Graupner SU31?
 

Anyone have the Graupner SU31? I have thier CAP 232 with a TT pro 61 and love it! I was thinking about putting the Magnum 91 four stroke on the SU31 with a 3 blade prop. The 91fs weighs less then the TT pro 61.

ooops ... wrong plane!

Yes, I have the Graupner Sukhoi SU-31. Graupner kit is outstanding. And so are the flight characteristics. I have powered my Sukhoi with an OS 70 Surpass.

The engine gives the plane enough power, in my opinion. Maybe not enough for a hover, but for normal aerobatics I couldn't notice any problem.
It files very good. The only problem i have noticed is that the screws for the cowling-, and the belly-pan came loose in flight caused by the vibration.

Here are some pictures of my Graupner Sukhoi

I believe that the Graupner kit is made bt Blackhorse & thetre is an extensive trail of comments about Blackhorse models in this forum

Britbat ... you are most correct ... its a Black Horse but with a different colous scheme only. I am flying the new batch of BH SU31 and they fly well enough on a TT46 Pro. I think with a 70 sized 4C it will be great. The plane has no real bad habits.
