XRAY XB8 Conversion Suggestions

Thanks for the input.

I currently have a TQ. If the brushless conversion goes well, I may add the front tower and new shocks to bring it close to the EC spec. I haven't been racing for a while, so that is the only reason I have not updated to the EC yet. If I was going to continue with nitro I would definitely update to the EC spec as it has made a noticeable improvement with on track handling. If the TQ handles ok with the new weight and balance, I may just leave it be, and start to work on the XT8! Yours conversion looks great, very clean and well done. Hopefully mine will resemble yours when I am finished!

That was a concern of mine with the Neu/MM combo. Some posts said it won't work at all, others seemed to say it will work ok with some adjustments. Do you think the general concept of a smaller output motor, low weight design is viable in a buggy?

I am not fixed on the MM or Neu if there is a better pair to put together. Is the Lehner in a similar power category as the 1509's power output? Do you have any suggestions for a place to purchase a Lehner? It is a 2-pole motor that works better with the MM, correct?

Thanks again,

Bryan

Yes the MM / Neu combo is not good IMO. I would recomend a different speed controll or a different motor. The MGM or Quark speedo with the Neu. The Lehner or Wanderer with the MM. Either way you will be fine.

Yes the MM likes the 2 pole motors. If you are looking for a 2 pole motor that is comparable to the 1509, that would be the 1930. I think someone already recomended a 1930/10. I have acctully run a 1930/10 in a buggy with some good success. For a while there i was in love with the small motor lightweight setups, but in the long run the bigger motors just run cooler and you really arent gaining a really noticable amount of run time. In the end it takes a certain amount of energy to propel your 8lb buggy at the rate you want. You can make a smaller motor work harder to do it or a bigger motor do the same amount of work with less effort. Either way it takes the same amount of wattts to get the thing moving the way you want it to move.

That being said... You could really split the difference and go with something like a 1940/8, target a 30K (or even a little less) rpm motor speed and and have a nice cool running efficient race machine with conservative smooth power and more than enough speed for the track.

Then if you ever did want to go crazy just bump yourself to 5s and let er rip.
