Afternoon All,   I am hoping someone will be able to help.  A mate at the local club has bought himself a Super Air and is part way through building and come to install his Irvine 53.  The instructions do not specify a dimension from the firewall bulkhead to the drive washer of the engine.    Would anyone be able to advise?   Many thanks, Nick

Thanks for the helpful tips and advise.  Bearing puller ordered and in the post and I will look at renewing the prop driver and collet.   The good news is the crack doesn't seem to be bent, so I am hoping realigning of the bearings will be all that is required.   Nick

Hi Martin,   Sounds like you understand the problem and have better knowledge of the internals than myself.  Without a puller to remove the prop driver I am unable to investigate further myself.   The engine have been running fine but last involved in a mid-air and a subsequent impact with mother earth.  On initial inspection all seems ok.  This being the first time I have tighten a prop on it following the incident and now I find it binding on the case.   I noted that the shoulder on the crank shaft appears to be forward of the prop driver, by a very small amount.  Perhaps it has always been like this,who knows.   Would replacing the prop driver and split collet perhaps reset the horizontal position of the prop drive?   Nick  

Afternoon All,   Merry Christmas and all that good stuff.....   I am putting together my new xmas kit and come to install my trusty old Irvine 53 when I noticed the prop drive has moved back when I came to tighten the prop nut. On closer inspection I can see the harden insert inside the prop driver is split.   I am searching various websites for spare parts and I now understand there are several versions of the Irvine 53 and this part differs be the versions.  Would anyone be able to confirm the version number I have or the part number?   I believe the alternative prop driver employs a flat on the crank shaft to drive the prop driver.  I assume the model I have uses other means and this hardened insert.    I would be pleased of anyone can shed some light on this!   Kr, Nick

Morning All,   Excellent feedback.  Very helpful.  Thanks for that.  I will be contacting HH shortly.   Quality service support is hard to find these days, support like this is rare!   Kr Nick

I have already tired.   No proof of purchase, no support.  Understandable, but who keeps receipts for 12 months?  Don't tell me, you all do!  More fool me.....   I will contact the shop and see if they will offer proof of purchase to help me in getting Horizon to support.   Thanks, Nick    

Evening Timbo.  I agree, never had a problem with the AR500 before in the 2 models I have.  It is something with this model that has now resulted in 1 x AR500 not working altogether (I am looking for the proof of purchase so I can go back to Horizon) and this AR500 to now play up.   I have tried all possible combinations of battery, harness, servo, Tx etc.  There appears to be no common factor.   I bind as usual, bind plug in, Rx power on, Tx power on whilst holding bind switch, await solid light on Rx, check servo movement.  I then either unplug the bind then power off the Rx or power off Rx then unplug bind, neither changes the result.   Could a long period of not being used somehow damage the Rx?  Does it have a memory that could be damaged if not powered up often?  Or perhaps damaged if suffering a short across a servo or such like?   Nick

No joy, every order of bind, switch off and unplug has been tried.  I am running out of alternatives.   The Rx worked fine for 6 months.  It has been sitting for perhaps 6 months unused.  Could that have damaged the Rx?    

Evening all,   I am hoping for some guidance from those with more Spek experience.   I have a model that has been sat on the shelf a while but when I came to use it, it struggled to maintain bind.  It will bind fine, connection is quick.  Switch off Rx and Tx and remove the bind plug and then switch back on and then nothing, no bind.   I have eleminated all connected servos, switch harness, Tx etc, nothing seems to effect this behaviour.  Even completely disconnected from all servos it still looses bind after being switched off and back on.   Can anyone offer help?   Many thanks, Nick  

Photos arrived.  Very nice.   Are all three models still available?     Thanks, Nick Edited By Nicholas Kay on 20/11/2009 16:05:02 Edited By Nicholas Kay on 20/11/2009 16:11:36

Hi Phil,   Thanks for the interest.  I will consider the options, and perhaps what is remaining given the popularity of the posting....   I will PM with my details so you could post a few photos?   Many thanks, Nick

Hi All,   I am still looking.  Phil never got back in touch.   Nick

Hi Phil, Only just received notification of your posting.  Great news.   I am interested.  Please email me directly with you details and location, any photos too.   Many thanks, look forward to hearing from you soon.   Nick  Edited By Timbo - Moderator on 05/10/2009 21:34:28

Looking to increase my prop from a 12 x 6 to 12.5 x 6 and maintain some scale appearance.  Bought the larger prop only to find the hole is 5/16" not a 1/4".   I have looked around for a tube 1/4" ID 5/16" OD, but nothing on the shop sites I can find.   Any suggestions?   Nick

Evening All,   Recently picked up a flasher 450 kit and enjoying the finishing off with radio installation.  New to rotary wing I am keen to get advice when I have a problem.   Following the instructions would have you install the rear of the 3 swash plate servos 'with the output to the rear of the helicopter'.  Doing so I have an interference with the vertical link and the anti rotation bracket.  Turning the servo around, with the servo output to the front is fine but obviously puts the vertical link at an angel and thus would slightly change the geometry in comparison with the 2 forward links.   This is further confused as the instruction further on show this output forward orientation and the angled link, suggesting it was at sometime acceptable.   Does anyone have the ARTF 450 who could confirm the rear servo orientation?  And if so how they over came the interference with the anti rotation bracket.   Also, would anyone be able to confirm if the slight change in geometry of the inclined link would have any significant impact?  I assume it would have a tendancy to more backward as collective is increased due to the differencial in link movement, all be it slight.   Many thanks, Nick
