Default Ofna .32 question?

I just ordered one through Tower Hobbies (thank god for promo codes!) Anyways, I was just wondering if anyone had one in their savage or any other vehicle. Does it have decent power? I didn't want to spend too much and I already had the roto start back plate that will fit laying around.

Not to be negative about your new purchase, but that .32 wasn't neer as powerfull as some 7-9 port .28s that i run.
I got mine, and trashed it right away.

If your looking for a mellow powerband throughout the RPM range, youll get it with this. Just dont expect to have a monster in your hands..


But let us know what you have to say about it. it may be the perfrect engine for you.

The Force 32 is a great bashing engine. It's down on power compared to some others, but it still has a nice fat torque curve that makes the engine enjoyable. Have fun with it.[8D]

I have seen 5 and 3 port 28 out run this engine on the topside. Great low-end torque engine but not much on the topside.

Thats what I figured, and for $128 shipped, can't ask for too much more. Its definitely for bashing, and since I have the backplate, it seemed like a no brainer.

I have a OFNA FORCE .32 I love it ..Compared to a stock .25 stock 4.6,and a COLLARI .32
its the best Ive had so far.
It will hold a tune better then you can imagine..starts right away....dont burn plugs...It has plenty of power..more low end then the COLLARI,but not as much up top.
I just bought an STS .30 so we will compare soon.
Excellent choice with the .32!
PLUS
It uses the same one way bearings,and pull starts as the HPI star .25.
Be careful on the pull start ,it has a TON of compression... and you'll blast through pull starts, IF you do not losten the GLOW PLUG before you try pullin.

At .32 is probably one of the worst purchases I would ever make. I would get a good .28 or .30. They will have all the torque and speed I would want. But I dunno I hope the motor works out good for you and hope you have a good time with it.

Yeah, thats all I really want, and again the price was less(some a lot less) then the ones mentioned up top. I have all the speed I want with the jato but I need my bashing fix with the savage. Thanks for the replies.

The buyer didnt hold up his end ,and the seller offered it to me at the high bid of 119.99.
Email him on the side ,maybe he will come off another 1 that cheap too.

I'm with alvinm on this one. my savvy is an off road monster. that's what I built, if I want speed, my Cen CT4S will push 78.4MPH and that's my speed fix (besides my ride, but that's for a different forum). having some sweet low end to lift my front end at will, now THAT'S POWER. MONSTER POWER. just my 10 cents.

May be I over looked it but I do not see where it says it is the newer version REV 2! Might be the older version and is why it is so cheap trying to get rid of them?

He said they just arrived,and also said it was rev2 with the tighter pinch...but ya never know till you have it in hand.
How can you tell the difference?
3001= pull start
3002 = shaft start

Default RE: Ofna .32 question?

Anybody out there, I picked up a force.32 That I want to install in a MGT, I looked on the ofna web site for factory needle seeting , because I sealed the motor & want to start from there. they don't have anything on the .32 only .25&.26, would it be same setting? I e-mail ofna on friday with still no responce,
I know some say it's not a good motor but I have it (no more money for different motor) it should be better than the stock .21
If anyone can Help???
thanks

The flush settings on the LSN and HSN are universal defaults amongst all engines.

Thank You Gravediggerracing
I see you have an Axial.28, how was the break-in? I put a axial .32 in a warhead, just can't seem to get it right. did the pinch test Abou2-3 sec. an dies, I read thats good,but it ain't right, sounds like it wants to die at 1/2 throttle(gurgeling),I'm thinking to rich????
And I can't hit 2nd gear,lots of smoke TEMPS spike up quick 2-5 min tops To lean?????

The break-in was simple. It was ready to go at about 5 tanks and I was leaned out and rippping at around half a gallon-I love this engine. My only complaint is that I can't keep the front wheels down. As for yours, lean the HSN some until you get it to shift into 2nd. Leaning the HSN out also leans out the LSN too, so if it still wants to die at 1/2 throttle, lean the LSN a little....it shouldn't take much. Always do the HSN and LSN adjustments a little bit at a time.....and don't mess with the MSN because it's really not needed.[8D]

Thanks gravediggerracing,
I think I found the problem with 2nd gear, I took the warhead in to lhs cuz I could not get it running about 2 1/2 months ago, wound up not having an o ring on the gas cap ( never would have found that) they told me the spur gear was bad, I told them to replace with a steel gear and hardened clutch bell from robinson racing, never got the stock motor running, thata were the axail come in. I dont think they put it together right as you can see

If that slipper was loose, it wouldn't allow the trans to shift because the trans rpms wouldn't be high enough to engage 2nd. A too rich carb will do the same thing. Low rpms=no shift.[8D]
