Here it is! The build video for the FT Old Speedster. If you are firmiliar with the FT Old Fogey this one will be a breeze.
The polyhedral wing design allows the plane to self right itself in the air.
Remember, it is hip to be square. Always double check your angles!
Here, Josh assembles the control horn for the rudder. If you ever need extra control horns, they are available in the store!
Right before the attachment of thepower pod.
Last but never least, WHEEL PANTS! These are included in the kit but are also available seperately if you would like to add them to your existing planes. Check them out in the store!

Who knew that a Swedish friend could be replaced by a square of foam board? ;)

the tail is better at controlling the attitude of this configuration.
if you made a dihedral or straight flat wing with 0 dihedral,it would work better with ailerons.
sorry to ramble

Iguess I will end up tiling this one!
GREAT VIDEO!

I've build my first one and centered the wing. Once I fly it I will see how difficult the left pull is.
A left wing measurement may help. please!

The total wing w/o tips is 19" long.
From the port side of the fuselage mark (left wing looking from rear of the airplane) to the left joint is about 8-3/4" + or - (This plus or minus shouldn't be for my experience no more than 1/8")
I hope this helps.

I built the plane with larger wing span, 40'' in total, and 0.5'' less dihedral than the original on the wing tips. I have a 2212 motor at 1000kv, 3s LiFePo. Flies right off my hand but there was a left tendencie. I first did not glued the wings to try different length of offset to correct the problem. I tried offsetting the thrust angle too; downward and slightly right. I simply used rubber gasket (like those on prop savers) and put it between the firewall and the motor. It gets squeezed as it gets the slack when you adjust the screws. After a few flights (crashes), I finished gluing the wings with a 1.25 left offset wich seemed to me the best. I still got left tendencies but I was able to turn right. Now, i it is maybe a trim issue. I finally crashed after a 2 min flight so I cannot say for sure.
It seemed to me that adjusting the thrust angle makes better results than offsetting the wings when correcting the left turning tendencies. Offsetting the wings when using smaller dihedral seems necessary.
Hope it helps.

Wing is kind of flimsy and intents to fold, also the tail surfaces stress the rear of the fuselage to the point of foam fatigue, I have photos but don't know how to post.
I suggest two main improvements:
1.- Reinforce with doublers the rear last 1/3 of the fuselage.
2.- after the wing is installed in the fuselage and glued add three bulkheads one under the leading edge of the wing, one in the center fold and one at the bottom of the trailing edge, all glued to the wing and fuselage to act as reinforcement, weight is not an issue here, as three pieces of foam add no such a terrible weight and will make the structure stronger.
Said that, I had lots of fun, plane flies awesome and slow, giving lots of time to correct in flight to adjust any bad tendencies but was ended by the fuselage fatigue.
I guess this might help someone interested.
Thanks.

I built an Old Fogey and that's lot of fun. I'm now interested in the Old Speedster...
But the asymmetrical wing annoys me a little....
Instead of extending the wind on one side, has anyone tried to angle the motor a little bit? :-)

What are the two strips of poster board for, about 1" wide that are on the plans with the canopy and turtle deck cutouts? Jack

I am thinking of of putting a larger motor with this plane so that I could use the same power pod for larger planes. I am thinking of using the Emaxx GT2215/09 from the PowerPackC or something equivalent (i.e. Turnigy D3536/6 1250KV, 500W, 102g)? Would the plane flip towards the left or become hard to control with a larger motor?
Thanks for your help!!
