hello all

I am interested in this plane .

I would like to build it as light as possible while still having retracts and flaps. So no lighting set , no cockpit kit , monokote finish .

I would like to ear from folks who have already built it and ear your engine and retract choice ...

I am interested in the new os 75 AX ... enough power ?

I also saw that tower offers a more economical alternative to the custom robart retract set ; this cheaper version also seems to come from robart but probably more 'plain vanilla'.
Did anybody ever try it ?


thanks

OK, Here's my history... Built three of them.

Most of the Bonanzas on RCu seem to be coming in at around 15 lbs or so depending on level of detail. Mine is in the 14 lb range with glass @ painted finish, retracts, and OS 120 4 stroke.
Also, there was a necessary shift of the CG based on feedback from top flight and those on RCU. Here is what I found:
When assembling, the V-horizontal stabs (v-tail saves weight) based on the supplied formers were too little incidence (leading edge too far down by about 4 degrees). The plans however, indicated 2 degrees and this seems quite accurate. This would require either down elevator to maintain level flight or more nose weight. I revised the formers to get back to 2 degrees and this meant that I only needed minimal noseweight to balance per the original CG location.

I really like flying this plane, but it does not like crosswinds and with less yaw control (v-tail) it is challenging to fly. But, you rally have to love that v-tail.

Good luck

I have built 2 of them, both v tail. To keep it light put the battery and airflask as far forward as possible. To get the cg with most of the recommended engines you have to add up to 1# of weight to the firewall. I have used a saito 100 fs. It gives plenty of power for scale plus flight. The vtail flies like the fullscale especiall the tail wag. I used a royalevo radio so the set up of elevator flaps and nose gear steering was a breeze.

Sedick , by 1# , do you men 1 pound ?
