't GPS'd it yet and I don't really care to, but I think the 46mph calculation below is very conservative.
