You got that one running really nicely Mark. I’ve an FS-20 myself, but I haven’t figured out what to put it on yet.

Good morning Mark. Another good review. I would have loved to have owned a four stroke but alas no. I must say I am looking forward to seeing your next secret build. Take care. Terry

Hi Terry, thanks very much for the kind comment and your continued support, its greatly appreciated. Hahahaha, I think there are a couple of things to be done before that, but this engine is for my J60, but don't tell anyone!

@@MarkRobinson555 I wondered if it would be a Junior 60. So so looking forward to seeing your build on that one. The one thing I did change on my one was to raise the wing mounting dowels. To give the front dowel a stronger fixing I added 1/16 ply doublers to the front inside of the cockpit upright down to the mid longeron. Shaped to the side profile. Nice one.
@MarkRobinson555 Жыл бұрын
Thought you would like that, I do have another vintage build that you may like, which I will be posting first! Great idea about moving the dowels, will look much better. I am also considering reducing the dihedral a little, be interesting to know your thoughts on that one

@@MarkRobinson555 I very much agree with you. I reduced my models dihedral by I think by 1•5 inches either side. Although other's have got away with leaving it as stated on the plan. I built my J60 from the 1946 kit plan that had a narrower fuselage. Because my model is electric I did lengthen the nose by 1 inch. All I can say is it's a joy to build and so forgiving to fly.

Thanks Terry, good to hear your experience with the J60, particurally regarding the dihedral. The J60 plans I have are from Ben Buckle and I can't wait to build it, but there are a couple of other things I am currently working on and filming which I need to get sorted first, including a Tomboy Senior and a Ben Buckle Diamond Demon, I mention these as I know you like your vintage stuff!!

Please use the secure bolts on this engine ! Especially when tuning it... Mine is happy with a 10x6 APC.
@MarkRobinson555 Жыл бұрын
Yes, I think 10x6 will certainly be the better size, thanks for the confirmation

You sure that valve cover is plastic? I believe it's anodised aluminium I'll do a check on mine to see if you're right! Beautiful engines, o have the OS 20 and Asp 30 both run super smooth!!

If you are looking for the date of introduction of an OS Engine, you can show this official poster : www.os-engines.co.jp/english/timeline/O.S.1936_2020.pdf. FS30 was introduced in 1995.
