Forum members' new models: Let's see them.


Recommended Posts

Shorts Sperrin from the Chris Golds plan, 74" wingspan. 4 x 55mm Vasa fans, running on 6S, 53,000rpm producing over 800g of thrust each and using 450W. Successfully maidened today. Will take off from grass runway (not bowling green smooth) but would be better of tarmac. Will happily cruise around on 150W per fan so 9 minutes flights are possible.

 

The Sperrin was designed late 40s early 50s as a fallback in case the Vulcan, Valiant & Victor, all revolutionary designs failed to live up to expectations. The Sperrin was very much a conventional design, rounded rectangular fuselage, basic wing with the unusual (in hindsight) stacked engines rather than side by side. 2 prototypes were built and ended up being used as test beds for other engines and for flight research.

Very nice model Peter, i am just finishing off a Chris Golds KI-61 mini fun fighter, he seems to have been very prolific in his drawing of scale plans, is there a list somewhere of what is available of his designs? I enjoyed building this one and would like some more similar ones.

I believe that the description "prolific" is an understatement. I do not know if there is a single list, I have seen such a list requested on RC Groups to no avail. A lot of his stuff was in "Quiet & Electric Flight" and "RC Model World" which have ended up with Sarik Hobbies which is where I bought my plan and short kit from, but he also published plans in "Flying Scale Models" which are not available from Sarik, most notably an 84" Canberra for 2 x 90mm EDF. A lot of his prototypes ended up having posts written on RC Groups by his colleague Robert May. So you have to search around a bit.

Hi All,

Just finished my Flair Black Magic, covered in encapsulation/laminating film.

Powered by an SC 30fs, I still need to add 100g lead in the nose to balance it.

I bought the lit on a well know auction site and was listed as new, however, parts were missing which I replaced using the drawing and the bowden cables and I had to use snakes which is probably why I have to add the weight at the front. Note to self, check kits when bought and not leave them for years in the cupboard.

Looking forward to the maiden

I have had this model for a number of years, but yesterday was the day.

Maiden went well, a few clicks of down and right and big loops and rolls were the order of the day.

Here's my Eyelash.  Not exactly new, I built it in 1975(!) from a MAN article and plan, (which I still have) and flew it extensively then over the next few years in Bermuda.  Powered by a Cox TD.049, it was fast, with no throttle on the TD!  A miniature Pattern plane, it was a very small version of the .60 powered Eyeball, 0-0-0set up, exciting to fly.  I remember a 50 turn power on spin from a height that I could just see it (it's very small- good eyesight required!)

Anyway, we returned home, the Eyelash went into the loft, in lieu of other models, and I only brought it out a year ago, after a 20+ years period when I was too busy working to fly.  I now had entered the new mystic world of electric motors and lipos! 

So, on advice, the TD was hauled out, and replaced with a (Banggood) cheap and cheerful 2212 2200kv electric motor on a 1300mah 3s battery and a 6x4 prop.  Wingspan 38 1/4"  Area 215sq in  Weight 24oz.  Ace rigid foam wings, with fibreglass tape top and bottom.  Solarfilm finish

Well it flies as I remember it, with the added luxury of a throttle!  It's fast!  On flying it again, it still requires quick reflexes- and good eyesight, but it behaves perfectly, like the small pattern model that it is.

Successful maiden for my Dynam Hurricane, which I was quite impressed with, apart from the retracts - one of which stubborly kept dropping down/ No amount of cycling would cure the issue, which didn't help the smoothness of the flight. Then blow me, on landing that retract promptly collapsed and the model flipped. Only broke a wingtip, which is repaired now.

Well. a few minutes in the vice bending the leg back in spec and the retracts were working smoothly on the bench, then out at the field this morning they both refused to deploy, just whirred away with no movement. Think I'll whip them out and replace them with better quality E-Flite units.

Today was the first of three maidens of our clubs members build of the Extreme Flight E-Outlaw. I'll leave the background for the build thread, but needless to say its built for speed.

 

Vital statistics, old money, wingspan 36 inch, length 26 inch

AUW - 1.958 Kg

Static power - 2.086 Kw, 90.31 A

Prop - 9 x 9

Motor - Extreme Flight Xpwr T3520

Maiden needed a few clicks of up (schoolboy error as most delta's need a bit of reflex).

 

 

Second flight allowed the chance for it to stretch its legs where it gains speed though deception where you realize how quick its going by the size of the circuits it takes up.  

 

Please like and I'll crack on with the build log 😃

Finally got my Taylorcraft "Tumbling T-truck test flown.

 

It was a little strange at first with a tendency to need a ot of rudder to help a right turn. 

When I added considerably more aileron throw it could really be thrown round. No shots while aerobatting but here it is in Level flight.
