I would have suggested something like this
'cos I thought it was a sort of powered glider type thingy, so sugges a fairly large prop ( maybe 10 X 6 or so ) and an outrunner of lowish Kv - with a 3s LiPo this setup would give you around 160 - 200 watts or so....NICE!

At that power on the 3s you would only be drawing about 15 - 20 Amps max, so a lipo of about 2200 mah of maybe 15 -20 C would be fine ...very common size and cheap as chips these days.

However David ( who knows the model ) seems to think its more of a hot liner type, and now that Timbo has actually bothered to read the article - it seems it is a bit more of a hotliner - Inrunner may be easier to fit too. However the review does suggest that the powertrain chosen will dictate its flying style and performance, so its up to you really!

Tim/Peter - I'm home now and the motor is here - a 16/15/6 from Puffin. It's an upmarket motor at £53 top quality and performance I should say. I did chat to John Emms about the set-up and we decided to go for a hot version. That said the model is one of those rare types that can do everything for everyman and some have used it as a trainer with a cheapie £5 speed 400 motor, some fly it with a mid-range set-up and some have put a  250 watt system in it

The original Terry had superb flight characteristics from a good flat glide to aerobatics.  The only problem was the strength of the wing: mine finally met its demise in a sharp pull out from a power dive done to avoid our large flock of lapwings, or plovers; they always hated the model and took off as soon as I started flying with it in order to start a dog fight!  Other models are not as threatening for some reason.  They always chase wedge tail eagles and other  raptors.    The wing snapped in half, which is reparable, but the motor/fuselage did not survive the plunge into hard ground.  Has the new Terry a good spar in the wing?

With regard to electric power trains, is there a simple table which will tell one what range of rpm to expect for each prop size?  Having read recently, (special issue RCME 2005 I think) that a given motor/bbattery set up will always attempt to mainain the revs for each prop size, I am once again in trouble trying to understand  how all the facts relating to component choice come together!

Many thanks.  No wonder there isn't the information around that I was looking(hoping) for!  I gather therefore  that experimenting is the way to go.

Just ordered one for a 'keep in the car' plane. I always liked the shape of this little plane (won't be putting the Terry stickers on though!)

Got a spare Mega 16/15/4 motor, 11.1v 1800mAh Lipo and a Castle Creations Phoenix 25 ESC that should do the job. Will try the 6/3 Folder for a start, but think a bigger size will be best..... Then I'm thinking of adding alierons later and carbon bracing the wing a little more.

First flight ysterday evening - went very well - a nice aeroplane and very fast on the set-up but not too much to handle. She makes a lovely whistling noise on a motor-cut fast fly-by - just like a large glider. Need some more fly time yet but first impressions very good ......which wont come as suprise to the Terry fans out there

We got a nice set of pics and here she is...

Had a couple of flights on mine now................. I believe I've found the melting point of Solidpor/Elapor

 A word of warning about jamming a hot brushless motor into the front of a Terry. There is NO cooling airflow around the motor, indeed the motor will be sitting in one of the worls best known insulators! Granted, I fitted a 3 turn Hong Kong eBay special with no through cooling. Does have a nice fitted heatsink to it, not that it can do any good in the Terry.

I think Daves choice of a mild-ish 5 Turn motor is the best option. Or leave alone and fit a 400/480 brushed job.

Terry's not dead, but I have had to make a larger hole in the fuse and construct a thin titanium cage mount that allows good airflow all around the motor (Working at Rolls Royce Aero Engines has it's ups)

 Ian F.

How does she fly? Like a little hotliner really. After a bit of trimming and a few circuits I tried started to wring her out a bit. Unlimited vertical and huge loops. The roll is as expected with rudder only, but I used longer servo horns than recommended to get a lot more throw so it will roll, but I only tried it at height. Low fast passes are great and she really whistles ! But turn the taps off and it'll stooge around at 1/4 throttle, and I even caught a thermal or two (we fly from Rolls Royce Hucknall's wartime concrete runway)

I'm well impressed, and now the cooling proplem is sorted it's a little gem. Perfect for beginners on a soft setup or hooligans on a brushless system.

 Still not sticking the Terry stickers on though.......

 And no, I didn't steal any Titanium. It all came out of the scrap bins

 Ian F.

Yup, pretty much the same Ian - she's really grown on me these last few weeks. Vertical performance is good and she'll keep going and then tear down for a whistling pass. I did contemplate ailerons but the more I fly her, the more the model seems somehow 'right' like she is?

My motors been just fine and I'm getting good 20 min flights when climbing and gliding (on a 1100mah Li-Po)

I have put a Vortex 28.35.2500 inrunner in the front of my Terry, about 24 quid from All Electric R/C, takes about 16A at full chat from an 1800 3S pack with a 6x3 CAM folder. Not as quick as your Mega powered Terry - but I'd got the Vortex (recycled from a Zagi), and they're half the price. Nice little plane to keep in the car and not so noisey as my FunJet.

I did try with a brushed 400 initially, but although quite pleasant for whiffling around in quiet conditions doing low and slow close-in passes, touch and goes, brushless inrunners are the way to go.
