|Thread: What size battery|
Would a 4S LiFe be good? Might be a safer thing to leave attached to a starter and stored near the fuel in a flight box. I suppose nominal voltage at around 13.2 volts would be roughly the same as a 12v lead acid at full charge.

|Thread: Pete Lowe, RCM&E columnist|
Very sad, always enjoyed his columns.
|Thread: This quarter's BMFA news|
I think the mag is okay but needs to stay more with current issues. One channel radio sets and vintage rudder and elevator models can't appeal to that many people nowadays. Some coverage should be included, but in proportion to the number of readers who are into it. I also agree with an earlier comment that the classification numbers should be explained when there is an article on them - what is F1D or whatever? The text only gives me what sort of model is involved - powered acrobatic or a glider etc. It is nice to read something that is not plastered with ads though, and it is good that a wide range of stuff is in there. A survey to see what people are interested in might be good though so they can tweak it.
|Thread: Help Please RCV 58 Instructions|
Here's a link to another site's copy of the manual
|Thread: SLEC FUNFLY MOTOR|
A friend of mine fitted a Tornado Thumper V2 3548/05 to his electric funfly and it goes very well on this. Are you making the electric funfly or the I/c one with an electric conversion?
--sorry, I have just checked HK and I don't think they do this motor.

|Thread: Hobbyking have a sense of humour|
Includes "a Tourniquet (use this to stop the blood flow when amputating a limb)"
Handy I suppose if we want to start cutting each others arms or legs off. Can't say it happens much at our club! Wonder if they include a suitable saw.
A few plasters seems a sensible idea though.
|Thread: Making a fibreglass cowl look like metal|
Posted by Peter Miller on 08/03/2015 08:34:18:
Peter - is this stuff fuel proof do you know?
Trevor - that stuff looks excellent. I'll have to research what may fuel proof it. Shame it does not come in a spray can - I may have to find a friend with a spray set up. What fuel proofer did you use on Wilco Chrome spray? Did it affect the finish?
Thank you everyone for the replies.
|Thread: building surface suggestions?|
I use plywood, 18mm thick, about 12" wide by 50" long. The advantage is that once a wing is pinned on the board but not yet finished you can pick it up, prop it against a wall while you set another ply board on the table to do a bit of the fuselage, or the second wing etc. It's nice to be able to change from one bit to another and easy to do like this. 18mm seem to hold its shape well over this sort of length and width.
|Thread: Making a fibreglass cowl look like metal|
I have moulded an epoxy based fibreglass cowl for a biplane my son and I are making (used a modified saucepan for the mould!) but we want to make it look like a metal one.
What is the best way? I have been thinking about metallic chrome/silver paint with fuel proofer (for glow fuel) but wonder if chrome oracover could be made to curve around the front of the cowl. Any recommendations? Also has anyone used the chrome oracover and found how well it goes around curves?

|Thread: Are Turnigy lipos any good?|
I would not go for the nanotech 20 c range. In 20 c applications I have found that my 2200's and 2650's puffed quickly. I would only want 35c or above, and use them for 20c applications. I think the normal Turnigy's may be better.

|Thread: glow plug current (amps)|
2.5 Ah rather than mAh?
|Thread: Airtek Hobbies-Good service|
Ordered some stuff Sunday evening, got it Tuesday am - all good. Always been reliable for me, I have them in a "favourites" folder.
My only gripe would be that as with a lot of places, the minimum p+p is a few quid, but fine if buying £20 of goods or more. Ebay best if just getting one low value item as far and p+p goes I think.
|Thread: Bending exhaust header pipe|
Thanks Jim, fantastic.
It is steel ED. Thanks.
Jez - that's around £20 with postage and I don't think it will allow the muffler to clear the engine mount if taking the muffler vertically downwards. £20 is a lot to my 11 year old who I am building this with!
I am aware of thread **LINK** but do not want to learn silver soldering just for this job. Thanks.

I want to fit the exhaust of an ASP 61 four stroke into the cowl of a biplane.
The exhaust header pipe is not bent sufficiently to allow this. Is it possible to heat the pipe strongly (removed from the engine and muffler of course!) and carefully bend it further? It is made of steel rather than aluminium.
|Thread: thrust line for Bristol scout, 54" by David Womersley|
Thanks John, I take it AoA is angle of attack. I may go with the 4 degrees, but it is more than I have used in the past. May try 2 and add washers if need be.
Thanks PatMC and JH, 'tis a complicated thing to be sure!
It is RM161 from the myhobbystore plans. The ad on their site is wrong - it says the designer is a Martin Fardel, but it clearly says on the plan it is Womesley. Also if you search for it under "Bristol Scout" it won't come up - it's titled "Bristol Type D Scout" (!)
The span is 54", so I am not sure the scale is exactly 1:6 - David Hurrell did a 1:6 one but that had a smaller span (Traplet publications).
The RM161 design uses a simpler aerofoil which will be easier for me and my son - he is 11.
Getting there very slowly as it is hard to prise him away from the TV and computers!
Thanks John, lovely looking biplane. The biplane we are building is the type D biplane BEB.
