Think of the binding as fingers wrapped around the wire - you would always grip a rod tighter holding it a clenched fist rather than squeezed between straight fingers and thumb*....

Hi Tom

I have to agree 100% with the Colonel, if just CA'd in place I would expect the undercart to fail at the first landing. The binding is important and I strongly recommend that you add it.

Oops I better had then! Thanks for that, I will add the binding when I get home. On the diddy little things i normally do there are tubes or slots on them for thee undercart. No excuse for me assuming it would do. See, I am a novice and need advising, even if I am 43!

Third those comments from the Col and SD. I usually cotton bind and coat with slo-epoxy. Works well for me.

All bound now, used cotton and due to a quirk of construction I was able to fit a 1/32 x 1/8 th strip of balsa on the outside edge over the binding so the tissue will have a smooth surface to go over. If I'd bound the wire to the bulkhead before assembly as you are meant to I wouldn't have needed to but because of the undersized I/8th stuff I've used and the happy coincidence that I added that pair of cross members after the bulkhead was fitted so they were flush with the inside of the frame not the outside I've sort of got away with it.

What I need to do is get hold of another (or find the one a kids hidden) of those handy six inch rulers with the slots cut out for quickly measuring balsa rather than believe whats written on the tube they are in!

Just this hour received the consignment of Jap tissue from Shortys Basement! Just when I needed it!

ATB and thanks!

My over enthusiastic sanding of the trailing edge has made it nearly 1/8th of a inch narrower than it should be, oops, but I will have to live with that now.

I have added some 1/16 reinforcing ribs to the centre two sections to take the presure of the rubber bands that will hold it on and have just given the areas I will be sticking the tissue to a good coat of full strenght dope. I'm realy not looking forward to covering the nose on this one, I may have to look up wet covering techniques!

Hi Frog and HNY..Your building quality and pictures put my poor efforts in the shade, still you had a kit to start with. Vis the undercarriage hope it all holds together thread binding to the former would help. Cheers. SJ.

Yup the kit made a BEEEG differance and if you got up close its a bit rough in places I can assure you!

Covering the nose has been as bad as I thought it would be, I don't think it will affect it much performance wise but I have learned plenty from my numerous mistakes.

Note all the glue covered cotton that is now holding the under carriage on!



I'll do some of the nice easy covering tonight after the curry we just ordered.

And a very good curry it was too!

I've done a bit more, theres some small wrinkles that I may have to sort but its gone quite well, I can'tbelieve how many sheets of tissue its taken! Normally I have stuff left from two!



The fuse'' has had 2 coats of 50/50 after shrinking with watered alcohol, as has the fin, The stabiliser has had one coat so far and the wing I'll do tomorrow.

PS does any one have the instruction sheet that should go with the plans? Replikit doesn't supply one.

Tom,

What is the difference between the Contestor and the Competitor? From your photos, it looks like an identical sibling except for the tail.

Somewhere I thought you might have mentioned the Contestor being larger...
