Richard Wood Posted February 15, 2016 Share Posted February 15, 2016 As the lads say - leave enough wiggle room up front to enable the motor to be removed & adjusted easily. Good access to engine & silencer mounting bolts & carb adjustments makes life more pleasant. Quote Link to comment Share on other sites More sharing options...

Richard Wood Posted February 15, 2016 Share Posted February 15, 2016 There used to be a GRP cowl for the bullet, might be worth trying to track one down. Quote Link to comment Share on other sites More sharing options...
megapixelimages. Posted November 4, 2017 Share Posted November 4, 2017 Hi Any one have wing tip profile and wing plan profile for the Crescent Bullet. Thanks Quote Link to comment Share on other sites More sharing options...
Chris Berry Posted April 15, 2020 Share Posted April 15, 2020 Hi folks. Just starting to fit an engine to my Bullet after about a month of building. How have most people held the engine to the mount? It's a built in cowl, can only get the mount on without the engine and hard to get nuts on the back of bolts to hold engine to mount. Self tapping screws are an option but I've never been over keen on them. Cheers Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted April 15, 2020 Share Posted April 15, 2020 Chris, look three posts up from yours, nutplates screwed to the back of the bearer. Alternately I used to drill and tap the bearers. As long as you don't keep swapping engines this works on up to 90s. Quote Link to comment Share on other sites More sharing options...

So essentially captive nuts in on form or another in/on the nylon mount, job done? I have seen this used before but I've never done it myself. I'll give it a go.

Ian Southerton 1 Posted April 16, 2020 Share Posted April 16, 2020 From memory, I used a thin scrap of steel from somewhere, cleaned it up and soldered it using electrical solder that contains flux, and heated it all with a blow torch. I found the 10x6 prop with a 36 size motor a bit under powered. I hadn't been flying too long, so it was probably just me! I sold it not long after building it as I turned to the dark side flying helicopters!! Ian Quote Link to comment Share on other sites More sharing options...
Richard Wood Posted April 16, 2020 Share Posted April 16, 2020 Chris if you're using a SLEC round mount the tapered beams will make the captive nut arrangement difficult. Self tappers into this type of mount is generally very secure on a 40. Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted April 16, 2020 Share Posted April 16, 2020 hello chris,i would def consider the self tappers...I've used them on all sizes of ic motors and nylon mounts...no probs...and on a model like the bullet if you bolt the motor its awkward to get it back out and in again... ken anderson...ne..1...s/tappers dept.

Nigel R Posted April 16, 2020 Share Posted April 16, 2020 Another vote for self tappers from me, the nylon mount will grip them pretty tight once they're done up. Quote Link to comment Share on other sites More sharing options...
Chris Berry Posted April 16, 2020 Share Posted April 16, 2020 Thanks folks. I've used self tappers in the past with no problems to be fair but I've never been over keen. I'm used to 60cc stuff, which is belt and braces. I'll go with self tappers. Cheers Quote Link to comment Share on other sites More sharing options...
