Need your inputs on which motor to keep.

[MartyBoy]

it's a long story but i have 3 engines and i need your inputs on to which one to keep, as I'm fairly new to the hobby. i have an hpi 15ss motor, a hpi t15 that comes with the evo, and an os 12 cv-rx with 10e-r carb. i don't plan on entering any races just having fun with some friends in a parking lot. my chasis is currently an hpi evo. naturally i'd like the car to be fast, but my current funds are limited with these 3 motors. i also don't believe in the specs listed on the web sites of mill manuf. and would love your inputs.

Thank you for any advice you can give me, i really appreciate it.

Sell them all and get a novarossi...but seriously, i'll be they're all pretty good engines. But if it was me, i'd go with the O.S. just because they make really good, user friendly engines.

I'm with kwong, but don't sell all three. Keep the os 12cv-rx. It's a good engine, holds a tune very well and is well suited for a beginner to hone their tunning skills as well as not get into too much trouble with an overpowered car.

Sell the other 2 and add a couple of extra bux to it and get the Novarossi NS3S121A. I'm a little biased towards that engine because I just got mine and even though it's still being broken in, I know she's gonna be a performer.

You'll be satisified with the OS 12cv-rx for now.

so keep the .12 motor, and sell the hpi's? I've been running the .15 hpis and feel comfortable controlling the car at high speeds. will the os be a slower motor or do you guys just hate hpi as a company?

 

[kwong2001]

Well the O.S. is a legal race engine...and yes I am a little biased towards O.S. as opposed to HPI.

Well, I have personal experience with the OS engine you have. Great performing engine. Holds a tune very well. It also has a good life span if not abused. Mine lasted for just about 5 gallons approx.

The HPI engines I have seen and dealt with personally is the stock one that came in my brother's SuperNitro Rally (Nitro Star .15). Doesn't hold a tune very well and not much fuel through it. The other one is the .25 that came in his savage ss. That one is doing fine.

IF you want a performer, sell all three and get the Novarossi Kwong and I suggested. It will out perform your .15's hands down. It's a little touchy for tuning but not impossible if you have moderate tuning skills. For a beginner, it's a challenge. This .12 engine, as well as other racing engines, proves the myth that bigger displacement engine's are better, is not always true.

 

[kwong2001]

Diver, to be perfectly honest, the novarossi we have really is only for people who really have tuning down to a science. Cuz you can fiddlesticks up the engine so fast if it isn't tuned perfectly. I know I ran my first gallon way too lean cuz I really didn't know better, that's why I had to get the sleeve pinched so soon.

But anyhoo, yes there's a big difference between sport engines and race engines. It's like comparing my Corolla to an STI.

 

[Diver6127]

I agree, the race engine's can be finicky. SO with that said ... sell all of them and get a Black Pixie. It can be tuned by an average person fairly well. If you're going to race at the park and don't plan to race at an organized race, sell all three, get the new OS .18 cv-rx. Use the extra money left over for more stuff for your car. The .18 CV-RX is averaging about +/-$160.

Gobs of torque, easy to tune and good life span (if it holds true to the OS name).

allrighty... so for the removal of the flywheel on thehpi motor... is it a screw on or a pressed fit (special removal tool is needed). since I have the t15 apart i might as well see if i can run the .12 os.

 

[Diver6127]

The flywheel is pressed onto the collet via pressure from the clutch nut. take off the nut and you can either go to an automotive parts place and get a small gear puller or just get a flat screw driver and use that to tke off the flywheel. DO NOT just pry it off in one swift mvement. Just slip it in and twist it back and forth lightly till it pops off.

 

[kwong2001]

Well if you removed teh clutch nut. Then just stick a flat head screw driver in between the flywheel and the block and just pry it out.

Be careful not to mar the bearing that's behind it though if you use a screwdriver. Just because your not using the engine doesn't mean you shouldn't take precautions against damaging the thing.

Thanks for all your help everyone... I really appreciate it.
