MattyB Posted October 16, 2023 Share Posted October 16, 2023 Why do they often put the wheels so far forward on vintage designs? It must give some “interesting” ground handling characteristics. Is it to give a degree of protection to the prop on landing when they are flown as free flight models? Quote Link to comment Share on other sites More sharing options...
Martin Dance 1 Posted October 16, 2023 Share Posted October 16, 2023 The very forward undercarriage was to allow ROG (Rise Off Ground) takeoffs to be made reasonably reliably, even so you had to take off into wind. 1 Quote Link to comment Share on other sites More sharing options...
Robin Colbourne Posted October 16, 2023 Share Posted October 16, 2023 The Quaker Flash (67" span) is a scaled down Flying Quaker (84" span), which was originally released as the Megows Gas Model. Delicate wooden propellers plus slender, petrol engine crankshafts with extra length for the contact breaker gear, meant a noseover could be an expensive business. If doing a rise off ground take off, the model would already airborne before ground handling was a concern. 1 Quote Link to comment Share on other sites More sharing options...

All the 3 channel models can have interesting ground handling as the dihedral will also cause the model to bank, but if you take off into wind they take off very easily. For taxying though the forward undercarriage puts a lot of weight on the tail skid, so I find myself using down elevator and a blip of throttle to unload the tail and bring the model round. BTW we had a lucky escape on the last flight, the rudder came unstuck from the elevator and was only held on with the covering so was flopping around, but fortunately we were able to maintain control.

This extract from a 1937 publication (obtainable from https://rclibrary.co.uk/index.asp )will give some insight to the thinking of the time: Edited October 17, 2023 by John Lee Source added Quote Link to comment Share on other sites More sharing options...
