Yeah Andy and I spoke Rich, thanks
he is looking in from a distance, the problem is, I am best part of £100 in with the subsonic, £30 tx, now £20 corona rx, and a few other bits and bobs, and today was a disaster!
Range issue, still only 6 feet or so, so looks like the tx is a problem. A tried some surface running close to bank, anything over a snail pace and it wants to dive, even with a degree of up elevator on the rear planes, so couldn't even manage a surface run. I tried fitting the static front planes, it helped, and looked better, made it more stable. I have a long way to go here, as pulling the wtc out at lake side isnt ideal. I have nowhere near enough travel on either planes, or rudder. Don't have any more room in wtc to extend servo horns, so will have to cobble something up on the planes to give more travel. I was thinking of making the rudder and planes bigger, and fabricating a linkage from front to rear planers so all 4 work, thinking this might help with surface running.
Its going to be too big a job operating front planes from the servos in the wtc, I would have to buy a new endcap, rods, tubes and seals, then the linkages would run past the battery, which itself will cause problems on battery removal for charging.
I removed all electrics from sub, fitted to a boat, like I should have done in the first place, back to lake, and its got very poor range, so must be the tx. Tried fresh batts in tx, and tried different channels with throttle in case the tx pots where bad, still the same, looks like its another purchase, another tx
. This cheap "fun" project is now becoming a chore!
