RcMonster Motor Mount For Ofna dm1e

[jhautz]

If you just want the bigger pinion for a cheap as possible then you really only need the revo spur adapter. Putting thr smaller spur gear on leaves alot if room for a bigger pinion. That would be the ceapest route.

Every tooth you take away from the spur gear leaves room for one more tooth on the pinion. Going from the stock 49T spur to the revo 40T gear let's you go up 9 teeth on the pinion. The smaller revo gears will give you even more room for bigger pinion.

When I bought my adapter from RCM it even came with the 40T revo gear. Not a big deal, but saved the $5 to buy the gear too.

Ok I started building the dm1 e , drilled bigger slots in the stock motor mount to allow me to fit a 1717 , used all three screws to hold the motor so it is secure as possible , started to dremel the chassis a bit to allow a bigger pinion and then decided to stop as the 1717 is heavy and if I get to close to the sides of the chassis that motor will prob crack the chassis or fall off. Ordered the rc-monster single speed adapter , hopefully I can go bigger pinions with this method , does it come with a revo spur bc it says it comes with a spur ? Ordered the 8mm revo version ? What is the next step I should take ? Thankyou

My experience with the DM1-E in the short time I've had it:
1. The standard chassis is fine but the standard motor mount is awful to use and not only do you have to get pinion/spur mesh right but also angle of motor at same time
2. The standard spur is fine providing you don't plan on high speed runs. You can fit a 20T pinion with the 49T spur and I'm getting blistering speed with Tekin 2250/RX8 on 4S on a GP standard race track. You will need to file out slots to get this pinion in. The RC monster spur is also OK if want to use smaller pinions to get same gearing or want to use for high speed runs (not my thing). It is narrower than stock one so will get chewed out easier. Also check screws - they aren't threadlocked and WILL come loose (wasn't impressed when 3 out of 4 fell out after one session). Same goes for stock one - nut holding spur came loose after one run.
3. Don't rely on using the SNR CF chassis with it's extended slots to use the standard motor mount. Mine has a hairline crack in the chassis on the outer slot after only 2 light sessions. Otherwise is nice chassis but not sure if worth the $100 over the stock one.
4. The RC Monster motor mount is great and what the car should have come out with in the first place. Still the kit is only $250 US or less so I suppose that's why!
