shaanaleem92 Posted January 19, 2014 Share Posted January 19, 2014 Sorry I meant 3 tanks yesterday, it's now done 7 in total still too early to be tuning it at 7 tanks Quote Link to comment Share on other sites More sharing options...
shaanaleem92 Posted January 19, 2014 Share Posted January 19, 2014 I am looking on ebay now but can't find much at the moment. It's left 7 fins. Would you recommend not using at the min? The outside temp is cool enough? Or will it not allow engine too cool enough not being full height. i would like to see pics of this damage Quote Link to comment Share on other sites More sharing options...
Jimboy2 Posted January 19, 2014 Author Share Posted January 19, 2014 still too early to be tuning it at 7 tanks All I have done it lean the high speed about 1/2 turn in total to allow it to get to full throttle. Before it sounded like it wanted to cut out when ever I did. I will be setting back to factory for next outing any way Quote Link to comment Share on other sites More sharing options...

I will be setting back to factory for next outing any way no dont bother ...that should be fine as long as it is still rich and running well enough to continue breaking in ... you don't need to re-set to factory again Quote Link to comment Share on other sites More sharing options...

Plenty of smoke coming out all through throttle range. I'm using Byron's Quote Link to comment Share on other sites More sharing options...

QRC Posted January 19, 2014 Share Posted January 19, 2014 That's a very clean amputation of fins, I would not run it without a whole cooling head. Reference cooling head just depends if you want a pucker one or copy/clone purple one. Quote Link to comment Share on other sites More sharing options...
QRC Posted January 19, 2014 Share Posted January 19, 2014 (edited) New pucker one from MS,http://www.modelsport.co.uk/hobao-mach-28-cylinder-head/rc-car-products/24412 Edited January 19, 2014 by QRC Quote Link to comment Share on other sites More sharing options...
Jimboy2 Posted January 19, 2014 Author Share Posted January 19, 2014 Yeah I was surprised it came off so cleanly. Was no bends in it or anything. I'm not really bothered what head I have as long as it fits as it should. What other ones will fit? A new one from modelsport is Quote Link to comment Share on other sites More sharing options...
DLD Posted January 19, 2014 Share Posted January 19, 2014 (edited) According to ModelSport, this one will fit, at Edited January 19, 2014 by DLD Quote Link to comment Share on other sites More sharing options...

Anthoop Posted January 19, 2014 Share Posted January 19, 2014 So long as you have the separate button the head from the .21 will fit. http://www.ebay.co.uk/itm/HOBAO-HYPER-7-21-3-port-cooling-head-and-screws-New-/261360214297?pt=UK_ToysGames_RadioControlled_JN&hash=item3cda486119 Quote Link to comment Share on other sites More sharing options...

But what button? Quote Link to comment Share on other sites More sharing options...
Anthoop Posted January 19, 2014 Share Posted January 19, 2014 The cooling head is a separate piece to the button...the button is what the glow plug screws into. Undo the four screws holding the (remainder) of the head on and you will see. Here are a couple of pics to show the .21 head and .28 head.....they are both the same other than the etching on top.

Jimboy2 Posted January 19, 2014 Author Share Posted January 19, 2014 Ah yes I see. So when I remove the four screws the glow plug bit will still be attached to the engine? That makes it a lot cheaper! Thanks will check tomorrow Quote Link to comment Share on other sites More sharing options...
Anthoop Posted January 19, 2014 Share Posted January 19, 2014 The four screws hold the head and the button to the engine casing. Once you remove the four screws the head will be loose but you may have to tug the button to release it....In your case you can leave the button as is and just pop a new head on.

Jimboy2 Posted January 20, 2014 Author Share Posted January 20, 2014 Excellent. Just ordered a .21 head. Only 12 Quote Link to comment Share on other sites More sharing options...
Jimboy2 Posted January 22, 2014 Author Share Posted January 22, 2014 Hi all. Another question for you all if you don't mind Servos. How do I get the throttle servo to its zero position. With the tx I can't see where the trim is set. How do I reset this. At a guess every time I switch it all on it goes to what it was set too last? So if I remove servo arm I may put it back in wrong place. So how do I get them set to how they were from factory with zero trim. Also car is all back together now ready for the weekend!

Anthoop Posted January 23, 2014 Share Posted January 23, 2014 I am not familiar with the TX you have but you say there is no zero setting for the trim? What you could do is remove the linkage and turn the Tx+Rx on...advance trim all the way and note position of arm (bit of tape to mark point), then retard all the way and mark....middle point between the two marks is the zero point....

To be honest as I was writing it I realised how easy it is to work out. I think my tx pauses at zero and then carries on apparently so will try that a bit late Quote Link to comment Share on other sites More sharing options...
shaanaleem92 Posted January 29, 2014 Share Posted January 29, 2014 your tx will show a green light once trim is set at zero.... so remove the servo arm.... re-set trim to zero therabouts....using the trim button on tx you will go past green either side of that its red...hard to explain but im sure you'll get it...not that hard in reality. re-attach servo arm...and bob's your uncle! (assuming your using the stock TX that came with the car from new) (it does kinda pause if i can remember correctly) 1 Quote Link to comment Share on other sites More sharing options...
HenryM Posted April 30, 2014 Share Posted April 30, 2014 Funny old thing these nitro cars ain't they! Just was t to get through 1st couple of tanks and then can breath a bit. When you hear it idling away nicely and then for no reason just start revving up its a scary thing ha Ive had my hyper 7 tq2 for a couple of weeks and i know what you mean; I used to jump out my skin when it suddenly revved lol Quote Link to comment Share on other sites More sharing options...
