Biggles' Elder Brother - Moderator Posted June 15, 2011 Share Posted June 15, 2011 That was close Stephen - still as Tim said could have been a lot worse. This weekend for a maiden do we think? Weather permitting? BEB Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted June 16, 2011 Share Posted June 16, 2011 I'm fine now thanks David....last week I suffered a small whiplash injury to my kneck after stupidly walking into the shed door frame rather hard Small cut on head, but boy was my kneck bad for a few days!

Biggles' Elder Brother - Moderator Posted June 16, 2011 Share Posted June 16, 2011 Its really annoying the way those door frames step out and hit you like that - you'd think someone would do something about them Seriously glad you're getting over it - I know it can be very painful. Sunday - eh? Well I'll be keeping my fingers crossed for you Stephen and waiting for news! BEB Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted June 16, 2011 Share Posted June 16, 2011 Ah, saw 'whiplash' and assumed you'd been playing bumper cars - ouch, well you've got to remember you can't go head butting sheds now at your age Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 16, 2011 Share Posted June 16, 2011 I blame the hat that the missus makes me wear in the sun ( bless her ).It has a rim all around, and definately reduces one's field of vision....especially in an upward direction!Having said that, without the hat - the cut would have been a lot worse I fear .

Stephen Grigg Posted July 4, 2011 Author Share Posted July 4, 2011 This weekend was perfect for the zlin 50 to have its maiden and the second one flies just as superbly as the first.Ive made a few mods on the way,the only problem is the pants keep coming loose.

Artto Ilmanen Posted July 16, 2011 Share Posted July 16, 2011 Anyone using a Saito or Laser engine? rgds Artto Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted July 19, 2011 Author Share Posted July 19, 2011 I had to buy a new engine because I lost the silencer in the first ones crash .The first engine did feel to me like it changed in power but tuning sorted it out.Ive had no problems with the new motor an SC 91 2 strok so far.Mind you Ive had a nuber of dramas lately life wise and last went to the fiels early British GP morning,lost my old Wot 4 ,and its gone down in horrendous under growth and Ive not yet found it.I tried to get my bearings again yesterday and the only thing I found was a rather large adder,How can I find an adder curled up but not my model.Havent had time to fly lately,and my truck is full of work stuff I cant park anywhere at the moment.We are noise testing all the models at present which is also disruting things and upsetting members whose models fail.

Artto Ilmanen Posted July 29, 2011 Share Posted July 29, 2011 Hello all, It seems the engine sits to the right off centre,when looking from the front? (Saito 125) Anyone else having noticed the same? Maybe added side thrust is needed..I don't know. Any hints? / suggestions? rgds artto Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted July 29, 2011 Author Share Posted July 29, 2011 Yes Arto I agree and have added side thrust,my first model did pull fairly sharp left and I spent quite a time practising take offs to acclimatise myself.I havent taken off yet with my 2nd Zlin,Ive flown it but with a collegue by my side.Latest cicumstances have prevented me from flying the Zlin lately,but I will have it at the scale meet in August,complete with ite ready to break off aeriel and "gun" hopefully still attached Quote Link to comment Share on other sites More sharing options...
Artto Ilmanen Posted July 30, 2011 Share Posted July 30, 2011 Thanks Stephen, Thank you for your comment. I think I will add some side thurst, too. I'm sorry to hear about your lost of the Wot 4 and other circumstances that haven't allowed you go flying.. artto Edited By Artto Ilmanen on 30/07/2011 05:45:50 Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted July 30, 2011 Author Share Posted July 30, 2011 Im hoping to fly tomorrow,lots of models ready but very little time Quote Link to comment Share on other sites More sharing options...
Artto Ilmanen Posted July 30, 2011 Share Posted July 30, 2011 I think there plenty of us who want to read more on how your 2nd Zlin flies..btw did your first Zlin pull left only at the take of or in the air as well? I hope you'll have your "quality time" and manage to go flying.. Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted July 30, 2011 Share Posted July 30, 2011 Had 108 fitted and no such problems she does not pull. To either side any more than any other aircraft on take off, use your rudder Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted July 31, 2011 Author Share Posted July 31, 2011 Thats my problem Lee,my left hand is hamfited with rudder control so I snake down the styrip.Im practising hard and hope to sort myself out eventually.Im resting at the moment and going back to basics but will soon be trying again Quote Link to comment Share on other sites More sharing options...
Artto Ilmanen Posted August 3, 2011 Share Posted August 3, 2011 Lee and Stephen, How did the cowling fitted in your models? In my case the engine sits to the right off centre in the extent the spinner won't sit in the centre of the cowling either?? Did you encountered the same? If yes, what was your solution? thanks in advance, artto Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 3, 2011 Share Posted August 3, 2011 Hi Stephen eventually people find out the rudder is one of the most important surfaces of them all, try this it might help.Get a quiet day with no one around and just racy around do dummy take of runs with much lower power, up and down the strip and do it continuously for a full tank, this will get you really used to the rudder effect and how the model reacts on the ground practice just squeezing the rudder to hold a straight line down the strip, as for engine alignment if you are putting some right thrust in the engine then you have to offset the engine to the left on the firewall so that the prop exits centrally I fitted mine with no additional side thrust and had no problems Quote Link to comment Share on other sites More sharing options...

This is confusing as this is what I'm doing yet the prop doesn't exit centrally... Or, did you twist or turn the cowling to make the prop exit centrally? (sorry if this sounds insisting just want to make it clear for myself..) artto Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 3, 2011 Share Posted August 3, 2011 Hi Artto, firstly i ignore the fixing locations as suggested by the kit, i mark the centerline of the firewall vertically and horizontally, then i mount the engine on the mount making sure the prop driver is the prescribed distance from the firewall, then i (with the cowling roughly fitted line up the engine with the centerlines marked and the center of the cowl exit, its a tough thing to get right first time!!

Hi Lee, Thanks for the hint I guess I can act accordingly next time. In this case it's too late, I'm afraid. I used the kit instructions and drilled the bolt holes accordingly, etc. So maybe all I can do is add a tiny amount of side thrust to help the prop exit more centrally and rotate the cowling just a little, if necessary. artto Quote Link to comment Share on other sites More sharing options...
