Large Model Association Forum

Helping a friend who is fitting a set of air retracts into a 113" span Vailly Aviation FW 190, one of the connections for the air lines is on top of the actuating cylinder and when fitted there is only around a 5mm gap between this connection and the wing sheeting (see photo), Note the cylinder moves slightly as it actuates the locking mechanism so we are concerned that a tight radius on the plastic tubing here will cause wear on the wing sheeting or eventually lead to the plastic tubing being fatigued and fail.

Should we be concerned? if so any suggestions.

On another picture we found of the same model the connections are on the cylinder ends, but we'd rather not have to disassemble and re-machine the cylinder if possible.

You will find these on eBay in 3,4,5mm thread sizes

Alan thanks, the 90 deg ones would probably be fine, but we can only find them with a 5mm thread, which looks too large. However we think we can bend the plastic piping so it won't foul the upper wing sheeting so are going to investigate that further, if that looks like it could be problematic then we'll do a bit more searching.

What thread is it? Traxas do an M4 https://www.minicars.se/en/artiklar/pre ... egree.html

Contact Dave Brown at Premier Retracts, he has stock of the right angle nipples.
