Sir dates extended till 07th Sep. Will be sad not to see this in the finals. Try making it time permits by then. May be just replacing with a bigger canopy/wing should do the trick. All the Best Sir.

Col this anyway was an experimental build. I plan to make the final trike with carbon fibre rods after a little more experimentation with the servo layout. This project is not going to die but will take some time. Will keep updating the progress on the forum

The Rogallo wing is too interesting to forget about it. The wing can be mounted on different types of aircrafts. So while the trike build is kept in abeyance, located a suitable project on RCGroups for a pusher plane for a Rogallo wing. Since I already had built the wing, and is larger than used in the project on RCGroups, I rescaled the plans to suit the dimensions of my wing. So trying my hand on this build for the Sweepstakes. The resized plans were drawn today evening.

Started fuselage build by cutting a 45cm long piece from 12mm balsa and another piece of 26cm from 6mm balsa for the tail. The pieces are 25mm wide but taper towards the tail. The two pieces were joined at an incline so that the tail comes in the prop wash.

What happened to the trike you bought on the forum a few years ago?

@Iyer. I never bought a trike. Dont have one.

Made tail feathers using a mix of coro and biofoam The stabilisers were made from laminated (two pieces of 3mm coro) while the elevator and rudder were cut out of 6mm biofoam. Bothe were covered with orange tape to match the colour of the wing.Pinned hinges were used for the control surfaces.

The pylon was made of two pieces of 2mm lite ply and balsa. The top was inclined at 14degrees and crossbraces were attached for mounting the wing.

This looks a featherweight compared to the previous one.
Will you try a smaller motor and smaller battery?
Let me know if you need a smaller motor, prop, esc, battery.

Btw, i remember calling you (3 or 4 years ago?) to enquire about the trike you were (in the process of) buying from someone on the forum. Perhaps a para sail? Couldn't locate in your posts. Maybe it never materialised. Or maybe it was someone else...

@Iyer
This is much lighter than the previous attempt. Aluminum is not the way to go.

The purchase of the trike off the forum did not materialise.

Trike rigged up and ready for maiden  Grin

Rigging the control rod for the elevator was complicated and had to use a bell crank.  Used carbon rods to keep the weight of the tail to the minimum.

The front wheel is also connected to the rudder servo for ground steering.

All in weight except battery is 490gms.

Maidened today. However the battery strap came lose at takeoff and battery slipped out, disturbing the CG. The trike made an emergency landing. Notice the battery dangling below the trike. Enjoy the maiden.
More flight videos later.

@Sundram. Yes Col, it was an interesting experience building a trike. Need to do more flights to understand the flight characteristics of a Rogallo wing. The target is to build a weight shift trike. You should also try to make one and share your experience.

@foamybuider. Though I wish I could be a regular flyer at Hoskote, but personal issues at home keep me tied up. For past so many years I am keeping my models ready for a sunny patch in my post retirement phase. Angry

WANTED I need a few old motors for their bearings and shaft for making the swing mechanism for the weight shift  trike. Anyone willing to part off with old burnt motors?

Thanks Sanjay ji. Just following in your footsteps.

Unable to go to the flying field for more flights. However the trike has been sitting on my dining table just to remind me to go. Cry
