Hi all,

Thanks for posting this! This is my plane in the above post. It was an absolute joy to fly and looked fantastic in the air. The 105" wingspan made it a very majestic sight. It flys very much like the real thing... have to turn it with the rudder, then some elevator and opposite aileron due to the very high drag, lack of differential ailerons etc.

I've just joined the forum and I cant believe I had not discovered it before now. It looks great and I look forward to contributing in the future.

I'm also building a 1/5 scale JN-4 from a Proctor kit, and also waiting on a 1/4 scale DR-1 which I'm very excited about!

Cheers,
Colin

Welcome to the forum from one of the old lags! Do you mix aileron and rudder when you fly her? If so, via a mixing channel (if so what %?) or manually. Do you get much adverse yaw?

Thanks for the welcome!

Yes, lots of adverse yaw. No, I don't use mixes for this primarily because if flys best when you lead with the rudder then add opposite aileron to manage the roll rate. You cant really do that with a mix. Also, real J-1 pilots didn't have mixes, so it kind of feels more authentic to fly it the way they had to.... it certainly adds to my respect for their flying. I get to do it from the safety of terra firma!!

Fair enough - always go with what works for you is what I say.

I'm no master RC pilot by any means, and this is my first WW1 model that has reached flying stage, so it was a bit of a case of working it out as I went. I was nervous as anything on the first flight but gradually getting the hang of it. Am always happy to listen to advice from those more experienced than me!

welcome, to the forum. What engine do you have? Is that an inline 4 cyc, 4 cylinder?

Hi... yes, it is an OS IL-300 engine, which is a 4 stroke 300 size inline 4 cyl glow engine. I also use a South Hertz models onboard glow which regulates glow to each plug individually based on the temperature of the glow plug.... very neat, and very reliable.

I chose this engine as it looks very close to the original Hall-Scott inline 4 the J-1 was fitted with, exposed rockers and all. Fitting it required quite a bit of surgery on the cowl and engine bay as the "recommended" engine is a 120 size 4 stroke. As a result the model has excess power available, but you can fly it comfortably and with scale like performance on 1/4 to 1/2 throttle. It is also perfect for the C of G - no extra weight was needed.

Cheers,
Colin

Lovely Model there Colin.
I was going to ask what you had turning the prop... That In line sounds great.

Cheers,

Hugh
