Hyper/Picco .28 Massive Issues
 

Alright, well I just got the Picco .28 with the Truggy Box today for my Hyper.

And Im having massive problems getting this thing to turn over.

It seems to get stuck at TDC, and once that happens, its extremely difficult to move the flywheel by hand. The box cant do it too. It rotates freely before it hits TDC.

Now yes, I know there is a lot of Pinch, but how do I get rid of it without even being able to start it.?

It just does not turn over.. Ive put a coupla drops of ARO in the glow plug hole + carb. I even removed the Head and Button and tried to check if something was wrong, it still gets stuck at TDC..

Anyone have any ideas on how to get this thing started.?

Before anyone asks, Ive done the following :

Few drops of ARO
Heating up the engine
Loosening the glow plug to taking it out completely
Charged the batteries completely for the starter box
Flywheel is aligned properley.


Oh and BTW, im using 2 7.2V stick packs for the box, so its not that its not getting enough power.

Any Suggesstions.?

Thanks..

RE: Hyper/Picco .28 Massive Issues
 

Heating it up should allow it to turn over. How hot are you getting it? I'd see if you can get that sucker up to 200 before cranking it.

RE: Hyper/Picco .28 Massive Issues
 

The hair dryer gets it to a maximum of 130 - 140

I dont have a heat gun [:@]

Ughh.!

RE: Hyper/Picco .28 Massive Issues
 

Yes, heat gun is the trick. I'm having the same problems with my new OS 18 TZ. As soon as I heated it up to around 200 it turns over freely.

Good luck

RE: Hyper/Picco .28 Massive Issues
 

Well thanks but im gonna have to break it in at the air field.

How am I supposed to get it upto 200 and start it up [&o]

I dont have a portable heat gun, as a matter of fact a normal heat gun, and I dont have a portable hair dryer [&o]

Any other suggesstions.?

Thanks.

RE: Hyper/Picco .28 Massive Issues
 

Over-charge your batteries....

My box gave me heck the very first time I tried to start my Nova 28, but now it starts without the least hassle - and I don't have a heat-gun either - and I'm sure it's colder here than where you are...

I just have a single-motor TT box with 2x LRP 3000 bats... Haven't even charged them to where they get really hot.. And they've started the Nova three days in a row without recharging.., basically immediately...

So my guess is, lacking a heat-gut, double-check and/or re-charge the bats!!....(or get some new stronger ones... [:@])

RE: Hyper/Picco .28 Massive Issues
 

Me and 2 other friends had the same exact problem with our Picco .28's. My wifes hair dryer got it to 200 degrees and it would barely turn over. That is the only thing I know of besides leaving you glow plug loose. You are going to have this problem for awhile even after break in. I had to bring the hair dryer to the track with me to get it to start up and now after 17 tanks through this Picco .28 it still gets stuck on TDC often! I still have to use a screwdriver to turn the flywheel back to BDC and then use the starter box but it still has to be warm and I am using the OFNA Chrome top starter box with the single high torque motor with a Motorcycle 12V battery! The pinch is SICK on these motors.

another reason i Love my Break in Bench. :)

RE: Hyper/Picco .28 Massive Issues
 

Yes those are good but &%$# how many tanks do you have to put through this motor before I do not have to worry if it will turn over when cold! I mean I melted my stupid connections on my starter box twice before getting it to turn over decently now!

RE: Hyper/Picco .28 Massive Issues
 

Picco 28 is actually a pretty easy motor to break in...some of the .21's like a Go 7 port are even worse...

a huge key is to be 100% sure your wheelof the starter box is lined up square to the flwheel of the motor...... Its amazing how much torque you can lose of the wheels aren't perfectly lined up........ If you didn't remove your motor to line the wheel up your most likely not 100% lined up.... even experts at setting up starter boxxes will remove the engine to be sure everything is perfect.... As well be sure your getting good contact between the flywheel and starter wheel...RTR flywheels are usually too small to make good contact, and in some cases you need to shim the motor onthe starter box up to get better contact....

RE: Hyper/Picco .28 Massive Issues
 

the key to a Picco is once you get them running, keep em running !! we do not shut them down to heat cycle like other mills...we will run several tanks back to back... we also will push them a little harder then other mills to get em to loosen up...... Most pro's don't even break a Picco in, they just get em running and hit the track, change con rod at 2 gallons and all is fine......... These mills use very high grade metals and will hold pinch for a very long time, but they also will last for a very long time... only weak spot is conrod ( same as any mill)

RE: Hyper/Picco .28 Massive Issues
 

Make sure the flywheel isn't stuck at TDC. Heat it up. When depressing the Hyper on the Starter box press it down slightly to get the starterbox at maxium RPM then press the rest of the way down on the Flywheel. I was having the same issues till I let the starter box get going first, then depressed it all the way and it fired it up right away.

RE: Hyper/Picco .28 Massive Issues
 

Do you have a Picco .28? I even put a spacer under my starter box plate just for the reason you said and my friend too and it is still the same. At least they are not that bad now. I mean do not get me wrong the pinch is great and should last along time compared to other motors I had the you can turn them over easliy when new.

