RE: Hansa-Brandenburg W.29 ARF
I must say, I'd consider one even if I did have one the size of your nice 90" span one.. There was a point I wouldn't have thought of a smallish electric plane, but in the last couple years I've found these little guys to be a lot of fun for not a lot of work, money, and hassle at the field/lake. I can run over to the local pond at lunch time and get a few flights in, getting a daily fix of flying doesn't have to consume hours anymore.
Any how,, Engine install pretty straight forward, No mounting hardware is provided, so I used 4-40 Stainless steel cap bolts with blind nuts. There are lines scribed on the firewall so the X mount was used as a template. Hobby King Turnigy G15 950kv motor will be used. Powered by a Turnigy 45amp ESC.
Difficulty with the hatch/upper deck at the engine compartment design is it leaves you very limited access to the area you'll want to mount the ESC and battery. What I most likely will do is mount the dummy engine with magnets so it's removable easily to help with the battery placement, the esc is wedged in below the battery platform,, Just about impossible to secure it via zip ties as you really can't get your fingers in there, it doesn't seam to move around, so I'll leave it as is and keep an eye on it for chafing.
Float mounting also simple, 4 metal tabs are epoxied into the floats, they fit in nicely all the way and bottom out on something so no guesswork where they should stop. I did drill2 small additional holes before gluing to give the epoxy a good place to bite. (sorry no pic) I tossed the provided wood screws and used powder coated black servo screws for the cross bracing and 3mm screws with ny-loc nuts for main gear mounting.
At this stage the plane balances right on the spar, with a 3s 1800 pack midway in the battery area, no prop or cowl on yet, but looks like balance shouldn't be an issue.
I took it out for show and tell at our 1st annual Fall Fun Fly yesterday,, the typical jokes and ??s What is it? Your rudders is up-side-down, Yuk yuk,, but everyone thought it was cool. Only one other club member knew what it was.
