taff74 Posted April 23, 2010 Share Posted April 23, 2010 Does anyone know the factory settings for the Hobao Hyper 7 .21 engine as I keep on fiddling with them and they are all messed up. I would like the Idle setting, High speed needle, Low speed needle. Thanks Quote Link to comment Share on other sites More sharing options...
Sphinx Posted April 23, 2010 Share Posted April 23, 2010 (edited) Hi mate have a look through this http://www.msuk-foru...showtopic=70534 There is a list of what people have put, you should find a Hyper 7 in there somewhere. EDIT: You have put in the wrong thread section you want General - Nirto, not Petrol hehe Gav Edited April 23, 2010 by Sphinx Quote Link to comment Share on other sites More sharing options...
taff74 Posted April 23, 2010 Author Share Posted April 23, 2010 Thanks for the reply, I have already been on that page mate and i couldnt seem to find the idle factory setting and thanks for noting out the General > Petrol. Silly mistake Quote Link to comment Share on other sites More sharing options...
Sphinx Posted April 23, 2010 Share Posted April 23, 2010 What hyper engine do you have mate? Is this not it ? Ofna/Hyper .21 engine Set the master needle IN until stops, then turn OUT 4.5 to 5 turns. Setting for the black low end needle is OUT 3.5 turns out from flush. Setting brass head mid range needle, should always be flush to the case.

Indie Posted April 23, 2010 Share Posted April 23, 2010 Just to let you know chap, a Hyper 7 is a NITRO engine, you'll need to use NITRO fuel. Easier to search the Nitro section for the right answers and also it might be worth checking out the newb guides linked Quote Link to comment Share on other sites More sharing options...
fraggs Posted April 23, 2010 Share Posted April 23, 2010 What hyper engine do you have mate? Is this not it ? Gav some of the hyper engines(turbo ect) the LSN is 3.5 turns out from minimal contact closing off the fuel supply nozzle ( minimal contact with brass screw that is flush on opposite side of carb the SFN (supply fuel nozzle)) Sorry if this causes any confusion, If you do 3.5 turns out from flush the LSN could be too rich to start with (not a bad thing I know) Really need to confirm the type of engine to have correct settings, It took me a while to find the correct factory settings for my Hyper .21 as there are 2 or 3 different ones 1 Quote Link to comment Share on other sites More sharing options...
taff74 Posted April 23, 2010 Author Share Posted April 23, 2010 (edited) Thanks for all your help, I've had a look on http://www.hobao-racing.com/engines-products.php?id=3 and i've found out that my engine is a just a normal Hyper .21, if you click on the url it is the top one on there Edited April 23, 2010 by taff74 Quote Link to comment Share on other sites More sharing options...
Bigjimknickers Posted April 2, 2013 Share Posted April 2, 2013 some of the hyper engines(turbo ect) the LSN is 3.5 turns out from minimal contact closing off the fuel supply nozzle ( minimal contact with brass screw that is flush on opposite side of carb the SFN (supply fuel nozzle)) Sorry if this causes any confusion, If you do 3.5 turns out from flush the LSN could be too rich to start with (not a bad thing I know) Really need to confirm the type of engine to have correct settings, It took me a while to find the correct factory settings for my Hyper .21 as there are 2 or 3 different ones This is very confusing, I have the hyper .21 turbo engine & I read that the LSN was 3.5 from flush! Well this was hanging out almost so I take it the turbo is 3.5 from minimal contact? & HSN is 3 turns out? Quote Link to comment Share on other sites More sharing options...
Joshyjol Posted April 2, 2013 Share Posted April 2, 2013 I recently set mine back to factory and I didn't 3.5 turns out on the LSN from screwed in to the bottom but it was a pig and wouldn't have any of it! Did it from 3.5 turns from flush and it was fine and fired up and ran no problems (very rich though) started leaning it out on Sunday but my savox throttle servo decide to set on fire!!!

Anthoop Posted April 2, 2013 Share Posted April 2, 2013 This is very confusing, I have the hyper .21 turbo engine & I read that the LSN was 3.5 from flush! Well this was hanging out almost so I take it the turbo is 3.5 from minimal contact? & HSN is 3 turns out? I did some testing and found some basic settings that will work to get it started...every Hyper .21 I know of will work with these settings (providing everything else is in the ballpark of course). Slide gap- 1mm max. LSN- 0.5mm out from flush. HSN- 3-3.5 turns. Once it has started get it warmed up (few minutes) and start by tuning the HSN so it performs correctly when the throttle is fully open...then move onto tuning the LSN by letting it stand then accelerate....if at the end of the tuning if the idle speed is too high/low then adjust it with the idle screw. If you are still having trouble getting the engine started with those settings then maybe we should start looking for other reasons. 1 Quote Link to comment Share on other sites More sharing options...
Bigjimknickers Posted April 2, 2013 Share Posted April 2, 2013 I totally agree, I had mine totally wrong I had 5 turns out on the HSN & 3.5 ftom flush with the LSN, like I said mine is a hyper turbo so I just got back from the skate park where I tried HSN 3 from fully in LSN 3.5 ftom fully in. Since I've had it, I've struggled to run it, and bugger me it ran! Straight away, plenty of smoke so not too lean & starting straight away & ticking over for about 15/20 seconds. I must admit its very stressful keeping two running, but wow, great fun, we were doing some jumps up the skate ramps me & my son with his hyper.

Bigjimknickers Posted April 2, 2013 Share Posted April 2, 2013 So if I bang the throttle flat out & it accelerates, then bogs down (my sons ) what do I do to the LSN? Quote Link to comment Share on other sites More sharing options...
Anthoop Posted April 2, 2013 Share Posted April 2, 2013 Could be either....that is why I always suggest to set the HSN for fully open throttle first...after warming it..and tune it on flat ground....if you do not follow the instructions things can go wrong.

Bigjimknickers Posted April 2, 2013 Share Posted April 2, 2013 I'll play again tomorrow, it's hard to tune 2x at a time!! Quote Link to comment Share on other sites More sharing options...
Anthoop Posted April 2, 2013 Share Posted April 2, 2013 I did suggest trying to concentrate on one at a time to help you get a better feel for things before eh? Good luck. Quote Link to comment Share on other sites More sharing options...

Could'nt start the damn thing until i used the same settings and now it starts after the 3rd or 4th pull Quote Link to comment Share on other sites More sharing options...
Bigjimknickers Posted April 6, 2013 Share Posted April 6, 2013 Just did some work for a mate of mine, Darren Johnson, he's got (or had) the track record for aldeshot track & a couple of championships, and he tuned both mine & my sons hypers! Really looking forward to a bash tomorrow now! Quote Link to comment Share on other sites More sharing options...

Bigjimknickers Posted April 8, 2013 Share Posted April 8, 2013 Sounds good...did he show you what he did and why? Yep, started them up, showed him my way of doing it, then once warmed he was revving the car listening to the revs & lowered the LSN til it revved cleanly with no bogging after ticking over for a few seconds then he countered it with the tickover adjustment as the revs increased as he leaned the LSN. I know the exact theory of doing all that its simply he's got to be better at it being an ex champion racer. Quote Link to comment Share on other sites More sharing options...
