Mine came today - holy that was fast! I may have to move it to the front of the build list.

I ordered a BP A2810-11, which is roughly equivalent to the recommended Rimfire.

Being a bit perplexed by the weight of this model I decided to do a comparison with my still unbuilt Electrifly Sopwith Camel.
Camel----------Stearman
Fuse......3.6oz----------8.5oz
Wings....6.4oz----------8.2oz
Parts.....5.4oz----------7.9oz

Total....15.4oz--------24.6oz

Since the Stearman fuselage is 4.5 inches longer, it's natural that it should be heavier, but over 100% heavier??? This obviously throws the CG aft, which, combined with the weight, is why the need for the heavier battery and motor. As mentioned above, the wing loading is quite high - and 2.5 lb is crazy for a 36" model. I'm going to try to build this one lighter with less motor and battery, which could save about 3-4 oz in weight. If I need to add weight to achieve balance, I'll add it under the motor box - as far forward as possible. Other than the weight - I am really pleased with this ARF - looking forward to assembling it

Hey Park Flyer,

Sorry it took me until today to see this thread again but, I am sorry the motor that you selected has just too many high Kv's as a motor spec. and reason why Gerry's SUPER TIGER 0.10 was just as high (1250Kv)!!

Here's your motor selection:
http://www.bphobbies.com/view.asp?id...7&pid=D1748438

Recall that Gerry changed out his motor to the E-Flite 480 (910Kv) and he has flown it for several flights with great results using the APC "Slow Flyer" 10 X 7. ( yes, you can use the APC "E" 10 X 7 as well).

I believe that someone at Great Planes / Tower made a big mistake on the selection / recommendation for an Electric Power System for this model!! Gerry's setup drew almost 29 AMPs (Current) at wide open using the SUPER TIGER 0.10 (1250Kv) while swinging the APC "Slow Flyer" 9 X 6 !!

I hope you can consider a motor similar to the E-Flite 480 (910Kv) "or" look into the BP A2217/9 motor as I have this same motor in various models and it is a very good motor with just (950Kv).

Park Flyer,

If you look inside the Tail FUSE boom carefully, I believe you will find the reason for the weight and Gerry and I believe that the Formers used for the Tail Boom are made of Plywood instead of Balsa. I do understand that Balsa is very expensive but, on a model ARF known for quality?

Gerry and I might be incorrect for our assessment here but, then, why else would this model be so heavy?

What really got me think about a different motor is just the sheer size of the 2810-11 - it's a big fat motor that weighs almost 3oz.

BP hobbies ships fast too, so I've already received the BP A2810-11. As it turns out, I have another model with a 2217-9 and that is exactly the motor I'm thinking of using on the Stearman - glad to see that someone has already done similar. In fact, I'm going to swap the 2217-9 out for the 2810-11 on the other model - an e-converted .15 glow model, so I will be testing that one later today.

It is a wonderful covering job for an ARF. No doubt.

Can someone tell me which side of the n-strut is forward, long or short side?

Thanks

I would guess the short-side to the front to account for the increased thickness of the wing.

Hi Guys!

Like to share Video Capture of today's early morning action!

Gerry enjoying his Great Plane Super Stearman during a super Sunday Morning at a place we all affectionately call "EDWARDS" due to the wide and open space with smooth concrete surface!

This is a great plane at a good price. I presume it will catch on and become more popular.
