Phil 9 Posted May 7, 2017 Share Posted May 7, 2017 These must be as rare as hens teeth as I cant remember the last time I saw one at any club day. Just to reassure me they do exist please show them off here Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted May 7, 2017 Share Posted May 7, 2017 Oh Yes. I still fly my Grumpy Tigercub. One of the nicest and easietst and safest twins. The only problem is working out which engine has stopped AND THAT IS NT MY OPINION Two 15s and does it go Quote Link to comment Share on other sites More sharing options...

Robert Parker Posted May 7, 2017 Share Posted May 7, 2017 Hi Phil, Here are a couple of photos of my twins My TN Beaufighter as yet unflown. Powered by a pair of Irvine 0.46's An "Easi-Built" kit PBY Catalina, bit of a handful to fly slightly underpowered, Brushless upgrade total stab in the dark My TN 60" Wellington, not completed many successful flights Being a little of topic, my double twin own design Stirling.

Martin Harris - Moderator Posted May 7, 2017 Share Posted May 7, 2017 Sadly, my Ripmax Extra Slim Twin shuffled off (or should that read splattered into) this mortal coil a few years ago but I do have an Extra Slim kit with the necessary duplicate parts copied awaiting its turn in the build schedule to replace it - this time with a pair of OS 46FXs instead of the 40 FPs that replaced the SC25s which originally flew it quite well... I hope this intent qualifies me to post in this thread! These really are the ideal first twin - with the close coupled engines and airflow over each fin they handle single engine situations with ease and I would happily complete an aerobatic flight with an early engine cut, just for the fun of it. If anyone comes across an old stock kit I can highly commend it. Just contact me for details of how to configure the control surfaces as it caused me an awful lot of head scratching and has confused others in the past! I think its demise was due to an unnoticed inner engine cut during a low level flat spin - the only situation where an engine cut ever caught me out...

Paul Marsh Posted May 7, 2017 Share Posted May 7, 2017 I have about 20 twins. Such as P-82 Twin Mustang to Extra Slim twin. I got this last year for a good price. They don't make it anymore, but an ideal twin trainer. And Twin Otter, large scale, flies well.

Rob Fairweather 1 Posted May 7, 2017 Share Posted May 7, 2017 I think it was from a rival plans service, but back in about 86 I built a little TooCan ( Toucan, TooCan ? ) for a pair of 10FSRs. Brilliant little beast with a big fin. It went better on second build with larger props and a pair of 15s. Quote Link to comment Share on other sites More sharing options...

Simon Chaddock Posted May 8, 2017 Share Posted May 8, 2017 I have great admiration for those who fly twin (or more) IC. By comparison an electric twin is relatively safe. Of course if you put the motors in tandem and counter rotating it becomes even safer. Quote Link to comment Share on other sites More sharing options...

dave windymiller Posted May 8, 2017 Share Posted May 8, 2017 Dual ace 2X OS la40's Ripmax rapier clone (2 X sc52's). When one engine packs in (usually the back one as its a smaller tank) I can start to relax!

David Davis Posted May 9, 2017 Share Posted May 9, 2017 At the moment it's only the seed of an idea but I am dreaming of building Mike Booth's Bristol Blenheim. **LINK**The model has a 2159mm wingspan. The original flew on a pair of OS 40 FPs. I have three pairs of engines which I could use: two OS 48 Surpass; two HP VT 49s and two Laser 70s. Alternatively I could just buy a pair of modern 40 two-strokes. What would you recommend? Quote Link to comment Share on other sites More sharing options...
Jon H Posted May 9, 2017 Share Posted May 9, 2017 Its got to be a pair of 4 strokes David. The two lasers would be more than man enough I am sure. how heavy is the model supposed to be? As for me, I have had many twins over the years. Sadly no photos of the beaten up pilot twin ace I taught myself with, but I do have photos of my Ripmax harmony which had no less than 3 different pairs of engines in its life. It was retired as it frankly fell to bits after many years of thrashing. My galaxy twin scorpion was fun with a pair of 30 4 strokes but I sold it due to not having any space in the hangar. I don't have photos of my ASM Hercules either as I didn't keep it long. It flew well but was boring. My current mount is a hangar 9 pulse 125 modified to have a laser 70 on each wing. No decent photos, but you get the idea Quote Link to comment Share on other sites More sharing options...
Chris Freeman 3 Posted May 9, 2017 Share Posted May 9, 2017 I have had quite a few twins over the last 30years, electric has made it so much easier but nothing beats the challenge of getting glow motors to run well in a twin. Most of these aircraft were donated to the fire gods! I now have a hanger 9 B25 and am now busy fixing a unflown ESM B 25 that I bought after it fell from a ceiling.

Ace Posted May 9, 2017 Share Posted May 9, 2017 Lark 70 converted to a twin with LA40's. Took my A with this as it was the only serviceable aircraft I had on the day. Simulated dead stick resembled a lawn dart with a well timed flair - passed. Ace Quote Link to comment Share on other sites More sharing options...

The two lasers would be more than man enough I am sure. how heavy is the model supposed to be?... I don't know how heavy the model was Jonathan. I used to have the magazine article on the Blenheim but with two house moves that seems to have gone missing. You're right of course, two Laser 70s would fly it easily but it would need a pretty substantial undercarriage as well, regardless of the engine chosen. Must stop skiving!

Geoff S Posted May 9, 2017 Share Posted May 9, 2017 Here' a couple I took of a friend's YT P38 a few years ago. A pair of RCV 90 engines IIRC. ... and now as a single! I'd taken a few pictures and complimented him on an unusual manoeuvre quite far out - actually is was a skilful recovery from an engine dead stick! Perhaps he should have opted for Laser engines (before Jon Harper chimes in ) Geoff Edited By Geoff Sleath on 09/05/2017 16:38:27 Quote Link to comment Share on other sites More sharing options...
gangster Posted May 9, 2017 Share Posted May 9, 2017 Just rigging a Ripmax Harmony that I have been given complete with two sc40s I am wondering about batterys. The previous owner seems to have used one battery for all servos including the retracts. In theory this should be fine but if there is no bind on the retracts. What are the forumites thoughts on the rx battery/batteries for this set up Quote Link to comment Share on other sites More sharing options...
