RC MD 500 repair

[Guest]

A mate has bent his 50 size MD 500 and as he can not work with glass I will be fixing it for him and extending the boom by 160mm for the longer 600 size mechanics

The inside of the boom had to be repared with a paste of epoxy and cotton flox to get an even surface to put the glass tape on.

I also made a plug to mold the 160mm boom extention over. I used a balsa frame with sheet balsa to give shape. The pink stuff is PVA to help get the plug out again........does kinda look like a strawberry lolly LOL!

The glass over the plug is 2 layup of 63gr and a single layup of very fine glass to smooth it out a bit.

When cured I will fill and sand it and then attach to the rear of the boom. Then the "fun" begins, to try and bland it all in so that there is no visable seam and not add to much weight in the prossess.

Thanx. The repair is the easy part, making it as seamless and pretty as I can will be the hard part!

Judging by the work on view from your last helicopter thread, the problems shouldn't be too much to overcome.

Thanx , the haslle with these type of models is that tehy are super glossy and that shows up the slightest imperfection! That is why build military plastics as they are usually matt or satin LOL!

Got the extention on and mostly blended in and the broken bits mended, some little spots to still fix up but coming allong nicely.

Looking good - The next hardest bit will be to match that paint !!

[Guest]

Strangly matching the paint is not my major worry, the paint guy here is darn good at doing it by Mk1 eye!

Thanx, pitty about the slight step where extention meets boom, but no other way of safely making the joint internally, just plainly no space to do so and with these things I do not gamble.

Especially if the ovner has invested a good 1500 UK squidd in it!
