RE: Clark Spitfire begins
Brian, I have it just about ready to paint. I had some other full scale projects to do most of the winter and the flying weather has been nice the last few months but I'll get back on it real soon. The fuselage had a bad warp in it in the fin area and I had to cut it apart and reglass that area. Kind of annoying on a kit this expensive. I'll put it together this week and take some pictures of it on the gear. Don

Rick, It has been awile. I have some issues with the wing and I have almost decided to order a 1/4 scale Mick Reeves wing plan and short kit. Also this airplane is so big it is hard to handle. If I had it to do over again I probably would do the Taylor 83" Spit as it is a much better size. I will probably get more motivated as the weather gets colder. Don

RE: Clark Spitfire begins
Don, is your concern the supposed out of scale center wing shape as detailed earlier? If so, I'd love to see how you're going to go about adapting the fuse.

RE: Clark Spitfire begins
I ended up selling the project a couple years ago. I have been building full scale (a RV7, Backcountry Super Cub and another RV7 for a customer) and haven't done any R/C building or flying for several years now. However I just ordered a Flyzone FW 190 and have been eying a couple of my stash of kits. I would like to do a 1/5 scale or larger electric Spit, ME 109 or FW 190 in the future. Just cleaning up the model workroom this weekend. Don

RE: Clark Spitfire begins
I had been thinking about the Clark Spitfire motor, but ended up using something different, for my Easytiger Models Spitfire. If you are looking for a big spit that is cheap and flies well and not hard to assemble, check theirs out, it's 110". Mine is not electric, but they do have a video on youtube if it flying electric, it gets around great.
The electric system is impressive, I have seen it fly on other planes.

anyone have instructions on adjusting the carbs on the Clark "Merlin"? I've inherited the Spifire from my now deceased mentor . I believe he may have fiddled withe the carb adjustment. There's a 40 degree difference in head temps. I'd like to know atleast the starting points for the idle and high speed jets. Thanks Mark

Mark,
It sounds like you have it running, use a tach try to fiddle with the needle on the cold head. Watch and see if the RPM increases as you adjust the needle. when you get max RPM open it just a little bit from that setting just to make sure it isnt too lean. Then adjust the needle on the other cly and see if you can get more RPM and back an forth until you have max rpm, then see if the head temps are close. I don't believe 40 Fahrenheit is much of a difference. Setting mixture by using an IR temp gun on the cly isn't near as accurate as reading EGT with a temp probe.

Normally the rear carb will be a little richer to compensate for the hotter operating temp of the rear cylinder.
Normally, a standard Walbro carb will start and run with the low needle 1.25 turns out and the high speed at 1.5 turns. This should give you a rich mixture to start out with.

I just got a Clark Spitfire today. I bought it from a nice guy in Florida and he delivered it on his way north. Very cool! It needs a little rehabbing as it got slightly damaged on a hard landing by someone whose name we all know that I won't mention. Lol I'm very excited to get this lovely beast back in the air. I'm an electric guy (all of my 1/4 and 1/3rd scale WW1 models are electric) but I'm thinking something like a DA100i for power.