RE: Hyper/Picco .28 Massive Issues
 

Nope I don't have the Picco .28. I have the OS 21 V-spec but some ppl don't know to let the wheel on the starter box spool up first as that will give you maxium Torque out of the Starter box. I learned the hard way :)

RE: Hyper/Picco .28 Massive Issues
 

If all you have is a hair dryer, try wrapping the cooling head with tin foil or maybe even a sock :) Anything to keep the heat from escaping. Put tinfoil on the opposite side that your heating from to help reflect some of that heat back at the engine block.

RE: Hyper/Picco .28 Massive Issues
 

I JUST BROUGHT A HEAT GUN TO DO MY FLOORS FROM HOME DEPTO 49.99 THAT THING GETS UP TO 800 DEGREES

RE: Hyper/Picco .28 Massive Issues
 

ahahaha!! Go to any place that sells tools they should have a pretty cheap one. Also try tapping on the flywheel pattern with a flat screw to get it unstuck, then get some lubricant and put it in, then heat it up AND loosen the glow plug. If you wheel on your starter box is lined up properly should work fine and you battery has to be good.

RE: Hyper/Picco .28 Massive Issues
 

hmm i know what i did was i used a hair dryer get it up to as high as it will heat the motor then dont hold it on your bump box just gently hitting the flywheel on and off the bump box wheel and lossen the plug half a turn thats what worked for me

RE: Hyper/Picco .28 Massive Issues
 

harbor freight tools 9.99 for a chicago orange heat gun :) gets up too 500 thats what i bought

yea and I have a jpx.28 so I ran into same **** buy a 12v so you have extra battery for your bump box you need to losen the plug up just a tad fire it up and do not let it die !!! run like 6 tanks threw it seriously i feel your pain haha!!! if I kept mine runing though would have been easier bring batterys fresh plugs after you soak the ones just to give it that nice pop

but hey i got mine runing and I love it now it turns over not a big deal I almost have a gallon on it

RE: Hyper/Picco .28 Massive Issues
 

Wow, thanks a lot for the suggesstions

Just waiting on my batteries to charge for the starter box, It drained 4 3000MaH batteries trying to start this thing.!?

They're aligned perfectely, In the end I gave up and even tried using my hand held airplane starter, it just changed the colour of my flywheel to green [&:]

Ive never seen an engine with so much pinch. Quite amazing.

The main thing that sucks the most, our track dosent have an electrical supply, otherwise Id run to Acehardware right now and pick up the first heat gun I could find.!

Ill try and get hold of a 12V gel cell tomorrow, but for the time being, ill use the stick packs.

One of the reasons I got the truggy box was because I thought id have the least amount of problems trying to turn anything over [&:]

Well let my batteries charge up, and ill try and start it, and let ya'll know

Thanks Guys :D

RE: Hyper/Picco .28 Massive Issues
 

Hey Qaiz..So are you getting your hyper to the track tomorrow? You will enjoy the picco once it starts. Good luck!!!

RE: Hyper/Picco .28 Massive Issues
 

Oh yeah!! That picco blew my mind compared to the SH .28 and Axial .28RR I have. It has so much torque and will smoke them in a heartbeat. I used to love my Axial and now it feels like a SLUG!!!

RE: Hyper/Picco .28 Massive Issues
 

YES, THANK YOU GOD.!

I managed to get this thing to turn over.!!!!!!!!!!!!!!!!!!!!!!!!!!!

While in doing so, Ive practically destroyed my starter wheel.! But I got it to turn over :D

But Lord there is SO MUCH PINCH.!

It just needed a lil push, a few more drops of ARO did the trick :D

Ill be breaking it in tomorrow.!

Thanks a Lot guys, it really helped.

But it suprised me, I didnt pre-heat the engine at all, ambient temps are around 75, and it just buzzed!. Im so happy it turned over :D

And heres the culprit

Thanks again guys, Ill try and get a vid up of the break in tomorrow :D

RE: Hyper/Picco .28 Massive Issues
 

HAH! Thats funny. I did the same thing! I had rubber from my starter box EVERYWHERE!!! At least you got it started. Wait till you feel the power. I had a SH motor like yours in a couple of truggies I had and in no way whatsoever can the power compare. Do not get me wrong, I love my SH motors (Easy to drive and hold a tune awesome) but I love the power of the Picco.

RE: Hyper/Picco .28 Massive Issues
 

Thanks :D

Yeah SH motors are pretty good, Im gonna try and shove the SH I ripped outta this into the Nitrage.

I honestely CAN NOT wait to get to the airfield tomorrow and start this thing.!

