Hey Peter.. what/where should I get a prop (prefer folding) to suit the 2600 KV Neu DD setup?

BM,
I'm no expert but I think there are 4 options:

1) Run a conventional 4.75 x ? APC Pylon prop. Assuming this is for your X Plane, getting a 32mm spinner might be a problem but 30mm diameter ones are common and should work and look not so bad.

2) Run a GM folding pylon prop in 4.75 x 4.75: http://www.soaringusa.com/product.ph...&cat=60&page=1. Again I think these are 30mm diameter so it won't be perfect. Although I haven't read anything terribly positive about their efficency compared to a conventional APC. Jacko's done some posts as he has one plus the 5 x 5 version which would be worth a search.

3) A double over pitch folder? I notice the effective kV of the geared setup I've come across are around 600rpm/V - Kira 480/31 5.2:1 is 596rpm/V, B40-11L 4.4:1 is 619rpm/V and L3038- 4200 6.7:1 is 627rpm/V - so you could mount a Kontronik 4.2:1 gearbox on your 1115/2D to give an effective kV of 619rpm/V that would then allow you to run a high pitch folder I suspect. Admittedly you wouldn't be able to push it as much as a lower wind/higher kV motor but does that really matter?

I've never seen pictures of a Neu equipped with a Kontronik gearbox before but recall Richard hinted that he had done it successfully recently and was willing to help out others: http://www.rcgroups.com/forums/showp...0&postcount=61 & http://www.rcgroups.com/forums/showp...postcount=1642 Surely if the mounting holes line up with the adaptor plate, it should be easy for 4.2 & 5.2 ratios. Maybe there is a trick with the smaller pinions on the 6.7 ratio gearboxes that Richard is referring to?


4) Return your 2D to Bruce and exchange it (and some extra cash!) for one of the geared motors he is starting to stock.

Also it's easy to get a 32mm RFM spinner for Options 3 & 4 too! As for suitable props, I'm still searching: http://www.rcgroups.com/forums/showp...3&postcount=12


Frankly I still don't know what motor and prop combination to run as there is so little reliable information available.

Good luck!
Peter

Summit

Kontronik Kira 480/31 5.2:1, Koch 8.5 x 23 blades on 30mm RFM spinner, ICE 100 Lite and 5 cell 1800 all fits with no room to spare. Even had to take the RX out of its case and put it in heatshrink tubing!

It Flys!

Snuck up to the field late this afternoon for the maiden and surprise surprise it flies!

Only did one flight as it was overcast and couldn't see it on landing approach and still haven't seen it land when it went past me at a rate of knots to the other end of the field even with spoilers deployed! Consequently I quitted while I was ahead.

Flies like its on rails particularly when in a banked turn as though that's it natural habitat. I just need to do some more trimming to stop it climbing under power.

With the motor and prop combination I'm using it barely accelerated from my hand launch and takes a while to get up to speed.

I was hoping to post some ICE data logs but only managed to collect some really weird and unbelievable data like -35F esc temperature and a power draw at WOT of 15 watts.

So I'm pleased that's over and can start scheming about more grunt!

No! To expensive for that sort of thing BM!

I'll keep that sort of carry on for Hobby King Fun Fighters until I get used to that notion of flying!

Don't be surprised if a couple pylons crop up at the Rebel field, your fun fly day certainly made an impression on a few of us. We've even came up with our own variation where the rules require a figure 8 circuit around two pylons. Should be spectacular to watch............
