Levanter Posted April 22, 2019 Share Posted April 22, 2019 I am gearing up to build a Veron Super Robot from the kit. It is 60" span and on the box says to use .25 - .40 two strokes. I had set aside an Irvine 36 Red Top but I am now think that I would like to use an OS FS 52 Surpass that is looking for a home. Which engine do you think would be a better match for the airframe (quite chunky) or wouldn't it really matter? A couple of years ago I built the Veron Robot and fitted an OS FS 26 Surpass but it has not flown yet. Levanter Quote Link to comment Share on other sites More sharing options...
GrahamWh Posted April 22, 2019 Share Posted April 22, 2019 I'd have thought a 36 size engine a bit small for a 60" trainer. Quote Link to comment Share on other sites More sharing options...

Don Fry Posted April 22, 2019 Share Posted April 22, 2019 If it's for use as a trainer, I'd use the Irvine, more expendable. If it's for its own sake, the OS52. Quote Link to comment Share on other sites More sharing options...
Peter Christy Posted April 22, 2019 Share Posted April 22, 2019 My Frog Jackdaw (60" span) flies very nicely on an ASP 30 FS, but I think the Super Robot is a bit chunkier and heavier. I suspect it will be well over powered with a 52 FS, but you can always throttle it back. Might end up a bit nose-heavy, though! The Irvine 36 is quite a pokey motor for its size, and is well able to swing a big prop - which would also help keep the noise down. Back in the day, we would have flown models of that size with a far less powerful Merco 35! My vote would be for the Irvine! BTW, I also have a Veron Robot which is nicely powered by an OS 20 2-stroke. I used to fly a Flair Attila on an OS20 FS, swinging a 10x5 prop, but I think it would have struggled with the heavier Robot. The 26 FS should be OK as long as it is lightly built. -- Pete Quote Link to comment Share on other sites More sharing options...

Ray Wood 4 Posted April 22, 2019 Share Posted April 22, 2019 Hi Tim, The Irvine 36 is a powerful motor, my 60" span Super 60 is fully acrobatic on an Irvine 25 😀 Regards Ray Quote Link to comment Share on other sites More sharing options...
PatMc Posted April 22, 2019 Share Posted April 22, 2019 Another vote for the Irvine. Quote Link to comment Share on other sites More sharing options...
Levanter Posted April 22, 2019 Author Share Posted April 22, 2019 Thank you everyone. Going on the consensus I will stay with the Irvine. I would rather not be overpowered and the 52 can wait for something more suitable. I did manage to shave off some weight on the Robot and their is more scope to do that on the Super. All I have to do now is find the safe place where I put the drawing and the instructions. Great advice as always. Levanter Quote Link to comment Share on other sites More sharing options...
gangster Posted April 22, 2019 Share Posted April 22, 2019 Back in the day I flew a super robot on an enya 40. It was a good match. Your Irvine probably has more poke than the old enya so I suspect will be perfect Quote Link to comment Share on other sites More sharing options...

Engines tried included a Yin Yan 15, PAW 19, Fox 15 & Enya 09. The Fox was a good power & weight match however the Enya was best overall being about the same weight & only slightly down on power in comparison but with more reliable throttle response. Later modified the model for electric with a 3s 2000 lipo & 1600kv inrunner turning out Ollie Tiger type power but since changed to a lower kv outrunner using a bigger dia prop for lower speed but better climb.

Levanter Posted April 23, 2019 Author Share Posted April 23, 2019 Lovely model PatMC Interesting how going electric tidies up the nose. Here is mine Following the Box Art which I don't normally do. I didn't have any white solatex so went for the linen. The OS 26 nestles in very well. I did thin down the nose cheeks and tapered them inwards in a curve to just leave a small radius outside the spinner. A cover over the fuel tank was about the only other mod.

FlyinBrian Posted April 25, 2019 Share Posted April 25, 2019 My original single channel Robot (c1967) was adequately powered by a 1.5 cc Frog diesel. Quote Link to comment Share on other sites More sharing options...
