i tried to fire up my Hyper .21 again today, and no luck.
either this thing is brand spanking new(which it looks like it) or Hyper .21's have godly compression.
i took the head off and took the back plate off to look inside the block to see if it was "broke". it looks fine.
i took it to my lhs and asked him why its so hard to turn over and he said "thats the way they are.....mad compression"
so im back home and trying it again. plop it on the starter box(which took awhile to put together cause the directions suck *****) and nothing. all its doing is spitting rubber off my s.b. wheel everywhere. i let the starter box battery charge for like 20 hours, but it still wont turn over the engine....its just stops the motor on the starter box.
im gonna let the battery charge longer on the s.b. since its brand new. maybe thats the problem.
its the pink ofna box so it should work fine.

The hyper .21 is extremely tight when they are new. They are really too tight and not a very good fit. I ran 4 tanks through my hyper .21 8 port and never got over 190 degrees. When I took off the head to see how break in was going I noticed that at TDC the chrome on the sleeve had been stipped off and brass was showing through. OFNA is replacing the motor and they said that it was an incorrect piston and sleeve match. This is a common problem however with this motor. You could always try cracking the glow plug loose and getting it turned over that way. Also head the head and case of the motor with a hair dryer before trying to start. Good luck

Chuck up the clutch nut in a 1/2 inch drill and pull the glow plug and oil it up and spin it over for about 20 min. I had to do this with my .12 PICCO to get it like pre break in before the SB would turn it over also heating it up before this helps also

after another full night of charging the battery was good to go on my box.
and my car started right up.
finally got it semi-broken in and tuned (although in rainy weather). next sunday when it gets nicer out, ill run it again.
i did however ruin my tires running on asphalt, but oh well ....life goes on.

Do not drill anything - This engine is just extremely tight. It is like that to give better compression.
I have a Hyper 7 PBS and it comes with an OFNA starter box. It is not powerful enough to start the car. I had to buy a more powerful starter box from OFNA. Then it starts everytime.
Make sure the piston is at the bottom chamber when you start it up and after you cut it off. Do not let it cool down the the piston at the top of the chamber. It can hurt the motor.
After about 8 - 9 tanks you will be happy. It is a very good motor.

Man, where you guys been?
Drilling?
More powerful box?
None of this is needed, all you have to do is heat the head up to operating temp and the thing will turn over like butter.
Use a hair dryer or a small hobby torch, dont put the flame on the head, just let the heat transfer to it.
Engine will roll right over.
Works time and time again

guys did you read...i got it started fine. it was the battery powering the box.
the motorcycle battery in there took a long time to charge up on its first time.
after that it works like a champ.
no drilling
no new box
no heating anything up
you gus did offer some good advice i might need or others might need later but like i said, it was the battery not doing its job.

The Pink box with a good battery has enough power to start a V8.
Heating up any new engine is a good idea and we use it all the time. Reduces stress on the engine's internal parts on those first few new engine starts.

best thread Ive seen on this site so far!!!! atleast the most helpful to my recent problems. Ive just switched to a starter box for the first time along with a new (rebuilt) .15ss engine. Im having hell getting it to turn over. at first I used the 2 6cells but decided to go with a motorcycle battery, I can get it turnin over but now Im just having hell getting its started. been a very frustrating couple of days, got the big battery on charge right now, gonna give it a go in the morning before I head to the track and look like a moron when I ask for help

Make sure that the wheel is going the right way.
I just got a box that thad all tamyia connectors
so that you cant reverse polarity, but it was spinningmy motor backwards! I didnt even suspect it because why would it
be wired up backwards? But it was and I fixed it and it works
now...
BTW that hair dryer idea is GREAT! It totally works...

The motor in the Hyper 7 PBS - OFNA claimed that the pink box would bot even turn it over. Needed more powerful motors. With the box I posted that I bought earlier. I do not need to heat anything. Just make sure piston is free and starts every time. But if you like the pink box, that is cool.

PART NUMBER: 10255- w/Power Panel
PART NUMBER: 10258
Used For: 1/10 On Road, 1/8 On Road
This is the box I was referring to. It only has 1 motor. It has the same high torque single motor as all OFNA boxes.

I have this box. It is an:
#1750 Team Associated Starter Box
It works great. The only problem I had is that it
comes wired for an ntc3 so you must switch polarity
to get it to start belt drive cars.

yeah set the car on the box, line up the starter wheel with the flywheel and press down. sometimes you just bump it a few times some people press it all the way down and hold it until it stars. I imagine both ways are fine.

i have to bump my mugen motor,if i just put it all the way don then it boggs the starter box and get just stops,but if i bump it,it usually starts on the first bump,but sometimes takes a bump or two.
