Brian Dorricott 1 Posted December 3, 2017 Share Posted December 3, 2017 Anyone had a go at this month's Mini Blitz ? Not sure what electric power setup to use ? A 22mm motor will fit but not sure which one , the article mentions 150 watt but not which motor . I have some 1300mAh 3s batteries but not sure what to go for on motor and esc , as it's my first RCME plan build don't want to spend a lot in case I total it first time out , did I mention I have never flown a delta before ? Any suggestions welcome ! Quote Link to comment Share on other sites More sharing options...
Shed dweller Posted December 4, 2017 Share Posted December 4, 2017 I built a Mini Blitz this time last year from my stack of old free plans. It goes very well and i am happy to recommend it. I will post the vital statistics this evening when I get a chance, but from memory, it uses about 50W power from a 2S lipo. Low weight is very important!

Kevin Fairgrieve Posted December 6, 2017 Share Posted December 6, 2017 20+ years ago I built one of these. Well what I actually did was to enlarge it and strap a .25 2 stroke on the front of it. I had only been flying for a couple of years then and was to chicken to fly it. As far as I recall it only flew once in the hands of the club expert, a man who could fly anything. I think this kind of scared him. No idea what happened to it as it was so long ago. Any way back to the present. Going down the electric route with this one. Motor. **LINK** ESC. **LINK** Battery. **LINK** RX. **LINK** No idea if this set up is any good. I mainly fly I.C. but electric has its place in my fleet too.

Kevin Fairgrieve Posted December 10, 2017 Share Posted December 10, 2017 The build does not take long. Kev Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted December 10, 2017 Share Posted December 10, 2017 A splash of colour is all that is needed. Wings covered with film. Body sealed with PolyC. Early indications point to a slightly nose heavy beast. Kev Edited By Kevin Fairgrieve on 10/12/2017 21:44:51 Quote Link to comment Share on other sites More sharing options...
Nigel R Posted December 11, 2017 Share Posted December 11, 2017 Hi Kevin What prop are you fitting, and what sort of Watts does that setup consume? Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted December 11, 2017 Share Posted December 11, 2017 I have that exact electric set up in my spares box, perhaps I should build one? HK recommend a 7X4 on 3s. If I were to make a wild guess I would think about 170w, depending on the prop. That being the case it should go like a rocket!

Kevin Fairgrieve Posted December 11, 2017 Share Posted December 11, 2017 Yes that is a 7x4 on there at the moment. 3S 1000mHa Should go OK, although I confess to knowing very little about electric set ups. Kev Quote Link to comment Share on other sites More sharing options...
Nigel R Posted December 11, 2017 Share Posted December 11, 2017 "That being the case it should go like a rocket!" Isn't that the idea? Thanks Kevin. I have some 3S1000mahs and this years club build is a wing with about the same power requirement, so its nice to know a usable setup.

Piers Bowlan Posted December 11, 2017 Share Posted December 11, 2017 I tried a 7x5 APC prop and 1300mAh LiPo (didn't have a 1000mAh) and it was giving 13A and 144W which seemed pretty good. Your prop Kevin appears to have a broader chord than my APC so it may produce a tad more thrust, especially as my prop was wearing quite a large spinner. I am sure it will be more than adequate, the proof of the pudding etc.... . Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted December 11, 2017 Share Posted December 11, 2017 I will try to get it into the garden tomorrow and put it on my watt meter and get a few readings. The prop is a cheap HK one, so not probably as good as an APC. Kev Quote Link to comment Share on other sites More sharing options...

That is quite OK Kev, especially as I have to confess to knowing very little about IC set ups! Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted December 12, 2017 Share Posted December 12, 2017 Pics of my i/c version are already on the `new build` thread. Waiting for the weather to warm up and my courage to build up. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted December 12, 2017 Share Posted December 12, 2017 Called into work today due to staff shortage. Looks like no day off for me this week. Will check wattage drawn as soon as i am able and update accordingly. Kev Quote Link to comment Share on other sites More sharing options...
brfc7 Posted December 14, 2017 Share Posted December 14, 2017 Just got the magazine today and I'm going to build both the Mini and Micro and probably get the Micro in the air first. Baz Quote Link to comment Share on other sites More sharing options...

Kevin Fairgrieve Posted December 16, 2017 Share Posted December 16, 2017 I hope to do the maiden tomorrow. Weather permitting of course. Kev Quote Link to comment Share on other sites More sharing options...
brfc7 Posted December 16, 2017 Share Posted December 16, 2017 Forgot the wife was at work tonight, so back out came the balsa I cut out 2 fins and the way I've decided to do it is to put another rib in just far enough away from another one so I can slide fins in straight vertical. I'll probably cover the wing first then glue the fins in. I also cut out 2 fuz sides and dry fitted them. Baz Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted December 17, 2017 Share Posted December 17, 2017 Due to unforeseen circumstances (a hangover following works Xmas party) the maiden has been delayed. Kev Quote Link to comment Share on other sites More sharing options...
Rene Wallage Posted December 17, 2017 Share Posted December 17, 2017 Waiting with bated breath... Before I proceed I'd like to see how your power setup works... Quote Link to comment Share on other sites More sharing options...
Rene Wallage Posted December 18, 2017 Share Posted December 18, 2017 Has anybody made one with removable fins? Quote Link to comment Share on other sites More sharing options...
brfc7 Posted December 18, 2017 Share Posted December 18, 2017 The way I’ve made mine Rene with the extra rib, I could just slot the fins in as they are a tight push fit and I haven’t glued them in yet. I’m installing the fins without the stated angle, mine are straight vertical. Baz Edited By brfc7 on 18/12/2017 09:03:12 Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted December 19, 2017 Share Posted December 19, 2017 Maiden done A few clicks of right and a couple of up was all that was needed. Not ballistic but enough to fly nicely. I think an ASP prop would be better suited to this model. With my setup it was pulling 125 watts on a fresh battery, so that equates to about 12amps. With a 30 amp ESC there is plenty of room for experimentation. Kev Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted December 19, 2017 Share Posted December 19, 2017 Perhaps try an 8X4 prop Kevin if you are looking for a more spirited performance. Also a slightly larger capacity battery like my 1300mAh LiPo might give it a bit more grunt without adding too much weight. Like you say, plenty of room for experimentation.

john stones 1 - Moderator Posted December 19, 2017 Share Posted December 19, 2017 If the ASP's no good try an APC they're o.k. Kev Quote Link to comment Share on other sites More sharing options...
