RE: Groovy 50 3A by The World Models
Sirgun and Crasherama
Yes SMC are a lone hobby shop dealing with customers direct, in fact I bought my H9 Miss America from them, I actually went down to the shop to collect it as I wanted to inspect the kit before purchase, good service and friendly, don't get me wrong service and freindlieness is also prevelant at Westons its just not somwhere I would reccomend you visit if your time is limited over here.
Winds over here are in the 25:30mph region at the moment, still did not stop me from trying the 3A with the 70 4S in it, I left the cowl off as I had not had a chance to start let alone set up the engine. Started immediatly I put the starter on it and idled fine no adjustments needed to the idle mixture at all, ran it rich for the first flight, you know within 10 seconds if you have a dog or a good aircraft when it takes off, this one is a goody, on the first flight the only thing negative was the amount of down elevator needed to maintain level inverted, loops where straight so lateral ballance seems Ok, Knife edge has some roll coupling, spins straight down will try flat spins later, stall in the wind non event will have to try in no wind conditions. Brought it in for a greased on landing which is hard on grass with the blustery conditions, very pleased with this flight and engine. Next took the last bit of lead off the bulkhead only 35grams sorry 1and 1/4onz and try again, difference in the needed elevator in inverted flight suprise suprise but still needed what I think is excessive movement, will look at the cofg position and report back after I get it back to the workshop. I did reinforce the bulkhead and undercarridge mount maybe I added too much weight will investigate. Second flight another good flight even without the lead the elevator is still not sensitive and ailerons are perfect at the designed movement, with the 70 4S in it running rich this is a much better aircraft, should have had it in first not the 60 4S, conclusion I think a 46 2S may be a bit marginal for the designed intent of this plane i.e. 3A schedule, but it will fly it but not with authority.
Will report back on the cofg location later today.
