Default Trinity Speed gems

Just wanted to know if these are decent motors. I am looking at the 13 double with the D3.5 amuture. Is this motor a relible capable motor. I run 1:12 scale carpet 8 min 4 cell 3000 batteris with a Associated RC12LC chassis open class. I compete with guys with 10 turn motor which are a bit to low for me. If you have any other suggestions post them. Thanks!





Torque Nmm: 212.8
max rpm: 31.701
max power watts/rpm: [email protected],595
power watts/rpm: [email protected]
time to max power: 0.57

They're great motors. I run a 12t in my 1/10 scale. I saw one guy at my track use an 11t in his 1/12, but didn't see him race with it (just practice). Thing was ripping up everyone and flipping all the 1/10s over. I would think a 13 t in with a 4 cell 3000 should last 8 min.

Speed Gems are excellent motors. I still have an Onyx(14turn dble) that I bought years ago. Its still a good motor now, and was great when I first bought. It was more than enough to help me keep up with the handwounds. At about $20 less.

ive had two speed gems (14t onyx and 9t zircon) and theyre a great value, almost 50% cheaper than hand wounds. theyll last long with regular maintennance (cleaning, comm cutting, brush replacement).

I agree with everone about the Speed Gems... Inexpensive, and lots of performance, I have run them in touring car, Offroad Trucks, and rally. All of them were great, and I could hang with the handwounds... have run 9t 12t 14t... U cannot go wrong with them... The only time one of these motors failed me.. is when I overgreared it, and gave it a little too much timing,.. oops melted endbell.. but any motor would have done that.

Another motor that i'm thinking about is the peak STRATOS which seems fairly good. I'm leaning towards the 13 triple in the peak line up. Is this motor any better than the speed gem. I'm looking for relibilty and a motor that is easy on the repairs.




13 turn triple
power watts/rpm: [email protected],990
Max. rpm: 38,150
Max power watts/rpm: [email protected],286
Torque Nmm: 195
Current: 138.6
Time to max power sec: 0.64

In this compairison the speed gem had 0 timing and the stratos had 6 timming.

The Speed Gems are known for having soft enbells that are more prone to melting than other motors. If you have an otherwise good Speed Gem and melt the endbell, replace it with one of the regular Trinity modified endbells. They'll withstand a lot more heat.

I really like the Speed Gem line, great bang for the buck.

Thanks for the info on the endbell... I have melted two em.... thought it was me... Last one... 9t... I put the arm in an Integy Atlas can... Put some copper brushes in it ..shimmed it up.... and it ran for ever... I put man... 15-20 packs through that thing before I cut the comm... and it was not bad. Now I have a Fantom Ti... but that old Frankentrinity is my backup.

wel, i also had a melted endbell on my 9t zircon. before that, my 14t onyx had one of its magnets come off the can. but those two incidents happened after many months of racing and practice runs. i just put the onyx enbell on the zircon can, and i had a spare armature. i also put CA on the zircon magnets to be sure, and i avoid running the mod motor for more than 5 min to avoid overheating the endbell.
