Re: Converting EDF to turbines

Interesting, doing more research I found that Motion RC has taken down it's Roban A-10 page. I also saw a video of the Roban A-10 with 120mm fans and 2 x 12 cell 5000mAh batts with a wing failure.

It is a nice looking airframe but with a wing failure it might need a lot of work to convert to turbine. My MIG-29 has 120mm fans and 2 x 11 cell 5000mAh batts and runs 28lbs and took some extra work to convert to fans from the OS 91's. May have to consider another winter build project for my PST's.

received my engine today as well.

Didn't look at the serial number.

Had already seen one but still impressive to hold on to.

Also manged to pick up a Freewing F22 with two flights on it so the EDF $hit is coming out and the turbine conversion going in.

Re: Converting EDF to turbines

I guess that was part of my point about being heavy ; was with getting a C of G balance .
Would add more weight in the front pushing the weight possibly more in the 28 lb range with added tail and nose weight were the xicoy’s would Bring the weight down from the design weight of 22 or so pounds with the 120mm fans . Would definitely probably be a first and an awesome package.

A twin A10 would be awesome. Wonder if the PSTs would make it hard to achieve CG? I have a pair of J600Rs as well, but that’s a big heavy complicated bird. Kudos if you take that project on!

I saw a neat foamy conversion of a Freewing 80mm A10 where the guy put a single 45N inside the fuse tail boom (just where the nacelles mount to the boom) and used a pipe out the rear of the fuse. That seems a bit simpler...

Re: Converting EDF to turbines

Really thinking about it but no one has taken that particular A-10 and did a turbine conversion. It runs 4 times the cost of a foamy also.

Go for it Roy!

Re: Converting EDF to turbines

Those PST600’s are pretty heavy dudes . The Xicoy 45’s would make that fella perform for sure at under 400 grams each vs 1000 grams per PST 600.

Re: Converting EDF to turbines

Motion RC now has the Roban A-10 for 120mm Fans. Wonder if a couple of 14lb turbines would be an alternative? I've got a couple of PST 600R's sitting around.