And from the things Ive heard about the Picco/Jammin engines, all I shall be doing is battle for throttle control :D

I just tried to get it going again, its starting to turn over alright now, not as much drama.! And less destriction of my starter box wheel :D

RE: Hyper/Picco .28 Massive Issues
 

My buddy has almost a gallon on his, his pinch has finally tamed down a little so the box can actually turn it over,
he destroyed his flywheel having to pry it from TDC

RE: Hyper/Picco .28 Massive Issues
 

He's not even broken in yet !!! you boys just wait till gallon 2 and that motor starts to really wake up..You guys have honestly only see a fraction of what that motor can do... Your using a 6.25 mm Mach carb and the motor still had full metal pinch............. 2 gallons and you loan him your 9 mm LRP carb then you can seee what a Jammin 28 is all about !!!!! that Mach carb will be taking a big chunk of HP away from that motor !

RE: Hyper/Picco .28 Massive Issues
 

Now you see why I made the comments I did when people were insisting an Axial 28 was a viable competitor to a Picco 28 ..

RE: Hyper/Picco .28 Massive Issues
 

Yupp I have about 75% of my flywheel left.!

Its soo tight.! I wanna break it in now.!

RE: Hyper/Picco .28 Massive Issues
 

I am glad you got it to turn over..What time will you be at nad al sheba? I want to see the picco run.

RE: Hyper/Picco .28 Massive Issues
 

Uh honestely no idea

I got a few things to do in the morning. Probably in the afternoon.

Again not sure, I just might come in the morning.

But ill be doing the entire break in tomorrow, so I should be there for a good coupla hours.

RE: Hyper/Picco .28 Massive Issues
 

Well 4 3000mAH batteries later and no luck.

It started a few times but kept flaming out the second I lifted off the throttle. Anyone know the reason to this.?

I tried adjusting all the needles ( Idle, LSN, HSN ) and it was fine as long as you kept throttling it, but the second you let it go down a bit, no luck.

Im gonna try again during the week - Monday or Tuesday, and bought a gel cell today, and should be picking up another soon.

Anyone know why it kept flaming out.

RE: Hyper/Picco .28 Massive Issues
 

Just a question . Where are the alignment posts for you starter box? I you didnt have them installed when you were trying to start your motor that could be part of you problem.
Mike

RE: Hyper/Picco .28 Massive Issues
 

qaiz
next time you get it started try leaving your glo starter on the glow plug and actually run the truck on the ground with the glow starter still connected for maybe 1/2 a tank ,one of my piccos acted the same way and leaving the glow starter on really helped

RE: Hyper/Picco .28 Massive Issues
 

I had to raise the idle up a good amount. If it got anywhere near the proper idle RPM it would die just like you are saying. I did that for 5 tanks then it got better and I could lower the idle.

RE: Hyper/Picco .28 Massive Issues
 

I tried leaving the glow starter on the entire time, changed the plug twice, and still nothing. I messed around with my idle screw as much as I humanely could ( was in fear of severealy doing something wrong ) .

As for the alignmelt posts, im not using them, just the box itself. The motor started, quite a few times, but the minute I took it off the box and let off the throttle, it flamed out [&:]

Im just waiting on my gel cell to charge up completely, then Im gonna give it one last try for the day. Ill turn the Idle screw up a bit more, right now its screaming.

And I just signed up for a race on Thursday [&:], Lord knows how Im gonna make it for that.!

Thanks guys, will keep you posted within the hour on how it goes.

RE: Hyper/Picco .28 Massive Issues
 

i'd put the alignment post on. it will help you SOOOOOOOOOOO much!

RE: Hyper/Picco .28 Massive Issues
 

Sounds like have the needles set too rich.......as well no need to keep switching plugs....those plugs are very good and will last a very long time... If your drowning plugs you need to lean the motor down and by alot.... set the idle gap for 1 mm...then lean the motor down till it will run....

Best bet is to get the motor fired, hold the trigger half throttle, then have someone adjust the HSN till the motor starts to run clean,,,most likely 1/2-3/4 turn on the HSN from factory... then let the motor idle down..if it dies then you need to lean down the LSN..

sounds to me like you were to scared to lean the motor down.. If a motor will not idle its running way too rich. lean the LSN and the HSN to get it too run well.... you can always richen it back up once you get it running.. Factory settings mean nothing, do not be scared to lean em down........ usually i will go very lean to get a motor to start running, I will then hold the trigger open and richen the HSN till i can hear its rich.... same goes for the LSN, start her up lean ( race tune even) then just richen her up once its running..

DO not, and I repeat do not crank open your idle screw..that is not the answer, and will cause even further stalling if the LSN is too rich..set the gap for 1-1.2 mm tops..turn the LSN not the idle screw.... Do not be afraid of the needles, even adjust em while its running....

As well putting ARO into the motor will mess up the glowplug and make the motor a bear to start...ARO doesn't like burning nice..so if you were using ARO to lubricate the motor you were causing yourself much more grief then was needed..I never use ARO period !!!! the rustiest motors I have seen were the ones using ARO....you live in a desert ARO is not needed and is a waste of time !! light machine oil is much better for storage....

RE: Hyper/Picco .28 Massive Issues
 

race on thursday where???

RE: Hyper/Picco .28 Massive Issues
 

wait cancel that im not gonna be here then
