Thread: 4 stroke tuning

Thanks very much Jon. I'll try the plug route first and see how it goes.

Regards, Richard

I am using Laser 5 fuel with a Super cat 4 plug and a 16 x 8 prop - not sure about the latter number tho. The mid point of the tank is in line with the carb. Not sure about valve clearances, how do you check that?

Hi Jon,

I hope that this thread is still visible - I found your clip very helpful in tuning my 155. However, I seem to be able to only get the top end to circa 7900 and the bottom to 2200. At both points, it flickers, so at the top it ranges from 6900 to 7900 and at the bottom, say, 2100 to 2400. Do you have any thoughts as to why.

FYI, the engine is in the plane - not on the bench, if that matters.

Regards, Richard

Thread: RAF's Finest Biplane? Hawker Fury MkI

Hi chaps, my Fury is just about finished. The CoG is more or less as per the plan. It weighs about 9 lbs with an OS 95 up front - any comments on this? I know that the tailplane should be chequered, but I've had enough - maybe do it later! Richarddsc_0336.jpg

Hi Ernie, luckily for me I am retired and my SWIMBO is very understanding!

Regarding metal for the fuselage, I used Metalcoat from Mick Reeves. Frankly, I am not happy with the result, I should have used some sort of balsa hardener beforehand as any pressure applied in the process results in dents in the balsa.

Chris, Danny, many thanks for your comments. Richard

Shame it's gone so quiet here - I am nearly there. Excuse the blue solartex, it was all I could source. Soon to spray.

Stuart, Danny,

For the record, I used the same approach for securing the ailerons and used some epoxy to tack the carbon rods (about 1.2mm - hope not too thin?) to S2 using a V grove. They seem OK. Am glad that I am not alone!

Hi Danny,

It's good to have you back.

Changing the subject from the above somewhat, I have been trying to decide how to proceed with making the fairing for the oleo legs and have bought foam from Bluefoam. Having not worked with the material before, can you suggest how best to shape it and whether you would agree with Bluefoam (when i spoke with them) that it can be covered with glass?

Alternatively, I would guess at shaping with block balsa - what would be your preference?

Regards, Richard

Many thanks Andy.

Hi Andy, regarding the mark (and servo positioning) you have made for the servo / throttle linkage through the firewall, am I right in assuming that you will be fitting a Laser engine and if so will that mark line up with the throttle connection on the engine itself? Are you planning on a Laser 80?

Thanks, Richard

Well I actually started the fuselage over a year ago, so it's been pretty slow. However it's kept me occupied and off the streets!

Thanks Colin. Should have looked at threads before posting

As very much a follower of all you chaps, here is my effort so far. I have just realised that the tops of the cabane struts are bent backwards, as well as vertical - that will test my wire bending skills somewhat.

Regarding the U/C, does anyone have thoughts on the merits or otherwise of installing sprung oleo legs and if so, where can suitable ones be sourced?

Graham,

I was interested in your last post as it related to the single carbon rod you used for the aileron hinges. Question - how did you insert the rod through the shaped front edge of the aileron. Did you somehow insert into the balsa or cut a strip/channel? A photo would be great.

That settles it. I'll pass on the carbon rods. Thanks Danny

Thanks Danny. I'll sleep on it. Just to be clear, my webs are not like Andy's - they are immediately behind the spars, not in between. Richard

Hi Danny, clever stuff. I'll get some Cad s/w. On another point, I have made both upper and lower wings with hard balsa spars and inserted vertical grain webbing between them. I happen to have some 1.2mm carbon rods and was thinking that it might strengthen the structure if I inserted them on top of the spars, but underneath the capping strips. What do you think? Richard
