stevron Posted March 28, 2018 Share Posted March 28, 2018 As many will know I own a Brumby610 Lycoming powered model and I was wondering who loves their Brumby and who is not as happy and why? I have had a love hate relationship with mine to start with , it’s been a long haul and I have been frustrated by continual faults for which most have been rectified (eventually), that being said , I still find enjoyment to go for a fly . Last week I found a crack in my replacement prop spinner, both the nose cone and the mounting plate. Communication with the installer has not been effective to locate a new one as yet , I may have to go out side the current supplier to find replacement for the replacement, at this rate I would better buying 2 and keep one spare. So, Come on , let’s hear how the Brumby’s are standing to the rigours of time and use. Link to comment Share on other sites More sharing options...
dazza 38 Posted March 28, 2018 Share Posted March 28, 2018 A flying school I used to hire aircraft from sold a Rotax 912 powered high wing not long after buying it. The reason was it had a very poor climb performance sure they could have put a finer pitch prop on it but cruise speed would have suffered. Pretty heavy empty weight.

Mick Posted March 28, 2018 Share Posted March 28, 2018 That spinner cone looks like the bolt heads have worn into the fibreglass. Were there washers on those bolts? Link to comment Share on other sites More sharing options...
bexrbetter Posted March 28, 2018 Share Posted March 28, 2018 That spinner cone looks like the bolt heads have worn into the fibreglass. Were there washers on those bolts? Agree, use double washers, the largest diameter practical but thin, and a normal washer on that one to spread the load. Use crappy punched washers that have a predominate curved smooth side, and use that on the fiberglass surface. Link to comment Share on other sites More sharing options...

I put thin nylon washers under most metal to fibreglass to reduce the chance of damage occurring. Link to comment Share on other sites More sharing options...
Downunder Posted March 28, 2018 Share Posted March 28, 2018 I priced a Lycoming Brumby in 2012. Sticker price had me running away hard and fast...... If the same price was offered in 2018, I'd still be running... If you paid what I was quoted, I'd expect silver service..... Link to comment Share on other sites More sharing options...
stevron Posted March 28, 2018 Author Share Posted March 28, 2018 Good try on the bolt heads but that is/ was not the problem ,the problem was / is the front support did not fit properly and allowed the spinner to move through the torque of the engine and then the spinner was out of balance and that’s why it split the backing plate as well , yes the spinner was fitted with washers and it’s a spun metallic spinner Link to comment Share on other sites More sharing options...
stevron Posted March 28, 2018 Author Share Posted March 28, 2018 Dazza , that’s a shame about the flying school as I thought Brumby designed their equipment to be an air craft most suited to flying schools. Well that’s what the advert refers Link to comment Share on other sites More sharing options...

dazza 38 Posted March 31, 2018 Share Posted March 31, 2018 See my response It didn’t perform as well as the Tecnams at the school hence it went.Mind you it was a bit like comparing a Apple to an Orange as the Tecnsm Golf take off weight is 544 KG and the Brumby 600 KG on the same power.

davidf Posted March 31, 2018 Share Posted March 31, 2018 You might try a dynamic prop balance also put nose con on a flat surface and see which way it rolls it will roll to heavy side, out of balance. Link to comment Share on other sites More sharing options...
Paul davenport Posted March 31, 2018 Share Posted March 31, 2018 An Air Master inflight adjustable pitch prop was fitted to a Brumby powered by a 912 and OKed by factory with spectacular results. Better climb rate and a 15 knts increase in cruise speed . The owner is very happy Link to comment Share on other sites More sharing options...
Raytol Posted April 1, 2018 Share Posted April 1, 2018 I always use the red fibre washers under the heads on a fibreglass spinner. Have not had a problem since doing it this way. Link to comment Share on other sites More sharing options...

I will electronically balance the whole system when I refit the new unit ,I wish it had been from the start as it would have saved time and money Link to comment Share on other sites More sharing options...
