Daren Cogdon Posted September 24 Share Posted September 24 I've had one of these kits kicking around for at least 3 years - really think it's time I started the beast! Has anyone else built one? If so, what are your impressions of it? Quote Link to comment Share on other sites More sharing options...
payneib Posted September 24 Share Posted September 24 Easy build, easy flyer. It just slots together. Mine balanced perfectly on the spar with the recommended motor from 4max, with a 3s 1800mah battery. Don't think, "it's a warbird, keep the speed on" because it'll never come down. Just float it in like a trainer. There's no need to do any mods to the kit, just build it as is. 3 Quote Link to comment Share on other sites More sharing options...
Daren Cogdon Posted September 24 Author Share Posted September 24 Very nice. What did you use to cover/paint it? Quote Link to comment Share on other sites More sharing options...
payneib Posted September 24 Share Posted September 24 Dressmakers polyester and Ezedope. I just used coloured fabric on this one, but I painted both the 109 and Hurricane with acrylic rattle cans over the fabric. 4 Quote Link to comment Share on other sites More sharing options...

Daren Cogdon Posted September 28 Author Share Posted September 28 So there's all the bits (plus the extras that they brought out so you could turn it into a later-model Spit). Hopefully gonna make a start tonight....! 1 Quote Link to comment Share on other sites More sharing options...
Daren Cogdon Posted October 3 Author Share Posted October 3 Haven't managed to make a start on it yet, due to one thing or another. But hoping to do so over the weekend or beginning next week. Quote Link to comment Share on other sites More sharing options...

Daren Cogdon Posted October 21 Author Share Posted October 21 So, I've started to fit some of the electric components (after following the video), and I've had a few issues with the motor fit - namely the captive nuts falling out whenever I tried to attach the motor. When three out of four of them eventually fell out, I decided to go down a different route and attach a piece of spare plywood to the front firewall, and just use self-tapping screws to attach the motor (as I did for the FT Spitfires). Now, I was originally going to use a 1300kV motor that I have going spare but, when I add the extra piece of plywood to the mount, it hangs out of the front by about half an inch, and looks quite unsightly. I considered using a 1000kV motor instead, as it's shorter, but I'm not sure this is going to work for this model. Anyone? Quote Link to comment Share on other sites More sharing options...
Geoff S Posted October 21 Share Posted October 21 I always fit (and glue - epoxy) captive nuts to firewalls before they're installed. If you forget, then Modelfixings supply threaded insets that can be fitted from the front. Personally, I'm not too keen on using self tappers to mount motors. Can't you add the extra thickness to the back of the firewall? Or you could fit captive 'T' nuts to an extra firewall and fit that to the back. Even if the T nuts are loose as long as the bolts are in they can't fall out. The kv of a motor doesn't determine its power although more powerful motors tend to have lower kv because then larger propellers can be fitted without exceeding the motor's current rating. Provided your 1000 rpm/v motor has a suitable current rating it'll work fine with a slightly bigger prop (either length or pitch) 2 Quote Link to comment Share on other sites More sharing options...

If you can get the extra bit pf plywood off to get you back to square one, a piece of threaded rod can be used to pull the captive nuts up tight to the back of the firewall, at which points you can get a bolt with a nice big washer on it and tighten the captive nuts, drawing the tangs into the rear of the firewall, so that they are gripping to stay in place. If you are patient enough, you can put a dab of vaseline on the inside of the threads and a smear of 30 minute epoxy on the captive nut, before inserting them, so that they are well fixed. I've also had good success using the threaded inserts from RCWorld in lieu of captive nut for motor mounting. If you can't do that then using the lower kV motor ought not be a problem, if you can use a larger prop to get a similar current draw. Personally, once I get any larger than the wee 20g pole and stator motors I'm not keen on just using self tappers into the firewall. Quote Link to comment Share on other sites More sharing options...
Daren Cogdon Posted October 21 Author Share Posted October 21 Thanks for the suggestions. The model does have TWO firewalls in it, since there's an option to fit one or the other depending on the motor size you use (but I fitted them both to add a bit of strength to the front end). The plywood fortunately hasn't been attached yet, so I will see if I can try to get the captive nuts back in place without too much hassle before trying an alternative.

leccyflyer Posted October 21 Share Posted October 21 Here's the tool that I made to fit captive nuts, from a length of threaded pushrod. The bend lets you place the captive nut on the thread, after the rod is inserted through the hole from in front of the firewall. Quote Link to comment Share on other sites More sharing options...
