I have made aluminium bushes to reduce prop hole diameter loads of times with no problems .Just make sure the fits are good .I wouldn’t heat things . The crank shaft between the prop driver and the thread is usually a bit bigger than the threaded bit .I make the bush to fit the unthreaded part .only

I had a saito 180 which I ran on laser fuel 10% oil with no problems

You would if your club had members who won’t secure the site .We have constant problems with gates left unlocked

A boyhood friend had one we used to fly it on the prom in Blackpool .Great fun

My thinking on this is the super sixty is a better trainer than a junior .it’s a a radio control design whereas the junior is really a free flight model .The frog jackdaw is also a good flier but I don’t think a kit is available

Super 60 is a much better flyer than a junior .It’s also possible to build one with ailerons which improves things further

Scalpel and blades I use no 11 .permagrit sanding blocks ,small clamps ,razor saw and miter box

It looks like a frese aileron (not sure of correct spelling) .When up aileron is used the bit at the bottom sticks out adding drag to counter the drag effect of the other aileron going down .It’s supposed to eliminate adverse aileron yaw .The way its drawn with a bent robart hinge won’t allow any upward travel .If I was building the model I wouldn’t bother with that method I’m not much concerned with scale detail I prefer a practical model

Try measuring static thrust using a spring balance attached to the tail group you should get about 4 kg

It is correct if counter intuitive .The molar mass of water is 18 the molar mass of oxygen is 32 and nitrogen is 28 so the water in the atmosphere dilutes its molar mass which reduces its density Alan

It is good but he has just put the price up by about 50%

There are milling slides available I have one I don’t use it’s made for a myford

I had one a few years ago it had a zenoah 45 which was more than enough .So your 35 will be fine .My wheel cowlings were a mess after a few flights too

I’ve got a quick change tool holder ,it’s worth it’s weight in gold well worth getting one

I enjoy watching you and William flying keep it up

You haven’t seen Bert fly one then !!

Hi Bert It looks like black mould on the covering .Try some dilute bleach but do a bit underneath to test the paint will put up with it

Hi Bert how many stamps have you got now ?

My one is standard I don’t have a cooling problem

Mine is my mums old wooden ironing board with a 3/4 ply top so when I want room in my workshop I can fold it up and put it to one side .Not good for hammering on though

Have a look at the carbon copy website

Carbon copy and 4max do carbon u/c

Hi Jon Dont use any organic solvent to remove paint or glue It makes absorption through the skin more likely .Soap and water is much safer Re smells from 2k ,it’s thinned with xylene and toluene and the other ingredient is a di alcohol which pongs so you are safe if you can’t smell anything

Try 4Max ,there servos are good and not a daft price

Hi Bert Are you doing it like the tiger moth ? Alan
