View Full Version : Hobby Hangar OV-10 Bronco conversion

09-20-2005, 07:51 PM
Just ordered my Bronco from Hobby Hangar. I was looking to see what the best combination for motors would be. It needs .25 IC sized conversion, so I was thinking of an AXI 2820/10. Any others to consider? Hyperion, Hacker, etc.?

I was also thinking about two mega 16/25/6's.

If it were me, I would use the Hacker motors. What do you think the AUW will be?

I as long as you can keep it to 5-6lbs I would think these would do the trick:

I would shout for the a30-16m or 12m. But if you will be heavier, you can go with the larger (longer) motors for sure.

Take a look at my baby! I have twin s400's in this now, but will be using the hacker a20-22l's in it for 15amps per side. Should be near the 400w range and at around 54oz or so. It flies good now, that will be even better!

Mike, I'm figuring around 5.5 to 6.5 lbs. They're doing a conversion now with the Bronco, and are using the A30's. Where can you buy the Hackers? BTW, beautiful plane, and great thread.

Thanks man!

You can get the hackers directly from their www.hackerbrushless.com or from vendors like:

Definately an option. I'm also thinking about the long can mega. I'll have to reserve my decision until I actually see how far it is from the firewall to the cowling.

How about the HET Typhoon motors?

Hey, just thought of another motor - the new astroflight 19. Check out: http://www.astroflight.com/e/env/00011T8vI38kd24Ctc445j9/store/store-Brushless.html?link=/store/store-type-tem.html&item=products:af-819m

Might be an option.

did one from the kit a few years ago. At the time had two geared endo's and two 10 cell sub C packs. A little under 8 lbs ready to fly. Did a lot of lightening, but also added retracts. Flew SUPERBLY. Currently it's sitting at the house without electronics, as it's been for a couple years, but I just got a couple A30 L motors for it and it will have lipos. Rough calculations show it should be about 6 lbs with the lighter motors and batteries. Was at Hobby Hangar at lunch yesterday and helped them program the ESC's for the bronco their doing with A30 L motors and 3S2P packs. This is a converted arf, and they did add retracts. It's 7.5 lbs if I remember correctly. roughly 300 watts per side (not running the A30's very hard,.. only 28~29 amps each). The pull is far better than with 25 glows so I think it should fly really well on the maiden this weekend. I know my original with 400 watts per side into brushed motors was really phenominal.

Thanks! I am going to try the Astro 19's. Looks like it will pull approximately 300 watts per side also. I'm looking forward to hearing about the flight this weekend, hope you are going to be there. I find it kinda strange that the few comments you do read about this plane are overwhelmingly positive, yet there doesn't seem to be that many out there.
